Question

---Sam, you always run slowly every morning. Do you like it?
---Not really, but          .

A．I used to it	B．I’m used to it
C．I used to do it	D．I’m used to do it

Answer 1

B

试题分析：句意：萨姆，你总是每天上午慢跑。你喜欢吗？不是真的喜欢，但是我习惯了。be used to do sth,被用来做……，be used to doing sth / sth习惯于做……，used to do sth,过去常常做某事。故选B。
