今天小学英语与大家分享的是keep的常用句型。

1.keep doing sth. 意为"继续干某事"，表示不间断地持续干某事，keep后不能接不定式或表示静止状态的v-ing形式，而必须接延续性的动词。如： He kept working all day, because he wanted to finish the work on time.他整天都在不停地工作，因为他想准时完成工作。 Keep passing the ball to each other, and you'll be OK.坚持互相传球，你们就行。

2.keep on doing sth. 意为"持续做某事"。如： The pupil kept on asking me the same question.这个学生不断地问我同一个问题。 I kept on thinking about the match in the afternoon.我总是想起下午的那场比赛。

3. keep...from doing sth.意为"阻止/防止„„做某事"。初中英语如：The heavy snow kept us from going out.大雪使我们不能出去。本文选自http://www.maxen.com.cn/tianjin/news/2013/1220/7909.html
