It’s important to learn about protecting our environment. Here is a 5R rule for us:
1. Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, 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 waste
2. Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
3.  Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted (融化) and the melted things are made for new coke cans.
4.  Recover
When you buy a box of apples, there may be a few rotten（腐烂的）apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
5.  Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a “throw-away” society（社会）. But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

There are few families in the United States that do not have either a radio or television set. Both of them have become a necessary part of our daily life, keeping us filled with the news of the day, teaching us in many fields of interest, and making us happy with singing, dancing and acting.
Marconl, the Italian inventor, who gave us the radio, probably didn’t know how much his great invention would have done for the world in the years to come. Radio had, perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happen. Travelers in or out of–the–way places, ships at sea even astronauts round the earth are able to keep in touch with each other by radio.
Television is another important invention. It lets us see as well as hear the actor. Since its appearance, TV has done a great deal in the daily life of people everywhere. Many programs are now televised in color.
Perhaps the most modern invention is “Telstar”, a “star” moving round the earth. It makes it possible for the people all over the world to be closer than ever before. Now a family in Chicago can watch on TV a motor–car race in Italy, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!

There are about 80,000,000 mines*  under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50  people including many children were’ killed ‘or htirt each iay.  In 2003,  APOPO,  a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng rats to search for the mines.
The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp*  sense of smell.  The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana.  The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’  training, the rats were taken to a minefiel山  They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers*  that they smelt out’a mine.  Then the mine was cleared. It had  taken two ‘deminers  a day to clear a 200㎡ . minefield,  but with the help of two rats ‘they could finish it in two hours.
The rats and ~he deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.
