For hundreds of years, giving flowers have been a social means of communication. In the United States, flowers are often given during rites of passage, for commemorating special occasions or as a heartfelt gift between loved ones and friends. Flower gifting also occurs in most countries around the world. However, the meanings and traditions often vary.
While students traditionally gave their favorite teacher an apple in past years, in China, teachers are given flowers. Peonies are by far the  flower most often  given  in  China. They are also quite popularly used for weddings. Strangely, potted plants are not considered a pleasant gift among Asian cultures. The people believe that like a plant confined by a pot, the gift  symbolizes a binding or restriction.
In Russia, in lieu of giving birthday presents, the guest of honor receives a single flower or an unwrapped bouquet. Floral arrangements or baskets are not given. Russians celebrate a holiday known as Woman's Day. Traditional gifts include red roses, hyacinths or tulips. When   there is a funeral or other occasion where someone wishes to express sympathy, carnations, lilies or roses are given in circular configurations, which signify the transition of birth, life and death to   rebirth. In this instance, the color of choice is commonly yellow. For joyous occasions, arrangements and bouquets generally contain an odd number of flowers.
In the times of ancient Rome, brides carried flowers to scare away evil spirits and encourage fertility. The Dutch believed that flowers were food for the soul. When invited to someone's home in Great Britain, it is tradition to bring a gift of flowers. All types are acceptable except white lilies, which are usually seen at funerals. Unlike the United States, red roses are a symbol of love.
Flowers are generally gifted in odd numbered increments regardless of the occasion. However, the Brits also have superstitions regarding the number 13, so the number is avoided.
In the southern region of the continent, flowers are traditionally given during Christmas. Egyptians are much more conservative and restrict flower gifting to funerals and weddings. While certain flowers may have significant meanings for some, flowers in Las Vegas and across the United States flowers are an accepted gift for any reason desired.

She wants to be a singer; you think she should go for a long–term career with job security and eventually retire with a good pension. But a new report suggests that in fact she’s the practical one. Why do parents make terrible career advisers?
Today’s 14 and 15–year–olds are ambitious. They are optimistic about their prospects, but their career ideas are rather vague. Although 80% of them have no intention of following in their parents’ footsteps, 69% still turn to their parents for advice. They look at their working future in a different way to their parents.
A job for life is not in their vocabulary; neither is a dead–end but secure job that is boring but pays the bills. Almost half the boys surveyed expected that their hobbies would lead them into the right sort of job, while most girls seemed determined to avoid traditionally female careers such as nursing.
In the past, this might have counted as bad news. Certainly when I was 15, my guidance counsellors were horrified at my plans to become a writer. I’m glad I didn’t change my plans to suit them. Even so, their faith in rigid career paths was well–founded. In those days, that was the way to get ahead.
But the world has changed. The global economy is not kind to yesterday’s diligent and dependable worker. The future belongs to quick–thinking people who are resourceful, ambitious and can take the initiative. This means that a 14–year–old who sees her working future as a kind of adventure, to be made up as she goes along is not necessarily being unrealistic.
However, she has to have the training and guidance to help her develop the right skills for today’s market; not the rigid preparation for a workplace that disappeared twenty years ago. Many young people are very aware of the pitfalls of the flexible workplace; they understand that redundancy, downsizing and freelancing are all part of modern working life, but no one is telling them how they might be able to turn the new rules of the employment game to their advantage. This is what they need to know if they are to make a life for themselves.

So what is to be done? A good first step would be to change the way in which schools prepare young people for adult life. The education system is becoming less flexible and more obsessed with traditional skills at just the time that the employment market is going in the opposite direction.
Accurate, up–to–date information on new jobs and qualifications can help guidance counsellors to help their students. Young people need solid information on the sort of training they need to pursue the career of their dreams. Also, a little bit of encouragement can go a long way. If nothing else, a bit of optimism from an adult can serve as an antidote to the constant criticism of teenagers in the press.
What, then, can we as parents do to help them? The best thing is to forget all the advice that your parents gave you, and step into your teenager’s shoes. Once you’ve done that, it’s easier to see how important it is that they learn how to be independent, resourceful and resilient. Give them the courage to follow their dreams –however odd they might sound right now. In a world that offers economic security to almost no one, imagination is a terrible thing to waste.

