高三情态动词的用法归纳
![高三情态动词的用法归纳](https://img.taocdn.com/s3/m/e5784d3e10661ed9ad51f35a.png)
高中情态动词的用法考点归纳一.can和could(1)could用来表示请求时,语气委婉,主要用于疑问句,不能用于肯定句,答语应用can(即:could不能用于现在时态的简略答语中)。
如:——Could I use your dictionary?•——Y es, you can.(否定回答可用:No, I’m afraid not.)回答由could引起的问句,仍用can 而不用could。
-Could you wait a few more minutes?-Y es, I can(2)can和be able to辨析can(could)和be able to都可以表示能力,意思上没有区别。
但can只有现在式和过去式,而be able to则有更多的形式。
如:I’ve always wanted to able to speak fluent English.Those bags look really heavy, are you sure you’ll be able to carry them on your own?但是,表示在过去某时的某一场合经过一番努力,终于做成了某事,通常不用could,而用was/were able to来表示。
这时,was/were able to相当于managed to do或succeed in doing。
如:After the accident it was a long time before she was able to walk again.The fire was very big, but most people were able to escape from the building.(3) 惯用形式“cannot …too…”表示“无论怎么……也不(过分)”。
如:Y ou cannot be too careful.你越小心越好。

高考英语新情态动词知识点
![高考英语新情态动词知识点](https://img.taocdn.com/s3/m/adb3d8e2f021dd36a32d7375a417866fb84ac0a5.png)
高考英语新情态动词知识点在高考英语中,情态动词一直是一个重要的语法知识点。
近年来,对于新情态动词的考查也逐渐增多。
新情态动词包括 ought to、have to、be supposed to 等,它们在用法和语义上都有其独特之处。
首先,我们来看看 ought to。
ought to 表示“应该”,语气比 should 稍强。
它常用于表示责任、义务或正确的做法。
例如:“You ought to study harder if you want to get good grades”(如果你想取得好成绩,你应该更努力学习。
)需要注意的是,ought to 的否定形式是 ought not to,疑问形式是将 ought 提前。
接着是 have to。
have to 强调由于外部的客观原因而“不得不”做某事。
它有人称、数和时态的变化。
比如:“I have to go now because it's getting late”(我现在得走了,因为天色已晚。
)“She had to stay athome yesterday because she was ill”(她昨天不得不待在家里,因为她生病了。
)与 must 不同,must 通常表示主观上的“必须”,而 have to 更侧重于客观上的无奈。
再来说说 be supposed to。
这个短语有多种含义,常见的有“应该;被期望”。
“You are supposed to arrive on time”(你应该准时到达。
)它还可以表示“本应;本该”,用来表示某事没有按照预期发生。
例如:“The train was supposed to leave at 9 o'clock, but it's delayed”(火车本该 9 点出发,但晚点了。
)在具体的语境中,这些新情态动词的运用需要我们仔细分辨。
比如,在表达建议时,ought to 可能更合适;在强调客观条件限制时,have to 更为准确;而 be supposed to 则在描述期望和规定方面用得较多。

过去式:was/ were able to将来式: will be able to完成式: have/has been able to(2)can一般指自身具有的能力,而如果要表达将来的能力,一般要用be able to(3) be able to的过去式was/ were able to可表示在过去设法做成了某事,相当于managed to do,而could则无此意义。
要点2:dare意为胆敢,敢于,既可作情态动词,又可作实义动词.(1)dare作情态动词时,没有人称和数的变化,但有过去式dared,后接动词原形,否定式为dare not/daren't,多用于否定句或疑问句。
(2)dare作实义动词时,有时态、人称和数的变化,后接带to的不定式,否定式要在其前加do not或don't。
不定式符号to有时可以省略。
I dare say我想/我敢说…How dare you.?你怎么敢?要点3 have to表示“必须,不得不”,是由于客观情况而“必须”, have to的否定形式don't have to表示“不必”,可用于各种时态中。
