one,that,it,the one用法解析
  发布者:学科专家   来源:星沙英语  发布时间:2012-01-16

1. itone that三者均可用作代词, 指代前面提到的名词。一般说来, it指代同名同物; onethat则指代同名异物。
I have lost my umbrella; I'm looking for it.
(该句中it就是指前面的my umbrella
I have lost my umbrella; I think I must buy one.
one在该句中表泛指, 因为my umbrella已经丢了)
The umbrella you bought is cheaper than that I bought.
(替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”
2. one
that虽可用来指代同名异物, one为泛指, 相当于aan+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 aan some any; that所指代的名词的修饰语往往是the this that
A chair made of steel is stronger than one made of wood.
(该句中one可以换成a chair
The water in the cup is hotter than that in the pot.
(该句中that可以换成 the water
3. one
只能代替可数名词单数, 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, 代替可数名词复数时用 those

one代替可数名词单数pen

4. one
既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the onethe ones代替thatthose

(该句中the one代替人, 不能用that

those that had the best color. (该句中the ones代替事物, 并且也可以用those
5. one
一般有前置修饰语, 有时也可有后置修饰语或不用修饰语。而 that不能有前置修饰语, 但可有后置修饰语。
