① 主句的谓语动词是一般过去时

如主句的谓语动词是一般过去时，直接引语变间接引语时，从句的谓语动词在时态方面要作相应的变化。直接引语改为间接引语时，动词时态相应变化如下：

He said,"I usually watch TV on Sunday."他说："我常在星期天看电视"。

→He said that he usually watched TV on Sunday.他说他常在星期天看电视。

He said,"I'm using the knife."他说："我正在用小刀。"

→He said that he was using the knife.他说他正在用小刀。

She said,"I have not heard from him since May."她说："自从五月份来我就没收到他的来信。"

→She said that she had not heard from him since May.她说自五月以来她就没收到他的来信。

He said,"I came to help you."他说："我来帮助你。"

→He said that he had come to help me.他说他来帮助我。

He said,"I had finished my homework before supper."他说："晚饭前我己做完了作业。"

He said,"We shall have finished the work by that time."他说："我们将在那时以前完成工作。"

→He said that they should have finished the work by that time.他说他们将在那时前完成工作。

注意：直接引语如果是客观真理、名人名言、与一个具体的过去时间连用说明客观事实时，变为间接引语时，时态不变。

The teacher said,"The earth is round."老师说："地球是圆的。"

→The teacher said that the earth is round.老师说地球是圆的。

He said,"I was born in Shangdong in 1965."他说："我1965年生于山东。"

→He said that he was born in Shangdong in 1965.他说他1965年生于山东。

He said,"Columbus discovered America in 1492."他说："哥伦布在1492年发现了美洲。"

→He said Columbus discovered America in1492.他说哥伦布在1492年发现了美洲。

② 主句的谓语动词是现在时或将来时如果主句的谓语动词是现在时或将来时，直接引语变为间接引语时，时态一律不变

He says,"I finished the work."他说："我做完工作了。"
