Question

He used to        to school by bike but he is used to        to school now.
A．go; walking          B．go; walk             C．going; walk

Answer 1

A

试题分析：be used to sth习惯于某事;used to do sth过去常常做某事.句意:他过去常常骑自行车去学校。但是他现在习惯了步行去学校。故选A。
点评：used to用法比较固定，需要注意use还可以作为被动语态使用，sth be used to do sth某物被用来做某事。
