________________________________I often doubt whether it is worth spending so much time on homework. I do not understand why they are so strict with me.学好宾语从句共有三关：
连接词——语序——时态
Are you ready?连接代词和连接副词引导宾语从句We use a question word to introduce an object clause that expresses a wh- question. The word order in the clause should be the same as that in a statement.
Tip:
Whom is an object pronoun. We can use who instead of whom.pron. 谁(宾格)1. I wonder what I should do.
2. Daniel does not know whom he should talk to.
3. Sometimes we forget when we should stop.
4. I do not understand why they are so strict with me.
5. I do not know how I should deal with the problem.连接词 连接代词和连接副词有词义，并且在句中
充当句子成分。
e.g. Can you tell us what they are doing?
what在从句中作宾语，意思是“什么”。
宾语从句的语序必须是陈述语序。
e.g. She wants to know why that little boy is
crying.
宾语从句中的连接代词who与whom都指
人，意思是“谁”。其中who为主格，在从句
中作主语；whom为宾格，在从句中作宾语。e.g. I do not know who is playing the piano
next door.
Can you guess whom/ who my father
is talking with?
注意：whom在口语中很少使用, 大多数情况下可以用who代替whom。
含有宾语从句的复合句的标点由主句决定。
e.g. I am not sure if/ whether the bag is big
enough.
Can you tell me which bus I should take?Summary宾语从句三要素：
连接词 that（陈述句）
if/whether（一般疑问句）
who; whom; whose; which; what
when; where; why; how(特殊疑问句)
时态 主句为一般现在时，
从句可以是任何时态
主句为一般过去时，
从句进行相应的变化
客观真理，自然现象等不变
