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)
it that one的用法区别如下:
①it/one/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;one与that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”)
②one与that虽可用来指代同名异物,但one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。
A chair made of steel is stronger than one made ofwood.(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)
③one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。
I like this pen more than that one.(one代替可数名词单数pen)
There were a few young people and some older ones in the house.(ones代替可数名词复数people)
Mary's handwriting is far better than that of Peter.(that代替不可数名词 handwriting)
These pictures are more beautiful than those.(those代替可数名词复数 pictures)
