请问this,that,one用法
就是这几年中考常考的优质解答
1)one, ones, that, those
That替换单数可数名词或不可数名词；one只替换单数的可数名词.
Eg:
The vase on the left is more beautiful than _the one_ on the right.
The coffee produced in Brazil is more famous than that in Mexico.
That只用于替换表示事物的名词, 而one/ones替换表示人和表示事物的名词皆可.
Eg:
His younger sister is taller than the elder one.
I need the plastic bags, not the paper ones.
That/ those一般不带前置定语,但必须有后置定语.One/ones都可.当替换词的后置定语用所有格的of短语或当替换词被所有格修饰时,不用one/ones而用that of/those of.
Eg:
I like the vase better than the one / that in another shop.
The windows of your flat are cleaner than those of mine.
A grandparent’s job is easier than that of a parent.
The computers in our school are connected to the Internet while those in their school aren’t.
That/ those用于替换有定冠词的名词；one/ones用于替换有不定冠词的名词.
Eg:
The style of the building is similar to that of a temple.
A CD player made in Japan costs more than one made in China.
2) it, this和 that
都可以替代前文已提到的事或情况,细微差别在于it不如其余两者那么强调.
Eg:
So she decided to paint the door pink. It upset the neighbours a bit.
So she decided to paint the house pink. That really upset the neighbours.
当前面提到的事物不止一件时, it通常指最先提到的事物,而this/that是指最后提到的事物.
Eg:
We keep the ice cream machine in the spare room. It is mainly used by the children. (指 the machine)
We keep the ice cream machine in the spare room. This/That is mainly used by the children. (指the spare room)
This可以出现在它所指代的事物之前；而that则指上文所提到的事物.
Eg:
Listen to this ! We will have three days off.
“A penny saved is a penny earned.” Who said that?
3) It和one
It用以指特定的前面提到过的事物,即：it和它替换的是同一个事物,it前无修饰语；而one用于替换与前提事物有共同之处但并不完全一样的事物,因此,one之前或之后一定有修饰语来加以区别.
Eg:
I bought a dictionary three years ago and I am still using___it___ now.
I bought a dictionary three years ago but I am going to buy a new __one_____soon.
It引起的几个易混淆的时间句型
It + be + 时间 + since-clause 这个句型表示从since 从句谓语动作发生以后到现在或过去所经过的一段时间,意为“自从.以来已多久了”
It is three years since his father passed away .
It + be + 时间 + before-clause
这个句型中的时间一般为表示一段时间的词语 (如：a long time , months , weeks , days ,hours , minutes ) ,主句中的谓语动词用肯定式,意为“过多长时间才.”.主句的谓语动词是否定式时,意为“没过多长时间就.”.主句的时态可用过去时was或将来时will be；用was 时,before从句的动词用一般过去时；用will be 时,before从句常用一般现在时.
她没过多久就背会了那些诗歌.
It was not long before she learned those poems by heart .
过了很久警察才来.
It was long before the police arrived .
要过好几个小时他才会作出决定.
It will be hours before he makes a decision .
要不了几个小时我们还会再见面的.

3. It + be + 时间 + when-clause
这个句型中, it 指时间,而且表示时间的词语前没有介词(时间一般为具体时间).主句中的谓语动词和从句中的谓语动词在时态上一般是一致的,主句是will be,when从句用一般现在时代替将来时.
It was already 8 o‘clock when we got home .
It was the next morning when we finished our work .
It will be midnight when they get there .
It + be + 时间 + that-clause 这个句型是个强调句型.例如：

