賓語從句的時態(tài)
(1) 若主句是一般現(xiàn)在時、一般將來時或祈使句時，賓語從句根據(jù)句子的意義使用需要的時態(tài)。如：
We don’t know who has broken the window. But we will find out who has done that.
Please tell me where we will go.
(2) 若主句是一般過去時，賓語從句要用相應的某種過去時態(tài)，如一般過去時、過去進行時、過去將來時或過去完成時。如：
He said: I’m a student. ----- He said that he was a student.
The teacher asked: What is Mike doing? ----- The teacher asked what Mike was doing.
(3) 若賓語從句敘述的是客觀真理或永恒不變的規(guī)律，則應采用一般現(xiàn)在時，不受主句時態(tài)的限制。如： Our teacher said that the earth moves round the sun.
