it、one、that的用法与区别

it/one/that的用法和区别

I. it／one ／that三者均可用作代词, 指代前面提到的名词。一般说来, it 指代同名同物; one与that则指代同名异物。

I have lost my umbrella; I'm looking for it. （该句中it就是指前面的my umbrella）

I have lost my umbrella; I think I must buy one. （one在该句中表泛指, 因为my umbrella已经丢了）

The umbrella you bought is cheaper than that I bought. （替代词that 在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”）II. one与that虽可用来指代同名异物, 但one为泛指, 相当于a／an＋名词; that为特指, 相当于the ＋名词。所以one所指代的名词的修饰语一般为a ／an ／some ／any; that所指代的名词的修饰语往往是the ／this ／that。

A chair made of steel is stronger than one made of wood. （该句中one 可以换成a chair）

The water in the cup is hotter than that in the pot. （该句中that可以换成the water）

III. one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以

代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用those。

I like this pen more than that one. （one代替可数名词单数pen）

There were a few young people and some older ones in the house. （ones代替可数名词复数people）

Mary's handwriting is far better than that of Peter. （that代替不可数名词handwriting）

These pictures are more beautiful than those. （those代替可数名词复数pictures）

IV. one既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the one或the ones代替that或those。

The one ／That on the table is mine. （该句中The one代替事物, 并且也可以用That）

He is the teacher, the one who is loved by the students. （该句中the one代替人, 不能用that）

He advised the farmers to choose the best seed-heads, the ones ／those that had the best color. （该句中the ones代替事物, 并且也可以用those）

V. one一般有前置修饰语, 有时也可有后置修饰语或不用修饰语。而that

不能有前置修饰语, 但可有后置修饰语。

Cook was a strict but good captain, one who took good care of his sailors.

The water in the well is cleaner than that in the river.

VI. it可以替代句中的不定式或从句等, 充当形式主语或形式宾语。one与that均无此用法。

It is known to everybody that the moon travels around the earth once every month.

I found it hard to get on with her.

VII. it与that均可以替代上文全句的内容或部分内容, 而one ／ones则不可以。

He has saved my life; I'll never forget it. （it代替第一分句）

Tom is painting his house. I am told he does it every four years. （it 代替前面分句的部分内容painting his house）

Let's say we meet here at three o'clock. That ought to give you time to buy everything. （That代替前面表述的内容）

英语语法专项：关系代词的用法

关系代词 ?1、关系代词用来引导定语从句。它代表先行词，同时在从句中作一定的句子成分，例如： The girl to whom I spoke is my cousin.跟我讲话的姑娘是我表妹。（该句中whom 既代表先行词the girl，又在从句中作介词to的宾语。） 2、关系代词有主格，宾格和属格之分，并有指人与指物之分。在限定性定语从句中，that 可指人也可指物，见表： ?例如： This is the pencil whose point is broken. 这就是那个折了尖的铅笔。 (whose 指物，在限定性定语从句中作定语) He came back for the book which he had forgotten.他回来取他丢下的书。 （which指物，在限定性定语从句中作宾语，可以省略） ★关系代词的用法 1、关系代词的句法功能 1）关系代词在句中作主语 例如：I prefer music that/which has great lyrics 2）关系代词在句中作宾语 例如：I like music that I can sing along with. 3）关系代词在句中作表语 例如：The house is not the one (that) it used to be. 2、关系代词在从句中作名词的定语 例如：Is she the teacher whose hair is very short? 3、关系代词的用法 1）who和whom的用法：二者都用于指人。Who在定语从句中作主语、宾语，whom 在定语从句中作宾语。Whom在从句中能坐介词的宾语，而who则不能。 例如：I happened to meet the professor (who/whom) I got to know at a party in the shopping center yesterday. 2）whose的用法：一般指人，有时也指物。在定语从句中作定语。 例如：I have got a friend whose brother is training for the Olymoics. 3）which的用法：一般指物，在定语从句中作主语、宾语、偶尔作定语。 例如：The photo which we liked best was taken by Zhao Min. 4）that的用法：指人或物，指人时可与who、whom互换，指物时可与that互换。在从句中可作主语、宾语，还可作表语。

