高三英语语法精讲精练习题14
虚拟语气
注意：(1)若条件句中有were，had，should，可把if 省略，而把were，had，should 放在主语前，形成倒装结构，这种结构主要用于书面语中。
Had you taken my advice，you wouldn’t have failed in the examination.如果你听了我的建议，你就不会考试不及格了。
(2)有时主句和虚拟条件从句的动作发生的时间不一致，此时，主句和从句的谓语动词要根据各自所指的不同时间选择适当的动词形式。If you had worked hard，you would be very tired now.
如果你真的努力工作了，你现在就会感到很累的。(从句指过去，主句指现在)
(3)有时虚拟条件并不通过条件从句表达出来，而是通过词、短语或上下文暗示，此时句子的时态要依具体情况而定。
Without electricity(＝If there were no electricity)，life would be quite
different today.
如果没有电，今天的生活就会完全不同。
But for your help，it would have caused a serious loss.
要不是你的帮助，那将会导致巨大的损失。
I was busy that day.Otherwise I would have gone there with them.(If I hadn’t been busy that day，I would have gone there with them.)我那天很忙，否则，我就和他们一起去那儿了。
1.(2010·湖南卷)If he________my advice，he wou ldn’t have lost his job. A．followed B．should follow
C．had followed D．would follow
解析：句意为：如果他(当时)接受我的建议，就不会丢掉他的工作了。本题考查虚拟语气。因为if条件句表示与过去事实相反，故采用过去完成时。
答案： C
2．(2011·厦门市质量检查)—Thank you for reminding me of the time，or I ________late yesterday.
—Don’t mention it.
A．should be B．would be
C．will have been D．would have been
解析：考查虚拟语气。从语境可知说话人是在谈论昨天的事，因此要使用情态动词would＋完成式。谢谢你提醒我时间，不然昨天我就迟到了。
答案： D
3．(2011·山东潍坊质检)________more careful，the mistake would not have been made.
A．If he is B．Had he been
C．Should he be D．If he has been
解析：从主句中的would not have been made 可知，这是与过去相反的虚拟语气，因此从句谓语动词用had been 的形式，又因助动词为had时，可将if省掉，had提前，故B项正确。
答案： B
(1)在名词性从句中，常用来表示命令、建议、要求、愿望等的词后宾语从句和同位语从句中用虚拟语气，形式为：(should)＋动词原形。常这样用的动词有：advise 劝告，demand 要求，desire 渴望，command 命令，insist 坚持，prefer 宁愿，urge 主张，order 命令，recommend 推荐，request 要求，require 要求，suggest 建议，以及这些词的名词形式。
Jane’s pale face suggested that she was ill，and her parents suggested that she (should)have a medical examination.
简苍白的脸色表明她生病了，她父母建议她做一下医学检查。
(2)wish后面所跟宾语从句中的虚拟语气。
表示对现在情况的虚拟：wish＋主语＋动词过去式或were
表示对过去情况的虚拟：wish＋主语＋had＋过去分词
表示对将来情况的虚拟：wish＋主语＋would＋动词原形
I wish she were here.她在这儿就好了。
I wish you would go with us tomorrow.
但愿你明天跟我们一块去。

