Question

Mother ________ us stories when we were young.

1. A.
   is used to telling
2. B.
   used to tell
3. C.
   used to telling
4. D.
   was used to tell

Answer 1

B
解析：
解析：本题考查used to do和be used to doing结构的用法区别。used to do意为“过去常常做某事”；
be used to doing意为“习惯于做某事”。根据题意“我们小的时候，妈妈常常给我们讲故事。”可判断是过去常常讲故事 (暗含现在长大了，不讲故事了),因此选B。
