高中英语情态动词讲解与练习(含答案),成才系列
高中英语语法之情态动词（一）情态动词的定义：情态动词表示说话人对某一动作或状态的态度。
（二）情态动词的特点：1）有一定词义；2）不受主语人称和数的变化影响；3）与主要动词的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待）。
情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。
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。
He could be here soon. 他很快就来。
We can't carry the heavy box. 我们搬不动那箱子。
I'm sorry I can't help you. 对不起，我帮不上你。
基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想：What have you been doing since? （构成完成进行体，本身无词义）I am afraid I must be going. （一定要）You may have read some account of the matter. （或许已经）除此之外，情态助动词还有如下词法和句法特征：1）除ought和used以外，其他情态动词后面只能接不带to的不定式。
如果我们把ought to 和used to看做是固定词组的话，那么，所有情态动词无一例外地只能接不带to的不定式：We used to grow beautiful roses.I asked if he would come and repair my television set.2）情态助动词在限定动词词组总是位居第一：They need not have been punished so severely. 3）情态助动词用于第三人称单数现在时的时候，没有词形变化，即其词尾无-s形式：She dare not say what she thinks.4）情态动词没有非限定形式，即没有不定式和分词形式，也没有相应的动名词：Still, she needn't have run away.5）情态助动词的“时”的形式并不是时间区别的主要标志。

句意：很抱歉，但是你一定是弄错了。

句意：如果我们对超载车辆问题给予足够的重视，就可以避免无锡立交桥垮塌的悲剧。
本句为“情态动词+have done”结构，结合句意表示“本来可以；本来能够”应用could have done结构，且主语与谓语动词avoid构成被动关系，故应用be done形式。
故选D。

表示对过去事情的较有把握的推测，这时只能用在肯定句中，“肯定/必须已经干过……”，在否定句和疑问句中用can’t或couldn’t或can/ could，例如：1.From what you said, she must have told you all about it. 从你的话看，她一定告诉了你所有的事情。
高中英语 情态动词讲解及练习(有答案)
情态动词讲解及练习一、can和could特别说明：（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?——Yes, you can.(否定回答可用：No, I’m afraid not.)(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：You cannot be too careful.你越小心越好。
惯用形式“cannot but+ 不定式（不带to）”表示“不得不，只好”。
如：I cannot but admire her determination.我不得不钦佩你的决心。

高中英语语法之情态动词（一）情态动词的定义：情态动词表示说话人对某一动作或状态的态度。
（二）情态动词的特点：1）有一定词义；2）不受主语人称和数的变化影响；3）与主要动词的原形（或称不带to 的不定式）一起构成谓语（除ought to 作固定词组看待）。
情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。
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。
He could be here soon. 他很快就来。
We can't carry the heavy box. 我们搬不动那箱子。
I'm sorry I can't help you. 对不起，我帮不上你。
基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想：What have you been doing since? （构成完成进行体，本身无词义）I am afraid I must be going. （一定要）You may have read some account of the matter. （或许已经）除此之外，情态助动词还有如下词法和句法特征：1）除ought 和used 以外，其他情态动词后面只能接不带to 的不定式。
如果我们把ought to 和used to 看做是固定词组的话，那么，所有情态动词无一例外地只能接不带to 的不定式：We used to grow beautiful roses.I asked if he would come and repair my television set.2）情态助动词在限定动词词组总是位居第一：They need not have been punished so severely.3）情态助动词用于第三人称单数现在时的时候，没有词形变化，即其词尾无-s 形式：She dare not say what she thinks.4）情态动词没有非限定形式，即没有不定式和分词形式，也没有相应的动名词：Still, she needn't have run away.5）情态助动词的“时”的形式并不是时间区别的主要标志。
在不少场合，情态助动词的现在时和过去时形式都可以表示现在、过去或将来时间：Would you mind very much if I ask you to do something?She told him he ought not to have done it.6）情态助动词之间是相互排斥的，即在一个限定动词词组中只能出现一个情态助动词，但有时却可以与have 和be 基本助动词连用：You should have washed the wound.Well, you shouldn't be reading a novel.（三）情态动词有四类：①只做情态动词：must,can(could),may(might),ought to②可做情态动词又可做实义动词：need,dare③可做情态动词又可做助动词：shall(should),will(would)④具有情态动词特征：have(had,has) to,used to⑤情态动词表猜测（四）情态动词的基本用法1.can (could)1）表示能力，could 主要指过去时间。
Two eyes can see more than one. 两只眼比一只眼看得清。
Could the girl read before she went to school? 这女孩上学前能识字吗？2）表示可能（理论上或是逻辑判断上）。
The temperature can fall to –60℃, that is 60℃below freezing.气温可降至—60℃，也就是零下60℃。

You mustn´t smoke while you´re walking around in the wood. You could start a fire.在林子里走时勿吸烟，那样可能会引起火灾。
3）表示允许。
Can I have a look at your new pen? 我可以看一看你的新钢笔吗？He asked whether he could take the book out of the reading—room.他问他可不可以把书带出阅览室。
4）表惊异、怀疑、不相信等态度。
主要用于否定句、疑问句或感叹句中。
Where can (could) they have gone to? 他们会去哪儿了呢？He can´t (couldn´t) be over sixty. 他不可能超过六十岁。
How can you be so careless? 你怎么这么粗心？5）比较委婉客气地提出问题或陈述看法。
Can (Could) you lend me a hand? 帮我一把好吗？I´m afraid we couldn´t give you an answer today. 恐怕我们今天不能给你答复。
2.may (might)1）表允许，might 可以指过去时间，也可指现在时间，语气更委婉。
You may take whatever you like. 你喜欢什么就拿什么。
He told me that I might smoke in the room. 他告诉我可以在房间里抽烟。
May (Might) I ask for a photo of your baby? 我可以要一张你宝宝的照片吗？在回答以may 引起的问句时，多避免用这个词，而用其它方式，如Yes, please. / Certainly. / Please don´t ./ You´d better not. / No, you mustn´t.等，以免显得太严峻或不客气。
2）表可能（事实上）。
可以指过去时间，也可以指现在时间，但语气更加不肯定。
He may be at home. 他可能在家。
She may not know about it. 她可能不知道这件事。
He was afraid they might not agree with him. 他担心他们可能不同意他的意见。

He must be ill. He looks so pale. 他准是病了。
他的脸色苍白。
