【答案解析】
1．D。must表示推测。根据句意：他们一定正在等我们。所以用must be waiting。
2．D。由even though可知该题意为：她很勇敢，尽管她腿受了伤，她仍然设法独自回家了。而be able to= manage to，有克服困难设法成功之意。
3．A。cannot / can not / never … too/ enough是一固定搭配，表示“越……越好”、“再……也不过分”。
4．C。考查情态动词will的用法。will表示意志、意愿和决心。
5．B。used to和would都有“过去常常”之意，但used to有今昔对比之意，现在再也不这样了。而would无此用法。
6．C。解此题的关键：一、掌握反意疑问句的基本构成，即“前肯后否，前否后肯”。二、了解used to构成的反意疑问句有两种 （didn’t和usedn’t或usen’t）。三、知道there构成的反意疑问句可由there直接构成，而不用it，所以选择C。
7．B。can作为情态动词，它有一特殊用法，即：表示“有时会”= is sometimes等一般情况。句意为：我们家住山顶，所以有时夏天风会很大。
8．B。shall用于第一、三人称疑问句时表示征求对方意见或指示。二、三人称表示说话人的命令、警告、允诺或威胁。
9．B。should意为“竟然”。should have done意为“竟然做了某事”。句意：我很惊讶，他竟然比赛输了。
10．A。had better是一特殊情态动词，它可以写成better，但无论是had better，还是better，其反意疑问句均由had引导。此外，还遵循“前肯后否”的原则。故选A。
11．A。此题考查情态动词ought to的特殊用法。它有表示“道德法律上的必须”之意。此句意为：“先生，您不能在这捕鹿，它们是国家保护动物”。can’t虽有“不能、不准”之意，但它不表示“法律上的不准，道义上的不能”之意，所以排除B。oughtn’t to相当于shouldn’t，但前者语气更为强烈。won’t表示“不愿、不能”，故排除。needn’t表“不必”，不符合题意。因此排除D。
12．A。can不能用于肯定句中表示推测；will表将来或意愿；should have done意为“本应该……却未……”。句子表达的是一种对过去的猜测，但可能性不大。
13．D。因对话是对过去事情的推测，所以不能选择A和B。从上句意义可知：已坐了5个人的小车里再挤一个人一定不是舒服的旅行。答案为D。
14．C。表示对未来可能出现的一种事实的推测，但不是很肯定。
15．D。谚语：“三人行，必有我师”。
16．A。本句意为“你能把那本我给你打电话时你提到的那本书借给我吗?”，用过去进行时表示对过去情节，场面的描述。
17．A。shall用于第一、第三人称表示请求允许，“让这个新来者试试好吗?”
18．C。“我们本不该觉得这么累，我们只是参加了个聚会嘛”。have been to是已发生的事实，“本不该”也是已经存在的状况。shouldn’t have felt是对已存在的情况的虚拟。shouldn’t“(照常理)本不应该”。
19．B。shall用于第三人称表示征求许可。
20．B。第一句表示要“拜访Mr Richardson”；第二个人因此说我给他发个电子邮件“so (that) he may know”以便于他可以知道“什么时候接我们(期待我们到达)”故选B。
21．C。说话人在主句中使用了过去时态，因此，用来修饰从句的让步状语从句就必定是过去时态，这样，就排除了A、D项。should have done表示的是责备对方应该做某事而没有做，上句已经说明是
