Summer sees the mountains turn green with growing rice. During autumn, these same mountains are gold, and in winter they are covered with white snow. These are the colours of the Longji Rice Terraces (龙脊梯田). These terraces were built by the local Zhuang and Yao people in Guangxi. Work on the terraces took them hundreds of years from the Yuan Dynasty to the early Qing Dynasty. Reaching as far as the eye can see, these terraces cover tall mountains, often from the bottom to the very top. So why did these people go to so much trouble to turn the mountains into terraces? Firstly, there are few large, flat (平坦的) areas of land here. Building the terraces meant that they could increase more fields to grow rice. Secondly, the flat terraces catch the rainwater and stop the soil from being washed away. People have worked in harmony (和谐) with nature to make these terraces. The terraces are cleverly shaped, with hundreds of connected waterways. During the rainy season, waterways move the rainwater down the mountains and into the terraces. The sun heats the water and turns it into vapour (蒸汽). This forms clouds and then rain falls down onto the mountain terraces once again. Although modern technology could help produce more crops, these terraces still mean a lot to the local people. People continue to use ancient farming methods to keep the terraces, because these are their valuable traditions. Today, the Longji Rice Terraces receive high praise (赞扬), and thousands of visitors come to enjoy this great wonder created by people and nature working together. ( )1.How does the writer introduce the Longji Rice Terraces in Paragraph 1? A．By telling stories. B．By describing sights. C．By showing cultures. D．By making interviews. ( )2.What is Paragraph 4 mainly about? A．Why the farmers use the waterways to grow rice. B．Why the farmers turn the mountains into terraces. C．How people make full use of water cycle in the terraces. D．How the local people protect crops in the rainy season. ( )3.Why do the local people still keep their ancient farming ways? A．To value their traditions. B．To produce more crops. C．To share their experience. D．To satisfy more visitors. ( )4.Which of the following is NOT true? A．Longji Rice Terraces had a history of 100 years. B．Terraces can be seen in mountainous areas in Guangxi. C．Local people use a clever way to work together with nature. D．Longji Rice Terraces is also a tourist attraction nowadays. ( )5.What's the writer's purpose in writing the text? A．To introduce the history of the terraces. B．To advise people to build more terraces. C．To list the ways of improving technology. D．To praise the cleverness of the local people. Passage 2 How many seasons are there in your city in a year? Do you know how many seasons there are near the North Pole(北极)? Only two: winter and summer. In winter, nights are long. For more than two months, you can't see the sun, even at noon. In summer, days are long. For more than two months, the sun never goes down and there is no night at all. The temperature is very low near the North Pole. In summer the temperature is below 0℃， such as －3℃， so people there have to wear warm clothes all year round. They make their clothes from the fur (皮毛) of animals, such as coats, and hats. Life near the North Pole is very different. Because of the cold weather and the long time of darkness, plants cannot grow there. Such weather is also unfriendly for most animals. And people there have to build their houses with fur, earth, stone or snow. You may think that snow houses must be cold. In fact, they are very warm inside and safe. When people go out to catch or kill animals, they live in tents—something we can sleep in. When they move, they take their tents with them. ( )1.Which two seasons are NOT near the North Pole? A．Spring or summer. B．Spring or autumn. C．Summer or winter. D．Summer or autumn. ( )2.When do people near the North Pole need warm clothes? A．Only in winter. B．Just in summer. C．Only when it is －3℃. D．All year round. ( )3.What can we know about the summer near the North Pole? A．The night is very long. B．The sun never sets for over two months. C．The temperature is above 0℃. D．People don't need warm clothes. ( )4.What may people near the North Pole do? ①Kill animals for fur. ②Grow plants for food. ③See many kinds of animals. ④Live in snow houses. ⑤Sleep in tents in the snow. A．③④⑤ B．②③④ C．①④⑤ D．①②⑤ ( )5.Where can you read this article? A．In a travel guide. B．In a storybook. C．In a geography magazine. D．