英语中通常使用that

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。

that关系代词用法-定语从句

that常用作关系代词，可指代某人，也可指代某物，指物时有的时候可用which替换that，指人时可用who替换。但在下列情况下，一般用that。 一、that指代某物事时 1.先行词为all, few, little, much, the one, something, anything, everything, nothing等时。如： 2. 先行词被all, every, no, some, any, (a)few, (a)little, much等限定词修饰时。如： 3. 先行词被序数词或形容词最高级修饰时。如： 4. 先行词被the only, the very, the right, the last 等修饰时。如： 5. 先行词是并列结构，既有人又有物时。如： 6. 先行词前有the same 修饰，表示和先行词是同一物时。如： 注：如果表示的是与先行词同一类或相似的某物，则用the same…as….如： 7. 先行词为数词时。

8. 如果which引导的定语从句中又含有一个定语从句，为避免重复，第二个定语从句用that。如： 9. 以which作主语开头的特殊问句，为了避免重复，定语从句用that。如。 10. 关系代词在定语从句中作表语时，而且通常省略。如： 11. 关系代词在there be 句型中作主语时,而且常可以省略。如： 二、that 指代某人时。 1. 泛指某人时。如： 2. 主句是以作主语的who开头的特殊问句，为了避免重复时。如： 3. 先行词前有the same时。如： 4. 关系代词在定语从句中作表语时。如： 另外，that也可用作关系副词，表示时间、地点、原因和方式，在口语中可以用来代替when, where, why 引导的定语从句。在以下名词day, year, time, moment, reason, place等作先行词时，可用that作关系副词引导定语从句。如：

关系代词的用法

关系代词的用法 The Standardization Office was revised on the afternoon of December 13, 2020

关系代词的用法 关系代词在定语从句中做主语，宾语，表语，定语等。常用的关系代词有who ,whom ,whose, that, which, as等 关系代词有三个作用：代替先行词；在定语从句中做句子成分；连接先行词与定语从句 This is an old computer 。it works much slower 这是一台老式电脑。它工作起来速度较慢 This is an old computer which∕ that works much slower 这是一台工作速度较慢的老电脑。 普通代词只起替代作用，如在上例中it替代an old computer ,而关系代词除可以替代an old computer 外，还可以引导定语从句 those who break the rules shall be punished 违反制度的人将会受到惩罚 who∕whom的用法：两者都可指人。Who在定语从句中做主语，宾语，表语，whom在主语从句中做宾语，表语。Women who drink more than two cups of coffee a day have a greater chance of having heart disease than those who don’t 每天喝超过两杯咖啡的妇女与那些不喝这么多的咖啡的妇女相比患心脏病的可能性要大 In this accident ,the number of people who died reached as many as 25 在这次事故中，死亡人数多达25

