Question

 —Hi, Jack!
—Hi, Eric! You ________ really quiet, but now you are very outgoing.

A．used to

B．use to

C．used to be

D．use to be

Answer 1

C

試題分析：根據句意：你過去常常是很文靜的，但是現在你很外向了。故選C.
點評：be used to do sth被用來做某事；be used to doing sth習慣于做某事及used to do sth過去常常做某事，是中考必須掌握的基本語言點。其中，used to do sth表示過去常常做某事而現在已經不這樣了。
