Behind this song,there is a touching story.This band in the beginning have（改为has） four men.(我觉得这里整体改为There were four men in the band in the beginning更好.）.A boy and a girl are (改为过去式were) lovebird（改为复数lovebirds） ,but the girl suffering（改为动词过去式suffered,否则该句子中没有谓语.） from terminal uremia.The boy want（改为过去式wanted） to have contributed to(去掉to,contribute to 表示“向……捐献”,) （ his a kidney）（这里改为one of his kidneyes）,but the doctor didn’t agree with him.Those time(time时间,是不可数的.不能用those,改为That),he only has (注意时态.过去式had)two affair(有two ,用复数):accompany with（去掉with,accompany 是及物动词） his girlfriend or create music.Last（At last）,the boy pass(改为passed) away,and contributed to his a kidney（改为one of his kidneyes）to his girlfriend.In the boy's funeral,the girl wear（改为过去式wore）(dress是可数名词,前加a或者the) wedding dress.When the boy coffin(用过去式) for burial ,she pass(过去式passed) out again.She never come(用过去式) to again.
因为讲的是一首歌背后的故事.发生在过去.所以整体时态应该是过去式.因为有些地方不知道要表达什么意思,所以词组的使用我没怎么修改.比如最后的pass out和come to
