一道高一英语题：shebough many books yesterday,______many werewritten in english

是非线性定语从句。

原句：She bought many books yesterday. Many of the books were written in English.

合并：将yesterday提到就容易看出来了：Yesterday she bought many books, many of which were written in English.

如果选which，后面就不能有many，不然定语从句中就有which和many两个主语了。

many of the books were written in english

原句：
......many of them were written in eglish.....所以有of
不然的话就是many them were written ........显然错误

shebought many books yesterday,of which many were written in english.
she bought many books yesterday and many of them were written in english.

many of the books were written in english
所以选 of which

A
是啊，你看：
如果没有many，那么就用which,即
she bought many books yesterday,which were written in english.

但这里有many,而many的总范围是the books,
恢复原句是 many of the books were written in English.
所以用of which.
