need
1.情態(tài)動(dòng)詞need
need和dare一樣,作為情態(tài)動(dòng)詞時(shí),主要用于否定句和疑問句,一般不用于肯定句中(在肯定句中常被must, have to, ought to, should等情態(tài)動(dòng)詞取代)。作為情態(tài)動(dòng)詞,它的詞形只有need一種形式。
You needn't return the book now. You can keep it till next week if you like. 你現(xiàn)在不必還書, 如果愿意,你可以下周還。(needn't = don't have to)
Need I hand in my homework now
我現(xiàn)在就要交家庭作業(yè)嗎?
--- Need he finish the article next week
他要下個(gè)星期完成這篇文章嗎?
--- Yes, he must.
是的,他必須完成。
--- No, he needn't.
不,他不需要。(= he doesn't have to)
2.行為動(dòng)詞need
need和dare一樣,也可以作行為動(dòng)詞,可用于肯定句、否定句和疑問句中。行為動(dòng)詞need有人稱和數(shù)的變化。
Plant needs water.
植物需要水。
My shirt needs a button.
我的襯衫需要一枚鈕扣。
My car needs repairing.
我的車該修理了。
He has grown up. We don't need to worry about him.
他已經(jīng)長大了,我們不必為他擔(dān)心。

干那工作,需要耐心。
提示:
Need作為情態(tài)動(dòng)態(tài)時(shí),不要用于肯定句中。
【誤】She need do her homework by herself. (need作為情態(tài)動(dòng)詞時(shí),不用于肯定句中)
【正】She needs to do her homework by herself.
她該獨(dú)立完成家庭作業(yè)。
