All the different plants and animals in a natural community are in a state of balance. This balance is achieved by the plants and animals interacting (1) _______ each other and with their non-living surroundings. An example of a natural community is a woodland, and a woodland is usually dominated by a particular species of plant, such as the oak tree in an oak wood. The oak tree in this example is therefore called the dominant species but there are also many other types of plants, from brambles, bushes, and small trees to mosses, lichens and algae (2) __________ on tree trunks and rocks. The plants of a community are the producers: they use carbon dioxide, oxygen, nitrogen to build up their tissues using energy in the form of sunlight. The plant tissues form food for the plant-eating animals (herbivores) (3) _______ are in turn eaten by flesh-eating animals (carnivores). Thus, plants produce the basic food supply for all the animals of a community. The animals themselves are the consumers, and are either herbivores or carnivores. Examples of herbivores in a woodland community are rabbits, deer, mice and snails, and insects such as aphids and caterpillars. The herbivores are sometimes eaten by the carnivores. Woodland carnivores are of all sizes, from insects such as beetles and lacewings to animals such as owls, shrews and foxes. Some carnivores feed on herbivores, some feed on the smaller carnivores, (4) _______ some feed on both: a tawny owl will eat beetles and shrews as well as voles and mice. These food relationships between the different members of the community are known as food chains or food (5) ______. All food chains start with plants. The links of the chain are formed by the herbivores that eat the plants and the carnivores that feed on the herbivores. There are more organisms at the base of the food chain than at the top; for example, there are many more green plants than carnivores in a community

Set aside time each day Most of us can find 15 minutes or half an hour each day for some specific regular activity. It may be a free period or a regular wait, stay in the queue for a bus or meal - even while eating breakfast. One famous surgeon always made it a rule to spend at least 15 minutes on general reading before he went to sleep each night. Whether he went to bed at 10:00 p.m or 2:30 a.m. made no difference. Even if you cannot keep to this kind of discipline, it is a good idea to make sure you always have a general interest book in your pocket. Don’t forget it should be a book which entertains you and the English must not be too difficult for you. Checking your progress through pacing Nearly all speed reading courses have a "pacing element - some timing device which lets the student know how many words a minute he is reading. You can do this simply by looking at your watch every 5 or 10 minutes and noting down the page number you have reached. How do you know when 5 minutes have passed on your watch if you are busy reading the book? Well, this is difficult at first. A friend can help by timing you over a set period. Pace yourself every three or four days, always with the same kind of easy, general interest book. You should soon notice your habitual w. p. m rate creeping up. Check comprehension Obviously there is little point in increasing your w. p. m rate if you do not understand what you are reading. When you are consciously trying to increase your reading speed, stop after every chapter (if you are reading a novel) or every section or group of ten or twelve pages (if it is a textbook) and ask yourself a few questions about what you have been reading. If you find you have lost the thread of the story, or you cannot remember clearly the details of what was said, re-read the section or chapter. “Lightening speed” exercise Take 4 or 5 pages in the general interest book you happen to be reading at the time. Read them as fast as you possibly can. Do not bother about whether you understand or not. Now go back and read them at what you feel to be your normal w. p. m rate, the rate at which you can comfortably understand. After a “lightening speed” read through (probably around 6 w. p. m) you will usually find that your normal speed has increased -  perhaps by as much as 50 -100 w. p. m.
1. The passage recommends setting aside for reading practice ____

Most Americans still get married at some point in their lives, but even that group is shrinking. Among current generations of adult American - starting with those bom in 1920s - more than 90 percent have married or will marry at some point in their lives. However, based on recent patterns of marriage and mortality, demographers calculate that a growing share of the younger generations are postponing marriage for so long that an unprecedented number will never marry at all.

More Americans are living together outside of marriage. Divorced and widowed people are waiting longer to remarry. An increasing number of single women are raising children. Put these trends together with our increasing life expectancy, and the result is inevitable. Americans are spending a record low proportion of their adult lives married.

