Have you ever rubbed(擦) your hands together when they get cold? Why do we do that? We do that for friction(摩擦). 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!

●________1.__________

Soap        Water         Your hands

●________2._________

(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.

●________3.__________

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.

●________4._________

(1). Friction happens when you stop your fast running bike.

(2). Ancient people made fire by rubbing two pieces of wood together. Friction happened though they didn’t know it.

●_______5.________

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.

Now satellites(卫星)are helping to forecast(预报)the weather. They are in space and they can reach any part of the world.The satellites take pictures of the atmosphere(大气), because this is where the weather forms(形成)。They send these pictures to the weather station. So meteorologists(气象专家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures,the meteor- ologists compare(比较)them with earlier ones. Peerhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change,too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon,perhaps , they may be ablet to forecast the weather for a week or more ahead(提前)

Everyone needs friends. Friends bring us happiness and hope in our lives. But the ability to make friends changes from person to person. To some people, making friends is easy, and to others it’s very difficult.
Making friends is a skill, and the first thing is to know how to get along with others.
If you have trouble in making friends, maybe I can tell you how to do it.
★Realize your own good points. You have skills and talents that others will like.
★Believe that you are a good person and have something nice to share with others.
★Be humorous. Learn to laugh at yourself and your weakness. Remember to smile to others.
★Respect others. Everyone has his own idea. Learn how to listen to others’ ideas without trying to make them accept yours.
★Be kind. If you are kind to others, they will usually be kind to you. There are hundreds of little things you can do to show kindness. Open the door for someone. Wave to a friend and so on.
★Don’t complain. Learn to accept what you can’t change, and work hard to change what you can. No one is willing to hear your complaining all the time.
★Never give up. Even if you are faced with some closed-minded people, never give up. And try to find someone who will understand you.
