一个很难解释的高考英语单选题---语法高手进---不会不要作答，谢谢

Question

I have many friends, ___ some are businessmen.
A. of them B. from which C. who of D. of whom
some of them我当然熟悉。关键现在时of whom some ，语序有问题。
我见过most of whom 这样非限定性定语从句。
我觉得这题应该是some of whom 。语序总觉得怪怪的

Answer 1

一个很难解释的高考英语单选题---语法高手进---不会不要作答，
I have many friends, ___ some are businessmen.
A. of them B. from which C. who of D. of whom
答：D
译：我有很多朋友，其中有些是商人。
析：这是高考题。考查非限制性定语从句中介词+关系代词的用法。先行词是friends,是人，不用which,可排除B。 them是人称代词，不能引导定语从句，排除A。如用A，则用并列连词and，且说：and some of them are businessmen, 不必这么“倒装”。
从句还原就是：some of whom(=them=my friends) are business, 由于介词+关系代词whom起到引导的作用，所以只好将some这个从句的主语放到它后面了。追问

126、It is reported that two school, (both of which) are being built in my hometown, will open next year.
45、We shouldn't spend our money testing so many people, (most of whom) are healthy.
看这两个句子，并没有把of which置于both之前，也没有把of whom 置于most之前。

但是我们这个题，就是of whom 置于some之前了。这是什么原因？

追答

答：其实在非限制性定语从句中，这两种方式都是可以的。没有什么特别的原因，跟说话者本身的习惯有关。这句话，说：。。。 some of whom are ....也是可以的。
不过限制性定语从句中，最后是介词+关系代词放前面。如：
The book of which the cover is blue is mine.
=The book whose cover is blue is mine.
比较：The book the cover of which is blue is mine.
这句中the book后紧跟另一个名词，会造成暂时断句的困难，而非限制性定语从句，这个逗号在中间起到了分隔的作用，就没有这个问题。这是我的体会。

Answer 2

some of whom are businessmen.这样可以理解吧。
在定语从句的考点：代词/名词/数词+of +which(先行词指物)/ whom(先行词指人)，这个结构里，常会把前面的代词/名词/数词放在关系词的后面，就如你这题。其他的如：
I invited ten friends to have dinner , three of whom let me down.也能讲成：of whom three let me down.
选择D。追问

你的意思是本题本来就是some of whom，只不过经常会把of whom 提前，这两种方式都是对的。是这个意思吗？
比如:We shouldn't spend our money testing so many people, (most of whom) are healthy.
= We shouldn't spend our money testing so many people, (of whom most) are healthy.
对吗？
