提升UKiset成绩,学好Ukiset语法非常关键,Need在句子中可以做“名词;实义动词和情态动词”。尤其是做实义动词和情态动词是,在疑问句和否定句是有不同的形式的。那么下面就为大家讲解这部分知识点。
做情态动词,和所有情态动词一样,疑问句里情态动词提前;否定句里情态动词后加not:
Need I say more?
还需要我多说吗?
Need I remind you that it's Monday?
需要我提醒你今天是星期一吗?
(疑问句中,need大多用实义动词句型,need提前到主语前为数不多)
You needn't stay in the office all day.
你不必整天呆在办公室里。
We needn't worry about the weather.
我们不必担心天气。
You need not have paid for the parcel.
你本不必付包裹的钱。
做实义动词,疑问句和否定句都是加助动词do,does和did:
Did the villagers need to earn money outside in the cities before?
以前村民需要到外面城市里挣钱吗?
Do you need more time to finish it?
你需要更多的时间来完成它吗?
Does the bird need to migrate to the South in the winter?
这种鸟冬天需要迁徙到南方吗?
我们只要看清楚need后面有没有直接跟另一个动词的原形,就能轻松区别了:
need后直接跟了另一动词,need就是情态动词;
He need only tell her his trouble.

他只需要告诉她他的困难。
Did you say that I need come again?
你说我需要再来一次吗?
Every one need walk across the stream because the old bridge is broken.
因为那座旧桥坏了,每个人都需要步行过河。
need后是名词;动词不定式;动名词(比较少,)need是过去式,分词,第三人称单数等,那need就是实义动词。
It’s true that everyone needs money to survive today.
如今每个人都需要钱才能生存。

我们需要在西部种更多的树。
The plant needs watering.
=The plant needs to be watered.
