that与所指名词为同类，但不是同一个
it 与所指名词为同一个。

The hat you bought is bigger than that I bought.(同类但不同个)

Meeting my uncle after all these years was an unforgettable moment，_____ I will always treasure．（NMET2002）
A．that B．one C．it D．what
此题的正确答案为B，这里one作代词，指代a moment，在句中作an unforgettable moment 的同位语。
(一)下面就one在中学英语中的常见用法作简要归纳：
一、one作人称代词可以笼统地指任何人、某一伙人中的一个人或说话人。当one笼统地指任何人时，其用法相当于you指代任何人。在书面语中，one比you更常见。
1．One can\'t succeed without working hard．一个人不努力工作是不会成功的。
2．He is the one who never troubles about personal interests．他是一个从不计较个人利益的人。
二、one作为人称代词，其所有格为one\'s，反身代词为oneself。如果one用于句首，后面再用代词one，oneself或one\'s，可以用he，him，himself或his代替。在反意疑问句中，若主语是one，疑问部分代词可用one或he。
1．One should give oneself／himself plenty of time to rest．一个人应该给自己留出充足的休息时间。
2．One has his own right to speak out his mind at the meeting，doesn\'t one ／he？在会议上人们有权说出自己的想法，对吗？
三、one作代词，代替前面提到的人或物，以避免重复。此时one只能代替可数名词，其复数形式为ones。one或ones用于this，that，these，those，either，neither或形容词最高级后面时，常常可以省略。
1．The new designs are much better than the old ones．这些新设计比那些旧的好得多。
2．I think my dog is the fastest（one）．我想我的狗是跑得最快的一条。
四、有时one ／ones的前面可以用冠词。用不定冠词a ／an时，one的前面必须有形容词修饰。当数词加ones时，ones常省略，当ones有形容词修饰时，则不能省略。另外，名词所有格后面，也常省略one ／ones，若one ／ones有形容词修饰，则不能省略。
1．Your car isn\'t fast enough．Let\'s take Tom\'s．你的车不够快，咱们乘汤姆的吧。
2．My computer doesn\'t work well．May I use your new one？我的计算机工作不正常。我可以用你的新的吗？
五、中学英语中还有一些由one构成的常用短语和固定结构。下面仅列举几个常用的重点短语和固定结构：one by one（一个一个地），one or two（一两个；很少的），one after the other ／one after another（一个接一个），for one thing．．．for another（首先……再者；一方面……另一方面）。
1．There are still one or two problems to be settled．仍然有一两个问题需要解决。
2．I can\'t travel this summer．For one thing，I\'m short of money；for another，I have not much spare time．今年夏天我不能旅游了。首先，我缺钱；再者，我也没有太多的空余时间。1）不用that的情况
a) 在引导非限定性定语从句时。
(错)The tree, that is four hundred years old, is very famous here.
b) 介词后不能用。
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.
2) 只能用that作为定语从句的关系代词的情况
a)在there be 句型中，只用that，不用which。
b)在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
c)先行词有the only, the very修饰时，只用that。
d)先行词为序数词、数词、形容词最高级时，只用that。.
e)先行词既有人，又有物时。
举例：
All that is needed is a supply of oil.
所需的只是供油问题。
Finally, the thief handed everything that he had stolen to the police.
那贼最终把偷的全部东西交给了警察。
it是个非常简单的单词,但其用法却很灵活。it可以作代词,也可以作引导词。现结合部分高考试题说说它的一些用法:

It is impossible (for so few workers) to do so much work in a single day.
It was foolish of her to waste money on such clothes.
2)It+be+adj. / n.+clause.例如:
It is certain that Tom will do well in the exam.
3)It+be+adj. / 意义相当于形容词的名词词组+动名词. 例如:
It\'s no use trying to repair the ship. These holes are much too big.
4)It+take+(sb.) some time / some money+to do sth. 例如:
It will take them more than ten years to complete the Three Gorges Dam.
5)It+be+said / reported / told等+that-clause. 例如:
It is said that he will leave for Beijing tomorrow.
6)It+vt.+sb.+that-clause. 例如:

常用it作形式宾语的句式有:
1)S.+vt.+it+adj. / n.+(for sb.) to do sth. 例如:
Do you think it possible for them to send an engineer there?
2)S.+vt.+it+adj. / n.+doing sth. 例如:

2011届高考英语一轮复习讲解：it的用法
2011届高考英语一轮复习讲解：it的用法【知识要点】 It的用法 （一）作人称代词 1、it代替前面（或后面）的单数名词或分句等所表示的事物。 e.g. You cannot eat your cake but have it.（it代替前面的cake） Although we cannot see it, there is air all around us. （it代替后面的air） They say he has left town, but I don’t believe it.（it代替前面They…town分句中的情况） 2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree） The baby cried because it was hungry. （it代替前面的baby） 3、在某些习惯说法中，可以代替人。 e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me. ---- Who are singing? ---- It is the children. ---- The light is still on in the lab. It must be the third-year students doing the experiment. 4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China） The climate of South China is much better than that of Japan.（that指the climate）（二）作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the f actory. It is eighteen square metres in area. What does it matter? （三）作强调词，构成强调结构

选修6It的用法语法练习题及答案
It的用法 It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。 1．(NMET98) It was only when I reread his poems recently ___ I began to appreciate their beauty．A．until B．that C．then D．so 正确答案：B 此题考查强调句，所以用that。 2．(NMET98) I hate____when people talk with their mouths full． A．it B．that C．these D．them 正确答案：A 此题考查it作形式宾语的用法，所以选A。 3．(MET91，短文改错)David and I did not agree and David pointed to a path which he thought it would probably lead to a village． 正确答案：去掉it，因为定语从句中已有宾语which。 一、要点点拔 1．代替上文中提到过的人或事物。指代人时，一般用于小孩或身份不十分明朗的人。 1) －Who is the baby? －It‘s my teacher’s son． 2) －Who is that gentleman? －It's my friend Tom．He(不可用It) wants to see you． 2．用于表达天气、环境、时间、距离、季节等。例如： 1) It’s half an hour’s walk from here to our school． 2) It‘s nice and warm here． 3) But it's two o'clock now, and it's time for us to go to school． 3．用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。 1).It 替代真正的主语——动词不定式短语. It is easier to say than to do . It is a good act to help the others. 2).it 替代真正的主语——动名词短语,以动名词短语做主语的句子，主要在以no good, no use, no harm, dangerous, foolish 等词作表语的句中. It’s no harm drinking running water in that area。 It’s foolish talking like that. 3).it 替代从句作主语，用从句做主语的带it 的句子很多,常见的有下面几类： ①It is a pity (a shame ,a fact ,a wonder ,a good thing,etc. )that… It is a shame that he didn’t pass the exam. ②It is strange ( surprising,obvious ,true, good,possible,clear,etc. ) that…。 It was clear that they had no desire for peace. ③It seems (happened ,turned out,etc.)that… It seemed that things were not as they expected. ④It is said ( decided ,expected ,etc)that … It is said that the tickets have been sold out . 4.用作形式宾语。
