In our community, a new “Online Second-hand Exchange” activity started last month. It’s for teenagers to swap (交换) old but useful items, and it’s become very popular among us. 1 We just need to take photos of our old things, write short introductions and post them on the community’s WeChat group.
Before posting, we have to make sure the items are clean and in good condition—like storybooks with no missing pages or toys that still work. 2 For example, if you have a used basketball you don’t play with, you can swap it for a painting set or a pair of sports shoes.
3 When two people agree to swap, they can meet at the community center on weekends to hand over the items. Some volunteers also help check the items to make sure both sides are happy with the exchange.
This activity has many benefits. It helps us reuse old things instead of throwing them away, which is good for the environment. 4 We also make new friends while swapping, and it teaches us to communicate and negotiate (协商) politely.
A．It’s easy to join the activity.
B．Also, it saves us money because we don’t need to buy new items.
C． Everyone can swap items they don’t need for things they want.
D．We can even swap items with people from other communities.
E. The community center provides boxes for us to carry the swapped items.
5. Would you like to join such an online secondhand exchange activity Why or why not （请用英语回答，不超过20个词）

Social distancing during the outbreak of COVID-19 (新冠肺炎) helps save lives. It’s surprising to find that social distancing can also make the environment better.
Delhi, one of the most polluted cities in the world, went into a strict lockdown (居家隔离) on the 24th March, 2020. A study team looked at the PM2.5 particle concentration (浓度) in the air at the US embassy (大使馆) in Delhi before and after the lockdown. They found the PM 2.5 particle concentration dropped by 46%.
The new study also looked at solar power (太阳能) in Delhi. It has found that the reduction (减少) in air pollution has allowed a lot more sunlight to get through to solar panels in the city.
Overall, the amount of sunlight reaching solar panels in Delhi increased by around 8% in late March 2020, and 6% in April 2020 compared to similar dates in earlier years.
6．In the passage, which city has serious pollution problem
7．What helps bring more sunlight
8．When did the city go into a strict lockdown
9．What did the team also look at
10．How much sunlight reaching solar panels increased by in late March 2020
根据短文内容回答下列问题。
Water is an essential element for all forms of life on Earth. It covers about 71% of the Earth’s surface, but the amount of fresh water available for human use is relatively limited. In nature, water is constantly in a cycle. It evaporates from the surface of oceans, lakes, and rivers, turns into clouds, and then falls back to the ground as precipitation, such as rain, snow, sleet, or hail. This water cycle is crucial for maintaining the balance of the ecosystem.
However, water pollution has become a serious problem nowadays. Industrial waste, sewage from cities, and agricultural chemicals like pesticides and fertilizers are being discharged into water bodies. This not only harms aquatic plants and animals but also poses a great threat to human health when we use or drink the polluted water.
To make matters worse, water scarcity is another challenge. In some arid regions, there is simply not enough water to meet the daily needs of people and industries. Even in areas where water seems abundant, improper use and waste can lead to shortages in the long run.
Thankfully, there are many ways we can take to protect water resources. For example, we can save water in our daily lives by turning off the tap when not in use, fixing leaky faucets promptly, and using water-saving appliances. On a larger scale, governments and organizations should enforce strict laws and regulations to control water pollution, and promote water-recycling and desalination technologies.
11．What percentage of the Earth’s surface is covered by water
12．What forms can precipitation take
13．What are the main causes of water pollution mentioned in the passage
14．Why is water scarcity a problem even in areas where water seems abundant
15．What are some ways individuals can save water in daily lives according to the passage
16．If you were a government official, what other measures would you take to protect water resources Explain why.
Answer the questions（根据短文内容回答下列问题）
Different from Earth Day which falls on April 22 every year, Earth Hour has been known for its “lights off” moment. On March 22, 2025, from 8:30 PM to 9:30 PM, millions turned off their lights to show they cared about the Earth. This year’s Earth Hour, with the theme (主题) “Create the Biggest Hour for Earth”, was even more important because it shared the same day as World Water Day. However, it’s not enough to have such an hour every year. What matters is how we can be kinder to the earth every day.
Planet-friendly food
You might not realize it, but the meat industry has a huge influence on forests around the world. Large numbers of trees are cut down to make space for soy (大豆) and other plants that are used to feed animals. Have a chat with your parents about going meat-free, even for a few days every week. Also, foods like vegetables, fruit and nuts are helping the planet.
Go green and save money, too
Electricity (电) produced by burning fuels like oil, coal and gas causes global warming and pollution. Ask your parents how they heat your home and suggest using green energy like wind or solar power (太阳能). Another tip is to remember to turn off the electricity whenever you leave a room. Cutting down on screen time is actually good for both your health and the earth.
Waste Less, Help more
Waste is a big problem! We’ve talked about saving electricity. What about food waste Every year, 1.3 billion tonnes of food is wasted around the world. That’s one-third of the total amount, which can feed up to 1.26 billion people. Try to talk to your parents about buying a proper amount of food. More importantly, find some ways online for leftover food at home.
17．When did Earth Hour take place in 2025
18．Why was Earth Hour 2025 especially important
19．How does the meat industry negatively affect forests
20．Why is electricity produced by burning fuels harmful to the environment
21．One-third of the world’s food is wasted, isn’t it
22．As teenagers, what can we do to contribute to Earth Hour and environmental protection beyond just turning off lights for one hour
The Iceberg Project: A Bold Solution
In 2017, an Emirati company proposed towing icebergs from Antarctica to the UAE. Each iceberg holds 20 billion gallons of fresh water—enough for 1 million people for 5 years. Special nets would prevent melting during the 10-month journey. If successful, it could supply drought-hit areas globally.
However, critics highlight risks. Melting icebergs might disrupt ocean currents. The $60 million cost per iceberg is high, and storms could sink them. Dr. Jones from MIT suggests focusing on cheaper methods like desalination. “While innovative,” he says, “it’s like using a helicopter to deliver pizza.”
Despite doubts, the project continues research. Engineers test coating icebergs with insulation foam. If costs drop, the first iceberg might arrive by 2030.
23．How much water can one iceberg provide
24．What is the main purpose of special nets
25．Why does Dr. Jones compare the project to “a helicopter delivering pizza”
26．List two risks mentioned about the project.
27．What solution are engineers testing to improve the project

