29.定语从句中的介词+关系代词结构
英语正式的文体,尤其是法律和科技文献中,定语从句中的关系代词(主要是which)前往往加介词,介词的选择有时取决于从句中的动词结构,有时又取决于主句中关系词前面的名词结构。因此介词的选择既要注意其后的也要注意其前的搭配关系。
Physics,about which I know nothing,doesn’t seem so dull a subject.(定语从句可以转换成I know nothing about physics,可以看出 about 与 know 有关。)
This depends on the purpose for which the examination is given.(定语从句可以转换成the examination is given for ... purpose,介词for与purpose有关。)
注意:在语义上相当于一个简单动词的短语动词中的介词不能前置,只能用在动词后。
This is a phase of history which it is sad to look back on.
The baby whom she is taking care of is very lovely indeed.
口语中要避免这种结构,关系代词which往往省略。
There’s a limit (which) nobody should go beyond.
That’s something (which) they can never put up with.
