代词one,it,that的用法区别
作者:俞江涛
代词one, itthat的用法在历届高考题中出现的频率较高,是高考的热点之一。笔者结合自己的教学实践在此谈谈它们的一些具体用法,希望能对同学们有一定的帮助。
1.one, it,that常常用来代替或避免重复某个名词。例如:
②-Where did you find yourwatch?
③The population of China is larger than that of any othercountry.
2.one可指人或物,只替代单数可数名词,复数用ones.One是泛指,但有限定修饰语,如the, this,that…修饰就变成了特指。如:
①One must do one's duty.
③The new designs are much better than the old ones.
3.that只指物,不指人,可替代可数名词或不可数名词,具有“特指”性质。指的是同类事物中的另一样东西,即同类异物。如:Thelibrary of our school is bigger than that ofyours.(that代替的是另一个图书馆。)
4.One 和that
①I will take the seat next to the one(=that)by thewindow.我就坐窗口的那个座位旁边。
②I prefer the large box to the small one.(one不可用that替换 )。
①Today's cellphones are smaller than those(=the ones)used inthe past.
②The students who do best in exam are not always those(=theones) with the best brains.
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theone、ones 之后,which可省略。如:
①Their problem today is somewhat similar to that which theyfaced many years ago.
7.代替不可数名词时,应该用that。如:The equipmentis different from that.
8..it代替上文所提到的名词时,是指同类事物中的同一样东西,即同类事物。如:
I have lost my pen. I'm looking for it.
9.it和that可代替前面整个句子的意思,而one却不能;that可引导一个限定性定语从句,代替某个先行词(单复数名词均可),it和one则不能;it可代替不定式、动名词或从句,用作形式主语或形式宾语,也可用于强调句型中,而one和that则不能。如:
①-I will make bed for you. –It is very kind of you.
②Jim said he had read my novel.But that was not possible.
③A clock is an instrument that tells time.
④The students that surf the Internet will be punished by theteacher.
