According to Travel+Leisure,the community group 5 Gyres Institute has developed an app called TrashBlitz that will record trash thrown away in national parks.By noting what kinds of trash are found,the goal is to encourage people to cut down on waste that pollutes the parks. If you’re walking through Yellowstone and find a place with lots of empty bottles or wrappers,you can use the TrashBlitz app to write down where the trash is and any clean-up work you do.This data can then be used to create plans for policy changes,including possible laws and activities to tell visitors to clean up and use things that can be recycled or used again. The group’s 2024 clean-up effort had 259 events at 58 sites,like Olympic National Park.The group collected information as well as reports from volunteers.Based on the data,they found the biggest problem is plastic,which makes up about 77% of all reported trash.Food wrappers are the most common type of plastic litter,but soda bottles,wet wipes,and bottle caps are also usual.Paper is the second most found trash,and metals and fabrics make up the rest. “I found small colorful pieces of plastic in Biscayne National Park,” a volunteer said.“I also saw lots of bags,cups,and takeout boxes broken into tiny pieces along the roads to Everglades National Park.The smaller plastic gets,the more easily it can enter the food chain and the harder it is to remove from nature.” TrashBlitz isn’t just for parks:It works for local clean-ups in communities too.Recent reports include surveys in Los Angeles,Denver,and Austin.Their work is supported by laws:In 2022,the U.S.Department of the Interior said it would not allow people to use single-use plastics in parks. 1.Why was the app invented? A.To help reuse trash in national parks. B.To solve trash problems in national parks. C.To find volunteers to clean national parks. D.To punish those who litter in national parks. 2.What is the data collected by the app used for? A.Educating the public. B.Helping make new rules. C.Creating plans for volunteers. D.Deciding where to put trash. 3.What does the data from the group’s 2024 clean-up effort show? A.The effects and reuse of trash. B.The increase of all kinds of trash. C.The types and percentages of trash. D.The challenges of cleaning up trash. 4.What does the last paragraph say about the app? A.It works well in many places. B.It often surveys user experiences. C.It has improved its system recently. D.It is waiting for laws to recognize it. B (2026山东潍坊高二期中) MIAMI BEACH—South Florida is seeing a wave of new cars,but they won’t add to traffic.That’s because the cars are made of marine-grade(海洋级) concrete and were placed underwater.Over several days late last month,22 life-size cars were lowered into the ocean,several hundred feet off South Beach. The project,called “Concrete Coral”,was organized by the nonprofit REEFLINE,a group known for building underwater sculpture(雕塑) parks as a way to create human-made coral reefs(珊瑚礁).And 2,200 native corals grown in a nearby Miami lab will soon be added to the underwater structure,which will serve as a habitat rich in ocean biodiversity.“I think we are making history here,” said Ximena Caminos,the group’s founder.“It’s a kind of underwater reef that’s teaming up with science,teaming up with art.” Colin Foord,who runs the Miami coral lab,explained that they will soon start the planting process to create a forest of soft corals over the car sculptures.He said,“Nature will take over again,and we’re helping by growing the soft corals.” Foord is confident that the native Gorgon corals will boom because they were grown from survivors of the 2023 marine heat crisis which destroyed vast quantities of Florida corals. Besides the project serving as a testing ground for new coral transplantation,Miami Beach governor Steven Meiner expects it to generate local jobs through ecotourism activities.The nonprofit also offers community education programs,where volunteers can plant corals alongside scientists,and a floating ocean learning center,where participants can gain firsthand experience in coral protection. Caminos acknowledges that the underwater structure won’t fix all the problems—such as climate change and sea level rise—but she said it can serve as a driving force for dialogue about the value of coastal ecosystems. 5.Why were the concrete cars placed underwater? A.To recycle the old cars. B.To promote a new art form. C.To make a home for corals. D.To reduce the traffic pressure. 6.What is the main reason for Foord’s growing the Gorgon corals? A.Its soft nature. B.Its fast reproduction rate. C.Its unique beauty. D.Its strong ability to survive. 7.What does paragraph 4 mainly talk about? A.Future plans of the group. B.Ways to protect corals. C.Chain benefits of the project. D.Solutions to job shortage. 8.What is Caminos’ attitude towards the project? A.Concerned. B.Optimistic. C.Doubtful. D.Unclear. 知识积累卡 一、重点单词 1.wonder n.　　　　　  2.recycle v.　　　　　　　　　　　  3.generate v.　　　　　  二、熟词生义 1.track　本文义:v.　　　　　　　其他义:n.　　　　　　  2.see　本文义:v.　　　　　　　　　　　  其他义:v.　　　　　  三、词块速记 1.piles of trash 　　　　　　　　　　　  2.cut down on waste 　　　　　　　　　　  3.single-use plastics 　　　　　　　　　　  4.add to traffic 　　　　　　　　　　　  5.make history 　　　　　　　　　　　  6.team up with science 　　　　　　　　　  7.gain firsthand experience 　　　　　　　　　　　  四、长难句分析 Foord is confident that the native Gorgon corals will boom because they were grown from survivors of the 2023 marine heat crisis which destroyed vast quantities of Florida corals. 分析:本句是主从复合句。that引导　　　　　　从句;because引导 　　　　　　　　　　　　从句;which引导 　　　　　　从句。  句意:　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 参考答案 Ⅰ.1.heritage　2.habitat　3.substantial　4.decreased　5.collapsed　6.incidents Ⅱ.1.dramatically　2.departure　3.conservation 4.explosion　5.ecological 6.subsequently Ⅲ.Activity 1 1.my appetite for discovery　2.took a turn for the worse 3.decreased rapidly　4.realized I was lost　5.was trapped in a maze of trees 6.had to stay calm　7.spotted a ranger’s cabin in the distance 8.made my way there　9.owed my safety to their presence Activity 2 As I walked aimlessly along the mountain trail,my appetite for discovery led me deeper into the wilderness.However,the weather took a turn for the worse.Temperatures decreased rapidly,and a thick fog rolled in.Before long,I realized I was lost.Every path looked the same,and I was trapped in a maze of trees.Anxiety set in,but I knew I had to stay calm.
