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

試題分析：have to 不得不  be able to能夠做某事 get used to sth習(xí)慣于某事 ，句意：亨利老人過(guò)去常常晚飯后去遛狗。但現(xiàn)在他太虛弱了而不能這么做了。故選C.
點(diǎn)評(píng)：be used to do sth被用來(lái)做某事；be used to doing sth習(xí)慣于做某事及used to do sth過(guò)去常常做某事，是中考必須掌握的基本語(yǔ)言點(diǎn)。其中，used to do sth表示過(guò)去常常做某事而現(xiàn)在已經(jīng)不這樣了。