1.(2010·福建卷)Teachers recommend parents________their children under 12 to ride bicycles to school for safety.
A．not allow B．do not allow
C．mustn’t allow D．couldn’t allow
解析：句意为：为了安全起见，老师建议家长不要让12岁以下的孩子骑自行车上学。本题考查虚拟语气用法。recommend，suggest，insist，order，request，advise等表“建议、命令、要求”等意思的动词，后接宾语从句时，宾语从句的谓语动词常用“should＋动词原形”，should 可以省略。
答案： A
2．(2011·山东潍坊质量抽样)The order came that the medical supplies ________to Beijing for the H1N1 flu soon.
A．would be sent B．should send
C．be sent D．must be sent
解析：当表示愿望、请求、建议、命令等意义的动词(如order，suggest，command等)后面接从句时，从句用虚拟语气。从句谓语用should＋do，should可以省略。order后的同位语从句也用虚拟语气，故选C
项。
答案： C
(1)would rather 句型中的虚拟语气表示愿望，意为“宁愿，但愿”。I’d rather we didn’t go to see a film this evening.
我倒希望我们今晚不去看电影。
(2)It is(high/about)time(that)．..句型中的虚拟语气
在句型“It is (high/about)time...”后面也可跟虚拟语气，从句中常用过去式。有时也用“should＋动词原形”，意为“该是……的时候了”。
It is time (that)we went home.我们该回家了。
(3)if only 引导的感叹句中的虚拟语气
在“if only”引导的感叹句中，要求用虚拟语气，表示愿望。用过去时或“would/could＋动词原形”表示与现在或未来事实相反的愿望；用过去完成时表示与过去事实相反的愿望。
If only I had not been ill last week!
要是上周我没病该多好啊！
1.(2010·合肥第三次教学检测)—Sorry，Daddy.I am not getting on well with my studies.
—Well.________you hadn’t wasted so much time playing online games. A．As if B．Even if
C．If only D．Only if
解析：考查虚拟语气。句意为：——爸爸，对不起，我的学习情况不太好。——哦，要是你不把那么多的时间浪费在网络游戏上就好了。
if only(但愿)接虚拟语气，表示对过去情况的假设。as if好像，even if 即使，only if只有，都是状语从句的连词，不符合语意。
答案： C
2. (2011·青岛一模)—My uncle suggests I________abroad.
—I would rather you________at home.
A．go；stay B．went；stayed
C．go；stayed D．went；stay
解析：suggest当“建议”讲时，从句中要用虚拟语气，结构是“should ＋动词原形”，should可以省略。would rather后面跟从句时，从句中也要用虚拟语气，根据语境此处应用过去时。
答案： C
1．(2010·浙江卷)Had I known about this computer program，a huge amount of time and energy________.
A．would have been saved B．had been saved
C．will be saved D．was saved
解析：句意为：如果我了解这种电脑程序的话，就可以节约大量的时间和精力。本题考查虚拟语气。如果表示与过去事实相反的话，条件句采用过去完成时态(如果省略if可采用部分倒装结构)，主句谓语动词应采用“would＋have＋过去分词”的结构，故答案为A项。
答案： A
2．(2010·陕西卷)If we________the other road，we might have arrived here in time for the meeting.
A．take B．had taken
C．took D．have taken
解析：句意为：如果我们走另一条路，我们可能早就按时到会了。本题考查的是虚拟语气。根据句意及后边主句谓语might have arrived 可知if 从句表示与过去事实相反，故if从句的谓语动词用过去完成时。
答案： B
3．(2010·北京卷)—The weather has been very hot and dry.
—Yes.If it had rained even a drop，things would be much better now！And my vegetables________.
A．wouldn’t die B．didn’t die
C．hadn’t died D．wouldn’t have died
解析：句意为：——现在天气变得又热又干。——是啊。如果当初下一点雨，现在情况也会好很多！我的蔬菜也就不会死了。本题考查虚拟语气。题干中If引导的从句为过去完成时，是对过去事情的虚拟，主句却是would do，对现在事实的虚拟，此为干扰部分，考生须分析清楚句意，空格处表示蔬菜都死了，是过去的事实，在对过去的事实进行虚拟，故选择D项。
答案： D
4．(2009·福建卷)But for the help of my English teacher，I________the first prize in the English Writing Competition.
A．would not win B．would not have won
C．would win D．would have won
解析：本题考查虚拟语气用法。句意为：要没有我英语老师的帮助，我不会在英语写作比赛中获得第一名。本题考查虚拟语气用法，根据句意，可知主句应该使用否定式，而本句是与过去事实相反的虚拟语气，故答案为B项。
答案： B
5. (2009·浙江卷)The doctor recommended that you________swim after eating a large meal.
A．wouldn’t B．couldn’t
C．needn’t D．shouldn’t
解析：句意为：医生建议你不应该在饱餐之后游泳。recommend 后的宾语从句应用虚拟语气，谓语动词为“(should)＋do”，故选D。答案： D
6. (2009·安徽卷)But for their help，we________the program in time. A．can not finish B．will not finish
C．had not finished D．could not have finished
解析：句意为：如果不是他们的帮助，我们就不能及时完成这个项目。根据句意，选用could not have finished表示与过去相反。
答案： D
7. (2009·天津卷)This printer is of good quality.If it______break down within the first year，we would repair it at our expense.
A．would B．should
C．could D．might
解析：句意为：这台打印机质量很好。如果第一年使用坏了，我们保修。虚拟语气中表示将来时间的条件句有三种，就此句而言，应为：If it broke down/If it were to break down/If it should break down。
答案： B
8. (2007·全国卷Ⅱ)________he had not hurt his leg，John would have won the race.
A．If B．Since
C．Though D．When
解析：考查与过去情况相反的虚拟语气。从句用if...had done，主句用．..would/could have done...。
答案： A
9. (2007·山东卷)They ________ two free tickets to Canada，otherwise they’d never have been able to afford to go.
A．had got B．got
C．have got D．get

