1、one, that, it, the one用法解析1. itone that三者均可用作代詞, 指代前面提到的名詞。一般說來, it指代同名同物; one與that則指代同名異物。I have lost my umbrella; I'm looking for it. （該句中it就是指前面的my umbrella）I have lost my umbrella; I think I must buy one. （one在該句中表泛指, 因?yàn)閙y umbrella已經(jīng)丟了）The umbrella you bought is cheaper than that I boug

2、ht. （that在該句中特指“the umbrella I bought”, 以區(qū)別“the umbrella you bought”）2.  one與that雖可用來指代同名異物, 但one為泛指, 相當(dāng)于aan名詞; that為特指, 相當(dāng)于the 名詞。所以one所指代的名詞的修飾語(yǔ)一般為 aan some any; that所指代的名詞的修飾語(yǔ)往往是the this that。A chair made of steel is stronger than one made of wood. （該句中one可以換成a chair）The water in the cup is

3、hotter than that in the pot. （該句中that可以換成 the water）3.  one只能代替可數(shù)名詞單數(shù), 代替可數(shù)名詞復(fù)數(shù)時(shí)用ones; that既可以代替不可數(shù)名詞也可以代替可數(shù)名詞單數(shù), 代替可數(shù)名詞復(fù)數(shù)時(shí)用 those。I like this pen more than that one. （one代替可數(shù)名詞單數(shù)pen）There were a few young people and some older ones in the house. （ones代替可數(shù)名詞復(fù)數(shù)people）Mary's handwriting is fa

4、r better than that of Peter. （that代替不可數(shù)名詞 handwriting）These pictures are more beautiful than those. （those代替可數(shù)名詞復(fù)數(shù) pictures）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。有時(shí)可以用the one或the ones代替that或those。The one That on the table is mine. （該句中The one代替事物, 并且也可以用That）He is the teacher, the one who is l

5、oved by the students. （該句中the one代替人, 不能用that）He advised the farmers to choose the best seeds, the ones those that had the best color. （該句中the ones代替事物, 并且也可以用those）5.   it可以替代句中的不定式或從句等, 充當(dāng)形式主語(yǔ)或形式賓語(yǔ)。one與that均無此用法。 It is known to everybody that the moon travels around the earth once every
