直接引语变间接引语时,若直接引语是一般现在时,那间接引语是什么时态?

一般分三种情况
主句中的谓语是一般现在时,引语部分的时态不变 e.g: She says ,"she is happy."----> She says she is happy.
主句中的谓语是一般过去时,引语部分的时态是一般过去时 e.g:She said ,"she is happy." ---->She said she was happy
引语如果陈述的客观事实或真理,永远用一般现在时. e.g:The teacher said," the moon goes around the earth." ---->The teacher said the moon goes around the earth.

根据主句中谓语的时态决定。主句谓语是一般现在时谓语不变，主句是过去时，引语的时态要推早一个时态
