that用法总结
that是英语中十分常见的单词，用法灵活多样，是英语中最常用的词汇之一。正因为它是我们认为自己最熟悉的单词，反而容易忽视它。在英语中，对that的考查包括三个方面：(1)that作指示代词的用法;(2)that作连词引导各类从句时，需要准确辨别从句类型。
一、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：
A.分析句子结构。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.
第一个句子的主句为a lot of fish were lost to sharks，介词短语in the early days of long line fishing作状语，after引导时间状语从句。第二个句子主句是That is no longer a problem, that为代词，because引导原因状语从句。
B.分析that指代。that指代第一句话，“a lot of fish were lost to sharks after they had been hooked”，其中after引导时间状语从句。
C.译文：而且，在使用多钩长线捕鱼的初期，许多鱼被钩住后又被鲨鱼夺走。这不再是一个问题，因为附近的鲨鱼更少了。
二、that作副词表示程度，相当于so
例：It isn’t all that cold.天没有那么冷。
三、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。
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：

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。

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(thing), any(thing), no(thing) 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(包括last, next等)等修饰时，通常用that：

6. 当关系代词在定语从句中用作表语时，通常用that：
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：
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。

(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。

例：That is what he told me.
他就是这么跟我说的。
2.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。)
