Call for Low-Carbon Living—Join Our"Green Earth"Campaign
Dear citizens,
Climate change has become an urgent global issue,with extreme weather events like typhoons and droughts occurring frequently.Rising sea levels threaten coastal areas,and declining biodiversity breaks ecological balance.To respond to the national carbon neutrality goal and protect our common home,our community launches the"Green Earth"campaign this year.We invite all residents to adopt eco-friendly lifestyles.
During the campaign,we will organize monthly themed activities.We’ll hold garbage classification lectures with environmental experts,set up second-hand exchange markets for resource reuse,and arrange quarterly tree planting events.All participants are encouraged to reduce energy consumption,use public transport or bicycles,and avoid single-use plastics.
To support your low-carbon journey,we will provide free reusable water bottles and garbage sorting kits for each participating family.The kit includes a classification guide,labeled bins and biodegradable bags.We also have a"Green Star"reward system—outstanding families will get eco-friendly gifts monthly.
You can sign up online via our official WeChat account or offline at the community service center before December 15.Let’s take action hand in hand to build a greener community for future generations!

Last summer,I joined a volunteer team for a wetland protection project in my hometown.The wetland on the city’s outskirts used to be a bird paradise,but in recent years,nearby factories discharged untreated wastewater and tourism was overdeveloped.The water turned turbid,reeds withered,and many bird species disappeared.
We met our team leader Dr.Li,an environmentalist with 20 years of wetland protection experience.He shared shocking data:the wetland’s pollution index rose by 60%in five years,and migratory birds decreased by 70%.He told us wetlands are natural"water purifiers"that purify water,regulate climate and prevent floods.
Our first task was garbage cleaning.Plastic bags,beverage bottles and abandoned fishing nets were everywhere.We put on gloves and picked up wastes carefully.It was tiring,but when I saw a heron flying over the cleaned area,I felt a strong sense of achievement.
During the one-week project,we planted native plants along the wetland banks to prevent soil erosion.Dr.Li taught us to identify bird species and monitor their activities.One evening,we saw a group of wild ducks resting by the water—a scene I hadn’t seen in years.
This experience taught me environmental protection is not a slogan but daily action.Every small effort,like picking up garbage or planting a tree,can restore nature.Protecting wetlands is protecting our own home.
24. Why did the writer join the wetland protection project
A. To take photos of rare birds
B. To learn about tourism development
C. To participate in ecological protection and realize its importance

Plastic pollution has become a severe environmental problem worldwide.Every year,millions of tons of plastic waste enter oceans and landfills.Marine animals often mistake plastic bags for jellyfish and die,and microplastics enter the food chain,threatening human health.Fortunately,new solutions have emerged in 2025.
Biodegradable plastic is one promising technology.Unlike traditional plastic that takes hundreds of years to decompose,it is made from corn starch and sugarcane.It breaks down into harmless substances like water and carbon dioxide in months.Many food companies now use it for packaging and tableware,and supermarkets offer biodegradable shopping bags.
Plastic recycling robots are another innovative solution.Equipped with advanced sensors and AI,these robots can quickly identify and sort different types of plastic waste.They work 24 hours a day in landfills and recycling centers,greatly improving efficiency.In cities like Hangzhou and Shenzhen,the plastic recycling rate has increased by 30%since their use.
Scientists are also developing technology to convert plastic waste into energy.Through thermal decomposition,plastic is heated to high temperatures in a sealed environment,turning into gas and oil that can be used as electricity or fuel.This not only reduces pollution but also provides a new energy source.
However,technology alone is not enough.Everyone must reduce plastic use in daily life—bring reusable water bottles and shopping bags,avoid over-packaged products,and join community cleaning activities.Only by combining technology and public participation can we completely solve plastic pollution.
28. What is biodegradable plastic made from
A. Traditional plastic materials B. Corn starch and sugarcane
C. Recycled plastic waste D. Artificial chemicals
29. How do plastic recycling robots improve efficiency
A. Produce new plastic products
B. Convert plastic to energy directly
C. Identify and sort plastic quickly with sensors and AI
D. Decompose plastic into harmless substances
30. What is the advantage of converting plastic waste into energy
A. Reduces pollution and provides new energy B. Speeds up plastic decomposition
C. Increases biodegradable plastic production D. Reduces recycling costs
31. What can we infer from the passage
A. Biodegradable plastic will replace traditional plastic soon
B. Recycling robots are used in all Chinese cities
C. Public participation is necessary for solving plastic pollution
D. Thermal decomposition technology is widely used
D
The conflict between economic development and environmental protection is a hot global topic.With population growth and improving living standards,resource demand is rising.Some people believe economic development should be prioritized,even at the cost of environmental damage.But I firmly hold that environmental protection and economic development can coexist harmoniously,and only balance can achieve sustainable development.
History proves ignoring environmental protection for economic growth backfires.In the past,some industrial regions pursued rapid development without considering environmental costs.Factories discharged untreated wastewater into rivers,and large-scale deforestation destroyed ecosystems.These regions suffered severe pollution,harming people’s health and hindering long-term economic development.Restoring the environment took decades and huge funds.
On the contrary,regions adhering to green development have achieved both environmental improvement and economic growth.A small city in Zhejiang Province abandoned traditional industrial development and focused on eco-tourism and green agriculture.It invested in protecting forests and wetlands,building ecological parks.It also promoted organic farming,producing pollution-free products.These efforts attracted numerous tourists and boosted organic product sales,significantly increasing residents’ income.The city has become a national green development model.
With green technology development,more enterprises realize environmental protection is an innovation opportunity.Investing in renewable energy like solar and wind power,developing eco-friendly products,and improving energy efficiency not only reduces pollution but also saves costs and enhances competitiveness.International companies like Tesla and IKEA have succeeded with green strategies,winning environmentally conscious consumers.
In conclusion,environmental protection and economic development are not opposing forces.We should abandon the outdated idea that development requires sacrificing the environment.Governments should formulate strict environmental policies and support green industries.Enterprises should take social responsibility and invest in environmental protection.As individuals,we should also contribute.Only in this way can we achieve both economic prosperity and environmental beauty.
32. What is the author’s main opinion
A. Economic development should be prioritized
B. Environmental protection and economic development can coexist harmoniously
C. Environmental protection hinders economic development
D. They are completely opposing forces
33. What happened to regions that ignored environmental protection
A. Achieved sustainable economic development
B. Suffered pollution and long-term economic setbacks
C. Attracted more tourists and promoted industries
D. Saved money on environmental restoration
34. Why does the author mention the Zhejiang city
A. To show eco-tourism’s profitability
B. To exemplify balanced development
C. To explain organic agriculture development
D. To prove environmental protection’s importance
35. What is the best title for this passage
A. The Dangers of Ignoring Environmental Protection
B. Green Technology for Economic Growth
C. Balancing Environmental Protection and Economic Development
D. The Importance of Eco-Tourism

