2025年中考英语一轮复习备考
①The world’s highest ski place, Chacaltaya, was closed after the 18,000-year-old glacier melted (冰川融化) in 2009. Many scientists agree that the glaciers around the world could disappear in this century, much faster than we thought.
②As we all know, the reason for this is global (全球的) warming. When certain gas such as carbon dioxide (CO ) is largely emitted (排放) into the atmosphere, it causes the greenhouse effect (效应) which makes Earth warmer.
③As Earth becomes warmer, glaciers melt quickly, and dark rocks are uncovered. Then these rocks take in more heat, causing the temperature to rise. As a result, the remaining snow on glaciers melts faster.
④The effects of global warming will be far-reaching and often devastating (毁灭性的). While the melting of glaciers may flood (淹没) some areas of Earth, in other places, it is making water disappear. An increasing number of heat waves and droughts (干旱) worldwide will also change the face of the world in the future.
⑤Global warming is a real problem, and one largely caused by human activity. Solving the problem is not easy, and there is no single magic way. However, we can begin it by lowering the amount of CO in our daily lives.
⑥Peter Miller, along with his wife, took part in a scientific test to see how much CO they could cut down in a month. The average (平均) U.S. household produces about 80 kilos of CO , which was more than twice the European average and almost five times the global average. Their final goal was to make less CO than most American families.
⑦First, they found out how much CO they were producing. Then they asked an expert for advice on how to reduce CO emissions. According to the expert’s advice, they made some changes to their house, replaced their lights, and changed some of their living habits. At the same time, they either biked, walked, or used public transportation. A month later, they saved 70% on electricity, 40% on gas, and drove half as much as others. Their daily CO emissions were less than the U.S. average, at 32 kilos.
⑧Protecting our planet starts small: change a light, open a window, walk or bike. With a little effort, and not much money, most of us can make a difference.

After 10 years of difficult talks, nearly 200 countries agreed to a new United Nations (UN) agreement to protect the world’s oceans. The agreement has been the first of its kind in 40 years. It plans to protect 30% of the open oceans by 2030.
Oceans cover about 71% of the Earth’s surface and are home to hundreds of thousands of different kinds of animals and plants. Healthy oceans are a very important part of a healthy planet. But the oceans are in trouble. Overfishing (捕捞过度) has had a terrible effect on many kinds of fish and other animals. Pollution from ships and other places has caused serious problems. In 1982, an agreement described the “ high seas (公海)”, but it did not protect them. In these areas, all countries have the right to fish, send ships, and do research. The high seas cover about two-thirds of the ocean. But now people only protect 1.2% of the areas.
Last December, over 110 countries agreed to protect 30% of their land and ocean areas by 2030. Without an international agreement, there was no way to make this goal meaningful for the whole ocean. The new agreement now makes this feasible.
The new agreement tries to turn 30% of the high seas into protected areas by 2030. It also says that activities planned for the high seas must first be examined to see what kind of influences they might have on the ocean environment. Businesses in some countries hope to make a lot of money by getting valuable things from the bottom of the sea. Other businesses hope to find plants or animals in the ocean that could lead to new discoveries and new medicines.
Many of the disagreements were about how valuable things would be shared between rich countries and poor ones. Poor countries wanted to make sure that the valuable things would help everyone, not just people in rich countries.
5．How many countries agreed to a new agreement to protect the world’s oceans
A．Nearly 20 countries. B．Very few countries.
C．Most countries in the world. D．Just a few countries.
6．What does Paragraph 2 mainly show us
A．The problems oceans face. B．Some ways to protect oceans.
C．Different kinds of ocean creatures. D．People’s different ideas about oceans.
7．What does the underlined word “feasible” in Paragraph 3 mean
A．Awful. B．Painful. C．Possible. D．Dangerous.
8．What’s the passage mainly about
A．The importance of healthy oceans. B．Overfishing and pollution in the oceans.
C．A new agreement to protect the open oceans. D．Disagreements between rich and poor countries.
①More researchers are turning to artificial intelligence (AI) to monitor the enivironment and support endangered creatures. Unlike traditional methods that can damage the environment or require considerable (相当多的) time and physical work, AI has the ability to quickly and effectively deal with large quantities of data (数据). Let’s learn more details together.
②Creatures are disappearing at a speed thousands of times faster than that millions of years ago, with one million creatures endangered. The United Nations set a goal in 2020 to safeguard at least 30% of Earth’s land and oceans by the end of 2030. “AI is imperfect but could make important discoveries faster and earlier.” says Nicolas Mialhe, founder of The Future Society, an organization that aims to better manage Al. “We need skilled humans to design AI models and check and collect data.”
