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.
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.