Do you feel like your teenager is spending most of the day glued to a phone screen? You're not too far off. A new survey from the Pew  Research Center reveals the  surprising  ways that technology intersects with teen friendships —  and the results show that 57  percent  of teens have made at least one new friend online. Even more surprisingly, only 20 percent of those digital friends ever meet in person.
While teens do connect with their friends face-to-face outside of school, they spend 55 percent of their day texting with friends, and only 25 percent of teens are spending actual time with their friends on a daily basis (outside of school hallways). These new forms of communication are key in maintaining friendships day-to-day — 27 percent of teens instant message their friends every day, 23 percent connect through social media every day, and 7 percent even video chat daily. Text messaging remains the main form of communication — almost half of survey respondents say it's their chosen method of communication with their closest friend.
While girls are more likely to text with their close friends, boys are meeting new friends (and maintaining friendships) in the gaming world-89 percent play with friends they know, and  54 percent play with online-only friends. Whether they're close with their teammates or not, online garners say that playing makes them feel "more connected" to friends they know, or garners they've never met.
When making new friends, social media has also become a major part of the teenage identity-62 percent of teens are quick to share their social media usernames when connecting with a new friend (although 80 percent still consider their phone number the best method of contact). Despite the negative consequences-21 percent of teenage users feel worse about their  lives because of posts they see on social media — teens also have found  support  and  connection through various platforms. In fact, 68  percent of  teens received support during a challenging time  in their lives via social media platforms.
Just as technology has become a gateway for new friendships, or a channel to  stay  connected with current friends, it can also make a friendship breakup more public. The study reveals that girls are more likely to block or unfriend former allies, and 68 percent of all teenage  users report experiencing "drama among their friends on social media."

According to the passage, what percentage of teens spend actual time with their friends?

Translators and interpreters for tech jobs of the future are expected to be one of the fastest growing occupations in the nation, according to a just released survey by Vietnamworks. Almost all positions for programmers, application developers, database and network administrators, engineers, designers, architects, scientists, technicians, and tech support will require bilingual or multilingual fluency. In just the last two years the demand for tech professionals with foreign language skills has increased more than two and one-half fold, said the survey, and the uptick shows no signs of abating anytime soon. Roughly 400,000 jobs are expected to open for interpreters (who focus on spoken language) and translators (who focus on written language) in the tech segment, between 2017 and 2020, says Tran Anh Tuan. Tuan, who works for the Centre for Forecasting Manpower Needs and Labour Market Information in Ho Chi Minh City doesn't include other industries in his prediction,
which are also recruiting ferociously for more people with these same language skills.
While that claim might seem a bit overblown (and amounts to little more than a guess by Tuan), it is clear that innovative technologies like robotics, 3D printing, drones, artificial intelligence   and virtual reality will create major upheavals in all sorts of labor markets, not just technology over     the next few years. In the last month alone, most every job posted on employment websites throughout Vietnam included the word bilingual. Far higher salaries go to people who work in high    tech positions and can speak a foreign language such as English in addition to Vietnamese, says Tran Quang Anh from the Posts and Telecommunications Institute of Technology.
Unfortunately, the surveys show that most graduating Vietnamese students are unable to do more than understand a few basic phrases of foreign languages, and practically none of them  can speak any foreign language coherently, The good paying jobs with high salaries and benefits are only available to translators and interpreters who specialize in high tech jobs, says Anh. But it's    not just English— graduates are needed with fluency in middle eastern languages like  Arabic, Farsi and Pashto (Afghani) as well as German, Japanese and Korean to name just a few. Spanish is  also in high demand in Vietnam, primarily because it is the second most common language in the US after English.
A recent tech expo in Hanoi sponsored by Vietnamworks and the Navigos Group attracted nearly 4,000 young tech graduates and recruiters from 14 leading companies looking to fill job  vacancies with skilled bilingual workers. The job applicants were young and industrious, said the recruiters. However, missing were candidates with the requisite language skills and most lacked  basic 'soft skills' such as written and verbal communication abilities to effectively communicate  even in their native Vietnamese language.
Notably, the recruiters said they considered language abilities and soft skills just as, if not more important, than academic ability. Yet virtually all the prospective academically qualified employees lacked even the most basic of interpersonal communication abilities.