Last weekend,I participated in a"Clean Beach"volunteer activity with my classmates.We wanted to protect the marine environment by picking up plastic waste.Early in the morning,we gathered at the school gate and took a bus to the beach.
The beach was beautiful with golden sand and blue sea,but we were shocked by the garbage scattered everywhere—plastic bags,beverage bottles,food packaging and abandoned fishing nets.We divided into groups of four and started working.I wore gloves and picked up plastic bottles one by one,putting them into designated garbage bags.It was tiring,but every time I saw the area around me get cleaner,I felt more motivated.
At noon,we rested under a big tree and shared our feelings.A local fisherman passing by stopped to talk with us.He told us that marine animals often mistake plastic for food and die.Just last month,he found a dead sea turtle with plastic bags in its stomach.His words made us more determined to protect the beach and marine life.
In the afternoon,when we were about to finish the cleaning work,we noticed a little boy throwing a plastic bag into the sea.We rushed to stop him.The boy looked confused and said,"My mom does this every time.Why can’t I "We patiently explained the harm of plastic pollution to marine animals and the environment.He nodded his head in understanding and offered to help us pick up garbage.Just as we were packing the full garbage bags,a sudden strong wind blew.Our garbage bags fell to the ground,and some garbage was blown into the sea again.

参考范文
Paragraph 1:
We were all disappointed when we saw the garbage being blown into the sea.Without hesitation,we took off our gloves and rushed to catch the floating garbage.The little boy also helped us eagerly,picking up the plastic bags that drifted near the shore.Although the wind was strong,we didn’t give up.After about half an hour,we managed to collect most of the garbage that had been blown away.The boy’s eyes shone with determination,and he said he would tell his mom not to throw garbage into the sea anymore.
Paragraph 2:
When we finally cleaned up all the garbage,the sun was setting.The golden light shone on the clean beach,making it more beautiful than ever.The local fisherman came over and praised us for our persistence.We felt tired but extremely proud.This activity made me realize that environmental protection is not always smooth,but as long as we don’t give up,every small effort can make a difference.I also understood that spreading environmental awareness to more people is as important as cleaning up garbage.

第四部分写作
第一节应用文写作
解题思路步骤
1.审清要求：明确文体为通知，受众是全校学生，核心信息包括活动时间、内容、报名方式、温馨提示，需符合环保主题，词数80左右，格式正确。
2.搭建结构：
开头：点明通知目的（组织校园垃圾分类志愿活动），发出邀请；
中间：依次说明活动时间、具体内容（学习知识、实践分拣、制作海报）、报名方式及截止日期；
结尾：补充温馨提示，呼吁学生参与，落款注明发起方和日期。
3.选用词汇/句式：
核心词汇：garbage sorting（垃圾分类）、volunteer activity（志愿活动）、sign up（报名）、environmental protection posters（环保海报）；
常用句式：“The activity will be held at...on...”“We will first...then...and finally...”“Please sign up at...before...”，保证句式简洁，信息传递高效。
4.检查润色：核对信息是否完整、格式是否正确（通知标题、落款齐全）、语法和拼写是否无误，确保符合词数要求。
第二节读后续写
解题思路步骤
1.梳理原文情节：作者和同学参与“清洁海滩”志愿活动，清理塑料垃圾时遇到一个乱扔塑料袋的小男孩，向他解释塑料污染的危害后，小男孩加入清理队伍，不料一阵大风将装好的垃圾吹入海中。
2.紧扣续写开头：
Paragraph 1开头“看到垃圾被吹入海中，我们都很失望”，可围绕“不放弃，继续清理”展开，加入动作描写（脱下手套、追赶垃圾）、小男孩的帮助、环境描写（风势），体现大家的坚持和环保决心。
Paragraph 2开头“终于清理完所有垃圾时，太阳正在下山”，可补充场景描写（夕阳下的干净海滩）、他人的赞扬（渔民）、作者的感悟（环保虽不易，但小努力有大作用，传播环保意识很重要），使故事完整且升华主题。
3.注重细节描写：加入动作（rushed to catch,picked up）、环境（golden light,clean beach）、语言（小男孩的承诺）等细节，让故事更生动真实。
4.控制词数与逻辑：每段词数约75词，两段内容衔接自然，符合原文语境和人物情感，结尾传递积极的环保启示。
