eg.
Tell him which class you are in 。
Do you know what he likes?
注:
(1)主、從句時態一致:
主句謂語過去時,從句相應過去時;
He answered that he was listening to me.
主句謂語現在時,從句時態任所需;
eg. He says (that) he will leave a message on my desk.
They know (that) he is working hard.
具體過去永不變,真理格言現在時;
told me that he was born in 1980.
Father told me that practice makes perfect 。
(2)否定前移,及完成反意問句
在think / believe / suppose / guess / imagine / expect等動詞後跟賓語從句否定式時,應轉移到主句上去,完成反意問句時,應與從句主、謂保持一致。(注: 否定前移的條件是,主句主語是第一人稱)
eg. I don‘t think you are right ,are you ?
I don‘t believe they have finished their work yet,have they ?
(3)運用虛擬語氣的情況
在表示:
建議 suggest 、advise、propose;
要求demand 、desire、request;
決定 decide;
命令 order、command、require;
堅決主張 insist;
等動詞後跟賓語從句,用(should)+v.(虛擬語氣)
