直接引语变间接引语问题这两句如何变为间接引语?1、He said :"I've been coming up here night and night for weeks now."2、He say:"I've been coming up here night and night for weeks now."

这里是方法：
一、
1、she said：“I am a student”& she said she was a student
2、she said：“I played football”& she said she had played football
3、she said：“I am going to the park”& she said she was going to the park
4、she said：“I am doing my homework”& she said she was doing her homework
5、she said：“I have had dinner”& she said she had had dinner
6、she said：“I can swim”& she said she could swim
7、he said：“is this your book”& he said if this was my book
8、he said：“how old are you”& he said how old I am
9、he said：“open the door”& he said to open the door
10、he said：“what a clever boy he is”& he said he is a clever boy
二、
一般现在——一般过去
一般过去——过去完成
一般将来——过去将来
现在完成——过去完成
现在进行——过去进行
过去完成——过去完成
can——could
will——would
may——might
若前面是say tell ask等等,变间接引语时时态不变；
若前面是said told asked等等,变间接引语时时态按以上规律变.
一个一个字打上去的,给点分吧!绝对正确!
有了我这个以后就不用怕出这类题了,全都是很厉害的老师讲的!
