直接引语和间接引语的相互转换
1.若直接引语为陈述句，则间接引语需改为由that所引导的宾语从句。如：
The man said,"I am hungry."
The man said that he was hungry.
2.若直接引语为祈使句，则间接引语需改为动词不定式，原动词say也要改为可以带动词不定式作宾语补足语的动词如tell, ask, order, advise等。如：
1)The teacher said,"Be careful with your spelling."
The teacher told us to be careful with our spelling.
2)"Don’t stick out your heads as the bus goes."said the driver.
The driver told us not to stick out our heads as the bus went.
