An Hour of Darkness to Support the Planet
Last year, cities around the world turned off their lights on Saturday for Earth Hour, focusing on the relationship between the destruction (摧毁) of nature and increasing outbreaks of diseases such as COVID-19.
In London, the Houses of Parliament, London Eye Ferris wheel, Shard skyscraper were among the landmarks (地标) that turned off the lights. The Eiffel Tower in Paris also went dark. The wonderful metal tower has been shut to the public since October 30 because of the COVID-19 pandemic (流行病).
Asia began the event after night fell with big cities from Singapore to China going dark, as did landmarks including the Sydney Opera House. The Brandenburg Gate in Berlin and the Kremlin in Moscow also joined the plan that calls for action on climate change and the environment every year. After Europe, Earth Hour moves west to the Americas with the Empire State Building in New York, the Obelisk of Buenos Aires and the Museum of Tomorrow in Rio de Janeiro among places making the lights dark.
Organizers said they want to highlight the relationship between the destruction of the natural world and the increasing outbreaks of diseases such as COVID-19. Scientists believe human activities such as the damage of forests and animals' homes, and climate change are causing this increase. They warn more pandemics could break out if nothing is done.
“Fewer fish in the ocean and rivers, disappearing forests or the wider loss of biodiversity (生物多样性), all these show that nature is in free fall,” said Marco Lambertini, director-general of the World Wide Fund for Nature, which organizes Earth Hour. “And this is because of the way we live our lives and run our economies (经济). Protecting nature is our duty.”
1．What’s the focus of this year’s Earth Hour event
A．The protection of forests and people’s health.
B．The relationship between nature and diseases.
C．The prevention of the use of lights in the world.
D．The relationship between human activities and forests.
2．Why was the Eiffel Tower closed to the public
A．Because the COVID-19 broke out. B．Because there was a flood in the area.
C．Because the weather there was terrible. D．Because there were too many tourists.
3．Marco Lambertini means that _______.
A．it is human that harms the nature and should protect it
B．nature is falling slowly because of the human society
C．the biodiversity is in a loss because of disappearing forests
D．nature is increasing because we are protecting it
In the 13th century, Marco Polo discovered money made of paper in China. The West didn’t have such kind of money until the 15th century. However, the Chinese began to use it in the 7th century.
Paper was invented by a Chinese man called Cai Lun almost 2,000 years ago. But it was not made in Europe until the year 1100. A German discovered that he could make the best paper from trees 400 years later. After that, countries rich in forests, such as Canada, America and Finland became the most important ones in paper making.
Paper is quite useful in our life. It is the carrier of writing and printing. Painters use it to describe the beauty of the world, writers use it to tell the warmth of the world, and educators use it to spread knowledge. But do you know that paper can be used for keeping warm In Finland, the farmers wear paper boots (靴子) to keep their feet warm in the snow.
However, we have to understand that paper still comes from trees now. Every day people throw away about 2,800 tons of paper in our city. If we keep on wasting so much paper, there will not be any trees left on the earth some day in the near future.
So we must start saving paper right now before it is too late. We can use both sides of every piece of paper and make useful things out of used paper. When shopping, we can use fewer paper bags and reuse them if we have some.
4．When did the Chinese begin to use paper money
A．In the 13th century. B．In the 14th century.
C．In the 15th century. D．In the 7th century.
5．Canada became an important country in paper making because ________.
A．it was a large country B．it was a rich country
C．it had a lot of forests D．it discovered the best paper
6．The third paragraph mainly tells us ________.
A．where paper was invented B．what paper is used for
C．when Finland invented paper D．how we can save paper
7．Why does the writer write the last two paragraphs
A．To remind us of saving paper.
B．To share the use of paper bags.
C．To introduce the ways of inventing paper.
D．To tell us to plant more trees.

