Answer 1

1、that引导定语从句时，它前面的先行词既可指人也可指物。

2、that在定语从句中可作主语、宾语或表语，作宾语时that可省掉，作主语或者表语时不能省。

3、当关系代词在定语从句中作表语时，先行词不管指人或指物时都只用that。

4、当先行词前有the same 修饰时，如果表示同类不同一时用as，如表示同一人或物时用that。

5、that在从句中不充当任何成份，无意义，仅起连接作用。引导宾语从句中that常可省去，引导主语从句、表语从句和同位语从句时一般不省。

大全： 、that在定语从句中的用法that引导定语从句时，它前面的先行词既可指人也可指物，that在定语从句中可作主语、宾语或表语，作宾语时that可省掉，作主语或者表语时不能省。例：He's the man that(who) lives next door.（作主语，先行词指人还可用who）Is that the address that(which) you sent the telegramto?（作宾语，先行词指物还可用which）.但在下列情况下关系代词that不用which.1）表物在先行词前面有序数词或最高级修饰时例：It's the most expensive book that I have bought.2）当先行词为anything, everything, nothing, all, little,much等时例：All that glitters is not gold.3）表物的先行词前all, every, the only, the very, the last, much,little 等修饰时。例：It's the only storybook that we have read this year.4)先行词既指人又指物时例：They talked about the people and thing that had seenin Britain.5）当关系代词在定语从句中作表语时，先行词不管指人或指物时都只用that。例：1、My typewriter is not the machine that it used to be.2、Dr Smith still talks like the man that he was tenyears ago.6）当先行词前有the same 修饰时，如果表示同类不同一时用as，如表示同一人或物时用that。例：1、I have bought the same dictionary as you did lastweek.我买了一本与你上周买的相同的词典。（指两本相同的词典）2、Tom is my classmate. He studies in the same room thatI study in.汤姆是我的同班同学，他和我在同一个教室学习。（这里指的是同一个教室）。7）当主句是It is the first/second time 时后常用that引导从句而不用when。例：It's the second time that we visited the Great Wall.II.that在名词性从句中的用法that作连词可引导主语从句，宾语从句，表语从句和同位语从句。在这四类从句中，that在从句中不充当任何成份，无意义，仅起连接作用。引导宾语从句中that常可省去，引导主语从句、表语从句和同位语从句时一般不省。一、that在主语从句中的用法that引导主语从句时，常用it作形式主语，把真正的主语从句放在句末，以求句子平稳，也可把that从句直接放在句首，这时that绝对不能省去。如果that引导的主语从句在疑问句中时，必须用it作形式主语。例：1）It was obvious that the driver could not control thecar.(that有时可省)2）That the driver could not control the car wasobvious.(that绝不能省)3）Is it possible that they will finish the project insuch a short time?(必须用it作形式主语)二、that在宾语从旬中的用法1、that引导的从句常作动词宾语，这时that常可省去，如果从句后有宾语补足语时，常用it作形式宾语，把that从句放在句末。例：1)The boy dreamed(that)he was flying to the moon．2)We don't doubt that he's honest．3、They want to make it clear that they are doing aimportant job forUS．2、当主句谓语动词是表示“相信”，“臆测”等动词，如believe，suppose，expect，imagine，think等时其后作宾语的that分句如果带有否定意义通常要将not移至主句，即否定转移。例：I don't think anyone will object to the plan.3、that引导从句除可作介词except等，宾语之外般不可以直接用作其它介词宾语，但可用it作形式宾语，把that从句放在it之后。例1)His composition is very good except that there aresome spelling mistakes．例2)Can you depend on it that they will supply us withany food?三、that在表语从句的用法that引导的从句放在联系动词后作表语，以说明主语的内容。that一般不省，但在非正式文体中时也可省去。例：The fact is that he didn't notice the car until toolate．当主语是reason时，应用that引导表语从句不可用because.例：Tom was late again．The reason is that he had missedthe early bus．四、that在同位语从句中的用法that引导的从句常可放在名词fact，idea，promise，belief，decision，news，problem，word等后面，常用于说明该名词的实际内容，起补充作用，而不是起修饰或限制作用。that在从句中不充当任何成分，无意义。如主句谓语较短时，常可把从句放在句尾，以保持句子平衡。例：1)They had to face the fact that the nearest fillingstation wasthirty kilometers away．2)Word came that our“soldiers had defeated the enemybrave1y．Ⅲ．That在状语从句中的用法l、that引导的从句常可放在表示思想状态或感情色彩的形容词之后作状语，表明原因或理由。