宾语从句
在句子中起宾语作用的从句叫做宾语从句.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.
1.宾语从句的连接词
从属连词
连接宾语从句的从属连词主要有that,if,whether.
that引导表示陈述句的宾语从句,而if和whether引导表示“是否”的宾语从句.

连接代词
连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等.
连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述.

2.动词的宾语从句

部分“动词+副词”结构也可以带宾语从句

动词短语也可以带宾语从句
常见的这些词有:

在上交试卷前确保没有任何错误.
可运用形式宾语it代替的宾语从句
①动词find,feel,consider,make,believe等后面有宾语补足语的时候,则需要用it做形式宾语而将that宾语从句后置.

我们都认为对这件事马上做出决定很重要.
②有些动词带宾语从句时寻要在宾语与从句前加it
这类动词主要有:hate, take , owe, have, see to.
I hate it when they with their mouths full of food.
我讨厌他们满嘴食物时说话.

他会认为我们的计划确实可行.

我们认为你会同意我们的.

③若宾语从句是wh-类,则不可用it代替

我们都认为你所说的是不可信的.

我们发现我们所学到的东西都是有用的.
3.介词的宾语从句
用wh-类的介词宾语从句

用that,if引导的介词宾语从句
有时候except,but,besides三个介词后可见到that引导的宾语从句

4.形容词的宾语从句
常用来引导宾语从句的形容词有: sure,certain,glad,please,happy,sorry,afraid,satisfied,surprised

5.if,wheter在宾语从句中的区别
①if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
②少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.
③whether后可以加or not,但是if不可以.
④在不定式前只能用whether.
⑤避免歧异时,我们常用whether而不用if.
6.哪些宾语从句不可以省略引导词that
当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;
当宾语从句较长时;
当主语状语置于主句尾,宾语从句之前时;
当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;
当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;
当宾语从句中的主语是this,that或this,that做主语的定语时;
当宾语从句是双宾语中的直接宾语时;
当宾语从句的主语是非谓语动词或主语从句时;
当主语中的谓语动词是固定词组时;
当宾语从句有it做其先行词时;
在直接引语中,转述分句把宾语从句隔开时.
7.宾语从句的否定转移
主句是谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式.
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课,是不是?
8.宾语从句的时态和语序
当主句为现在时或将来时的时候,宾语从句的时候一般不受主句的时态所影响.
当主句为过去时的时候
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
I only knew he was studying in a western country,but I didn’t know what country he was in.
我只知道他当时在西方的一个国家读书,可不知道是哪个国家.
He asked me if I was reading the story The Old Man and the Sea when he was in.
他问我他进来的时候我是否在读.
②从句过去完成时表示该动作发生在主句谓语动作之前
He told me that he had told Mary about the meeting already.
他告诉我他已经把有关会议的事情告诉的了Mary.
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
The reporter asked if the government would take necessary measures to put down the to-do.
记者问政府是否会采取必要的措施镇压骚乱.
如果从句是一个客观真理,那么从句的时候不根据主句的时态而变化
The teacher said that the moon goes around the earth yesterday.
老师昨天说月亮绕着地球转.
当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首
Who do you think the public might choose as their favorite singer this year?
你认为今年公众会选谁为他们最喜欢的歌手.

They believe that you can do it中，主句是They believe，从句是that you can do it。that是引导词，可以省略。

一. 句子翻译：

他们相信你能做到。

二. 句子成分分析：

They 主句主语

believe主句谓语

 that 引导宾语从句，不作任何成分

you 从句主语

can do从句谓语

 it从句宾语

三. 如何判断从句：

判断一个句子是什么从句，依据这个句子在整个句子里面作什么成分，

如果是作主语，就是主语从句，一般在句子开头，但是为了避免头重脚轻，会用形式主语it代替，而把主语从句放在句子后面；

如果是放在及物动词或者介词后面作宾语，表示内容关系的是宾语从句；

如果在be动词或者其它连系动词后面，就是表语从句；

如果在名词后面，限制修饰名词的就是定语从句；

名词后面，但是表示名词的内容就是同位语从句；

在句子里面作状语，表示时间、地点、原因、方式、条件等就是状语从句。

例如：

1、My idea is that we should do it right now.（表语从句）

我的想法是我们应该马上做这件事。

2、She won’t believe that he has become a thief.（宾语从句）

她不会相信他已经变成了一个小偷。  

3、That he is a famous singer is known to us.（主语从句）

我们都知道他是一位著名的歌手。

4、I knew the news that our team won the match. （同位语从句）

我知道我们队赢了比赛的消息。

5、His suggestion is that we should finish the work at once.（表语从句）

他的建议是我们应该立即完成这项工作。  

6、My grandfather lives in a village that is far away from here.（定语从句）

我祖父住在离这里很远的一个村子里。  

7、I couldn't remember the words that he said.（定语从句）

我记不起他说了什么。

8、I can lend you the book on condition that you return it in time.（状语从句）

如果你能及时归还，那我可以把书借给你。

They believe ...是主句，you can do it是从句。

这是一个宾语从句，从句的引导词that之前的部分是主句，that不充当成分，也无实际意义，that之后的句子称为从句。

• 分类:宾语从句分为三类:(1)动词的宾语从句,介词的宾语从句和形容词的宾语从句.

• 时态: 1·主句用一般现在时，从句可用任意时。 2·主句用过去时，从句用过去某个时态。 3.当为客观事实和科学真理时，从句为一般现在时。Do you know who has won this game?你知道谁赢了这一局游戏吗？Could you please tell me how you read the new panel? 你能展示给我怎么用这个新的操作盘吗?

• (2)宾语从句的从属连词主要有that,if,whether.that引导表示陈述句的宾语从句,而if和whether引导表示"是否"的宾语从句. He told me that he would go to the college the next year 他告诉我他将在下一年上大学. I don't know if there will be a bus any more. 我不知道是否还会有公交车. Nobody knew whether he could pass the exam. 没人知道他是否会通过考试.

• 连接代词主要有who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等.连接代词一般指疑问,但what, whatever除了指疑问外,也可以指陈述.I have found out that all the tickets for the concert have been sold out. 我发现这场音乐会的所有票都卖光了. Can you work out how much we will spend during the trip? 你能计算出这次旅行我们将花费多少钱吗? 
  

that之前they believe 是主句，that 之后you can do it 是从句。that 一般是主句从句的分界线。
