Question

将直接引语变成间接引语

The teacher said:"The earth goes round the sun."怎么变，讲解一下好吗？

最好顺便帮我讲一下一般过去时→过去完成时，最好举个例子

Answer 1

The teacher said that the earth goes round the sun."直接引语如果是客观真理、自然规律等变间接引语时时态不变

一般过去时→过去完成时和过去进行时,主要的是把谓动词变成过去完成时和过去进行时,再把相应的人称变化一下,当然还要特别注意时间状语的适当变化.
既然你问了我就给你把直接引语变间接引语的重要点打完吧!(是个表格,由于不能打横线,就将就着看吧)

直接引语 间接引语
一般现在时 一般过去时
现在进行时 过去进行时
现在完成时 过去完成时
一般过去时 过去完成时
过去完成时 过去完成时
一般将来时 过去将来时
注意：直接引语如果是客观真理、自然规律等变间接引语时时态不变
e.g.
1"I visited my teacher yesterday."he said
→ He said that he had visited his teacher the day before
2.He said to her,"What time did you go to bed last night?"
→He asked her what time she had gone to bed the night before.
3.He said to her,"What are you going to do this Sunday?"
→He asked her what she was going to do that Sunday.
4.He asked Xiaolan."Did you have breakfast this morning?"
→He asked xiaolan if she had had breakfast that morning.

Answer 2

The teacher said that the earth goes round the run.
因为地球绕着太阳转是客观事实,所以后面的从句仍然用一般现在式.如果从句不是客观事实,就将时态往后移.如:The man said:"I can do it."该成The man said that he could do it.

Answer 3

The teacher said that the earth goes round the sun. 此直接引语讲述的是客观事实，所以变间接引语时即使主句是过去时态，也不需要转换时态。
如果主句是过去时态，那么为一般过去时的直接引语转换为间接引语时需用过去完成时态。如：He said,"I gave Mary the book yesterday." 转换成：He said that he had given Mary the book the day before.

Answer 4

直接引语改为间接引语

Answer 5

这还不简单，把said后面的句子改成过去式就可以了（逗号去掉）
