高中英语语法：It的完整用法精讲 it可用作人称代词、指示代词、先行词及引导词等。 1. 人称代词it，是第三人称单数中性，代表前文已提到过的一件事物。如： 1）That vase is valuable. It's more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 2）I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 当说话者不清楚或无必要知道说话对象的性别时，也可用it来表示。如： 3）It's a lovely baby. Is it a boy or a girl? 宝宝真可爱，是男孩还是女孩？ it可用来指代团体。如： 4）The committee has met and it has rejected the proposal. 委员会已开过会，拒绝了这项建议。 it用以代替指示代词this, that.如： 5）--- What's this? --- It's a pen. —这是什么？—是一支钢笔。 6）--- Whose book is that? --- It's Mike's. —那是谁的书？—是迈克的。 2. 指示代词it，常用以指人。如： 7）Go and see who it is. 去看看是谁。 8）--- Who is making such a noise? —是谁发出这样的吵闹声？ --- It must be the children. —一定是孩子们。 3.虚义it无指代性，常用作没有具体意义的主语，出现于表示天气、气候、温度、时间、地点、距离等意义的句子中。如： 9）It is half past three now. 现在是三点半钟。 10）It is six miles to the nearest hospital from here. 这里离最近的医院也有六英里。 11）It was very cold; it snowed and grew dark. 天气很冷；天下着雪，渐渐地变黑了。 it也常用来表示一般的笼统的情况。如： 12）It's awful—I've got so much work I don't know where to start. 糟透了——我有这么多工作要做我不知从何开始。 13）How is it going with you? 你近况如何？ 14）Take it easy. 不要紧张。 it也常用于下列结构： 15）It looks as if the college is very small. 看起来这个学院很小。 16）It seems as though our plan will be perfect. 似乎我们的计划很完善。 17）It's my turn. 该轮到我了。 it也常用于某些习惯用语中作宾语，各该习惯用语有具体意义，但it并无具体意义。如：cab it 乘车catch it 受责，受罚come it 尽自己分内come it strong 做得过分walk it 步行make it 办成take it out of somebody 拿某人出气 4. 先行词it. it充当形式主语或形式宾语，本身无意义，只起一种先行引导的作用，先行词不重读。后面的真正主语或真正宾语通常是不定式结构、-ing分词结构或名词性从句。 （1）用作形式主语

英语中使用that 1.先行词如果有all, every, only, very, any (任何的)，one of few,any,little, no等词修饰时， 2.先行词是不定代词，some（something，somebody，someone），any（anything，anybody，anyone），no（nothing，nobody，no one），every（everything，everybody，everyone 3.先行词有最高级修饰 4.先行词有序数词修饰， 5.先行词如果既有人又有事物 6. 主句以There be…开头,先行词为物时用that,先行词为人的句子中,常用who引导定语从句. . There is a room in the building that is still free. There is a pretty girl who wants to see you. 7. 句子中如果已经有了who，引导词代替人，为了避免重复，要使用that；或者句子中如果已经有了which，引导词代替事物，为了避免重复，要使用that； 8. 先行词如果在主句中做表语，或引导词在从句中做表语，代替事物，多使用that；eg. 这是我昨天买的书。This is the book that I bought yesterday. as作为定语从句引导词的三点用法 （1）代替主句整句话内容； （2）先行词有such修饰，要使用as； eg. He is such a good teacher __as__ we all like. He is such a good teacher __that___ we all like him. (such…that 如此…以至于…,引导结果状语从句)； （3）先行词有the same修饰， the same……as表示同类不同一个：I want to buy the same bicycle as my friend did. the same……that表示同类同一个：The police has found the same bicycle that Jack lost. 引导词代替主句整句话内容，在从句中做主语或宾语，要使用as或which来引导 ?as和which的区别： 1.结构上as的从句既可以放于主句前，也可以放于主句后；which的从句只能放于 主句后； 2.as如果在从句中做主语，谓语动词只能是be动词结构； eg. 她数学考试不及格，这让她的爸爸很生气。
虚拟语气在非真实条件句中 ①错综时间条件句: 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为错综时间条件句，动词的形式要根据它表示的时间作出相应的调整。如： If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。否定句时not留在原来位置不变。如： If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会，我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点，你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话，我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如： What would you do with a million dollars? (=if you had a million dollars)
so...that... 如此……以致于…… ...so that... 以便于，为了 “so...that...”句型的意思是“如此/这么……以致于……”，常引导结果状语从句，但“so...that...”是个爱“变脸”句型，你一不留意就会出错。“so...that...”句型及其转换也是中考的热点，现将其用法总结归纳如下，让我们一起来看看它是怎样变的吧。 一、 so... that...句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj. / adv. + that从句。例如： 1. he is so young that she can't look after herself. 2. The boy ran so fast that I couldn't catch him. 3. He was so angry that he couldn't say a word. / 二、在“such... that...”句型中，such修饰名词，意思也是“如此……以致于……”但当名词前有many、much、(a) few、(a) little等词修饰时，句子中要用“so...that...”而不能用“such...that...”。例如： 1. He has so much money that he can buy what he wanted. 2. I've had so many falls that I have pains here and there. 3. There is little water in the glass that I can't drink any more. 三、 so与that也可连起来写，即变成：... so that ...(以便 / 为了……)，引导目的状语从句。例如： ~ 1. I got up early so that I could catch the early bus. 2. Please open the window so that we can breathe fresh air. 3. You must go now so that you won't be late. 四、以“so...that”引导的结果状语从句可以转换成不定式的简单句，即可转换为“...enough to...”或“...too...to”句型，但这种转换必须符合下列条件： 1. 当主句和从句的主语一致，且that从句是肯定句时，可用“enough to do sth.”来转换。例如：
