During Major Snow, the t 1 falls greatly, and there may be more snow. Farmers welcome the snow, because when fields are c 2 with snow, the snow acts like a blanket (毛毯) that traps warmth in the soil, so h 3 is less likely to be lost. In this way, crops are protected from cold frost. Even i 4   the snow melts, it can also provide enough water for the g 5 of some winter crops in spring. The s 6 season is also perfect for sports like skiing or skating. There are many such places for natural snow and ice in the n 7 part of China. For example, Heilongjiang and Jilin provinces often have heavy snow in November, leaving rivers and lakes f 8 , which makes ice sports common.

Have you heard of World Rainforest Day? It’s on June 22nd, and it’s like a big birthday party for the most amazing places on Earth—the rainforests. Rainforests cover just 6% of the Earth’s surface but are h 1 to over half of all the world’s plants and animals. Imagine walking t 2 a rainforest, hearing the calls of colorful birds, spotting playful monkeys swinging from tree to tree, and seeing giant trees that r 3 for the sky. These places are not only beautiful but also i 4 . They’re often called the “lungs of the Earth” because they suck in carbon dioxide and p 5 oxygen (氧气) that we all need to live. S 6 , these rainforests are in big trouble. Every day, huge areas of them are cut down for things like farming, logging, and building cities. If this c 7 , many amazing plants and animals will disappear. But don’t worry—we can be rainforest heroes. We can start by using less paper and choosing products that don’t hurt the rainforests. Also, s 8 the word to our friends and family about how awesome rainforests are helps a lot. On World Rainforest Day, there are cool things to do. Fun science projects about rainforests might be o 9 by schools, like making a mini rainforest in a jar. There are also tree- planting events. They are situations w 10 you can get your hands dirty and help grow new forests. So, mark June 22nd on your calendar.

And water levels in the huge Colorado River were d 1 rapidly. This was the beginning of a serious drought (干旱). Everyone began asking, “How long will it last?” Meko believed that he could find the answer in the trees. Meko is a tree-ring expert. He finds that these rings are nature’s r 2 of rainfall and climate change. Each year, a tree adds a new layer of wood. These layers look like a series of rings. During times of h 3 rainfall, a ring is wide. When there is a shortage of water, a ring is narrow. Meko and his team quickly started a new research project. Their g 4 was to find out how long previous droughts lasted. The team collected as many old wood samples as possible. They tested wood samples from 1,200 years ago u 5 the present. When they examined the rings, the news about rainfall in the past was not good. Meko’s research showed that the 20th century was an unusually wet time. Trees from this p 6 had wide, healthy rings. Rain was plentiful during that century. Millions of people moved to the region. Before that time, however, the rings showed that droughts happened on a regular basis (有规律地). In fact, drought was p 7 of the usual climate pattern. There were severe droughts in the 900s, the 1100s, and the late 1200s. Human history seems to s 8 Meko’s findings. The native Anasazi lived in this area for hundreds of years, starting around 500 AD．They were farmers and depended on water to grow their crops. H 9 , at the end of the 13th century, the Anasazi suddenly left the area. Experts think it was because there was no longer enough water to farm. Meko’s tree rings clearly show a serious drought at that time. How long will the current (当下的) drought l 10 ?

We learned a lot about different natural d 2 , such as earthquakes, typhoons and wildfires. The teacher explained the c 3 and effects of these events clearly. For example, a typhoon usually brings strong winds and heavy rain. It can blow down trees and d 4 houses. Then, we watched a video about a terrible earthquake. It happened so s 5 that many people got hurt. Later, we discussed how to keep s 6 during an earthquake. If we are indoors, we should hide u 7 a strong desk and hold on to it tightly. If we are outside, we should run to an open space as fast as p 8 . We cannot control the earth, but we can p 9 for the worst. It is highly necessary for us to remember these safety t 10 . Yours, Li Hua 根据首字母提示完成短文。 Have you ever been to Dongting Lake? It’s famous as “800-li Dongting Lake”. Dongting Lake is in the n 1 part of Hunan Province. It is normally about 2,800 square kilometres in s 2 . It is one of the five largest freshwater (淡水的) lakes in China. Every year thousands of t 3 from all over the world come to Yueyang in order to enjoy the beautiful scenery (景色) around Dongting Lake. With the development of society, p 4 Dongting Lake has become a hot topic. In fact, people of Yueyang are trying to improve the environment of the lake. On the one hand, the government set up East Dongting Lake National Nature Reserve in 1982. It p 5 a good place for birds and rare animals. East Dongting Lake National Nature Reserve is also h 6 to Yangtze finless porpoises and more than 200 rare milu deer, both under first-class protection in China. On the other hand, factories mustn’t put waste water into the lake. Now that it is cleaner, Dongting Lake is attracting large n 7 of birds. More than 280,000 waterbirds live t 8 the winter at Dongting Lake. Fishes are living in the clean water. It will be great fun if people take a b 9 tour on the lake, watch birds, listen to the waves, go f 10 and taste delicious fish dishes in the nature reserve. Nowadays, “green living” has become a hot topic around the world. It’s very important for us to protect the e 1 we live in. Here are some simple things we can do in our daily life. First, we should r 2 waste. We can use both sides of the paper to save trees. We can take cloth bags when we go shopping instead of using plastic ones. We should also say no to d 3 chopsticks and cups to cut down white pollution. Second, we should learn to s 4 waste into different groups. Recyclable things like waste paper, plastic bottles and glass can be sent to recycling centres. In this way, we can make full use of natural r 5 and reduce pollution at the same time. Third, we should save energy in our daily life. Remember to turn off the lights and taps when we don’t use them. We can take the bus or ride bikes instead of driving cars, which can help r 6 air pollution. Fourth, we should take a 7 to spread the idea of green living. We can tell our family and friends the importance of protecting the environment. We can also join in some volunteer activities, like picking up litter in the park or p 8 trees in the hills. Many people think protecting the environment is a big thing, but in fact, it’s j 9 something that everyone can do easily. Even a small action can make a big d 10 to our earth. Let’s start from now on! The Amazon Rainforest is the world’s b 1 rainforest. It covers 6 m 2 s 3 kilometres. It is in South America, covering countries like Brazil, Peru, and Colombia. You can find many kinds of l 4 plants and animals there. We must remember that nature is important to us. We need to measure the d 5 of lakes and the height of mountains to understand our world better. It is not c 6 to see such a large forest anywhere else. So it is a true natural w 7 . Everyone should take action to protect the natural environment so that animals and plants can s 8 safely. Let’s learn more about geography. Then we can explore this u 9 world and stand at the t 10 of it! 进阶拓展训练4篇 阅读下面短文，根据首字母提示补全单词，使短文完整、通顺。每空限填一词。 Major Snow, the 21st solar term of the year, marks the start of midwinter. During Major Snow, the t 1 falls greatly, and there may be more snow. Farmers welcome the snow, because when fields are c 2 with snow, the snow acts like a blanket (毛毯) that traps warmth in the soil, so h 3 is less likely to be lost. In this way, crops are protected from cold frost. Even i 4   the snow melts, it can also provide enough water for the g 5 of some winter crops in spring. The s 6 season is also perfect for sports like skiing or skating. There are many such places for natural snow and ice in the n 7 part of China. For example, Heilongjiang and Jilin provinces often have heavy snow in November, leaving rivers and lakes f 8 , which makes ice sports common. Though we have much interest in playing with snow, we should pay attention to respiratory (呼吸的) i 9 . When it’s Major Snow, it is much colder and drier, so people should drink more water. We can also drink hot soup with ginger (生姜) and Chinese dates (枣) to fight a 10   the cold. 根据短文内容及首字母提示，填写所缺单词。 