They see themselves as individuals who are different from all other individuals, whether those others are Americans or foreigners. Americans may say they have no culture, since they often think of culture as an overlay of customs to be found only in other countries. Individual Americans may think they chose their own values, rather than having had their value forced on them by the society in which they were born. If you ask them to tell you something about “American culture”, they may be unable to answer and they may even deny that there is an “American culture”.Because they think they are responsible as individuals for having chosen their basic values and their way of life, many Americans dont like generalizations others make about them. Generalizations disturb Americans. They may be unhappy with the thought that they hold certain ideas and act in certain way simply because they were born and raised in the United States, and not because they had consciously thought about those ideas and ways of doing things and chosen the ones they preferred.At the same time, Americans will readily generalize about various subgroups within their own country. Northerners have fixed views about Southerners, and vice versa(反之亦然). There are fixed views of people from the country and people from the city;people from the coasts and people from inland;people from the Midwest;minority ethnic groups;Texas;New Yorkers;Californians;and so on.Therefore, Americans see few generalizations that can safely be made about them in part because they are “so individualistic” and in part because they think regional and other kinds of differences clearly distinguish Americans of various groups from each other.把职称英语页面加入收藏31 Americans, when in the United States, see themselves asA representatives of their country.B people different from person to person.C individuals much the same as foreigners.D individuals that share the same values and way of life.32 Americans may think that “American culture”A does not really exist.B is better than other cultures.C is different from other cultures.D is highly valued around the world.33 Individual Americans may think that their valuesA are based on their personal choices.B are forced on them by the society in which they were born.C can also be found in other cultures.D should be recognized the world over.34 Americans are disturbed by generalizations others make about them becauseA different Americans have different sources of origin.B not all Americans were born and raised in the U. S.C American culture has not been thoroughly studied.D they, as individuals, do not have the same ideas and ways of doing things.35 Which of the following statements is true?A Americans do not like to make generalizations about themselves on the basis of regional differences.B Americans have fixed ideas about different people coming from different regions and areas within their own country.C Americans think that they are equal to one another no matter where they were born.D Americans are trying hard to iron out their regional differences.第二篇 Hair DetectivesScientists have found a way to use hair to figure out where a person is from and where that person has been. The finding could help solve crimes, among other useful applications.Water is central to the new technique. Our bodies break water down into its parts: hydrogen and oxygen. Atoms of these two elements end up in our tissues and hair.But not all water is the same. Hydrogen and oxygen atoms can vary in how much they weigh. Different forms of a single element are called isotopes. And depending on where you live, tap water contains unique proportions of the heavier and lighter isotopes of hydrogen and oxygen.Might hair record these watery quirks? Thats what James R. Ehleringer, an environmental scientist at the University of Utah in Salt Lake City, wondered.To find out, he and his colleagues collected hair from barbers and hair stylists in 65 cities in states across the United States. The researchers assumed that the hair they collected came from people who lived in the area.Even though people drink a lot of bottled water these days, the scientists found that hair overwhelmingly reflected the concentrations of hydrogen and oxygen isotopes in local tap water. Thats probably because people usually cook their food in the local water. Whats more, most of the other liquids people drink including milk and soft drinks contain large amounts of water that also come from sources within their region.Scientists already knew how the composition of water varies throughout the country. Ehleringer and colleagues combined that information with their results to predict the composition of hair in people from different regions. One hair sample used in Ehleringers study came from a man who had recently moved from Beijing, China, to Salt Lake City. As his hair grew, it reflected his change in location.The new technique cant point to exactly where a person is from, because similar types of water appear in different regions that span a broad area. But authorities can now use the information to analyze hair samples from criminals or crime victims and narrow their search for clues.36. What does the writer say about tap water? Which of the following is NOT correct?A Tap water reflects the concentrations of hydrogen and oxygen isotopes in different regions.B Tap water is a kind of soft drink in the United States.C Tap water contains unique proportions of isotopes of hydrogen and oxygen.D Tap water is used to cook food.37. James R. Ehleringer tried to find outA if our bodies break water down into its parts.B if it is possible to collect hair samples across the country.C if tap water contains unique proportions of isotopes of hydrogen and oxygen.D if the composition of hair can indicate exactly where people are from.38. Which of the following statements is meant by the writer?A Ehleringer was successful in his research.B Ehleringer failed in his research.C Ehleringer can be a successful detective.D Ehleringers research proved successful in China.39. What does the last paragraph tell you?A The new technique can tell precisely where a person lives.B Water supplied in different regions all come from the same source.C Types of water used in different regions provide useful information for the police.D Hair samples provide the most important clues to identify crimes.40. Which of the following is closest in meaning to the title?A Human hair may help detectives to solve crimes.B Animal hair may help detectives to solve crimes.C Detectives watch hairy criminals closely.D Most detectives are hair specialists.第三篇 Ford Abandons Electric VehiclesThe Ford motor companys abandonment of electric cars effectively signals the end of the road for the technology, analysts say.General Motors and Honda ceased production of battery-powered cars in 99, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now announced it will do the same.Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or Think neighbor. It hoped to sell 5,000 cars each year and ,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700 carts have been sold so far in .“The bottom line is we dont believe that this is the future of environment transport for the mass market,” Tim Holmes of Ford Europe said on Friday. “We feel we have given electric our best shot.”The Think City has a range of only about 53 miles and up to a six-hour battery recharge time General Motors EVI electric vehicle also had a limited range, of about 0 miles.The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $,000 for the petrol version. Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles.“There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on,” Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines on vehicle emissions in the US.However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 0,000 zero-emission and other low-emission vehicles in the state by . Car manufactures hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.41.what have the Ford motor company, General Motors and Honda done concerning electric cars?A. They have started to produce electric cars.B. They have done extensive research on electric cars.C. They have given up producing electric cars.D. They have produced thousands of electric cars.42.According to Tim Holmes of Ford Europe, battery-powered carsA. Will be the main transportation vehicles in the future.B. Will not be the main transportation vehicles in the future.C. Will be good to the environment in the future.D. Will replace pe
