Different weather makes people feel different. It influences health, intelligence(智力) and feelings.

In August, is very hot and wet in the southern part of the United States, People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.

The weather can also influence intelligence. For example, in a scientific report, IQ (智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).

Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.

Low air pressure may make people forgetful. People leave more bags on buses and in shops on low-pressure days. There is a "good weather" for health. People feel best at a temperature of about 18℃.

Are you feeling sad, tired, forgetful, or unhappy may be the weather's problem today?

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.

We each have a memory(记忆力). That's why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.

    When you are in England, you must be very careful in the streets because the traffic drives on the left. Before you cross a street, you must look to the right first and then left. If the traffic lights are red, the traffic must stop. Then the people on foot can cross the road.
    If the traffic lights are green, the traffic can go. People on foot mustn't cross. In the morning and in the evening when people go to or come from work, the streets are very busy. Traffic is most dangerous then.
    When you go by bus in England, you have to be careful, too. Always remember the traffic moves on the left. So you must be careful. Have a look first or you will go the wrong way.
   In many English cities, there are big buses with two floors. You can sit on the second floor. From there you can see the city very clearly. It's very interesting.

  Energy is becoming less and less. It is a problem in the world. Many people are worried about that there will be not enough energy for people to use if they use them in a wrong way.
  Most people agree that the problem can be solved (解决) in some ways. One is to save the energy. For example, some countries use daylight (目光) saving system (系统) instead of electricity for lighting. In other countries, if people use much electricity, water and farm land, they have to pay much for it.
  But only saving cannot solve the problem. There is another way, which is to develop new energy. People can develop much other energy such as nuclear power (核动力) and water power.
    If people do well in these ways, I believe people can solve these problems of energy and save much energy for themselves.

Why do plants grow in some places and not in the others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all?

To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why dry deserts everywhere are almost not covered by trees or grass.

Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.

Another thing plants must have before they can grow is food.

What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won't. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

According to a new study, cats may be just as smart as dogs. Both cats and dogs may have episodic memory（情景记忆）, similar to that of human beings.

The discovery shows that cats can recall memories of positive experiences like eating a delicious snack. The study was a test of episodic memory. Episodic memory means memory of past experiences that happened at a special time and place.

In the test, cats were led to four open bowls of food. They were allowed to eat from two of them. After fifteen minutes, empty bowls took the place of the old ones. Then the same cats returned to look for food again. They spent more time searching for the old bowls.

It seemed that the cats were able to remember the information of “what” and “where” about the bowls. This discovery suggests that they may have episodic memory. However, it's still not clear whether cats can truly experience past memories in the same way as human beings do. “It's difficult to know whether the cats can subjectively（主观地）remember the experience,” Nick Diamond, a researcher at the University of Toronto, explained.

Still, the test plays an important role in the development of memory research in animals. “It opens the door to new studies. How long can cats' memories last? We may do some research on this in the future,” Professor Laurie Santos from Yale University told BBC News.

The road to new discoveries is long and difficult. Though there are lots of problems to be solved and discussed along the way, such studies do lead us a step closer to the final success.
