2016年必考英语语法——that与which的用

法区别

两者都可指物，常可互换。其区别主要在于：

1.引导非限制性定语从句时，通常要用which：

The current, which is very rapid, makes the river dangerous. 水流湍急，使这条河很危险。

He has to work on Sundays, which he doesn’t like. 他得在星期天工作，他是不喜欢这样的。

The London team, which played so well last season, has done badly this season. 伦敦队上一个季度打得很好，这个季度却打得很差。

The documents for which they were searching have been recovered. 他们找寻的文件已找到了。

This morning some port wine came, for which I have to thank you. 今天早上送来一些波尔图葡萄酒，为此我得向你道谢。

注：有时“介词+which”引导的定语从句可以转换成“介词+which+不定式”结构：

He had only the long nights in which he could study. =He had only the long nights in which to study. 他只有漫漫长夜可用来学习。

He had a couple of revolvers with which he could defend himself.= He had a couple of revolvers with which to defend himself. 他只有一两把手枪用来自卫。

3.当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every，any，no 等时，通常用that：All that she lacked was training. 她缺的只是训练。

Have you everything that you need? 你需要的东西都有了吗？

The sleeping man’s subconscious mind retained everything that was said around him. 这位酣睡的人头脑的下意识能记住他周围的人说的话。

She would never do anything that was not approved of by her parents. 她父母不赞同的事她绝不会做。

4.当先行词有the very, the only, the same 等修饰时，通常用that：

This is the only example that I know. 我知道的例子只有这一个。

Those are the very words that he used. 那是他的原话。

5.当先行词有形容词最高级或序数词等修饰时，通常用

that：

This is the best dictionary that I’ve ever used. 这是我用过的最好的词典。

6.当关系代词在定语从句中用作表语时，通常用that：

7.当先行词是一个既指人又指物的并列词组时，通常用that：

They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。

8.当要避免重复时：

高中英语语法：It的完整用法精讲 打印版

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

最新定语从句中的that和which的区别

定语从句中的that和which的区别： that和which在从句里都可以做宾语和主语，做宾语时可以省略。在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that，which，还是whom。但是which能引导非限制性定语从句，that则不行。 只能用that的几种情况： 1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。We should do all that is useful to the people. Please tell me anything that you know about the matter. 2. 当先行词被any, few, little, no, all, much, some等词修饰时。 You can take any seat that is free. There is little work that is fit for you. 3. 当先行词为序数词或被序数词所修饰时。 When people talk about the cities of China, the first that comes to my mind is Beijing. This is the fourth film that has been shown in our school this term. 4. 当先行词为形容词最高级或被形容词最高级修饰时。 The best that I could do was to apologize. This is the most interesting story book that I have ever read. 5. 当先行词被the very, the only, the last, the just, the same等修饰时。 This is the very book that I’m looking for. The only thing that we could do was to wait. 注意：先行词被the same修饰时，关系代词也可用as。 I need the same book that / as you have. 6. 当先行词既包含人又包含物时。 They are talking of the heroines and their deeds that interest them. 7. 当先行词是疑问代词who，which，what或主句以这些词开头时。 Who that has ever worked together with him doesn’t admire him? Which is the star that is nearer to the earth？ 8. 当先行词为主句表语或关系代词为从句表语时。 That’s a good book that will help you a lot. Our school is no longer the place that it used to be. 9. 先行词为time时，当time表示次数，引导词用that, 可省略。当表示时间，可用that 或when引导，都可省略。 I do remember the first time(that) I had ever heard the sweetest voice in the world. I did't remember the exact time （when/that）I arrived in Shanghai last month. 只能使用which的情况: 1. 在“介词＋关系代词”结构中，关系代词必须用which。 The house in which we live is very large. This is the reference book（参考书）of which the teacher is speaking. 注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that。 This is the question which/that we’ve had so much discussion about. =This is the question about which we’ve had so much discussion. 2. 先行词为“those＋表事物的复数名词”时，关系代词通常只用which而不用that。 You should grasp well those skills which may be used in the future work.

高中英语语法(全英详细讲解)

必修一 语法点一：Be+v.ing表将来 use the present continuous tense for future plans In English, we have lots of ways of talking about the future. The most common ways of talking about the future we encounter use ‘will’ or ‘be going to’ followed by an infinitive（动词原形）, and we tend to use ‘be going to’ most often for talking about future plans. Sometimes, we also use the present continuous tense to talk about future plans. Ex. ①we are going to Mexico next Sunday. ② Are you coming to the cinema? ③ He is leaving for London in two hours. ④ We are spending next winter in Australia. Only some verbs can be used in this situation, such as: go, arrive, come, leave, start, stay, return, play, have, work, wear, spend, see, meet, etc. 扩展： What’s the difference between using ‘be going to’ and the present continuous to talk about future plans? Let’s look at some more examples: “I’m going to play football on Saturday” You have made a plan in your head but possibly not taken any real action to confirm it. Also, playing football on Saturday is probably not a regular event for you. “I’m playing football on Saturday” You have made a plan and taken some real action to confirm it (e.g. called your friends or booked a place to play). In this case, it’s likely that playing football on Saturdays is a common activity for you. 语法点二：Direct speech and indirect speech(直接引语和间接引语) Let's first define the terms, then look at how to talk about what someone said, and how to convert speech from direct to indirect or vice-versa. You can answer the question What did he say? in two ways: by repeating the words spoken (direct speech) by reporting the words spoken (indirect or reported speech). Direct speech repeats, or quotes, the exact words spoken. When we use direct speech in writing, we place the words spoken between quotation marks (" ") and there is no change in these words. Reported or indirect speech is usually used to talk about the past, so we normally change the tense of the words spoken. We use reporting verbs like 'say', 'tell', 'ask', and we may use the word 'that' to introduce the reported words. Quotation marks are not used. 1、declarative sentence陈述句 ①Change in pronoun:The pronoun (subject) of the reported speech is changed according to the pronoun of reporting verb or object (person) of reporting verb (first part of sentence). Sometimes the pronoun may not change. In following example the pronoun of reported speech is “I” which will be changed

which和that的区别

that与which两者都可指物，常可互换。其区别主要在于： 1. 引导非限制性定语从句时，通常要用which。如：She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请，这是她意想不到的。 2. 直接放在介词后作宾语时，通常要用which。如：The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。 3. much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that。如：There was little that the enemy could do but surrender. 敌人无法,只有投降了。All [Everything] that can be done must be done. 凡能that can be done must be done. 4. 当先行词有the very, the only, the same 等修饰时，通常用that。如：This is the only example that I know. 我知道的例子只有这一个。Those are the very words that he used. 那是他的原话。 5. 当先行词有形容词最高级或序数词(包括last, next等)等修饰时，通常用that。如：。如：This is the best dictionary that I’ve ever used. 这是我用过的最好的词典。The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。 6. 当关系代词在定语从句中用作表语时，通常用that。如：China is not the country (that) it was. 中国已不是过去的中国了。 7. 当先行词是一个既指人又指物的并列词组时，通常用that。如：They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。他们谈论了使他们印象最深的人和事。 8. 当要避免重复时。如：Which is the course that we are to take? 我们选哪门课程？

高中英语语法知识之It的用法总结

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 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 .
