这个定语从句为什么要用“which”?
New zeland has a population of about 3.8 million people,of which about fourteen percent are Maori.
因为此句是非限定性定语从句,
that与which的用法区别中有提到:1.引导非限制性定语从句时,通常要用which
例句:
The current,which is very rapid,makes the river dangerous.水流湍急,使这条河很危险.
He has to work on Sundays,which he doesn’t like.他得在星期天工作,他是不喜欢这样的.
The London team,which played so well last season,has done badly this season.伦敦队上一个季度打得很好,这个季度却打得很差.
2.直接放在介词后作宾语时,通常要用which:
She may be late,in which case we ought to wait for her.她可能晚到,那样我们就要等等她.
The documents for which they were searching have been recovered.他们找寻的文件已找到了.
This morning some port wine came,for which I have to thank you.今天早上送来一些波尔图葡萄酒,为此我得向你道谢.
注:有时“介词+which”引导的定语从句可以转换成“介词+which+不定式”结构:
He had only the long nights in which he could study.=He had only the long nights in which to study.他只有漫漫长夜可用来学习.
而此句中,有逗号隔开,是非限定性定语从句的标志,且关系词which前有介词of,故用which.
希望那个你能明白!
