高一从句知识点总结

各种从句的知识点 得分点
比如怎么区别用that which 还是who whom 还有in which at which of which

个人经验
1,从句的本质就是用一个句子来代替一个词。比如名词性从句就是用来当名词的。那名词有哪些作用呢?名词可以当主语,同位语,表语所以才有了什么主语从句之类的。
2.从句性质主句决定,比如一个句子缺了主语那就选择名词从句,如果缺了定语(形容词)就用形容词从句。
3,连接词由从句绝定,从句再怎么样都是一个句子,所以连接词就要根据从句来确定,看从句是缺意思还是缺成分,至于各种连接词有什么作用就靠你自己查阅了。
4,有主句才有从句。要选择从句就要先分析主句的成分。这个就要靠练习了。
PS:1定语从句(形容词从句)最好的方法就是带入法,因为它的作用是形容词就是说一定要有个名词来修饰所以把从句修饰的词带入从句,那个词在从句中做什么成分或表达什么意思就是连接词表达的成分和意思。
2一般来说确定了名词从句答案就是what,除了同位语从句,还有我记得有一次的高考用的which是因为从句的意思是问两个队哪个队可以获胜,这就是有选择性所以用WHICH这也就解释了为什么定语从句不用what,因为定语从句是给定的名词是有选择性的。
3,同位语的判断,主句完整,从句完整,而且有个抽象名词需要解释(比如消息,时间这类你不解释别人无法明白内容的词)就选择that!只有一种特殊的就是I HAVE NO IDEA(我不知道)这个就当成一般的名词从句做,如果一般考试考到了就不要选择that因为那是考官用于迷惑你上当的!
祝你在英语上取得好的成绩

老师思路分析:

从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。

主语从句用作主语,如::

That the earth is round is true. 地球为圆的是真实的。

宾语从句用作宾语。如:

Do you know where he lives?

表语从句用作表语,如:

My opinion is that you should not go alone. 我的意见是你不应单独前往。

同位语从句用于解释说明前面的名词。如:

The fact that the earth is round is true. 地球是圆的的事实是真实的。(that从句用于解释说明the fact)

定语从句相当于一个形容词,用于修饰前面的名词。如:

The student who answered the question was John. 回答问题的学生是John.

状语从句相当于一个副词,如:

When it rains, I usually go to school by bus. 天下雨时,我通常坐公共汽车上学。(时间状语)

If he comes tomorrow, you will see him. 如果他明天来,你就可以看见他。(if 引导的条件状语从句,其结构为:if +状语从句,+主句)。要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来。

主句和从句的划分方法是相同的。句子的成分从谓语动词处来划分比较容易。谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语。如:

I am a teacher. 其中,I 是主语,am是谓语,a teacher 是表语。

He likes playing football very mucy. 其中,he是主语,likes是谓语,playing football是宾语,very much是状语。
