1. Jerry lived in Yangzhou when he was young.

　　Really? How long

　　there?

　　A. has he lived B. had he lived C. did he live D. has he been living

　　该题考时态，答案为C。

　　解析：本题易混淆的答案为A。A为现在完成时态，表示现在还住在Yangzhou。题目意思为曾住在Yangzhou，显然现在不住在那儿了，故选C。

　　2. It is the library

　　we often borrowed some novels when we studied here, isnt it?

　　A. that B. where C. which D. 不填

　　该题考定语从句，要求会区别于强调句。答案为B。

　　解析：如果是强调句，必须在library前面加状语in，强调地点状语，句子为it is in the library that we often borrowed some novels when we studied here, isnt it?本题为定语从句，这里的it is相当于this is，其中名词library为先行词，where引导的定语从句修饰library。
