    　　She asked us to choose a topic．make a weekly plan and tell the class about it．Then we had to do things to be“green”and write a report about our success．Some students said that they thought it was impossible for a single person to contribute to the protection of the environment．Someone else said that scientists should work harder to find new ways to produce energy．

    　　Frau Keller said that it is everyone's job to care for the health of the planet．(2)After the first week everybody in class was excited about the project and wanted to continue to improve their results．Someone suggested telling the other classes in the school．Now all 768 students at Hermann Stein School are working on the project．At the end of the year, our class will write a report about what we have done．

    　　(3)下星期我将会考虑怎样不会浪费水或者污染水．I'm planning to try and use less water every day, and also not use so much of the things that make it dirty．Every time I turn on the tap(水龙头)I must think about how much water and soap I use．

    　　At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars．Our own planet, Earth, is becoming more and more crowed and polluted．Luckily, we can start again and build a better world on Mars．Here is what life could be like．

    　　First of all, transport shouldnbe much better．At present, our spaceships are too slow to carry large numbers of people to Mars－it takes months．However, by 2100, spaceship can travel at half the speed of ligh．It might take us two or three days to get to Mars!

    　　Secondly, humans need food, water and air to live．Scientists should be able to develop plants that can be grown on Mars．These plants will produce the food and air that we need．However, can these plants produce water for us? There is no answer now．

    　　There is a problem for us to live on Mars．Mars pukkss us much less than the Earth does．This will be dangerous because we could easily jump too high and fly slowly away into space．To prevent this, humans on Mars have to wear special shoes to make themselves heavier．

    　　Life on Mars will be better than that on Earth in many ways, People will have more space．Living in a large building with only 10 bedrooms is highly possible．Many people believe that robot will do most of our work, so we have more time for our hobbies．

    　　There will probably be no school on Mars．Every studetn will have a computer at home which is connected to the internet．They can study, do their homework and take exams in online schools．Each student will also have their own online teacher called“e-teacher”．

    　　However, in some ways, life on Mars may not be better than that on the earth today．Food will not be the same－meals will probably be in the form of pills and will not be as delicious as they are today, Also, space travel will make many people feel ill．The spaceship will travel fast but the journey to Mars will probably be very uncomfortable．
