语法提优 情态动词can的用法
知识精讲
注意:四年级could作为拓展部分选择性进行讲解。
can是情态动词,没有人称和数的变化,它后面的动词必须用原形。
1.肯定句:主语+can+动词原形+其他.
如:He can play basketball.他会打篮球。
2.否定句:主语+can't+动词原形+其他.
如:My sister can't skate.我的妹妹(姐姐)不会溜冰。
3.一般疑问句:Can+主语+动词原形+其他?
肯定回答:“Yes,.can.”;否定回答:“No,...can't.”。如:—Can you play football?你会踢足球吧?—Yes,I can.是的,我会。/No,I can't.不,我不会。
4.特殊疑问句:特殊疑问词+can+主语+动词原形十其他?
如:What can you do?你会做什么?
句子改写小窍门:改为否定句时,在can后加not,一般缩写为can't。改为一般疑问句时,把can前置到句首,首字母大写,末尾标点改为问号。
