Great changes have taken place in my home town. It’s no longer it was ten years ago I

问题补充：

Great changes have taken place in my home town. It’s no longer it was ten years ago, I spent my childhood there.

A. what, when

B. that, where

C. as, which

D. which, that

答案：

(答案→)A. what, when

B. that, where

C. as, which

D. which, that

解析：本题第一空是一个表语从句，what引导起这个宾语从句，并在句中做为系动词was的表语，构成系表结构。第二空是一个定语从句，先行词是ten years ago，后面的定语下降的句子结构很完整，故使用关系副词引导该定语从句。句义：在我的家乡发生了巨大的变化。它已经不再是前的了，在那里我在努力度过了自己的童年。故A正确。
