►情态动词的概念
情态动词用在动词前,表示说话人对该动作或状态的观点,如需要、可能、意愿、怀疑等。常见的情态动词除了本单元学到的can,还有以后我们会学到的may,must,have to,should,would等。
►can的用法
can意为“能;会;可以”,是情态动词,没有人称和数的变化,不能单独作谓语,只能和实义动词原形或be动词原形一起构成谓语。常见用法如下:
①表示某种能力,意为“能;会”。
eg:I can speak English.我会讲英语。
②表示请求或许可,意为“可以”。
eg:You can go with your friends.你可以和你的朋友们一起去。
③表示推测,意为“可能”,常用于否定句或疑问句中。
eg:Tom can't be at home.汤姆不可能在家。
►句子的构成
①肯定句:主语+can+动词原形+其他.
②否定句:主语+cannot/can't+动词原形+其他.
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.
④特殊疑问句:特殊疑问词(组)+一般疑问句?
eg:What can you do?你会做什么?
