中考英语语法考点总结——宾语从句（共16张PPT）

(共16张PPT)
宾语从句
宾语从句是一种名词性从句，在句中作及物动词的宾语，介词的宾语，或形容词的宾语。
考点1：连接词that的用法
that引导宾语从句用以陈述一个事实，that只有语法作用，没有实在在的意义，可以省略。
He said (that) he wanted to stay at home.
She doesn’t know (that) she is seriously ill.
I am sure (that) he will succeed.
考点2：连接词whether/if的用法
由if或whether引导的宾语从句，表示“是否”，二者通常可以互换。
Lily asked if/whether she liked it.
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
下列几种情况下通常使用whether：
（1）在具有选择意义又有or或or not时，尤其是直接与or not连用时，往往用whether。
（2）在介词之后用whether。
（3）在不定式前用whether。
Can you tell me whether the train has left or not
I don't know whether to accept or refuse.
I am not interested in whether you like the plan or not.
考点3：连接代词和连接副词的用法
由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。
Do you know who (whom) they are waiting for
He asked whose handwriting was the best.
Can you tell me where the No.3 bus stop is
考点1：陈述句语序
在含有宾语从句的复合句中，不管主句是陈述句还是疑问句，从句一律是用“连接词＋陈述句语序”，其标点符号由主句来决定。
There is not much difference between the two. I really don’t know _____.
A. what should I choose
B. which I should choose
C. which should I choose
D. what I should choose
考点1：主句为现在时或将来时
若主句为一般现在时或一般将来时，则从句的时态不限可视句子意义使用所需要的任何时态。
We all know chickens can't swim.
Don't you think Jim is speaking too quickly.
考点2：主句为过去时
若主句是一般过去时，从句必须用过去时态中的某一种。
I knew she had swept the floor already.
He asked if I was doing my homework this time yesterday.
若从句叙述的是客观真理、自然现象或永恒不变的规律时，则不受主句时态的限制，仍用一般现在时。
Our teacher told us light travels much faster than sound.
They knew the sun is much bigger than the earth then.
宾语从句在一定条件下，可以简化为“特殊疑问词+不定式”或“it +形容词+不定式短语”。
I’ve no idea what we’re going to do next.
= I’ve no idea what to do next.
Could you tell me how I can get to the post office
= Could you tell me how to get to the post office
I think it is difficult to solve the problem.
=I think it difficult to solve the problem.
