宾语从句三要素
01. 引导词
02. 语序
03. 时态
一、引导词
【例句】
1. I think (that) math is difficult.
She said (that) she would leave a note on the desk.
【结论】
陈述句作宾语时，宾语从句用that引导。that只起连接作用，没有实际意义，在从句中不充当成分，因此常可省略。
(1) 由that引导的宾语从句
宾语从句结构I:
主语+谓语动词+that+宾从(肯定句、否定句)
I think that the Water Festival is not fun.
主语
谓语
宾语从句(否定句)
Bill thinks that the races were interesting to watch.
宾语从句(肯定句)
主语
谓语
宾语从句的引导词
that，它在句中无词义，在从句中不做成分，在非正式文体中可以省略
(2)由if / whether引导的宾语从句
宾语从句结构II:
主语+谓语动词+ whether/if+宾从(一般疑问句，陈述语序)
宾语从句的连词
whether/if 表示“是否”，不可省略
由于if和whether连接的句子在语义上是一般疑问句或选择疑问句，要注意把从句语序改为陈述句语序。主+谓
把下面两个句子改为含有宾语从句的复合句。
1. Is Jim a good student I don't know.
2. Does Kate get up early Do you know
I don't know whether/if Jim is a good student..
Do you know whether/if Kate gets up early
练一练
一般来说，在宾语从句中if与whether可以互换使用。但在特殊情况下，两者不能互换。
只能用whether，不能用if引导的情况：
1) 在介词的后面
e.g. I’m thinking of whether we should go to see the film.
2) 与or not直接连用
e.g. I don’t know whether or not they can get there on time.
I don’t know whether or not he will come.
如果or not放在whether所引导的从句句尾，可用if 替换。
I don’t know whether/if he will come or not.
注意whether和if的使用区别
a.当whether后紧跟or not时，不用if.
b.介词后面的宾语从句不能用if.
I worry about whether I hurt her feelings.
He asked me whether I wanted to go there by train or by bus.
c.在强调任意选择时，用whether…or，此时不用 if 替换whether。
Whether he will come I am not sure.
注意whether和if的使用区别
d. 虽引导宾语从句，但为了强调宾语部分，也可把从句放在句首，此时只用whether不用if。
e.句子中有if 引导的条件句，如再有表示“是否”的宾语从句，用whether不用if。
He asked me whether I’d move to New York if I got the job.
f. 如果宾语从句为否定句时，则只用if不用 whether。
I don’t know if it won't rain tomorrow.
“ Do you like the song ” she asks.
She asks whether/if I like the song.
Tom said. He is reading a book.
Tom said that he was reading a book.
一般疑问句
陈述句(人称变化)
陈述句
观察与发现
总结：
宾语从句一定用陈述语句。
即“引导词+主语+谓语+其他成分”
Would you please tell me
Do you still remember
I don’t know
Let’s match,talk and think.
What should I do
When is the book sale
Why did you come here
Where do you have your English lessons
例：Would you please tell me when the book sale is

He is reading a book .
He has finished his work.
He said
He had finished his work.
He would go to Hong Kong .

当主句是一般过去时的时候，宾语从句必须运用相应的过去的某一种时态，从而达到主句和从句的相互一致。

主过从四过！
宾语从句的时态

若主句是一般过去时，从句则用过去相关的时态

Read the passage below and underline the objective clauses.
Dear Xia Yu,
Do you know that there are two special days for parents in America One is Mother’s Day on the second Sunday of May, and the other is Father’s Day on the third Sunday of June. On these two days, American children often give gifts to their parents or take them out for lunch or mon gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is becoming more and more popular to celebrate Mother’s Day and Father’s Day in China. I wonder if children over there also give similar gifts to their parents. I believe that there are many ways to show our love. Actually, we don’t have to spend a lot of money. It is also a good idea to help parents to do something instead.
June
