Question

--- What did your parents think about your decision?
--- They always let me do _______ I think I should. 

A．when

B．that

C．how

D．what

Answer 1

D

主要测试宾语从句。句子中动词do缺少宾语，另外省略句I should （do）中也缺少宾语，该题也属于所选词应该起到双重作用，因此答案为what。句子意思----你父母感觉你的决定如何啊？----他们总是让我做我认为应该做的事情。例如：I will do what I can （do）to help the old man。我尽可能做自己能做的事来帮助那位老年人。
