英语的代替现象比汉语普遍,使用代词的场合比汉语多。大多数句子中均用代词代替上文谈到的人、事物或情况,避免了对较多名词、冠词的反复使用,这样大大简化了句子。最常用于表示替代关系的词语有it,that,which,one,so等,近几年高考试题中均对这些词的用法进行了考查,可见这几个替代词的用法非常重要。下面归纳它们表示替代时的不同用法。一、it的用法1、it指代上文所提事物的本身(it表时间、强调等的用法此处不阐明),如果所代替的事物为复数,则应该用they或them表示。2、it也可以用来代替上文所提到的一件事。1.the parkers bought a new house but _____ will need a lot of work before they can move in. nmet2001,25 a.they b.it c.one d.which 2.i am looking for a house. i’d like ____ with a brook around_____. a.one,it b.it,it c.one,one d.it,one3.mary’s mother always told her to work hard, but______didn’t help. a.one b.he c.she d.it4. —do you like these photos? — yes, ____are very beautiful and i like____ very much.a.they,those b.they,them c.ones,ones d.the ones, the o
