Brown bears are found in Alaska and western Canada. They are first cousins of the grizzly, each belonging to the species Ursus arctos. The chief difference in them is size, as brown bears on the average are slightly larger. A full-grown male may weigh 1,500 pounds and stand 9 to 10 feet tall. Like bears everywhere they are creatures of habit that tread the same trails year after year. Brown bears have three gaits: an even, deliberate one that takes them over rough or boggy ground at a steady clip, a quick shuffle, and a fast gallop. They are not only surprisingly fast, but also, for such huge beasts, amazingly inclines. Fishing the streams in summer, they pounce on swift-moving salmon and snatch them with almost simultaneous movements of their paws and mouths. Brown bears are excellent swimmers and love to loll and wallow in the water on warm days. They are also curious and playful. Most manifest a fear of humans, but Alaskans prefer not to test these creatures and usually carry noisemakers of some kind to warn the bears of their presence.

The Association of Southeast Asian Nations or ASEAN was established on 8 August 1967 in Bangkok by the five original Member Countries, namely, Indonesia, Malaysia, Philippines, Singapore, and Thailand. Brunei joined on 8 January 1984, Vietnam on 28 July 1995, Lao PDR and Myanmar on 23 July 1997, and Cambodia on 30 April 1999. The ASEAN Declaration states that the aims and purposes of the Association are: to accelerate economic growth, social progress and cultural development in the region and to promote regional peace and stability through abiding respect for justice and the rule of law in the relationship among countries in the region and adherence to the principles of the United Nations Charter.
In 2003, the ASEAN Leaders resolved that an ASEAN Community shall be established comprising three pillars, namely, ASEAN Security Community, ASEAN Economic Community and ASEAN Socio-Cultural Community.
The ASEAN Vision 2020, adopted by the ASEAN Leaders on the 30th Anniversary of ASEAN, agreed on a shared vision of ASEAN as a concert of Southeast Asian nations, outward looking, living in peace, stability and prosperity, bonded together in partnership in dynamic development and in a community of caring societies. ASEAN Member Countries have adopted the following fundamental principles in their relations with one another, as contained in the Treaty of Amity and Cooperation in Southeast Asia (TAC):
• mutual respect for the independence, sovereignty, equality, territorial integrity, and national identity of all nations;
• the right of every State to lead its national existence free from external interference, subversion or coercion;
• non-interference in the internal affairs of one another;
• settlement of differences or disputes by peaceful manner;
• renunciation of the threat or use of force; and
• effective cooperation among themselvesWhich principle does not belong to the Treaty of Amity and Cooperation in Southeast Asia?

Commuting is the practice of travelling a long distance to a town or city to work each day, and then travelling home again in the evening. The word commuting comes from commutation ticket, a US rail ticket for repeated journeys, called a season ticket in Britain. Regular travellers are called commuters.
The US has many commuters. A few, mostly on the East Coast commute by train or subway, but most depend on the car. Some leave home very early to avoid the traffic jams, and sleep in their cars until their office opens. Many people accept a long trip to work so that they can live in quiet "bedroom communities" away from the city, but another reason is 'white flight'. In the 1960s most cities began to desegregate their schools, so that there were no longer separate schools for white and black children. Many white families did not want to send their children to desegregated schools, so they moved to the suburbs, which have their own schools, and where, for various reasons, few black people live.
Millions of people in Britain commute by car or train. Some spend two or three hours a day travelling, so that they and their families can live in suburbia or in the countryside. Cities are surrounded by commuter belts. Part of the commuter belt around London is called the stock broker belt because it contains houses where rich business people live. Some places are becoming dormitory towns, because people sleep there but take little part in local activities.
Most commuters travel to and from work at the same time, causing the morning and evening rush hours, when buses and trains are crowded and there are traffic jams on the roads. Commuters on trains rarely talk to each other and spend their journey reading, sleeping or using their mobile phones, though this is not popular with other passengers. Increasing numbers of people now work at home some days of the week, linked to their offices by computer, a practice called telecommuting.
Cities in both Britain and the US are trying to reduce the number of cars conning into town each day. Some companies encourage car pooling (called car sharing in Britain), an arrangement for people who live and work near each other to travel together. Some Us cities have a public service that helps such people to contact each other, and traffic lanes are reserved for car-pool vehicles. But cars and petrol/gas are cheap in the US, and many people prefer to drive alone because it gives them more freedom. In Britain many cities have park-and-rids schemes, car parks on the edge of the city from which buses take drivers into the centre.As mentioned in the passage, commuters usually .......................

