题目内容

 ______ used to ______ a post office near my house.

A. There; be  B There; have  C. It; be      D. There; having

 

【答案】

A

【解析】

试题分析:句意:我的房子附近过去有一个邮局。There be句型表示某地有某物,have表示某人有某物。Used to do sth过去常常做某事,to是不定式符号,后面接原形动词,故选A。

考点:there be句型的时态

点评:There be句型表示“某地(或某时)存在有某人(或某物),而并非某地(某人、某物或某时)拥有什么东西”,其实质是倒装句。其也有时态变化,要借助于不同的助动词。但是当助动词是be动词时,一般可以省略,只用一个be动词就行。
