定语从句介词+关系代词，介词如何选？

分两种：看从句（中的动词、形容词、名词）选介词、看先行词选介词

1）介词与定语从句中的动词构成固定搭配：

The girl with whom you work is his girlfriend. work with，表示“和……一起工作”。

2）介词与定语从句中的形容词构成搭配：

谓语部分中的形容词：He referred me to some reference books with which I am not very familiar. be familiar with sth.，表示“对……熟悉”。

定语的形容词：He is her son, than whom a kinder son does not exist. 这个句子原本应为：A kinder son than her son does not exist，意思是说“比她儿子更好的人是找不到了”，言外之意就是说她的儿子是最好的。所以，这里的介词than就是与定语从句中作定语的形容词kinder构成了呼应搭配。

3）介词与定语从句中的某个名词构成搭配：

I am sending you an inquiry, to which your prompt attention is highly appreciated. to与定语从句中的名词attention构成固定搭配attention to。

Many hypersomniacs suffer from narcolepsy, for which the primary symptom is excessive daytime sleepiness. symptom for，表示“是……症状”。

4）看先行词选介词

Mr. Zhang cracked the complex sentence with ease and the ease was unbelievable.

→The ease（Mr. Zhang cracked the complex sentence with ease） was unbelievable.

→The ease（Mr. Zhang cracked the complex sentence with which）was unbelievable.

→The ease（with which Mr. Zhang cracked the complex sentence）was unbelievable.

with ease表示“熟练地，轻而易举地” 这个句子的意思就是“张老师能够轻而易举地分析这个复杂的句子。这种轻松程度让人难以置信”。

同理：About a thousand species of animals are in danger of extinction. They are being destroyed at this rate and the rate has increased.

→The rate （they are being destroyed at this rate） has increased.

→The rate （they are being destroyed at which） has increased.

→The rate （at which they are being destroyed） has increased.

看先行词选介词，常见的搭配有：with ease, at the rate, in the direction, to the extent, to the degree, at the temperature, by the means, by the mode, in a culture, in practice等等。
