A. 初中英语宾语从句里连接词做主语的例句
we have to check what is in it
这不来还是陈述语自序吗.it在这里是in的宾语,in it是介词短语做表语.
比一比
we have checked out that the cat is in it
它们是一样的结构
B. 新东方中学英语试讲5分钟，宾语从句怎么讲比较好
亲：其实复就体现三点就行制。
陈述句 由连接词that引导，that可以省略。
一般疑问句 由if/whethe引导，后面跟的是陈述语序。
特殊疑问句 由wh-词引导，后面跟陈述语序。
每个要点给几个有代表的例句，能实践这个语法就行。
祝你成功！
望采纳，thx!
C. 宾语从句所有连接词例句 谢谢了！
简单来说就3点。
一、当由陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：
She
said
that
she
would
leave
the
message
on
the
headmaster’s
desk.
He
said
that
he
could
finish
his
work
before
supper.
二、当由一般疑问句充当宾语从句时，用if或whether引导，意为"是否"。如：
Alice
wanted
to
know
if/whether
her
grandmother
liked
the
bag.
I
don’t
know
whether
he’ll
come
the
day
after
tomorrow.
但直接与or
not连用时,往往用whether如：
Let
me
know
whether
he
will
come
or
not.(=
Let
me
know
whether
or
not
he
will
come
)
I
don’t
know
whether
he
does
any
washing
or
not.(=
I
don’t
know
whether
or
not
he
does
any
washing.
)
I
wonder
whether
we
stay
or
whether
we
go.
三、如果宾语从句原来是特殊疑问句，只需用原来的疑问词引导。如：
Could
you
tell
me
where
we
will
have
the
meeting
this
afternoon?
I
don’t
know
who
bought
the
present
for
me.
Is
it
Jack?
D. 初中英语的语法总结,特别是现在完成时和宾语从句!!!!
现在完成时的用法
have(has)+过去分词
1.现在完成时用来表示现在之前已发生活或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在.
I have lost my wallet.(含义是:现在我没有钱花了.)
Jane has laid the table.(含义是:已可以吃饭了.)
Michael has been ill.(含义是:现在仍然很虚弱)
He has returned from abroad. (含义是:现在已在此地)
2. 现在完成时可以用来表示发生在过去某一时刻的,持续到现在的情况,常与for,since连用.
Mary has been ill for three days.
I have lived here since 1998.
3. 现在完成时往往同表示不确定的过去时间状语连用,如already, yet, just, before, recently, lately等:
He has already obtained a scholarship.
I haven't seen much of him recently (lately).
We have seen that film before.
Have they found the missing child yet
4. 现在完成时常常与表示频度的时间状语连用,如often, sometimes, ever, never, twice, on several occasion等:
Have you ever been to Beijing
I have never heard Bunny say anything against her.
I have used this pen only three times. It is still good.
George has met that gentleman on several occasions.
5. 现在完成时还往往可以同包括现在时间在内的时间状语连用,如now, up to these few days/weeks/months/years, this morning/week/month/year, now, just, today, up to present, so far等:
Peter has written six papers so far.
Man has now learned to release energy from the nucleus of the atom.
There has bee too much rain in San Francisco this year.
The friendly relations and cooperation between our two countries have been enhanced in the past few years.
Up to the present everything has been successful.
6. 现在完成时表示现在之前业已完成的动作,虽然其效果或影响仍然存在但已不再继续,但是有一些现在完成时的句子,在后面加上for+一段时间,则现在完成时的动作就表示延续性.
Thomas has studied Russian. (现在不再学俄语)
Thomas has studied Russian for three years. (=Thomas began to study Russian three years ago, and is still studying it now.(同第2点用法第一个例句)
7. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作.
We have had four texts this semester.