We live in a world of tired, sleep deprived people. In his book Counting Sheep, Paul Martin - a behavioural biologist - describes a society which is just too busy to sleep and which does not give sleeping the importance it deserves. Modern society has invented reasons not to sleep. We are now a 24/7 society where shops and services must be available all hours. We spend longer hours at work than we used to, and more time getting to work.
Mobile phones and email allow us to stay in touch round the clock and late-night TV and the Internet tempt us away from our beds. When we need more time for work or pleasure, the easy solution is to sleep less. The average adult sleeps only 6.2 hours a night during the week, whereas research shows that most people need eight or even eight and a half to feel at their best. Nowadays, many people have got used to sleeping less than they need and they live in an almost permanent state of'sleep debt'.
Until the invention of the electric light in 1879 our daily cycle of sleep used to depend on the hours of daylight. People would get up with the sun and go to bed at nightfall. But nowadays our hours of sleep are mainly determined by our working hours (or our social life) and most people are woken up artificially by an alarm clock. During the day caffeine, the world's most popular drug, helps to keep us awake. 75% of the world's population habitually consume caffeine, which up to a point masks the symptoms of sleep deprivation.
What does a chronic lack of sleep do to us? As well as making us irritable and unhappy as humans, it also reduces our motivation and ability to work. This has serious Implications for society in general. Doctors, for example, are often chronically sleep deprived, especially when they are on'night call', and may got less than three hours'sleep. Lack of sleep can seriously impair their mood, judgment, and ability to take decisions. Tired engineers, in the early hours of the morning, made a series of mistakes with catastrophic results. On our roads and motorways lack of sleep kills thousands of people every year. Tests show that a tired driver can be just as dangerous as a drunken driver. However, driving when drunk is against the law but driving when exhausted isn't As Paul Martin says, it is very ironic that we admire people who function on very little sleep instead of criticizing them for being irresponsible, Our world would be a much safer, happier place if everyone, whatever their job, slept eight hours a nightThe word "which" in the third paragraph refers to .....................

The issue of equality for women in British society first attracted national attention in the early 20th century, when the suffragettes won for women the right to vote. In the 1960s feminism became the subject of intense debate when the women's liberation movement encouraged women to reject their traditional supporting role and to demand equal status and equal rights with men in areas such as employment and pay.
Since then, the gender gap between the sexes has been reduced. The Equal Pay Act of 1970, for instance, made it illegal for women to be paid less than men for doing the same work, and in 1975 the Sex Discrimination Act aimed to prevent either sex having an unfair advantage when applying for jobs. In the same year the Equal Opportunities Commission was set up to help people claim their rights to equal treatment and to publish research and statistics to show where improvements in opportunities for women need to be made. Women now have much better employment opportunities, though they still tend to get less well-paid jobs than men, and very few are appointed to top jobs in industry.
In the US the movement that is often called the "first wave of feminism' began in the mid 1800s. Susan B. Anthony worked for the right to vote, Margaret Sanger wanted to provide women with the means of contraception so that they could decide whether or not to have children, and Elizabeth Blackwell, who had to fight for the chance to become a doctor, wanted women to have greater opportunities to study. Many feminists were interested in other social issues.
The second wave of feminism began in the 1960s. Women like Betty Friedan and Gloria Steinem became associated with the fight to get equal rights and opportunities for women under the law. An important issue was the Equal Rights Amendment (ERA), which was intended to change the Constitution. Although the ERA was not passed, there was progress in other areas. It became illegal for employers, schools, clubs, etc. to discriminate against women. But women still find it hard to advance beyond a certain point in their careers, the so-called glass ceiling that prevents them from having high-level jobs. Many women also face the problem of the second shift, i.e. the household chores.
In the 1980s, feminism became less popular in the us and there was less interest in solving the remaining problems, such as the fact that most women still earn much less than men.
Although there is still discrimination, the principle that it should not exist is widely accepted.Which of the following is NOT mentioned in the passage?

