〖思维〗1 . 形式不同.如： The house _______ windows face south is our reading - room . A . of which B . whose C . which D . its 此题正确答案是B,不能选择A.选择 of which 时应在名词前加上定冠词 the,也就是说如果名词前有 the 就只能用 ofwhich.如果名词前没有冠词,就用 whose.如上句题干改为：The house _______ the windows face south is ourreading-room . 此题就只能选择答案A而不能选择B了. 2 . whose 即可以指人,又可以指物,而 of which 只能用来指物.如： The boss in whose department looked down upon women . The house whose roof was damaged now has been repaired . 上面第一句不可用 of which 来改写,第二句可以.可写成：The house of which the roof was damaged hasnow has been repaired . 3 . of which 除了可以表示所属关系外,还可以用来表示整体的关系,而 whose 则不能. He borrowed a book of which the author was a peasant . In Barcelona the Chinese team got 16 gold medals , of which 12 were won bywomen . 第一句中的 of which 就可以用 whose 来代替.因为这个句子中 of 是用来表示所属关系.可改写成：He borrowed a bookwhose author was a peasant.而第二句中的 of which 就不要用 whose 来替.因为这个句子中的 of不是表示所属关系,而是表示整体与部分的关系. 4 . 引导非限制性定语从句多用 whose,而很少用表示所属关系的介词 of 加上关系代词 which.如： There is a mysterious lake at the foot the hill , whose depth has never been measured . 山脚下有个神秘的湖,其深度从未测量过. 如介词 of 不表示所属关系,而是用来表示整体与部分的关系.此时就经常引导非限制性定语从句了.如； There are 102 elements found in nature , of which most are metals . The stories about the Long march , of which this is one example , are wellwritten .
