高一英语定语从句语法
高一英语定语从句语法篇一
1)介词后面的关系词不能省略。
2)that前不能有介词。
3)某些在从句中充当时间,地点或原因状语的介词+关系词结构可以同关系副词when 和where 互换。例如:
This is the house in which I lived two years ago. 这是我两年前住过的房子。
This is the house where I lived two years ago.
Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?
Do you remember the day when you joined our club?
18.6 as, which 非限定性定语从句
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。As一般放在句首,which在句中。例如:
As we know, smoking is harmful to ones health. 如我们所知,吸烟有害健康。
The sun heats the earth, which is very important to us. 太阳使地球暖起来,这对我们人类很重要。
典型例题
1)Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句,不能用 that修饰,而用which.,it 和he 都使后句成为句子,两个独立的句子不能单以逗号连接。况且选he句意不通。
高一英语定语从句语法篇二
(一)定语从句一般由关系代词和关系副词引导
1、关系代词:who, whom, whose, which, that, as
2、关系副词:when, where, why
关系代词和关系副词必须位于从句之首,主句先行词之后,起着连接先行词和从句的'作用, 同时在从句中又充当句子成分。
e.g. She is the girl who sings best of all.(关系代词who在从句中作主语)
The comrade with whom I came knows French.(whom在从句中作介词with的宾语)
3、关系代词和关系副词的用法:1)当先行词为人时用who 作主语,whom作宾语;2)当先行词为物或整个句子时用which ,可作主语或宾语;3)先行词为人、物时用that ,可作主语或宾语;4)whose用作定语,可指人或物;5)关系副词when(指时间,在定语从句中作时间状语,where(指地点,在定语从句中作地点状语),why(指原因,在定语从句中作原因状语)。
(二)限制性定语从句与非限制性定语从句
1、限制性定语从句:从句与主句关系密切,去掉从句,主句意义不完整,甚至不合逻辑。
e.g. I was the only person in our office who was invited.(去掉定语从句,意思就不完整)
2、非限制性定语从句:从句对先行词关系不密切,去掉定从句,意思仍然完整。形式上用逗号隔开,不能that用引导。
