Question

【题目】Mum didn't believe .

A.what the doctor had told herB.what had the doctor told her

C.what the doctor has told herD.what has the doctor told her

Answer 1

【答案】A

【解析】

句意：妈妈不相信医生告诉她的事。

考查宾语从句。宾语从句三大要素为：时态，语序，引导词，宾语从句皆为陈述句语序，所以排除B、D两个选项，因主句中有didn’t表示过去，主过从过，所以从句也要是相应的过去式，B选项是现在完成时，不符合时态，排除；A选项都符合，故选A。