Married rates for unmarried men and women have dropped from their post-195Os high to record lows. Part of this fall is due to the change in the age at which people first marry. The median age at first marriage is the age by which half the men or women who will ever marry have done so. It fell almost continuously from the time it was first measured, in 1890, at 22.0 years for women and 26.1 for men, to a low of 20.3 for women and 22.6 for men between 1947 and 1962. Since then, it has risen at a rapid pace, to a record high for 23.8 for women and 26.2 for men in 1994.

The length of time between marriages is also increasing, and more divorced people are choosing not to remarry. In 1990, divorced men had waited an average of 3.8 years before remarrying, and divorced women had waited an average of 3.5 years, an increase of more than one year over the average interval in 1970.

Data on cohabitation and unmarried childbearing suggest that marriage is becoming less relevant to Americans. 2.8 million of the nation's households are unmarried couples, and one-third of them are caring for children, according to the Census Bureau

Read the following passage and choose the best answer (A, B, C, D):
The International Ecotourism Society (TIES), a non-profit organization committed to promoting sustainable tourism, states that ecotourism unites conservation and communities with sustainable travel. With that being said, they offer six core principles of ecotourism that vacationers should follow: minimize impact, build environmental and cultural awareness and respect, provide positive experiences for both visitors and hosts, provide direct financial benefits for conservation, provide financial benefits and empowerment for local people, and raise sensitivity to host countries’ political, environmental, and social climate. Ecotourism offers the opportunity to help protect and maintain our planet. Beginning with responsible travel, sustainable tourism promotes green practices such as recycling and using organic products. There are also many environmental programs and initiatives made available so that people can get involved with sustainability. For example, in Kenya, tourists can get involved with the Basecamp Foundation, which has a monitoring program for big cats and elephants. These kinds of experiences try to demonstrate the positive impact of tourism and teach tourists about the significance of maintaining the environment. However, the simple act of being a tourist in a fragile, natural area helps a great deal, as the money spent there assists in raising funds to protect those areas for generations. Sustainable tourism supports local communities by allowing their economy to grow. Tourism alone employs a large number of local staff. This in turn empowers communities to fight against poverty and encourages the support of local events, festivals, and organizations. As a result the community and its local businesses thrive.  Not only is ecotourism an environmentally fun experience, but it’s also educational. By embarking on an ecotourism vacation, people gain an awareness and understanding of the social and economic conditions of the place they visit. In addition, vacationers learn to appreciate the area’s environment through conservation and also to respect the culture of the local people. While tourists are normally unaware of a country’s poverty or ill conditions, ecotourism strives to expose tourists to the realities of these areas. Ecotourism is a new holiday experience that mixes together vacation fun with conservation and education. Sustainable tourism creates environmentally aware individuals and helps develop their appreciation of nature and local culture. Not only do vacationers go home with new knowledge, but also a worthwhile experience.

Read the following passage and choose the best answer (A, B, C, D):
The climate crisis is poised to deliver a severe blow to America’s most threatened animals, with a new study finding that almost every species considered endangered is vulnerable in some way to global heating. Of the 459 animal species listed as endangered by the US government, researchers found that all but one, or 99.8%, have characteristics that will make it difficult for them to adapt to rising temperatures. The California condor, once close to being completely wiped out, faces increased risk of contamination in hotter conditions. Key deer, found only in the Florida Keys, face losing habitat to the rising seas. Whole classes of animals including amphibians, mollusks and arthropods are sensitive to the greatest number of climate-related threats, such as changes in water quality, shifting seasons and harmful invasive species that move in as temperatures climb. Mammals, such as the north Atlantic right whale and Florida panther, also face increased hardships, albeit on fewer fronts than amphibians, mollusks and arthropods.  Despite the overwhelming peril faced by America’s endangered species due to the climate crisis, the report, published in Nature Climate Change, found a patchy response from the US government. Federal agencies consider just 64% of endangered species to be threatened by the climate crisis, while just 18% of listed species have protection plans in place. Astrid Caldas, a study co-author and a climate scientist at the Union of Concerned Scientists said: “While agencies have increasingly listed climate change as a growing threat to species whose survival is already precarious, many have not translated this concern into tangible actions, meaning a significant protection gap still exists.” Nearly half of Australian species are threatened by the climate crisis, researchers have found. A spokesman for the US Fish and Wildlife Service, which oversees the endangered species list, said that while a species may be sensitive to changes in the climate, this sensitivity may not be so severe as to warrant being put on the list. “Our process for determining this looks at five factors: threats to a species’ habitat, overutilization, disease or predation, existing regulatory mechanisms, and other factors that may affect its continued existence,” he said. “Through this scientifically rigorous process we examine and account for the effects of climate change.

