Here in Siberia (西伯利亚), the winter is always very long and it’s very, very cold! It starts to snow in November and the snow won’t leave until May. The temperature is usually about -25℃, but it’s sometimes much colder. When it’s -35℃, children can’t go to school, but grown-ups still go to work! We wear a lot of warm clothes: socks and boots, sweaters and fur coats. All the houses have heating, so it’s never cold inside. In winter, we close the windows to stop the wind from getting in, and we don’t open them again until spring.
In spring and summer it rains a lot, and we don’t often see the sun. In summer it’s often about 25℃, but the weather is very changeable. One day it’s 25℃, and the next day it’s 10℃. People say that the weather was even colder in the past.
Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let’s discover friction!
| WHAT YOU’LL NEED: ● Soap● Water● Your hands! WHAT TO DO: 1. Make sure your hands are dry. 2. Rub your hands together until you feel the heat of your hands. 3. Now, use soap and water to get your hands very slippery (滑的). 4. Try to make friction happen while your hands are slippery. 5. Please write down what has happened. LET’S TALK! Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot. DID YOU KNOW? 1. Friction happens when you stop your fast running bike. 2. Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it. ? Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (轮胎) of the car before and after a short drive to see how much warmer they get from friction. |

Some people think only school children do not agree with their parents, however, it is not true.
Communication is a problem for parents and children of all ages. If it’s hard for you to communicate with your parents, don’t worry about it. Here are some advice for you to bridge the generation gap (代沟).
Don’t argue (争辩) with your parents. Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.
Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael’s mother didn’t agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.
Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect (尊敬) to them. Showing respect will keep your relationship strong.
Talk about your values. The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person. It is worth having a try!According to the passage who have a communication problem?

What do people do with their old, out-of-date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown out with the rubbish.
Some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products. Dell, Hewlett-Packard and other companies now also take back some old computers.
In some countries, laws are being passed, too. Computer companies will have to collect and recycle their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.
The computers then go to schools, charities and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things—and cut down on waste, too. How do people usually deal with their old computers?
