In a physical education class, 20 students were tested on archery target shooting. These students were then given a two-day training course in archery technique. The students were tested again and showed a 30 percent increase in accuracy. This result proves that the course was effective in increasing people’s target-shooting accuracy.　 Which of the following, if true, gives the strongest support to the argument above?

Task II(20 points)　　Directions:Write on the topic given below in no less than about 160 words on the Answer Sheet. In your essay, you should first outline your ideas, and then give examples.　　Topic: What, in your opinion, is the best way to keep fit and healthy?

Animal rights are a controversial topic right now. Actually, the debate is focused mainly on animal testing. The following are opinions from both sides. Read the excerpts carefully and write your response in about 300 words, in which you should:　　1. summarize briefly the opinions from both sides, and then　　2. give your comment.　　Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks.　　Animals are used for research in a variety of settings, including tests to determine the safety of drugs, cosmetics and other substances. Whether or not humans should use animals for testing purposes, however, is a controversial subject.　　Dr. Bob Miller, a medical researcher from Michigan State University, states that one of the primary advantages of animal testing is that it allows researchers to develop new medications and treatments, advancing the field of medicine and enhancing the health of society. For instance, many drugs used to treat or prevent cancer, HIV, diabetes, infections and other medical maladies have resulted from tests performed on animals.　　Moreover, animal testing enables scientists and researchers to test the safety of medications and other substances with which humans have regular contact. Drugs, for instance, may pose significant risks to humans, so testing them on animals fast gives researchers a chance to determine drugs’ safety before human trials are performed. While scientists are cognizant of the differences between humans and animals, the similarities are considered significant enough to produce relevant, useful data that they can then apply to humans. Thus, animal testing reduces harm to humans and saves lives.　　However, Prof. Abhay Shina, a leading critic of animal testing, points out that the major disadvantage to animal testing is that a significant number of animals are harmed or die as a result of experiments and testing. Unfortunately, many of the substances used on animal subjects never receive approval for human use or consumption. Humans receive no direct benefits as a result of the deaths of these animals. He also argues that animals are dissimilar enough from humans to make the results of animal tests unreliable. A related criticism is that testing induces stress in the animals, meaning that the subjects do not react to experimental substances in the same way that they might in more natural circumstances, making the results of experiments less valid.　　Using animals as research subjects is also expensive, because the animals require food, shelter, care and treatment in addition to the costs of experimental substances. Long-term or multi-phase tests can increase the costs of the practice as well. The actual price paid for the animals is also worth consideration; there are companies that breed and sell animals specifically for testing purposes.
