本文是叙述一个人是勇敢还是懦弱，关键是看面临危险处境时的表现。
1. C。根据后面的or来判断应该用if来引导宾语从句，表示你"是否"认为你是一个勇敢的人还是一个懦夫。
2. A。与后面的a coward相对应， 应填"勇敢的"。
3.B。因为前面有否定词never，相当于not，因此选until，not ... until表示"直到......才"。
4.C。根据下文的内容答案只能选think。
5.D。根据下文they act like cowards来判断，有些人自认为勇敢，当"面临危险"的时候，举止就像懦夫。
6.C。与上文相反进行对比论证，有些人看起来像懦夫，但当遇到危险的时候，实际行动就像"英雄"一样。
7.C。根据后面两句中的worried来判断，答案应该是与懦夫相近的词，只有"紧张的"人与懦夫意思相近。
8.C。从上下句来看是表示时间的先后，用then来承接后来所发生的事。
9.D。因为美国的季节与中国的相近，时间又是元月五号，所以水是"冰冷的"。
10.B。根据上文的不害怕可知，他应该是保持"冷静"，其余选项不符合语境。
11.D。因为他跳入水中，所以是"游"向那位妇女。
12.C。根据常识，人掉在水中，头应该在水"上"能够呼吸，不呛水，其余不符合语境。
13.D。根据前面的seventy-eight来判断，她不是第七十九个遇难者，而是获救了。
14.A。根据后面的"害怕"可判断出答案。
15.A。根据对后面句子的内容的逻辑推理可知，前面应是：血里如果"有"了肾上腺素，你就会感到越来越强......。
16.C。根据上文，血里有肾上腺素，你就会越来越强壮随时"准备"搏斗或跑开。be ready to do sth.是"准备、乐意做某事"。
17.C。根据上一句话，得出答案：当这种情况"发生"时。肌肉就会变得僵硬。这也是医学常识。
18.B。根据上文，肌肉变硬了，结果你就一点也"不能"动了。
19.D。根据前后的因果关系，这是说明原因的，why引导表语从句，表示"原因"。
20.D。该句后面省略了that, "so+形容词＋that..."是一个固定句型。