===================
现在完成时的“完成用法”和“未完成用法”
1.现在完成时的"完成用法"
现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。
例如：He has turned off the light.他已把灯关了。(动作结束于过去，但说明的是现在的情况--灯现在不亮了。)
现在完成时"完成用法"的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语(如：already，yet，before，recently等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：this morning ／ month ／year...，today等)连用。
例如： Have you found your pen yet？你已找到你的钢笔了吗？
2.现在完成时的"未完成用法"
现在完成时的"未完成用法"指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。
例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。)
I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。)
此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far)等。
例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息。
注意：(1)现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。如：come，go，arrive，leave，join，become，die等。
(2)现在完成时常见两种句型：
①主语＋have / has been＋for短语
②It is＋一段时间＋ since从句
例如：He has been in the League for three years.或It is three years since he joined the League. 他入团已三年了
宾语从句，即：在主句中担当宾语的从句。学习宾语从句要抓住三要素：连接词、语序和时态。
连接词一般都是that(指事务或人),which（指事）,who（指人）
1．从句为陈述句，常选择连接词that或将that省略，直接与主句相连。
2．从句为一般疑问句，常选择连接词if或whether。在whether…ornot结构中不能用if替换。
3．从句为特殊疑问句，常选择what,when,where,which,who,how等的疑问代、副词作连接词。
注意：当who为主语时，句式为：who+谓语+其他三：判断时态情况：
1。主句是一般现在时，从句为各种时态情况
2。主句是一般过去时，从句为各种相应过去时态注意：从句描绘客观事实，用一般现在时。
宾语从句与中考试题
学习宾语从句并不难，只要你能过好下面的三道关：
第一关，选好连接词（也有人叫关联词）。
引导宾语从句的连接词，课本上写有三类，但从学习的角度看分为四类更为实用。
1．连词that：只起连接作用，在从句中不作句子成分，也无词汇意义，在口语中或非正式文体中常被省略。例如： 1）He knew（that）he should work hard．
2）I am glad（that）you've passed the exam．
2．连词whether或if：它们起连接作用，在从句中不作句子成分，作“是否”解，口语中多用if。例如： 3）Do you know whether he will ride here at 8 tomorrow morning？
4）Tom didn't know if／whether his grandpa liked the present．
作“是否”解的if和whether在具体用法上差别较大，同学们不易掌握。在宾语从句中用whether没有用if时受到那么多限制。例如：
5）He asked me whether or not I was coming．他问我是否要来。（该句中的whether不能换成if，因为if不能与or连用。）
3．连接代词who，whom ，whose，what， which：它们起连接作用，作句子成分，各有其自己的意义。例如：
6）The teacher asked the new student which class he was in？（武汉市）（which引导宾语从句，在从句中作定语，修饰class，意为“哪个”。）
7）Can you tell me whom he is waiting for？（天津市）
4．连接副词when，where， why，how：起连接作用，分别作时间、地点、原因、方式状语，各有其自己的意义。例如：
8）I wonder where he got so much money．对他从哪里弄到那么多钱我感到疑惑。（where在从句中作地点状语，修饰got，意为“哪里；什么地方”。）
9）He didn't tell me how old his friend was．（四川省）（how引导宾语从句，作程度状语，修饰old，意为“怎样；如何”等意。）
第二关，牢记宾语从句的语序是陈述句语序，即“连接词＋主语＋谓语＋其他”。这里特别强调的是，它的主语和谓语的语序是陈述句的语序，不是疑问句的倒装语序。例如： 10）You must remember what your teacher said．
11）—Dad，do you know when the football game will start？
—In half an hour．（宁波市）
12）汉译英：你能不能告诉我，我们去看望谁？
误：Can you tell me who（m）do we have to see？
正：Can you tell me who（m）we have to see？
错句的错误出在宾语从句中误用了疑问句的结构——主语前加了个助动词do。因为我们已经习惯了特殊疑问句，如W hat time does the plane arrive in Paris？就顺口说出“Do you know what time does the plane arrive in Paris？”这种错误句子来。但是一旦我们注意了，我们不久就习惯于说“Do you know what time the plane arrives in Paris？”了。
第三关，注意时态的呼应。 宾语从句中谓语动词的时态，常常受主句谓语时态的制约，这种现象称为“时态的呼应”。例如：
13）汉译英：我原以为你今天有空的。 误：I thought（that）you are free today．
正：I thought（that）you would be free today．
错句中宾语从句用are很可能是因为有 today，但因为主句谓语是thought，所以从句谓语就该用过去将来时would be了。
这种时态的呼应，如果主句谓语是现在时或将来时，宾语从句的谓语时态不受限制，如上述例句2），3），7），8），10），11），12）。如果主句时态是过去时，宾语从句一般要随着改为相应的过去时（即一般过去时、过去进行时、过去完成时、过去将来时等）。例如： 14）He thought he was working for the people．
15）I heard she had been to the Great W all．
16）John hoped that he would find a job soon．
但宾语从句如果表示定理法则、永恒真理等，则不变化：
17）The teacher told us that the earth moves around the sun．

E. 初二英语宾语从句讲解
在复合句中用作宾语的从句叫宾语从句。
1．语序
无论主句是陈述句还是疑问句，宾语从句都必须使用陈述语序，即“主句＋连词＋宾语从句（主语＋谓语＋……）”句式。根据连接词在从句中所担任的不同成分，可分为以下四种：
