2019屆高考英語基礎語法復習
1）they should have been meeting to discuss the problem.
2）he may / might have been buying stamps in the post office when you saw him.
12.used to +v, be used to +v-ing和be used to +v
（1）used to +v意為“過去常常”，“過去一直”；be used to +v-ing / n（名詞）意為“習慣于”；be used to +v意為“被用來（做某事）”。
（2）used to只表示過去，而be used to +v-ing / n可表示現在、過去或將來。例如：
1）he used to smoke. now he doesn’t.
2）he’s quite used to hard work / working hard.
3）the knife is used to cut bread.
13.用作情態動詞的其他短語
would rather, would sooner, would (just) as soon, had rather, had better, had sooner, can not but, may (just) as well等可用作情態動詞。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：這些短語后一般直接跟動詞原形.would (had) rather, would (had) sooner, would (just) as soon后可跟that 引導的從句，that 常省去，從句要用虛擬語氣。對現在和將來的假設用過去時，對過去的假設用過去完成時。例如：
1）i would rather you came on sunday.
2）i would sooner you hadn’t asked me to speak yesterday.
