　　What is colour? Why do some of the things around us look red, some green, others blue?

　　Colours are really made by reflected（反射）light. We see colours because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green it reflects most of the green light. If something reflects all light.it is white.

　　Some of the light is reflected and some is taken in and turned into heat. The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured clothes are warmer in the sun than light-coloured clothes.

　　In the fall, bears eat as much food as they can. So do chipmunks（花粟鼠）and some other animals. They all grow very fat.

　　Then these animals look for a warm place away from the cold. They sleep there all winter. They do not have to wake up to eat. They use their own fat for food.

　　At last, spring comes. The animals leave their winter beds. Their long sleep is over.

　　The sounds we hear on the earth are carried by the air. Since there is no air on the moon, people who get to the moon must talk to each other by radio. The dust（灰尘）in the earth's air, though very little, scatters（散射）he sunlight. This makes the earth's daytime sky blue and the shadows（阴影）are not completely dark. But on the moon, the sky is always black. You would be able to see stars in the daytime. Sunny places on the moon would be very, very bright. But the shadows would be almost black. The moon has no air or wind to carry the sun's heat. So it can get hot enough to boil（煮开）water in the places where the sun is shining straight down.

　　Killer bees started in Brazil（巴西）in 195A scientist in St. Paulo（圣保罗）wanted bees to make more honey（蜂蜜）.So he put forty-six African bees with some Brazilian bees. The bees bred（繁殖）and made a new kind of bees. But the new bees were a mistake. They didn't want to make more honey. They wanted to attack. Then, by accident（偶然的）, twenty-six African bees escaped and bred with the Brazilian bees outside.

　　Scientists could not control（控制）the problem. The bees increased fast. They went from Brazil to Venezuela（委内瑞拉）. Then they went to Central America. Now they are in North America. They travel about 390 miles a year. Each group of bees grows four times a year. This means one million new groups every five years.

　　Why are people afraid of killer bees? People are afraid for two reasons. First, the bees sting（叮）many more times than usual bees. Killer bees can sting sixty times a minute nonstop（中途不停地）for two hours. Second, killer bees attack in groups. Four hundred bee stings can kill a person.

　　Already several hundred people are dead. Now killer bees are in Texas（德克萨斯）. In a few years they will reach all over the United States. People can do nothing but wait.

One day in the fields my father takes off his coat and puts it on the ground under a big tree. Curly stands there and watches him. My father says,“Watch my coat,Curly.”

　　Curly sits down on the coat. In the afternoon my father forgets all about his coat and goes home without it. Later in the evening I miss my dog. So I look for him everywhere, calling,“Curly,Curly!”But Curly does not come. Later my father wants something in his pocket. Then he remembers where his coat is. He goes back to the big tree.

　　Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and animals. Man gets his food by eating plants and animals, too. So animals and man need plants in order to live. This is why there are so many plants around us.

　　There are two kinds of plants: flowering plants and non-flowering plants. Almost all the trees around us are flowering plants. You can know some trees from their flowers and fruits. Non-flowering plants do not grow flowers. You can not see many non-flowering plants around you.

　　If you look carefully at the plants around us, you will find that there are many kinds of plants. Some plants are large and some are small. Most of them are green. Thanks to the plants around us we can live on the earth.

(5) The best title（标题）for this passage is_______.

[　　]

　　Forests are large pieces of land covered with big trees. They are found all over the world, especially in places where there is enough sunshine and much rainfall. Many kinds of materials（材料）come from forests. To build a house, we need wood for doors and windows. Beautiful chairs and tables are also made of wood.

　　Teak（柚木）wood is very useful for ship-building. It is used for all parts of a ship where wood and metal come in contact（接触）, for it has a kind of oil to keep metal away from rust（铁锈）. It can also stop the attack of white ants and other insects. For this, teak wood is an important railway building material.

　　Forests are no less important than useful. They are the home of wild animals. Without them, those animals would run among the places where we live and work. There would be no peace for man.

　　Forests are helpful to weather, too. When it is very hot, they can be a good place for people to stay away from the sun. In winter, they can keep us from the cold. Forests can also stop the land from being washed away by heavy rain for the trees hold the soil together. So it would be foolish to cut down trees freely.