(原句是：He made an important invention two years ago .
)It was at 5 o’clock that he practised playing the violin in the morning .
(原句是：He practised playing the violin at 5 o‘clock in the morning . )
比较：It was 5 o’clock when he started in the morning . (5 o‘clock前没有介词,这是个定语从句)
It + be + time + that-clause
这个句型属虚拟语气结构,不管主句中用的是 is 或 was ,that从句都须用动词的过去式或should + 动词原型(但不及用过去式普通),在time之前有时可加上high或about 以加强语气.例如：
It is time(that)we handed in our exercises .
(= It is time that we should hand in our exercises .)
It is high time (that ) she wrote a letter to her boyfriend .
It / This / That + the first(second , third …) time + that-clause
这个句型表示截止到说话时为止的某人的一种经历,关键是注意time前有序数词,主句是 is 时 ,从句要用现在完成时；如果主句用一般过去时was ,则从句须相应地用过去完成时.例如： This is the first time (that) these Europeans have visited the Great Wall . It was the fifth time (that) I had paid a friendly visit to Africa .
There起始的句型归纳：
1）there live/stand/lie/exist…
There lay a ditch two metres wide ahead.
2) There come/go/appear/occur/follow…用于描述某事的发生或某个动作的开始.
Eg: There will follow a break of 10 minutes and then we will go on with the lecture.
3) There being…（独立主格结构）
Eg: There being nothing left in the fridge, we had to do some shopping first.
4) …there to be结构常见于动词intend, mean, consider, hate, want等词后.
Eg: No one would expect there to be a war in his country.
I don’t want there to be another accident like this.
It 用于强调句
结构：It+动词be+强调部分+who(whom)/that+其他部分it可以用来对句子的某一成分加以强调.
Eg: Nancy saw your sister in Tokyo last week.
It was Nancy who saw your sister in Tokyo last week.
It was your sister whom Nancy saw in Tokyo last week.
It was in Tokyo that Nancy saw your sister last week.
It was last week that Nancy saw your sister in Tokyo.
有些否定句也可以改成这种强调结构：
It wasn’t until last summer that I heard from her.
I didn’t do all this for myself.
It wasn’t for myself that I did all this.
问句也可变成这种结构：
Who called him “comrade”?
Who was it that called him “comrade”?
How did you forget to lock the door?
How was it that you forgot to lock the door?

这个句型表示截止到说话时为止的某人的一种经历,关键是注意time前有序数词,主句是 is 时 ,从句要用现在完成时；如果主句用一般过去时was ,则从句须相应地用过去完成时.例如： This is the first time (that) these Europeans have visited the Great Wall . It was the fifth time (that) I had paid a friendly visit to Africa .
There起始的句型归纳：
1）there live/stand/lie/exist…
There lay a ditch two metres wide ahead.
2) There come/go/appear/occur/follow…用于描述某事的发生或某个动作的开始.
Eg: There will follow a break of 10 minutes and then we will go on with the lecture.
3) There being…（独立主格结构）
Eg: There being nothing left in the fridge, we had to do some shopping first.
4) …there to be结构常见于动词intend, mean, consider, hate, want等词后.
Eg: No one would expect there to be a war in his country.
I don’t want there to be another accident like this.
It 用于强调句
结构：It+动词be+强调部分+who(whom)/that+其他部分it可以用来对句子的某一成分加以强调.
Eg: Nancy saw your sister in Tokyo last week.
It was Nancy who saw your sister in Tokyo last week.
It was your sister whom Nancy saw in Tokyo last week.
It was in Tokyo that Nancy saw your sister last week.
It was last week that Nancy saw your sister in Tokyo.
有些否定句也可以改成这种强调结构：
It wasn’t until last summer that I heard from her.
I didn’t do all this for myself.
It wasn’t for myself that I did all this.
问句也可变成这种结构：
Who called him “comrade”?
Who was it that called him “comrade”?
How did you forget to lock the door?
How was it that you forgot to lock the door?

作为代词,it、that、this和one因其语意不像名词、动词、形容词那么明确,在阅读和翻译时,人们往往对其确切的指代关系搞 不清楚,造成对上下文意思的理解错误.从近几年的高考试题看,对上述代词测试的趋向十分明显,为此,了解这些代词的不同功能,弄清它们的指代关系,对阅读和高考都是有益的.
