⑴ 初中英语必学的句式，如宾语从句等。
宾语从句
1、that引导的宾语从句
当谓语动词表示肯定的概念时，如“希望”、“相信”、“知道”、“说”，其后面的句子一般用that引导。that 没有任何词汇意义，只具有语法功能，使读者清楚后面的句子是前面动词的宾语，除此之外，由于从句中有自己的主语，很容易与前面的主语分开，因此多数情况下that可以省略。如：
Betty thinks (that) trees improve the air. 贝蒂人为树可以改善空气。
I hope (that) it will snow this winter. 我希望今天冬天能下雪。
I believe (that) we will become good friends 我相信我们将会成为好朋友。
注：接that引导的从句的谓语动词不可以含疑问的含义。
2、whether/if 引导的宾语从句
如果我们要表示一个不确定的概念，比如“不知道”、“问”、“想知道”等等，就要用whether/if表示。从句用来whether/if连用，不能再用that。比如：
He doesn’t know whether they will plant trees on Saturday or not.
他不知道他们周六是否会去植树。
I can't remember whether/if I have seen him before 我记不清以前是否看过他。
He asks whether/if we will go fishing on Sunday 他问周日我们是否会去钓鱼。
Tom wants to know whether/if he needs to come early tomorrow.
汤姆想知道明天他是否有必要早来。
whether 和if 一般情况下没什么区别，但是从句后面有 or not 的话，一般就选用whether 构成whether….or not的结构。
3、疑问词引导的宾语从句
疑问词引导的宾语从句中，一定要用陈述句的语序。
He asks how we can help protect the environment.
问我们怎样才能为保护环境出点力
I can't understand why they like computer games so much.
我不理解他们为什么会如此喜欢电脑游戏。
Do you know when we will hold the sports meeting?
你知道我们什么时候开运动会吗？
这里补充一下：特殊疑问句有两种语序：
（1）．如疑问词作主语或主语的定语，即对主语或主语的定语提问，其语序是陈述句的语序：疑问词（主语）＋谓语动词＋其他成分
who is singing in the room？
whose bike is broken？
（2）．如疑问词作其他成分，即对其他成分提问，其语序是：疑问词＋一般疑问句语序？ 如：
what class are you in？
if引导的条件状语从句
① 主句为一般将来时态，if从句用一般现在时态（即主将从现）。
We will stay at home if it rains tomorrow.
如果明天下雨，我将要呆在家。
② 主句中含有情态动词，if从句用一般现在时态。
If you finish your homework, you can go home now.
如果你做完了作业，你现在可以回家了。
③ 主句为祈使句，if从句用一般现在时态。
Don’t jump into the river if you feel very hot.
如果你感到很热，不要跳入河里。
注：请认真看我的回答，相信我，没错的
⑵ 求初中英语的语法知识 （如宾语从句…）
一、定义：宾语从句就是在复合句中用作宾语句子。
二、例子：He told me that （专he lived in Moscow）.
这个句子中属“he lived in Moscow” 在整个句子中做宾语，因此叫宾语从句。
三、用法：
（一）要有连词：
1. 陈述句用 that .例：He said （that）he liked English。 （that 可省略）
2. 一般疑问句用 if 或whether：例：He asked （if）there was a man in the room。
3. 特殊疑问句用特殊疑问词：例：He wondered (where) Tom had gone.
(二）注意点：
1. 连词：
2. 时态：
3. 语序：
⑶ 求初中英语中宾语从句的用法
一、宾语从句的抄定义：宾语从句袭顾名思义就是在复合句中用作宾语的从句叫做宾语从句。即作及物动词、介词或某些形容词宾语的部分是由句子来充当。二、引导宾语从句的引导词分为三类即:
1．表示陈述语气用that
，作从句的原句是陈述句。
注意1:
引导宾语从句的that
常可以省略,但下列情况下不能省略。（1）and连接两个或两个以上的宾语从句，除第一个从句中的that以外,后面从句中的that不能省略。如：Everybody
could
see
what
happened
and
that
Tom
was
frightened.
（2）that引导的宾语从句作介词宾语时，that不能省略。
⑷ 初三英语 宾语从句
The teacher asked Simon if/ whether his sister got up early.
The boy said (that) he needed some English magazines.
宾语来从句时态一致就是说从句的时源态要和主句保持基本一致。比如这两个例句里主句都用了一般过去时，所以在改写从句时也应由原先的一般现在时改成一般过去时。
若把这两个题目改写下，改成: The teacher asks Simon, "Does your sister get up early?"那么相应的宾语从句也应改成：The teacher asks Simon if/ whether his sister gets up early.第二个例句也同理。
此外请注意人称也要相应改变哦。
⑸ 初三英语：宾语从句中引导词的用法
在复合句中作主句的宾语，引导词有：
连词：that (that 常可省略),whether, if
代词：who, whose, what ,which
副词：when ,where, how, why 等。
（一）that引导的宾语从句（在非正式场合that可以省略）
可跟that从句做宾语的动词有：
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句：The boy believes that he will travel through space to other planets.
注意事项：当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。
例句：I don’t think it is right for him to treat you like that.
在以下情况中that不能省略
1.当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。
例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.
2.当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。
例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
3.当that从句是双宾语中的直接宾语时，that不可省。
例句：I can’t tell him that his mother died.
注意事项：许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。
例句：I find it necessary that we should do the homework on time.
（二）由whether,if 引导的宾语从句
由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。
例句：I wonder whether(if) they will come to our party.
只能用whether，不能用if引导的宾语从句
1.在带to的不定式前
例句：We decided whether to walk there.
2.在介词的后面
例句：I’m thinking of whether we should go to see the film.
3.在动词后面的宾语从句时
例句：We discussed whether we had a sports meeting next week
4.直接与or not连用时
例句：I can’t say whether or not thet can come on time.
只能用if不能用whether引导的宾语从句
1.if引导条件状语从句，意为“如果”
例句：The students will go on a picnic if it is sunny.
2.if引导否定概念的宾语从句时
例句：He asked if I didn’t come to school yesterday.
3.引导状语从句even if（即使）和as if（好象）时
例句：He talks as if he has known all about it.
（三）连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
英语中的连接代词有：who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。
例句：Can you tell me whom you are waiting for?
英语中的连接副词有：when,where,why,how，在句中担任状语的成分。
例句：None of us knows where these new parts can be bought.

