情态动词是一种本身有一定的词义，表示说话人的情绪、态度或与语气的动词，但不能单独作谓语，只能和其他动词原形构成谓语。
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。

如：She can swim fast, but I can ’t .她能游得很快，但我不能。
I can see with my eyes. 我用眼睛看。
（2）.表示许可，常在口语中。
如：You can use my dictionary. 你可以用我的字典。
（3）.表示推测，意为“可能”，常用于否定句和疑问句中，此时can ’t 译为“ 不可能”。
如：Can the news be true? 这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can ’t be our teacher. He is on a visit to the Great Wall.不可能。
咱们老师正在游览长城呢。

初中情态动词知识点及习题(附答案)
初中情态动词讲解及练习题情态动词表示语气和态度。
有实际词义，但是没有单复数等词形变化。
后面通常加动词原形中考主要考查can，must，may，need四个情态动词。
除此之外，表示必要性的情态动词还有should，应该，这个语气比must弱，还有易考点：一．比较have to和must：1) 两词都是'必须'的意思，have to表示客观的需要，must 表示说话人主观上的看法，既主观上的必要。
My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。
(客观上需要做这件事)He said that they must work hard.他说他们必须努力工作。
（主观上要做这件事）2) 在否定结构中：don't have to 表示"不必" mustn't表示"禁止"，You don't have to tell him about it. 你不一定要把此事告诉他。
You mustn't tell him about it. 你一定不要把这件事告诉他。
二．肯定句中，表示推测，语气最强的是must，但在否定句和疑问句中，表示怀疑，猜测，要用can’t. （mustn’t禁止，不允许，不能用来表推测；can’t 不可能）There is someone knocking the door. It must be Tom.It can’t be Tom in the classroom. Because he is ill and he doesn’t come to school today.三．情态动词的回答1. 以can开头的一般疑问句，其肯定和否定回答分别用：can和can’t。

初中英语语法情态动词讲解与练习有答案
情态动词在句中放在谓语动词之前，谓语动词前若有助动词，则在助动词之前，疑问句中，情态动词放在主语之前。
I can see you. Come here. 我能看见你，过来吧。
He must have been away. 他一定走了。
What can I do for you? 你要什么How dare you treat us like that! 你怎么敢那样对待我们!三.情态动词的特点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，过去式可以用来表达更加客气、委婉的语气，时态性不强，可用于过去，现在或将来。
我们称之为“功能用法”。
He could be here soon. 他很快就来。
May I come in? 我可以进来吗?May I use your dictionary? 我可以用你的词典吗?You may put on more clothes. 你可以多穿点衣服。
He said he might lend us some money. 他说他可以借给我们一些钱。
may 否定式为 may not, 缩写形式是mayn’t。
might 是may 的过去式，有两种用法，一种表示过去式，一种表示虚拟语气，使语气更加委婉、客气或对可能性的怀疑。
He told me he might be here on time. 他说他能按时间来。
Might I borrow some money now? 我可以借点钱吗?He might be alive. 他可能还活着。
3. must “必须；应该；一定；准是”，表示说话人认为有必要做某事，命令、You needn't have taken it seriously. 这件事情你不必太认真。
5. dare “敢”，多用在否定或疑问句中。
The little girl dare not speak in public. 小女孩不敢在公众面前说话。
初中英语常用语法知识——情态动词知识点复习(含答案解析)
一、选择题1．Let’s ____________ volleyball. That _________ good.A．playing, is B．playing, sounds C．play, sounds D．play, is sound C解析：C【解析】【详解】句意: 让我们打排球吧，听起来不错。
play玩；sound听起来。
根据“Let's”可知这里let's do sth表示让我们做某事，后面跟动词原形，good是一个形容词，前面用系动词，句子叙述一件事实，时态用一般现在时，主语是单数，用第三人称单数形式,故选C。
2．______ talk in the library.A．Don’t B．Not C．Not to A解析：A【解析】【详解】句意：在图书馆不要说话。
此处是祈使句的否定形式，因此在动词原形前加don’t，故为Don’t+动词原形。
故选A。
3．The teacher often says, “ _____ late for school. ”A．Don’t B．Don’t be C．Not D．Doesn’t B解析：B【解析】【详解】句意：老师经常说：“上学不要迟到。
”老师的话是一个祈使句，祈使句的主要动词要用原形，late是形容词，前要加be动词。
祈使句的否定，是在句首加don’t。
故选B。
4．---Be careful, don’t forget to follow your father.---I know that, Mum. One can never be too careful.A．and B．or C．but D．so A解析：A【解析】试题分析：and和，并且；or或者，否则；but但是；so因此。
句意：小心，并且不要忘了跟着你的父亲。
——我知道，妈妈。
一个人不可能永远太过小心。
故选A。
考点：连词辨析点评：连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词。

