问题
选择题
--- ________ you ________ to live in Qiandao Lake?
--- Yes , I did. But in 2005, I came to Hangzhou with my family.
A．Did, used
B．Were, use
C．Do, use
D．Did, use
答案
答案：D
题目分析：be used to sth习惯于某事;used to do sth过去常常做某事.根据答语，可知上文是一般过去时态，你过去常常住在青岛湖吗？当有助动词体现时态时，实意动词用原形，故选D。
点评：used to用法比较固定，需要注意use还可以作为被动语态使用，sth be used to do sth某物被用来做某事。
