need和dare用法小结

need和dare用法小结

need和dare用法小结最近的一次考试中出现了这么一道题:After the glasses fell to the ground and broke, the little boy his grandma about that.A. dare not tellB. dare not tellingC. dare not to tellD. didn’t dare tell答案选D。

可90%的学生都选了A。

这一现象引起了笔者的关注。

情态动词一直都是高中英语语法中的重难点,而其中的need和dare是难点中的难点。

因为这两个单词有其独特性,它们既可以作情态动词又可以用作实义动词。

学生对此掌握得一直不到位。

笔者根据自己多年的教学经验,现将其归纳如下:一、need(必须、需要)的用法1、need用作情态动词作情态动词,need一般用于否定句、疑问句和条件句中,没有人称和数的变化,也没有时态的变化,后接动词原形。

例如:I needn’t finish my homework today.Need you go now? (请注意回答语:Yes, I must. / No, I needn’t.) *“needn’t have done”表示“本不必做而做了”You needn’t have watered the flowers, because I watered them just now.There is a lot of time left. We needn’t have taken a taxi.2、need用作实义动词作实义动词,need可用于任何句子中,并且有人称、数和时态的变化,后接名词、代词和动词不定式。

例如:I need a new car.We need to finish our homework today.need还有一个特殊的用法:need doing=need to be done (此用法相当于want 和require)例如:The flowers need watering.=The flowers need to be watered. 这些花需要浇水。

这里主要涉及到那几个情态动词的问题.句子中的前部分显然有一个很大的前提,说“MARY的测试成绩在她的班上是最高的”.有这个前提,显然是符合MUST的用意和用法的.因为MUST是“一定,必定”的意思.2. He suggested we go to tomorrow's exhibition together.A. us to goB. we wentC. We shall goD. we go答案是D,,固定结构,suggest sb. to do sth.这里主要涉及到SUGGEST的短语问题.suggest sb. to doing sth suggest sb.doing sth suggest that sb.(should) do sth这里显然是suggest加丛句的问题,一定要记住,它加丛句的时候,其完整形式是:suggest that sb.(should) do sth.中should是可以省掉的,不过后面的动词一定要用回原形.所以这一道题只能选择D.3.

Need/Dare的用法与练习(含答案)
Need的用法
1. need作情态动词
need作情态动词用时,主要用于否定句和疑问句中,形式为need not+原形动词。

(need 辅助后面实义动词,有一定的词义,但不能独立使用)
例:
宾语+ 状语
注意用need 提问时,肯定回答为must,否定回答为needn’t或don’t have to。

例:—Need I finish the work today? (need助动词)
—Yes, you must .是的。

—No. you needn’t /don’t have to. 不,你不必。

2. need作实义动词
作实义动词,need和普通动词一样,有人称、数和时态的变化,后接名词、代词、不定式或动名词做宾语,可用于任何句子。

need肯定陈述句中独立做谓语,而疑问和否定则要借助于do构成。

如:
Do you need a dictionary? 你需要词典吗?
1)如果主语是人,句型如下:sb. need(s) sth. 某人需要某物
sb. need to do sth. 某人需要去做某事
例:I need to pass the exam. 我需要通过这次考试。

He needs to learn English .他需要学习英语。

You need my help.
主语+
2)如果主语为某物
某物需要某种方法处理时,need之后可接不定式短语,但一定为被动语态;也接doing,但一定为主动语态。

句型如下:Sth. need doing 某事需要被做
= need to be done
特别注意两点:
①.主动形式的动名词doing具有被动的含义;也接动名词,但一定为主动语态。

②.该动名词可以改为其动词不定式的被动形式而句子的意义不变。

例如:.
例:The flowers need watering.
= The flowers need to be watered. 这些花需要浇水。

同理:
→The window needs to be fixed.(√正确)
=The window needs fixing.(√正确)
(这窗子需要修理。


The window needs being fixed.(Х错误)
3. 表过去状况时
a. didn’t need to+原形动词表示“当时不必⋯⋯(而且亦未如此做)”,直陈语气
例:He didn’t need to attend the party, so he stayed home.
(当时他不必参加派对,所以就留在家里。


b. need not have+过去分词表示“当时不必⋯⋯(但却如此做)”
例:He needn’t have attended the party, but he went there just the same.
(当时他可以不必参加派对,但他还是去了。


后者也就是虚拟语气:needn't +完成式“表示本来不必做某事而实际上做了某事”。

例:You needn't have waited for me.
4. 注意need在反意疑问句中的变化
a.实义动词,就是一般动词,需要加do/does/did构成。

例:He needs to go, doesn’t he? (needs为动词)
(他需要去,不是吗?)
He doesn’t need to go, does he?
(他不必去,对吧?)
b.情态动词,直接用need构成
例:He need not go, need he? ( need与not连用,情态动词,就是助动词)(他不必去,对吗?)
Dare的用法(语法成分与need相同)
1. dare作情态动词
作情态动词用时, 常用于疑问句、否定句和if/whether从句中, 没有人称和数的变化,但是有过去式(dared),后接动词原形。

例:How dare you say I’m unfair?
He daren’t speak English before such a crowd, dare he?
If we dared not go there that day, we couldn’t get the beautiful flowers.
I wonder whether he dare do it.
反意疑问句中:He daren't speak English before such a crowd, dare he?
2. dare作实义动词
可作实义动词用时,即一般动词,具有人称、时态和数的变化。

在肯定句中,dare后面常接带to的不定式。

在疑问句和否定句中,dare后面可接带to或不带to的不定式。

例:Do you dare to walk in the dark? 你敢黑夜走路吗?
He doesn't dare (to) meet his teacher’s eyes. 他不敢与老师对视。

He dared to go.(当时他敢去。


3. 习惯用法:
a. I daresay + (that)从句我敢说⋯⋯ (daresay是一个词,亦可作dare say)
例:1 daresay he will be late again.(我敢说他又会迟到。


b. How dare + 一般陈述句? ⋯ ⋯怎敢⋯⋯?
例:How dare you say such a thing to me?
(你怎敢在我面前说这种话?)
