它可以代替可数名词，也可以代替不可数名词。
代替可数名词时，复数形式为they/ them. 没有增加语义，所以不能带有任何定语。
二、one可以代替与前面同类不同一的事物；可以代替某类事物中的任何一个；可以做同位语，重复指代前面的事物，其后有定语从句用以进一步说明前面的名词。
one表泛指，相当于a/an+名词。

one可以根据语义在它的前面或后面加上一些定语。
one前面不能直接加不定冠词（a / an）或物主代词，one前已经有形容词时，则可以加不定冠词或物主代词；one前加the与否，取决于是否特指，如果特指就加the。
one既可以代指物，也可以代指人。
三、that代替与前面同类不同一的事物。
that表特指，相当于the+名词。
它可以代替可数名词，也可以代替不可数名词。
代替可数名词时，复数形式为those。
that可以根据语义在它的后面加上一些定语，多数是of短语；它的前面不能存在任何定语。
that只能代指物。
例句分析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”）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）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）The one ／That on the table is mine. （该句中The one代替事物，并且也可以用That）He is the teacher, the one who is loved by the students. （该句中the one代替人，不能用that）He advised the farmers to choose the best seed-heads, the ones ／those that had the best color. （该句中the ones代替事物，并且也可以用those）Cook was a strict but good captain, one who took good care of his sailors.The water in the well is cleaner than that in the river.。
one it that的区别是什么
one表示泛指，that和it表示特指。
that与所指名词为同类，但不是同一个，而it与所指名词为同一个。
one it that的区别一、one/ it/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。
例句：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myumbrella已经丢了)The umbrella you bought is cheaper than that I bought.(替代词that在该句中特指“theumbrella I bought”,以区别“the umbrella you bought”)二、one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。
例句：A chair made of steel is stronger than one made of wood.(该句中one可以换成achair)The water in the cup is hotter than that in the pot.(该句中that可以换成 thewater)三、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。
例句：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 thehouse.(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)四、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 one或the ones代替that或those。

6）the one(ones)或that ,those 指代某一名词做定语从句的先行词时，其关系代词which在that之后，which不能省略，而在the one、ones 之后,which可省略。
如：
①Their problem today is somewhat similar to that which they faced many years ago.
7）代替不可数名词时，应该用that。
