that的用法：
标准规则中，that 应只被用于引导限定性（或“确定的”）关系从句， 这些从句用于明确正被谈论的实体；在这种情况下，前面决不能有逗号。因此，我们说杰克建的房子已经拆毁了 ， 在这里，从句杰克所建的 指明哪幢房子被拆毁了， 或者我正在找一本易读的书 ， 在这里，易读的 指明哪类书是需要的。 只有which 用于非限定性（或“不确定的”）从句中， 为已经在上下文中定义的实体提供附加信息；在此用法中，which 之前总有逗号。 因此，我们说化学10班的学生一直在抱怨这课本，实在 （不是 that ) 是太难懂了 。 从句which is hard to follow 并不指明哪一课本被抱怨； 即使它被省略，我们也知道the textbook 指化学10班的课本。 That 象这样用于非限定性从句中， 虽然在写作中曾很普遍而且在口语中依然频繁出现，但在正式文体中最好避免使用。一些语法学家认为对称性要求 which 应只用于非限定性从句中， 就象that 只用于限定性从句中。 因此，他们建议我们应该避免诸如我需要一本关于城市园艺的书 这样的句子， 这里从句which will tell me all about city gardening 指明需要何种书。 当两个或多个关系从句被and 或 or 连接时， which 的这种用法很有用， 如是哲学使普通人找到慰藉并使许多人有理由去称颂。 Which 也用作引导限定性关系从句，在当前置短语中含有that 时， 如我只能给你我不需要的东西 （不是 that that I don't need )或 我们只想分发那本最用的书 （好于that book that will be most helpful )。 当从句主语与从句前短语所指不一致时， that 在关系从句中可以省略。 因此，我们可以说the book that I was reading 或者 the book I was reading 。 在这里，从句主语(I )和短语 the book 的主语不同。 在这些情况下，that 的省略有时被认为是错误的， 但是这在实际中极普遍而且在规范写作中有充分的先例。对于that 用于引导从句时被省略偶然持有异议， 如在我认为我们应该再试一次 中。 但这种用法完全符合语法而且实际上有一些引导这样从句的短语支持；因此，可以正常应用
用法与例句：
I take it she has passed the test
我猜她通过了测验，
27. than I take it that she has passed the test. Thatshould not be omitted, however, when the subordinate clause begins with an adverbial phrase or any element other than the subject:
好于I take it that she has passed the test。 然而，当从句以副词短语开头或其它不是主语的成份开头时，that不能省略：
用法与例句：
She said that under no circumstances would she allow us to skip the meeting.
她说怎么样都会让我们参加会议。
用法与例句：
The book argues that eventually the housing supply will increase.
书中证实住宅供应最终会增加。
28. This last sentence would be ambiguous if that were omitted, since the adverb eventually could then be construed as modifying either argues or will increase. See Usage Note at doubt, this, whatever, which, who
最后一句话中如果that 被省略，句子将变得模棱而可， 因为副词eventually 可以被解释为修饰 argues or will increase 参见 doubt， this， whatever， which， who。
that几种用法？
1.做引导词
2.在句中充当主语或宾语。
that的用法
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。
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
1、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。
That the plates are moving is now beyond dispute. (主语从句)
地球板块是在漂移的，这一事实毋庸置疑。
2、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。
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。
3、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。
She has made such rapid progress that before long she could pass the exam.
她进步很快，不久就能通过考试的。
4、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。
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。
