导读：
如：She knew that the teacher had seen the film.
她晓得这位先生看过这部影戏。
（“that the teacher had seen the film”做 knew 的宾语，个中the teacher做主语，had seen做谓语，有主有谓是一个句子，由一个句子做宾语，所以它叫做宾语从句。）
二. 宾语从句的分类
1. 动词宾语从句：望文生义，它是位于动词背面的宾语从句。
比方：He asked whose handwriting was the best in our class．他问我们班上谁的书法最好。
2. 介词宾语从句：望文生义，它是位于介词背面的宾语从句。
比方：I agree with what you said just now.我赞同你适才说的话。
3. 形容词宾语从句：望文生义，它是位于形容词背面的宾语从句。
比方：I am afraid that I will be late. 生怕我要晚到了。
三. 指导名词性从句的衔接词
1. that:没有寄义，在宾语从句中不做身分。
that 在大多数情况下能够省略，但在以下几种情况下不能够省略：
①动词后接多于两个由that指导的宾语从句时，第一个that可省，但背面的that不可省。
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平常不可省。
Just then I noticed, for the first time, that he prepared to talk to us.
③当that从句是双宾语中的直接宾语时，that不可省
I can’t tell him that his mother died.
④ 当that置于句首时
That our team will win，I believe.
2.whether/if:示意是不是，在宾语从句中不做身分。
I don't know if /whether he still lives here after so many years. 我不晓得这么多年后，他是不是还住在这里。
3.衔接代词：what, which, who, whom, whose, whatever（在宾语从句中做主、宾、表和定语）
Do you know who has won Red Alert game？
你晓得是谁赢得了红色警戒的游戏么？
The book will show you what the best CEOs should know.
这本书会通知你最好的实行总裁该相识什么.
Do whatever you like.
你喜好做什么就做什么。
4. 衔接副词：where, when, how, why（在宾语从句中做状语）
这些小孩子不晓得什么在他们的长筒袜里。
Could you tell me why you were late for the meeting this morning？（why 在宾语从句中做缘由状语）
你能通知我为何你本日早上开会晚到吗？
He didn’t tell me when we should meet again.
他没有通知我什么时刻我们能再见面.
Could you please tell me how you use the new panel？
你能通知我怎样用这个新的操纵盘吗？
None of us knows where these new parts can be bought.
没有人晓得这些的新的零件能在那里买到.
四. 在做宾语从句的问题时应注重以下几点：
1. 时态
①当主句是如今时态时，宾语从句能够根据需要应用任什么时刻态。
I don't know when he will come back．我不晓得他将什么时刻返来。
He tells me that his sister came back yesterday．他通知我他姐姐昨天返来了。
②当主句是过去时态时，宾语从句必需是一种过去的时态。
She asked me if I knew whose pen it was．她问我是不是晓得这是谁的钢笔。
He said that he could finish his work before supper．他说他会在晚饭前完成事情。
③当示意客观事实或普遍真理的句子做宾语从句时，任什么时刻候都用平常如今时。
The teacher said that the earth goes round the sun．先生说过地球绕着太阳转。
2. 语序
任何从句都应用陈述句语序，宾语从句固然也不破例。
I want to know what he has told you. 我想晓得他通知了你什么。
3.虚拟语气
在demand、order、suggest、decide、insist, desire, request, command, doubt等示意请求、敕令、发起、决议等意义的动词后，宾语从句经常使用“（should） 动词真相”。
I insist that she (should) do her work alone. 我对峙要她自己事情。
The commander ordered that troops (should) set off at once. 司令员敕令军队立时动身。
4. 可应用it做情势宾语。
①动词make, find ,think,feel,consider,believe等背面有宾语补足语的时刻，则需要用it做情势宾语，而将that宾语从句后置，构造：S. vt it adj./n.(宾语补足语) o（宾语）。
I think it necessary that we take plenty of hot water every day.我以为天天多喝开水是有必要的。
I feel it a pity that I haven't been to theget-together.我没去会餐，觉得异常遗憾。
②有些动词带宾语从句时需要在宾语与从句前加it，这类动词主假如：hate,take,owe,have,see to
I hate it when they talk with their mouths full of food.我憎恶他们满嘴食品时措辞。
We take it that you will agree with us.我们以为你会赞同我们的。
He will have it that our plan is really pratical.他以为我们的设计确切可行。
5. whether与if 在作“是不是”的意义讲时在以下情况下平常只能用whether，不必if：
①指导介词宾语时,只能用whether；
His father is worried about whether he lose his work.他的父亲忧郁他是不是会落空事情。
I am thinking about whether I should quit my present job.我正在斟酌我是不是应当辞去现 在的事情。
Everything depends on whether we have enough money.统统要看我们是不是有充足的钱。
②宾语从句放在句首示意强调时，只能用whether；
Whether this is true or not, I really don't know.这是不是实在，我也不晓得。
③if与whether都能够与or not连用，但背面紧跟着or not时只能用whether；
We didn't know whether or not she was ready.我们不晓得她是不是预备好了。（此时只能用whether）
I wonder whether/if the news is true or not.我想晓得这个音讯是不是属实。（此时则两者都能够用）
④用if会引起歧义时，只用whether；
Could you tell me if you know the answer ?
这句话有两种意义：“你能通知我是不是晓得答案吗？”或“假如你晓得答案，请通知我，好吗？”。如用whether可防止歧义.
6. 关于whatever和no matter what
whatevet即能够指导宾语从句也能够指导妥协状语从句，指导妥协状语从句时能够换成no matter what。
They eat whatever they can find. 他们找到什么就吃什么。（宾语从句）
You can take whatever you like.你喜好什么就拿什么吧。（宾语从句）
Whatever difficulties we meet, we can work them out.不论碰到什么难题，我们都能处理它们。（妥协状语从句=no matter what）
Don’t lose heart whatever difficulties you meet. 不论碰到什么难题都不要泄气。（妥协状语从句=no matter what）
