      动词keep主要用法归纳

      1.表示“保持”,用作连系动词,其后可接形容词或介词短语等作表语。如:

      She knew she must keep calm. 她知道她必须保持冷静。

      We’ll keep in touch with you. 我们将和你保持联系。

      2.表示“保持”,用作实义动词,其后可接动名词作宾语,但不能接不定式。如:

      Prices keep rising. 物价不断上涨。

      Please don’t keep running up and down the stairs. 请别老在楼梯上跑上跑下。

      根据语义的需要,其后可接带形容词、副词、介词短语、现在分词、过去分词等的复合结构,但不能接带不定式的复合结构。如:

      You must keep it a secret. 这事你得保密。

      Sorry to have kept you up so late. 对不起让你这么晚都没睡。

      A cold kept him in bed for three days. 一次感冒让他卧床3天。

      She kept us waiting for a long time. 她让我们等了很久。

      3.比较keep doing sth与keep on doing sth:两者均可表示反复发生的动作(即动作之间略有间隔)。如:

      They kept (on) talking about it. 他们一直在谈论此事。

      但是,如果表示持续的状态或连续不断的动作(动作之间没有间隔)时,通常只用keep doing sth。如:

      He kept standing during the meeting. 开会时他一直站着。

      另外,表示将一直在做的事继续做下去,通常只用keep on doing。如:

      He kept on working after dark. 天黑了我们还继续干。

      Don’t give up; keep on trying. 别灰心,继续努力。

      4.比较keep doing sth与keep from doing sth:前者指不停地做某事,后者指克制自己不做某事。如:

      I could hardly keep from laughing. 我简直忍不住大笑起来。

      I hope you will keep from doing anything rash. 我希望你不要鲁莽行事。

      5.比较keep sb doing sth与keep sb from doing sth:前者指使某人不停地做某事,后者指使某人不做某事。如:

      The snow kept us from going out. 下雪使我们没法出去。

      He hung around for hours and, which was worse, kept me from doing my work. 他闲待了好几个钟头,更糟糕的是,这使我也没法工作。
