who 是什么从句?

是什么从句?

关系代词who引导定语从句,作句子的主语、宾语。定语从句由关系代词who、whom、whose、which、what、as和关系副词where、when、why等引导。 扩展资料
  关系代词who的具体用法
  1.who引导的定语从句的先行词是表示人的名词或代词。例如:
  (1)The student who is answering the question is John.
  正在回答问题的那个学生是约翰。
  (2)Anybody who breaks the laws will be punished.
  任何违反法律的#39人都将受到惩罚。
  2.who是主格,在定语从句中作主语,此时不能省略。例如:
  (1)The person who was here yesterday is a musician.
  昨天来这儿的那个人是位音乐家。
  在非正式英语中,who亦可作宾语,且可以省略。例如:
  (2)The man(who)I saw just now is Mr Li.我刚才见到的那个人是李先生。
  3.在定语从句中,who在人称、数上和其前面的先行词保持一致。如:
  Do you know the boy who is standing over there?
  你认识站在那边的那个男孩吗?
  4.若先行词中既有人又有物,关系代词用that而不用who。例如:
  He watched the children and boxes that filled the car.
  他看见了塞满汽车的孩子和箱子。
  5.若先行词前面有形容词最高级、序数词修饰,关系代词用that而不用who。例如:
  (1)Yao Ming is the best basketball player that I know.
  姚明是我知道的最好的篮球运动员。
  (2)Tom is the first boy that left the room.
  汤姆是第一个离开这个房间的男孩。

who在句子中间是什么句型?

who用作限制性或非限制性的关系代词,意思是“…的人,那个…”“他,她,他们”,在句中作主语。
如果被强调的成分是表示人的词,用who或that来连接都可以。如果是其它成分,则一律用that来连接。
如:. It is my mother who/that cooks every day.
It was yesterday that Tom passed in the maths exam.
who作为关系代名词(relative pronoun)怎样用 关系代名词本身有两个功用,它有代名词的功用,也同时具有连接词的功用
如:
That is the boy and he ate the apple.   就可以写成:
That is the boy who ate the apple.
当然,系关代名词的who是代表”人” 关系代名词有两种用,一种是限定用法,一种是补充用法(补充用法,会用逗号分开) 限定用法:关系子句是用来修饰先行词(Antecedent),
如: There were very few passengers who escaped without serious injury. 这句里是限定用法,who escaped without serious injury是用来修饰passengers,所以这句的意思是:未受重伤而逃出来的乘客绝无仅有
而 There were very few passengers
who escaped without serious injury. 这句是补充用法,who escaped without serious injury只是作资料的补充,而不是修饰passengers,所以这句的意思是:乘客非常少,而且他们没有受重伤