答案： B
10. (2007·全国卷Ⅰ)Eliza remembers everything exactly as if it________yesterday.
A．was happening B．happens
C．has happened D．happened
解析：考查虚拟语气。由as if引导的从句通常用虚拟语气，再结合前面的remembers可知与现在事实相反，因此用一般过去时。
答案： D
1．(2011·天津质检)My suggestion is that you________much meat.
A．wouldn’t take B．shall not take
C．not have D．won’t have
解析：当suggest 或suggestion 为“建议”的意思时，与其有关的从句就要用虚拟语气，即“should＋动词原形”，should 可以省略。
答案： C
2．(2011·安徽芜湖调研)If human beings had been a bit less greedy and cruel，more birds and animals________dying out.
A．ought to avoid B．could have been avoided
C．should have avoided D．might have avoided
解析：句意为：如果人类少点贪婪少点残忍，更多的鸟类和动物就有可能免于灭绝。这里考查的是对过去情况的假设，从句用had done，主句用would/could/might have done。avoid “避免”，其后接doing 时没有被动语态。
答案： D
3．(2011·哈尔滨检测)________anyone call，please tell him I’m not free.
A．Must B．Can
C．May D．Should
解析：本题考查情态动词用法。句意为：如果有人给我打电话，就告诉他我很忙。第一个分句是省略了if 虚拟条件句，补充完整为：If anyone should call，please tell him I’m not free.当if 省略时，句子要倒装，故D项正确。
答案： D

—Oh，what a pity!
A．came B．had come
C．would come D．would have come

主句谓语用should/would/could/might have done，条件句用过去完成时态，答案应选B项。
答案： B
6．(2011·福建龙岩检测)—I didn’t attend the lecture yesterday.
—I________，either，if my mother hadn’t reminded me.
A．wouldn’t B．wouldn’t have
C．didn’t D．hadn’t
解析：考查虚拟语气。从句子中if my mother hadn’t reminded me 知，此处是对过去状况的虚拟，主句应该用should/would/could/might ＋have done结构，从选项中看只有B项合适(I wouldn’t have 是I wouldn’t have attended the lecture的省略)。
答案： B

D．not use；you will see
解析：考查虚拟语气和倒装语序。英语中表示命令、建议或要求的动词或名词后面的从句中通常使用should do形式的虚拟语气，should可以省略。seldom是否定副词，位于句首时，句子要采用部分倒装语序。
答案： B
10. (2010·日照二模)“If I________taking drugs，I would be a successful businessman now，” said the dying heroin addict.

