用that造定语从句
that可以引导名词性从句、定语从句，具体有那些用法呢?以下是小编整理关于从句中that的用法的内容，希望大家喜欢!
从句中that的用法
一、that引导名词性从句时(即主语从句、宾语从句、表语从句、同位语从句),在从句中无具体含义,只起连接作用,而且在从句中也不作任何句子成分.它所引导的从句的句子结构和意义是完整的,而且从句一般是陈述一个事实.
例如:
①That she was able to come made us very happy.
她能来使我们很高兴.
②The news that our team has won the match is true.
我们队赢了这场比赛的消息是真的.
③The reason he didn't come was that he was ill.
他没来的原因是他病了.
当that引导的主语从句或宾语从句太长时,常用it作形式主语或宾语而把that从句放在后面.如:
①It is well—known that the earth is round.
众所周知,地球是圆的.
②We find it necessary that we practise spoken English every day.
我们发现每天练习英语口语很有必要.
注意：
that引导的主语从句,表语从句以及同位语中,that不能省略引导的宾语从句,一般可以省去that,但在下面情况中不能省略——
1.在suggest,order等表示命令、请求、建议等动词后的宾语从句中,不能省;
2.由and或but所连接的两个引导的宾语从句时,第一个从句中的that可以省,第二个从句中的that不能省;
引导的宾语从句,如果从句中还有其他状语从句,引导宾语从句的'that不能省略.
Tell him that if he is at home,I'll call to see him.
二,that引导定语从句要注意以下几点:
1.定语从句中缺主语,修饰人时用who /that,修饰物时用which /that引导.如:
Is this the factory which /that makes TV sets
The man who /that visited our school is from Australia.
2.从句中缺宾语,修饰人时用 who /whom /that或省略引导词;修饰物时用which /that或省略引导词.如:
Gone are the days which /that we spent together in the village.
He is the man who /whom /that I think to be worthy of our praise.
3.用that不用which的七种情况:
①先行词前有形容词最高级或序数词修饰时,用 that不用which引导.如:
This is the best place that I have ever visited.
②先行词为little,much,all,none,few,(the)one,something,everything,nothing,anything等不定代词时,用that引导.如:
There is nothing in the world that can frighten him.
③先行词既有指人的名词又有指物的名词时,用 that引导.如:
He told us about the people and the cities that he had visited.
④先行词前有any,all,no,few,every,some,little,much,(the)very,(the)only,(the)last等词修饰时,用 that引导.如:
This is the very coat that I need.
⑤先行词为which时,为了避免重复,用that引导.如:
Which is the book that you bought yesterday
⑥先行词在从句中作表语时,常用that引导.如:
Shanghai is no longer the city that it used to be in the 1930's.
⑦当主句是There be...句型时,用that引导.
There are two tickets for the film that are for you two.
定语从句中的that和which用法区别
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。
其次，记得以下只能用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。
如：
Please tell me anything that you know about the matter.
有关此事，凡是你所知道的请告诉我。
2. 当先行词被any, few, little, no, all, much, some等词修饰时。
如：You can take any seat that is free.
任何空着的座位你都可以坐。
3. 当先行词为序数词或被序数词所修饰时。
如：
This is the fourth film that has been shown in our school this term.
这是我们校本学期放映的第四部电影。
4. 当先行词为形容词最高级或被形容词最高级修饰时。
如：
This is the most interesting story book that I have ever read.
这是我读过的一本最有趣的故事书。
5. 当先行词被the very, the only, the last, the just, the same等修饰时。
如：
The only thing that we could do was to wait.
我们唯一能做的事就是等待。
注意：先行词被the same修饰时，关系代词也可用as。
如：I need the same book that / as you have.
我需要有你一样的书。
6. 当先行词既包含人又包含物时。
如： They are talking of the heroines and their deeds that interest them.
他们正在谈论他们感兴趣的女英雄及她们的事迹。
7. 当先行词是疑问代词who，which，what或主句以这些词开头时。
如：
Who that has ever worked together with him doesn’t admire him?
曾经和他一起工作过的谁不钦佩他?
8. 当先行词为主句表语或关系代词为从句表语时。
如：
Our school is no longer the place that it used to be.
我们的学校现在已不是过去的那个样子了。
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。
如：
I did't remember the exact time (when/that) I arrived in Shanghai last month.
我不记得上个月到达上海的确切时间了。
最后，请注意以下几种只能使用which的情况:
1. 在“介词+关系代词”结构中，关系代词必须用which。
如：
This is the reference book of which the teacher is speaking.
这就是老师正在谈及的那本参考书。
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， 例如：
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.
这就是我们已经多次讨论过的问题。
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。
如：You should grasp well those skills which may be used in the future work.
你应该掌握好这些可以用到未来工作中的技能。
最后，记得这个特殊情况吧：当先行词是表示原因或方式的名词时，可以用that引导定语从句，相当于介词+which，that可以省略。
如：
He didn’t like the way that (=in which) she speaks to his mother.
他不喜欢她对他的母亲那样说话。
Imagine the speed that (=at which) he drives the car.
很难想象，他开车开得那么快。
