1. Questions27-11are based on the following passage.
  Going online is a favorite recreation for millions of American children. Almost 10 million ( 14 percent) of America's 69 million children are online. The Internet both entertains and educates children, however, there are some possible negative consequences for children who access kid-based Web sites. Advertising on kid-based Web sites has become both a rapidly growing market for consumer companies and a concern for parents. With a click on an icon, children can link to advertisers and be granted tremendous spending power.   Children are an important target group for consumer companies. Children under age 12 spent $14 billion, teenagers another $ 67 billion, and together they influenced $160 billion of their parents' incomes.
  Many critics question the appropriateness of targeting children in Internet advertising and press to require that children be treated as a "special case" by advertisers. Because children lack the analytical abilities and judgment of adults, they may be unable to evaluate the accuracy of information they view, or understand that the information they provide to advertisers is really just data collected by an advertiser. Children generally lack the ability to reject the release of personal information to an advertiser, an even greater problem for children when they are offered incentives(刺激) for pro- viding personal information, or when personal information is required before they are allowed to register for various services. Children may not realize that in many cases these characters provide hot links directly to advertising sites.
  The Internet does present some challenges for advertisers who want to be ethical in their marketing practices. Many advertisers argue that we underestimate(低估) the levels of media awareness shown by children. By the age of seven or eight most children can recognize an advertisement and know that its purpose is to sell something and are able to make judgments about the products shown in advertisements. However, this somewhat optimistic and decidedly libertarian view of children runs aground when we realize that they are ( like a surprising number of adults) unable to judge accurately between entertainment and advertising. Adults can fend for themselves but, as marketers, we should be explicit (明确的) about our purpose when advertising to children on the Interact.
According to the first paragraph, children as an Internet market___________
A.are becoming increasingly rational
B.are using Internet at an earlier and earlier age
C.have created a growing advertising market
D.are overtaking the adult market due to their spending power

In 1945, government researchers realized that nitrates (硝酸盐) and nitrites (亚硝酸盐), 5 used to preserve colors in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging 6 of processed food are helpful or harmful. The additives that we eat are not all so 7 . Farmers often give penicillin to beef and fowl and because of this, penicillin has been found in the milk of 8 cows. Sometimes similar drugs are given to animals not for medical purposes, but for 9 reasons. The farmers are simply trying to fatten the animals in order to 10 a higher price on the market. Although the Food and Drug Administration has tried repeatedly to control these procedures, the practices continue.
