同学你好，该知识点来自沪江网校《英语零基础直达PETS三级/公共英语三级【10月班】》的课程，想要更系统的学习，欢迎进入课程学习。不仅可以和更多的同学一起学习，而且还有老师、助教随时的学习指导和知识点解答哦。

同学好，
这里是客观事实哦，太阳已经升起，所以不做变化哟。
还有其他不做变化的情况，比如
1）当主句的谓语动词是一般现在时的时候,如：
He always says, “I am tired out.”
He always says that he is tired out.
2）当主句的谓语动词是将来时的时候,如：
He will say, “I'll try my best to help you.”
He will say that he will try his best to help me.
3）当直接引语部分带有具体的过去时间状语时,如：
He said, “I went to college in 1994.”
He told us that he went to college in 1994.
4）当直接引语中有以when, while引导的从句,表示过去的时间时,如：
He said,“When I was a child, I usually played football after school.”
He said that when he was a child, he usually played football after school.
希望有用。
