Question

He lived in London for 3 months ,during ____ time he learned some English.
A.this B.which C.that D.the
why?

Answer 1

选B
本题考查定语从句,英语中句子结构要完整,不能像汉语那样随便加逗号,若加了逗号,一般要用连词连接,分成主句和从句.本题就属于这种情况,即两个句子之间有逗号,但没有连接词,所以我们要选一个关系代词构成非限制性定语从句,由于that不能用于非限制性定语从句,而the和this都不是关系代词,所以都排除,而选which [用于指代前面的two months]