Very few people, groups, or governments oppose globalization in its entirety. Instead, critics of globalization believe aspects of the way globalization operates should be changed. The debate over globalization is about what the best rules are for governing the global economy so that its advantages can grow while its problems can be solved.
On one side of this debate are those who stress the benefits of removing barriers to international trade and investment, allowing capital to be allocated more efficiently and giving consumers greater freedom of choice. With free-market globalization, investment funds can move unimpeded from the rich countries to the developing countries. Consumers can benefit from cheaper products because reduced taxes make goods produced at low cost from faraway places cheaper to buy. Producers of goods gain by selling to a wider market. More competition keeps sellers on their toes and allows ideas and new technology to spread and benefit others.
On the other side of the debate are critics who see neo-liberal policies as producing greater poverty, inequality, social conflict, cultural destruction, and environmental damage. They say that the most developed nations - the United States, Germany, and Japan - succeeded not because of free trade but because of protectionism and subsidies. They argue that the more recently successful economies of South Korea, Taiwan, and China all had strong state-led development strategies that did not follow neo-liberalism. These critics think that government encouragement of "infant industries"' that is, industries that are just beginning to develop - enables a country to become internationally competitive.
Furthermore, those who criticize the Washington Consensus suggest that the inflow and outflow of money from speculative investors must be limited to prevent bubbles. These bubbles are characterized by the rapid inflow of foreign funds that bid up domestic stock markets and property values. When the economy cannot sustain such expectations, the bubbles burst as investors panic and pull their money out of the country.
Protests by what is called the anti-globalization movement are seldom directed against globalization itself but rather against abuses that harm the rights of workers and the environment. The question raised by nongovernmental organizations and protesters at WTO and IMF gatherings is whether globalization will result in a rise of living standards or a race to the bottom as competition takes the form of lowering living standards and undermining environmental regulations.
One of the key problems of the 21st century will be determining to what extent markets should be regulated to promote fair competition, honest dealing, and fair distribution of public goods on a global scale.The debate over globalization is about how .................

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Humans are bringing about another global-scale change in the atmosphere: the increase in what are called greenhouse gases. Like glass in a greenhouse, these gases admit the Sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the Earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significant of these gases – there is 25 percent more carbon dioxide in the atmosphere today than there was a century ago, the result of our burning coal and fuels derived from oil. Methane, nitrous oxide, and CFCs are greenhouse gases as well.
Scientists predict that increases in these gases in the atmosphere will make the Earth a warmer place. They expect a global rise in average temperature somewhere between 1.0 and 3.5 degrees Celsius in the next century. Average temperatures have in fact been rising and the years from 1987 to 1997 were the warmest years on record. Some scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is looming.
Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate changes are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such as the western United States, where temperature and rainfall are expected to increase, while dramatic decreases in rainfall may lead to severe droughts and plunging agricultural yields in parts of Africa, for example.
Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of 50 centimeters by the year 2050. A sea level rise of this magnitude would flood coastal cities, force people to abandon low-lying islands, and completely inundate coastal wetlands. Diseases like malaria, which at present are primarily found in the tropics, may become more common in the regions of the globe between the tropics and the polar regions, called the temperate zones. For many of the world's plant species, and for animal species that are not easily able to shift their territories as their habitat grows warmer, climate change may bring extinction.What may be the benefit of exaggerated weather conditions for the western United States?

Learning means acquiring knowledge or developing the ability to perform new behaviors. It is common to think of learning as something that takes place in school, but much of human learning occurs outside the classroom, and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to manipulate toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to interact with their parents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for interacting with other children. After they finish school, people must learn to adapt to the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human- service workers need to understand how certain experiences change people's behaviors.
Employers, politicians, and advertisers make use of the principles of teaming to influence the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain.
Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later retrieves knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person's experiences.
There are many forms of learning, ranging from simple to complex. Simple forms of learning involve a single stimulus. A stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch, or taste. In a form of learning known as classical conditioning, people learn to associate two stimuli that occur in sequence, such as lightning followed by thunder. In operant conditioning, people learn by forming an association between a behavior and its consequences (reward or punishment). People and animals can also learn by observation - that is, by watching others perform behaviors. More complex forms of learning include learning languages, concepts, and motor skillsAccording to the passage, what are children NOT usually taught outside the classroom?