Gordon Hempton is an ecologist (生态学家). He has spent more than 40 years studying natural sounds and saving quiet. Why save quiet
Today, man-made noise seems to be everywhere. It keeps us away from natural sounds and is bad for our health. However, quiet helps us a lot. Like nature, it helps us find peace in our minds. But the number of naturally quiet places is going down quickly.
Hempton became interested in natural sounds many years ago. One day, he was driving and got tired. So he stopped his car and found a place to rest. Then the rain poured down, and Hempton stayed and listened. “I stayed away from all man-made noise then and only heard the rain and animals making sounds,” he said. “I was surprised.”
In the following years, Hempton tried to find naturally quiet places and record natural sounds. In 2005, he found a dream place in a forest park. He did a lot to keep the quiet there. However, in 2018, man-made noise finally broke it. This made him realize that man-made noise breaks not only the quiet of this place but also that of the world. So, he started the Quiet Parks International (QPI) in the same year. He wanted more people to take action to save quiet.
Now, Hempton and his team are busy saving quiet. Thanks to them, we can hear some of the world’s finest recordings of natural sounds and keep some best quiet places.
13．What is Paragraph 2 mainly about
A．Ways to save quiet. B．Reasons for saving quiet. C．Where Hempton saves quiet.
14．Hempton became interested in natural sounds after ________.
A．meeting an ecologist in a forest park
B．listening to a recording of natural sounds
C．listening to the sounds of the rain and animals
15．Hempton started QPI ________.
A．in 2018 B．in a park C．to remember his dream place
16．The writer wrote the passage mainly to ________.
A．ask us to make less noise B．advise us to be an ecologist C．tell us the story of an ecologist
Trees are useful to men in three important ways: They provide them with wood and other products , they give them shade , and they help to prevent drought and floods.
Unfortunately, in many parts of the world, men have not realized that trees are the most important. In their eagerness (渴望) to make money from trees, some people have cut trees down in large numbers, only to find that without them they have lost the best friends they had. And besides, they are usually too careless to plant and look after new trees, so the forests slowly disappear.
This doesn’t only mean that men will have fewer trees. The results are even more serious: where there are trees, their roots break up soil—allowing the rain to sink in and also bind (绑定) the soil, thus preventing it from being washed away easily, but where there are no trees, the rain falls and carries away the rich top-soil. When all the top-soil is gone, nothing remains but worthless desert.
17．The most important service of trees to men is ________.
A．they give people wood and other products
B．they give people shade and cool
C．they help people prevent drought and floods
D．they help people make money
18．Land becomes desert after all trees cut down, because ________.
A．there is too much rain
B．there are no more trees to keep the rich top-soil from being carried away by floods
C．there is a strong wind
D．roots of trees break up the soil
19．What does the underlined word “roots” mean in Chinese
A．树干 B．树根 C．树皮 D．树种子
20．People cut down a large number of trees because ________.
A．they wanted to get wood from them
B．they wanted to get money from them
C．they didn’t realize the importance of them
D．all the above
21．Which of the following is NOT true
A．Tree roots can make the top-soil rich and the ground hard.
B．Trees can make the rain sink into the ground.
C．Trees can prevent drought and floods.
D．Tree roots can break up soil.

What do you do with your old clothes You might throw them away, sell them or give them to people in need. No matter which way you choose, it’s always you who have to decide what to do. However, California decided to push clothing companies to take care of the old clothes. As a result, the state passed the first US clothing recycling law (法律) on Sept 28, 2024.
This new law is expected to make less pollution. In 2021, about 1.2 million tons of old clothes were thrown away in California. While 95% are reusable or recyclable, only 15% are actually recycled.
The law said that companies making clothes have to set up a program to reuse, repair and recycle their goods. What’s more, they would have to pay for the costs of the whole program.
More than 150 groups, including environmental groups and some stores like Ikea, agree with the law. It would do good to the environment. It could also create over 1,000 new green jobs, reported The Guardian.
As a main polluter, the fashion industry (时尚产业) causes nearly 10% of the world’s carbon emissions (碳排放), according to the United Nations. Other countries like France and the Netherlands also have laws on clothing recycling programs. In France, for example, there are 47,000 recycling centers.
27．What does the numbers in Paragraph 2 show
A．The problem of clothes waste is serious. B．Companies are worried about the law.
C．The new law has had a great influence. D．Too many clothes are produced each year.
28．What do the companies have to do according to the law
A．Reduce the number of products. B．Sell their goods at a low price.
C．Set up a new environmental group. D．Pay for the clothing recycling program.
29．What’s the best title for the text
A．How to Reuse and Recycle Old Clothes at Home
B．The Rise of Green Jobs Because of the New Law

