—There _______ a factory here, but now it has changed into a big supermarket.
— You are so lucky to live here.

A．used to have

B．is used to be

C．used to be

D．was used to be

答案

C

解析

试题分析：be used to sth习惯于某事;used to do sth过去常常做某事. sth be used to do sth某物被用来做某事。句意：过去这儿有一家工厂，但是现在它已经变成了一家大超市。——住在这儿你太幸运了。结合语境可知选C。
点评：used to的用法比较固定，需要注意的是used to do表示过去常常做某事，be used to表示习惯于某事。前者to是不定式符号，后接动词原形。后者to是介词，后接名词或者名词性短语。Used to do结构中use相当于行为动词，有词形变化。Be used to中used相当于形容词，无词形变化。
