定从里正常语序,介词是在动词后面的。在可以提前的前提下,这个介词你可以提前,也可以选择不提前,提前的原因有:
一,不同说法而已,意思不变。
二,平衡句子结构,有时候从句过长,拖一个或更多的介词不好看。
还有不能够提前的情况,这种限于固定搭配联系紧密的词组,拆开可能意思有变化。比如look for, look after此类。追答非常认真地回答了你的两个问题,满意请采纳呐。

介词 + 关系代词”引导的定语从句
介词加关系代词引导的定语从句要注意以下几点:
1.“介词 + 关系代词”引导的定语从句时,介词的宾语只能用which(指物)和whom(指人),即:介词+which/whom。不能用that 和who。
e.g. This is the teacher from whom we’ve learned a lot. 这就是从他那里我们学了很多东西的老师。
Great changes have taken place in the city in which we live. 我们所居住的城市发生了巨大的变化。
2.有时介词也可放在从句的末尾,这时关系代词可用which/that(指物),who/whom/that(指人),也可以省略。
e.g. The situation (which/that ) we had got into was very dangerous. 我们当时的处境很危险。
The man (whom/who/that) you were talking to just now is my English teacher. 你刚刚和他谈话的那个人是我的英语老师。
3.当定语从句中的谓语动词短语是固定搭配,不可分割时,那么动词短语中的介词不能前置。
e.g. This is the pen which I’m looking for. 这是我正在找的那支钢笔。
不能写成:This is the pen for which I’m looking.
4.定语从句也可由“名词/代词/数词+介词+which/whom”引出。
e.g. That old man has two sons, one of whom is a doctor. 那个老人有两个儿子,其中一个是医生。
The house, the windows of which ( = whose windows = of which the windows) were damaged, has now been repaired. 窗子遭破坏的那栋房子现在已经修好了。
5.引导定语从句的关系副词(when, where, why) 可以用“介词+关系代词”代替。
e.g. I’ll never forget the day when I joined the party. (when= on which). 我永远都不会忘记入党的日子。
The factory where my father works is in the east of the city. (where = in which). 父亲工作的那家工厂在城东。
None of us know the reason why Tom was absent from the meeting. (why = for which). 我们都不知道汤姆缺席会议的原因。
6.“复合介词短语+which”引导的定语从句,常与先行词用逗号隔开,而且定语从句常用倒装语序。
e.g. He lived in a big house, in front of which stood a big tall tree. 他住在一幢大房子里,房前有一棵大树。
