高中题选哪个？选c还是d?为什么？

Question

They started_____ friendship really meant.A. Understanding what. B. understanding which C. to understand what D. to understand

Answer 1

你好，选A。start后面用doing sth. 这里meant是mean的过去式，用what来引导宾语从句。

Answer 2

C
start to do 表示才开始做什么事,根据句子意思,A,B排除.再根据翻译,即可知,to do 后面引导的是个从句,由what引导

Answer 3

d
friendship really meant.是understand 的宾语
friendship really meant.:友谊真正的意思本回答被提问者采纳
