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表示委婉的語(yǔ)氣,并不為時(shí)態(tài)。答語(yǔ)中of course,表示肯定的語(yǔ)氣,允許某人做某事時(shí),用can和 may來(lái)表達(dá),不能用could或might。復(fù)習(xí): will 與you連用,用來(lái)提出要求或下命令。should與you 連用,用來(lái)提出勸告。
2)---Shall I tell John about it?
---No, you ___. I've told him already.
A. needn't
B. wouldn't
C. mustn't
D. shouldn't
答案A。needn't 不必,不用。 wouldn't 將不, 不會(huì)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。
3)---Don't forget to come to my birthday party tomorrow.
---______.
A. I don't
B. I won't
C. I can't
D. I haven't
答案B. will既可當(dāng)作情態(tài)動(dòng)詞,表請(qǐng)求、建議、也可作為實(shí)義動(dòng)詞表"意愿、意志、決心",本題表示決心,選B。
