would的用法

that ,it ,one 代指前面的名词时的用法
1.one 指代前面出现的可数名词，是泛指。可以和冠词连用，也可以有自己的定语。一般不能用做特指，但和定冠词连用时可以是特指。如： Please show me the cup, the red one on the shelf.
2.It 指代前面提到的单数名词，相当于the one。当one是泛指的时候，指的是同名异物，it是指同一物体.如： ----Do you want the cup ? ---Yes ,I want it.
3.that通常用来代替前面出现的可数名词\不可数名词,主要是用来避免重复。如： The weather of Guangzhou is hotter than that of Beijing.

【点睛】
虚拟语气中的倒装
当虚拟条件句中含有 were，had，should时，可以将if省略，然后将 were，had，should，移至句首：
1）If he should fail, he would kill himself.
→Should he fail, he would kill himself.
万一失败，他就会自杀。
2）If I were you, I would do it at once.
→Were I you, I would do it at onc e.
假若我是你，我就会马上做。
要是我能做此事，我一定会做。

→Had he seen you yesterday, he would have asked you about it.
他昨天要是看到了你，他就会问你这事了。
该小题属于上述的第一种情况。should作为情态动词，有一种特殊的用法：在虚拟条件状语从句中表示与将来事实相反的虚拟语气，可以把should放在句首，即主语前，从而省略从属连词if。原来的表述为：If you should change your mind。故选A。

can / could用于表推测的用法
(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。两者没有时间上的差别，只是could 比 can 更委婉，更不确定。
(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接 be doing 结构；对过去情况作推测，后接动词完成式。
二、 may / might用于表推测的用法
表示推测，两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小。如本题，根据I’m going back to check anyway可知，我对此不确定。由此可知，D项符合题意。(1) 在句型使用方面：两者均可用于肯定句和否定句，但用于疑问句时，may通常不用于句首，但可用于疑问句的句中（如特殊疑问句等），而might尽管可以用于疑问句的句首，但不算普通，通常会改用其他句式（如用could等）。
三、must表示推测的用法
must 表示很有把握的推测，其意为“一定会”“肯定会”，只用于肯定句，一般不用于否定句或疑问句。表示对现在或未来的情况作推测，后接动词原形；表示对过去情况的推测，接动词完成式。

情态动词+ have done结构：
1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句.如：It must have rained last night,for the ground is wet.
2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定.can和could一般用于否定句和疑问句,could的语气较can弱.如：He can't have finished the work so soon.
3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推
测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could.如：They may not have known it beforehand.
4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余.如：I needn't have bought so much wine—only five people came.
5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些.如：
You ought to / should have studied harder.你本应该更努力学习的.（但没有）
He oughtn't to / shouldn't have done that.他本来就不该做那件事.（可是做了）
6.“would ＋ have ＋过去分词”表示对过去的某种情况进行猜测,或本来要做某事却因某种原因未做成,通常用来说明某一情况,但不像用should或ought to那样含有责备之意.如：
I guess the poet would have been about twenty when she wrote her first poem.
Another worker wouldn't have acted like that.
38．—I saw your uncle take a taxi to the airport. Why didn’t you drive him there?
—I __________. But my car ___________ .
A．would; was fixed B．would have; was fixed
C．would have; was being fixed D．did; was being fixed
【答案】C
【解析】
【详解】
考查虚拟语气和动词时态。句意：---我看见你叔叔坐出租车去机场了。你为什么不开车送他去那里呢？---我本来想送他了。但是我的汽车当时正在修理。根据语境可知说话人表示本来想做但是没有做的事情，应该用would have done；而修理汽车是指当他叔叔去机场的时候，表示过去正在进行的动作，故答案选C。
39．—______ you sing and dance at this late hour of the night?
—Sorry, I will stop right now.
A．May B．Shall
C．Will D．Must
【答案】D
【解析】
试题分析：考查情态动词的用法。 May可以，可能 Shall： 用于第一三人称的疑问句，表示说话人征求对方的意见或向对方请示。?用于二三人称的陈述句表示说话人给对方的命令、警告、允诺、威胁或决心等。?用于法律、法规条文、合同等，按规定应该履行的义务等。Will 表示请求或建议；表示意愿或表示现在的习惯D. Must表示“必须”“一定”“偏要”之意。此处must表示“偏要,偏偏”。句意：——你偏要在深夜又唱又跳吗？——很抱歉，我会马上停止。
考点：考查情态动词的用法。
40．—How long shall we wait here?
—The first bus set out earlier than usual today and _____ be here any time, I think.

