丹尼尔想找到更多关于将来太空上的生活。他发现了下面这篇文章，它是由一位著名的科学家所写，这位科学家认为到下个世纪为止人类能够住在火星上。

Moving to Mars

搬往火星

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。

So far, nobody knows whether there would be enough water or oxygen on Mars for people there. Moreover, scientists are not sure whether plants could grow on Mars. Food would most probably be in the form of pills and wouldnot be so tasty.

到目前为止，没有人知道火星上是否有足够的水和氧气供人类生存。而且，科学家也不确定植物是否能在火星上生长。食物很大可能会以药片的形式存在，而且味道没那么可口。

Gravity could be another problem. The gravity on Mars is only about three-eighths of that on the Earth. Peoplewould have to wear boots that are specially designed to prevent themselves from floating off into space.

重力可能会是另一个问题。火星上的重力大约只有地球上的八分之三。人们可能得穿上特殊设计的靴子，防止自己漂浮到太空中去。

Compared with life on the Earth, life on Mars would be better in some ways. People would have more space. Theymight live in houses with huge comfortable rooms. Also, robots would do most of their work so that they could have more time to relax.

与地球上的生活相比，火星上的生活在有些方面要好些。人们会有更多的空间。他们可能住在房间又大又舒适的房子里。而且机器人会帮他们做大部分的工作，这样他们就有更多时间来放松。

There would probably be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online schools with "e-teachers".

火星上可能没有学校。每个学生家里都有一台电脑与星际网络连接。他们可以跟电子教师一起在网上学校学习。

Life on Mars would be interesting as well as challenging.

火星上的生活，不仅有挑战性，还很有趣。