Did you ever watch a video on the Internet? Maybe you used YouTube. YouTube is a Website where people can share their video. Today, YouTube is an important part of the Internet. However, that wasn’t always true.
YouTube started with a young man named Jawed Karim and two friends. One day, Karim was on the Internet. He wanted information about the 2004 tsunami in Southeast Asia. He found news stories about it, but he couldn't find any videos. This gave Karin an idea. He wanted to help people put video on the Internet. Karim told his friends about this idea. Together, they created a company - YouTube.
YouTube become a global success. Millions of people around the world Visited the Website. It was clear to Google, another Internet company, that YouTube had a lot of value. Google made a deal. It bought YouTube for $1.65 billion. As a result, YouTube investors and its employees made a lot of money. The three friends who started YouTube were very big investors. Therefore, they made an enormous amount of money.
Karim became very rich, and he continued to work toward his PhD. There was something else he wanted to do. He wanted to help young people go into business. He used money and experience to start a new company called Youniversity Ventures. This company helps young people who have good business ideas. It gives them advice and money to start Internet businesses. Milo is one business that students started with the help of Youniversity Ventures.
Milo is a shopping Website. It helps people find products in stores near their homes. Another example is AirBoB. This Web site helps people find for video conferences. People in different places can use this site to have business meetings.
Karim has some advice for students who want to start business. First, find a successful company. Do a lot of research about the company and the top people in the company. There, copy the way they do things. For students who wants to start Interner business, Karim is probably a very good example to copy.

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.

“When a snow leopard stalks its prey among the mountain walls, it moves softly, slowly,” explains Indian biologist Raghunandan Singh Chundawat, who has studied the animal for years. “If it knocks a stone loose, it will reach out a foot to stop it from falling and making noise.” One might be moving right now, perfectly silent, maybe close by. But where? And how many are left to see?

Best known for its spotted coat and long distinctive tail, the snow leopard is one of the world’s most secretive animals. These elusive cats can only be found high in the remote, mountainous regions of central Asia. For this reason, and because they hunt primarily at night, they are very rarely seen.

Snow leopards have been officially protected since 1975, but enforcing this law has proven difficult. Many continue to be killed for their fur and body parts, which are worth a fortune on the black market. In recent years, though, conflict with local herders has also led to a number of snow leopard deaths. This is because the big cats kill the herders’ animals, and drag the bodies away to eat high up in the mountains.

As a result of these pressures, the current snow leopard population is estimated at only 4,000 to 7,000, and some fear that the actual number may already have dropped below 3,500. The only way to reverse this trend and bring these cats back from near extinction, say conservationists, is to make them more valuable alive than dead.

Because farming is difficult in Central Asia’s cold, dry landscape, traditional cultures depend mostly on livestock (mainly sheep and goats) to survive in these mountainous regions. At night, when snow leopards hunt, herders’ animals are in danger of snow leopard attacks. Losing only a few animals can push a family into desperate poverty. “The wolf comes and kills, eats, and goes somewhere else,” said one herder, “but snow leopards are always around. They have killed one or two animals many time. Everybody wanted to finish this leopard.”

To address this problem, local religious leaders have called for an end to snow leopard killings, saying that these wild animals have the right to exist peacefully. They’ve also tried to convince people that the leopards are quite rare and thus it is important to protect them. Financial incentives are also helping to slow snow leopard killings. The organization Snow Leopard Conservancy–India has established Himalayan Homestays, a program that sends visitors to the region to herders’ houses. For a clean room and bed, meals with the family, and an introduction to their culture, visitors pay about ten U.S. dollars a night. Having guests once every two weeks through the tourist season provides the herders with enough income to replace the animals lost to snow leopards. In addition, Homestays helps herders build protective fences that keep out snow leopards. The organization also conducts environmental classes at village schools and trains Homestays members as nature guides, available for hire. In exchange, the herders agree not to kill snow leopards.

In Mongolia, a project called Snow Leopard Enterprises (SLE) helps herder communities earn extra money in exchange for their promise to protect the endangered cat. Women in Mongolian herder communities make a variety of products—yarn for making clothes, decorative floor rugs, and toys—using the wool from their herds. SLE buys these items from herding families and sells them abroad. Herders must agree to protect the snow leopards and to encourage neighbors to do the same.

