that从句与what从句
隆回一中唐佐中
that用作连词时，本身无词义。
what用作连接代词时，本身含有疑问意义。
二者都可用来引导从句。
但什么场合用that，什么场合用what，有些同学却容易弄错。
一.引导主语从句
that与what都可引导主语从句。
特点：that在从句中不作句子成分，但不能省掉。
what在从句中可作主语、宾语、表语或宾语补足语，也不能省掉。
例如:
1. What he said at the meeting was very important. 他在会上说的话非常重要。
(What在主语从句中作宾语)
2. What surprised us is that he did it alone. 使我们吃惊的是，他一个人做了那项工作。
(What在主语从句中作主语)
3. That he did it alone surprised us. 他一个人做了那项工作，这使我们吃惊。
(That只是引导主语从句，在从句中不作任何成分)
也可用it作形式主语置于句首，而将that引导的主语从句移至句末。
例如:
It surprised us that he did it alone.
二. 引导宾语从句
that与what都可引导宾语从句。
特点：that在从句中不作句子成分，一般情况下可以省掉，但若句中有两个以上的宾语从句，则只能省掉引导第一个宾语从句的that。
what在从句中可作主语。
宾语。
表语和宾语补足语，而且不能省略。
例如:
1. They stopped to see what was happening. 他们停下来看看面前发生了什么事情。
(what在从句中作主语)
2. The teacher got angry because of what the boy had done. 因为那个男孩子所做的事，老师很生气。
(what在从句中作宾语)
3. The moon and the sun are just part of what we call“universe”. 太阳和月亮正是我们所说的“宇宙”的一部分。
(what在从句中作宾语)
4. All the people believed (that) it was right to rescue the old temple.所有的人都认为拯救古庙是正义之举。
(that在从句中不作句子成分，可以省略)
5. We must believe (that) each of us is able to do something well，and that，when we discovered what this something is，we must work hard at it until we succeed. 我们必须相信我们每个人都可以把一些事情做好，而当我们领悟此事是何事之后，我们就必须努力做下去，直到成功为止。
(第一个that 可省略，第二个that不能省略。
what引导宾语从句时，what不能省略。
)
三. 引导表语从句
that与what都可以引导表语从句。
特点：that在从句中不作任何句子成分，但通常不能省略。
what 在从句中可以作主语。
宾语。
表语和宾语补足语，也不能省掉。
例如:
1. Mary is no longer what she used to be. 玛丽不再是从前那样了。
(what在表语从句中作表语)
2. The question is what we should do to prevent him from going. 问题是我们怎样才能阻止他去。
(what在表语从句中作宾语)
3. The reason why he didn’t come today is that his mother is ill. 他今天没来的原因是他母亲病了。
(that只引导表语从句，不作任何成分)
四. 引导同位语从句
that和what都可以引导同位语从句，对其前面名词的具体内容作详细阐述。
后面常常跟同位语从句的名词有fact，idea，news，hope，belief，promise，thought，suggestion，proposal，truth等。
特点：that在从句中不作句子成分，但不能省略。
what 在从句中可以作主语、宾语、表语和宾语补足语，也不能省略。
例如:
1. I have no idea what we should do next. 我不知道下一步我们该做什么。
(what在同位语从句中作宾语)
2. He made a promise that he would study hard. 他许诺要努力学习。
(that只起引导作用，在从句中不作任何句子成分)
3. The boy expressed his hope that he would be a pilot when he grew up. 那个男孩子希望长大后当一名飞行员。
(that只起引导作用，在从句中不作任何成分)
五. 引导定语从句
特点：that可以引导定语从句，并在定语从句中作主语或宾语，that既可指人也可指物。
that在从句中作宾语时可省略。
what不能引导定语从句。
例如:
1. This is one of the buildings that were built last year. 这是去年建成的楼房之一。
(that在从句中作主语，不能省略)
2. The doctor (that) you met in the street yesterday came here 20 years ago. 你昨天在街上遇到的那位医生二十年前就来到了这里。
(that在从句中作宾语，可以省略)
学生作业本中常常会出现这样的句子:
1. He did all what he could to save the patient.
2. All what he needs is more time.
以上两个句子都是错误的。
两句中的what都应改为that。
that引导的定语从句可修饰先行词all。
也可以直接去掉what。
这样一来，all和he之间是省掉了作宾语的关系代词that。
that引导的定语从句和that引导的同位语从句之间的区别在于: that引导定语从句时，在定语从句中作主语或宾语(作宾语时可省略)。
that引导同位语从句时，在句中不作任何句子成分，但也不能省略。
六. 引导状语从句
so ... that，such ... that和so that可引导状语从句。
what不能引导状语从句，但whatever; no matter what可引导让步状语从句。
例如:
1. He made such rapid progress in English that before long he could write articles for an American newspaper. 他在英语上取得了如此快的进步，不久就能为美国的一家报社写文章了。
2. Put the little plants in the shade so that the sun won’t burn them. 请把幼苗放在阴凉处以免太阳把它们晒枯。
3. Don’t believe him no matter what he may say. 无论他说什么，都不要相信他。
what和that的用法讲义--2023届高三英语复习备考
what和that的用法讲义what和that都是从句的引导词，或者说，都是可以连接主句和从句的连词。
要弄清楚这两个词的用法，我们首先要明确what和that分别都可以引导哪些从句。
一.关于whati what是名词性从句的引导词，名词性从句包括主语从句，宾语从句，表语从句，同位语从句。
所以，what可以引导的从句也就是上面提到的四类从句。
二.关于that(①that是名词性从句的引导词，所以，that也可以引导主语从句，宾语从句，表语从句，同位语从句。
②that是定语从句的引导词，所以，that还可以用来引导定语从句，放在所修饰的名词后面。
我们来看这样几个句子：1.This is what we are looking forward to. (表语从句)这是我们一直所期待的事情。
【分析】what引导的从句，放在了系动词is后面，放在表语的位置，是表语从句。
此时，what=the thing that所以，上面的句子可以改写成：This is the thing that we are looking forward to.2. What makes this shop different(主语从句)is that it offers more personal services. (表语从句)这家店与众不同的地方在于它提供更多的个人服务。
【分析】what引导的句子，放在句子开头，位于系动词is前面主语的位置，是主语从句。
此时，what=the thing that所以，上面的句子可以改写成：The thing that makes this shop different is that it offers more personal services .此外，原句that 引导的句子放在系动词is后面，放在表语的位置，所以是表语从句。
3. There are signs that restaurants are becoming more popular with families. (同位语从句)有迹象表明，餐馆在家庭中越来越受欢迎。
宾语从句中what和that
宾语从句中what和that
宾语从句中，what和that都可以用来引导从句，但两者在用法上存在一些区别。
what引导宾语从句时，在从句中可以作主语、宾语或表语，表示“所……的……”。
具体用法如下：
- 表示“……的东西或事情”，相当于“the thing that...;all that...;everything that...”。
- 表示“……的时间”，相当于“the time that”。
- 表示“……的人”，相当于“the person that”。
- 表示“……的地方”，相当于“the place that”。
- 表示“……的数目”，相当于“the amount/number that”。
that引导宾语从句时，在从句中不作句子成分，一般情况下可以省略。
但当有两个以上的宾语从句时，通常只能省掉第一个that。
在使用宾语从句时，需要注意句子结构和语法规则，选择合适的引导词来表达正确的意思。

名词性从句中that和what的用法
名词性从句中that和what的用法作者：晏飞来源：《求学·新高考版》2021年第07期在高考英语中，名词性从句中that和what的用法是学生容易混淆的一个问题。
高考英语语法填空题中，连接词的用法是必考的内容，其中连接词that和what的辨析是高考命题人喜欢利用的考点。
理解这个语法点，能够让小知识发挥大作用，使学生在高考英语备考中事半功倍。
如何才能理解that和what的用法？观察下面这几个句子，让我们从中归纳出一个普遍的规律。
1.What he wants is a book. 我想要的是一本书。
2.That he wants to go there is obvious. 很明显他想去那里。
3.The result is that we won the game.结果是我们赢得了比赛。
4.This is what we want to know.這就是我们想知道的内容。
5.Is what he told us true？他告诉我们的是真的吗？6.We should pay attention to what the teacher is saying.我们应该关注老师正在讲解的内容。
7.I have no doubt that he will come. 我不怀疑他回来。
8.I have no idea what he did that afternoon.我不知道他下午做了什么事。
9.We live in what is called China.我们住在一个被称为中国的地方。
10.What you see is what you get.你所看到的就是你所得到的。
分析以上十个句子，我们不难发现一个规律：从句中缺少句子成分用what，从句中句子结构完整用that。
That只是起到单纯的连接主句和从句的作用，然而what除了连接主句和从句外，还在从句中充当句子成分。
一些英语基础知识薄弱的同学看到这里可能仍然是一头雾水。

关系代词，因此，有学者称之为关系代词型what。如：
