1 . On the top of millions of homes and offices, affordable and efficient solar panels provide further smaller-scale- electricity during daylight hours. People drive zero-emission (排放) cars that were developed like Audi and BMW which run on hydrogen fuel—created using solar energy which turns waste water into hydrogen and oxygen. Solar energy is potential power in the continuous sunlight of space.
The idea of solar power and its potential to be Earth’s giant power source has roots way back before the threat of climate change and using up petrol. The first idea of solar energy was developed back in 1883, when writer Isaac Asimov published a 1941 story, describing a space station beaming down vast amounts of solar energy using microwave beams. US scientist Peter Glaser drew up plans in 1968 to make Asimov’s dreams a reality, only to be stopped by the technological limitations of the time.
But technologies for a solar-powered world are here today, quieting critics who claim global solar power will never overcome issues over long-distance transmission from sunny to less sunny areas, or find storage solutions to allow it to carry on making power when it gets dark.
China, for instance, is already building high-voltage power lines to spread output across the country from quickly developing solar power facilities. The first three months of 2015, alone, saw the Asian giant add 5 gigawatts (千兆瓦) of solar capacity to the entire solar supply of major European nation like France.
Storage solutions already being used worldwide have successfully proved the working of two methods. One uses solar energy to create melt salts, whose heat-keeping qualities allow them to provide the power to drive electricity turbines (涡轮机) through the night. Other solar plants, meanwhile, are using the sun’s rays to compress gas that is then released after dark to drive those turbines.

1. Why does the woman invite the man to the beach?
A.To collect some plastic. | B.To see a whale. | C.To relax. |
A.The community. | B.The government. | C.A recycling company. |
A.Responsible. | B.Lazy. | C.Emotional. |
We all agree that we should recycle more — at home, in the office or when out and about. But for materials to be recycled, they first need to find their way to the right waste stream.
For effective recycling we need effective sorting. And this needs to happen first, in our own home and second, in sorting plants to which waste collected from our doorstep is taken. When you put a plastic bottle in the right recycling bin, you are helping sort recyclables. So the right material can be fed into the right recycling process.
Once recyclable materials are collected from your doorstep, they are further sorted in specialized facilities which ensure the quality of the recycling process.
A.If sorting doesn't happen, recyclable materials can end up in landfills. |
B.This is where different sorting techniques come into play. |
C.In Europe, collection systems vary from country to country. |
D.So citizens need to be aware of their local collection system. |
E.Then they can be collected and taken to the right place for recycling. |
F.The rest, though they could be recycled and reused, were landfilled or burned. |
G.In recent years, Europe has seen a 25% growth in recycling secondary raw materials. |
4 . Is our planet heating up? Are human beings to blame for climate change?
Yes, it has, and even warmer. Greenland was forested between 450,000 and 800,000 years ago, so temperatures were considerably warmer then. There have also been other times of relatively high temperatures.
So why does the concern exist?
It's all about the speed at which temperatures are changing.
What is causing the warming?
IPCC has concluded that human activity is very likely responsible, by increasing the concentra-tions of greenhouse gases and thus the greenhouse effect.
A.Some scientists, however, still disagree. |
B.Has the planet ever been this warm before? |
C.Has human behavior made the planet warm? |
D.Temperatures have been changing all the time. |
E.In the past, temperatures moved up or down gradually. |
F.Mosquitoes have been moving northwards to higher places. |
G.These questions have burst into newspapers, films and popular books. |