D．New Law Pushes Companies to Reduce Fashion Waste
If you put a recycling bin in your kitchen, good for you! You’ve made the first step to recycling, but here are other things that parents and kids can do to make recycling work better.
You’ve probably just got a rubbish bin where everything goes in your bedroom. But it’s a good idea to put a special bin for recycling paper. Then when it goes full, you can empty it into a larger recycling bin in the kitchen. You can also put a small recycling bin in the bathroom for any useless paper there.
Before you throw an item into the recycling bin, stop and think if you can use it again. Take plastic or glass items with yoghurt (酸奶), for example. After eating up the yoghurt, you can continue to use them for storing another food item.
If you decide to put an item in the recycling bin, it’s very important to follow this method. If it has food or drink in it, you must clean it before you put it in the recycling bin. It can’t be recycled with food still in it. You should put the item under the running water for a few seconds to clean it. This saves time for the workers in the recycling center to do more important work.
You mustn’t just do recycling for several months or even years and then return to your old habits. Recycling is a whole life task, so we’d better make recycling our new habit.

On November 13, 2023, people across Kenya (肯尼亚) took part in their first national tree-planting holiday. The holiday was created to encourage people to plant trees.
Kenya is famous for its beautiful forests and wildlife. But large areas of Kenya’s forests have been cut down, either for the wood or for farming.

Have you heard of microplastics (微塑料) Can we see them in our daily life Are they good or bad for human beings
Microplastics are very small. According to National Geographic, microplastics are usually less than five millimeters (毫米) in size. But they bring big problems. This small size lets them go everywhere, even in water and air. They don’t break down easily and can stay in the environment for hundreds of years. A new study said that by 2040, microplastic pollution could be twice as bad as it is now.
Microplastics are very small pieces of plastic. They come from many places. For example, about 60 percent of material made into clothes is plastic. Every time when the clothes are washed, they shed microplastics. When water bottles and other big plastic products are left outside, they break down slowly into microplastics. These microplastics can be bad for our health and even cause cancer. In August, the Conversation reported that scientists found microplastics in people’s brains for the first time. They may hurt brain cells (细胞) and change how the brain works.
Wild animals are also at risk from microplastic pollution. Each year, up to three million tons of microplastics end up in the ocean. Since they are too small to be seen, fish may eat them by mistake and become very sick.
To deal with the problem, scientists think the best way right now is to make and use less plastic. As students, we can reduce plastic things in our daily life, such as using glass or metal cups instead of plastic bottles and cups.

The Mayan king looked down at the city. There used to be some wonderful pyramids (金字塔), the fantastic gardens and the busy street markets. But now the city was silent and empty.
Many years before, the king found a big rainforest. “The trees are perfect to build my city.” said the king. Just then, an old man walked out behind a tree. “We have always looked after the rainforest and you must, too.” He said. “Don’t cut down the trees! Build your city somewhere else!” But the king neglected the old man’s advice and stuck to building his city near the rainforest. To build more houses, they cut down more trees from the rainforest. As the city grew, the king and his people became richer and richer. Everything seemed perfect, and the king was satisfied.
Until one day, things started to change. It didn’t rain and the rivers dried up. The rainforest finally turned into a desert. With little food and water, people started to leave the city. The king was very worried. Then he remembered the old man he once met. He went back and looked for him. Suddenly, the same old man appeared, standing alone in the desert.
“Look at what you’ve done!” complained the old man, full of disappointment.
The king fell to his knees and asked regretfully, “Please tell me what I should do.”
“Plant two trees for every tree you cut down and then everything may return.” The old man said.
Quickly, the king ordered his people to plant trees in the desert. After many years, the trees grew, the rain returned and the rainforest was filled with life again. First the animals and birds returned and then the people came back, too. The king was happy to see his city was coming back, slowly but surely.

Do you know about the red-crowned crane (丹顶鹤) It’s a really pretty bird with a bright red spot on its head. These birds like to live in wetlands (湿地), where they eat fish, insects, and plants. But the red-crowned crane is facing some serious problems now.
Their homes are being destroyed (破坏) because people want to build houses and farms there. This leaves the cranes without a safe place to live and find food. Some people even hunt them for their feathers (羽毛) or just for fun, which is really harmful to the cranes.
But there’s good news! Many kind people are trying to help the red-crowned crane. They’re creating special areas called “nature reserves” where the cranes can be safe. They’re also teaching others not to hunt or harm the cranes.
Saving the red-crowned crane is really important. You see, every animal has a special role in nature. If we lose the red-crowned crane, it could cause trouble for other animals and plants in the wetlands. And wetlands are super important for us humans, too. Because they help keep our water clean and our air fresh.
52．Where do red-crowned cranes like to live
A．In forests. B．In wetlands. C．In mountains. D．In cities.
53．What is one of the problems faced by the red-crowned crane
A．They have too much food. B．Their homes are being destroyed.
C．They are too shy to be seen. D．They can’t fly very high.
54．What are people doing to help the red-crowned crane
A．Building more houses in wetlands. B．Hunting them for their feathers.
C．Creating nature reserves for them. D．Teaching them to fly higher.
55．Why is saving the red-crowned crane important
A．Because they are very pretty.

In the 13th century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. 56 In western countries, people did not use paper money until the 15th century. However, people in China began to use paper money in the 7th century.
A Chinese man called Cai Lun invented paper almost 2,000 years ago. He made it from wood. 57 He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons (吨) of paper in our city. 58 This means that we are cutting nearly 48,000 trees every day.
Since it takes more than 10 years for a tree to grow, we must start using less paper now. If we don’t, we will not have enough time to grow more trees to take the place of those we use for paper.
59 We can use both sides of every piece of paper, especially when we are making notes. We can choose drinks in bottles. We can also use cotton handkerchiefs (手帕), but not paper ones. 60 If the shop assistant (店员) does give us a paper bag, we can save it and reuse it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使文章意思通顺、内容完整。
A．So how can we save paper
B．It takes 17 trees to make one ton of paper.
C．When we go shopping, we can use fewer paper bags.
D．He took the wood from the tree and made it into paper.
E．One of the things he discovered was that the Chinese used paper money.
Let’s say you are taking a walk along the road and you happen to see one or two waste bottles lying on the grass beside the road. What would you do
You may have different choices. Firstly, you can leave the bottles there as they are. It wasn’t you who threw them away. Why should you do something about it This is quite OK. Secondly, you can pick them up and throw them into a dustbin (垃圾箱). By doing this, you have walked a step further to help make our home clean. This action is a better choice. Thirdly, you might want to pick them up and give them to an old man or woman who collects waste for a living. If this is your choice, you have walked even further. You’re not only thinking about doing something for the environment, you’re also developing yourself to be a person who would think of others and help them.
As for young kids, they may always have such a question: “When do I grow up ” When does a child grow up And how can a kid know he or she has grown up These are interesting questions. As for us, 15-year-olds, who are finishing middle school, we’re no longer younger children. We should know whether or not we have grown up. When we start to have a sense of offering a helping hand for a cleaner and greener world, and when we have a loving heart to think more of others than of ourselves and are ready to help them, we can say that we have grown up.
Remember: If we help others, others will help us. If we do our best for nature, nature will offer its best to us in return!

