18、 Even people who spent just a few hours a week on the Internet experienced more bad feelings and loneliness than those who was online less frequently, the two-year study showed. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Ne

19、t would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time available for family and friends may account for the drop in psychological health, researchers hypothesized (推测). Faceless,

20、 bodiless “virtual“(虚的) communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives. “But it“ s important t

21、o remember this is not about the technology, it“ s about how it is used,“ says psychologist Christine Riley of Intel, one of the study“ s sponsors (发起人). “It really points to the need for considering social factors in terms of how you design applications and services for technology.“（分数：10.00）(1).Wh

Although science has made enormous steps in making food more fit to eat, it has, at the same time, made m

28、any foods unfit to eat. Some research has shown that perhaps forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illnesses because of the food that is characteristic in these cultures. That food related to illn

29、ess is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on

30、 the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for

31、 medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.（分数：10.00）(1).What is the main

32、 topic of the passage?（分数：2.00）A.Food and our healthB.Food and additivesC.Food and cancerD.Food and culture(2).All of the following statements are true EXCEPT_.（分数：2.00）A.Forty percent of cancer is caused by problems related to food.B.Researchers have known about the potential danger of food additiv

A package can sometime

36、s motivate people to buy products. For example, a little child might ask for a breakfast food contained in a box with a picture of a TV character. The child is more interested in the picture than in breakfast food. Pictures for children to color or cut out, games printed on a package, or a small gif

37、t inside a box also motivate many children to buy products - or to ask their parents to buy for them. Some packages suggest that a buyer will get something for nothing. Food products sold in reusable containers are examples of this. Although a similar product in plain container might cost less, peop

38、le often prefer to buy the product in a reusable glass or dish, because they believe the container is free. However, the cost of the container is added to the cost of the product. The size of a package also motivates a buyer. Maybe the package has “Economy Size“ or “Family Size“ printed on it. This

39、suggests that the larger size has the most product for the least money. But that is not always true. To find it out, a buyer has to know how the product is sold and the price of the basic unit. The information on the package should provide some answers. But the important thing for any buyer to remem

40、ber is that a package is often an advertisement. The words and pictures do not tell the whole story.