Read the following passage and choose the best answer (A, B, C, D):
For nearly all of human history, there haven’t been that many of us. Around the year zero, Earth’s population is estimated to have been 190 million. A thousand years later, it was probably around 250 million. Then the Industrial Revolution happened, and human population went into overdrive. It took hundreds of thousands of years for humans to hit the 1 billion mark, in 1800. We added the next billion by 1928. In 1960, we hit 3 billion. In 1975, 4 billion. That sounds like the route to an overpopulation apocalypse, right? To many midcentury demographers, futurists, and science fiction writers, it certainly predicted one. Extending the timeline, they saw a nightmarish future ahead for humanity: human civilizations constantly on the brink of starvation, desperately crowded under horrendous conditions, draconian population control laws imposed worldwide. Stanford biologist Paul Ehrlich wrote in his best-selling book, “In the 1970’s, hundreds of millions of people will starve to death” because of overpopulation. None of that ever came to pass. The world we live in now, despite approaching a population of nearly 8 billion, looks almost nothing like the one doomsayers were anticipating. Starting in the 19th century in Britain and reaching most of the world by the end of the 20th century, birthrates plummeted — mostly because of women’s education and access to contraception, not draconian population laws. In wealthy societies where women have opportunities outside the home, the average family size is small; in fact, it’s below replacement level. Called the demographic transition, it is one of the most important phenomena for understanding trends in global development.  There’s still significant debate among population researchers about the extent of the sea change in population trends. Researchers disagree on whether global populations are currently on track to start declining by midcentury. There’s also disagreement on what the ideal global population figure would be, or whether it’s morally acceptable to aim for such a figure. While academic research seeks to nail down these questions, it’s important to be clear what is consensus among researchers. Our projections around population are used to make global health and development policy. They’re critical for planning, especially about climate change. Fears of overpopulation sometimes turn into hostility to immigrants, those who choose to have large families, and countries in an earlier stage of their population transition. Having an informed conversation about population is crucial if we are to get humanity’s future right.

“Where is the university?” is a question many visitors to Cambridge ask, but no one can give them a clear answer, for there is no wall to be found around the university. The university is the city. You can find the classroom buildings, libraries, museums and offices of the university all over the city. And most of its members are the students and teachers or professors of the thirty- one colleges. Cambridge is already a developing town long before the first students and teachers arrived 800 years ago. It grew up by the river Granta, as the Cam was once called. A bridge was built over the river as early as 875.
In the fourteenth and fifteenth centuries, more and more land was used for college buildings. The town grew faster in the nineteenth century after the opening of the railway in 1845. Cambridge became a city in 1951 and now it has the population of over 100000. Many young students want to study at Cambridge. Thousands of people from all over the world come to visit the university town. It has become a famous place all around the world.

After which year did the town really begin developing?

