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.ACADEMICS AREN’T THE PROBLEMStudies about how students use their time might shed light on whether they face increased academic and financial pressures compared with earlier eras.Based on data about how students are spending time, academic or financial pressures don’t seem to be greater now than a generation ago.The data show that full-time students in all types of colleges study much less now than they did a generation ago - a full 10 hours a week less. Students are also receiving significantly higher grades. So it appears that academic pressures are, in fact, considerably lower than they used to be.The time-use data don’t suggest that students feel greater financial pressures, either. When the time savings and lower opportunity costs are factored in, college appears less expensive for most students than it was in the 1960s. And though there are now full-time students working to pay while in college, they study less even when paid work choices are held constantly.In other words, full-time students do not appear to be studying less in order to work more. They appear to be studying less and spending the extra time on leisure activities or fun. It seems hard to imagine that students feeling increased financial pressures would respond by taking more leisure.Based on how students are spending their time then, it doesn’t look as though academic or financial pressures are greater now than a generation ago. The time-use data don’t speak directly to social pressures, and it may well be that these have become more intense lately.In one recent set of data, students reported spending more than 23 hours per week either socializing with friends or playing on the computer for fun. Social activities, in person or on computer, would seem to have become the major focus of campus life. It is hard to tell what kinds of pressures would be associated with this changeThe word “Academics” in the title mostly means___________

He said that it would not be long before computer (27)______ is one billion times more powerful than the human brain. Mr Kurzweil joked that many years ago, people thought he was a little crazy for predicting computers would be as intelligent as humans. His thinking has stayed the same but everyone else has changed the way they think. He said: “My views are not radical any more. I've actually stayed (28)______. It's the rest of the world that's changing its View.” He highlighted examples of high-tech things we use, see or read about every day. These things make us believe that computers have intelligence.

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. Plants and animals will find it difficult to escape from or adjust to the effect of global warming. Scientists have already observed shifts in the lifecycles of many plants and animals, such as flowers blooming earlier and birds hatching earlier in the spring. Many species have begun shifting where they live or their annual migration patterns due to warmer temperatures. With further warming, animals will tend to migrate toward the poles and up mountainsides toward higher elevations. Plants will also attempt to shift their ranges, seeking new areas as old habitats grow too warm. In many places, however, human development will prevent these shifts. Species that find cities or farmland blocking their way north or south may become extinct. Species living in unique ecosystems, such as those found in polar and mountaintop regions, are especially at risk because migration to new habitats is not possible. For instance, polar bears and marine mammals in the Arctic are already threatened by dwindling sea ice but have nowhere farther to go. Projecting species extinction due to global warming is extremely difficult. Some scientists have estimated that 20 to 50 percent of species could be committed to extinction with 2 to 3 Celsius degrees of further warming. The rate of warming, not just the magnitude, is extremely important for plants and animals. Some species and even entire ecosystems, such as certain types of forest, many not be able to adjust quickly enough and may disappear. Ocean ecosystems, especially fragile ones like coral reefs, will also be affected by global warming. Warmer ocean temperatures can cause coral to “bleach”, a state which if prolonged will lead to the death of the coral. Scientists estimate that even 1 Celsius degree of additional warming could lead to widespread bleaching and death of coral reefs around the world. Also, increasing carbon dioxide in the atmosphere enters the ocean and increases the acidity of ocean waters. This acidification further stresses ocean ecosystems.From “global warming” by Michael Mastrandrea and Stephen H.SchneiderThe bleaching of coral reefs as mentioned in paragraph 4 indicates ________.

