5.. C

对于否定式疑问句或前否定后肯定的反意疑问句的回答，应根据实际情况作答。若是肯定的事实，用yes，若是否定的事实，应用no。此题中的后者也认为不应该用字典。故选C。

4.. C

mustn’t表不准禁止之意；may表推测可能性。故选C。

3. D

can、 may、might都可用来表达可能性，但may、might不用于疑问句，且might表示成为现实的可能性更小。由I’m not sure可知第二空应用might。故选D。

2. A

would可用来表示过去经常性、习惯性的动作，当他在那儿时，他每天下班后都经常到街道拐角处的咖啡店。故选A。

1. A

may用在so、so that、in order that后常表目的。“我”给他发封 e-mail，这样他就可以知道什么时候接我们了。故选A。
