for which,on which,in which,when,where的用法的区别及各自的意思.

谈谈“介词+关系代词”的用法\x0d一、用法说明\x0d介词+whom只能指人；介词+ which只能指物.如：\x0dLook,there comes Tom,for whom I have waiting for an hour.瞧,汤姆来啦,我等他等了一个小时.\x0dLast Saturday evening,I went to Wu Dong’s birthday party,in which I met a foreigner named Jim.上周星期六的晚上我去参加了吴东的生日聚会,在会上我会到了一个叫吉姆的外国人.\x0dShe came into the house,on whose wall there was a portrait of Einstein.她进入了房间,房子的墙壁上有一张爱因斯坦的画像.\x0d二、注意事项(1)有时,前面的介词可移到定语从句的中间或后面,此时whom可用who,that代替；which可以用that代替.而且who,whom,which,that都可省略.如：\x0dThe man with whom you talked just now is our manager.—The man who you talked with just now is our manager.你刚才与他谈话的那个人就是我们的经理.\x0dHe handed me a pen,with which I wrote down my address for him.—He handed me a pen,which I wrote down my address with for him.他递给我一支钢笔,我就用那支钢笔给他写下了我的地址.\x0d(2)当先行词是时间、地点、原因从句时,介词+ which一般在定语从句中分别做时间、地点、原因状语,于是介词+ which可以分别用when,where,why代替.但若介词+ which不是作时间、地点、原因状语,则不能用when,where,why代替.如：\x0dLast week,I visited Shanghai,in which I have made several friends.—Last week,I visited Shanghai,where I have made several friends.上周我参观了上海,在那儿我叫上几个朋友.
