选择题
I used to ______ in the morning, but now I’m used to _____ before going to bed.
A．read; read
B．reading; read
C．read, reading
D．reading, reading
答案
答案：C
题目分析：be used to sth/doing sth习惯于某事;used to do sth过去常常做某事.句意:我过去常常在早晨读书，但是我现在习惯了在睡觉前读书。故选C。
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。