③A type of AI model called a convolutional neural network (CNN) has been developed to recognize bird sounds. The CNN is able to pick out 75 kinds of the birds the researchers have. “Our results prove that AI is ready for recognizing creatures in the wild from sound.” says Maller, the team leader. “All that is needed now is more training data collected by humans.”
④Besides monitoring creatures in real time, AI can be used to model the impacts of human activities on the environment and rebuild historical changes. Researchers have used AI to discover how a century’s environmental damage in a river has led to creature loss.
⑤Although it is well-known that human activities have resulted in creature loss in rivers and lakes, little is known about which activities have the largest impact. “AI will do soon,” says Luisa Orsini, a researcher from the University of Birmingham.
9．What can we infer from the words Nicolas Miailhe’s and Maller’s said
A．AI models can be designed by everyone. B．AI models have alreadly developed perfectly.
C．AI’s ability needs CNN to discover and achieve. D．AI’s ability is much greater than what people imagine.
10．The meaning of the underlined word “impacts” in Paragraph 4 is the closest to ________.
A．effects B．chances C．secrets D．purposes
11．What is the structure of the article
A．①②③/④⑤ B．①②/③④⑤ C．①②/③④/⑤ D．①/②③④⑤
12．Which of the following is true according to the article
A．Al is only used in monitoring the environment and support endangered creatures.
B．Researchers have already prevented a century’s environmental damage in a river.
C．Creatures are disappearing faster than before with one million creatures endangered.
D．Al has spent more time dealing with large quantities of data than traditional methods.
Human activity is changing the surface and temperature of our planet. But new research shows it is also changing the sound of oceans and seas. Scientists say these changes may have an effect on many sea animals—from very small fish to huge whales.
Sound travels very far underwater. For fish, sound is a better way to sense their environment than light. They use sounds to communicate with each other. Sounds also help some ocean animals find food and avoid their hunters. Sounds help fish and other sea animals survive.
However, increased noise from humans is making it harder for these animals to hear each other. The noise comes from shipping traffic, underwater oil and gas exploration and other noisy human activities.
Experts say that effects of noise on sea animals are not well understood. However, some studies suggest that noise may cause hearing loss. The stress from human noise might also affect the immune (免疫) system. Many sea animals are showing higher levels of stress because of noise. Also, the number of sea animals has gone down by about half since 1970. In some parts of the ocean, scientists now record fewer animals singing and calling than in the past.
When people think of threats (威胁) facing the ocean, we often think of climate change, plastics and overfishing. But noise pollution is another necessary thing we need to consider. When it comes to something humans can do for the ocean, we need to think about how to make it quieter. Sound pollution may be easier to deal with than other ocean threats. You can reduce or turn off sound at once.
13．Sound is important for ocean animals for many reasons, except _________.
A．they use it to communicate
B．they use it to find food
C．they use it to see their environment
D．they use it to avoid hunters
14．What can we infer from the passage
A．Swimming in the sea will cause noise pollution.
B．Noise does more harm to sea animals than humans realize.
C．There is little that humans can do to reduce noise pollution.
D．Plastic pollution is the biggest threat facing oceans and seas.
15．Which of the following best shows the structure of the passage
A． B． C． D．
16．According to the article, which of the following statements is not true
A．Noise has an effect on huge whales as well as small fish.
B．Ocean animals might not hear each other because of increased noise from humans.
C．Many sea animals don’t have much pressure as humans.
D．Plastics or climate change are much harder to solve than noise pollution.
As we all know that recycling is a way to take rubbish and turn it into new products. It’s good for our environment.
There are a number of different recycling steps that allow materials to be used more than once. All kinds of materials can be recycled. Some of the most common things in use today include recycling plastic, glass, metals and paper. Things made of these materials include soda cans, plastic milk boxes, newspapers, computers and cardboard boxes.
Be sure to recycle everything you can in your house and school. There is almost a “recycle” rubbish can around. Be sure to drop your used aluminum (铝) cans and plastic bottles there. At home, be sure to put paper things like the newspapers, paper boxes and homework pages into the recycle box. Plastics are usually marked with an identification code (标识码) that shows a recycling symbol and a number from 1 to 7. This shows that the type of chemicals (化学品), or materials, is used in making the plastic. Used paper can be recycled around seven times.
Also we should set up a recycle station in every street, across the city and the country, so the cleaners can transport the rubbish conveniently. This is the only way out for handling rubbish without causing danger to the environment and our health.
Remember: There are a number of advantages for recycling. These include: Landfills——Recycling materials means less rubbish and saves space in landfills. Resources——When we use materials again, this means we can take fewer resources from the earth. Pollution——In general, recycling materials can produce less pollution. Helping to keep our environment clean. So, for ourselves, our children and our children’s children, let’s take action NOW!
17．What’s the key word in this passage
A．Reused. B．Recycling. C．Rubbish. D．Materials.
