one和it在指代上的区别（oneitthat的用法区别）

初中英语，今天为大家分享代词one，it，that的用法区别。

代词one，it，that的用法区别

1.I like the blue sweater. I'll take it.我喜欢那件蓝色的毛衣。我要了。

2.-I like blue sweaters.（顾客）我喜欢蓝色的毛衣。

-How about this one?（服务员）这个怎么样？

3.The like which I want to buy is more beautiful than that he has.我想买的那种比他买的还要漂亮。

看以上三个句子，注意思考句中it ,one ,that 的含义：it 应该指the blue sweater，one指any blue sweater（任何一件蓝毛衣），that指 his like 。

下面我们来共同学习一下它们的不同吧！

1.它们均可作代词，用来指代上文提到的名词，但it 用来代替不可数名词或单数可数名词，且是“同名同物”；one 用来代替单数可数名词，表泛指，是“同名异物”；that 用来代替特指的不可数名词和单数可数名词。

习题练习：

⑴.-Do you see my dictionary,Dad? I can't find__.

-No, I don't.

A. it B.one C.that D.the one

⑵.We have various summer camps for your holidays.

You can choose__based on your own interists.

A.either B.each C.one D.it

⑶.The population of Henan Province is larger than__of any province in China.

A.one B.it C.that D.the one

答案：⑴. A ⑵. C ⑶.C

2.it还可以替名词性从句，动词-ing短语或动名词以及不定式短语；同时it也可以作形式主语或形式宾语，而one 和that 无此用法。

eg: If you take a bus at the airport; it will take you half an hour to get there.如果你在机场坐公共汽车，你要花半个小时才能到那儿。

"it"作形式主语，代替to get there

I found it hard to understand.我很难理解。

"it"代替to understand

3.one 和that 又有什么区别呢？

⑴one为泛指，相当于a/an 名词，that为特指，相当于the 名词，所以one所指代的名词的修饰语一般为a/an/some/any；that所指代的名词的修饰语往往是the/this/that.

eg:The water in the cup is hotter than that in the pot.杯子里的水比锅里的热。

A chair made of steel is stronger than one made of wood.钢做的椅子比木头做的椅子结实。

⑵one只能代替单数可数名词，代替可数名词复数时用ones,that 既可以代替不可数名词，也可以代替可数名词单数，代替可数复数时用those.eg:I like this pen more than that one .（one代替可数名词单数pen）我比较喜欢这支笔

There were a few young people and some older ones in the people.(ones代替可数名词复数people)有几个年轻人和一些老年人在。

Mary's handwriting is much better than that if peter.(that 代替不可数名词handwriting)玛丽的笔迹比彼得的好多了。

These pictures are more beautiful than those .(those代替可数名词复数pictures)这些照片比那些漂亮多了⑶one既可代替食物，也可代替人，that只能代替事物。有时用the one 和the ones 代替that和those.

eg:The one /that on the table is mine.桌子上的那个是我的。

He is the teacher,the one who is loved by the students.(该句中the one 代替人，不能用that)他是老师，受学生爱戴的老师。

以上就是为大家分享的知识点，现在在这里再进行总结一下：it ,one ,that都可代上文名词，it可代可数单和不可数名词，且是同一个物，one 可代可数名词单数，且是同类不同物。that也可代可数单和不可数名词，往往是特指的。one复数为ones，that复数为those，it作用大大的，还可代替动词不定式，动名词，也可作形式主语，形式宾语。