高中英语情态动词精讲与解析
高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she. The meeting might not start until 5 o'clock. 2）构成疑问式或附加疑问式： Must you leave right now? You have been learning French for 5 years, haven't you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 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

情态动词精品学案 情态动词解读: ①本身有一定的词义，表示说话人的情绪、态度或语气的动词。 ②不能单独作谓语。 ③和其他动词原形构成谓语。 ④谓语动词之前。 ⑤无人称和数的变化。 ⑥否定式构成是在情态动词后面加“not”。 ⑦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。 经典例句： We can be there on time tomorrow. 我们明天能按时去那儿。 May I have your name? 我能知道你的名字吗？ Shall we begin now? 我们现在就开始吗？ How dare you treat us like that! 你怎么敢那样对待我们! We can't carry the heavy box. 我们搬不动那箱子。 情态动词考点： 1.情态动词表示推测。 2.情态动词的基本用法。 3.情态动词的答语。 1 / 17
常见情态动词： 情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词的基本用法： 一、can, could 1) 表示能力（体力、知识、技能）时，等于be able to 。 a)Can you lift this heavy box?（体力） b)Are you able to lift this heavy box? c)Mary can speak three languages.（知识） d)Is Mary able to speak three languages? e)Can you skate?（技能） 此时可用be able to代替。 2) can表示请求和允许。 -----Can I go now? ----- Yes, you can. / No, you can’t. 此时可与may互换。在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。（特别注明：这是在表示请求和允许的时候。） ---- Could I come to see you tomorrow? ---- Yes, you can. (No, I’m afraid not. ) can't在否定句中可以表示命令，不允许，但是语气比mustn't弱，具有劝慰的意思. 3)can表示“有时会”： A kind person can lose temper sometimes. 4）表示与五种感官和知觉的动词连用。 I can hear/ see you clearly from here. You can imagine how annoyed she was ! 2 / 17
高中英语情态动词讲解与练习(含答案)
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 to ②可做情态动词又可做实义动词：need,dare ③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 to ⑤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℃。 t) have enough money for a new car. 他不可能有足够的钱买新车。 He can′ t (couldn′ re walking around in the wood. You could start a fire. You mustn′ t smoke while you′

A．can B．should C．need D．might 【答案】B 【解析】 【详解】 考查情态动词。句意：看！你的作文里有那么多的错误。你本应该把所有的注意力都集中在它上面的。表示“本应该做但实际上没有做”应该用should have done结构，can have done 表示可能；need表示需要；might have done表示可能做过某事；故选B。 2．Most of the top leaders expressed a common desire at the UN conference, ______ that different cultures ______ coexist with tolerance. A．the one ; must B．the one ; should C．one ; must D．one ; should 【答案】D 【解析】 【详解】 考查替代和情态动词。句意：大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。替代表泛指的单数名词，通常用one替代。此处用one替代前面的a desire，是同位语；结合句意第二空用情态动词should“应该”。故选D。【点睛】 that ,it ,one 代指前面的名词时的用法 1.one 指代前面出现的可数名词，是泛指。可以和冠词连用，也可以有自己的定语。一般不能用做特指，但和定冠词连用时可以是特指。如： Please show me the cup, the red one on the shelf. 2.It 指代前面提到的单数名词，相当于the one。当one是泛指的时候，指的是同名异物，it是指同一物体.如： ----Do you want the cup ? ---Yes ,I want it. 3.that通常用来代替前面出现的可数名词\不可数名词,主要是用来避免重复。如： The weather of Guangzhou is hotter than that of Beijing. 3．Paul did a great job in the speech contest.