6 . In New York, students at 18 schools participate in a program called We Future Cycle. Started by Anna Giordano in 2014, it teaches kids to recycle, compost(堆肥), and reduce food waste.
Lunch areas at the participating schools are equipped with three clearly marked bins – compost, recycle and share. While the first two are common in schools, the third is rare, where kids can put their unwanted drinks, fruits, and even untouched sandwiches. Items in the container are available for any student that wants them. Whatever remains at the end of the day is donated to the food bank. Giordano says the three bins have helped reduce the number of trash bags from an average of 22 to just 2!
To ensure kids adopt similar habits at home, the non-profit has created extensive curriculum to educate families about the importance of sorting waste into the proper streams of recycling, composting, trash and food to donate They also urge parents to have open conversations with their kids about food choices.
But, as we’re all aware, kids aren’t the only ones that waste food - Adults are equally bad, if not worse! To prevent that, Josh Treuhaft founded Salvage Supper club in 2014. The occasionally organized dinners promise people a tasty multi-course meal for a mere $50 USD per person. It is also a plan to save waste because the delicious food is made from vegetables that are past their prime and, therefore, headed for the trash bin.
The other catch? Customers have to eat their meals inside a dumpster(大型垃圾装卸车)! The place, of course, is totally clean. It is just a symbolic gesture. In addition to helping people rethink their actions, Treuhaft also helps them do good by donating part of the profits to non-profits devoted to fighting against food waste.
1. What is the aim of We Future Cycle?A.To collect money and food for poor children. |
B.To educate children to treasure and save food. |
C.To encourage children to share food with others. |
D.To inspire children to learn agriculture knowledge. |
A.Successful. | B.Official. | C.Impractical. | D.World-famous. |
A.It is mainly aimed for adults. |
B.It is founded by Anna Giordano. |
C.It provides free supper for people. |
D.It has enjoyed great success in many schools. |
A.It is money- saving. |
B.People like to be unique. |
C.It can remind people of food waste problem. |
D.A dumpster is much cleaner than a restaurant. |
7 . The streets of Seville, Spain, are lined with over 48,000 attractive orange trees, producing over 16,500 tons of fruit every winter. Though that gives Seville the honor of being Europe's top orange-producing city, the fruit is too sour to be consumed fresh. Some of the produce is used to make jam, but most ends up in landfills. However, that may change soon thanks to an inventive idea to use the oranges to produce clean energy.
The pilot program is being launched by the local government and parks department in cooperation with Emasesa, Seville's water supply division. Juice obtained from 38.6 tons of oranges will be left to ferment (发酵)in an existing biogas facility. The gas released from the fermented liquid will be collected and used to drive a generator to produce clean power. The officials estimate the test run will generate about 1,500 kWh of energy — enough to run one of Emasesa's water purification plants. They say, "It's not just about saving money. The oranges are a problem for the city, and we're producing added value from waste.”
If successful, by 2023, the city hopes to recycle all the oranges and add the electricity generated back to its power system. In trial runs, 1000 kilos of oranges produced 50 kWh of clean energy — enough to satisfy the daily electricity needs of five homes.
“Emasesa is now a role model in Spain for sustainability and the fight against climate change," Espadas Cejas, mayor of Seville, said in the press conference announcing the pilot program. "This project will help us reach our targets for reducing emissions (排 放),energy self-sufficiency, and the circular economy"
The latest attempt is among the many initiatives being carried out across Spain to achieve the country's goal of switching its electricity system to renewable sources by 2050 — and if everything goes according to plan, folly decarbonizing its economy shortly after that.

As global fast-food chains and coffee shops begin phasing out(逐步淘汰) single-use plastic straws, McDonald’s China introduced a “strawless” lid(盖子) for cold beverages at 10 Beijing restaurants on Nov.1,2018.
Like many consumers, Wu Yanmei, a bank clerk in Beijing, had never thought about the impact a simple straw could have on the environment. “Actually, I don’t like using straws, but the cups at fast-food restaurants are all designed for use with a straw,” she said. “I don’t think straws are necessary, so the moves are a good way to raise people’s awareness of not using single-use plastic products.”
However, Jiang Jianguo, a professor of environmental studies at Tsinghua University, said he doubts such activities alone can have a major effect on the global pollution problem.“I don’t think the move by McDonald’s will be a success because previously there were lots of hotels calling for a ban on single-use plastics, but it ended in nothing because businesses compete by trying to make things convenient for consumers, ” he said.
