Location:The camp will be held in the beautiful mountainous area of Green Valley,far away from the city.The location provides a perfect natural setting for our environmental activities.
Duration:From July 10th to July 20th,2026.
Activities:
Lectures by Experts:We have invited top environmental scientists and researchers.They will give lectures on topics like climate change,wildlife protection,and sustainable development.
Field Trips:Participants will go on exciting field trips.We’ll visit a local nature reserve to observe different species of plants and animals in their natural habitats.Also,there will be a trip to a wastewater treatment plant to learn about water purification processes.
Hands-on Projects:Campers will work on practical environmental projects.One of the projects is to build a small-scale solar-powered water-pumping system for a local community garden.This will help the garden save energy and water.
Group Discussions:There will be daily group discussions.Campers from different backgrounds will share their ideas and experiences on environmental protection.These discussions will encourage critical thinking and new perspectives.

B(2025·浙江模拟)
Through evolution,animals have developed numerous ways to protect themselves from predators(捕食者).Turtles hide in their shells,and skunks(臭鼬) use smelly liquid.But these defenses don’t work against cars.Environmental journalist Ben Goldfarb explains,“When facing a car,these defenses are useless—or even harmful.Staying still is the worst choice.Roadkill is a serious threat to wildlife.”
Roads also act as barriers,preventing animals from moving freely.The constant traffic on highways creates what scientists call a “moving fence”—a wall of vehicles that animals avoid crossing.While we often see dead animals like deer or squirrels on roads,we don’t see the ones that never try to cross.This isolation can harm animal populations more than roadkill itself.
Chemicals from roads also damage the environment.Every year,the US uses 20 million tons of road salt to melt ice,which pollutes nearby soil and plants.Cars release metals like zinc and copper,and tires leave behind microplastics.These pollutants make roadsides dangerous for creatures like monarch butterflies,even though these areas could otherwise be good habitats.
Roadsides sometimes attract animals with food like flowers or berries,but this becomes an “ecological trap”.Animals are drawn to these resources,only to face the danger of traffic.
Interestingly,when traffic decreases,animals quickly adapt.Researchers in the Bay Area found that when cars disappeared for months,white-crowned sparrows—small songbirds—started singing more complex and varied songs.Without traffic noise,they no longer needed to “shout” and could return to their natural behaviours.This shows how much roads affect wildlife—but also how adaptable animals can be.
Despite these challenges,Goldfarb says,certain species have made remarkable adaptations.He notes that Chicago’s urban foxes are said to look both ways before crossing the street.“We think about roads as these forces that are universally or exclusively harmful to animals,and certainly they’re incredibly destructive,” he says.“But wildlife is also impressively adaptive and clever and animals are finding ways to make a living in our midst.”
4.How does the author start the text in the first paragraph
A.By stating a reason.
B.By providing statistics.
C.By defining a concept.
D.By giving examples.
5.What harmful impact do roads have on wildlife
A.Less food supply.
B.Restricted movement.
C.Increased predators.
D.Species extinction.
6.What can we infer from Goldfarb’s words in the last paragraph
A.Roads are not truly harmful to wildlife.
B.Urban foxes seldom get hit by vehicles.
C.Animals adapt cleverly to dangerous roads.
D.Wildlife protection deserves highest attention.
7.What is the author’s purpose in writing this passage
A.To advocate reducing traffic.
B.To preserve wildlife diversity.
C.To analyse roads’ effects on wildlife.
D.To highlight roadkill danger to animals.

Green roofs have been around for thousands of years,long before modern housing was developed.From the simple grass-covered roofs above caves to the famous Hanging Gardens of Babylon,they remained an important part of architecture. 8  They bring enormous environmental benefits and offer solutions to some pressing ecological challenges of our time.
In the design of a green roof,there are key factors that count.The first step is to install(安装) a protective layer over the roof to prevent water damage. 9  It’s essential to choose high-quality materials,as once the green roof is completed and the building is in use,replacing the protective layer becomes difficult and expensive.
Next,a drainage(排水) layer,which is often made of pebbles or a special mat,is placed on top.It helps water flow off the roof instead of pooling on it.Then,a growing medium,like soil or other similar materials,is spread over the drainage layer. 10 
Now it’s time to choose plants for the roof.Some plants have shallow root systems and don’t need much water. 11  Sedum and chives are good examples of such plants.They are not only water-efficient but tough and long-lasting.
 12  It’s important to think about your budget.On average,it costs $25 to $30 per square foot to install a green roof.This doesn’t include the cost of installing or repairing the normal roof underneath.And there is labour cost to cover.If a traditional roof costs $30 per square foot,installing a green roof could easily double that expense.
A.This is where the plants will grow.
B.However,green roofs come at a high cost.
C.Today,green roofs are gaining more attention.
D.These features make them ideal for green roofs.
E.As a result,they led to the popularity of green roofs.
F.Green roof materials can range from grass to solar panels.
G.The layer also stops plant roots growing into the roof structure.
