词汇理解
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.

1.【C1】
F
解析：该空格位于介词of之后，名词teeth之前，而且后面有and连接的名词短语diseasedgums，据此推断空格处应该填入一个形容词，而且该词在意义上应该与diseased一致，即与疾病相关。再根据前文提到的“口腔卫生”可以推知，此处与牙齿出现的病变有关，故答案为F)decayed“腐烂的，腐败的”。decay一般作动词使用，此处的过去分词形式用作形容词。备选形容词里还有concrete“具体的，明确的”，ehgible“适当的，合适的”，permanent“永久的，永恒的”，但这些词均与疾病无关，因此不符合上下文语义，故均可排除。
2.【C2】
G
解析：该空格位于不定冠词a和形容词比较级greater之后，据此推断应该填入一个名词。根据上文可知，那些看到令人恐惧的材料的受试者显得更为焦虑，因此他们更愿意改变牙齿的护理方式，以免牙齿出现类似的病变，由此确定答案为G)desire“意愿，心愿”。备选名词里还有credibility“可信度，确实性”，dimensions“规模，维度”，indication“迹象，指示”，occasions“时刻，时候”，sensitivity“敏感，敏感性”，但均与上下文语义不符，故均可排除。
3.【C3】
O
解析：空格所在句为一般疑问句，助动词were位于句首，而且空格后为介词into，据此推知，空格处应该填入一个动词，而且该动词能和介词into搭配，且为过去分词形式。根据上下文内容可知，前一段主要提及两组受试者的不同反应，而下文主要谈论他们在口腔卫生方面的做法，由此可知，本句起到了承上启下的过渡作用，句意应该为“这些反应能够切实地转化成更好的口腔卫生行为吗”，故确定答案为O)translated“转化，转变为”。备选项里还有accustomed“使习惯于”，exposed“使暴露，使陷入”两个动词的过去分词形式，但均不符合句意，故均可排除。
4.【C4】
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。
5.【C5】
K
解析：该空格位于不定冠词a和形容词direct之后，而且后面接有介词of引出的从句，据此推断空格处应该填入一个名词。分析句子可知，句子由and和表示因果关系的thus连接，前一句提到受试者们在牙疾诊断片上被留下红色的污点，后一句提到他们对保护牙齿的重视程度，根据常识也可知，进行医疗检查就是为了发现存在的疾病或者出现的问题，因此，牙疾诊断片上留下的红色污点能够反映出人们对牙齿保护的重视程度，由此确定答案为K)indication“迹象，指示”。备选名词还有credibility“可信度，确实性”，dimensions“规模，维度”，sensitivity“敏感，敏感性”，但均不符合文意，故可以排除。
6.【C6】
D
