① 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。
② 初一学到初三的英语语法有哪些
语法知识是在掌握一定量的单词和短语的基础上才能获得的。因此，单词的形态变化是语法学习的基础之基础。而九种基本时态和含有不复杂的状语从句及宾语从句的复合句是初中毕业班学生学习的重点也是语法学习的难点。总之，语法部分是英语学习的重点和难点。语法知识掌握得好，将大大加快英语学习的进程。本文归纳了词法、九种基本时态以及初中生需要掌握五种基本从句。希望对广大初三生们有所帮助。
一. 词法
1.名词
1.1 名词的可数与不可数
可数名词指表示的人或事物可以用数来计量，它有单数与复数两种形式。不可数名词指所表示的事物不能用数来计量。物质名词与抽象名词一般无法用数目，来统计，都成为不可数名词。
不可数名词前一般不能用冠词a、an来表示数量，没有复数形式。要表示“一个……”这一概念，就须加a piece of这一类短语。要注意许多名词在汉语里看来是可数名词，在英语里却不可数。如：chalk，paper，bread，rice，grass，news等。
1.2 名词复数的规则变化
A.一般情况下加-s。
B.以s, x, ch, sh, 结尾的加-es
C.以辅音字母加y结尾的改y为i再加-es
D.以f，fe结尾的，去掉f或fe，变成v再加-es
1.3 名词的所有格
A.单数名词词尾加’s，复数名词词尾若没有s，也要加’s。
如：the worker's bike，the Children’ s ball
B.表示几个人共有一样东西，只需在最后一个人的名字后加’ s若表示各自所有，则需在各个名字后’ s。
如： This is Lucy and Licy’ s room.
These are Kate's and jack’ s rooms.
C. 如果是通过在词尾加—s构成的复数形式的名词，只加’。
如:the students’ books，the girls’ blouses
(另外：名词+of+名词名词是有生命的，我们就用’s结构来表示所有关系。如果名词所表示的事物是无生命的，我们就要用名词+of+名词的结构来表示所有关系。)
2.代词：
人称代词，物主代词，反身代词，指示代词，不定代词
2.1 人称代词
第一人称单数
I me my mine myself
复数 we us our ours ourselves
第二人称
单数 you you your yours yourself
复数 you you your yours yourselves
第三人称
单数 he him his his himself
she her her hers herself
it it its its itself
复数 they them their theirs themselves
2.2 物主代词
物主代词的用法：
形容词性物主代词后面一定要跟上一个名词。
名词性物主代词可作主语、表语、宾语。
2.3 反身代词
反身代词的构成分两种：第一、二人称反身代词在形容词：性物主代词后加上self或selves，第三人称的反身代词在宾格代词后加上self或selves.
反身代词的用法：一种是作宾语，由主语发出的动作又回到动作者本身。
如：I enjoyed myself at the party.另一种是作名词或代词的同位语;用来加强语气。如：I
can do it myself.
2.4 指示代词
指示代词的特殊用法：
(1)为了避免重复，可用that，those代替前面提到过的名词，但是this，these不可以。
(2)this，that有时可代替句子或句子中的一部分。
2.5 不定代词
one,some,any,other,another,all,both,each,neither,many,much等

(sit) at table就餐; sit at the table坐在桌边
go to school去上学;go to the school去那所学校;in hospital住院;in the hospital在那个医院里
4.数词
4.1 数字的表示
三位数数词要在百位和十位(若无十位则和个位)之间加and。
1，000以上的数字，从后向前第三位数加一个“，”，第一个“，”前为thousand，第二个“，”前为million，第三个“，”前为billion。

(2)当形容词带有表示度量的词或词组作定语或表语时，定语或表语要后置。如：

The hole is about two metres deep.
5.2 形容词的比较等级
(1) 单音节词和少数双音节词，在词尾加—(e)r，—(e)st来构成比较级和最高级。其他双音节
词和多音节词，在前面加more，most来构成比较级和最高级。如：

