解析:must + have done:用于肯定句,表示推测,意为“一定(已经)……”。
can + have done:用于否定句或疑问句,表示推测,意为“可能(已经)……”。
could + have done:可用于肯定句、否定句或疑问句,表示推测、责备或遗憾等,意为“可能……”、“本来可以……”、“本来应该……”等。
should [ought to] + have done:可用于肯定句、否定句或疑问句,表示责备或遗憾等,意为“本来应该……”。
need + have done:用于否定句或疑问句,用于否定时意为“本来不必”,用于疑问句时意为“有必要……吗”。
may + have done:用于肯定句或否定句,表示推测,意为“可能(已经)……”。
might + have done:用于肯定句或否定句,表示推测,意为“可能(已经)……(此时 might 可换为 may);另外还可以表示过来可能发生的事结果未发生,意为“本来会……”(此时 might 不能换为 may)。
本句中既然天气是晴朗的那么就没必要在带雨伞了,故选D。
