Different weather makes people feel different.It has an effect on health，intelligence(智力) and feelings.

In August，it 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 1983 report by scientists, the 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% lower.The wind can help people have higher intelligence.Very hot weather，on the other hand，can make it lower.Students in many schools of the United States often get worse in exams in the hot months of the year(July and August)．

Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people's depression (沮丧) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I'm watching TV, he'll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people's minds.”

In 1620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn't want to copy the USA's example. We're planting more and more trees. We've built the " Great Green Wall" of trees across northern part of our country. The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More "Great Green Walls" are needed. Trees must be grown all over the world. Great Green Walls will make the world better.

The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.
◆Try to use new information immediately*. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say "________"
◆Break a big number into smaller parts. For example, it's hard to memorize 109244153. But if you break it into three parts--109/244/153—it becomes easier.
◆Write out what you need to remember over and over again. This will help you keep it in mind longer, especially for memorizing formulas * or facts.
◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it's a good idea to review the new things you learned that clay.
◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what's right and what's wrong, and it will lead to the right answer.
◆Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone's memory gets better if they use it often enough.
All of the suggestions are helpful. If you follow them, you are certain to improve your memory.

阅读理解 There have been many great inventions that have changed the way we live. the first great invention was one that is still very important today - the wheel. This made it easier to carry heavy things and to travel long distances. For hundreds of years after that, there were few inventions that had as much effect as the wheel did. In the second half of the 19th century, many great inventions were made, among them were the camera, the light and the radio. These are all a big part of our lives today. In the first half of the 20th century, we saw more great inventions. For example, the helicopter in 1909, movies with sound in 1926, the computer in 1928, and jet planes in 1930. This was also a time when a new material was first made. Nylon was made in 1935. It changed the kinds of clothes people wore. By this time, most people had a very good life. People had a desire to explore the world again. People knew a lot about the earth, but they didn't know much about the universe. They began looking for ways to go into space. Russia made the first step. Then the United States took the second step. Since then other countries, including China and Japan have done so too. In 1969, man took his biggest step from the earth. Two Americans walked on the moon. This is certainly just the beginning, too. New inventions will some day allow us to do things we have never yet dreamed of.

Sharks (鲨鱼) are the most frightening animals in the sea. Sometimes we can see sharks swimming in the sea around Hong Kong. People put nets around some beaches to protect swimmers. When there is a "shark's flag", people must stay on the beach. It will be too late if a shark can swim sixty kilometers an hour to you.

There are 30 kinds of sharks and 25 kinds of them are dangerous. The whale sharks are very big. They can grow to 18 meters long, but they are not dangerous to people. The jaws (大白鲨) and the tiger sharks are the most dangerous kinds of sharks.

Do you know all sharks must keep swimming, or they will go down? All sharks can feel everything that happens around them. We must keep calm and don't make any noise when a shark is swimming near you.

If a shark loses a tooth, a new one will grow out very quickly. So sharks always have many sharp teeth.