5.3 副词比较级的构成
(1) 单音节副词和个别双音节副词通过加-er，-est来构成比较级和最高级。

三.基本从句
从句的共同特点
从句是指在一个句子中充当一个成分的句子，充当什么成分就叫什么从句，如：充当宾语就叫宾语从句，充当定语成分就叫定语从句。
从以上定义中我们可以得出关于从句的一个最大特点：从句是句子。
从句的共同特点：1.从句都有自己的连接词 2.从句都是陈述语序(陈述语序就是主语在前，谓语在后，如：He is a teacher主语 He 在谓语is之前，因此是陈述语序，而Is he a teacher? 主语 He 在谓语is之后，因此不是陈述语序。)
1.宾语从句
宾语从句是指在一个句子中充当宾语的句子，如：He said that he wanted to be a teacher when he grew up.
宾语从句的特点：
①宾语从句有自己的连接词
②宾语从句用陈述语序
③宾语从句的时态
①宾语从句的连接词：宾语从句的连接词包括that、if/whether(是否)、特殊疑问词。
②宾语从句的语序;
A.宾语从句的连接词后加陈述语序(主语在前，谓语在后),如：I want to know if he can come tomorrow
B.当连接词本身又是宾语从句的主语时，后面直接加谓语动词，如：She asked me who had helped him.
③宾语从句的时态，只要记住以下口诀就可以了“主现则从任，主过则从过，客观真理一般现”
A.主现则从任：主句如果是一般现在时，则从句根据时间状语需要从八种时态中任选一种，如：1.He tells me he likes English very much(一般现在时)
B.主过则从过：主句如果是一般过去时，则从句根据时间状语需要从四种带“过”字的时态中任选一种，带“过”字的时态分别是如：一般过去时，过去进行时，过去将来时，过去完成时。
如：He told me that he liked playing football(一般过去时)
C.客观真理一般现:客观真理永远用一般现在时。
如：1.He says the moon goes around the earth.
2.状语从句
2.1 时间状语从句：在一个句子中作时间状语的句子。
时间状语的连接词：when(当…时候) while(当…时候) as(当…时候) after(在…以后) before(在…以前) as soon as(一…就) since(自从…到现在) till /until(直到…
才) by the time(到…为止)依旧是连接词后加陈述语序。
举例：when当…的时候(一般情况下主句是将来时的时候，从句要用一般现在时。)
Mozart started writing music when he was four years old.
2.2 原因状语从句：在一个句子中作原因语的句子。
连接词：由连词because, since, as引导, 也可由for, now that 等词引导。
举例：I didn’t go to school yesterday because I was ill.
2.3 条件状语从句
连接词：if如果, unless (=if not) 除非。(让步)
举例：If it doesn’t rain tomorrow, we will go hiking.
2.4 目的、结果状语从句
目的状语从句是指在一个句子中充当目的状语的句子。
结果状语从句是指在一个句子中充当结果状语的句子
目的状语从句连接词so that, so…that , in order that 引导。
结果状语从句连接词 so…that, such…that, so much/many…that引导。
举例：so…that 如此…以至于
The scientist’s report was so instructive that we were all very excited.
2.5 让步状语从句
让步状语从句是指在句子中作让步的状语的句子
连接词： though, although.，whether…or not
举例：Although he is rich, yet he is not happy.
3.no matter从句
结构："no matter +特殊疑问词疑问词+陈述语序" 或"特殊疑问词+后缀ever+陈述语序"
如：No matter what happened, he would not mind.
注意：no matter 不能引导主语从句和宾语从句。
4.定语从句
定语是指在句子中用来修饰名词、代词的成分
如：I will give my teacher a bunch of beautiful flower.(中beautiful就是定语)
定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后
如：I have met the doctor who is in the No.1 hospital.
定语从句的连接词：
连接代词：who、which、whom、whose、that
连接副词：when、where、why
5.名词性从句
在句子中起名词作用的句子叫名词从句。名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词可分为三类：
连接词： that, whether ,if (不充当从句的任何成分)
连接代词：what, whatever, who, whoever, whom, whose, which
连接副词：when, where, how, why
如：That she was chosen made us very happy.
③ 初三英语宾语从句
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。

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

that
his

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

3.引导状语从句even
if（即使）和as
if（好象）时
例句：He

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.

⑧ 谁知道新版英语书九年级的宾语从句在第几单元
宾语从句是名词性从句的一种。在主从复合句中充当宾语，位于及物动词内、介词或复合谓语之容后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
宾语从句意义
语法是语言的组织规律，任何人在使用语言时，不管他是否学过语法，都须合乎语法。另外，总结语法本身的规律也能加深我们对语言的理解，让我们能够真正熟练地运用语言。（宾语：指一个动作（动词）的接受者，常置于动词之后，也有双宾语结构例句：he gave me a book，类似拥有me和book两个宾语的句子叫双宾语从句），在复合句中，由一个句子充当宾语，这个句子就叫做宾语从句。
⑨ 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.
