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.
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.
I think it necessary that we take plenty of hot water every day .
我认为每天多喝开水是有必要的.
I feel it a pity that I haven’t been to the get-together.
我没去聚会,感觉非常遗憾.
I have made it a rule that I keep diaries.
我每天写日记成了习惯.
We all find it important that we (should) make a quick decision about this mater.
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.
He will have it that our plan is really practical.
他会认为我们的计划确实可行.
I take it that you will agree with us.
我们认为你会同意我们的.
When you start the engine, you must see to it that car is in neutral.
开启发动机时, 一定要使汽车的离合器处于空挡位置.
③若宾语从句是wh-类,则不可用it代替
We all consider what you said to be unbelievable.
我们都认为你所说的是不可信的.
We discovered what we had learned to be valuable.
我们发现我们所学到的东西都是有用的.

宾语从句,一般来是这样:
1.时态倒移
2.一般可以用that引导
3.直接引语改为间接引语用宾语从句:
一:特殊疑问句改为陈述句语序
二:一般疑问句改时要加whether和if,表"是否"意
一般来说,学校里应该就教这个吧!
我也是初中生哦!比较了解吧!
主语从句与宾语从句同属名词性从句,二者有很多相似之处.我们已熟练掌握了宾语从句,因此了解二者的共性特征,掌握主语从句的难度将大大减轻.
(一)语序相同:都采用陈述语序.如:
I don't know whether he has come back.(宾从)
Whether he has come back is still unknown.(主从)(划线部分不可改为:Whether has he come back)
(二)从句与主句的时态搭配规则相同
1.主句用过去时,从句一般用过去时(如从句表示客观真理,可用现在时态).如:
I didn't know what food she bought.(宾从)
It was unknown what food she bought.(主从)
At that time people already knew that the earth is round.(宾从)
It was already known at that time that the earth is round.(主从)
2.主句为现在时,从句可根据需要选用各种时态.如:
I don't know when he came back/when he'll come back/whether he has come back.(宾从)
It is unknown when he came back / when he'll come back/whether he has come back.(主从)
(三)引导词相同,且在从句中的含义及句法功能相同
主语从句和宾语从句一样,引导词的选择都取决于该词在从句中的含义及充当的成分.各引导词功能如下:
(四)表示"建议"或"要求"时,从句都用虚拟语气.如:
They suggested that Tom (should) start as early as possible. (宾从)
It was suggested that Tom (should) start as early as possible. (主从)
二、查漏补缺,把握主语从句的独特性.
(一)注意主语从句与主句谓语动词的一致
1.主语从句多表示单一概念,因此主句谓语动词多用单数.如:
When and where we'll go isn't decided.
2.what引导的主语从句,根据表达含义的不同确定主句谓语动词的单复数.如:
What we need are books/is water.
(二)熟记"it作形式主语,主语从句后置"的常见句型结构
1.It + seem/appear/happen/chance等的适当形式+that从句.
2.It +系动词+过去分词+ that从句.
3.It +系动词+形容词+ that从句.
该句型中,如从句表示"应该做某事",从句需用虚拟语气.如:
It's necessary/important that you (should) be ready by 5 o'clock.
