Have you thought of moving to another planet? An American company now has a new plan: sending people to Mars (in) twenty years.
To begin with the company plans to (send) a few people to Mars first.It will (take) them months to get there
But Mars is not a (good) place to live on.It's rocky(多岩石的），cold and has lots of sandstorms(沙尘暴）,Also,there is (no) air for breath.So people hace to live in a special house.There is air in it.They have to (wear) special coothes when they go outside.
(How) would people live there? They have to make daily things like knives. Ther will hace to (find) useful resources(资源）.There is CO2(O下面一个小2） in the air water in the ice and some other useful things.All there could help people live there...Sounds (interesting)? You might want to go to Mars now.(But) will things go well as the company hopes?We hace to wait and see,.