1）连接词＋谓语。连接词在从句中作主语。常见的连接词有： who，what，which等。如：
Could you tell me who knows the answer，please？你能告诉我谁知道答案吗？
The small children don't know what is in their stockings．这些小孩子不知道袜子里有什么东西？
2）连接词＋名词＋谓语。连接词在从句中作主语的定语。常见的连接词有：whose，what，which，how many，how much等。如：
He asked whose handwriting was the best in our class．他问我们班上谁的书法最好。
The teacher asked us how many people there were in the room．老师问我们房间里有多少人。
3）连接词＋主语＋谓语。连接词在从句中作宾语、状语或表语。常见的连接词有：who（m），what，which，how many，how much， when，why，how，where，if ／whether（在句中不充当任何成分）等。如：
He hasn't decided if he'll go on a trip to Wuxi．他还没决定是否去无锡旅行。
Could you tell me what I should do with the money ？你能告诉我我如何处理这笔钱吗？
4）连接词＋名词＋主语＋谓语。连接词在从句中作宾语或表语的定语。常见的连接词有：what，which，how many，how much，how等。如：
Do you know which class he is in ？你知道他在哪个班吗？
She asked me if I knew whose pen it was．她问我是否知道这是谁的钢笔。
2．连接词
1）当由陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：
He said that he could finish his work before supper．他说他会在晚饭前完成工作。
2）当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如：
I don't know if ／whether he still lives here after so many years．我不知道这么多年后他是否还住在这儿。
但在下列情况下只能用whether：
①在具有选择意义，又有or或or not时，尤其是直接与or not连用时，往往用whether（if…or not也可以使用）。如：
Let me know whether ／if he will come or not．（＝Let me know whether or not he will come）让我知道他是否能来。
I don't know whether ／if he does any washing or not．（＝I don't know whether or not he does any washing．）我不知道他洗不洗衣服。
I wonder whether we stay or whether wego．我不知道我们是去还是留。
②在介词之后用whether。如：
I'm interested in whether he likes English．我关心的是他是否喜欢英语。
We're thinking about whether we can finish the work on time．我们正在考虑是否能按时完成这项工作。
I worry about whether I hurt her feelings．我担心是否伤了她的感情。
③在不定式前用whether。如：
He hasn't decided whether to visit the old man．他尚未决定是否拜访那位老人。
I don't know whether to go．我不知去否。
He hasn't decided whether to go by bus or by train．他还未决定是乘公共汽车去还是坐火车去。
④whether置于句首时，不能换用if。如：
Whether this is true or not，I can't say．这是否真的我说不上来。
⑤引导主语从句和表语从句时宜用whether。如：
Whether she will come or not is still a question．她是否能来还是个问题。
The question is whether we can catch the bus．问题是我们能否赶上公共汽车。
⑥若用if会引起歧义时，则用whether。如：
Please let me know if you like the book．可理解为：
a．Please let me know whether you like the book．请告诉我你是否喜欢这本书。
b．If you like the book，please let me know．你如果喜欢这本书，请告诉我。
3）如果宾语从句原来是特殊疑问句，只需用原来的特殊疑问词引导。如：
Could you tell me why you were late for the meeting this morning？你能告诉我今天早上你为什么开会迟到吗？
3．时态
含宾语从句的复合句，主、从句谓语动词的时态呼应应包括以下三点内容：
1）如果主句的谓语动词是一般现在时，从句的谓语动词可根据需要，选用相应的任何时态。如：
I don't know when he will come back．我不知道他将何时回来。
He tells me that his sister came back yesterday．他告诉我他姐姐昨天回来了。
2）如果主句的谓语动词是过去时，宾语从句的谓语动词只可根据需要，选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。如：
①The children didn't know who he was．孩子们不知道他是谁。
②He asked his father how it happened．他问他父亲这件事是如何发生的。
3）如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等，不管主句用什么时态，从句时态都用一般现在时。如：
The teacher said that the earth goes round the sun．老师说地球绕着太阳转。
4．注意：
if和when既可以引导宾语从句，也可以引导状语从句，应注意它们在两种从句中的意思和用法的不同。if和when引导宾语从句时，分别意为“是否”和“何时”，其时态应和主句时态相呼应；它们引导状语从句时，意思分别为“如果，假如”和“当……时候”，当主句时态是一般将来时时，其时态用一般现在时。它们常常放在含有状语从句和宾语从句的题干中进行综合考查。如：
—Do you know when he will come back tomorrow ？你知道他明天什么时候回来吗？
—Sorry，I don't know．When he comes back，I'll tell you．对不起，不知道。当他回来了，我将告诉你。
—I don't know if he will come．我不知道他是否会来。
—He will come if it doesn't rain．如果不下雨，他会来的。
简化宾语从句常用六法
同学们常会遇到把含有宾语从句的复合句转化为简单句，使其与原句意思相同（或相近）的试题。下面就介绍几种常用的简化宾语从句的方法：
方法一：当主句谓语动词是hope， decide， wish， choose， agree， promise等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。例如：
Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.
