间接引语不改变时态的情况

如果说的事情仍然还没有发生，即转述时还没有发生，可能转述时间距离原话说的时间不长，说的内容还是事实，那么时态就不会往回退，不会变成过去时态。一般是原话是将来时，或是一般现在时，现在进行时，或现在完成时，会有时态不发生变化的情景。

He told me his brother works for an Italian company. 
他告诉我他哥哥在一家意大利公司工作。
[说明转述时他哥哥仍然在这家意大利公司工作，这仍然是事实。如果是 He told me his brother worked for an Italian company 说明转述时他的哥哥已经不在这家公司工作了。]

She said she's getting married next year.
她说她明年就要结婚了。

she's getting = she is getting
[说明这句话的说话时间是“this year今年”，她还没有结婚，所以时态不发生变化。如果说话时间已经是“next year下一年”或更晚，时态就要变成过去时 She said she was getting married next year. 她说她下一年就要结婚了。]

He said he's finished painting the door.
他说他已经把门漆好了。

he's finished = he has finished
finish (+ doing) 动词，完成，完结，结束
paint 动词，刷油漆；（用颜料）画，绘
[说明他可能是刚刚、很短时间之前说的话。如果是几天前或更早说的就要把时态变为过去完成时了 He said he had finished...]

She promised she'll help us.
她答应会帮助我们。
promise 动词，承诺，保证，答应
[说明这一承诺也适用于（转述的说话时间之后的）未来。]
