题目内容
18．Those who said locking after children was an easy way to make money obviously ______ such a troublesome boy，she thought．（ ）| A． | hadn't met | B． | didn't meet | C． | haven't met | D． | wouldn't meet |
分析 她想，那些说照顾孩子是一种赚钱的简单方法的人很显然没有遇到过这样的一个麻烦孩子．
解答 答案：A．
本句的主句为she thought，实际上前面的整个句子是一个宾语从句，没有遇到如此麻烦的一个孩子应该是发生在she thought之前，所以应该是"过去的过去"；因此选用过去完成时，故选A．
点评 宾语从句中的时态受制于主句的时态，当主句为过去时时，从句的时态一定要用过去时的相应时态，宾语从句中为客观真理除外．
