Project Assessment Further study 一实践·注重应用评价 对接“单元活动”一让活动有效开展 本板块要求结合本单元所学的语言知识和文化知识，完成一项关于如何在外 星球生存的解决方案。为完成该任务，应首先对某一外星球展开深入探究，多渠 道获取信息。在形成解决方案的过程中，可以参照课本范例，对所获信息进行合 理的梳理与整合，有针对性地依据预设的挑战，制订相应的解决方案。 [活动“助手] Interesting facts about the Red Planet: 1.Mars is the fourth closest planet to the Sun.It is 141 million miles away from the Sun.It has two moons.A year on Mars is 687 Earth-days long. 2.Mars has seasons like Earth,but the seasons on Mars are twice as long as the seasons on Earth. 3.Mars also has an atmosphere,but it is very thin and made up mostly of carbon dioxide.Because of its thin atmosphere and greater distance from the Sun,Mars is much colder than Earth. 4.The Earth's atmosphere is 21%oxygen,but it is only 0.13%on Mars.Carbon dioxide makes up 96%of the atmosphere on the red planet. 5.Mars is about half the size of Earth.Because Mars is smaller than Earth,its gravity is also less. 6.Mars'surface looks like a red desert.There are mountains,canyons ()and craters (k).There are no rivers or oceans.It is a dry planet without any liquid water(液态水). [活动任务] 根据[活动"助手"]中有关火星的信息,以Lifeon Mars为标题写一篇短文,在 英语课上与同学们分享. Life on Mars It's an honour to stand here togive my speech, whose topic is "Life on Mars". ____________ __________ _____________ Thanks for your listening! 参考范文： Life on Mars It's an honour to stand here to give my speech,whose topic is "Life on Mars". As we know,there is little oxygen on Mars and also it is much colder than our planet,so people need to put on the spacesuits,which allow them to breathe and protect them from exposure to the cold and radiation.Gravity could be another problem.People would have to wear boots that are specially designed to prevent themselves from floating off into space. Compared with life on Earth,life on Mars would be better in some ways.People would have more space.They might live in houses with huge comfortable rooms.Also,there would probably be no schools on Mars.Every student would have a computer at home connect
