宾语从句复习研讨
复习目标:
1.宾语从句的概念
2.宾语从句的引导词,语序及时态变化。
Step 1---概念
观察下列句子,判断哪些是宾语从句?
1.I like my teacher.
2.I enjoy playing basketball.
3.I decide to study hard.
4.I know him.
5.I know Mr Li teaches English.
6.She asked if the answer was right.
总结:
宾语从句即句子作宾语,而不再是一个词或短语。
1.(名词作宾语)
2.(动名词作宾语)
3.(不定式作宾语)
4. (代词作宾语)
5. (句子作宾语)
6.(句子作宾语)
Step 2 ---引导词
He is a boy.
He is in the park.
He is jumping.
怎样把上边的句子变成宾语从句呢?
I see
总结:从句是陈述语气时,引导词用that.
that在句中无意义,不充当成分,可省略。
he is a boy.
(that) he is in the park.
he is jumping.
Is he 10 years old
Is he a student in Grade 3
Is he from China
怎样把上边的句子变成宾语从句呢?
Step 2 ---引导词
I wonder
he is 10 years old.
if / whether he is a student in Grade 3.
(是否) he is from China.
总结:从句是一般疑问语气时,
引导词用if 或 whether 。
What’s his name
Where does he live
When was he born
怎样把上边的句子变成宾语从句呢?
Step 2 ---引导词
Do you know
what his name is
where he lives ?
when he was born
总结:从句是特殊疑问语气时,引导词用特殊疑问词。
Practise
给下列句子填上正确的连接词。
whether where how if that
1.He said ______he missed his mother very much.
2.I don’t know ________ he will go to the park with me.
3.Can you tell me ______ he is ?
4.I don’t know _________ it’s going to rain or not.
5.Do you know _______ I can go to the hospital.
that
whether / if
where
whether
how
注意:当句末为or not时,引导词只能用whether,不能用if.
补充:
I haven’t decided whether to go there.
(在不定式前引导词也只用whether,不用if.)
Step 3--- 语序
Step 4 ---时态
1. I hear (that) Jim _______(be) a worker one year ago.
Jim ______(run) in the park every morning.
Jim _________(cook) dinner for us tomorrow
Jim ____________(sing) a popular song now.
Jim __________(be) to the Great Wall twice.
总结:
1. 当主句的谓语动词是一般现在时,
宾语从句的时态不受主句时态限制,
根据句意选择合适的即可,简称主现从任意。
is singing
runs
will cook
was
has been
2. He said he _____(be) sick last week.
he _________ (watch) TV at 7:00 yesterday.
was
was watching
总结:
2. 当主句的谓语动词是一般过去时,宾语从句则使用相应的过去时态,简称主过从必过。
Step 4 ---时态
3. My father said he is forty years old.
The teacher said that there are four seasons in a year.
My mother often says eating breakfast is good for our health.
总结:
3. 如果宾从所表达的内容是客观真理或客观事实时,从句不受主句时态影响,就用一般现在时,简称从句客观永一现。
Step 4 ---时态
Practise
1. The radio says it _________ cloudy tomorrow. (be)
2.Tom says that they __________(play)basketball at six o'clock yesterday evening.
3. I didn't know what time he _______ the letter. (write)
4. Miss Wang told me that the earth _____(move)round the earth.
5. Our teacher told us in class the sun_____ east. (rise)
will be
were playing
wrote
moves
rises
1.主现从任意
2.主过从必过
3.从句客观永一现
总结
陈述句
一般疑问句
特殊疑问句
注意事项
1.一般而言,宾语从句的否定式与一般句子的否定式是一样的。但若主句谓语动词是think、expect、believe、guess、imagine suppose等表示“认为,猜想”的词时,一般要把宾语从句中的否定式转移到主句中。
e.g:I don't think it's going to rain.
I don't believe she will lend you the money.
2.could/would是委婉语气,而不是过去式,因此宾语从句的时态根据实际情况用不同时态。
Could you please tell me where we show our tickets
Could you tell us which gate we have to go to
Would you like to know when he will come back