你必须仔细地写。
——但我现在必须交上它。
考查情态动词。
must必须，表示说话人主观上的看法；have to不得不，必须，强调客观需要。
第一句表示说话人认为对方必须认真写，是主观看法，第二句表示客观需要不得不现在上交，故选C。
2．A解析：A【解析】【详解】句意：请你说大点声好吗？我不能很好地听到你说的话。
考查情态动词辨析。
can't不能，表示不能够；mustn't不许，表禁止；shouldn’t不应该，表劝诫；needn’t无需，表示没必要。
本句表示“不能够”，根据句意语境，可知BCD三项意思都与句意不合，故选A。
3．D解析：D【解析】【分析】【详解】句意：设计者已经尝试了所有可能的方法使机器变轻，所以你不必担心它的重量。
must必须；一定；may可以；可能；can’t不能；不可能；needn’t不必，没有必要。
根据句意The designer has tried every possible way to make the robot light可知，设计者在努力使机器变轻，所以担心是没有必要的。
故应选D。
4．C解析：C【解析】【详解】句意：所有乘客在乘坐飞机前必须经过安全检查。
考查情态动词辨析。
may可以，表许可或请求；can能，表能力或许可；must必须，指一定；need需要，指有必要。
根据句意语境可知，安检强调“必须，一定”，故选C。
5．A解析：A【解析】【详解】句意：——那顶帽子是Bob的吗？——不，那不可能是他的。
他的是蓝色的。
考查情态动词表推测。
can’t 不可能，否定推测；mustn’t 禁止，不表推测；needn’t 不需要；may not 可能不是，表不确定的推测。
根据回答“No”和“His is blue.”可知这里说话者表达完全否定推测，故选A。
【点睛】在情态动词表推测时，很多同学会搞混can’t和mustn’t，认为他们都表示完全否定的推测，在做题时容易误选。
can’t 不可能，表示完全否定的推测，但是mustn’t 禁止，并不用于表推测。
6．D解析：D【解析】【分析】【详解】句意：-我们现在能过马路了吗？-不，我们不能，我们要等到交通灯变绿。
cou ldn’t不能；needn’t不需要，不必；shouldn’t不应该；mustn’t禁止，不要。
根据句意We have to wait until the light turns green可知，在红灯的时候是禁止过马路的，因此这里的语气比较强，故应选D。
7．D解析：D【解析】【分析】【详解】句意：——妈妈，我今天必须完成作业吗?——不，你不必这么做。
明天是星期天，你今天可以休息一下。
考查情态动词辨析。
A. shouldn’t不应该，表建议；B. mustn’t一定不，表禁止；C. can’t不能，表示不允许；D. don’t have to不必，指没有必要。
回答must引起的一般疑问句，如果要作否定回答，一般是用needn’t（不能用mustn’t）或not have to。
根据句意语境，可知选D。
8．A解析：A【解析】【详解】句意：你看起来相当累，你最好停下来好好休息。
短语stop doing sth.表示“停止做某事”；stop to do sth.表示“停下来去做某事”。
根据“You look quite tired.”可知下文是停下来去休息；You'd better+动词原形，表示“你最好做某事”；根据题意，故选A。
9．B解析：B【解析】【详解】句意：从2013年3月23日开始，14岁以下的人禁止单独去迪士尼乐园。
考查情态动词词义辨析。
couldn’t不能；mustn’t禁止，不允许；needn’t不必；mightn’t可能不。
根据题意可知14岁以下的人禁止单独去迪士尼公园，表达一种强制规定，用mustn’t禁止，不允许。