Water is not only important for our life but also plays a significant role in nature. The water cycle is a continuous process that includes evaporation, condensation, and precipitation. When the sun heats the water in oceans, lakes, and rivers, it turns into water vapour and goes up into the air. As the water vapour cools down, it turns into tiny water droplets, forming clouds. Then, the water droplets fall back to the Earth as rain, snow, or hail.
The water cycle is very important for our environment. It helps to regulate the Earth’s temperature and provides fresh water for plants, animals, and humans. However, human activities can have an impact on the water cycle. For example, deforestation can reduce the amount of water that is absorbed by the soil and evaporated into the air. Climate change can also cause changes in precipitation patterns, leading to more floods or droughts in some areas.
28．Please give a brief summary of the water cycle process. (No less than 40 words)
29．According to the passage, analyze the impact of human activities on the water cycle. (No less than 40 words)
30．As a middle school student, what can you do to protect the water cycle Please put forward two suggestions. (No less than 40 words)

Xiaoya joins in an activity and learns how to save water.
One day, she goes to visit her friend, Zhouzhou. Zhouzhou is excited to see her. She talks with Xiaoya and washes some fruit for her. But when she is washing apples, she doesn’t use a basin (盆子) to collect water but wash them with running water. Xiaoya says, “I think you’d better wash the fruit in a basin. It helps save water.” But Zhouzhou doesn’t think it matters a lot. So she still keeps the water running and washes apples. Then Xiaoya comes to her and tells her a story she knows from an activity. There is a small village in Africa. People there can only take showers once a week. And they even don’t have enough clean water to drink. After hearing the story, Zhouzhou feels sad for the African people. She thinks she should learn to save water from now on.

Water shortage is a big problem in many parts of the world. In some dry places, not having enough water makes daily life very hard. People there have trouble finding enough water and getting clean water to drink.
One good way to solve this problem is to dig wells (井) . With the help of modern technology, wells can now be dug near people’s homes. Special machines dig deep into the ground to find fresh water. After finding the water, a pump is put in. Then people can easily get water from the well. Having wells nearby is great because people don’t need to walk far to get water, and the water they get is clean and safe to drink.
Collecting rainwater is another useful way. It usually needs many people to work together to build water tanks. Some tanks are built on rooftops, and some are built at schools. These tanks collect and store rainwater. The stored rainwater can be used when there is no rain. At school, these rainwater collection systems are like good teaching tools. Students can learn how to save water and protect the environment by using them.
Reusing water also helps a lot when there is not enough water. Water used for washing clothes or taking showers doesn’t have to be thrown away. Even the water used for washing dishes, which can’t be used for drinking or cooking, can be used again. It can be used to water plants and fruit trees. This helps keep the plants alive and saves water at the same time.

