which和it区别(it和which的区别用法)

it和which的区别用法

that,what和which

1. that引导名词性从句时只起连接从句的作用,本身没有任何意义,因此在从句中不充当任何句子成分,它的使用须注意以下几点: A. 引导宾语从句时,that常可省略,但如果主句后跟有并列宾语从句时,只能省略第一个that;若宾语从句前插有别的从句时,that也不能省略。例如: He told me (that) he was all right and that he would come to see me when he was free. 他告诉我说他很好,并说在他有空时来看我。 B. that引导主语从句位于句首时不可省略.如果it作形式主语,而that从句置于句末, 这时that可以省略。例如: That he has lost his work is not true. 他丢了工作不是真的。 =It is not true (that) he has lost his work. C.当主语为the reason时,注意应用that 引导其表语从句,不能受汉语影响而误用because。例如: The reason why he was late was that he missed the early bus. 他迟到的原因是他没赶上早班车.(此句中的that不可用because代替) D.引导同位语从句时,切不可错用which。例如: Word has come that some American guests will come to visit our school next week. 有消息说下周将有一些美国客人来我校参观。

2. what与which引导名词性从句时都在从句中充当句子的某一成份,如主语、表语、宾语或定语,其区别是:what表示泛指的事物,常译为"什么"或"所……的事物", whatever是它的强语势"无论什么";which表示特定事物中的"哪一个(些)",一般情况下在从句中充当定语,后接名词,在一定的语境中,它所修饰的名词可以省略,whichever是它的强语势"无论哪一个(些)"。例如: I believe what (whatever) he says. 我相信他说的(不管他说什么我都相信)。 I will give her which (whichever) book she likes on the shelf. 这个书架上的(任何一本)书,只要她喜欢,我都会给她。

which和it的用法区别

这是个介词+关系代词引导的定语从句，which 作介词from 的宾语，指代friendship 。

It was a friendship from which a romance was nurtured.

翻译：这是一种友谊，它孕育了一段浪漫。

把后面的从句补充完整，就是：

a romance was nurtured from the friendship、

翻译：这份友谊孕育了一段浪漫故事。

which和which is的区别

which与that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。如：She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请，这是她意想不到的。

2. 直接放在介词后作宾语时，通常要用which。如：The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。

3. much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that。如：There was little that the enemy could do but surrender. 敌人无法,只有投降了。All [Everything] that can be done must be done. 凡能that can be done must be done.

4. 当先行词有the very, the only, the same 等修饰时，通常用that。如：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。如：。如：This is the best dictionary that I’ve ever used. 这是我用过的最好的词典。The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。

6. 当关系代词在定语从句中用作表语时，通常用that。如：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。如：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。他们谈论了使他们印象最深的人和事。

8. 当要避免重复时。如：Which is the course that we are to take? 我们选哪门课程？

it 和which

It, 指代的是 war. 其他选项则不是, which, what 不能做从句主语, 可以做宾语. that 则是太含糊, 读者不能确定指代的是哪个词.

which it is和which is

这是正确的例句On average, the economists also don't expect oil prices to spiral out of control, with the average forecast putting the price of a barrel of crude at about$ 72 by december of 2010--which is right around its current level.总体来看，经济学家们认为，油价的上涨不会失控，平均的预测是到2010年12月前原油价格为每桶约72美元，这和目前的水平接近。It is hard to tell which is right.很难判断哪个是对的。

语法填空which与it的区别

it和which的区别为：指代不同、语法不同、侧重点不同。

一、指代不同

1、it：这个。

2、which：这些。

二、语法不同

1、it：it可以作先行词，用于强调句型中,强调主语、宾语、时间状语、地点状语、介词宾语或从句等,强调句型中的it一般指已发生过的事,而不指尚未发生或提及的事。

2、which：which用作关系代词,可引导限制性定语从句或非限制性定语从句,引导非限制性定语从句时which可以用整个主句作为其前行词,相当于and that,有时还可引导不定式短语从句。

三、侧重点不同

1、it：it不是定语从句引导词。

2、which：which引导的是非限制性定语从句