答案： D

different today. 如果没有电，今天的生活就会完全不同。 But for your help，it would have caused a serious loss. 要不是你的帮助，那将会导致巨大的损失。 I was busy that day.Otherwise I would have gone there with them.(If I hadn’t been busy that day，I would have gone there with them.)我那天很忙，否则，我就和他们一起去那儿了。 1.(2010·湖南卷)If he________my advice，he wou ldn’t have lost his job.

2017临沂中考英语复习语法考点精讲真题精炼词形转换..doc
第39课词形转换旦 I --------------------- DI39KE CIXINGZHUANHUAN 学中考考情分析0 一、词形转换题的命题特点 词形转换题是考英语试题常见的题型2—，主要考查学生“识词、记词和用词”的能力。这类试题体现了“词不离句”的特点，要求学生注意单词在句子的确切含义与正确形式，而不是孤立地死记硬背单词。 词形转换题的考查内容既有比较简单的单词变化，又有对知识的综合运用。这些变化主要包插：一是插号内所给单词的词性不变，根据句意，仅在词形上作适当的变化，然后填入空白处。如：名词由单数形式变为复数形式、(单数或复数的)名词所有格，形容词或副词由原级变为比较级或最高级(包括特殊变化)，人称代词由主格变为宾格、物主代词或反身代词, 基数词变为序数词，动词原形变为不定式、动词-ing形式、过去式或过去分词等。另一种是根据句意，对括号内所给单词作词性转换，如：名词变为动词、形容词，形容词变为副词、动词、名词等，把转换后的单词的正确形式填入空白处。如果为了增加试题的难度，我们还可以见到将这两者结合起的考试题型。 二、词形转换题的解题方法 单词形式变化主要有两种：一是词的形、数、式的变化，一是词的派生变化。在判断出词的变化之后还应该进一步审题，看是否需要使用复合的变化形式，这一点是很重要的。 1根据句意确定词性，单词作适当的变换。 做题时根据句子的意思和相关的词类、句法知识，首先确定空白处单词的词性，再把所给的单词变换成相应的形式。例如： Mary orks very _______ (careful) 分析：句填副词形式carefully,因为修饰动词要用副词形式。 2根据句意判断词义，落实单词的正确性。 这时的词语变化主要集在单词的变化上，也就是各种词性的变化和转换。做这类题除了要了解各种词性的变化形式，还有一点十分重要，那就是语感。如果你平时的口语比较好, 朗读比较自然，你通常可以准确地读出答案。女山 It's dangerous to run _______ (cross) the street 分析：填across是根据前面的动词run得岀的，因为通常情况下两个动词原形是不能一起使用的，而且常见到run across the street这种结构。 3形义结合，灵活运用 这类试题要求很高，做题时必须“形” “义”兼顾，根据句子内容，综合运用所学知识, 既要考虑用词的准确，又要考虑词形变换，有时需进行两次变形。如： Some famous _______ (science) are going to give lectures in our university in August 分析：要先变science为scientist,然后根据前面的Some和后面的are将scientist变成复数形式scientists o 三、词形转换题的解题技巧 做好词形转换题，除了掌握正确的答题方法，在平时的学习过程打好基础，练好基本功, 还要掌握以下几点技巧： 技巧一：名词形式变化。名词的形式变化主要有单数、复数、所有格的变化。 仮!1 1: There are many students living at school;the _______ (child) houses are all far from school

His mother told me he was 37 then, but he had 11 of a mind than a baby has. His “12 ” consisted of rough sounds——sounds of pleasure or anger and 13 more. Mrs. West, then about 75, was a strong, capable woman, as she had to be, of course, because Frank 14 on her entirely. He needed all the 15 of a baby.

