試題分析：“介詞 + which / whom”引導(dǎo)的定語從句
關(guān)系代詞在定語從句中作介詞的賓語時，常常將介詞前置于作賓語的關(guān)系詞前，
I love the music that I can dance to. =" I" love the music to which I can dance.
The man who I talked to just now is my brother.=" The" man to whom I talked just now is my brother.
介詞后面的關(guān)系詞指人時只用whom, 不能用who或that; 指物時只用which,不能用that.
注意，并非所有情況下介詞都可以前移，含有介詞的短語動詞不可拆開，介詞仍需放在動詞后面，如：look for, look after, take care of等。
“介詞+ which / whom”前還可以用some, any, none, all, both, neither, many, most, each, few等代詞，名詞或數(shù)詞等。
His sons, both of whom loved music very much, spent most of their money on CDs.
The house, the roof of which is blue, will be used as a library.
whose的用法：
指代人或物，在從句中作定語，表示“他/它的”：We all dislike the boy whose father is a manager.
這里也可以用whose roof；whose+名詞=the+名詞+ of which=" of" which the名詞，故選C。
點評：本題難度適中。
即學(xué)即練：He is using a desk _______ are not of the same length.
A. whose  legs  B. the legs of whose   C.  legs of which   D. which legs
解析：A 。句意：他正在用一張桌腿不一樣長的桌子。