例：1)We are glad that we have reaped another bumperharvest．2)We are surprised that she should behave like that．2、that可与so，in order，fo rfear连用引导目的状语从句，这时从句中常含有情态动词could，can，might，should等。例：1)He explained again and again in order that we couldunderstandhim．2)I hid the book for fear that he should see it．3、that可与so，such搭配引导结果状语从句，但要注意它们的用法区别。So(1)adj/adv(2)adj+a/an+单数可数名词+that从句(3)many/few复数可数名词much/tittle不可数名词such(1)a+复数可数名词，不可数名词+that一从句(2)a/an+adj+单数可数名词例：1)He was so tired that he could not walk any farther．2)This is so interesting a book that we all want to readit．3)Such little sheep have eaten so much grass that wecan't believe it．当so such引导短语放在句首时，句子要部分倒装。例：I)So badly was he injured that he had to go to thehospital.2)In such a hurry did he go to school that he forgot tobring his schoolbag．IV．that在强调句式中的用法that可以用于It is／as+被强调部分+that句式中，被强调部分可以是句子的主语，宾语，状语，宾语补足语，但不能是谓语或表语。在强调句子某一部分时，把该部分放在that之前，句子的剩余部分原样放在that之后，一般不作变化。例：I am going to take part in the football match on theplayground next Sunday afternoon．1)强调主语IIt is I that(也可用who)am going to take……2)强调on the playground．It is on the playground that(不能用where)I am……3)强调next Sunday afternoon，It is next Sunday afternoon that I……但在强调not……un句型时，注意not的位置变化例：He didn't realized the importance of English until hewent abroad．It was not until he went abroad that he realized theimportance of English.V．that引导的各从句之间用法区别一、that引导的定语从句与同位语从句的区别that引导的定语从句与同位语从句都放在名词之后，但that引导定语从句时，它代替前面的先行词在从句中作主语，宾语或表语，有一定的意义，定语从句对先行词起修饰或限制的作用，而that在同位语从句中不充当任何成分，无意义，从句主要是说明前面名词的内容。例：1)I heard the news that some foreigners would come toour school(同位语从句，that不充当从句中的任何成分)。2)I hear the news that made mesurprised(定语从句，that在从句中作主语)3)The fact that the earth moves around the sun istrue．(同位语从句)4)The fact that he told us yesterday istrue．(定语从句，that在句中作宾语)二、强调句与主语从句的区别that引导的主语从句可直接放在句首，而强调句不能，把强调句中的It is／wasthat删去剩下的句子位置稍作改变或不变仍为一个完整句子，而主语从句则不能。例：1)It's surprising that Mary should have won the firstplace．2)It's Mary that has won the first place．第一句为主语从句，这里it作形式主语也可把that从句直接放在句首，句子结构也正确。第二句为强调句，如把that后的句子放在句首，则句子结构不正确，如省去It's…，that后句子的剩余部分依然正确，故为强调句。又如：①It's a good idea that“we'll make an experiment inthe lab．②It's a good idea that he has told us．第一句为主语从句，第二句为强调句。三、强调句与定语从句区别比较下列两句It is money that is most needed．This is the money that is most needed．第一句为强调句，其中的that并不是money的后置修饰语，第二句为定语从句，修饰前面的瑚money.又如It is Mary that has won the first place。Mary is the girl that has won the first place．第一句为强调句，第二句为定语从句。定语从句的先行词常是名词词组，很少用人称代词，而在强调句中被强调部分可是人称代词，介词词组，副词词组或从句等。例如1)It was he that stole my bike．2)It was in the street that the accident happened．3)It was when it got dark that he came back．四、强调句与状语从句区别比较下列两句It Was at six o'clock that we got home．It Was six o'clock when we got home．第一句是强调句，强调时间状语，如去掉It Was that剩下句子依然完整。第二句为时间状语从句，it表示时间，译作当我们到家时，已是六点了。如为强调句，去掉it Was that句子不成立，因为six O’clock不能作时间状语。又如：It was on February 12，1809 that Lincoln was born．It was February 12．1809 when Lincolnwas born．第一句为强调句，第二句为状语从句。

