Question

【题目】— Today Mary is in low spirits.

— Yes, but she won’t say _______ bothers her.

A.why is it thatB.that is why

C.it is whatD.what it is that

Answer 1

【答案】D

【解析】

考查宾语从句和强调句型。句意：——今天玛丽情绪低落。——是的，但她不愿说出困扰她的是什么。此处动词say后面是宾语从句，引导词即起引导作用又做宾语从句的主语，宾语从句应该由what引导；同时此处又是对引导词的强调，it is +强调部分+that…。故选D。
