5. Mars
火星是太阳系九大行星之一，火星是距太阳的第四个行星，它的体积在太阳系中居第七位，是类地行星中距离太阳最远的一颗，位于地球和小行星带之间，它外观呈现出火红色，因而非常引人注目。火星有两颗小型天然卫星：火卫一和火卫二。
火星的表面沙砾遍地，十分荒凉沉寂，遍布遭陨星袭击后因撞击形成的坑坑洼洼。

6. Mars 火星平均气温为零下五十五摄氏度,温差较大：在夏季的昼间，气温最高为二十摄氏度，而在冬季，气温则可低达零下一百多摄氏度。
火星上经常有强风，因而常导致大范围的尘暴。它大气非常稀薄，它的主要成份是二氧化碳，其他成份还有氮、氩、氧等。水在火星大气中的比重只有百分之零点零三。因而火星表面异常干燥。

You also want to write a guide to living on Mars. First, make a spidergram like Daniel’s on page 62. Then write the guide and include some drawings.
Sample writing:
What will our life be like on Mars in the future? With the rapid development of hi-tech, the Mars will change a lot in many ways in the future. We'll completely live in the cyberspace. First, we find the Mars haven't been polluted. Air and water becomes more tidy and fresh than our earth. Second, if we want, we can study in the spaceship.

26. And people don't need to go to the factory to work, instead of working by computer at home. On the other hand, it is very easy for us to visit the Earth and other stars by riding spaceship. I hope all this can come true. But first, we must treasure and protect Mars and avoid it becoming another polluted earth. If all of us try our best to do it, we will enjoy our life.