Ranked as the number one beverage consumed worldwide, tea takes the lead over coffee in both popularity and production with more than 5 million metric tons of tea produced annually. Although much of this tea is consumed in Asia, European and African countries, the United States drinks it fair share. According to estimates by the Tea Council of the United States, tea is enjoyed by no less than half of the U.S population on any given day. Black tea or green tea - iced, spiced, or instant - tea drinking has spurred a billion - dollar business with major tea produces in Africa and South America and throughout Asia.
Tea is made from the leaves of an evergreen plant, Camellia sinensis, which grows tall and lush in tropical regions. On tea plantation, the plant is kept trimmed to approximately four feet high, and as new buds called flush appear, they are plucked off by hand. Even in today's world of modern agricultural machinery, hand harvesting continues to be preferred method. Ideally, only the top two leaves and bud should be picked. This new growth produces the highest quality tea.
After being harvested, tea leaves are laid out on long drying racks, called withering racks, for 18 to 20 hours. During this process, the tea softens and becomes limp. Next, depending on the type of the tea being produced, the leaves may be crushed or chopped to release flavor, and then steamed to retain their green color, and the fermentation process is skipped. Producing black teas requires fermentation during which the tea leaves begin to darken. After fermentation, black tea is dried in vats to produce its rich brown or black color.
No one knows when or how tea became popular, but legend has it that tea as a beverage was discovered in 2737 B.C. by Emperor Shen Nung of China when leaves from Camellia dropped into his drinking water as it was boiling over a fire. As the story goes, Emperor Shen Nung drank the resulting liquid and proclaimed that the drink to be most nourishing and refreshing. Though this account cannot be documented, it is thought that tea drinking probably originated in China and spread to other parts of Asia, then to Europe, and ultimately to America colonies around 1650.
With about half of the caffeine content as coffee, tea is often chosen by those who want to reduce, but not necessarily eliminate their caffeine intake. Some people find that tea is less acidic than coffee and therefore easier on the stomach. Others have become interested in tea drinking since the National Cancer Institute published its findings on the antioxidant properties of tea. But whether tea is enjoyed for its perceived health benefits, its flavor, or as a social drink, teacups continue to be filled daily with the world's most popular beverage.According to the passage, what is TRUE about the origin of tea drinking?

"The seven-nation Association of Southeast Asian Nations (ASEAN) met September 2, 1996, in Singapore, to discuss how to police the Internet. Although the group agreed on the need to control the explosion of information available on the Internet, it was unable to reach a common policy for regulating access to the global Computer network.
At the end of the three-day meeting, ASEAN government officials and industry experts issued a statement emphasizing the need to block access to Web sites that run “counter to our cherished values, traditions and culture.” ASEAN comprises Brunei, Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam.
The meeting was the first time the Southeast Asian countries had tried to formulate a common approach to the Internet. Many of the ASEAN-member countries were concerned about the dissemination of pornography and antigovernment views over the Internet, the influence and perceived bias of the Western media, and the erosion of Asian values.
The forum, which followed a meeting of ASEAN information ministers earlier in the year, concluded that each country should develop its own regulatory approach to cyberspace. The ASEAN delegates agreed to share information and their experiences with national regulations and “cyberlaws.”
The forum was unable to agree on a regulatory framework for the region because of differing political views regarding censorship. Singapore, which has an estimated 150,000 Web users, is the first ASEAN country to impose regulations on access to the Internet. The city-state requires Internet providers to block access to pornographic sites and regulate political and religious discussion. On the other hand, the Philippines and Thailand support more liberal policies, calling for self- regulation by Internet access providers and minimal government intervention."1.

Water scarcity is fast becoming one of the major limiting factors in world crop production. In many areas, poor agricultural practices have led to increasing desertification and the loss of formerly arable lands. Consequently, those plants species that are well adapted to survival in dry climates are being looked at for an answer in developing more efficient crops to grow on marginally arable lands.
Plants uses several mechanisms to ensure their survival in desert environments. Some involve purely mechanical and physical adaptations, such as the shape of the plant's surface, smaller leaf size, and extensive root systems. Some of the adaptations are related to chemical mechanisms. Many plants, such as cacti, have internal gums and mucilages which give them water-retaining properties. Another chemical mechanism is that of the epicuticular wax layer. This wax layer acts as an impervious cover to protect the plant. It prevents excessive loss of internal moisture. It also protects the plant from external aggression, which can come from inorganic agents such as gases, or organic agents which include bacteria ant plant pets.
Researchers have proposed that synthetic waxes with similar protective abilities could be prepared based on knowledge of desert plants. If successfully developed, such a compound could be used to greatly increase a plant's ability to maintain health in such adverse situations as inadequate water supply, limited fertilizers availability, attacked by pets, and poor storage after harvestingThe word "arable" is closest in meaning to..................

