"My son is a good boy,"Mrs.Green said to me.(合并为一句)

题目

"My son is a good boy,"Mrs.Green said to me.(合并为一句)
Mrs.Green ___ me that _____ son ___ a good boy.
told:his:is 第三个为什么是is 不是要前后时态要一致的吗?

答案

Mrs.Green told me that his son is a good boy.
told me发生在过去,但是分句如果阐述的是一个事实便应该用一般现在时.
his son is a good boy这是一个事实,所以应该不受主句一般过去时的影响而使用is.
