同学你好~
直接引语变为间接引语时，若主句为过去时态，变为间接引语的宾语从句通常要将时态往后退一个，即
一般现在时变为一般过去时，
一般将来时变为过去将来时，
现在进行时变为过去进行时，
现在完成时变为过去完成时，
一般过去时也变为过去完成时，等等(若直接引语为过去完成时，变为间接引语可以不变)。

另外，若直接引语中有情态动词can, may等，也应变成过去式could, might等 (情态动词must可以变为had to，也可不变，should, ought to, had better 等可以不变)。如：
“I like to watch TV,” she said. 她说：“我喜欢看电视。”→She said that she liked to watch TV. 她说她喜欢看电视。
He said, “I’m waiting for her.” 他说：“我在等她。”→He said that he was waiting for her. 他说他在等她。

“It will rain soon,” he said. 他说：“很快就会下雨。”→He said that it would rain soon. 他说很快就会下雨。

注意：(1) 若直接引语为客观真理，则变为间接引语时时态不变：

The teacher said, “The earth turns around the sun.” 老师说：“地球绕着太阳转。”→The teacher said that the earth turns around the sun. 老师说地球绕着太阳转。

(2) 有时由于直接引语有特定的过去时间状语，变为间接引语时时态也可不变：

He said, “I was born in 1954.” 他说：“我是1954年生的。”→He said that he was born in 1954. 他说他是1954年生的。

但是有时候要根据表达的具体习惯和意图来决定，比如
At the time the murder was committed, the man said he was travelling on the 8 o'clock train to London. 这时已经很明确是过去正在进行的动作了，而完成进行时强调一直到过去某个时间还在继续，可以不用特别强调这个，比如
Jack said. John, where were you going when I met you in the street?
→Jack asked John where he was going when he met him in the street.

The inspector asked if he always caught such an early train.
这只是这个人的一种过去的习惯行为，所以用一般过去时就可以了。

The inspector asked him what time he arrived at the station.
这里用had arrived也是可以的。

祝同学学习进步~
