do you know about the incident reported at Roswell， New Mexico in 1947？

Many people believe that aliens crash-landed near Roswell in July 1947. A farmer said that he found wreckage1 made of unusual metal that many think was from a flying saucer2. The United States military3 collected the wreckage and at first announced that it was indeed from a flying saucer. However， soon after， military officials insisted4 a mistake had been made， and that the wreckage was from a weather balloon. For many people， the truth about the Roswell incident remains a mystery5.

Anyone interested in UFOs and aliens6 would probably want to visit the International UFO Museum and Research Center， which was founded in 1991 in Roswell.

UFO is an abbreviation7 for “unidentified flying object，” which is an object in the air that cannot be easily explained. Over the years， many people say they have seen UFOs. However， the objects usually turn out to be things that can be explained， such as meteors8， balloons， or even birds.

知道1947年美國新墨西哥州罗斯维尔市报道的事件吗？

许多人相信，1947年7月，有外星人坠毁在罗斯维尔市附近。一名牧场主声称，他发现了由异常金属制成的残骸，许多人认为该残骸来自一个飞碟。美国军方收集了残骸，一开始，他们宣布残骸确实来自飞碟。然而，军方官员很快坚称之前说法有误，他们称残骸来自气象气球。对许多人来说，罗斯维尔事件的真相仍然是个谜。

任何对不明飞行物和外星人感兴趣的人都可能想参观1991年在罗斯维尔成立的国际UFO博物馆和研究中心。

UFO是“不明飞行物体”的缩写，它是太空物体，不易解释。多年来，很多人说他们看到过“不明飞行物”。但是，这些物体通常被发现是可以解释的东西，如流星、气球，甚至是鸟类。
