at least i have a few friends left whom i can count on. whom能换成that吗?他在句中做什么成分的?

如题所述

不可以.
在定语从句中,关系代词who (whom) 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:

用who (whom) 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 (whom)。如:

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 (whom)。如:

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 (whom)。如:

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 (whom)。如:

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。如:

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 (whom)。如:

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。如:

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。

这里属于第二种

不能,whom是定语从句的先行词,指代friends,在定语从句中做 count on 的宾语。表示人的宾语 先行词只能用whom本回答被提问者采纳
