Question

【题目】It often takes me two hours _______ playing the violin.

A.practiceB.to practiceC.practicingD.practices

Answer 1

【答案】B

【解析】

句意：我经常花两个小时练习拉小提琴。

考查固定句型。practice是动词原形；to practice是动词不定式；practicing是动词-ing；practices是动词三单。It takes sb. some time to do sth.做某事花费某人一些时间，固定句型；it是形式主语，真正主语是动词不定式。故选B。