For instance, polar bears and marine mammals in the Arctic are already threatened by dwindling sea ice but have nowhere farther to go. Projecting species extinction due to global warming is extremely difficult. Some scientists have estimated that 20 to 50 percent of species could be committed to extinction with 2 to 3 Celsius degrees of further warming. The rate of warming, not just the magnitude, is extremely important for plants and animals. Some species and even entire ecosystems, such as certain types of forest, many not be able to adjust quickly enough and may disappear. Ocean ecosystems, especially fragile ones like coral reefs, will also be affected by global warming. Warmer ocean temperatures can cause coral to “bleach”, a state which if prolonged will lead to the death of the coral. Scientists estimate that even 1 Celsius degree of additional warming could lead to widespread bleaching and death of coral reefs around the world. Also, increasing carbon dioxide in the atmosphere enters the ocean and increases the acidity of ocean waters. This acidification further stresses ocean ecosystems.From “global warming” by Michael Mastrandrea and Stephen H.SchneiderAccording to paragragh 2, when their habitats grow warmer, animals tend to move ________.

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. Plants and animals will find it difficult to escape from or adjust to the effect of global warming. Scientists have already observed shifts in the lifecycles of many plants and animals, such as flowers blooming earlier and birds hatching earlier in the spring. Many species have begun shifting where they live or their annual migration patterns due to warmer temperatures. With further warming, animals will tend to migrate toward the poles and up mountainsides toward higher elevations. Plants will also attempt to shift their ranges, seeking new areas as old habitats grow too warm. In many places, however, human development will prevent these shifts.

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 following questions from 31 to 35:Centuries ago, man discovered that removing moisture from food helped to preserve it, and that the easiest way to do this was to expose the food to sun and wind. In this way the North American Indians produced pemmican (dried meat ground into powder and made into cakes), the Scandinavians made stock fish and the Arabs dried dates and apricots.All foods contain water - cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked.Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. The methods used vary, but in general the fruit is spread out on trays in drying yards in the hot sun. In order to prevent darkening, pears, peaches and apricots are exposed to the fumes of burning sulphur before drying. Plums for making prunes, and certain varieties of grapes for making raisins and currants, are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating, so increasing the rate of drying.Nowadays most foods are dried mechanically; the conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110°C at entry to about 45°C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.This passage is mainly ________.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct questions from 43 to 50.The city of Detroit, in the USA, was once compared to Paris. It had a broad river, smart streets and historically important architecture. Then, in the 20th century, it became ‘Motor City’. For a time, most of the world’s cars were made here. There was regular work and a good salary in the motor industry. A worker at one of the car factories could own a home, plus a boat, maybe even a holiday cottage. Some say America’s middle class was born in Detroit – new highways certainly made it easy for workers to move from the city centre to the suburbs in the 1950s. But in the early years of the 21st century, Detroit became America’s poorest big city.In less than five decades the once lively Motor City lost more than half its population. It became known as a city that was failing, full of ruined buildings, extensive poverty and crime. Newspapers and magazines told stories of derelict homes and empty streets. Photographers went to Detroit to record the strange beauty of buildings and city blocks where nature was taking over again. What went wrong in Detroit?The city is now 69th among US cities for the number of people per square mile. The population fell for several reasons. Partly, it was because people moved to the suburbs in the 1950s. Then there were the shocking riots in 1967, which scared more people away from the city. Then there was the dramatic fall in car manufacture as companies like General Motors and Chrysler faced huge difficulties. And finally, in 2008, came the global financial crisis. Many of Detroit’s people are poor – half of the city’s families live on less than 25,000 dollars a year.In 2013, the city did something unusual: it declared itself bankrupt. It was the largest city bankruptcy in US history, at approximately 18-20 billion dollars. Now that the city is free of debt, it has money to do some of what needs to be done. It has replaced about 40,000 streetlights so that places feel safer. The police arrive in answer to calls in less than 20 minutes now, instead of the hour it used to take. And about a hundred empty houses are demolished each week to make space for new buildings. With the nation’s biggest city bankruptcy behind it, Detroit is also attracting investors and young adventurers. The New Economy Initiative gave grants of 10,000 dollars to each of 30 new small businesses. It seems that every week a new small businesses. It seems that every week a new business opens in Detroit – grocery stores, juice bars, coffee shops, even bicycle Detroit _______.