⑺ 初三中的英语宾语从句
P.c:这是我在网页上搜的，你看看吧。The Attributive Clause (定语从句)
I.在复合句中修饰名词或代词的从句叫做定语从句。被定语从句修饰的名词或代词叫做先行词。定语从句必须放在先行词之后。定语从句需由关系代词或关系副词引导。
II.引导定语从句的关系代词：who, whom, whose, which, that
关系副词：when, where, why
III. 关系代词和关系副词的作用：
（1）：桥梁作用：把先行词和定语从句联系起来。
（2）：代替先行词在定语从句中充当句子成分。
*关系代词在定语从句中可以做主语、宾语、定语。
*关系副词在定语从句中可以做状语。
IV.关系代词和关系副词的用法：
1. who指人，在定语从句中做主语。
The boy who is playing football is my son.
I do not like the students who often watch TV.
2. whom指人，在定语从句中做宾语。
The woman whom you met at the gate is my wife.
Pan Changjiang is an actor whom many girls love crazily.
3. whose指人或物，在定语从句中做定语
The boy whose mother is a doctor often falls ill.

4. which指物，在定语从句中做主语、宾语。
A plane is a machine which can fly in the sky.
A flying cock is a cock which is flying now.

5. that 多指人，有时也指物，在定语从句中做主语、宾语。
Examples of No. 1, 2, 4 & 5 can all be replaced by THAT clauses.
In the following conditions, we must be careful with the use of “that”.
Which, whom 在定语从句中做介词宾语， 这样的介词可以放在whom, which 之前， 也可以放在从句的原来的位置上。但是当介词被放在定语从句之前时， 则只能用whom, which. 不能用that.
Tom is the man from whom I learnt the news.
This is the house in which Lu Xun once lived.
Here is the question about which we have had so much discussion.
6. that 和 whom/that 的区别：在下列情况下必须用that:
(1). 先行词为all, little, much, everything, nothing, something, anything；everyone, no one, someone, anyone; everybody, nobody, somebody, anybody时。
Anyone that listen to him is a fool.
Is there anything that I can do for you?
Everything that we saw was of great interest to us.
(2). 先行词被all, every, very, no, some, any, little, much, only修饰时。

Rose is the only flower that I really like.
(3). 先行词被序数词修饰时。

(5).当有两个或两个以上的先行词后（既有人又有物）。

当先行词被the same, such修饰时, 关系代词往往用as。

7. when指时间，在定语从句作时间状语。

比较：

The days that/which we spent together made me happy.
V. 限定性定语从句和非限定性定语从句。
**限定性定语从句是句中不可缺少的组成部分，如果没有定语从句， 先行词的意思就不明确， 主句也不完整，从句和主句一般不用逗号隔开。
** 非限定性定语从句是主句先行词的补充说明，没有定语从句并不影响主句意思的明确或完整。这种定语从句一般用逗号与主句分开。在非限定性定语从句中通常不用关系代词“that”.
Last week Tom went to the beach, where he met Li Li 5 years ago.
Yesterday I bought a T-shirt, which only cost me 18 yuan.
