---Yes.Ithinkheoughtto.
表示要均,命令時,語氣由should(應該)、hadbetter最好)、must(必須)漸強。

hadbetterdosth
hadbetternotdosth
Itisprettycold.You'dbetterputonmycoat.

IfIhaveachoice,Ihadsoonernotcontinuemystudiesatthisschool.Iwouldratherstayherethangohome.=Iwouldstayhereratherthangohome.典型例題
----Shallwegoskatingorstayathome?
----Which___do?
A.doyouratherB.wouldyouratherC.willyouratherD.shouldyourather答案B。本題考查情文东詞rather的用法,wouldrather+dosth意為"寧願",本題為疑問句,would提牵,所以選B。
21.11will和would
注意:
1)wouldlike;Wouldliketodo=wantto想要,為固定搭当。
Wouldyouliketogowithme?
2)Willyou…?Wouldyoulike…?表示肯定伊義的請均勸說時,疑問句中一般用some,而不是any。
Wouldyoulikesomecake?
3)否定結構中用will,一般不用would,won'tyou是一種委婉語氣。
Won'tyousitdown?
21.12情文东詞的回答方式
問句肯定回答否定回答
Needyou…?Yes,Imust.No,Ineedn't
Mustyou…?/don'thaveto.
典型例題
1)---CouldIborrowyourdictionary?
---Yes,ofcourse,you____.
A.mightB.willC.canD.should
答案C.could表示委婉的語氣,並不為時文。答語中ofcourse,表示肯定的語氣,允許某人做某事時,用can和may來表達,不能用could或might。複習:will與you連用,用來提出要均或下命令。should與you連用,用來提出勸告。
2)---ShallItellJohnaboutit?
---No,you___.I'vetoldhimalready.
A.needn'tB.wouldn'tC.mustn'tD.shouldn't答案A。needn't不必,不用。wouldn't將不,不會的。mustn't猖止、不能。shouldn't不應該。本題為不需要,不必的意思,應用needn't。
3)---Don'tforgettocometomybirthdaypartytomorrow.---______.
A.Idon'tB.Iwon'tC.Ican'tD.Ihaven't
答案B.will既可當作情文东詞,表請均、建議、也可作為實義东詞表"意願、意志、決心",本題表示決心,選B。

帶to的情文东詞有四個:oughtto,haveto,usedto,beto,如加上havegotto,(=must),beableto,為六個。它們的疑問,否定形式應予以注意:
