当宾语从句是特殊疑问句时，

3. Sometimes we forget when we should stop.
4. I do not understand why they are so strict with me.

特殊疑问词

whose 谁的
what 什么
which 哪个，哪些
when 什么时候
where 在哪里

连接代词和连接副词有具体含义，在从句中充当成分，不可省略。
宾语从句连接词
连接代词
连接副词
连接词在宾语从句中充当成分
Do you know who is singing in the classroom
Could you tell me whom you spoke to just now
I wonder whose hat this is.
Do you know when he was born
在宾语从句中作主语
在宾语从句中作宾语
在宾语从句中作定语
在宾语从句中作状语
连接代词who和whom都指人。
who为主格，在从句中作主语；whom为宾格，在从句中作宾语。whom在口语中很少使用，大多数情况下，我们可以用who代替whom。
主句为一般现在时，宾语从句根据语境选择所需要的时态。
1
I know when she will come tomorrow.
我知道她明天什么时候来。
2
主句为一般过去时，宾语从句也要用过去的某种时态。
宾语从句的时态
She knew when Tom would come tomorrow.
她知道汤姆明天什么时候来。
She knew where Tom had gone.
她知道汤姆去哪了。
若宾语从句表示的是客观事实、普遍真理、自然现象或谚语等，无论主句是什么时态，从句都要用一般现在时。
3
He said that light travels faster than sound.
他说光比声音传播得快得多。
宾语从句的时态
The teacher said two and two makes four.
老师说二加二等于四。
I want to know how I get there.
I want to know how to get there.
宾语从句有时可转化为wh- + to do
