问题描述

下面哪句对? 或是两句都对?

He has a lot of books, many of which are about African Americans.

He has a lot of books, of which many are about African Americans.

老师答疑

唐老师：

两句都对。类似的用法如：

1. 共有500名乘客，其中有121名溺弊。

There were 500 passengers, 121 of whom drowned. 

There were 500 passengers, of whom 121 drowned. 

2. 我看见了3张折叠床，其中两张已有人占了。

I saw three camp beds, two of which were occupied. 

I saw three camp beds, of which two were occupied. 

黎老师：

《牛津英语用法指南》第三版498.8节指出：

在非限制性从句中，数量限定词（如some, any, none, all,both, several, enough, many 和 few）可以和 of whom, of which 及 of whose 连用。限定词大多放在 of which / whom / whose 前面，但在非正式文体中，有时候也可以放在其后面。

They picked up five boat-loads of refugees, some of whom had been at sea for several months. ( 或 ... of whom some ...) 他们救起了五船难民，其中有一些人已经在船上待了好几个月。

 所以，下面的句子都是正确的：

He has a lot of books, many of which are about African Americans. 

He has a lot of books, of which many are about African Americans.