Hey, everyone. Have you heard of World Rainforest Day? It’s on June 22nd, and it’s like a big birthday party for the most amazing places on Earth—the rainforests. Rainforests cover just 6% of the Earth’s surface but are h 1 to over half of all the world’s plants and animals. Imagine walking t 2 a rainforest, hearing the calls of colorful birds, spotting playful monkeys swinging from tree to tree, and seeing giant trees that r 3 for the sky. These places are not only beautiful but also i 4 . They’re often called the “lungs of the Earth” because they suck in carbon dioxide and p 5 oxygen (氧气) that we all need to live. S 6 , these rainforests are in big trouble. Every day, huge areas of them are cut down for things like farming, logging, and building cities. If this c 7 , many amazing plants and animals will disappear. But don’t worry—we can be rainforest heroes. We can start by using less paper and choosing products that don’t hurt the rainforests. Also, s 8 the word to our friends and family about how awesome rainforests are helps a lot. On World Rainforest Day, there are cool things to do. Fun science projects about rainforests might be o 9 by schools, like making a mini rainforest in a jar. There are also tree- planting events. They are situations w 10 you can get your hands dirty and help grow new forests. So, mark June 22nd on your calendar. Let’s join hands and show the world that we’re ready to protect these natural treasures. 根据短文内容及首字母提示，填写所缺单词，使短文意思完整，每空限填一词。 The natural world is filled with living things. Living things start out weak and small, and s 1 grow strong and big. You are a living thing. Flowers, grass and trees are living things, too. Bees, ants, dogs and cats—these are all living things. All living things need food and water to s 2 . From these basic needs, living things get the strength to grow. Think about y 3 . If you are hungry, you need to eat. You eat fruit, vegetables, meat and fish. They can p 4 you with energy. You drink water every time you feel thirsty. Now think about a tree. W 5 a tree is hungry, it gets food from the soil (土壤). Trees drink water, too. We are different in some ways, but all living things are connected. We are all on the same planet, and we depend on each other. If we pollute the rivers and oceans, fish may get s 6 or even die. Some birds l 7 on fish. If the birds eat these fish, they may die. This can have t 8 effects on ecosystems. Nature is a b 9 between all the living things on the planet. If one species (物种) dies off, then another species may die off, followed by another, and another... We must a 10 now. We should respect the earth and protect all the living things on it. The Answer Is In the Trees Dave Meko, a scientist at the University of Arizona, noticed that from 1999 to the following years it became drier and drier. And water levels in the huge Colorado River were d 1 rapidly. This was the beginning of a serious drought (干旱). Everyone began asking, “How long will it last?” Meko believed that he could find the answer in the trees. Meko is a tree-ring expert. He finds that these rings are nature’s r 2 of rainfall and climate change. Each year, a tree adds a new layer of wood. These layers look like a series of rings. During times of h 3 rainfall, a ring is wide. When there is a shortage of water, a ring is narrow. Meko and his team quickly started a new research project. Their g 4 was to find out how long previous droughts lasted. The team collected as many old wood samples as possible. They tested wood samples from 1,200 years ago u 5 the present. When they examined the rings, the news about rainfall in the past was not good. Meko’s research showed that the 20th century was an unusually wet time. Trees from this p 6 had wide, healthy rings. Rain was plentiful during that century. Millions of people moved to the region. Before that time, however, the rings showed that droughts happened on a regular basis (有规律地). In fact, drought was p 7 of the usual climate pattern. There were severe droughts in the 900s, the 1100s, and the late 1200s. Human history seems to s 8 Meko’s findings. The native Anasazi lived in this area for hundreds of years, starting around 500 AD．They were farmers and depended on water to grow their crops. H 9 , at the end of the 13th century, the Anasazi suddenly left the area. Experts think it was because there was no longer enough water to farm. Meko’s tree rings clearly show a serious drought at that time. How long will the current (当下的) drought l 10 ? Using nature’s clues from the past, experts predict that this drought may continue for another 50 years. 能力综合实践4篇 The giant panda is one of the most handsome and beloved animals in the world, known for its black-and-white fur and gentle nature. In the past, they lived peacefully in the thick bamboo forests of southwest China, wandering without a care in the world and feeding on fresh bamboo shoots. However, as human activities expanded rapidly, their natural habitats shrank sharply, and they were f 1 to move to smaller, isolated areas to search for enough food. Sadly, some greedy people once tried to s 2 pandas dead for their valuable fur, completely ignoring their true v 3 as a national treasure. Today, the situation has changed greatly.

Thanks to these continuous efforts, great p 7 has been made in panda protection. The wild panda population has slowly i 8 , and they are no longer classified as an “endangered” species. This reminds us that protecting wildlife is protecting our own home. Kanas Lake in Xinjiang Kanas Lake is a very b 1 place in Xinjiang, in the north-west of China.
