同学们,2017年中考马上就要来临,在这短短几个月的时间里,我们要好好把握三轮复习这一利器,做好适合自己的学习计划，有起码的安排和目标的制定，这关系到同学们能否利用有限的时间取得最大的收获,使我们的成绩更上一层楼。这个计划要“大”“小”结合，既要有分阶段的整体计划，又要有很具体的每天计划。安颖老师建议同学们每天晚上睡前就想好第二天的复习内容，越具体越好，例如要解决英语中的哪一个知识点，如何解决，这样就可以避免盲目复习导致的徒劳无功。
复习的方法多种多样,不同的方法适用于不同的人,我们要在实际运用中找到适合自己的复习方法。以不断提高复习的效率。同学们,只要大家合理安排好复习时间,运用恰当的复习方法,相信大家一定会在中考中取得理想的成绩。今天安颖老师就针对从句这一知识点给同学们做一个详细的梳理.
根据从句在句中的句法功能，从句可分为名词性从句、定语从句和状语从句。
1、 名词性从句, 细分又分为主语从句,宾语从句,表语从句和同位语从句
（1） 主语从句
What he wants is his mother’s love.
（2）宾语从句
I don’t know how to answer the question.
宾语从句是初中很重要的语法点,同学们在复习宾语从句时一定要把握两点,即宾语从句的陈述语序与时态一致问题.
（3）表语从句
This is why I came here.
（4）同位语从句
I have no idea where he born.
2、定语从句
引导定语从句的关系代词有who, whom, whose, which, that, as,和关系副词when, where, why。
关系词 先行词 从句成分
关系代词 who 人 主语
whom 人 宾语
whose 人，物 定语
that 人，物 主语，宾语
which 物 主语，宾语
as 人，物 主语，宾语
关系副词 when 时间 时间状语
where 地点 地点状语
why 原因 原因状语
（1）在下列情况下，要用that而不用which。
a. 先行词有all, everything等不定代词时，如，

b. 先行词被all, every, no, some, any, little, much等修饰时，如，

c. 先行词被序数词或形容词最高级修饰时，

d. 先行词被the only, the very, the same, the last修饰时，如

Hangzhou is a city which/that has a beautiful lake.
We don’t know the reason why he was late yesterday.
The reason which/that he gave was reasonable.
（3）as和which
as 可以放于句首，而which 不可以, 如果有“正如，象”的含义，并可以放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。
They won the game, as we had expected.
They won the game, which we hadn’t expected.

（4）three of them 和three of which

3、状语从句
在复合句中起状语作用的从句叫做状语从句。状语从句可分为时间状语、地点状语、原因状语、目的状语、结果状语、条件状语、行为方式状语、比较状语、让步状语等多种。
