18、ke to go with me? 2)Will you…? Would you like…? 表示肯定含義的請(qǐng)求勸說(shuō)時(shí),疑問(wèn)句中一般用some, 而不是any。 Would you like some cake? 3)否定結(jié)構(gòu)中用will,一般不用would, won't you是一種委婉語(yǔ)氣。 Won't you sit down? 12 情態(tài)動(dòng)詞的回答方式 問(wèn)句 肯定回答 否定回答 Need you…?

21、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。 13 帶to 的情態(tài)動(dòng)詞 帶to 的情態(tài)動(dòng)詞有四個(gè):ought to, have to, used to, be to, 如加上have got to ,(=must), be able to,為六個(gè)。它們的疑問(wèn),否定形式應(yīng)予以注意: Do they have to pay their bill before the end of the month? She didn't use to play tennis before she was fourteen.
22、 You ought not to have told her all about it. Ought he to see a heart specialist at once.? ought to 本身作為情態(tài)動(dòng)詞使用。其他的詞作為實(shí)義動(dòng)詞使用,變疑問(wèn),否定時(shí),須有do 等助動(dòng)詞協(xié)助。 典型例題 Tom ought not to ___ me your secret, but he meant no harm. A.have told B.tell C.be telling D. having told 答案A。由于后句為過(guò)去時(shí),告訴秘密的動(dòng)作又發(fā)生在其
23、前因,此地應(yīng)用過(guò)去完成時(shí),但它在情態(tài)動(dòng)詞 ought to 后,所以用 have。 14 比較need和dare 這兩詞既可做實(shí)義動(dòng)詞用,又可做情態(tài)動(dòng)詞用。作為情態(tài)動(dòng)詞,兩者都只能用于疑問(wèn)句,否定句和條件句。 need 作實(shí)義動(dòng)詞時(shí)后面的不定式必須帶to,而dare作實(shí)義動(dòng)詞用時(shí), 后面的to 時(shí)常可以被省略。 1) 實(shí)義動(dòng)詞: need?。ㄐ枰? 要求) need + n. / to do sth 2) 情態(tài)動(dòng)詞: need,只用原形need后加do,否定形式為need not。 Need you go yet? Yes, I must. / No, I needn't. 3) need 的被動(dòng)含義:need, want, require, worth(形容詞)后面接doing也可以表示被動(dòng): need doing = need to be done
