7.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：

　　1）The soldier would sooner die than surrender.

　　2）The brave soldier would as soon die as yield to such an enemy.

　　3）I'd rather walk than take a bus.

　　4）If you don't like to swim， you may just as well stay at home.

　　注：这些短语后一般直接跟动词原形。would （had） rather， would （had） sooner， would （just） as soon后可跟that 引导的从句，that 常省去，从句要用虚拟语气。对现在和将来的假设用过去时，对过去的假设用过去完成时。例如：

　　1）I would rather you came on Sunday.

　　2）I would sooner you hadn't asked me to speak yesterday.
