小学英语情态动词知识点及练习

情态动词【知识要点】:情态动词(Modal verbs)本身有一定的词义, 表示语气的单词。
但是不能独立作谓语, 只能和动词原形一起构成谓语。
情态动词用在行为动词前, 表示说话人对这一动作或状态的看法或主观设想。
情态动词虽然数量不多, 但用途广泛, 主要有下列: can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not.情态动词无人称和数的变化, 情态动词后面跟的动词须用原形, 否定式构成是在情态动词后面加 "not"。
疑问形式是将情态动词提至主语前。
个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去, 现在或将来。
情态动词属非及物动词, 故没有被动语态。
【典型例题】:【专题一】:can和could的用法【例1】Can you lift this heavy box?(体力)【解析】表示能力(体力、知识、技能)【练习】1.Mary speak three languages.(知识)2... yo.skate?(技能)此时可用be able to代替。
Can只有一般现在时和一般过去式;而be able to 则有更多的时态。
I’ll not be able to come this afternoon.当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。
【例2】-----Can I go now?----.Yes.yo.can..No.yo.can’t.【解析】表示请求和允许。

小升初英语情态动词——need
need(需要)的用法与dare几乎完全相同。
即在否定句或疑问句中,和其他情态动词一样,本身无变化,后面用不带to的动词不定式;在肯定句中时,和实义动词一样,后面的动词不定式要带to,第三人称单数现在大凡时加-s,并有时态的变化。
如:
Need we return the magazines today?我们今天需要把杂志还回去吗?
Every member needs to pay only a little money a year to get medical care.每个成员每年只需缴一点钱就可以得到医疗。
You need not write down your translation. You may do it orally.你们不必写下这个翻译练习,口头做就行了。
[注]与dare一样,在否定句或疑问句里,need也可和实义动词相同,用助动词to do来帮助,后面的动词不定式必须带to。
如:
Do they need to take any tools with them?-No., they don“t need to.他们需要带工具吗? --不需要。
He did not need to go there early that day.那天他不必早去。
need后面有名词作宾语时
完全用作实义动词,表示“需要“或“缺乏“某件事物。
这时,它的变化和大凡实义动词完全相同。
如:
I need a dictionary.我需要字典。
You need a hair-cut.你该理发了。
Do you need a fountain-pen?你需要一支自来水笔吗?
I don“t need a new jacket.我不需要一件新茄克衫。
Mary looks tried,she needs a rest.玛丽看上去累了,需要休息。
Needn“t后加动词不定式(不带to)的完成式时
指过去已做了但勿须做的动作。
如:
You needn“t have watered the vegetables,as it is going to rain.你满可以不必浇菜,天要下雨了。
You needn“t have brought you r umbrella. We are going by taxi你满可以不必带伞,我们要坐出租汽车去。
[注一]注意didn“t have to和didn“t nee to则常表示过去未做也勿须做的动作。
如:I didn“t have to interpret it for her,for she knows Chinese.我勿须为她翻译,她懂汉语。
I didn“t need to take a taxi;it is only five minutes walk to the station.到车站只须走五分钟,我不需要坐出租汽车。
[注二] used to和had better也可看作是情态动词。
情态动词used to表示过去的习惯,但现在已无此习惯(would表过去习惯时则无此含义)。
如:
When I was young,I used to play football.我小时常踢足球。
He didn“t use to come. (或用usedn“t to)他过去不常来。
Did he used to come? (亦可说used he to...?)他过去常来吗?had better表可取,意为“应该“或“最佳“。
如:
We had better go now.我们最佳走吧。
You“d better stop now.你现在应该停下来。
(对长辈不可用had better)
Hadn“t we better go now?我们现在走不好吗?(had better大凡不用于肯定疑问句)。
