典型例題

① ---Could I borrow your dictionary?

　 ---Yes, of course, you____.　

　 A. might　B. will　 C. can　 D. should

答案C。 could表示語氣的委婉，并不表示時態(tài)。答語中的of course，表示語氣的肯定，允許某人做某事時，用can和 may來表達，不能用could或might。

[注意] will 與you連用，用來提出要求或下命令。should與you 連用，用來提出勸告。

答案A。needn't 不必，不用。 wouldn't 將不, 不會的。 mustn't 禁止、不能。 shouldn't　不應(yīng)該。本題為不需要，不必的意思，應(yīng)用needn't。

情態(tài)動詞基礎(chǔ)訓(xùn)練

6. 用作情態(tài)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(tài)動詞。例如：

① The soldier would sooner die than surrender. 　 那士兵寧死不屈。

② I’d rather walk than take a bus. 　 　我寧愿步行也不愿乘車。

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。

[注意]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(dǎo)的從句，that常省去，從句要用虛擬語氣。對現(xiàn)在和將來的假設(shè)用過去時，對過去的假設(shè)用過去完成時。例如

① I would rather you came on Sunday. 　 我寧可你星期天來。

② I would sooner he hadn’t asked 　 但愿他沒問。

used to +v意為“過去常常”，“過去一直”；be used to +v-ing / 　n(名詞)意為“習(xí)慣于”；be used to +v意為“被用來(做某事)”。

used to只表示過去，而be used to +v-ing / n可表示現(xiàn)在、過去或?qū)�來。例如�?/p>

① He used to smoke. Now he doesn’t. 　 他過去吸煙，現(xiàn)在不吸了。

② He’s quite used to hard work / working hard. 　 他習(xí)慣于埋頭苦干。
