语法:情态动词can
情态动词:有一定意义,表示说话人的语气或情态,但不能单独作谓语,只能和其他动词原形一起构成谓语,没有人称和数的变化。否定形式是在情态动词后面加上not 。变一般疑问句要把情态动词提到句子的开头,既:情态动词+主语+动词原形+其他?
用法:
表示能力,“会;能”。 eg: Can you dance? 你会跳舞吗?
表示请求或许可,“可以”。eg: Can I ask you a question? 我可以问你一个问题吗? 表示推测和可能,“可能”。eg: He can be at home.他可能在家里。
含情态动词can 的否定句是在can 后加not 。一般疑问句把can 提到句首,其肯定回答为“Yes,主语+can”;否定回答为:“No,主语+can’t”。
eg: He can’t swim.他不会游泳。
----Can she play chess?
----Yes, she can./ No, she can’t.
