从句引导词是什么
从句引导词通常指的是用于引导从句的单词或词组;当然,在某些情况下,引导词是可以被省略的。正如并列连词是并列关系的重要提示,引导词则是主从关系的重要线索。
引导词是英语语法中的专有名词。引导词就是引导从句的词,比如whether,how,what ,why,if,when等具有引导紧贴后面从句功能的词。
引导词结构:
在“one of+复数名词+定语从句”结构中,从句的谓语动词应与复数名词保持一致;当one前有the only修饰时,从句的谓语动词应与the only one保持一致。如:
He was one of the students who were late for class.
He was the only one of the students who was late for class.
引导词前有介词或短语介词时,修饰人只能用 whom,修饰物只能用which引导,如:
My glasses,without which I was like a blind man, fell to the ground and broke.
The man,by whom the wolf was shot,is called Jackson.

定语从句能有哪些引导词它们的区别是什么举些例子
定语从句引导词分1)关系代词:who,whom,which,that,whose
2)关系副词:when,where,why
3)as也可以做关系词:
关系词的选择,依据两种情况来决定:
1.看先行词(被定语从句修饰的词),先行词是“人”还是“物”,是“物”可能用which,that,whose,where,when,why等;先行词是“人”可能用who,whom,that,whose等
2.看关系词在定语从句中所担任的句子成分,1)先行词是“物”,关系词在定语从句中做主语,可以用that,which.比如:The dog that \ which won the race is John’s.比赛获胜的那头狗是约翰的.(先行词是“物”dog,关系词that\which在定语从句中作主语,won是谓语)
关系词在定语从句中做宾语,可以用that,which也可以省略,比如:
The letter(that \ which) I received yesterday was from my brother.我昨天收到的那封信是我兄弟寄来的.(先行词是“物”letter,关系词that\which在定语从句中做received“收到”的宾语)
先行词是“人”或“物”,关系词在定语从句中做定语,用whose引导定语从句:
That is a book whose cover is blue.那是一本封面是蓝色的书.(先行词是“物”book,关系词whose在定语从句中做定语修饰cover)
He is the man whose car was stolen last night.他就是昨晚车子被盗的那个人.(先行词是“人”man,关系词whose在定语从句中做定语修饰car)
3.先行词是地方,关系词在定语从句中做地点状语,用where
先行词是时间,关系词在定语从句中做时间状语,用when
先行词是reason,关系词在定语从句中做原因状语,用why(也可以省略或that)
I know a place where we can swim .我知道一个我们可以游泳的地方.(先行词是“地方”place,关系词在定语从句中做地点状语修饰swim)
I’ll never forget the day when we first met.我永远也忘记不了我们第一次见面的那一天.(先行词是“时间”day,关系词when在定语从句中做时间状语修饰met)
The reason why \ that he failed was his laziness.他失败的原因是他的懒惰.(先行词是“物”reason,关系词why或that在定语从句中做原因状语修饰failed)
定语从句比较复杂,不是一句两句能说明白的,你还得系统的学习才能掌握.
