二、完形填空(共15小题，每小题1分, 计15分)

Our planet is facing many environmental problems. Air pollution, water pollution, and waste are becoming more and more serious. But the good news is — every one of us can    11    a part in making the world greener.

We can start with small things. For example, we should turn off lights when we leave a room. This helps us    12    electricity. We can also reuse plastic bags or use cloth bags when shopping. This reduces the number of plastic bags that    13    each day.

Many schools are now teaching students to    14    waste into different groups — paper, plastic, glass,

and metal. Then, these materials can be    15    and turned into new products. Recycling is very important, because if we don’t do it, more rubbish    16    in landfills.

Trees are also very important. They give us oxygen and help clean the air. But many people still    17   trees to build houses or make paper. This is very    18    to the environment. We must stop this and plant more trees every year.

In the future, more   19    will be used in cities. For example, buses and cars may run on solar or electric power. This means less pollution and cleaner air. Also, new laws    20    soon to help protect the environment.

Students can also help by joining school clubs. Many schools have “Green Teams” that organize clean-up days or planting activities. If you join one, you’ll find that caring for the Earth is not only useful — it’s also    21   !

Some people say, “One person can’t change the world.” But that’s not true. If every student in our school starts recycling, and every family turns off unused lights, big changes    22   .

Remember: every small action matters. You can    23    your friends and family to join you. Don’t wait — start today!

We only have one Earth. If we all    24    about it and act now, we can make sure it stays beautiful and healthy for the next generation. The future    25    us — and it starts with you.

The Green Club at Sunshine Middle School has been making waves recently. Every Wednesday afternoon, instead of going straight home, members of the club stay behind to patrol the campus. Armed with gloves and trash bags, they carefully pick up used batteries, empty plastic bottles, and piles of waste paper scattered around the playground and corridors. After sorting these wastes into different categories, they send them to the local recycling center every Friday morning.

Last month, the club launched a creative campaign called "No Car Day". They designed posters and gave speeches during the morning assembly, persuading parents and teachers to leave their cars at home. The response was amazing. On that day, the streets around the school were filled with students riding bikes or walking to school. The club even measured the air quality and found that the PM2.5 level dropped significantly. The air felt fresher, and the streets were much quieter. Now, the club plans to make this activity a monthly tradition.

26. What do members of the Green Club do every Wednesday afternoon?

A. They play sports on the playground.         B. They collect and sort waste on campus.

C. They attend extra classes for science.        D. They deliver speeches in the hall.

27. How often do they send the sorted waste to the recycling center?

A. Once a week.                          B. Twice a week.

C. Once a month.                         D. Every other day.

28. Which of the following is NOT a result of "No Car Day"?

A. The air quality improved.                B. The streets became quieter.

C. More parents drove their cars.            D. Students rode bikes to school.

B

Imagine waking up in the year 2050. Thanks to breakthroughs in green technology, our cities have transformed dramatically. First, the roads are no longer dominated by noisy, gasoline-powered cars. Instead, most vehicles run on electricity or solar power, gliding silently through the streets. This shift has not only reduced air pollution but also lowered the noise levels, making the city a more peaceful place to live.

Second, the gray concrete buildings we see today are covered with lush rooftop gardens. These vertical gardens act as the "lungs" of the city, absorbing carbon dioxide and releasing fresh oxygen. Moreover, smart robots will handle waste management. Equipped with sensors, these robots can automatically identify and separate recyclable materials from household waste with high accuracy. However, scientists warn that technology alone isn't a silver bullet. If we continue to waste resources without thinking, even the smartest
