阅读下面短文，掌握其大意，然后从各题所给的 A、B、C、D 四个选项中，选出最佳选项。
Our school recently started a “Green Campus” project, and it has changed our daily life in many ways. Before the project began, we didn’t pay much attention to environmental protection. We often used disposable lunch boxes and plastic bottles, and litter 1______ everywhere in the playground.
When the project was announced, our teacher asked us to discuss how we could help 2______ the earth. We came up with many good ideas: setting up recycling bins in classrooms, planting more trees in the school yard, and stopping using single-use plastics. Everyone 3______ excited to take part in the activities.
The first thing we did was to put recycling bins for paper, plastic and glass in each classroom. At first, some students forgot to sort their waste, but with the help of our monitor, we 4______ used to doing it soon. By last week, we 5______ more than 50 kilograms of paper and 300 plastic bottles. These materials will be sent to factories and 6______ into new products.
Then we planted 20 young trees near the school gate. We took turns to water them every day. Now the trees 7______ green and lively, and they make our school much more beautiful. Our teacher told us that trees 8______ a lot of carbon dioxide and produce oxygen, which is good for our health.
Another activity was a “No Plastic Day” last Friday. On that day, no one brought plastic bags or disposable tableware to school. We brought our own cloth bags and metal lunch boxes. Many students said they 9______ the experience and would continue to use reusable items at home.
During the project, we also invited an environmental expert to give a talk. He told us about the serious problems caused by pollution and how small actions 10______ a big difference to the earth. We learned that even simple things like turning off the tap when brushing teeth or walking to school instead of taking a car can help save the environment.
Now, our school 11______ a better place. The playground is clean and tidy, and we can breathe fresh air every day. More importantly, all of us 12______ a strong sense of environmental protection. We know that protecting the earth is not just a slogan, but something we need to do every day.
By the time we graduate, we 13______ many more activities to make our school greener. We also hope that our families and communities will join us. After all, the earth is our common home, and it’s our duty 14______ it. We believe that if everyone plays a part, the world 15______ a more beautiful place for us to live in.

A Community’s Fight Against Plastic Pollution
Last year, the people of Green Town noticed a serious problem: their local river was filled with plastic bags, bottles and other waste. The river, which used to be clean and clear, had become dirty and smelly. Fish and birds were dying, and children could no longer play near the water.
To solve the problem, a group of volunteers started a “Clean River” campaign. They first organized a big clean-up day. Over 200 people joined in, including students, teachers, and local business owners. They spent the whole day picking up litter from the riverbank and the water. By the end of the day, they had collected more than 3 tons of waste, most of which was plastic.
After the clean-up, the volunteers didn’t stop. They visited local schools to give talks about plastic pollution. They taught students how plastic harms the environment and how to reduce plastic use. They also asked local shops to stop giving out free plastic bags and offer cloth bags instead. Many shops agreed to the request.
Another thing the volunteers did was to set up recycling stations along the river. People could bring their plastic waste there to be recycled. The volunteers also started a “Plastic-Free Weekend” activity. Every Saturday and Sunday, people were encouraged to use no plastic products. Those who followed the rule could get a small prize, like a reusable cup or a plant.
After six months of hard work, the river in Green Town has changed a lot. It’s clean again, and fish have returned. More people have realized the importance of environmental protection. The “Clean River” campaign has not only saved the local river but also brought the community closer together.

A. The local river was polluted by plastic waste.
B. There were not enough shops in the town.
C. Students didn’t have enough environmental classes.
D. The community was not united.
( )2. What did the volunteers do to solve the problem
① Organized a clean-up day. ② Gave talks in schools. ③ Stopped all shops from selling plastic products. ④ Set up recycling stations.

( )3. What can we learn from the passage
A. Plastic pollution is easy to solve in a short time.
B. Only volunteers can protect the environment.
C. Small actions can make a big difference to the environment.
D. The river in Green Town is still dirty now.

