问题    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(卫生). One group of subjects was shown awful pictures of【C1】______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【C2】______to change the way they took care of their teeth than the low-fear group did.
   But were these reactions actually【C3】______into better dental hygiene practices? To answer this important question, subjects were called back to the laboratory on two【C4】______ (five days and six weeks after the experiment). They chewed disclosing wafers(牙疾诊断片)that give a red stain to any uncleaned areas of the teeth and thus provided a direct【C5】______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【C6】______changes in dental hygiene. That is, the subjects【C7】______to high-fear warnings brushed their teeth more【C8】______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【C9】______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【C10】______of the communicator. If that happens, it is unlikely that either attitude or behavior change will occur.
A)accustomed I)eligible
B)carefully J)exposed
C)cautiously K)indication
D)concrete L)occasions
E)credibility M)permanent
F)decayed N)sensitivity
G)desire O)translated
H)dimensions [br] 【C4】
选项
答案 L
解析 该空格位于数词two之后，而且后面括号中用来补充说明的内容与时间有关，据此推断空格处应该填入与时间有关的名词。根据句意，为了回答这个重要的问题，受试者们分别在实验开展五天之后和六周之后这两个时间段被召回实验室，故确定答案为L)occasions“时刻，时候”。备选名词里还有credibility“可信度，确实性”，dimensions“规模，维度”，indication“迹象，指示”，sensitivity“敏感，敏感性”，但这些词均与时间无关，故均可排除。