This cannot be done by him. 2. may和might的用法 ①表示许可。如： You may drive the car. —May/Might I use your pen? —No，you mustn't. ②用于祈使句中表示祝愿。如： May you succeed! ③表示推测、可能(疑问句不能用于此意)。表推测的might并不是指过去时间，而表示比may把握性略小些。如： He may be very busy now. ④用于表示目的或让步状语从句中。如： No matter what difficulties you may come across，you shouldn't give up. 3. will 和would的用法 ①用于各种人称，表示“意志”“意愿”“决心”等。如： I told her to stop crying，but she just would not listen. ②用于第二人称的疑问句，表示说话人向对方提出请求。用would比用will语气更客气。如： Will/Would you please keep the door open? ③表示真理或习惯，意为“惯于，总是”。如： She will listen to music alone in her room for hours. He would get up early when

高考英语语法专题精讲精练-定语从句
语法专题一：定语从句 1. 定语从句的几个基本概念： 1) 先行词：即被定语从句修饰的名次或代词，通常位于定从的前面。 2) 先行词在从句中担当成份：根据不同成份，用相应的关系代词或关系副词。 3) 关系代词：即先行词在定从中作主、宾、表、定。 作主语：指物，则用that, which引导，且不能省略；指人，用that, who引导，不省略。 作宾语：即及物动词宾语和介词宾语：指物，用that, which引导，可省略； 指人，用that, who, whom引导，可省略。 注意：如将介词提到了定从之首，先行词指人，只能用whom; 指物只能用which。 作表语：一般指人、指物皆用that, 可省略。 作定语：指人、指物皆用whose,不省略。 4) 关系副词：即先行词在定从中作状语，指时间用when, 地点用where, 原因用why，亦 可用介词+which替代。 所谓作状语：即先行词不能直接放入从句中，需要有一个介词连接，而从句中却没有这个介词。 5) 非限制性定语从句：即用逗号与主句或先行词分开，用于补充说明。 (1) which: 用于指代先行词（物），或整个主句，不能省略。 (2) who / whom: 用于指代先行词（人），不能省略。 (3) all / some of + which / whom: 用于指代先行词的部分。 (4) as为关系代词，“正如、就像”的意思, 引导定从时可置于句首、句中或句末。 注意：在非限制性定从中，不能用that。 2. 一些特殊用法： 1) 一般只用that引导从句的情况： (1) 限制性定语从句中，当先行词被强调，如被any, every, each, few, little, no, some, the only, the very等修饰时； (2) 先行词是不定代词all, few, little, much, something, nothing, anything等时； (3) 先行词被序数词或形容词的最高级所修饰时； (4) 先行词既有人又有物时； (5) 当句中已有who时，为避免重复。 2) 一般只用which引导从句的情况： (1) 引导非限制性定语从句，指前面的某名词或它前面的整个主句时； (2) 引导介词、介词短语提前的定语从句时； (3）当先行词为集体名词时，着眼于整体，用which；着眼于各个成员，用who； (4) 替代某些固定短语中的指示代词，如this, that等, 引导定从。 3) 由as引导的定语从句的几种常见情况： (1) as引导非限制性定语从句，说明整个主句的内容，和which引导定语从句代替整个 句子的区别是：which不能放在句首，而as则可以；在句中，as有“正如”、“就象” 之意，而which则没有此意； (2）当先行词前有the same，such修饰时，或在“so / as…as”结构中，表示“那样…… 以致”，后用关系代词as引导限制性定语从句； (3) 在such…as结构中，as为关系代词，替代先行词，引导的是定语从句；在such…that 结构中，that为连词，引导的是一个完整的结果状语从句。
高中英语语法专题精讲精练-动名词解析

I found it pleasant walking along the seashore. 在海滩上走真是乐事。 Do you consider it any good trying again? 你认为再试一次有好处吗？ *形容词worth后也可接动名词，作为复合谓语的宾语。 The music is well worth listening to more than once. 这种曲子很值得多听几遍。（2）作介词的宾语 *能接动名词的短语有：think of/about, dream of/about, hear of, prevent/keep/stop…from…, depend on, set about, succeed (in), worry about, burst out,
