“丁零零”，我被一阵闹钟声吵醒了。我睁开眼睛一看，觉得这地方怪怪的，什么东西也没有。我急忙大声说：“我在什么地方？”一个机器人闻声而来，对我说：“我是机器人麦克，这是你的家，你已经来到了2030年。”“什么？我的家？2030年？”我又问：“这里怎么什么都没有？”麦克没有作答，只是按了一下墙上的\'黄色按钮，各种东西都从墙里伸出来了。“哇，真棒。”我不禁叫道。麦克对我说：“咱们出去转转吧！”外面没有宽阔的马路，只有步行街，两旁有自行车道和专为残疾人提供的传送带。步行街两旁是林立的高楼大厦，供辛苦一天的人们休息。“咦？汽车跑哪里去了？”我问。麦克指了指天上，原来汽车成了和飞机一样的交通工具，这种汽车没有尾气，而且想停那就停那儿。麦克仰着头对我说：“天上的巨伞是工程师们精心设计的，可以挡风、遮雨。”我连忙拍手叫好。麦克又对我说：“现在全世界的东西都可以在广场买到，非常方便。”
回到家，我发现房间里干干净净，麦克告诉我：“这都是房间里的排污系统做的，这个房间还可以抓小偷、报警，可方便了。”
晚上，我按了一下按钮，又回到了现实世界。

the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.

一天早上，我的机器助手大刚急切的`叫醒我，说：主人，30分钟后会有一场12级大地震，快起来！现在，12级的大震已是家常便饭了。我无可奈何的起床，简单洗漱完后，把房子放在地下后（为了地震才发明的）坐着太阳能三用车飞快的开到一小片树林里。嗨，目前，树林在急剧减少，人们常常想起小时后那美好的家园，怀念小时候那美好的环境。达达一辆气垫摩托的喇叭打断了我的美梦。这时，树林里挤满了车。10分钟后，警报解除，人们陆续回家了，在路上，我看见到处都是黄沙，树木寥寥无几，我大叫到：这是我的家园吗？可没人回答，只有大刚对我说：主人，上空大气层有空洞，紫外线很强，请快离开！我只好离开了
回到家后，我花了一个星期的时间发明了一个时光机，马上用它回到公元2004年。
叮叮叮闹钟叫醒了我，我马上跑到窗前，看到了美丽的风景，我高兴地大叫：太好了，美丽的家园没变！就这样，新的一天又开始了。
