语法精讲
当关系代词在定语从句中作介词的宾语时,我们通常用“介词+关系代词”引导定语从句。如果指人,用“介词+whom”;如果指物,用“介词+which”。
一、“介词+关系代词”的几种常见结构
1.“介词+which”在定语从句中分别可作时间、地点和原因状语,代替相应的关系副词when,where和why。
I often think of the moment at which (=when) I saw the UFO.
我常常想起我看见不明飞行物的那一刻。
餐厅可以在菜单上提供音乐选择和各种食物选择,给顾客更好的就餐气氛。
The reason for which (=why) Youth is very popular among students is that it carries a large amount of encouraging articles.
《青年报》在学生中很受欢迎的原因是它刊登了很多鼓舞人心的文章。
Restaurants can offer a choice of music along with the various food choices on the menu,giving customers a better atmosphere in which (=where) they are dining.
2.“代词/数词+of+which/whom”引导定语从句。
这个结构中,代词常常为all,each,one,many,much,most,some,none,both等,“代词+of+which/whom”通常在定语从句中作主语,说明整体中的一部分。有时候也可把“of+which/whom”置于代词或数词前。
He has lots of hobbies,one of which is swimming.
他有很多爱好,其中之一是游泳。
The old man has three sons, all of whom care about him.
那位老人有三个儿子,他们都很关心他。
3.“the+名词+of which/whom”引导定语从句。
这个结构中,of which/whom充当定语,修饰前面的名词,整个结构相当于“whose+名词”引导的定语从句。
On the blackboard the teacher wrote a sentence,the meaning of which (=whose meaning) I don’t understand.
老师在黑板上写了一个句子,句子的意思我不明白。
4.“the+形容词比较级(最高级)+of+which/whom”引导定语从句。
There are two buildings,the larger of which stands nearly a hundred feet in height.
这儿有两座建筑物,较大的那座几乎有100英尺高。

二、关系代词前介词选择的原则
1.根据定语从句中的谓语动词或形容词和介词的搭配关系选择。

黑猩猩会查看自己是否得到了想要与之交流的动物的注意。
2.根据定语从句中介词与先行词的搭配关系选择。
Many lessons are now available online,from which students can choose for free.
许多课程现在都可以在网上找到,学生们可以从中免费选择。
3.根据句子的意思选择。

我写这封信是为了表达我对你的感激之情,没有你的帮助,我的英语就不会有很大的进步。
