Do you hope to move to another city or a foreign country?It may be interesting．But how about moving to 1 planet?A US company now has a plan：sending people to Mars 2 20 years．
To begin with,the company plans to send 3 people to go to Mars first．It will 4 them several months to get there．When they arrive,they will build a 5 first．
But Mars is not an easy place to 6 ．It is rocky,cold and has lots of sandstorms(沙尘暴)．Also,there is 7 air for breath．So people would have to live in a special house．They would have to 8 special clothes if they go out．
People will have to find 9 resources(资源),iron,water and so on．All these could help people live there…
Sounds interesting?You might want to go to Mars now． 10 will things go well as the company hopes?We'll wait and see．

It's important to learn how we can protect the environment．Here are 5R rules for us．
Reduce：If you want to reduce waste,you should use things more wisely． 1 If everyone uses paper carelessly,soon we would not have any trees left．Other things are also being wasted,and people don't know what to do with the waste in big cities．So it is necessary to reduce the amount of waste we produce．
Reuse：You should always think of reusing things before throwing them out．For example, 2 In a family,you may pass on such clothes to younger brothers or sisters．
Recycle：Bottles,cans and paper can easily be recycled．By doing so,we save lots of time and money．For example, 3 The metal can be used to make new Coke cans．
Recover：When you buy a box of apples,there may be a few rotten ones．You have two choices：One is to throw the apples away;the second is to throw the rotten ones and keep the good ones．In this way,you are recovering the eatable parts of food．
Repair：If one of the legs of your table is broken,you should repair it．If you want to buy something newer and better,it is better for you to sell the old table,or 4 ．
Learn the rules to protect our environment．Let's try our best to make the earth cleaner and more beautiful．
