问到英语语法问题.
2.One of the most widely discussed problems of recent years has centered around
_____ has come to be called the "gneration gap".(选B,为什么不是选C?)
A. that B. what C. which D. how
”可以用来引导宾语从句的是what “,that就不可以了吗??
▼优质解答
答案和解析
around后是介词宾语从句,从句中缺主语,故排除A,D,what与which之争为前者无范围,后者有范围.
E.g.What do you like?
Which do you like,this one or that one?
