Question

There________ a lot of rubbish there in the past. But now it has turned into a clean place.

A. used to be    B. used to have

C. was used to being    D. was used to having

Answer

A

【解析】句意：那儿过去有许多垃圾。但是现在它变成了一个干净的地方了。前句是there be结构，其动词要用be；过去常常：used to+动词原形。故选Ａ。

点睛：1.there be结构的中心词是be的恰当形式。其一般将来时态为：there will be…；其used to结构为：There used to be；2.过去常常：used to+动词原形；习惯于做某事：be used to doing sth；被用来做某事：be used to do sth 。