At the age of 16, an American boy named Boyan Slat went on vacation in England. There, he saw more plastic bags than fish in the water. He almost couldn’t believe it. Three years later, Slat decided to set up the program The Ocean Cleanup in America to clean up ocean rubbish. Now the 25-year-old man is successful in setting up the world’s first ocean cleanup system with his team.
Every year, over 8 million tons of plastics end up in our oceans, and it can take up to 500 years to break down. Sea animals easily get stuck in plastic. They can even die if they eat it.
________ His plan was to make an environmentally-friendly large system to remove plastic rubbish from the ocean.

①For fans of sports, 2024 is an exciting year—the summer Olympics in France, the Winter Youth Olympic Games in South Korea and the UEFA European Championship. These events are fun but they bring environmental problems.
②Many players, coaching teams and fans fly in planes for the great sports events, which produces lots of carbon dioxide (CO2) —a greenhouse gas that leads to global (全球的) warming. One study has found that a person in a sports event can produce more CO2 than usual. Preparations for events can also influence people who live there, like the noise pollution, worse traffic and crowded restaurants.
③Although worldwide events can bring trouble to locals, it can actually be very helpful for businesses in the area. Restaurants, cafes and shops will have more customers. Also, sporting competitions has been shown to ▲ . A study of more than 7, 200 people found that watching live sport makes them feel much happier and less lonely.
④It’s not just the fans who benefit from that experience either. Having audience (观众) at a competition helps some players to perform better. For example, at the 2014 winter Olympics, a Russian player Yulia Lipnitskaya won a gold medal. She said this was because the crowd’s cheering gave her a sense of excitement, which helped her body respond (反应) more quickly.

It is important to learn how to protect our environment. Here is a 5R rule for us.
Reduce: If you want to reduce the waste, you should use things wisely. A large number of trees are cut down to make paper. If everyone uses paper wastefully, soon we would not have any trees left. So it is necessary to reduce the waste.
Reuse: You should always think of reusing the able things before throwing them away. For example, we should buy reusable forks and knives instead of ones we throw away. Bring cups to the coffee shop and cloth bags to the store. Give your clothes you do not use or the ones which are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters.
Recycle: Recycling uses less energy and fewer resources (资源 ). Bottles, cans (罐子) and paper cups can be easily recycled. They can be remade into the same thing or new things.
Recover: When you buy a box of apples, there may be a few rotten (腐烂的) ones, you have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
Repair: If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after repairing them.
Learn the rules to protect our environment. Let’s try our best to make the earth cleaner and more beautiful.
74．The writer explains the “Reduce” rule by ________.
A．telling a story B．asking a question
C．giving an example D．comparing things
75．The “Recover” rule advises us to ________.
A．use the old things again B．get back the useful parts