so-that的用法

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：

语法中that的用法

“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”。

考研语法小知识：that从句用法 一、that作连词引导各类从句 (一)that引导名词性从句 that后面连接一个完整的陈述句，可以位于主语、宾语、表语或同位语的位置，分别引导主语从句、宾语从句、表语从句和同位语从句。此时，that没有实意，而且不在从句中做任何成分。that引导主语从句和同位语从句时不可以省略。 例1：That the plates are movingis now beyond dispute.(主语从句) 地球板块是在漂移的，这一事实毋庸置疑。 例2：The truth isthat everyone should take care of orphan, not just the authorities.(表语从句) 事实是，所有人都应该照顾孤儿，而不仅仅是完全由政府承担。 例3：All people believedthat it was right to rescue the temple.(宾语从句)(注：that可以省略) 所有人都认为拯救古庙是正确的。 例4：The students expressed their hopethat they could be admitted by that university.(同位语从句) 学生们表达了他们向被这所大学录取的愿望。 (二)that引导定语从句 that引导定语从句，在从句中充当主语、表语或者宾语，既可以指代人，也可以指代物。that在定语从句中作宾语时，引导词that可以省略。 例1：The professor that you admire most will visit our university next month. 你敬仰的那个教授下月会到我们学校参观。 例2：This is one of the subways that will be put into use in two years. 这是未来两年内将开通的地铁之一。 例3：I have nothing that is worth reading. 我没有什么值得一读的东西。 (注：当先行词中有不定代词、形容词最高级、序数词或者先行词被the only，the very等限定词修饰等情况下 ，定语从句引导词也只能用that。) (三)that与其他单词结合引导状语从句 that可以和其他单词结构共同引导状语从句，例如such...that，so...that等引导结果状语从句，in order that，so that等引导目的状语从句，in that，now that，on the grounds that等引导原因状语从句 suppose/supposing/assume/assuming/provided/providing that，on condition that等引导条件状语从句等。 例1：She has madesuchrapid progressthatbefore long she could pass the exam. 她进步很快，不久就能通过考试的。 例2：You should make full use of this opportunityso thatyou can get rich experience. 你应该充分利用这次机会，以便获得丰富的经验。 例3：Supposing thatyou were in my position, what would you do? 如果你在我的位置，你会怎么做? 例4：On condition thatyou were lost in the desert, you should ask for help as soon as possible. 如果你在沙漠中迷路，你应该尽早寻求帮助。 (四)that引导强调句 “It is/was+被强调部分+that从句”是高频使用的一种强调句型，其中被强调部分可以作从句的主语、宾语和状语等。强调句中去掉“it is/was”和“that”后，句子成分和语义仍然完整。 例：It was after the war was over that Einstein was able to come back to his research work again. 战争结束后爱因斯坦才能重新进行他的研究工作。 二、that作限定词或代词 that可以作限定词或代词连接名词或名词短语，也可单独使用，用以指代人或者物。此外，that不仅可以指代单独的人或物，还可以指代一句话。 例：Furthermore, in the early days of long line fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now. [2006, text3] 分析：

初中it, one,that,those的用法

I. it／one ／that三者均可用作代词, 指代前面提到的名词。一般说来, it指代同名同物; one 与that则指代同名异物。 I have lost my umbrella; I'm looking for it. （该句中it就是指前面的my umbrella） I have lost my umbrella; I think I must buy one. （one在该句中表泛指, 因为my umbrella 已经丢了） The umbrella you bought is cheaper than that I bought. （替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”） II. one与that虽可用来指代同名异物, 但one为泛指, 相当于a／an＋名词; that为特指, 相当 于the ＋名词。所以one所指代的名词的修饰语一般为 a／an ／some ／any; that所指代的名词的修饰语往往是the ／this ／that。 A chair made of steel is stronger than one made of wood. （该句中one可以换成a chair） The water in the cup is hotter than that in the pot. （该句中that可以换成 the water） III. one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用 those。 I like this pen more than that one. （one代替可数名词单数pen） There were a few young people and some older ones in the house. （ones代替可数名词复数people） Mary's handwriting is far better than that of Peter. （that代替不可数名词 handwriting） These pictures are more beautiful than those. （those代替可数名词复数 pictures） IV. one既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the one或the ones代替that或those。 The one ／That on the table is mine. （该句中The one代替事物, 并且也可以用That） He is the teacher, the one who is loved by the students. （该句中the one代替人, 不能用that） He advised the farmers to choose the best seed-heads, the ones ／those that had the best color. （该句中the ones代替事物, 并且也可以用those） V. one一般有前置修饰语, 有时也可有后置修饰语或不用修饰语。而 that不能有前置修饰语, 但可有后置修饰语。 Cook was a strict but good captain, one who took good care of his sailors.
