今天小编为大家归纳总结了中考英语必考点——宾语从句，此考点在中考中出现的频率非常高，大家要熟练掌握、灵活运用。
宾语从句(The Object Clause)在复合句中作主句的宾语。宾语从句通常由下面一些词引导。
1、由that引导(that在口语或非正式文体中常省略)。
2、由what , when , where, which, who, how ,why等连接代词或连接副词引导。
3、由连词whether或if引导(口语中常用if)。
应注意的几个问题：
1、宾语从句可放在形容词后。常用形式是“be+形容词+宾语从句”
e.g. I am glad you like it .
2、宾语从句与主句时态的一致。
1)主句是现在(或将来)时态时，宾语从句可根据实际需要用不同的时态。
如：He says Mary is playing with the cat .
He says Mary often plays with the cat.
He says Mary will play with the cat.
I think he left yesterday morning.
2) 主句时态是一般过去时，从句要用过去时态的某种形式。
He said Mary was playing with the cat.588.es
He said he hoped to be back soon..
3)当从句所表示的是客观事实或客观真理时，该从句都用一般现在时，不用过去时。
如：He said light travels much faster than sound.
3、宾语从句中的否定转移。如果主句谓语动词是think , believe suppose 等，而从句的意思是否定的，这时主句的谓语动词用否定式，从句用肯定式。如：
I don’t think you are right. 我认为你不对。
4、将普通的特殊疑问句变成宾语从句时，从句的语序要由疑问句变成陈述句的语序。
When will the meeting begin?-------I want to know when the meeting will begin.
5、将普通的一般疑问句变成宾语从句时，则用if /whether连接，同时变成陈述句语序。
Are you an English teacher ?-------He asked if I was an English teacher.
在下列情况下只能用whether
1)介词后的宾语从句 I’m thinking about whether we should go fishing.
2)宾语从句提前时 Whether this is true or not, I can’t say.
3)直接与or not连用时 I don’t know whether or not he was ready.
4)在带to 的动词不定式前 She hasn’t decided whether to go or not.
if也可引导条件状语从句，表示“如果”(主将从现，主过从过)。比较：
I don’t know if he will come. If he comes ,I will tell you.
6、在变宾语从句时，要注意以下几点。1)连接词 2)人称 3)语序 4)时态 5)标点
