About twenty of us had been fortunate enough to receive invitations to a film-
studio（影棚）to take part in a crowd-scene. Although our "act" would last only for a short time, we could see quite a number of interesting things.
We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera waswheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.
The next scene was a complete contrast(对比).The way it was filmed was quite
unusual. Pictures taken on an island in the Pacific were shown on a glass screen. An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!
Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film”Stars”!
下面是我翻译出来的，帮忙把剩下的翻译完并检查一下有没有翻译错的。
我们当中将近20人很荣幸地收到前往影棚参加电影拍摄的邀请。尽管我们的节目最终只有短短的时间，但我们完全可以看到有趣的事情。我们所有人站在影棚的那一端，作为工作人员准备拍摄这个场景。不久，明亮的灯打开了，大型电影摄影机转到了指定的位置。导演对摄影机操作者大声交待一些事情，然后走到两个著名的演员旁边交谈。Since it was hot in the studio, 当演员们这些穿上厚重的衣服开始沿着路线走过令我们惊讶不已。一台大风扇从他上面吹出细小的白色羽毛，强烈的风吹过这些树。这个画面给我们带来的寒冷的感觉看起来十分真实。
接下来的场景跟前面完全相反。The way it was filmed was quite unusual。大西洋的画面展现在玻璃屏幕上。一名男演员和一名女演员站在屏幕前面，以使得他们看起来就好像在岛上的水面旁边。通过像这样简单的诡计，棕榈树，沙滩，还有清澈的蓝天已经呈现在影棚中。
紧接着就是我们的拍摄时间，we were left wondering what scene would be prepared for us.在接下来的三分钟的时间里我们体验到成为明星的兴奋。
