which与what的区别(最新整理)

1、名词性从句与定语从句的区别名词性从句在句子中做了一个成分，可以是主语、宾语如果缺少了它，句子就不完整了。如：what he wants to tell us is not clear. what he wants to tell us 就是名词性从句，在句子中做主语成分。 如果少了它，句子就变成 is not clear.就不是一个完整句子。定语从句起修饰作用的，修饰句子中的某个成分。去掉它，句子仍然完整。 如 ：those people who are bored to death are pathetic. who are bored to death 就是定语从句，修饰 those pe

2、ople 没了它，句子变为 those people are pathetic.有主语、be 动词、状语，是完整的结构。名词性从句（非定语从句！）中 which 与 what 的区别what 可以是感吧词,形容词,副词,名词,代词; which 只能是形容词和代词what subject do you like?你喜欢什么事物?什么样的,为形容词;which subject do you like?你喜欢哪一种的事物?哪个(种)的,也为形容词.只有相同词性才可以替换.1,what 表示什么，what class are you in 指你在什么班，比如艺术班，书法班， 数学班，等等，但 whi

3、ch class are you in 指的是你在哪一个班，问话的人事先知道有哪些班，然后问对方在那个，或一班，二班，或艺术、数学其中的班。 二者在这个用法上的区别不是特别大。有时候可以换用，根据习惯用。 2，当这个句子用在非限制性从句中时，就必须用 which，而不是 what.比如， the class 4, which class are you in, is a goog class.【1】做疑问词，what 是指“什么”例如：whats your name?，which 是指“哪一个物体”which pen do you want.。【2】which 一般可做定语从句连接词，例如：t

4、his is the pen which i want. what 一般可做名词性从句的引导词。例如：what you said is true.定语从句和名词性从句的区别第一，定语从句有先行词，且先行词可以放入后面的从句中使从句完整；名词性从句中的主语从句、表语从句和宾语从句没有先行词，同位语从句有先行词但在从句中不做成分。e.g. the news that they told me excited me.（the news 可以放入从句中，使句子完整，即 they told me the news）the news that our team won excited me.(the ne

5、ws 无法放入从句中，所以是同位语从句）第二，在句子中起名词作用的句子叫名词从句 (noun clauses）。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，定语从句分为限定性和非限定性从句两种。第三，最关键也是最重要的区别：1. 名词性从句和定语从句的最本质的不同点在于，前者在句子中做名词，而后者相当于形容词，修饰或限制名词或代词。名词性从句由 that 引导时，通常不充当从句的句子成分，故 that 可省去。但定语从句由 that 引导

6、时，如在从句中充当主语时，则 that 不能省去。2. 使用中最大的区别：定语从句由于在句子中只作定语，故去掉它，整个句子还完整，就像普通的句子去掉一个定语不影响原句的完整性一样。但名词性从句由于它们充当的是句子的骨干成分（主语，宾语或表语），故去掉它们，原句就不通了。如上面的 a 句，去掉了主语从句 that he has become a rich man，原句变成 is known to all in our town。就失去了完整性。而 b 句，去掉定语从句部分 that is on the desk 后，原句变成 the pen is mine 还是通的。the reasonhe g

7、ave for not coming washis mother wouldnt allow him to.a. for which; that b. which; becausec. why; that d. which; that 选 d 为什么啊 请问达了为什么不用 whywhy 是引导定语从句的关系副词，which 是关系代词，定语从句后面该用关系副词还是关系代词，这样来判断，当先行词是 reason，我们有三个后选项： why,which/that. 再判断关系词在从句中的成分，当关系词在从句中充当主语或宾语时，用 which/that，当先行词在从句中充当状语时用 why 引导。此

8、句中从句 he gave 后缺少宾语, 所以用 which 充当 gave 的宾语。第二个空在 be 动词之后是表语从句，表语从句可有 what 和 that 引导，what 引导时，它在句子中充当成分，而 that 引导时不充当成分，仅作引导词，此句表语从句中主谓宾都在不缺少成分，所以用 that.this is the reasonhe gave us for carrying out the plan.a. whyb. becausec. whichd. what答案是 c 我选了 athis is the reasonhe didnt come to the meeting. a,in

9、 whichb,with whichc,thatd,for whichthe reason why 要接定语从句，而 the reason for 后接一个名词性的结构，二者不能完全一致。但当 for 后是一个完整的句子时，可用 for which。1. the reason( for the change) is lack of money, pure and simple.进行更改的原因就是缺少经费.1. the reason for the change is lack of money, pure and simple.进行更改的原因就是缺少经费.2. that is one reas

10、on for my having entered you at riverview.这是我让你上河景中学的原因之一。3. the reason (for his success) is not far to seek he worked hard.他成功的原因不难找，那就是他勤奋工作。the reason for +短语the reason why + 从句“”“”at the end, xiao bian gives you a passage. minand once said, people who learn to learn are very happy people. in eve
