情态动词can的用法小结及练习

情态动词can的用法小结

1．can的个性展示

can本身有一定含义，但不能独立存在，它必须与动词原形一起构成谓语。情态动词can没有人称和数的变化。

2．can的具体用法

(1)表示“能；会”，指脑力或体力方面的“能力”。如：

I can speak English.我会说英语。

Jim can swim but I can't.吉姆会游泳，但我不会。

(2)表示许可，意为“可以”，常用于口语中，这时相当于may。如：

Can/May I have a cup of tea，please？我可以喝一杯茶吗？

3．can的句式表演

(1)肯定句：主语＋can＋动词原形＋其他。如：

Mary can dance.玛丽会跳舞。

You can go to watch TV.你可以去看电视。

(2)否定句：主语＋can't＋动词原形＋其他。如：

He can't play the guitar.他不会弹吉他。

You can't pass the ball like this.你不能像这样传球。

(3)一般疑问句：Can＋主语＋动词原形＋其他？

肯定回答：Yes，主语＋can.

否定回答：No，主语＋can't.如：

—Can you sing an English song for us？你可以为我们唱一首英文歌曲吗？

—Yes，I can./No，I can't.好的，我可以。/不，我不能。

【注意】肯定回答中用certainly，语气更肯定；否定回答中用sorry，语气则更委婉、客气。如：

—Can you sing？你会唱歌吗？

—Certainly，I can./Sorry，I can't.我当然会。/很抱歉，我不会。

(4)特殊疑问句：特殊疑问词＋can＋主语＋动词原形＋其他？如：

What can your mother do？你的妈妈会什么？

4．can的巧记口诀

表能力，要用can。陈述句里记特点。

肯定can后加动原，否定can后not连。

疑问句，can 提前；

肯定回答“Yes，主语＋can”；

否定回答“No，主语＋can't”记心间。语法精练
