We live in the computer age. People use computers to do much of their work. But few people know how to look after them. Remember the following when you use your computer:
1.Keep your computer in a cool, dry room. Too much or too little heat is bad for computers. Damp(潮湿) is also bad for them.
2.Do not let people smoke near your computer. Smoke of all kinds is very bad for many parts of a computer.
3.Do not eat or drink when you are near your computer. Pieces of food and a little water in the keyboard are also bad for a computer.
4.Keep your screen clean and do not have it too bright. They are bad for your eyes. Make sure the screen is not too far from or too near your eyes. Some people use different glasses to protect their eyes when they use a computer.

Here's an interview to a pilot about his life.
(R="Reporter;" P= Pilot)
R: How much time do pilots actually spend flying a plane?
P: It varies (WES'J) from about 20 minutes on some domestic (区别) flights to as much as 18 hours on international flights. It all depends on if the flight is a short- or long-haul flight.
R: Do pilots take breaks during flights or do they fly the whole time?
P: Yes, we take breaks during long-haul flights. Airlines assign (指派) three or four pilots to long flights. We take turns flying the plane.
R: If pilots are traveling all the time, how do they deal with jet lag (时差)?
P: Jet lag is annoying for almost all pilots. I try to go to sleep as I would at home.
R: How important is it to know the weight and size of the plane you are flying?
P: It is very important. We weigh almost everything put into the airplane and make estimates (估计) according to the number of people on each flight.
R: Do pilots eat the airplane food?
P: Yes, we eat business class food! Airplane food changes every season and is very delicious if you don't hate eating lobster (龙虾) every day! The pilots on the same plane are supposed to make different meal choices so that if one of the dishes causes food poisoning, only one of them will be sick. That way, at least one pilot will always be well enough to fly the plane!

Nowadays, computer games are becoming more and more popular in many cities and towns. A lot of small shops along busy streets have been made into small game houses in order to get more money. These places are always crowded with people, especially young boys.
In the computer game houses, people spend a lot of money competing (较量) with the machines. It's hard for one to win the computer, but one can make progress after trying again and again.

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 minefield. 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 the 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.

Do you play a musical instrument? If so, you may be getting smarter. A recent study shows that taking music lessons can raise a person’s IQ.
Scientists studied 132 children in Canadian schools. At the beginning of the school year, these children took an IQ test. Then they were divided into four groups. One group took singing lessons. Another group took weekly piano lessons. The third group took classes in drams(戏剧). And the last group did no special activities at all.
At the end of the school year, the 132 children took an IQ test again. In all four groups, the average score went up. However, the piano players’IQs went up 7.0 points on average. The average increase for the other three groups was only 4.3 points.
The researchers say that the difference is small and it may not result in better grades for the piano players. However, they still consider the results important. Learning an instrument helps kids becomes better at concentrating and at memorizing things. Therefore, the researchers say, it may be good for brain development in young people.
If you have a chance to learn to play a musical instrument, never miss it. Remember it can make you smarter.
