21、 answers on ANSWER SHEET 1. 40 Many Americans have a grossly distorted and exaggerated view of most of the risks surrounding food. Fergus Clydesdale, head of the department of food science and nutrition at the University of Massachusetts-Amherst, says bluntly that if the dangers from bacterially con

22、taminated chicken were as great as some people believe, “The streets would be littered with people lying here and there.“ Though the public increasingly demands no-risk food, there is no such thing. Bruce Ames, chairman of the biochemistry department at the University of California, Berkeley, points

23、 out that up to 10% of a plants weight is made up of natural pesticides, says he: “Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare.“ And many naturally produced chemicals, though occurring in tiny amounts, prove in laboratory tests to be strong carcinogens

24、a substance which can cause cancer. Mushrooms might be banned if they were judged by the same standard that apply to food additives. Declares Christina Stark, a nutritionist at Cornell University: “Weve got far worse natural chemicals in the food supply than anything man-made.“ Yet the issues are no

25、t that simple. While Americans have no reason to be terrified to sit down at the dinner table, they have every reason to demand significant improvements in food and water safety. They unconsciously and unwillingly take in too much of too many dangerous chemicals. If food already contains natural car

26、cinogens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small amounts of contaminants generally found in food and water, at least a few individuals will probably get cancer one day because of what they eat and drink. To make good food and water

27、 supplies even better, the Government needs to tighten its regulatory standards, stiffen its inspection program and strengthen its enforcement policies. The food industry should modify some long-accepted practices or turn to less hazardous alternatives. Perhaps most important, consumers will have to

28、 do a better job of learning how to handle and cook food properly, The problems that need to be tackled exist all along the food-supply chain, from fields to processing plants to kitchens. 41 What does the author think of the Americans view of their food? （ A） They overstate the governments interfer

29、ence with the food industry. （ B） They are overoptimistic about the safety of their food. （ C） They overestimate the hazards of their food. （ D） They overlook the risks of the food they eat. 42 The author considers it impossible to obtain no-risk food because_. （ A） no food is free from pollution in

30、 the environment （ B） pesticides are widely used in agriculture （ C） many vegetables contain dangerous natural chemicals （ D） almost all foods have additives 43 By saying “they employ chemical warfare“ (Line 4, Para. 2), Bruce Ames means_. （ A） plants produce certain chemicals to combat pests and di

31、seases （ B） plants absorb useful chemicals to promote their growth （ C） farmers use man-made chemicals to dissolve the natural chemicals in plants （ D） farmers use chemicals to protect plants against pests and diseases 44 The reduction of the possible hazards in food ultimately depends on_. （ A） the

32、 government （ B） the consumer （ C） the processor （ D） the grower 45 What is the message the author wants to convey in the passage? （ A） Eating and drinking have become more hazardous than before. （ B） Immediate measures must be taken to improve food production and processing. （ C） Health food is not

33、 a dream in modern society. （ D） There is reason for caution but no cause for alarm with regard to food consumption. 45 The Nile made Egypts civilization possible. The river is more than 400 miles long. In its fertile valley crops are grown for food and cotton for clothing. Mud from the river bottom

34、 makes good bricks for houses. Thus ways of getting food, clothing and shelter were close for the Egyptians. The Nile is a highway for the people of Egypt. Flat bottomed boats and large narrow barges carry products from one city to another. There are also passenger boats on the Nile, carrying people

35、 up and down the river. In ancient times huge blocks of stones were floated down the river on barges. These stones are used in making buildings and monuments. For thousands of years the Egyptians have depended on the Nile for their crops. The land on both sides of the Nile is desert, where crops can

36、not be raised. But crops grow well in the Nile Valley. In fact, several different crops are often grown on the same land during the same year. Once the Nile flooded each year, overflowed its banks, and carried rich soil in land every summer. These floods were caused by early summer rains. At present

37、 there is a series of dams on the Nile. Water raised high in the river each summer as usual. The people do not let the Nile flood, however. They store the water behind dams. It is now possible to use the water as needed, not just at flood time. 46 In the past_. （ A） there was rain all the year long

38、（ B） the Nile flooded every year （ C） the Nile became deeper and deeper after each rainfall （ D） the Nile was not a long river 47 Egyptians have grown crops well_. （ A） on both sides of the Nile （ B） on the land near the desert area （ C） on the Nile valley （ D） far away from the desert area 48 In th

39、e fertile valley of the Nile_. （ A） bricks for houses are made （ B） different crops are raised on the same land （ C） only cotton can grow well （ D） people grow all crops except cotton 49 “The Nile is a highway for the people of Egypt“ means_. （ A） cars and trucks can move as fast as possible along i

40、t （ B） the river bottom can serve as a road in dry season （ C） the river is an important water transportation line in Egypt （ D） on the river there are a lot of boats and people 50 Which of the following can best summarize the passage? （ A） The Nile is the source of flood. （ B） The Nile is a highway

41、 for the people in Egypt. （ C） The flat bottomed boats have been used. （ D） The Nile made Egypts civilization possible. 50 In Jane Collards opinion, stress is becoming an increasingly common feature of the workplace. Stress is a highly individual reaction, which varies considerably from person to pe

42、rson, and it is difficult for some employees to avoid it. Indeed, stress is regarded by many as part of the organizational culture of our institutions: it comes with the job. Recent figures indicate that time taken off work because of stress has increased by 50 percent since the 1950s. Undoubtedly,

43、changes in working conditions have led to greater pressure at work at all levels. With reductions in staffing, workloads for individual employees have increased. In addition, many employees are left worrying about the security of their jobs. On the stress management courses that she runs, Jane Colla

44、rd tries to make the trainees realize that stress in itself is not harmful. Everyone needs a certain level of stress to enable them to feel motivated and to perform effectively. A complete absence of stress can be as damaging as overstress, since it can make people lose interest in their work, and e

45、ven lead to depression. The difficulties occur when the amount of stress rises above a level which is healthy for a particular individual. If this happens, the effects are very obvious and the trainees are taught to recognize the signs. Stress may be expressed physically, for example through headach

46、es and tiredness, or through emotional problems such as depression. A person suffering from stress may also start to behave differently, and can be difficult to deal with. While it may not always be possible to prevent stress, there are a number of ways in which it can be controlled. The first thing

47、 that the trainees learn is how to manage their time effectively. This involves, first of all, setting realistic goals for both the short and long term. Once this framework has been established, tasks are then prioritized on a daily basis. The trainees are also reminded that when they are under pres

48、sure the less important items should be left, and they should never hesitate to delegate. Everyone is encouraged to look at ways of reducing “wasted time“, for example by grouping similar tasks together or dealing with items immediately. Jane feels that one of the most useful features of the course

49、is that it enables trainees to deal with those demands or deadlines that they regard as unreasonable. They are encouraged to avoid being defensive, but at the same time they are advised not to be afraid of saying “no“. They are asked to give reasons only if necessary. The training helps them to foresee difficult situations or unwanted demands, and they learn how to prepare themselves mentally. Everyone is encour
