I haven't 答案B. will既可當(dāng)作情態(tài)動詞.表請求.建議.也可作為實義動詞表"意愿.意志.決心".本題表示決心.選B. 13 帶to 的情態(tài)動詞 帶to 的情態(tài)動詞有四個:ought to, have to, used to, be to, 如加上have got to ,, be able to.為六個.它們的疑問.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. 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)動詞使用.其他的詞作為實義動詞使用.變疑問.否定時.須有do 等助動詞協(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.由于后句為過去時.告訴秘密的動作又發(fā)生在其前因.此地應(yīng)用過去完成時.但它在情態(tài)動詞 ought to 后.所以用have. 14 比較need和dare 這兩詞既可做實義動詞用.又可做情態(tài)動詞用.作為情態(tài)動詞.兩者都只能用于疑問句.否定句和條件句. need 作實義動詞時后面的不定式必須帶to.而dare作實義動詞用時, 后面的to 時?梢员皇÷. 1) 實義動詞: need need + n. / to do sth 2) 情態(tài)動詞: 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 的被動含義:need, want, require, worth后面接doing也可以表示被動: need doing = need to be done 查看更多
