英语翻译亲爱的朋友,很高兴在和你写信.我们是一年前的“姐弟”,今天虽然分离,但我还是在脑子里回响你以前的情景.希望你能有

dear friend: How are you? I am happy to write letter to you! We were the sister and brother one year before.Eventhough wo are in different place now,but I still remember the previous scence ...

梦想之眼泪的 translation is okay
but we'd better modify it
in the third line,no"letter",
put "the"just before"brother"
change "place"into "places",change "wo"into "we" in the fourth line and cross"but"
i don't know what "scence"is(are you sure the spelling is right)
