沒有好的高一，必然沒有好的高考；沒有高一的危機感和緊迫感，就沒有高三的從容自信！

　　一.關系代詞的用法: 關系代詞指代先行詞

　　在定語從句中作主語

　　在定語從句中作動詞的賓語或者介詞的賓語, 介詞在后

　　指人

　　that / who

　　that / who / whom

　　指物

　　that / which

　　that / which

　　上表中黑框內的關系代詞可以省略; 在口語及非正式文體中whom常被who所替代; 另外, 關系代詞whose表示 “…(先行詞)的”

　　二.示例:

　　1.關系代詞在定語從句中作主語

　　a. Do you know the man that / who came to see Xiao Yang this morning ?

　　b. This is a book that / which tells about space rocket.

　　2.關系代詞在定語從句中作動詞的賓語

　　a. The comrade ( that / who / whom ) they came to visit is a scientist.

　　b. I will never forget the day ( that / which ) we spent in the countryside.

　　3.關系代詞在定語從句中作介詞的賓語, 介詞在后

　　a. This is the house ( that / which ) he was born in.

　　b. The person ( that / who / whom ) you should write to is Mr Ball.

　　c. The man ( that / who / whom ) you talked with is our English teacher.

　　4.whose引導的定語從句

　　a. I know a lady whose husband is a Nobel Prize winner.

　　b. The child whose mother died in the fire is now an engineer in our company.

　　c. He is living in a house whose windows are painted white.

　　三.應注意的問題:

　　1.指物時, 關系代詞只用that而不用which的情況:

　　①.先行詞被最高級或the only, the very, the same等修飾時

　　a. This is the best play that was written by Jack.

　　b. He is the only person that I can trust.

　　②.先行詞被序數詞或the last等詞修飾時

　　a. This is the first car that arrived this morning.

　　③.先行詞為all, everything, nothing, something, anything等不定代詞時或被不定代詞all, any, no等修飾時

　　a. All the people that come from the country work much harder.

　　b. This is all that I can tell you.

　　④.人+動物或事物共同作為先行詞時

　　a. My father and Mr Brown talked of things and persons that they remembered for about an hour.

　　⑤.句中又有which作為疑問詞出現時

　　a. Which is the train that goes to Beijing ?

　　2.關系代詞who, which, that在定語從句中作主語時, 要注意定語從句中的主謂一致問題. 因為who / that / which指代先行詞, 所以定語從句的謂語與先行詞保持一致即可

　　a. I came to get the book that was left in the classroom.

　　b. I came to get the books that were left in the classroom.