We decided that we would help him. →We decided to help him.
方法二：当主句谓语动词是know， learn， remember， forget， tell等动词，且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：
She has forgotten how she can open the window. →She has forgotten how to open the window.
注：当主句谓语动词是tell， ask， show， teach等动词，且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：
Could you tell me how I can get to the station？ →Could you tell me how to get to the station？
方法三：当主句的谓语动词是order（命令），require（需要）等时，如果主句和从句的主语不一致，宾语从句可简化为“名词（代词）+不定式”结构。例如：
The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.
方法四：某些动词后的宾语从句，可以用介词加动名词（短语）等其他形式简化。例如：
He insisted that he should go with us. →He insisted on going with us.
The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.
方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式（作宾语补足语）”结构。例如：
Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground.
方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如：
It seemed that the boys were going to win. →The boys seemed to win.
除上述方法外，还有一些特殊句式的转化。例如：
I found that it was difficult to learn English well. →I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow.
They found that the box was very heavy. →They found the box very heavy

H. 初中英语宾语从句练习附讲解
在复合句中用作宾语的从句叫宾语从句。
1．语序
无论主句是陈述句还是疑问句，宾语从句都必须使用陈述语序，即“主句＋连词＋宾语从句（主语＋谓语＋……）”句式。根据连接词在从句中所担任的不同成分，可分为以下四种：
1）连接词＋谓语。连接词在从句中作主语。常见的连接词有： who，what，which等。如：
Could you tell me who knows the answer，please？你能告诉我谁知道答案吗？
The small children don't know what is in their stockings．这些小孩子不知道袜子里有什么东西？
2）连接词＋名词＋谓语。连接词在从句中作主语的定语。常见的连接词有：whose，what，which，how many，how much等。如：
He asked whose handwriting was the best in our class．他问我们班上谁的书法最好。
The teacher asked us how many people there were in the room．老师问我们房间里有多少人。
3）连接词＋主语＋谓语。连接词在从句中作宾语、状语或表语。常见的连接词有：who（m），what，which，how many，how much， when，why，how，where，if ／whether（在句中不充当任何成分）等。如：
He hasn't decided if he'll go on a trip to Wuxi．他还没决定是否去无锡旅行。
Could you tell me what I should do with the money ？你能告诉我我如何处理这笔钱吗？
4）连接词＋名词＋主语＋谓语。连接词在从句中作宾语或表语的定语。常见的连接词有：what，which，how many，how much，how等。如：
Do you know which class he is in ？你知道他在哪个班吗？
She asked me if I knew whose pen it was．她问我是否知道这是谁的钢笔。
2．连接词
1）当由陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：
He said that he could finish his work before supper．他说他会在晚饭前完成工作。
2）当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如：
I don't know if ／whether he still lives here after so many years．我不知道这么多年后他是否还住在这儿。
但在下列情况下只能用whether：
①在具有选择意义，又有or或or not时，尤其是直接与or not连用时，往往用whether（if…or not也可以使用）。如：
Let me know whether ／if he will come or not．（＝Let me know whether or not he will come）让我知道他是否能来。
I don't know whether ／if he does any washing or not．（＝I don't know whether or not he does any washing．）我不知道他洗不洗衣服。
I wonder whether we stay or whether wego．我不知道我们是去还是留。
②在介词之后用whether。如：
I'm interested in whether he likes English．我关心的是他是否喜欢英语。
We're thinking about whether we can finish the work on time．我们正在考虑是否能按时完成这项工作。
I worry about whether I hurt her feelings．我担心是否伤了她的感情。
③在不定式前用whether。如：
He hasn't decided whether to visit the old man．他尚未决定是否拜访那位老人。
