The snow on the bottom pressed (挤压) together, it became ice. The ice was very wide and thick. It began to move down the mountain. It was like a river of ice. It was a glacier(冰河). Sometimes the glacier moved only a few inches(英寸) each day. As it moved, it took rocks and dirt with it. It changed the land. In some places, it left hills. In some places, when the glacier melted, it made rivers and lakes. A million years ago, there were many big glaciers. Glaciers covered many parts of the world. The glaciers changed the land. Glaciers are still at work today. A glacier in the north of Canada is cutting a new path down the side of a mountain. This glacier will change the land, too. 1．The snow fell on the mountain and ________. A．became snowman B．melted C．turned to rain D．became ice 2．When the glacier melted, it made _______ .

The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the earth again. It is a cycle that happens the whole year and is most active from March to June in China. In this article, we will learn about the water cycle and discuss its importance for Earth. The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow. The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water. Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty. 5．Which season has the most active water cycle in China. A．Spring B．Summer C．Autumn D．Winter 6．Which is the right order of the water cycle according to the passage? a. Water returns to the ground.            b. Rain or snow falls down. c. Water vapour rises up.                    d. Clouds are formed in the sky. A．c-b-d-a B．c-d-b-a C．d-c-b-a D．d-b-c-a 7．Why is the water cycle is important? A．Because it brings people warm weather. B．Because it cleans the air and the ground. C．Because it makes the climate healthy. D．Because it shows the beauty of nature. 8．Which shows the structure of the passage? A． B． C． D． 阅读下面短文，从短文后所给的选项中选出能填入短文空白处的最佳选项，使短文通顺连贯，其中有两项是多余选项。 The Chinese TV show To the Wonder makes more people know about Altay. The show is based on Li Juan’s book My Altay.

Your friend, Li Hua 答案： Dear Li Hua, I am very excited to receive your e-mail. I am interested in your questions. There are many rivers in our city. Ming Jiang River is one of the longest rivers. But the water in the river isn’t as clean as before. This is because people cut the trees down a lot, and some factories pour polluted water into it.  As we know, trees can keep the water much cleaner. On March 12th, we often plant some trees on the hills. More and more trees are growing. Our government is trying to stop the factories pouring dirty water into it. I think the water is becoming cleaner and cleaner. Looking forward to meeting you soon. Yours, Li Ming   【课堂检测】 Ⅰ. 根据句意及汉语提示、首字母提示或音标写单词 1.In the ______ (白天), my family prefers cycling in the park instead of staying indoors. 2.The ___________ (项目) goal is to collect 500 old books for the village library by next month. 3.After the storm, we carefully stepped around the ___________ (淤泥) to keep our shoes clean. 4.When it rained suddenly, we took c___________ under the thick tree branches to stay dry. 5.During the school event, we greeted guests with "Hello, s___________ and m___________" to practice good manners. 6.The brave firefighters k___________ the spreading fire before it reached the nearby houses. 7.The team designed a model to clean ___________ (/'weɪstwɔː(r)/) and make it safe for small ponds.

The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the earth again. It is a cycle that happens the whole year and is most active from March to June in China. In this article, we will learn about the water cycle and discuss its importance for Earth. The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow. The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water. Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty. 5．Which season has the most active water cycle in China. A．Spring B．Summer C．Autumn D．Winter 6．Which is the right order of the water cycle according to the passage? a. Water returns to the ground.            b. Rain or snow falls down. c. Water vapour rises up.                    d. Clouds are formed in the sky. A．c-b-d-a B．c-d-b-a C．d-c-b-a D．d-b-c-a 7．Why is the water cycle is important? A．Because it brings people warm weather. B．Because it cleans the air and the ground. C．Because it makes the climate healthy. D．Because it shows the beauty of nature. 8．Which shows the structure of the passage? A． B． C． D． 阅读下面短文，从短文后所给的选项中选出能填入短文空白处的最佳选项，使短文通顺连贯，其中有两项是多余选项。 The Chinese TV show To the Wonder makes more people know about Altay. The show is based on Li Juan’s book My Altay.