In the United States, presidential elections are held in years evenly divisible by four (1888, 1900, 1964, etc.). Since 1840, American presidents elected in years ending with zero have died in office, with one exception. William H. Harrison, the man who served the shortest term, died of pneumonia only several weeks after his inauguration.
Abraham Lincoln was one of four presidents who were assassinated. He was elected in 1860, and his untimely death came just five years later. James Garfield, a former Union army general from Ohio, was shot during his first year in office (1881) by a man to whom he wouldn’t give a job. While in his second term of office (1901), William McKinley, another Ohioan, attended the Pan-American Exposition in Buffalo, New York. During the reception, he was assassinated while shaking hands with some of the guests. John F. Kennedy was assassinated in 1963 in Dallas only three years after his election.
Three years after his election in 1920, Warren G, Harding died in office. Although it was never proved, many believe he was poisoned. Franklin Roosevelt was elected four times (1932, 1936, 1940 and 1944), the only man to serve so long a term. He had contracted polio in 1921 and eventually died of the illness in 1945.
Ronald Reagan, who was elected in 1980 and reelected four years later, suffered an assassination attempt but did not succumb to the assassin’s bullets. He was the first to break the long chain of unfortunate events. Will the candidate in the election of 2020 also be as lucky?

Minister of Industry and Trade Tran Tuan Anh said over the past 50 years of co- operation and development, besides security, political, cultural and social cooperation, ASEAN has been focusing on economic co-operation through the establishment of the ASEAN Economic Community.  ASEAN member states have carried out such activities as one-stop-shop custom procedure, mutual recognition arrangements (MRAs) on electricity, rubber, processed food, pharmaceuticals, etc. Statistics by the Ministry of Industry and Trade reveals when Vietnam joined AFTA in 1996, the country’s two-way trade turnover with other countries in the bloc was only some 5.9 billion USD. In 2018, this number increased by more than 9.5 times and reached about 56.3 billion USD. In the first six months of 2019, Vietnam’s exports to ASEAN reached 13.067 billion USD, up 6.7 percent year-on-year.  Notably, the introduction of the AEC marked a new integration step of ASEAN economies with a goal of building a competitive, dynamic and innovative ASEAN. Tran Thanh Hai, deputy head of the Import-Export Department under the Ministry of Industry and Trade, said that entering the ASEAN market, many Vietnamese products have had positive changes and become more competitive. For example, Vietnam used to acquire shrimp cultivation methods from other countries, such as Thailand in the past. However, it has made it to the list of biggest shrimp exporters in the world. On the other hand, having joined the AEC, enterprises now pay more attention to product quality, including technical standards.  Even when Vietnam enters a new era of integration with global-scale free trade agreements already put on the table for negotiation, the role of ASEAN Economic Community is still significant. AEC lays a firm foundation for Vietnam to continue its journey of global integration, insiders said.

It was not until 1920 when women finally got the right to vote. This was 50 years after the male ex-slaves of the United States were gaining the right to vote. Though women had already right to vote, the stereotypes made women be restricted in their actions. Would you believe that women who were doing the same job as men were getting paid only the 60% of what man wear to paint? In fact, they were getting paid differently for doing exactly the same work. In the 1930s there was not a huge choice of workplace for women. They could still work as secretaries, nurses, teachers and social workers. These kinds of professions were considered typically female professions and were paid much less than other professions. That kind of restrictions themed unbearable for some women. They rejected to go on with this rules anymore. They changed their hair color, style appearance and started to fight against the existing stereotypes. Those women were named in history as “flappers”. The first time in history they started wearing short skirts which were something shocking to the society. They also started driving cars, drinking alcohol, which raised a huge boom. Those kinds of things were considered “Non-feminine”. Actions of flappers were accepted as radical, though they had their influence on the society finally. The heavy restrictions started disappearing every year and today we have what we have. For a very long time, women were considered inferior to men. However, the role of a woman in society has significantly changed during recent decades. Today the importance of women in the society is beyond any suspicion. In today’s world, women with their ambitions, intelligence and strength have proved that the word “inferior” has nothing in common with their gender.