A．reduce them B．reuse them C．recycle them D．recover them
Trees naturally pull carbon dioxide (二氧化碳) out of the air. They store this carbon in their wood. This is one reason why people suggest planting trees as a way of fighting climate (气候) change. But when tees die, the wood rots (腐烂) and the stored carbon dioxide is released back into the air.
In 2013, a group of researchers wanted to see if they could keep wood from breaking down by burying (掩埋) it underground. They thought it might help keep carbon dioxide out of the air. Their plan was to bury a large amount of wood underground in Quebec, Canada. They planned to leave the wood there for 9 years, and then dig it up to see how much it had rotted. But as they were digging the hole to bury the wood, the scientists discovered a piece of old wood. It turned out to be an Eastemn red cedar tree that was 3, 775 years old. And it hadn’t rotted.
When the team tested the wood, they discovered that it had only lost about 5% of its carbon. It had held onto more than 95% of its carbon for almost 4, 000 years. The ancient wood was buried about 2 meters deep, and was covered with a layer of clay. The scientists think the clay protected the wood, keeping water and air from getting through. The clay also kept out insects and other creatures that might have helped break the wood down.
The discovery is important because it shows that wood vaulting (窖) can keep carbon out of the air for a long time. Wood vaulting is simple, and is a much cheaper way to store carbon than many other methods. The researchers believe that if it’s done in the right way, wood vaulting could keep as much as 10 billion tons of carbon out of the air every year. That’s about 20% of the greenhouse gases that are released into the air each year.
Clay soil is common around the world, but some scientists wonder if there might have been something special in the clay in Quebec. Experts say it’s important to discover exactly what conditions are required to make wood vaulting successful. The researchers say wood vaulting can’t solve climate change by itself. But it can be part of the solution.
77．What was the plan of the researchers in 2013
A．To keep wood to produce carbon dioxide. B．To use clay to prevent trees from rotting.
C．To dig up ancient wood to study its changes. D．To bury wood underground to test its rotting.
78．What does the underlined phrase “held onto” mean in paragraph 3
A．Lost. B．Kept. C．Shut. D．Cost.
79．What can we learn about wood vaulting in paragraph 4
A．It can work well if done correctly. B．It can keep carbon in the air for long.
C．It can prevent most greenhouse gases. D．It will cost more money to store carbon.
80．What does the success of wood vaulting depend on
A．The type of the wood. B．The insects around the wood.
C．The changes in climate. D．The conditions needed like clay.
81．What does the writer think of the influence of wood vaulting on climate change
A．Hopeful. B．Terrible. C．Accidental. D．Impossible.
A zero-waste life is a lifestyle that hardly creates any rubbish. So, a zero-waste store is about providing a kind of everyday and pleasant-looking zero-waste products to help people start on a zero-waste life journey.
“Zero waste” or “danshari” was first suggested by a French woman called Bea Johnson. Her idea is: live a life and try not to create any rubbish; use different kinds of ways to save the environment such as stopping the use of one-off objects; giving unwanted things to others or giving them away to organizations like the Red Cross.
Yu Yuan, 27, is deeply interested in this idea. She and her boyfriend have lived in Beijing for many years. And earlier she used to buy things without thinking about them carefully until she saw a video about “zero waste”, in which a family of four put the rubbish they produced every year in a jar (罐子). After watching the video, Yu wanted to experience this zero-waste lifestyle with her boyfriend.
A zero-waste life follows the 6R rule—Refuse, Reduce, Reuse, Repair, Recycle and Rot (腐烂). Over August—October when Yu followed the rule of zero waste 6R, she and her boyfriend Joe Harvey both produced only two cans of rubbish.
Now, the couple have opened a small shop in Beijing where they use wood products to take the place of plastic ones and cloth bags printed with environmentally friendly logos (环保标志). Most products sold in the store can be reused. The store also has second-hand books and CDs/DVDs with ideas to make the best of the used things.
“Those who once experienced the non-waste lifestyle have slowly changed their ideas.” says Yu, “The zero-waste lifestyle is not for ascetics (苦行僧). It is just around us at our finger-tips.” Yu expects some of her friends to join her on the road to zero waste.
82．Bea Johnson suggests that people should ________.
A．work hard for the Red Cross B．share objects with others
C．help their friends live comfortably D．try to produce no rubbish in life
83．We can see from the passage that Yu Yuan ________.
A．is influenced by the 6R rule B．often buys things she doesn’t need
C．offers plastic bags in her store D．likes listening to CDs very much
84．What Yu Yuan says in the last paragraph probably means that ________.
A．lots of people doubt the zero-waste lifestyle B．the zero-waste lifestyle is not difficult to live
C．her friends have followed her lifestyle D．she feels it hard to continue her lifestyle
