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】
would的用法

【答案】A
【解析】
【分析】
【详解】
考查虚拟语气。句意：我们将对我们的计划做最后决定。如果你改变主意，请尽快通知我们。根据语境，此处用虚拟语气，表示与将来相反，从句用should+动词原形，省略if，should提前，陈述句是：If you should change your mind……。故选A。
【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 once.
假若我是你，我就会马上做。
要是我能做此事，我一定会做。
3）If he had seen you yesterday, he would have asked you about it.
→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。
17．The door ________ open, no matter how hard she pushed.

【详解】

19．If we had paid enough attention to the issue of the heavily-overloaded vehicles, the tragedy of the collapse of an overpass in Wuxi _____ avoided.
A．should B．could be C．should have been D．could have been 【答案】D
【解析】
【详解】
考查情态动词用法。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。
【点睛】
情态动词+have done的结构和用法有以下几种：
一、must have done sth.“一定做了某事”。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。
二、can/could have done sth.本来能够做某事，而实际上未做；
1.But we could have done it all so much better. 但是，我们本可以把这一切做得更好。
三、can't/couldn't have done sth.不可能做过某事；
1. We could't have done it without you.
没有你我们办不成这事。
四、ought to/should have done sth.过去本应该做某事而实际上并没有做。
You should have done it when you first saw them blooming this spring. 你应该在今年春天第一次看到它们盛开的时候就挖一些的。
2.Even if it’s something you should have done earlie r in the week or missed a detail on.
甚至你在一个星期前的就提早完成了一件事或者忽略了一个小细节。
20．You _____ be right but I’m going back to check anyway.
A．should B．must C．need D．might
【答案】D
【解析】
【详解】
考查情态动词。句意：你或许是对的，但我还是要回去核对一下。A. should应该；B. must 一定，必须；C. need需要；D. might或许。本题主要考查情态动词表示推测的用法，由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。故选D项。【点睛】
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。

--Yes. He _________ the bad food.
A．wouldn’t eat B．shouldn’t eat
C．wouldn’t have eaten D．shouldn’t have eate n
【答案】D
【解析】
试题分析：句意;--杰克孩子医院吗？--是，他本不应该吃坏的食物的。因为是过去吃了坏食物，所以排除AB，这里的shouldn’t have done表示“过去本不应该做而做了”，wouldn’t have done过去本不会做而做了，所以选D。

考查虚拟语气中的情态动词。句意：真遗憾啊！考虑到他的能力和经验，他也许可以做得更好。can have done较少使用此结构，表示对过去行为的怀疑；用于疑问句时意为“难道真的做了吗”，表示怀疑；need have done需要做某事，实际上却未做（表示虚拟语气）；
must have done一定做了某事（表示对过去发生的事情的肯定推测）；might have done表示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。故D正确。【点睛】
本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事；shouldn’t have done 本不应该做而实际做了。need have done本有必要做某事而没做；needn’t have done本没有必要做某事；注意没有mustn’t have done的形式。

情态动词 一、概述 情态动词表示说话人对某一动作或状态的态度，认为“可能、应当、必要”等等，但本身意义不完全，不能单独作谓语，必须和其他动词一起构成谓语。除ought, used, have后跟不定式外，其他情态动词一律跟动词原形。情态动词主要有：can/could, may/might, must, ought to, used to, need, dare, shall/should, will/would, have to等。 二、基本用法 （一）can和could的用法 1．表示能力，可译为“能，会”。 I can swim. 我会游泳。 Emily can dance well and her mother could dance well when she was young. The cinema can seat 1,000 people. I could not read such an easy book when I was 7 years old. 2．表示允许、许可，常用在口语中。could比can语气上要客气。 --- Could I use your dictionary? 我可以用一下你的字典吗？ ---Yes, go ahead. 可以，用吧。（或Yes, you can. 但不能说Yes, you could.） Could/ Can you tell me how to get to the zoo? 劳驾，你能告诉我怎么去动物园吗？ He asked me whether he could take the book out of the reading room. 3. 表示可能（理论上或是逻辑判断上）。 The temperature can fall to–60℃,that is60℃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．表示推测，可用于肯定句（can罕见）、否定句和疑问句，但更常见于疑问句或否定句。在此种用法中can和could没有时态的区别，只是表示可能性的大小，can表示推测的可能性比could大。 Can he be ill at home? 他会是生病在家吗？ Can the story be true? 这个故事会是真的吗？
情态动词 【知识要点】: 情态动词（Modal verbs）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not. 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。疑问形式是将情态动词提至主语前。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。
【典型例题】: 【专题一】:can和could的用法 【例1】Can you lift this heavy box?(体力) 【解析】表示能力(体力、知识、技能) 【练习】 1.Mary speak three languages.(知识) 2. you skate?(技能) 此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to 则有更多的时态。 I’ll not be able to come this afternoon. 当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。 【例2】 -----Can I go now? ----- Yes, you can. / No, you can’t. 【解析】表示请求和允许。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。 【练习】 ---- I come to see you tomorrow? ---- Yes, you . ----No, you /I’m afraid not. 【例3】Can this be true? 【解析】表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。 【练习】 This be done by him. How this be true? 【专题二】may和might的用法： 【例1】----M ight/ May I smoke in this room? ---- No, you mus tn’t. 【解析】表示请求和允许。might比may语气更委婉,而不是过去式。否定回答时可用can’t或mustn’t,表示“不可以,禁止”。用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。 【练习】 ---- I take this book out of the room? ---- Yes, you . No, you 【例2】May you succeed! 【解析】用于祈使句,表示祝愿。
