one作代詞的用法如下，
1.one替代由可數(shù)名詞所表示的一類人或事物中的任何一個(gè),即泛指中的強(qiáng)調(diào).這時(shí),替代詞one前面不可加任何限定詞.例如:
1)I hope there are enough glasses for each guest to have one.
2)A color TV set made in Japan costs more than one made in China.
3)-Who can lend me a Chinese-English dictionary?
-I have one.
2.one用來(lái)替代特指的同一類人或事物的可數(shù)名詞時(shí),其前面必須加上限定詞(如a,the, this, that等)、物主代詞或形容詞加以修飾.例如:
1)If you don't like this blue coat, you can buy a black one.
2)I don't want the book on the shelf, I want this one on the desk.
3)Your old bike is white, while my old one is black.
3.one在定語(yǔ)從句中作先行詞替代特指的同一類人或事物時(shí),其前面必須用定冠詞the限定,但不可用that替換.如果先行詞為'one of...',其關(guān)系代詞在定語(yǔ)從句中作主語(yǔ),從句中的謂語(yǔ)動(dòng)詞常用復(fù)數(shù)形式.例如:
1)This farm is the one that we visited last summer.(句中the one代替this farm,作先行詞,不可用that替代)
2)This is one of the highest buildings that have been built in our city recently.
3)Zhang Lei is the very one of the students who has been praised at the meeting.
4.one的復(fù)數(shù)形式為ones,作替代詞時(shí),只可替代同一類人或事物的復(fù)數(shù)名詞,其前面必須有限定詞,如the, some, all等修飾.但不能用數(shù)詞或many修飾.例如:
1)Mr. Zhang gave the textbooks to the pupils except the ones who had already taken them.(句中the ones可用those替代)
2)I don't want to buy these small pears; I want some large ones.
3)She wants to buy some new clothes and throw away all her old ones.
5.one在句中不可替代不可數(shù)名詞.在句中如果出現(xiàn)了同一個(gè)不可數(shù)名詞時(shí),則需要重復(fù)前一個(gè)名詞,或者省略那個(gè)名詞.例如:
1)I prefer black coffee to white (coffee) .(white coffee中的coffee可省略也可不省,但不可用one替代coffee)
2)Folk music is the music that I like most.(不可用the one替代the music)

2)-Have you still kept your old furniture?

2)I think it is no good parents doing anything for their children.(it替代動(dòng)名詞的復(fù)合結(jié)構(gòu)parents doing anything for短語(yǔ))
