boys and girls, good morning,today i'll bring you an interesting story--a big email mistake.If you’ve already heard this story, please don’t stop me because it’s the only one I know. now, i'll begin to tell you the story.from this story, we could find we need to be careful with everyting. because maybe it is only a small mistake for you, but it would cause a fatal result for others. i hope in our future life, we would be responsible for everything and never make such mistakes. that's all.thank you.不知道这样可以嘛,写得可能不怎么好-0-