18．What are recycling’s advantages according to Paragraph 5
①using fewer resources ②saving more space ③saving more money ④producing less pollution
A．①②③ B．②③④ C．①③④ D．①②④
19．What does the underlined word “handling” in Paragraph 4 mean
A．Giving up. B．Dealing with. C．Taking out. D．Looking for.
20．The structure of this passage is ________. (①=paragraph)
A． B．
C． D．
Around the world, people are more and more worried about the environment. Many people now prefer products and companies (公司) that care about the earth and cause less pollution. This need for green products has led large companies to change their business.
Before, customers used cheap plastic (塑料) bags, and then threw them away. But now most supermarkets and stores usually provide reusable shopping bags for them. This causes less waste. They also offer more local products, because less energy is needed for carrying them from one place to another.
To help lower air pollution, big car factories are looking for other ways to control the amount of oil. Cars that use much less oil are very popular. Many companies are also developing fully electric cars. They produce no air pollution at all. Both kinds of cars have another advantage: They are cheaper to run and people don’t need to worry about oil prices.
The airline companies face an even greater green challenge. Airplanes use much more oil than cars. So many airlines are now developing planes that can run on some other kinds of oil. They create less pollution and cost less. The companies are also developing a new kind of planes, and some of them use only solar panels (太阳能板) to fly!
Green businesses used to be popular with only a small group of people. But now, more and more companies have to show they care about the environment. Many products are marked “green” in order to look nice. However, people still have to be careful when choosing green products. It’s important to make sure the products are as environmentally friendly as the businessmen say.
21．What are the advantages of electric cars according to the passage
a. Using cheap oil. b. Making little noise. c. Running at low costs. d. Producing no air pollution.
A．a and b B．c and d C．b and c D．a and d
22．The last sentence of the passage is written to ________.
A．show the green products are healthy
B．encourage people to buy green products
C．explain the importance of the environment
D．tell people to choose green products carefully
23．Which is the right structure of the passage
(①=Paragraph 1 ②=Paragraph 2, …)
A． B． C． D．
24．What’s the best title for the passage
A．Green Is Cheaper B．Green Saves the Earth
C．Green Is Good Business D．Green Makes Life Easier

As we all know that recycling is a way to take rubbish and turn it into new products. It’s good for our environment.
There are a number of different recycling steps that allow materials to be used more than once. All kinds of materials can be recycled. Some of the most common things in use today include recycling plastic, glass, metals and paper. Things made of these materials include soda cans, plastic milk boxes, newspapers, computers and cardboard boxes.
Be sure to recycle everything you can in your house and school. There is almost a “recycle” rubbish can around. Be sure to drop your used aluminum (铝) cans and plastic bottles there. At home, be sure to put paper things like the newspapers, paper boxes and homework pages into the recycle box. Plastics are usually marked with an identification code (标识码) that shows a recycling symbol and a number from 1 to 7. This shows that the type of chemicals (化学品), or materials, is used in making the plastic. Used paper can be recycled around seven times.
Also we should set up a recycle station in every street, across the city and the country, so the cleaners can transport the rubbish conveniently. This is the only way out for handling rubbish without causing danger to the environment and our health.
Remember: There are a number of advantages for recycling. These include: Landfills——Recycling materials means less rubbish and saves space in landfills. Resources——When we use materials again, this means we can take fewer resources from the earth. Pollution——In general, recycling materials can produce less pollution. Helping to keep our environment clean. So, for ourselves, our children and our children’s children, let’s take action NOW!

20．The structure of this passage is ________. (①=paragraph)
A． B．
C． D．
Around the world, people are more and more worried about the environment. Many people now prefer products and companies (公司) that care about the earth and cause less pollution. This need for green products has led large companies to change their business.
Before, customers used cheap plastic (塑料) bags, and then threw them away. But now most supermarkets and stores usually provide reusable shopping bags for them. This causes less waste. They also offer more local products, because less energy is needed for carrying them from one place to another.
To help lower air pollution, big car factories are looking for other ways to control the amount of oil. Cars that use much less oil are very popular. Many companies are also developing fully electric cars. They produce no air pollution at all. Both kinds of cars have another advantage: They are cheaper to run and people don’t need to worry about oil prices.
The airline companies face an even greater green challenge. Airplanes use much more oil than cars. So many airlines are now developing planes that can run on some other kinds of oil. They create less pollution and cost less. The companies are also developing a new kind of planes, and some of them use only solar panels (太阳能板) to fly!
Green businesses used to be popular with only a small group of people. But now, more and more companies have to show they care about the environment. Many products are marked “green” in order to look nice. However, people still have to be careful when choosing green products. It’s important to make sure the products are as environmentally friendly as the businessmen say.