The Story of a “Green” School
Sunshine Middle School is not like other schools. It’s known as a “green school” because of its efforts to protect the environment. Let’s take a look at how the school does it.
First, the school uses clean energy. It has solar panels on the roof of the classroom buildings. These panels collect energy from the sun and use it to power the lights and computers in the school. By using solar energy, the school saves a lot of electricity every year and reduces air pollution.
Second, the school has a “waste sorting” system. Each classroom has three recycling bins: one for paper, one for plastic, and one for glass. Students learn how to sort waste in class, and they take turns to check the bins to make sure everyone follows the rules. The school also has a compost bin for food waste. The compost is used to fertilize the plants in the school garden.
Third, the school encourages students to go green in their daily life. Students are asked to bring reusable water bottles and lunch boxes. The school cafeteria doesn’t provide disposable tableware. Every month, the school holds an “Environmental Activity Day”. Students take part in activities like planting trees, cleaning up the park near the school, and making crafts from waste materials.
The “green” practices have brought many benefits. The school’s electricity bill has gone down by 30% since using solar panels. The school garden is full of flowers and vegetables, which students can pick and eat. Most importantly, students have developed good environmental habits. Many of them now use reusable products at home and tell their families to save energy.
Sunshine Middle School proves that schools can be both educational and environmentally friendly. It sets a good example for other schools to follow.
( )1. Why is Sunshine Middle School called a “green school”
A. Because it has a lot of green plants.
B. Because it uses clean energy and protects the environment.
C. Because all students wear green uniforms.
D. Because it’s located in a green area.
( )2. What do students do on the “Environmental Activity Day”
A. They have classes about the environment.
B. They check the recycling bins in classrooms.
C. They plant trees and clean up the park.
D. They make compost from food waste.
( )3. What benefit has the school got from the “green” practices
A. The school has more students.
B. The school’s electricity bill has decreased.
C. The school garden has more flowers than vegetables.
D. Students no longer use disposable products at home.
C
How to Live a Low-Carbon Life
Living a low-carbon life means reducing the amount of carbon dioxide we produce. It’s good for the environment and can also save money. Here are some simple ways to live a low-carbon life.
First, save energy at home. Turn off the lights when you leave a room, and don’t leave the TV or computer on standby. Use energy-saving light bulbs, which use less electricity and last longer. When washing clothes, wash them in cold water instead of hot water. This can save a lot of energy.
Second, reduce transportation pollution. Try to walk or ride a bike for short trips. If you need to go further, take public transport like buses or subways instead of driving a car. Carpooling with friends or family is also a good idea. It reduces the number of cars on the road and saves fuel.
Third, cut down on plastic use. Use reusable bags when shopping, and avoid buying products with too much packaging. Bring your own water bottle instead of buying bottled water. Use cloth napkins instead of paper napkins. All these small changes can reduce plastic waste.
Fourth, eat locally and seasonally. Food that is transported from far away uses a lot of fuel. Eating local food not only reduces carbon emissions but also supports local farmers. Seasonal food is usually cheaper and fresher, and it doesn’t need to be stored in cold rooms for a long time.
Finally, reuse and recycle. Reuse items as much as possible. For example, you can use glass jars to store food, or use old clothes as cleaning rags. Recycle paper, plastic, glass and metal. Many communities have recycling programs, so make sure to sort your waste correctly.
Living a low-carbon life is not difficult. It’s all about making small changes to our daily habits. If everyone lives a low-carbon life, we can make the earth a better place.
( )1. What does living a low-carbon life mean
A. Producing more carbon dioxide.
B. Reducing the amount of carbon dioxide.
C. Saving more money by using less energy.
D. Only eating local and seasonal food.
( )2. Which of the following is a way to save energy at home
A. Using hot water to wash clothes.
B. Leaving the TV on standby.
C. Using energy-saving light bulbs.
D. Turning on lights in all rooms.
( )3. What can we infer from the passage
A. Living a low-carbon life is expensive.
B. Only big changes can help protect the environment.
C. Carpooling is not a good way to reduce pollution.
D. Small habits can contribute to environmental protection.

阅读下面短文，根据短文内容回答问题。
A Student’s Environmental Project
Li Ming, a 九年级 student from Beijing, started an environmental project last term. His goal was to encourage his classmates and family to reduce plastic use.
At school, Li Ming first did a survey. He found that each student used about 5 plastic straws and 3 plastic bags every week. That added up to a lot of plastic waste. So he talked to his teacher and suggested setting up a “No Plastic Straws” campaign in the school cafeteria. The teacher agreed, and the cafeteria stopped providing plastic straws. Instead, it offered paper straws and metal straws that students could reuse.
Li Ming also made posters about plastic pollution and put them up in classrooms and hallways. He explained to his classmates how plastic harms the environment. Many students supported him and started bringing their own reusable straws and bags to school.
At home, Li Ming encouraged his family to change their habits. He asked his parents to use cloth bags when shopping and to avoid buying bottled water. He also helped his mom set up a recycling corner at home for paper, plastic and glass. His little sister even started to make crafts from old plastic bottles.
After three months, Li Ming saw great changes. The number of plastic straws used in the school cafeteria dropped by 90%. His family now produces much less plastic waste. More importantly, many of his classmates and neighbors have joined in reducing plastic use.
Li Ming said he was happy with the results of his project. He realized that everyone can do something to protect the environment, and small actions can make a big difference.
1.What was Li Ming’s goal of starting the environmental project
2.What did Li Ming do first at school for his project
3.How did Li Ming encourage his family to reduce plastic use

An Environmental Activity I Joined
Last Sunday morning, I joined a “Clean Park” activity organized by our community. It was held because the park had become dirty with litter like plastic bottles and paper bags.
When I arrived, many volunteers were already working. We divided into groups: some picked up litter, some sorted the waste into recycling bins, and others told visitors not to throw rubbish. I helped pick up litter near the lake. It was tiring but satisfying to see the park become clean.
This experience made me realize that protecting the environment is everyone’s duty. Small actions like picking up litter can make our surroundings better. I’ll keep taking part in such activities and encourage my friends to join me.