I don't know whether to go．我不知去否。
He hasn't decided whether to go by bus or by train．他还未决定是乘公共汽车去还是坐火车去。
④whether置于句首时，不能换用if。如：
Whether this is true or not，I can't say．这是否真的我说不上来。
⑤引导主语从句和表语从句时宜用whether。如：
Whether she will come or not is still a question．她是否能来还是个问题。
The question is whether we can catch the bus．问题是我们能否赶上公共汽车。
⑥若用if会引起歧义时，则用whether。如：
Please let me know if you like the book．可理解为：
a．Please let me know whether you like the book．请告诉我你是否喜欢这本书。
b．If you like the book，please let me know．你如果喜欢这本书，请告诉我。
3）如果宾语从句原来是特殊疑问句，只需用原来的特殊疑问词引导。如：
Could you tell me why you were late for the meeting this morning？你能告诉我今天早上你为什么开会迟到吗？
3．时态
含宾语从句的复合句，主、从句谓语动词的时态呼应应包括以下三点内容：
1）如果主句的谓语动词是一般现在时，从句的谓语动词可根据需要，选用相应的任何时态。如：
I don't know when he will come back．我不知道他将何时回来。
He tells me that his sister came back yesterday．他告诉我他姐姐昨天回来了。
2）如果主句的谓语动词是过去时，宾语从句的谓语动词只可根据需要，选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。如：
①The children didn't know who he was．孩子们不知道他是谁。
②He asked his father how it happened．他问他父亲这件事是如何发生的。
3）如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等，不管主句用什么时态，从句时态都用一般现在时。如：
The teacher said that the earth goes round the sun．老师说地球绕着太阳转。
4．注意：
if和when既可以引导宾语从句，也可以引导状语从句，应注意它们在两种从句中的意思和用法的不同。if和when引导宾语从句时，分别意为“是否”和“何时”，其时态应和主句时态相呼应；它们引导状语从句时，意思分别为“如果，假如”和“当……时候”，当主句时态是一般将来时时，其时态用一般现在时。它们常常放在含有状语从句和宾语从句的题干中进行综合考查。如：
—Do you know when he will come back tomorrow ？你知道他明天什么时候回来吗？
—Sorry，I don't know．When he comes back，I'll tell you．对不起，不知道。当他回来了，我将告诉你。
—I don't know if he will come．我不知道他是否会来。
—He will come if it doesn't rain．如果不下雨，他会来的。
简化宾语从句常用六法
同学们常会遇到把含有宾语从句的复合句转化为简单句，使其与原句意思相同（或相近）的试题。下面就介绍几种常用的简化宾语从句的方法：
方法一：当主句谓语动词是hope， decide， wish， choose， agree， promise等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。例如：
Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.
We decided that we would help him. →We decided to help him.
方法二：当主句谓语动词是know， learn， remember， forget， tell等动词，且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：
She has forgotten how she can open the window. →She has forgotten how to open the window.
注：当主句谓语动词是tell， ask， show， teach等动词，且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：
Could you tell me how I can get to the station？ →Could you tell me how to get to the station？
方法三：当主句的谓语动词是order（命令），require（需要）等时，如果主句和从句的主语不一致，宾语从句可简化为“名词（代词）+不定式”结构。例如：
The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.
方法四：某些动词后的宾语从句，可以用介词加动名词（短语）等其他形式简化。例如：
He insisted that he should go with us. →He insisted on going with us.
The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.
方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式（作宾语补足语）”结构。例如：
Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground.
方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如：
It seemed that the boys were going to win. →The boys seemed to win.
除上述方法外，还有一些特殊句式的转化。例如：
I found that it was difficult to learn English well. →I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow.
They found that the box was very heavy. →They found the box very heavy
