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.
30.分隔型定语从句
一般情况下，定语从句紧跟在它所修饰的名词或代词之后，但有时由于修辞和语法的需要，定语从句与它所修饰的先行词分开，这就是分隔型定语从句。它有以下几种情况。
（1）先行词+介词短语+定语从句
He is the only friend of mine who is not interested in music.
That was the most important day in my life that I can remember.
(2)先行词+主动态动词+定语从句
He laughs best who laughs last.(谁笑到最后谁笑得最好。)
The day will come when you will be proud of me.
（3）先行词+分词短语+定语从句
There is someone waiting for you outside who says he must see you personally.
There are few places left on earth where man hasn’t put his foot.(4)先行词+定语从句
He is one of those people I know who do not care about money at all.
That is the only film I’ve ever seen which uses that technique.
31.分隔型同位语从句
和定语从句一样，同位语从句一般紧接与之对应的名词，但有时也可分开。
The suggestion was made that they should be packed off at once in a special train.
Within a week or two he received a letter from the university that he had been accepted.
Both,Either,Neither
