What will life be like in 100 years? Some people believe that humans could live on the planet Mars by the year 2100. The Earth will be crowded and there will be more 【小题1】 (pollute) then. It is hoped that people could build a 【小题2】 (good) world on Mars. Here 【小题3】 (be) what life there could be like in the future.

Humans can’t live without water, air or food. So far, nobody 【小题4】 (know) whether there would be enough water or air on Mars for people. Moreover, scientists are not sure whether 【小题5】 (plant) could grow on Mars. Food would most possibly be in 【小题6】 form of pills (药片) and would not be so tasty.

Compared 【小题7】 life on the 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, robots would do a lot of 【小题8】 (they) work so that they could have more time to relax. There would 【小题9】 (probable) be no schools on Mars. Every student would study at online schools with “e-teachers”.

Life on Mars would be interesting 【小题10】 challenging. However, it takes time. So the most important thing we need to do now is to protect our planet—the Earth!
