Question

he says that I am a boy还是he says that he is a boy？

Answer 1

第一句是直接引语，He said that “I am a boy”.第二句是间接引语。He said that he is a boy.

Answer 2

是后者，这是简接转述，所以人称代词应该变成he。He says that he is a boy..

Answer 3

加上标点就都一样了，
He says that:"I am a boy "
He says that he is a boy.

Answer 4

应该是后者，人称应该一致，他说他是个男孩。

Answer 5

He says that he is a boy.

他说他是一个男孩。

注意人称的改变
