情态动词基础训练

6. 用作情态动词的其他短语

would rather, would sooner, would (just) as soon, had rather, had better, had sooner, can not but, may 　(just) as well等可用作情态动词。例如：

② I’d rather walk than take a bus. 　 　我宁愿步行也不愿乘车。

③ If you don’t like to swim, you may just as well stay at home. 　 如果你不想游泳，你也可以呆在家里。

② I would sooner he hadn’t asked 　 但愿他没问。
