初中英語賓語從句講解
一、 賓語從句的概念
賓語從句屬於名詞性從句，在句中作主句的賓語。
eg. we know mr. green teaches english.
she asked if these answers were right.
二、賓語從句三要素
引導詞（連線詞） 語序時態
三、重難點掌握
（一）引導詞
1． 由從屬連詞that引導的賓語從句
由從屬連詞that引導的賓語從句
注：that 在句中無詞彙意義，在從句中不能充當成分，在口語當中往往省略
i hear (that) you passed the exam.
2. he said (that) his father was a singer.
3. the teacher told us (that) the sun rises in the east.
2． 由從屬連詞 whether, if 引導的賓語從句（重點掌握）
由從屬連詞whether, if 引導的賓語從句
if/ whether 「是否」，說明對陳述的事物不明確或不清楚。常用在ask, wonder, can(could) you tell me 等後。
1. i want to know whether/if he is right.
2. i ask him whether/if he likes me_.
3. i wonder _whether/if we can get there.
4. could you tell me whether/if that film is interesting ?
◆只能用whether不能用if的情況
1.在介詞後面：
i』m thinking of whether we should go fishing.
we are worried about whether it will rain tomorrow.
2.在動詞不定式前：
they asked me whether to go skating.
3.當與or not連用，或提出兩種選擇時:
i don』t know whether he』s free or not.
mary asked whether i was doing my homework or not.
tell me whether you』d like to go shopping or tidy the room.
4.賓語從句提前時：
whether this is true or not, i can』t say.
3．由連線代詞 who,whom,whose,which, what和連線副詞 where,how,why,when引導的賓語從句。
這些代詞或副詞連線主句和從句，並在從句中擔任句子成分，具有一定的意義，不可省略。
1. he asked who the man is.
2. do you know whose book it is?
3. he asked what he could do for that.
4. do you know which answer is the best?
5. please tell me where the right way is.
6. can you tell me how we can get there?
7. could you tell me when we should meet?
（二）語序：陳述句語序
即：主句+連線詞+從句（主+謂+其他成分）
do you remember他多大歲數)?
當從句的原句為以下句子以及what, who作主語時，語序不變：
what』s wrong?
what』s the matter?
what』s happening?
what happened?
eg :i don』t know what』s the matter.
can you tell me who is over there?
（三）時態：
1、主句用一般現在時，現在進行時或一般將來時等「現在」範疇的時態時，從句的時態根據需要來用，不受主句影響。
i want to know what time he got up this morning.
he will tell us that he has been able to look after himself.
they are saying that they really like this city.
2、主句用過去時，從句用與過去相關的時態。
kate said there was a box under the desk.
they asked what he was doing then.
she asked whether i had seen her before.
3、從句說明的是一般真理、客觀事實、自然現象、名言時，仍用現在時。
dad told us that it is better to do than to say.
he told the boy that three and three is six.
he told me the earth moves around the sun.
4、從句中有具體時間狀語，即使從句動作發生在主句動作前，仍用一般過去時。
the teacher told me she was born in 1960.
