初中英语情态动词讲解-练习及答案
情态动词一、考点、热点回顾【词汇辨析】1.sometimes/ some times/sometime/ some time：sometimes：“有时”=at times. He is sometimes late for school.some times：“几次” I have been to Nanjing some times。
sometime：“某一时刻” I bought it sometime last spring。

some time：“一段时间” We have to stay here for some time。
2。
many/ much/ a few/ a little/ few/ little(1）many修饰可数名词，much修饰不可数名词；都表示许多。
例如：许多书许多牛奶（2)a few和a little都表示"有一点儿"，侧重于肯定，相当于"some”，但a few修饰可数名词,a little修饰不可数名词,例如:He has a few friends in London。
———Would you like some coffee？———Yes，just a little.（3）few和little表示”几乎没有”,侧重否定。
few后接可数名词，little后接不可数名词。
例如：He is a strange man. He has few words。
Hurry up, there is little time left。
【固定搭配】加-ingbe busy doing sth.忙于做……eg: Mother is busy cooking.look forward to + doing sth. 期待做……eg: Tom looks forward to seeing his father again。
Thank you for （doing) sth. 为了…感谢你eg：Thank you for your help。
愉快地做某事eg：I had great fun playing in the water.=have a good time doing sth eg: I had a good time playing in the water.have problem/trouble/difficulty （in）doing sth。
做某事有困难eg：I have difficulty finishing my homework in 2 hours.【情态动词】又叫情态助动词.它们具有以下特点：⑴它们必须与其他动词连用，即：情态动词＋动词原形表示说话人对所述动作的看法，如需要、可能、意愿或怀疑等.⑵绝大多数情态动词没有人称和数的变化，即第三人称单数不加—s（以be和have 开头的情态动词短语除外）。
⑶在意义上，情态动词具有“多义性”.例:can既可表示能力,又可表示可能、允许等意义。
【情态动词的基本用法】1。
can的基本用法:⑴表示体力或智力上的能力，即“能够，会”,可与be able to转换。
例：He can speak English. = He is able to speak English.-Can you play basketball?— No，I can’t。
如果表示将来具备的能力，要用will be able to。
例:If I have a good sleep，I will be able to do the problem。
⑵表示许可，主要用于口语，书面语一般用may。
例:-Can we go home now，please?- No, you can’t。
You can only smoke in this room。
You can't keep the library books for more than a month。
⑶表示“可能”，与may同义,但一般用在疑问句中。
例：What can he possibly want？在否定句中，否定形式can't表示推测“不大可能”。
例：Anybody can make mistakes.The news can't be true。
与第一、二人称连用时，还可以就可能的解决问题的方式或可能的行为提出建议.在这里，也可用could使语气婉转。
例：Can / Could we meet again next week？下周我们可以再见面吗？—What shall we do？我们怎么办呢？— We can / could try asking Lucy for help. ——我们可以请露茜帮忙试试看。
You can / could help me with the cooking。
你可以帮我做饭。
2。
may的基本用法：⑴表示“许可"，用can比较口语化。
例：You may / can come if you wish. 如果你想来,你就来。
You may not pick flowers in this park。
本公园内不许摘花.（may not表示按规定不许可,如果用mustn’t则表示说话人不许可.）？我可以在这里抽烟吗？—No，(mustn’t表示明确的禁止。
)⑵肯定句中表示推测，“可能”。
例：It may rain tomorrow。
明天可能会下雨.The news may not be true。
这个消息可能不会是真的.注意：如果例:Can it be true？那会是真的吗？Who can he be? 他究竟是谁呢？⑶【注意】：……？—Yes，/-No，3. must的基本用法:⑴表示必须，强调说话人的主观意志.例：I must go now, or I’ll be late.You must be here by ten o’clock.【注意】：表示“必须“时，must,而不是mustn’t。
也就是：—Must I/we do it now？—Yes，—No，例：—Must I go with them？-No, you.⑵表示推测，一般只用于肯定陈述句，表示非常肯定。
例：She didn’t look at me. She must be angry. 她不朝我看，一定是生气了。
He is good at English. He must know the word. 他英语好，准知道这个词。
You must be Mr。
Jones. 想必您就是琼斯先生吧.4. have to的基本用法：have to可视为情态动词，但它与其他情态动词在用法上稍有不同。
其他情态动词没有人称和数的变化，而have to却有人称和数的变化,要视主语的不同而变化。
例:I / You / We / They have to….He / She / It has to….You don’t have to…。
Does she have to…?意思是“必须，不得不”.和must不同之处：must强调主观需要have to强调客观需要.例：Sorry, I have to leave now. 对不起，现在我得走了.I've got to go to a meeting。
我得去参加一个会议。
Will he have to work deep into the night? 他将不得不工作到深夜吗？5。
need的基本用法:need的基本词义是“需要",它既可作情态动词，又可作实义动词。
⑴ need用作情态动词时，只用于否定句和疑问句.它只有一种形式，后接动词原形。
例：I don’t believe you need worry。
我相信你没有必要焦急.-Need we go so soon？我们需要这么早就去吗？— Yes，we must。
/ No, we needn’t。
是的，必须。
／不，不必.So I needn’t tell him，need I？所以我不需要告诉他,对吧？请比较以下两句话的不同意思：You needn’t buy the coat. 你没有必要买那件外衣。
（你还没买)You needn’t have bought the coat. 你没有必要买这件外衣的。
(而你却买了）【注意】：I/we……？-Yes,you —No，⑵need用作实义动词时，有时态、人称和数的变化。
如果人作主语，一般后接带to的动词不定式。
即如果物作主语，一般后用例如：I need to look up this word in the dictionary。
My watch needs mending/to be mended。
我的手表需要修理了。
We don't need to work today. (= We needn’t work today。
）Does he need to go right now? （= Need he go right now?)6。
had better的基本用法：had bette r常略作’d better。
现代语法认为它是一个助动词，因为它后接不带to的动词不定式。
意思是“最好做某事;还是做某事比较好”。
例:You'd better get some sleep. 你最好睡一会儿。
You’d better not do that again. 你最好别再做那件事。
What had we better do now? 我们现在怎么做才好呢？Hadn’t we better tell her the truth？我们是否最好不告诉她真相？7. could, should，would，might表示推测：①.must多用于肯定句中表示把握性极大的推测,意思为“一定、肯定”。
如: You have worked hard all day。
You must be tired。
你已辛苦工作一整天了，一定累了。
The book must be his。
His name is on the cover。
这本书一定是他的，封面上写着他的名字。
【注意】must不表推测时，在肯定句中意思为“必须(强调内在的职责)",在否定句中意思为“不许、禁止”，以它开头的疑问句否定回答常用needn’t或don’t （doesn’t）have to。
如：We must obey the traffic rules。
我们必须遵守交通规则。
Cars mustn’t be parked here。

