定义：在复合句中作宾语的句子叫宾语从句。
宾语从句在中考中有三大考点：连接词、语序和时态
宾语从句部分是陈述句的时候，用that引导，that大部分情况可以被省略，如：I don’t know. He is a good student. ➨I know (that) he is a good student.
That不能省略情况：
1.双宾语I can’t tell him that the story is true.
2.插入语Just then I noticed, for the first time, that our teacher was wearing his coat.
3.句中有that he said (that) you were too young to understand the matter and that he was asked
not to tell you
b .宾语从句部分是一般疑问句的时候，用if或whether引导，如：I want to know，从句部分Is his answer right?这时用作宾语从句，需要先改为陈述句his answer is right,并在前边加上if或whether，即：I want to know if/whether his answer is right.
只用whether:
1.与or 或or not连用
I wonder whether we stay or whether we go.
Let me know whether he will come or not.
2.介词后
We’re talking about whether we can finish the work.
I’m interested in whether he likes English.
3.不定式
He hasn’t decided whether to visit the old man.
I don’t know whether to go
c．宾语从句部分是特殊疑问句的时候，直接用特殊疑问词引导，但一定注意将特殊疑问句的语序改为陈述句语序I want to know. When will we go? ➨I want to know when we will go.
练习：将下面句子组成一句。
My mother tells me, “The news isn’t true”.
He asks me, “what are you doing?”
He asked me, “ Will you go to school tomorrow or not?”
时态
宾语从句时态考点归纳为三句话：主过，从过；主不过，从随意；从真理，一般现在永不变。
1. 主不过，从随意：当主句不是过去时的时候，从句该用什么时态就用什么时态，不受限制。
He tells me that he was back yesterday.
I wonder if you will come next year.
2.主过，从过：当主句是过去时的时候，从句要改为过去的对应时态，如：I know you're right.当
主句变为过去时的时候，从句要把are改为were，即I knew you were right.
I really wanted to know what you had done.
I saw he was playing basketball.
3.从真理，一般现在永不变：当从句是客观真理的时候，无论主句是什么时态，从句一律用一般
现在时，如：My mom told that Beijing is the capital of China.
Grandpa told us that the earth moves around the sun.
含有宾语从句的复合句在一定的条件下可以转换为简单句：
1.当主句的主语或宾语与从句的主语一致，疑问词引导的宾语从句可以变成“疑问词+动词不定时”
I don’t know how I should do it next ➨I don’t know how to do it next.
2.当主句谓语动词是see, hear, watch等时，其后的that从句常简化为“宾语+动词原形或Ving”
I saw some boys were playing basketball on the playground just now. ➨
I saw some boys playing basketball on the playground just now.
3.当主句谓语动词是hope, agree, wish等时，当主句的主语或宾语与从句的主语一致，其后的that
从句可简化为动词不定时结构。
He agreed that he could help me with my English. ➨
He agreed to help me with my English.
1.I don’t know how I can get to the hospital.(改为简单句)
I don’t know get to the hospital.
2.Please tell me where we show our tickets. (改为简单句)
Please tell me show our tickets.
3.Rose doesn’t know when they are going to repair the watch. (改为简单句)
Rose doesn’t knowrepair the watch.

1.Are the children playing games? Tell me.
Tell me ______ the children ______ ______ games.
2．Have you finished your homework yet? Mr. Zhao asked Ma Gang.
Mr. Zhao asked Ma Gang ____ _____ ____ ____ ___ homework yet.
3．How many people can you see in the picture? Who knows?
