2015年英語六級考試閱讀真題

　　Fear can be an effective way to change behavior. One study compared the effects of high-fear and low-fear appeals on changes in attitudes and behaviors related to dental hygiene (衛(wèi)生). One group of subjects was shown awful pictures of __36__ teeth and diseased gums; another group was shown less frightening materials such as plastic teeth, charts, and graphs. Subjects who saw the frightening materials reported more anxiety and a greater __37__ to change the way they took care of their teeth than the low-fear group did.

　　But were these reactions actually __38__ into better dental hygiene practices? To answer this important question, subjects were called back to the laboratory on two __39__ (five days and six weeks after the experiment). They chewed disclosing wafers (牙疾診斷片) that give a red stain to any uncleaned areas of the teeth and thus provided a direct __40__ of how well they were really taking care of their teeth. The result showed that the high-fear appeal did actually result in greater and more __41__ changes in dental hygiene. That is, the subjects __42__ to high-fear warnings brushed their teeth more __43__ than did those who saw low-fear warnings.

　　However, to be an effective persuasive device it is very important that the message not be too frightening and that people be given __44__ guidelines to help them to reduce the cause of the fear. If this isn't done, they may reduce their anxiety by denying the message or the __45__ of the communicator. If that happens, it is unlikely that either attitude or behavior change will occur.
