38、動(dòng)作又發(fā)生在其前因，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)?？梢员皇÷?。1) 實(shí)義動(dòng)詞： need（需要, 要求） need + n. / to do sth2) 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) n
