定语从句 关系代词

Answer 1

回答如下：
引导定语从句的关系代词有which，that，who，whom，whose，as 。
1. which指代事物、动物、婴儿，在定语从句中作主语、宾语。作宾语时，which可以省略(非限制性定语从句或介词提前时除外)。它引导非限制性定语从句时，可以指代整个句子。例如：
This is the house (which ) Lu Xun once lived in / in which Lu Xun once lived.
The baby which is crying is my daughter.
I am not interested in the job ( which) you are doing now.
He is ill, which is true.
2. that 指代人、物，在定语从句中作主语、宾语。that作宾语时可省略，但作介词宾语时，介词不能提前。that不能引导非限制性定语从句。例如：
The bridge that was built 50 years ago has been pulled down.
She is the doctor (that ) I mentioned yesterday.
The factory (that) he works in is very large.
3. who、whom指代人，who可以作主语、宾语; 而whom只能作宾语。作宾语时，二者均可省略，但介词提前时，只能用关系代词whom作宾语。例如：
The man who is standing there is my uncle.
The girl who / whom you want to know about / about whom you want to know.
4. whose 指代人、物，在定语从句中作定语。例如：
The girl whose father is a doctor is our monitor.
The book whose cover is red is mine.
We met with a boy, under whose guidance we soon found the girl's home.
5. as(像，正如) 指代人、物，在定语从句中作主语、宾语、表语,常用在such ...as, the same (... ) as短语中或非限制性定语从句中。它引导的非限制性定语从句可以置于句首、句中和句尾，可以指代整个句子。例如：
I don't believe such a person as you (are).
This is the same overcoat as you bought yesterday.
As (正如)we can see, he is a thief.
= He, as we can see, is a thief.
= He is a thief, as we can see.
