need既可用作實(shí)義動(dòng)詞，也可用作情態(tài)動(dòng)詞。 一、need用作情態(tài)動(dòng)詞 1．need作為情態(tài)動(dòng)詞，主要用于否定句、疑問句及表示疑問的從句中。 That’s all settled. It needn’t be talked about. 已完全解決，不必談了。 Why need you go today？你為什么今天就得走？,Period Four Grammar：needn’t have done & didn’t need to do,2．回答由need引導(dǎo)的問句時(shí)，肯定回答一般用must，否定回答時(shí)用needn’t。 —Need I come？我需要來嗎？ —Yes，you must.是的，你必須來。(—No，you needn’t.不，你不必來。),二、need用作實(shí)義動(dòng)詞 1．need用作及物動(dòng)詞和不定式及名詞、代詞等連用，可用于各種結(jié)構(gòu)。 Do we need to buy tickets in advance? 我們需要預(yù)先購(gòu)票嗎？ I don’t need your comments. Thank you. 謝謝，我不需要你來評(píng)頭論足。 He needs to win this game to stay in the match. 他得贏下這場(chǎng)比賽以免被淘汰出局。,2．在個(gè)別情況下，need作為及物動(dòng)詞和情態(tài)動(dòng)詞的句子在意思上略有差別。 He doesn’t need to be told. 不必告訴他了(告訴他沒好處)。 He needn’t be told.無需告訴他(他已經(jīng)知道了)。 3．當(dāng)主語(yǔ)為“物”的名詞時(shí)，用need后的動(dòng)詞的主動(dòng)形式表被動(dòng)意義， need doing＝need to be done，用法同want/require。 The floor needs cleaning/to be cleaned. 地板需要打掃了。 The garden doesn’t need watering/to be watered; it rained last night.花園無需澆水，昨晚下雨了。,4．didn’t need to do與needn’t have done (1)didn’t need to do sth表示過去沒有必要干某事。 I didn’t need to go to the bank after all—Mary lent me the money.我終究不必去銀行了——瑪麗借給我錢了。 (2)needn’t have done sth表示“本沒有必要干某事”。即事情已經(jīng)做了，但現(xiàn)在看來沒必要。 You needn’t have worked that late last night. It was harmful to your health. 你昨晚不必工作到那么晚，那對(duì)你的身體沒好處。 He didn’t need to worry. 他不必?fù)?dān)心。(是否擔(dān)心，我們不知道) He needn’t have worried. 他本不必?fù)?dān)心。(不必做的事情已經(jīng)做了),【單項(xiàng)填空】 —John looks sad.