Answer 4

一、 定语从句是形容词从句，其作用相当于一个形容词，是用来修饰前面的名词或代词的；同位语从句是名词从句，其作用相当于一个名词，是对前面的名词作进一步解释的。例如：
1． We heard the news that he had told her. 我们听到他对她说的消息。
2． We heard the news that he had won the game. 我们听到消息他赢得了比赛。
例1中的that从句的作用相当于一个形容词，其作用是修饰the news；例2中的that从句的作用相当于一个名词，是对the news的进一步说明。

二、定语从句的引导词在从句中充当一定的成分，可作主语、宾语、状语等；而同位语从句中的引导词在从句只起连接作用，不作任何句子成分。例如：
1. A plane is a machine that can fly.
飞机是一种能飞的机器。
2. The fact that they didn't finish the work has to be faced. 必须面对事实，他们没有完成工作。

例1中的引导词that在从句中充当句子成分，作从句的主语，故为定语从句；例2中的that只起连接作用，引导从句解释fact的内容，不作任何句子成分，故为同位语从句。

三、引导定语从句的关联词在从句中作宾语或状语时，可以省略或被其他词代替；而同位语从句的引导词一般不能省略，更不能被代替。例如：
1. The news that she heard is true. 她听到的消息是真的。
2. The news that she will go abroad is true. 她将出国这消息是真的。
例1是定语从句，that可省略；例2是同位语从句，that不能省略。
3. The reason why he was chosen remains unknown. 他为什么被选上的原因还是不清楚。
4. The idea why he was chosen attracted our attention. 他为什么会被选上，这一想法引起我们的注意。
例3中why引导的是定语从句，why可以被 for which或 that 代替；例4中 why引导的是同位语从句，why 不能省去，也不能被其它词代替。

四、同位语从句与其所修饰的名词之间是一种同位关系，二者之间存在逻辑上的系表关系，可用“主+系+表”结构来表示。例如：
The news that he won the first place is true. 他赢得冠军的那个消息是真的。
上句若用“主+系+表”结构来表示，则是：
The news is that he won the first place. 消息是他赢得了冠军。
意思合理，系表结构成立，故为同位语从句。

五、定语从句所修饰、限定的先行词可以是各类名词，可以有复数形式；而同位语从句一般都与抽象名词同位，一般没有复数形式。例如：
1. The possibilities that she was offered seemed very great.她得到的可能性似乎大些。
2. Her mother was worried about the possibility that her daughter dislike to go to school. 她的母亲很担心，她女儿有可能不喜欢上学。
例1中的possibilities是定语从句的先行词，可用复数形式；例2中的possibility是抽象名词，后接的是同位语从句，一般不用复数形式。

六、由when, why, where引导的定语从句分别修饰或说明表示时间、原因或地点的词，但它们引导的同位语从句一般不和表示时间或地点的词同位。例如：
1. I still remember the day when I first came to Beijing. 我仍然记得初次来北京的那天。
2. I have no idea when she will be back. 我不知道她何时回来。
3. This is the house where I lived two years ago. 这是我两年前住的房子。
4. The question where we shall have a meeting hasn't decided. 我们到什么地方去开会，这个问题没有决定。
例1、3中的when和 where引导的是定语从句，day 和house分别表示时间和地点；例2、4中的when和 where引导的是同位语从句。
如果在定语从句与同位语从句的学习中能把握住上述几种区别，那么在阅读文章时，就会迎刃而解，收到更好的效果。
