关系代词前介词的确定的3种规律第1种是 根据从句种动词的逻辑关系
不止三种喔~这里有篇文章概括得很好：
一、根据定语从句中的线索来选用介词,这线索可以是：
定语从句中的短语动词：这是主要线索,所选介词需与动词搭配.例如：
1）He bought much furniture,on which hespentalmost all the money he saved every month．他买了好多家具,把每月积蓄的钱几乎都花在这上面了.
2）The bodies on which the forces act are in equilibrium．受到许多力作用的物体处于平衡状态中.
3）The teacher for whom you are waiting is coming．你等的那位老师来了.
2．定语从句中的形容词短语：所选介词与形容词构成短语.例如：
1）The metals with which we are most familiar are steel and iron．我们最熟悉的金属是钢和铁.
2）It is the dictionary in which we are interested．这就是我们感兴趣的那本字典.
3）Partly because of his influence in politics,Ronald is a man with whom you will be glad to be acquainted．罗纳德是你很乐意结识的人,部分原因是由于他是个在政界有影响的人.
定语从句中的短语介词：所选介词是短语介词的组成部分.例如：
1）Sound is a tool by means of which people communicate ideas with each other．声音是人们交流思想的工具.
2）The property by virtue of which a bodytends to remain in either of natural statesis called inertia．使物体趋向于保持其所处的任一自然状态的性质称为惯性.
定语从句中的名词：所选用介词要求与名词搭配.例如：
1）Iam sending you an inquiry,to which your prompt attention is highly appreciated．兹寄去询价单一张,望尽快办理,不胜感激.
2）We meet with the difficulty of rebuilding the inner cities,to which top priority should be given．我们面临应该优先重建城内旧中心区的难题.
二、根据先行词来选用介词.所选用的介词与先行词构成固定搭配.例如：
1）We are not conscious of the extent to which work provides the psychological satisfaction that can make the difference between a full and an empty life．我们没有意识到工作能在多大程度上给人们带来心理上的满足感,而这种满足感正是区分充实生活与空虚生活之所在.
2）The ease,for example,with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines．比如,在自动化生产要求机器24小时不停地运转的行业里,人们由白班倒到晚班能否很快适应的问题越来越引起重视.
三、固定的介词短语.
在英语中,熟悉一些固定的介词短语,即可正确选用介词.如：in one's honor ／in whose honor,in this（that）case ／in which case,with one's help ／with whose help等等.例如：
1）We extended our warm welcome to the vis- iting delegation in whose honor a grand banquet was given．我们举行盛大宴会热烈欢迎代表团的来访.
2）He might be in bed still,in which casewe can go without him．他可能还没有起来,这样咱们就不带他去.
四、表示所属关系时用介词of.
在此结构中的介词可能是表示“所属”意义的介词of,其中of前常惯用表示“部分”含义的名词、代词或数词,如：one,a few,several,some,any,either,neither,none,half,the larger,the smallest等.即构成“名词（代词或数词）＋of＋关系代词”结构,of的前与后是部分与整体的关系.例如：
1）The lightest element is hydrogen,the atom of which consists of a nucleus of only one proton,round which revolves one electron．最轻的元素是氢,其原子由仅含一个质子的原子粒组成,有一个电子绕着这个核子转动.
2）Both players,neither of whom reached the fi- nal,played well．两名选手都打得很好,尽管谁都没有取得决赛权.
3）The treasure,some of which has been recov- ered,has been sent to the British Museum．那批珍宝,其中有一些是失而复得的,已经送到大英博物馆去了.