In a science poster. Passage 3 Rainforests cover six percent of the Earth's surface. There are rainforests in many parts of the world, but the biggest forests are in South America, Africa and Southeast Asia. There aren't any rainforests in Europe or North America. About 75 percent of animals live in rainforests. There are many beautiful birds, insects and so on. Many of them live in the trees, over 30 metres from the ground. There are also thousands of different plants. Lots of them are tall trees! It is always hot in the rainforests and the ground is always wet. It is also very dark there. The rainforests are very important for us. We need them! The trees and other plants in the forest help make the air clean. They also help control the weather. They give us wood, rubber, fruits and many of our medicines. Unfortunately, in many places, the rainforests are in danger. For example, many years ago there was a large rainforest in Java, but now there is nothing. The same thing happens now in many other parts of the world. We can never imagine a world without rainforests. If rainforests disappeared from the Earth, we wouldn't find any trees, flowers or fruits. What's more, we wouldn't get clean air, and we wouldn't find any animals. The worst result would be that we wouldn't find any humans. It's time to take action to save rainforests. ( )1.Where can we find the biggest forests? A．In Asia. B．In Africa. C．In America. D．In Europe. ( )2.What does the underlined word “them” in Paragraph 2 refer to? A．The animals. B．The birds. C．The insects. D．The plants. ( )3.Which of the following about rainforests is TRUE? A．Thousands of different plants in rainforests are tall trees. B．It is cool in the rainforests and the ground is always wet. C．The rainforests provide us with clean air and good weather. D．Rainforests in many parts of the world are disappearing. ( )4.What may the writer continue to talk about in the following paragraph? A．Reasons for rainforests in danger. B．Ways to protect rainforests. C．Actions to plant more tall trees. D．Results for losing rainforests. ( )5.Where can we probably find the passage? A．In a travel guide. B．In a storybook. C．In a nature magazine. D．In a dictionary. Passage 4 Some crops are grown in places where there isn't enough rain for plants to grow. For example, crops grow in deserts. How is this possible? It's 1 irrigation (灌溉). Irrigation is when extra water is given to plants 2 them grow. Most of 3 water used on farms is for irrigation. Animals also need water, but they use much less. But irrigation 4 waste a lot of water. The kind of irrigation shown in the picture 5 the most wasteful. The water is sent into the air in small 6 ， so much of it doesn't reach the plants. It either 7 into the air or runs off the fields. Irrigation water can also cause 8 problems. It can carry chemicals that are used on crops. These chemicals can go 9 into the earth and pollute rivers or lakes. Sometimes, the water has salt in it. This can make the soil 10 salty for plants to grow.

Grandpa was a tea farmer, and his 1 was famous for its sweet taste. But this year, something strange happened—the tea plants were not growing well. The leaves were 2 ， and the soil looked dry. One night, Xiaolong heard a soft voice coming from the forest. He followed the 3 and found an old tree. The tree said, “I am the Magic Tea Tree. The forest is sick because people are cutting down too many trees. If you help the forest, I will help your tea 4 .” The next morning, Xiaolong told Grandpa about the tree. Together, they decided to 5 more trees around the tea fields. Xiaolong worked hard, digging 6 and planting young trees. He even asked his friends to help. 7 ， the forest began to recover. Birds returned, and the soil became 8 again. One day, Xiaolong noticed something amazing—the tea plants were growing bigger and greener than ever! The Magic Tea Tree had kept its promise. Grandpa's tea tasted sweeter than before, and everyone in the village was 9 . Xiaolong learned an important lesson: taking care of nature brings good things in return. From that day on, he promised to 10 the forest and teach others to do the same. The Magic Tea Tree became his secret, and the forest thrived for years to come.

The Japanese government (政府) said it was 1 to do this. 2 everyone worries about what will happen if the wastewater enters the sea. It might be dangerous. The wastewater will first 3 the sea around Japan and its neighbour 4 ， like China and South Korea. It will go to most of the Pacific Ocean in 57 days. And in three years, it will 5 the US and Canada. The sea covers 71% of Earth's surface. So the wastewater will go to most parts of the world. The radiation (辐射) could stay in the sea for thousands of years! Is nuclear power a(n) 6 thing? This answer is “No”. Nuclear power can 7 us with electricity (电) and heat. It also powers trains, planes and aircraft carriers. However, radiation is bad for humans, sea animals and plants. For example, it can cause (引起) some fish to 8 or even die. If you eat these fish, radiation will enter your body, too. Can we eat safe and healthy 9 in the future? Maybe people will 10 eat it because Japan dumps nuclear wastewater into the sea.
