國中英語必備知識1.賓語從句的語序問題
以上介紹了三種賓語從句，同學們一定要注意，在疑問詞或if/whether引導的賓語從句中，一定要用陳述句語序。

We don’t know where her office is.
My teacher wanted to know if I like English.
2.賓語從句的時態問題
一般情況下賓語從句的時態必須和主句的時態保持一致：
當主句的謂語動詞是一般現在時時，賓語從句中的謂語動詞不受時態限制。
says that she is a student.
She says that she was a student two years ago.
She says that she will be a college student soon.
She says that she has been a college student for 3 years.
當主句的謂語動詞是過去時時，賓語從句中只能用過去的某種時態。
told me that he would leave soon.
He said that he was watching TV.
He didn’t tell me whether he had finished this homework.
但如果賓語從句中講述的客觀事實、一般真理或自然現象時，則不受它限制。
