一、 need作實(shí)義動(dòng)詞用時(shí),意為“需要”,它有人稱(chēng)、時(shí)態(tài)和數(shù)的變化,后面可接名詞、代詞、動(dòng)名詞及帶to的動(dòng)詞不定式作賓語(yǔ)。常出現(xiàn)在肯定句、疑問(wèn)句和否定句中。謂語(yǔ)動(dòng)詞為need的肯定句,改為否定句和疑問(wèn)句時(shí),要加助動(dòng)詞do的某種形式。例如:
1. I need your help. 我需要你的幫助。
2. Do you need a knife? 你需要小刀嗎?
3. She doesnt need to clean the house today. 今天她不需要打掃房子。
4. You need to take good care of your mother. 你需要好好照顧你的媽媽。
注意: need后跟動(dòng)名詞的主動(dòng)形式可表示被動(dòng)含義,相當(dāng)于need后接動(dòng)詞不定式的被動(dòng)形式。例如:
1. Your car needs repairing. (= Your car needs to be repaired.) 你的汽車(chē)需要修理。
2. The flowers needs watering. (= The flowers need to be watered.) 這些鮮花需要澆水了。
二、 need作情態(tài)動(dòng)詞用時(shí),常出現(xiàn)在疑問(wèn)句和否定句中,其意仍為“需要”,但沒(méi)有人稱(chēng)和數(shù)的變化,后跟動(dòng)詞原形?;卮餹eed引起的一般疑問(wèn)句時(shí),肯定答語(yǔ)中常用must/have to,否定答語(yǔ)中常用neednt。 例如:
1. —Need I write down these words? 我需要把這些單詞寫(xiě)下來(lái)嗎?
—Yes,you must. 是的,你必須寫(xiě)下來(lái)。
2. —Need he come at once? 他需要馬上來(lái)嗎?
—No,he neednt. 不,沒(méi)有必要。
三、 need也可用作名詞,其含意為“需求,需要”。例如:
There is a growing need for college graduates in the countryside. 農(nóng)村需要的大學(xué)畢業(yè)生越來(lái)越多。
There is no need for you to try again. 你不必再?lài)L試了。
need作名詞用時(shí),常見(jiàn)短語(yǔ)有be in need of,意為“需要;缺乏”。例如:
Our school is in needs of a large sum of moneyfor building a library. 我們學(xué)校急需一大筆錢(qián)來(lái)建一座圖書(shū)館。
