Welcome to the unit
Daniel is talking to Amy about living on Mars. What would it be like? Work in pairs and discuss with your partner. Use the conversation below as a model. 丹尼尔正在和埃米谈论火星上的生活。它会是什么样子呢？结对练习，与同伴讨论。用下面的对话作为示范。Daniel:What would it be like to live on Mars?丹尼尔：住在火星上将会是什么样子呢？Amy：There's less gravity on Mars. We'd probably need to wear special boots.埃米：火星上重力小。我们可能需要穿特殊的靴子。Daniel:Yes. And we might need sleeping bags too.丹尼尔：是的。我们可能也需要睡袋。Amy:l agree. Also,there's no fruit or vegetables，so we would have to eat dried food．埃米：我赞同。而且没有水果和蔬菜，所以我们将不得不吃干粮。Daniel: Well... that sounds quite boring! But there would be no pollution on Mars.丹尼尔：嗯……那听起来相当无聊！但火星上将没有污染。Amy:l hope so.埃米：我希望如此。
Reading
Daniel wants to find out more about life in space in the future. He has found the following article by a famous scientist who thinks humans could live on Mars by the next century.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。
Integrated skills
A1Host: Is there water on Mars? Should we move there? What would life be like there?These are the questions that were asked when a survey was carried out in schools in Sunshine Town. The survey showed that fifty per cent of the students would like to move away from the Earth.On Friday evening, live on Sunshine TV, some students will discuss these questions. To find out what they think, make sure you watch Moving to Mars, from 7: 30 p.m. to 9 p.m., here on Sunshine TV.A2Host: Hello, welcome to today’s discussion. Recently, we carried out a survey to find out what students think about the future. Interestingly, fifty per cent of the students would like to live on another planet, such as Mars. Today, we’ve invited three students to join us in the discussion. Let’s see what they think. Penny, Sarah and Tony, what do you think about living on Mars?Penny: I’d love to live on Mars. I think it would be very interesting. We could study at online schools.Sarah: Oh no, I’d hate to live on Mars. We don’t know if it would be really safe. We might get ill from living there.Penny: No, it would be very safe. Also, if we went to live on Mars, there would be much more space. We wouldn’t have to live in crowded cities like we do here on the Earth.Host: Tony, would you like to live on Mars?Tony: I’m not sure. Since Mars is so far away from the Earth, what if I find I don’t like living there and want to come back?Penny: Then you would just need to get on a spacecraft and fly back home. Travelling in space would be fun.Sarah: I still don’t think Mars is a good place to live. There isn’t enough food, water or oxygen. There might even be dangerous aliens.Penny: I’m sure there’s water somewhere on Mars, and in the future, there would be plenty of food, water and oxygen.Tony: If the Earth becomes too seriously polluted, perhaps we’ll have no choice but to move to Mars.

It would be quite safe.

It's just a different kind of life. It would be great to live on another planet.丹尼尔：桑迪，我不这样认为。它只是一种不同的生活方式。生活在另一个行星上会很棒。Sandy:What about all your friends here on the Earth if you go to Mars?桑迪：如果你去了火星，地球上你所有的朋友怎么办？Daniel：I want you all to come too.丹尼尔：我想让你们所有的人也都来。Sandy:OK.
