U2 - How? Why?: Lesson 2 - Why Do People Laugh?Do you laugh every day? Most people do. Scientists say that people laugh about 17 times a day. That is a lot of laughter.In India, there are hundreds of laughter clubs. The people in these clubs get together every morning. First they stretch their hands above their heads. Then they pretend to laugh. Soon everyone is laughing naturally.People say they feel good after laughing together.Scientists believe that laughter is good for you. Why? For one thing, laughter is good exercise. When you laugh, you exercise many muscles in your body. Scientists say that one hundred laughs equals ten minutes of running. When you laugh, you also breathe deeply. This helps you relax. That's good for you, too.Why do we laugh? That is a hard question to answer. We know that people laugh more often in a group. They don't laugh very often when they are alone. Many scientists believe that we use laughter to connect to other people. Laughter helps us feel part of a group.In English, people say that laughter is the best medicine. Some think that laughter helps sick people get well. Do you think so, too?

U1-Animal : Lesson 3 - The Polar BearThe polar bear is a very big white bear. We call it the polar bear because it lives inside the Arctic Circle near the North Pole. There are no polar bears at the South Pole.The polar bear lives in the snow and ice. At the North Pole, there is only snow, ice, and water. There is not any land. People cannot see the polar bear in the snow very well because its coat is yellow-white. It has a very warm coat because the weather is cold north of the Arctic Circle.This bear is three meters long, and it weighs 450 kilos (kilograms). It can stand up on its back legs because it has very wide feet. It can use its front legs like arms. The polar bear can swim very well. It can swim 120 kilometers out into the water. It catches fish and sea animals for food. It goes into the sea when it is afraid.Some people want to kill the polar bear for its beautiful white coat. The governments of the United States and Russia say that no one can kill polar bears now. They do not want all of these beautiful animals to die.(200 words)中学生百科英语1-第一单元Animal 1。

中学生百科英语1-U4-L1-Music and Behavior
Unit 4 MusicLesson 1 Music and BehaviorWhere did you go yesterday? Did you hear music at any of those places? There is a good chance that you did. Today most stores and restaurants play music. You might even hear music in an office or on a farm.Scientists believe that music affects the way people behave. According to some scientists, the sound of western classical music (Mozart and Bach) makes people feel richer. When a restaurant plays classical music, people spend more money on food and drinks. When the restaurant plays modern music, people spend less money. With no background music, people spend even less.Scientists also believe that loud, fast music makes people eat faster. People actually chew their food faster when the music gets faster. Some restaurants play fast music during their busy hours. This gets people to eat faster and leave quickly. Restaurants can make more money this way.Some scientists think that music makes you think and learn better. They say that music helps students to be more alert. It is true that people learn better when they are relaxed. And listening to music can help you relax.The next time you hear music somewhere, be careful. It might change the way you behave.

中学生百科英语1-U3-L5 - The Coffee Plant
U3 - Plants: Lesson 5 - The Coffee PlantHow many cups of coffee did you drink yesterday? Where did the coffee come from? There is a good chance that your coffee came from one of these countries: Brazil, Colombia, Indonesia, Ivory Coast, or Ethiopia. These five countries produce most of the coffee in the world today. Brazil produces about half of the world's crop of coffee beans.The coffee plant is really a small tree with shiny leaves. A coffee plant grows for about three years before it produces any fruit. After that, it produces fruit for about 40 years. The coffee bean is the seed of the fruit.It's difficult to pick coffee beans. Machines can't do it well, so people pick most of the coffee beans by hand. Workers typically pick between 20 and 40 pounds of coffee beans a day.The old way to grow coffee plants is under large trees. The trees protect the coffee plant from the sun. The trees are also home to many kinds of birds. On many modern farms, however, farmers cut down the trees. They grow the coffee plants under the sun. Large farms can produce more coffee this way. Unfortunately, the coffee plants on these farms need more water and more fertilizer. And without the trees, the birds don't have a place to live. (216 words)中学生百科英语1-第三单元Plants第1页共1页。
中学生百科英语1-U3-L2 - The Water Hyacinth
U3 - Plants: Lesson 2 - The Water HyacinthThe water hyacint h grows in tropical countries. It has beautiful purple-blue flowers, but everybody hates it. Why?Millions and millions of these plants grow in rivers and lakes. Sometimes the plants become so thick that people can walk on them. People cannot travel in boats on the water, and they cannot fish in it. The plants stop the water from moving. Then the water carries diseases. Farmers cannot use the water on their land.Now scientists think that water hyacinths can be useful. The plants are really a free crop. No one has to take care of them. They just grow and grow and grow. What can farmers use them for?Some fish like to eat them. Farmers can grow these fish in the lakes and rivers.Workers can collect and cut the plants with machines. Then they can make fertilizer to make their crops grow better. They can also make feed for their farm animals.Maybe it will be possible to make methane gas (CH) for energy. (We burn gas from petroleum for energy. Methane gas can be made from plants.) Then poor tropical countries will not have to buy so much expensive petroleum. Maybe in the future people will love the water hyacinth instead of hating it. (209 words)中学生百科英语1-第三单元Plants第1页共1页。
