你是说直接引语改为间接引语的,时态吧
1.宾语从句的主语：一随主,二随宾,三不变.
e.g.(1)She said "I will go home ."
改：She said that she would go home.（一随主）
(2)She said to me "You can go with me.".
改She said to me that I could go with her.(二不变)
(3) She said to me "He will go home."
改She said to me that he would go home.(三不变)
2.宾语从句中注意时态
1.若主语为一般过去时,则宾语从句的时态要变为过去的某一时态.
e.g.(1)He said "I wil go home.“
改 He said that he would go home.(一般将来时改为过去将来时)
（2）He said "I have had lunch."
改 He said that he had had lunch.(现在完成时改为过去完成时)
(3)He said "I know a lot about the teacher."
改He said that he knew a lot about the teacher.(一般现在时改为一般过去时)
（4）He said "I had lunch."
He said that he had had lunch.(一般过去时改为过去完成时）
(5)He said "I am playing games"
改He said that he was playing games.(现在进行时改为过去进行时）
特殊He said "The earth goes around the sun."
改 He said that the earth goes aroung the sun.(当直接引语中表示客观事实时,时态不受主句影响）
3.直接引语变间接引语时,要注意时间状语的改变.
e.g.He said ‘I am listening to music now."
改He said that he was listening to music then.(此句中now改为then)
后面不举例了,时间状语按下面改就对了
now=then
today=that day
tonight=that night
this morningweek=that morningweek
tomorrow=the followingnext day
yesterday=the day before
last mouth =the month before
ago=before
here=there
（上面左为直接引语中的时间状语,右为间接引语的时间状语）
4.最后是指示代词要变
this改为that
these改为those
我自己总结的,你看看吧.有没有用