Brunei is one of the smallest countries in the world. Its population is only 25,000 and most of them live in Bandar Seri Begawan (the capital city with the longest name in the world. It is also the richest country in Asia and maybe the richest country in the world because it has a lot of oil and natural gas which it exports to Japan. Every week huge tankers carry oil and gas from the oil-fields of Brunei to Japan. The head of the state in Brunei is Sultan Haji Hassanal Bolkiah. He is the richest man in the world.

New surveys suggest that the technological tools we use to make our lives easier are killing our leisure time. We are working longer hours, taking fewer and shorter vacations (and when we do go away, we take our cell phones, PDAs, and laptops along). And, we are more stressed than ever as increased use of e-mail, voice mail, cell phones, and the Internet is destroying any idea of privacy and leisure.
Since the Industrial Revolution, people have assumed that new labor-saving devices would free them from the burdens of the workplace and give them more time to grow intellectually, creatively, and socially -exploring the arts, keeping up with current events, spending more time with friends and family, and even just ''goofing off''.
But here we are at the start of the 21st century, enjoying one of the greatest technological boom times in human history, and nothing could be further from the truth. The very tools that were supposed to liberate us have bound us to our work and study in ways that were inconceivable just a few years ago. It would seem that technology almost never does what we expect.
In 'the old days', the lines between work and leisure time were markedly clearer. People left their offices at a predictable time, were often completely disconnected from and out of touch with their jobs as they traveled to and from work, and were off-duty once they were home. That is no longer true. In today's highly competitive job market, employers demand increased productivity, expecting workers to put in longer hours and to keep in touch almost constantly via fax, cell phones, e-mail, or other communications devices. As a result, employees feel the need to check in on what is going on at the office, oven on days off. They feel pressured to work after hours just to catch up on everything they have to do. Workers work harder and longer, change their work tasks more frequently, and have more and more reasons to worry about job security.
Bosses, colleagues, family members, lovers, and friends expect instant responses to voice mail and e-mail messages. Even college students have become bound to their desks by an environment in which faculty, friends, and other members of the college community increasingly do their work online. Studies of time spent on instant messaging services would probably show staggering use.
This is not what technology was supposed to be doing for us. Now technologies, from genetic research to the Internet, offer all sorts of benefits and opportunities. But, when new tools make life more difficult and stressful rather than easier and more meaningful - and we are, as a society, barely conscious of it - then something has gone seriously awry, both with our expectations for technology and our understanding of how it should benefit us.Which of the following is true, according to the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
Experts in climatology and other scientists are becoming extremely concerned about the changes to our climate which are taking place. Admittedly, climate changes have occurred on our planet before. For example, there have been several ice ages or glacial periods. These climatic changes, however, were different from the modern ones in that they occurred gradually and, as far as we know, naturally. The changes currently being monitored are said to be the result not of natural causes, but of human activity. Furthermore, the rate of change is becoming alarmingly rapid.
The major problem is that the planet appears to be warming up. According to some experts, this warming process, known as global warming, is occurring at a rate unprecedented in the last 10,000 years. The implications for the planet are very serious. Rising global temperatures could give rise to such ecological disasters as extremely high increases in the incidence of flooding and of droughts. These in turn could have a harmful effect on agriculture.
It is thought that this unusual warming of the Earth has been caused by so-called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of the sun is trapped. This leads to the warming up of the planet.
Politicians are also concerned about climate change and there are now regular summits on the subject, attended by representatives from around 180 of the world’s industrialized countries. Of these summits, the most important took place in Kyotoin Japanin 1997. There it was agreed that the most industrialized countries would try to reduce the volume of greenhouse gas emissions and were given targets for this reduction of emissions.
It was also suggested that more forests should be planted to create so-called sinks to absorb greenhouse gases. At least part of the problem of rapid climate change has been caused by too drastic deforestation. Sadly, the targets are not being met. Even more sadly, global warnings about climate changes are often still being regarded as scaremongering.
According to the passage, agriculture could ____.

Commuters on trains rarely talk to each other and spend their journey reading, sleeping or using their mobile phones, though this is not popular with other passengers. Increasing numbers of people now work at home some days of the week, linked to their offices by computer, a practice called telecommuting.
Cities in both Britain and the US are trying to reduce the number of cars conning into town each day. Some companies encourage car pooling (called car sharing in Britain), an arrangement for people who live and work near each other to travel together. Some Us cities have a public service that helps such people to contact each other, and traffic lanes are reserved for car-pool vehicles. But cars and petrol/gas are cheap in the US, and many people prefer to drive alone because it gives them more freedom. In Britain many cities have park-and-rids schemes, car parks on the edge of the city from which buses take drivers into the centre.The passage mentions that many Americans are willing to travel a long distance to work in order to be able to live in .....................

