高二这一年，是成绩分化的分水岭，成绩会形成两极分化：行则扶摇直上，不行则每况愈下。今天小编跟大家分享关于高中英语语法关系代词学习方法分享，希望对大家有所帮助。
一.关系代词的用法: 关系代词指代先行词 在定语从句中作主语 在定语从句中作动词的宾语或者介词的宾语, 介词在后，指人 that / who that / who / whom 指物 that / which that / which 上表中黑框内的关系代词可以省略; 在口语及非正式文体中whom常被who所替代; 另外, 关系代词whose表示 “…(先行词)的”
二.示例:
1.关系代词在定语从句中作主语 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.关系代词在定语从句中作动词的宾语 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.关系代词在定语从句中作介词的宾语, 介词在后 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引导的定语从句 a. I know a lady whose hus band 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.应注意的问题:
1.指物时, 关系代词只用that而不用which的情况: ①.先行词被至高级或the only, the very, the same等修饰时 a. This is the best play that was written by Jack. b. He is the only person that I can trust. ②.先行词被序数词或the last等词修饰时 a. This is the first car that arrived this morning. ③.先行词为all, everything, nothing, something, anything等不定代词时或被不定代词all, any, no等修饰时 a. All the people that come from the country work much harder. b. This is all that I can tell you. ④.人 动物或事物共同作为先行词时 a. My father and Mr Brown talked of things and persons that they remembered for about an hour. ⑤.句中又有which作为疑问词出现时 a. Which is the train that goes to Beijing ?
2.关系代词who, which, that在定语从句中作主语时, 要注意定语从句中的主谓一致问题. 因为who / that / which指代先行词, 所以定语从句的谓语与先行词保持一致即可 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.