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:
Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.
Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.
The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.
The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.
The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the  earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.

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:
Diversity is a hallmark of life, an intrinsic feature of living systems in the natural world. The demonstration and celebration of this diversity is an endless rite. Look at the popularity of museums, zoos, aquariums and botanic gardens. The odder the exhibit, the more different it is from the most common and familiar life forms around us, the more successful it is likely to be. Nature does not tire of providing oddities for people who look for them. Biologists have already formally classified 1.7 million species. As many as 30 to 40 million more may remain to be classified. (1)
Most people seem to take diversity for granted. If they think about it at all they assume it exists in endless supply. Nevertheless, diversity is endangered as never before in its history. Advocates of perpetual economic growth treat living species as expendable. As a result an extinction crisis of unprecedented magnitude is under way. Worse yet, when diversity needs help most, it is neglected and misunderstood by much of the scientific community that once championed it. (2)
Of the two great challenges to the legitimacy of this diversity, the familiar one comes primarily from economists. Their argument, associated with such names as Julian Simon, Malcolm McPherson and the late Herman Kahn, can be paraphrased: "First, if endangered species have a value as resources - which has been greatly exaggerated - then we should be able to quantify that value so that we can make unbiased, objective decisions about which species, if any, we should bother to save, and how much the effort is worth. Secondly, the global threat to the diversity of species, particularly in the tropics, has been overestimated. Thirdly, we have good substitutes for the species and ecosystems that are being lost, and these substitutes will nullify the damage caused by the extinctions". (3)
The structure of the argument seems to me to be identical in form to that of an old joke from the American vaudeville circuit. One elderly lady complained to another about her recent vacation at a resort in the Catskill Mountains in New York State. "The food was terrible", she moaned. "Pure poison, I couldn't eat a bite. And the portions were so tiny!" (4)
Species may be valuable, but not especially so, and the threat to them has been exaggerated. But this does not matter anyway, say the economists, because we can replace any species that vanishes.(5) 
It is not clear how much of an impact this argument has on the informed public, but it has certainly provoked an outcry among scientific conservationists. It has set the terms for, and dominated, most of the pro-diversity literature of the past few years, making it a literature of response, thus limiting its scope and creative force.

What point is the writer trying to make about the economists' arguments by including the joke in paragraph 4?

As the twentieth century began, the importance of formal education in the United States increased. The frontier had mostly disappeared and by 1910 most Americans lived in towns and cities. Industrialization and the bureaucratization of economic life combined with a new emphasis upon credentials and expertise to make schooling increasingly important for economic and social mobility. Increasingly, too, schools were viewed as the most important means of integrating immigrants into American society.
The arrival of a great wave of southern and eastern European immigrants at the turn of the century coincided with and contributed to an enormous expansion of formal schooling. By 1920 schooling to age fourteen or beyond was compulsory in most states, and the school year was greatly lengthened. Kindergartens, vacation schools, extracurricular activities, and vocational education and counseling extended the influence of public schools over the lives of students, many of whom in the larger industrial cities were the children of immigrants. Classes for adult immigrants were sponsored by public schools, corporations, unions, churches, settlement houses, and other agencies.
Reformers early in the twentieth century suggested that education programs should suit the needs of specific populations. Immigrant women were once such population. Schools tried to educate young women so they could occupy productive places in the urban industrial economy, and one place many educators considered appropriate for women was the home.
Although looking after the house and family was familiar to immigrant women, American education gave homemaking a new definition. In preindustrial economies, homemaking had meant the production as well as the consumption of goods, and it commonly included income-producing activities both inside and outside the home, in the highly industrialized early-twentieth-century United States, however, overproduction rather than scarcity was becoming a problem. Thus, the ideal American homemaker was viewed as a consumer rather than a producer. Schools trained women to be consumer homemakers cooking, shopping, decorating, and caring for children "efficiently" in their own homes, or if economic necessity demanded, as employees in the homes of others. Subsequent reforms have made these notions seem quite out-of-date.

According to the passage, one important change in United States education by the 1920's was that     .