New surveys suggest that the technological tools we use to make our lives easier are killing our leisure time. We are working longer hours, taking fewer and shorter vacations (and when we do go away, we take our cell phones, PDAs, and laptops along). And, we are more stressed than ever as increased use of e-mail, voice mail, cell phones, and the Internet is destroying any idea of privacy and leisure.
Since the Industrial Revolution, people have assumed that new labor-saving devices would free them from the burdens of the workplace and give them more time to grow intellectually, creatively, and socially -exploring the arts, keeping up with current events, spending more time with friends and family, and even just ''goofing off''.
But here we are at the start of the 21st century, enjoying one of the greatest technological boom times in human history, and nothing could be further from the truth. The very tools that were supposed to liberate us have bound us to our work and study in ways that were inconceivable just a few years ago. It would seem that technology almost never does what we expect.
In 'the old days', the lines between work and leisure time were markedly clearer. People left their offices at a predictable time, were often completely disconnected from and out of touch with their jobs as they traveled to and from work, and were off-duty once they were home. That is no longer true. In today's highly competitive job market, employers demand increased productivity, expecting workers to put in longer hours and to keep in touch almost constantly via fax, cell phones, e-mail, or other communications devices. As a result, employees feel the need to check in on what is going on at the office, oven on days off. They feel pressured to work after hours just to catch up on everything they have to do. Workers work harder and longer, change their work tasks more frequently, and have more and more reasons to worry about job security.
Bosses, colleagues, family members, lovers, and friends expect instant responses to voice mail and e-mail messages. Even college students have become bound to their desks by an environment in which faculty, friends, and other members of the college community increasingly do their work online. Studies of time spent on instant messaging services would probably show staggering use.
This is not what technology was supposed to be doing for us. Now technologies, from genetic research to the Internet, offer all sorts of benefits and opportunities. But, when new tools make life more difficult and stressful rather than easier and more meaningful - and we are, as a society, barely conscious of it - then something has gone seriously awry, both with our expectations for technology and our understanding of how it should benefit us.
According to the first three paragraphs, technological tools that were designed to make our lives easier .......................

Learning means acquiring knowledge or developing the ability to perform new behaviors. It is common to think of learning as something that takes place in school, but much of human learning occurs outside the classroom, and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to manipulate toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to interact with their parents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for interacting with other children. After they finish school, people must learn to adapt to the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human- service workers need to understand how certain experiences change people's behaviors.
Employers, politicians, and advertisers make use of the principles of teaming to influence the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain.
Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later retrieves knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person's experiences.
There are many forms of learning, ranging from simple to complex. Simple forms of learning involve a single stimulus. A stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch, or taste. In a form of learning known as classical conditioning, people learn to associate two stimuli that occur in sequence, such as lightning followed by thunder. In operant conditioning, people learn by forming an association between a behavior and its consequences (reward or punishment). People and animals can also learn by observation - that is, by watching others perform behaviors. More complex forms of learning include learning languages, concepts, and motor skillsAccording to the passage, the study of learning is important in many fields due to :

Water scarcity is fast becoming one of the major limiting factors in world crop production. In many areas, poor agricultural practices have led to increasing desertification and the loss of formerly arable lands. Consequently, those plants species that are well adapted to survival in dry climates are being looked at for an answer in developing more efficient crops to grow on marginally arable lands.
Plants uses several mechanisms to ensure their survival in desert environments. Some involve purely mechanical and physical adaptations, such as the shape of the plant's surface, smaller leaf size, and extensive root systems. Some of the adaptations are related to chemical mechanisms. Many plants, such as cacti, have internal gums and mucilages which give them water-retaining properties. Another chemical mechanism is that of the epicuticular wax layer. This wax layer acts as an impervious cover to protect the plant. It prevents excessive loss of internal moisture. It also protects the plant from external aggression, which can come from inorganic agents such as gases, or organic agents which include bacteria ant plant pets.
Researchers have proposed that synthetic waxes with similar protective abilities could be prepared based on knowledge of desert plants. If successfully developed, such a compound could be used to greatly increase a plant's ability to maintain health in such adverse situations as inadequate water supply, limited fertilizers availability, attacked by pets, and poor storage after harvestingThe word "it" refers to......................
