Find out the Object Clauses
1. 由从属连词that引导的宾语从句
e.g. 1) I hear (that) he will be back in an hour.
2) He said (that) he missed us very much.
注：that 在句中无词汇意义，在从句中不能充当成分，在口语当中往往省略。
1. 在主+谓+it(形式宾语)+宾补+that 从句(真正宾语) 的句型中不省略。
eg: We must make it clear that we mean what we say.
2. 由连词and连接的两个由that引导的宾语从句中,第二个that 不省略。
that在宾语从句中的省略与保留
eg: He told me (that) he would come and that he would come on time.
3. 当that作介词except, in等宾语时
e.g. They believe in that she must still be single.
I know nothing about him except that he is
living in Beijing.
2. 由从属连词whether, if引导的宾语从句
if/whether 引导宾语从句 表示“是否”
if/whether可互换, 但whether … or not为固定搭配.
I want to know if/whether she is right.
They didn’t know whether Tom could come back or not.
1) whether和if都可以引导宾语从句
e.g. I don’t know whether or not he will come.
注意：如果or not放在whether所引导的从句句尾，则可以用if来替换。
I don’t know whether/if he will come or not.
e.g. I worry about whether I hurt her feeling.
whether和if的使用区别
1. 当whether后紧跟or not时,不用if
2. 介词后面的宾语从句不能用if
He asked me whether I wanted to go there by train or by bus.
他问我是想乘火车还是坐公共汽车去那里。
注：whether和or一起还有“不管”之意, 引导让步状语从句。
Whether he drives or takes the train, he will be here on time.
不管开车来还是乘火车来，他都会准时到。
3. 在强调任意选择时,用whether … or,此时不用 if 替换whether。
e.g. Whether he will come I am not sure.
e.g. He asked me whether I’d move to New York if I got the job.
4. 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。
5. 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。
2) 引导主语从句置于句首时，只能用whether
e.g. Whether he comes or not makes no difference.
3) whether可以引导表语从句和同位语从句，if不可以
4) 用在动词不定式之前时用whether不用if。
I don’t know whether to go there at once.
我不知道是不是该立刻去那里。
3. 由连接代词 who, whom, whose, which, what 和连接副词 where, how, why, when引导的宾语从句
e.g.
1) Do you know whose book it is
2) Please tell me when we’ll have a meeting.
3) Could you tell me why the train is late
4) He asked who could answer the question.
2. 宾语从句中时态的变化
当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的意思来使用需要的任何一种时态。
I hear (that)
Jim went to work an hour ago.
he is interested in English.
she will come tomorrow.
Tom has been to London twice.
He will go to Hong Kong.
He is sick.
He is reading a book.
He has finished his work.
He said
He had finished his work.
He would go to Hong Kong.
He was sick.
He was reading a book.
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。
the sun is much bigger than the moon.
summer is after spring.
the earth moves around the sun.
He told me (that)
We knew (that)
The teacher told us (that)
当宾语从句说明的是客观存在的事实或者是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。
主句时态 从句时态
一般现在时、一般将来时、祈使句时 根据句意的需要用任意一种时态
一般过去时 与原句相对应的过去的时态
客观事实、真理、自然现象、名言警句、谚语等 一律用一般现在时
3. 宾语从句的语序
Danny says that he will learn English.
Do you know where he came from
Please tell me how I can get to the bus station.
无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。
宾语从句三要素
引导词
that+陈述句
if／whether+一般疑问句
特殊疑问词+特殊疑问句
时态
主句为一般现在时
主句为一般过去时
一般过去时
过去将来时
过去进行时
过去完成时
语序
宾语从句的语序都为陈述句语序
从句客观真理时态不变
从句可为任何时态
学习宾从三注意，时态语序和连词。
时态主从要呼应：
主句若为现在时，从句时态随句意；
主句若为过去时，从句时态变过去；
宾从若是表真理，时态不变无质疑。
语序要用陈述序，切莫照搬疑问句。
That 连接陈述句，省与不省要注意。
从句若表“是否”时，if/whether要慎记。
特殊问句作宾语，仍用原来疑问词。
三个问题需牢记，切莫丢东忘了西。

4b Read the passage below and underline the objective clauses. If possible, write your own sentences about Mother’s Day and Father’s Day using 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
