Question

Old Henry ­­­­­­_________ take his dog for a walk after supper. But these days he is too weak to do that.

A．has to

B．is able to

C．used to

D．got used to

Answer 1

C

试题分析：have to 不得不  be able to能够做某事 get used to sth习惯于某事 ，句意：亨利老人过去常常晚饭后去遛狗。但现在他太虚弱了而不能这么做了。故选C.
点评：be used to do sth被用来做某事；be used to doing sth习惯于做某事及used to do sth过去常常做某事，是中考必须掌握的基本语言点。其中，used to do sth表示过去常常做某事而现在已经不这样了。
