Moving to Mars
移居到火星
Some people believe that humans could live on the planet Mars by the year 2100. Our own planet, the Earth, is becoming more and more crowded and polluted because of the rapid increase in population. It is hoped that people could start all over again and build a better world on Mars. Here is what life there could be like.
有些人相信到2100年人类可以在火星上生活。我们自己的星球，地球，因为人口的快速增长正在变得越来越拥挤，污染越来越严重。人们有望能够在火星上重新开始，建设一个更好的世界。这里描述的是火星上的生活可能是什么样子。
At present, our spacecraft are too slow to carry large numbers of passengers to Mars--it would take months. With the development of technology, by the year 2100, the journey might only take about 20 minutes in spacecraftthat travel at the speed of light! However, the spacecraft would travel so fast that the journey to Mars mightbe quite uncomfortable. Many people would feel ill.
目前，我们的宇宙飞船太慢了，无法运送大批的乘客去火星——因为要花几个月的时间。随着技术的发展，到2100年，乘坐以光速飞行的宇宙飞船，行程或许只要大约20分钟！但是，宇宙飞船的飞行速度如此之快，可能会导致到火星的行程相当不舒服。很多人会觉得不舒服。
Humans cannot survive without water, oxygen or food.
没有水、氧气和食物，人类无法生存。