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下： 第一、that 用作形容词（后接复数名词时用those）。 它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？ 请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气） 第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时） He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough. ②引导主语从句。通常采用it作形式主语的句型。 That the earth goes around the sun is known to everyone. （It is known to everyone that the earth goes around the sun.） ③引导表语从句。 The trouble is that we are short of money. ④引导同位语从句。 引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明： The news that he resigned from office surprised us. The idea that he holds is very common nowadays on campus. 2. that引导状语从句①引导目的状语从句。 Bring it nearer that I may see it better. ②引导结果状语从句。What have I done that he should be so angry with me? ③引导原因状语从句。 I am afraid that I will fail in the driving test. ④引导让步状语从句。意为“虽然、尽管”。
Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) should/ would /could/ might+动词原形 与过去事实相反had + 过去分词 should/ would/could /might + have+过去分词 与将来事实相反1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。
THAT用法总结 第一、that 用作形容词（后接复数名词时用those） 它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？ 请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气） 第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。 .that用来替代前面提到的特指的事物,所代替的名词可以是可数名词,也可以是不可数名词.代替可数名词可以用the one替换.但其前面不可用任何限定词修饰.例如: 1)The population of China is larger than that of Japan.(that代替不可数名词population,不可用the one替换) 2)The headteacher in your class is younger and more active than that in theirs.(that代替可数名词headteacher,可用the one替换) that 代替指物的单数可数名词或抽象不可数名词，一般是特指的 those 代替指人或指物的复数名词，一般是特指的=the ones one 代替指人或指物的单数可数名词，一般是泛指的 ones 代替指人或指物的复数名词，一般是泛指的 That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。 The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。 I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough.
高中英语语法讲解--虚拟语气 1. 语气的定义和种类 （1）语气的定义 语气是动词的一种形式，它表示说话人对某一行为或事情的看法和态度。 （2）语气的种类 A. 陈述语气 表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。 We are not ready. Did it rain all day yesterday? What a fine day today！ B. 祈使语气 表使说话人的建议、请求、邀请、命令等。 Be careful. Don’t forget to clo se the window. Open the door, please. C. 虚拟语气 表使动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。 2. 虚拟语气 一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。如： If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。 虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果主句皆须用虚拟语气。 1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should （would, might，could）+动词原形。 如： If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。 （事实是：天在下雨，我们不能出去野餐。表示愿望。） If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。 （事实是：他没来这，他不可能帮助你。表示对他的良好印象。） 2. 与过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （would, might，could）+ have ＋过去分词。 如：She would have gone to the party if she had been invited.
高考英语语法知识之It 的用法总结 1．It is + 被强调部分+ that ... 该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，状语。强调的主语如果是人，that可以由who换用。 如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was not until + 被强调部分+ that ... 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3．It is clear ( obvious, true, possible,certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定．．．）＂是主语从句最常见的一种结构。 It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉．．．）＂。It is said that he has come to Beijing. 6. It is suggested ( ordered ... ) that ... 主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为＂据建议；有命令．． It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) that ... 该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing ( should ) happen in your class. It is a pity that he is ill. 8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。常译为＂是（正是）．．．的时侯．．．＂。 It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ... ) time that ... 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人第几次做某事了＂。 It is the first time I have been here. = This is the first time I have been here. 10 It is the +形容词最高级+ 名词+ that + ….. 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人做过的最…的事情＂。 This is the best film that I have ever seen . That was the worst song that he had heard . 11. It is .... since ...
虚拟语气(the subjunctive mood,又称假设语气,是谓语动词的一种形式,表示说话人叙述的内容与事实相反,在现实中并不存在,或实现的可能性很小。 一、动词的语气 语气用来区别讲话人对某一行为或事情的看法和态度。英语中的语气(mood有三种,分别是陈述语气、祈使语气和虚拟语气。 1.陈述语气 陈述语气一般用来叙述事实或就事实提出询问,主要用于陈述句、疑问句和某些感叹句。 Where there is a will, there's a way. 有志者事竟成。 Can you help me carry the box upstairs 你能帮我把箱子搬到楼上吗?