情态动词表推测的讲解及练习题
九年级英语表推断语气的解说与练习表推断时，英语中只使用must,may,might,maynot和 can't。
这五个表达的语气挨次递减：神态动词 must,can,could,may,might表推断的用法神态动词中的 must,can,could,may,might都表推断。
此中 must 的可能性最大， can/could次之，may/might 最小。
详细用法以下：1.must的用法（1）表示推断“可能性”时，意思是“必定、准是”，语气较必定，较有掌握。
HemustbeAmerican.=ItiscertainthatheisAmerican他.准是个美国人。
（2）must 表推断只好用于必定句。
假如要表示“必定不、必定不”的意思时，应用 can’t,如咨询某种可能时，应用 can。
Hemustknowmyaddress他.必定知道我的地点。
（必定）Hecan’ tknowmyaddress他.必定不知道我的地点。
（必定不）Canheknowmyaddress?他知道我的地点吗？（咨询可能性）（3） must表示推断时，能够推断此刻/正在发生的动作 /过去发生的动作。
Hemusthaveacarnow（.此刻）他必定有辆小汽车。
Hemustbedoinghisexercisesintheclassroom（正.在进行）他必定在教室里做练习。
Hemusthavefinishedthework（.过去发生）他必定已达成了工作。
注： must表示推断时极少用于未来的状况。
一般不用Hemustcometomorrow可.用It`scertain/I’ msurethathewillcometomorrow.（4）在反意疑问句中，当隶属部分含有表示推断意义的must时，疑问部分的助动词应与must 后面的动词在非推断状况下的用法保持一致。
Hemustbeaworker,isn ’ the?（此刻）他准是个工人，是吗？Itmusthaverainedlastnight,didn（’过tit?去）昨晚必定下雨了，能否是？YoumusthavelearnedEnglishformanyyears,haven’（tyou?达成时）你必定学了很多年英语，是吗？2.can/could的用法（1） can 表示推断“可能性”时，常常用于否认句或疑问句。

He couldn’t cook when he was 18 years old. 他18岁时还不会做饭。
② can表示推测，意为“可能”，在否定句中表示否定的猜测，意为“不可能”，could用于对过去的猜测，can’t be 不可能例如：He could be cooking at this time yesterday. 他昨天这个时候有可能正在做饭。
He can’t be here be cause he has gone to American.他不可能会在这里，因为他已经去美国了。
③ can表示请求语气，coul d的语气更委婉，例如：Can I help you? / Coul d I help you? 有什么我可以为您效吗？拓展：be abl e to=can也为“能够”，用来表示能力（有人称和时态的变化）例如：He is able to d eal with this problem. 他能解决这个问题的。
2.may和 might① may表示请求，might语气更委婉，例如：May I help you?Might I sit here?② may表示肯定的推测，语气比can更弱，might对过去的推测例如：Mary may be doing her homework now.May can be doing her homework now. can表达的推测语气比may更强，更有把握。
情态动词语法讲解及练习题（2）
情态动词语法讲解及练习题(2)情态动词语法讲解：shall1)用于第一人称征求对方的意见，如：What shall I wear on the journey? 我路上穿什么好呢?Shall we dance? 我们跳舞好吗?2)shall 用于第二、三人称时表允诺，警告，命令，威胁(现已少见)，如：She shall get her share. 她可以得到她的一份。
You shall have it back tomorrow.你明天可以将它拿回。
情态动词should一般不应被认为是情态动词shall的过去式，主要用法有：1)用于第一人称疑问句中询问对方的意愿，但语气较委婉温和，如：What should we do now? 我们现在该怎么办?2)表示应该、必须，常与must 换用。
例如：We should (must) master a foreign language at least.我们应当至少掌握一门外语。
3)“should+be+表语”的结构，表示推测或惊奇。
例如：They should be back by now. 他们现在应该回来了吧。
I am sorry that she should be so careless. 我感到遗憾她竟会那样粗心。
4)“should+have+过去分词”的结构，表示过去该做而实际上尚未做的动作或行为;其否定则表示发生了不应该发生的行为。
其同义结构“ought to have +过去分词”,表示过去“早应该”、“本当”之意，语气较强。
例如：I should have thought of that. 这一点我是应当想到的。
(但没想到)They should not have left so soon.他们不应当走得这么早。
(但已走了)5) 在“It is natural (strange, natural, necessary, surprised, impossible, important ) that……”句型中，主语从句中的谓语动词要用should +动词原形”表示“理所当然”、“奇怪”、“必要”、“惊异”等的意思。
