Some are red, green, yellow, or black. There have been snowflakes of almost every shape. Think how it would seem to have these coming down all around you. Wouldn’t they look pretty?Black snow came down in France one year. Another year gray snow fell in Japan. It was found that such snow was mixed with ashes. This made it seem dark. Red snow has come down in other countries. When this happened, it was mixed with red dust. That’s why it looked different. Most snow looks white, but it is really the color of ice. It is ice that comes from snow clouds. Each snowflake begins with a small drop of water. More water forms around this drop. The way the water freezes gives the snowflake its shape.No two snowflakes are ever just the same size or shape. All start out flat and have six sides. Some snowflakes are broken when they hit the ground. Others melt as they fall. When air is cold and dry, the falling snowflakes are small and hard. If the air is wet and warmer, the snowflakes are big and soft.Would you be surprised to see snowflakes as big as your head falling from the sky? It happened once in our country. It could occur again.1. Snowflakes are ________according to the writer.A. white starsB. whiteC. of all shapesD. pretty2. Snowflakes come in different shapes as ________ different.A. the ways they form areB. the speed they fall isC. the weather isD. the ways the water freezes are3. According to the passage, if the snowflakes are hard and small, the weather should be ________.A. cold and wetB. dry and wetC. wet and warmD. cold and dry4. We can infer from the last paragraph that very large snowflakes _________.A. occur regularlyB. will occur regularlyC. occur once a yearD. doesn’t often occur5. To snowflakes, which of the following statements is true?A. Color snowflakes look so because they are mixed with dust of different colors.B. Most snowflakes look white, and it is the color of ice.C. Probably there are two snowflakes of the same size and shape.D. Most snowflakes are made from water and dust.82. A hobby is something you do just for fun. It could be painting pictures, watching birds, or reading. Some people collect, or save things. These things could be new. But they might be old.Many beautiful things were made long ago.Where do people get the things that they collect? At the beach many people pick up pretty shells to save. They find them near the sea. Some people pick up things from the street. They find things in the garbage. Others save things they get from their families or friends. Still others buy things to collect.Why do people collect things? First it can be fun. People really like the things they save. Also, you and a friend may collect the same thing. Then it’s some thing you can do together. But some people like to do it alone. To them, a hobby is something you do by yourself.People also learn from their hobbies. You might have many pictures of kings. If you wanted to know more about them, you could go to the library and get a book. Then you could read about them. You would find out such things as when and where they lived.Saving things gives people something to do. Both children and older people like to have hobbies. Some people no longer work. So they collect things to keep busy. Hobbies fill many people’s days with hours of fun.1. A hobby is not something that .A. you enjoy doingB. you do in your spare timeC. you can learn something fromD. you do to make money2. A hobby can hardly be .A. creating thingsB. collecting thingsC. saving thingsD. selling things3.

Whoever you are, you can find your hobbies.B. People can’t collect things until they no longer work.C. People of all age can enjoy their hobbies.D. People can have a lot of fun through their hobbies.83. In the night sky you might see a big white ball. This is the moon. The moon moves around the earth. It does this one time about every 291/2 days. It is smaller than the stars. But it looks bigger. That’s because it is closer to us than the stars.Sometimes the moon looks like a ball of light. Other times it looks only part of a ball. But it is really always the same. The moon’s light comes from the sun. Sometimes one part is lighted. Other times another part is lighted. We see only the part of the moon that is lighted.The moon has no air, no wind, and no water. So nothing can live there. There are no plants or animals. It is made up mostly of rock. There are big holes all over the moon. Sometimes you can see dark places on the moon. It is really these holes that you are seeing.Let’s say you were standing on the moon and y ou looked up. The sky would be black. It always looks like night. And the stars in it are always out. In the day the rocks on the moon get very hot. At night they are colder than any place on the earth.People have always liked to look at the moon. In it they have seen many things. Some think they see people. Others see animals. One person might see a frog or a cat. Another might see a rabbit. Look up at the moon tonight. What do you see?1. According to the passage we know that the moon .A. is bigger than the stars, but looks smallerB. looks smaller because it is closer to us than the starsC. is smaller than the stars, but looks biggerD. looks bigger because it is farther to us than the stars2. Which of the following statements is NOT true according to the passage .A. The light from the sun sometimes lights only one part of the moon.B. People could see dark holes al over the moon.C. Nothing could live on the noon except animals because it is made up of rock.D. No life could be seen on the moon without air and water on it.3. From the passage we can infer that .A. the difference between day temperature and night temperature on the moon is very bigB. people could not stand on the moon because it is very hot in the dayC. people could not stand on the moon because it is too cold at nightD. it’s impossible for people to live on the moon because there is no food there4. The author implies that the reason why people like to look at the moon is that .A. they believe there are really people on the moonB. they think some animals are living on the moonC. they care for the frogs, cats and rabbits on the moonD. the moon can give them many imaginations5. The purpose of the writer in writing this passage is to .A. tell us something about the moonB. require us to distinguish the moon and the starsC. emphasize the importance of the moonD. state the relationship between people and the moon84. During one summer not long ago, Americans in the Southwest were without rain for many days. The sun burned up crops. Animals went hungry on the dry land. At last, clouds appeared in the sky and sent down rain.How do such clouds form? The sun, the earth, and the air all play a part. The changes that take place before clouds can form do not always happen quickly. First, the earth is heated by the sun. This causes tiny drops of water in oceans and rivers to rise and mix with air. As the wet air rises higher, it cools off, making clouds.What causes these clouds to become rain? The tiny drops of water inside the clouds become。