Globalization can be seen as increased economic, cultural and technological exchange between countries. Examples might be McDonald's in Calcutta and Japanese motor technology in Britain. Many international organizations are pro-globalization, while many others are anti- ones. The main organizations against globalization are the environmental organizations, such as Friends of the Earth and reenpeace, who put forward the belief that globalization harms the environment. In general, these organizations blame global corporations for global warning and the depletion of natural resources. The most obvious is oil and gas, but there are others such as tropical rainforests, which are cut down for timber, and the resources of the sea, which may be affected by pollution. Organizations which represent developing countries, including international aid agencies such as Oxfam, are also against globalization. They are concerned that the global organizations, such as the International Monetary Fund (IMF) and the World Bank, are not doing enough to help the poor and indeed, may be adding to their problems. Some are critical of the World Trade Organization (WTO). They argue that the WTO is making difficult for poor countries to protect and build their own industries. On the contrary, many organizations are in favor of globalization. Perhaps the most important one is the WTO. This organization was set up in 1995 and has 123 member countries. It administers the rules of international trade agreed by its member countries. The WTO's rules make it difficult for a country to favor their own industry over imports from other countries. The WTO argues that the growth of trade between countries increases the wealth of everyone. Trade allows those who can produce goods most cheaply to do so, thus giving everyone the best possible price. Another pro-globalization organization is IMF. This was established after World War II in 1946. It aims to promote international cooperation on finance and provide temporary help for countries suffering financial problems. The IMF has 182 member countries. Finally, the United Nations, which was established after the Second World War, has become a promoter of globalization. It aims to  promote a shared set of values in the areas of labour standards, human rights and environmental practices between the UN and the business community.

Books which give instructions on how to do things are very popular in the United States today. Thousands of these How-to books are useful. In fact, there are about four thousand books with titles that begin with the words “How to”. One book may tell you how to earn more money. Another may tell you how to save or spend it and another may explain how to give your money away.

Many How-to books give advice on careers. They tell you how to choose a career and ‘now to succeed in it. If you fail, however, you can buy the book ” How to Turn Failure into Success”. If you would like to become very rich, you can buy the book “How to Make a Millionaire”. If you never make any money at all, you may need a book called “How to Live on Nothing”.

One of the most popular types of books is one that helps you with personal problems. If you want to have a better love of life, you can read “How to Succeed in Love every Minute of Your Life”. If you are tired of books on happiness, you may prefer books which give step-by-step instructions on how to redecorate or enlarge a house.

Why have How-to books become so popular? Probably because life has become so complex. Today people have far more free time to use, more choices to make, and more problems to solve. How-to books help people deal with modern life.

Read the following passage and choose the best answer (A, B, C, D):
Business dealings are becoming more and more commonplace in Vietnam, as the  country’s economy is expanding at an unprecedented rate. In order to gain the respect and favour of any prospective business partners in the country, it is important to familiarise yourself with practices and etiquette that are integral to successful commerce. Doing so will communicate not only your familiarity with their way of life, but also your suitability as a partner and will underline your business acumen.  Regarding business meeting, the first meeting should not discuss business and should be seen only as an opportunity to get to know your counterpart and cultivate a good working relationship with them. While placing hands together and bowing your head is the traditional form of greeting in Vietnam, it has been all but eradicated by the westernisation of society. As a result, you should always shake the hand of a person you are meeting for the first time - especially if they are of the same sex. When meeting a female, you should wait for her to extend her hand first; if she does not, simply nod your head. Follow your new colleague’s lead in all matters. If they shake with both hands (left hand placed upon top of right), do the same.  The next important point is that the exchange of business cards is an important ritual in Vietnamese culture. Because of this, always make sure you bring a business card to exchange at any meeting, no matter how small or trivial it may seem. Ideally, this will be printed in both English and Vietnamese and you should always offer it using both hands. When receiving a card from someone else, accept it with both hands and study it thoroughly before putting it away to show respect. The translation of all documents into Vietnamese will demonstrate your regard for your prospective partners and your preparation in the business world.
