In some places you may borrow as many books as you want ,but in other places <------>you are limited to a certain number ,<------->some may be novels.
A,where;which B,/;of them C,where;among which D,/;of which
能解一下吗
追答D
第一个括号前面有",but"了,不用再加连词了。
第二括号那里"Which"代替了a certain number of books,"of"表示"some may be novels"是包含在那些"a certain number of books,"里面的。
谢谢
