How airplanes fly?

People {#blank#}1{#/blank#} (try) for a long time before they invented a {#blank#}2{#/blank#} (success) "flying machine". Now there {#blank#}3{#/blank#} (be) so many {#blank#}4{#/blank#} (plane) in the sky.

    An airplane {#blank#}5{#/blank#} (fly) because of the upward force(力量) of {#blank#}6{#/blank#} (move) air against its wings(翼). To get that moving air, it needs something {#blank#}7{#/blank#} (push) it forward—like a motor-driven propeller(螺旋桨) or a jet engine(喷气发动机). You can fly a kite if there  {#blank#}8{#/blank#} (be) enough wind to hold it up. An airplane is like a kite with such force!

    Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. It's a great pity. It is reported that about 170 kinds in the United States alone are considered in danger.

    Therefore, we must take care of the animals around us. Once they are gone, they will never come back again. Animals are more than just beautiful or interesting. They are more than a source of food. Every animal has its importance to nature. Destroying one kind of animal can cause many problems. For example, when farmers kill large numbers of hawks(鹰), their eat rats and mice, with fewer or no hawks to keep down their numbers, rats and mice multiply quickly.

    Luckily, many people have realized this and have begun to do something to protect animals. Some groups put on performances to make people know the importance of protecting animals. Some raise money to help set up more zoos to keep them safe. Some try to get the government to pass laws on protecting the animals in danger. As a result, the number of these animals is growing.

    The first people who drank tea were the Chinese. The bush grew wild all over the south of China. Chinese people liked the taste, and found that the drink could refresh (使恢复精力)them. The new drink reached England in 1657. It was sold at one of the coffee houses. Only the very rich people could afford (买得起) to drink.

    Now, people drink tea all around the world. But tea does not mean the same thing to everyone. In different countries people have very different ideas about drinking tea. In China people always have tea together with their friends. They may drink tea at any time of the day. They only put tea leaves in their cups. They prefer the tea with nothing else in it. In the USA people drink tea at breakfast or after meals. They usually use tea bags to make their tea. Making tea with bags is faster and easier than making it with tea leaves in teapots.

    Today, when we think of Western tea culture, we often think of the English, afternoon tea and beautiful china tea cups. It's believed that an English lady, Anna, first introduced the idea of afternoon tea. She invited some friends to join her for an afternoon meal between four and five o'clock. This meal included cakes, sandwiches and tea. In order to make this afternoon meal important, fine china cups and plates, and silver teapots, knives, forks and spoons were used. Soon, afternoon tea parties became popular social occasions (社交活动). Today, afternoon tea parties continue to play an important part in the social life in modern Britain.

Customs on Eating

    Food in China and western countries is different. China has about five thousand years' history. Chinese people may spend half of their time on food. They choose food very carefully. They only use fresh materials to make food. For example, they only eat fresh fish. Chinese people have a lot of ideas for cooking. They can cook a chicken in over ten ways. So Chinese food is very popular around the world. Western countries, like England or America, don't have fresh food because they buy their food from supermarkets. -They only sell stored materials. Western people also prefer fast food like hamburgers and chips. They are unhealthy for people's body. Western people are very good at making desserts and chocolates. They can make very good cakes and chocolates. These food are very sweet and can make people become fat quickly.

    In China, when people invite others for a meal, they would pay for the meal, but it's not the same way in western countries. In western countries, people will think you only invite them but don't need to pay for them. They won't be happy if you pay for them.

Another difference in eating is that: Chinese people use chopsticks but western people use knives and forks.

    Chinese people only have three meals in a day. But western people may have more. They usually have afternoon tea when they would have fruit or cakes with cheese.