March 22 is World Water Day. It reminds us to save water, because water is the most important natural resource on the Earth.
Water covers more than 70% of the Earth’s surface, but most of that is sea water. People can’t use it directly in daily life. Fresh water takes up only 2.5% of the total water.
People in many places are facing serious water problems. One of them is water pollution. Many kinds of waste from cars, factories, farms and homes make rivers, lakes, and oceans dirty. Polluted water is very bad for people’s health. And dirty water is also bad for sea life. Now, 34% of fishes are dying out.
The biggest source (来源) of pollution comes from cars and factories. In the beginning, waste from cars and factories pollutes the air. Then, when it rains, the rainwater comes down and makes our drinking water dirty.
Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save water. Here is some advice.
●Turn off the tap while you are brushing your teeth. You can save as much as 450 litres (升) of water each month.
●Leaky (漏水的) taps waste a lot of water. Fix them right away!
●You can easily cut your shower time short, and you’ll be still clean.
●When you wash the dishes, don’t let the water run.
●Only wash clothes when you have a lot to wash. If your washing machine isn’t full, you’re wasting water.
40．What does “it” refer to in Paragraph Two
41．Which sentence in the passage has the similar meaning to the following one
Water which is polluted can make people unhealthy.
42．Ask ONE question about Paragraph Four with Where, How…
43．According to the advice mentioned in the passage, how can you save water when you take a shower
44．What other ideas do you have to save water Please give two ideas.
There are some easy things you can do to protect the earth:
Plant flowers, grass or trees.
Whenever you visit a park or beach, take away what you take there. Keep rubbish in a bag until you can put it in a dustbin (垃圾桶).
Turn off the lights and TV set when you leave the room. This can save a lot of electricity.
Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.
Give your old books and magazines to a library instead of throwing them away.
Give your old clothes to poor children you know instead of throwing them away.
Use both sides of paper.
Stop pouring dirty water into the rivers or lakes nearby.
Encourage all your friends to do the same things as you do to help protect the earth.
You don’t have to wait until Earth Day to do these things. Make every day Earth Day. If everyone makes a contribution (奉献) to protecting the environment, the earth will become much more beautiful.

The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only use the 3 % of the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.
Now more water is needed. The problem is: Can we avoid a serious water shortage (短缺) later on Firstly, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities, water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it’s already in use in many parts of the world. Scientists are trying to find a cheaper way to do it. So you see, if we can find a way out, we won’t be in danger of drying up.

Nowadays water pollution is becoming an important problem. We can hear about water pollution from TV sometimes. A report shows that more than one third of the country’s industrial waste water flows directly into rivers and lakes.
The water environment in most cities around the country is declining(下降). An official report from the Ministry of Environment Protection(环保总局 ) shows that among the investigated 131 rivers that flow through cities, 36 are severely(严重) polluted, and nearly 60 others polluted.
Since the Songhua River benzene(苯) pollution incident in 2005, over 140 pollution cases have been reported.
The Yellow River, an important water resource for North China, is suffering from serious pollution. Nearly 40 percent of its mainstream has been severely polluted.
And situation is no better for the Huai River, in which the country has invested(投入) most. It is also a severely polluted river.
Water, like the air, is another basic substance(物质) of human life. But the fact is that more and more water is being polluted. The available drinking water is declining. Some factories are only busy developing their factories, without any thought of protecting the environment. They pour the waste water into rivers and oceans as they like. Although sometimes they are forbidden and punished, after that they will continue to do as usual because of money.
In brief, it’s time for us to take steps to improve our living environment before it is too late.

There is no doubt that water is one of the most important resources for man. It is the source of all life.
But in fact we’re facing serious water problem.
Problems
Although water covers 71 percent of earth’s surface, we can only use a very small part of it. It’s about 3 percent and it’s in lakes, rivers and underground. Today, there are over 663 million people living without a safe water supply（供应） close to home, according to the United Nations.
Themes（主题）
To remind people of the importance of water, the UN first set WORLD WATER DAY in 1993. It is celebrated on March 22 each year. Every year has a theme.
Year Theme Year Theme
2020 Water and climate change 2021 Valuing water
2022 Groundwater-Making the Invisible Visible 2023 Accelerating Change
Solutions
In fact, many governments and organizations have already taken actions to offer good solutions. In some countries, people have their own solutions for saving water and reusing waste-water.
●Turn off the water South Africa is one of the world’s driest countries. The Be the Hero website gives some advice on how to save water in the bathroom. Turn off the water while brushing your teeth. It can save 600 liters a month.
● ________ Collecting rainwater is an important way to save water in Germany. Most houses built in the last few years have rainwater collection systems. If you don’t have the system, just put a bucket（桶） under your roof when it rains.
●Keep the grass longer Most Australians have a grass lawn around their home. It is best to keep the grass longer. That way the grass covers the ground, it helps reduce evaporation（蒸发）.
Actions
As students, we should try our best to fight against the problem of water waste. What we can do is to support charities, take part in the World Water Day activities, be careful with how we use water in our own lives. We can also visit the UN World Water Day website to find out about an event near us and help spread around the world about the importance of saving water.

Why Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only use the 3 % of the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.
Now more water is needed. The problem is: Can we avoid a serious water shortage later on Firstly, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities, water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt (盐) out of the sea water. This is expensive, but it’s already in use in many parts of the world. Scientists are trying to find a cheaper way to do it. So you see, if we can find a way out, we won’t be in danger of drying up.
