定语从句who作表语
当主句是以who开头的特殊疑问句时,引导词只能用that。以下内容是小编为您精心整理的定语从句who作表语,欢迎参考!
定语从句who作表语一
所谓表语从句就是用一个句子作为表语。它跟在be动词或系动词后面,说明主语是什么或者怎么样的。例如:
a)He has become what he wanted to be.他已经成为了想成为的那个人。
b)The problem is when we have a meeting. 问题是我们什么时候能举行会谈。
我们说过,宾语从句要用陈述语序。其实,表语从句也是如此。上面的例子如果写The problem is when do we have a meeting就错了。
但是和宾语从句不同的是,宾语从句中的'that可以省略,但在表语从句中,这个懒千万不能偷!
His suggestion is that we can try to catch the next train. 他建议我们去赶下一班火车。
上面的例句中,引导表语从句的that一定不能省略哦。
另外,通常情况下,if和whether可以互换,但是在表语从句中却行不通,一定要用whether。例如:
The question is whether you have enough time to do it.问题在于你是否有足够的时间去做。
千万不能写成the question is if you have enough time to do it哦!
定语从句who作表语二
在定语从句中,关系代词who 和that都可指人和物,在一般情况下,可以互换使用,但在下列情况下值得注意,之间的区别:
一、用who 而不用that的情形
1.在非限制性定语从句中的先行词指人时,只能用who 。
例:My sister, who is studying abroad, sent me a beautiful present just before this
Christmas.
我姐姐,她在国外学习,就在圣诞节前给我寄来了漂亮的礼物。
2.当定语从句对指人的先行词进行隔位修饰时,只能用who。
例:Do you know the girl in front of the blackboard who is speaking to the
students?
你认识黑板前面正在给学生们讲话的那位女孩子吗?
3.当先行词为people和those时,只能用who.
例:Those who want to go there come here please.
那些想去那儿的人请来这边。
4.当先行词为one, ones, anyone, everyone, none, all(指人) 时,只能用who。
例:Anyone who is against us is our enemy.
任何反对我们的人就是我们的敌人。
5. 先行词指人,而关系代词在从句中作主语时,一般多用who。
例:The man who came here yesterday said he would come again in a few days.
昨天来这儿的那个人说过几天他会再来。
6. 在there be句型中名词的定语从句多用who 。
例:There are students in our class who / whom you have met.
我们班有些学生你见过。
7.当句子中有两个指人的现行词分别带有两个定语从句时,若一个定语从句的引导词为that, 那么,另一个定语从句的引导词必定为who。
例:The boy that you met just now is Li Ming’s brother who just graduated from a
university.
刚才你会到的那个男孩是李明的刚从大学毕业的弟弟。
二、用that 而不用who的情形
1.当先行词前面有形容词的最高级或序数词修饰时,引导词只能用that。
例:The tallest player that plays football for our team is from Shandong.
在为我们队踢足球的最高哪个运动员来自山东。
2.当先行词前面有only, some, any, no, every, little, few, much, all,
very形容词修饰时,引导词只能用that。
例:He is the only student that said “no” to the teacher.
他是唯一的一个对老师说“不”的学生
3.当主句是以who开头的特殊疑问句时,引导词只能用that。
例:Who is woman that you talked with just now?
刚才跟你谈话的那位妇女是谁?
4.当先行词是一个既指人又指物的并列词组时。
例:I made a speech on the men and things that I had seen abroad.
我就我在国外所见到的人和事作了报告。
5.当关系代词在定语从句中作表语时(可省略).
