直接引语变间接引语的问题！！！！

Mr.smith says, "I will sell my house."变为间接引语Mr.smith says that he will sell his house." 另外一句是He said,"I will do it here"变为间接引语He said that he would do it there.
请问同样主句是一般将来时，为什么前一句的时态没变、而后一句的却变了？
还是说这样变是不正确的！！！！

3、直接引语变成间接引语时，从句时态无须改变的情况
　　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.
　　5）当直接引语是客观真理或自然现象时，如：
　　Our teacher said to us, “Light travels faster than sound.” ——>
　　Our teacher told us that light travels faster than sound.
　　6）当引语是谚语、格言时，如：
　　He said，“Practice makes perfect.” ——>He said that practice makes perfect.
　　7）当直接引语中有情态动词should, would, could, had better, would rather, might, must, ought to, used t-o, need时，如：
　　例如：
　　The doctor said, “You'd better drink plenty of water.” ——>
　　The doctor said I'd better drink plenty of water.
　　He said, “She must be a teacher.”——> He said that she must be a teacher.
　　He said, “She ought to have arrived her office by now.”——>
　　He said that she ought to have arrived her office by then.
　　The teacher said, “You needn't hand in your compositions today.”——>
　　The teacher said we needn't/didn't need to/didn't have to hand in our compositions.
　　She asked, “Must I take the medicine?”——> She asked if she had to take the medicine.
　　〔注〕：此处用had to代替must更好
　　8）此外转述中的变化要因实际情况而定，不能机械照搬，如果当地转述，here不必改为there, 动词come不必改为go，如果当天转述yesterday, tomorrow, this afternoon等均不必改变。如：
　　Teacher: You may have the ball game this afternoon.
　　Student : What did the teacher say, Monitor?
　　Monitor: He said we might have the ball game this afternoon.

不明白的再问哟，请及时采纳，多谢

直接引语变成间接引语时，从句时态无须改变的情况 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

，直接引语在改为间接引语时、时态需要做相应的调整。
　　现在时它需改为过去时态；过去时态改为完成时；过去完成时则保留原来的时态。如：
　　1)She said. "I have lost a pen."→She said she had lost a pen
　　2)She said. "We hope so."→She said they hoped so.
　　3) She said. "He will go to see his friend。"→She said he would go to see his friend

Answer 2

首先要弄清楚这两句哪个部分是主句。
Mr.smith says that he will sell his house 中 Mr.smith says 是主句，that he will sell his house 是宾语从句。
He said that he would do it there 中 He said 是主句， that he would do it there 是宾语从句。
第一句的主句是一般现在时，第二句的主句是一般过去时。
直接引语变成间接引语时，从句时态改变的情况
1.如果主句是现在的时态（如一般现在时，现在完成时等），从句一般时态不变。
2，如果主句是过去的时态，（如一般过去时，过去完成时），从句就变化，
从句原是 一般现在时------------》一般过去时
一般过去时-------------》 过去完成时
现在完成时------------->过去完成时
过去完成时-------------》过去完成时
一般将来时-------------》过去将来时
现在进行时--------------》过去进行时
所以第一句的主句是一般现在时，从句不变
第二句的主句是一般过去时，从句由一般将来时变为过去将来时
