题目内容
9.Our clothes are cheap,buttheirs(they) are dear.分析 我们的衣服很便宜,但是他们的贵.
解答 答案:theirs.上文Our clothes are cheap是说我们的衣服很便宜,but转折,结合所给的人称代词they,故后面一句的句意是说他们的衣服贵,句中缺少主语,主语是他们的衣服their clothes,clothes上文已经出现,为了避免重复,故用名词性物主代词theirs代替their clothes,作主语,故答案是theirs.
点评 名词性物主代词=形容词性物主代词+名词为避免重复使用名词,有时可用"名词性物主代词"来代替"形容词性物主代词+名词"的形式.
