1 . 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.

2 . The band Coldplay has released (发行) a new album called “Everyday Life”. But the group has announced it won’t go on tour until it can figure out how to tour without making the climate worse.

Normally when bands have a new album, they go on tour to promote (推销) the album. They may fly from country to country and drive across countries in buses, performing in concert after concert.

Touring is an important way singers and musicians earn money. But tours are very hard on the environment. Flying is one of the biggest sources of greenhouse gases. During their last tour, the band flew to five different continents and played 122 shows. They traveled with 109 supporting workers, 32 trucks, and 9 bus drivers. Think about the pollution from Coldplay’s flights as well as the trucks, buses and huge amounts of electricity required to power the shows!

It’s hard to keep track of the pollution a band creates while touring, but most of the environmental cost comes from the fans. During their last tour, Coldplay entertained 5.4 million fans, all of whom had to travel to the concerts and bought “merchandise” like T-shirts, CDs and posters. Some bought food and drinks at the concerts, creating tons of plastic waste.

Instead of touring to promote the new album, Coldplay recorded two videos of the band playing their new songs live in Jordan and has put the videos of their performances up for free viewing on YouTube.

Coldplay, one of whose dreams is to have a show with no single-use plastic and have it largely sun-powered, says it won’t tour again until its members work out how to make their tours help instead of hurt. The decision will cost the band a lot of money in the short run, but it could pay off big for the planet.

1. Why is Coldplay’s last tour mentioned twice by the author?

A．To stress the necessity of the tour.

B．To describe Coldplay’s great popularity.

C．To introduce Coldplay’s basic information.

D．To show huge environmental costs of the tour.

2. How did Coldplay promote the new album?

A．By making a tour in Jordan.

B．By distributing free CDs to fans.

C．By posting their performances online.

D．By performing their new songs live on TV.

3. Which of the following best describes Coldplay’s decision to quit tours?

A．Thoughtless.	B．Meaningful.
C．Temporary.	D．Doubtful.

3 . Looking fashionable feels good. However, did you know that doing so could be extremely bad for the planet?

Making clothes requires lots of energy. For example, cotton fields have to be watered. Jeans must be dyed (染色) and then dried. According to scientists, making 1 kilogram of clothes produces 23 kilograms of greenhouse gases on average.

However, clothes are spending less time in shops and at homes than ever. Consumers (消费者) today keep almost every article of clothing only half as long as they did 15 years ago. That causes a large amount of waste.

Some clothing companies and designers have realized this problem. H & M, for example, was the world’s largest buyer of “better cotton” last year. The cotton needs less water to grow. It also requires fewer pesticides (农药). The Swedish brand has also stopped using a chemical that pollutes the environment when making waterproof (防水的) clothes. Nike, meanwhile, has invented a new method of making shoes. It reduces waste by 60 percent compared with traditional cutting and sewing.

More long lasting clothes could help, too. Tom Cridland is a British designer. The clothes that he designs all go through a special treatment. Cridland says they can last more than 30 years.

Unfortunately, not all clothing companies and designers, think they should be responsible for the environment. Some companies do not care about their carbon footprint at all.

What can we do? In some western schools, students are encouraged to fix their jackets and trousers. Clothing companies there send vans to campuses to help them do it. Another solution is to think twice the next time we buy new clothes. Some clothes may not look very fashionable, but they could be good for our planet.

1. According to the passage, making 50 kilograms of clothes produces about        kilograms of greenhouse gases.

A．23.	B．115.
C．230.	D．1,150.

2. What is the difference between “better cotton” and traditional cotton?

A．“Better cotton” can grow without water.

B．“Better cotton” grows faster than traditional cotton.

C．“Better cotton” is more environmentally friendly.

D．“Better cotton” is more productive than traditional cotton.

3. In order to protect the environment, what have some clothing companies and designers been doing?
① Using new material.
② Helping students mend clothes.
③ Measuring their carbon footprint.
④ Designing clothes that can last longer.

A．①②③	B．①②④
C．①③④	D．②③④

4. What does the author advise us to do in order to help protect the environment?

A．To stop buying clothes.

B．To wear fewer clothes at home.

C．To ask clothing companies for help when our clothes are torn.

D．To buy clothes made by companies that care about their carbon footprint.

4 . After living in the city for nearly ten years, my family decided to be more self-sufficient (自给自足). Then we moved into a house in the country, where we met real challenges.

There was no electricity available in the area. The energy is generated by the wind and sun and stored in batteries. When we first moved in, we lost power almost daily. After this happened a few times, we came to realize how often we wasted electricity. Lights, fans and computers were left on when they were not in use. The refrigerator door was left open too long. The cell phone chargers were plugged in all the time. All of this used unnecessary power. We steadily increased our awareness of conversing (节约) power.

No water line is connected to the house. We have two large water tanks. Every weekend after we came here, we carried two smaller tanks to the nearby town and filled them with water, which we carried back and pumped into our big tanks. It didn’t take us long to understand that we had to use less water. We started taking quicker showers, turning off the water while brushing our teeth and collecting the water every time it rained.

In addition, we are also trying to make other changes, including reducing the amount of waste we produce, growing our own organic vegetables, and reusing things that we would normally throw away. These changes not only make sense financially but also give my kids a feeling of satisfaction in doing something good for the planet.

While living far away from civilization has been a big adjustment, there are many benefits. One of the greatest is teaching my kids the importance of conservation. We used to take water, power and gas for granted. Now we have learned to conserve. I hope that once my kids move out of the house, they will keep the habits that they have formed by living here.

1. Why did the family move to the country?

A．To reduce their expenses.

B．To change their way of life.

D．save water

3. What kind of benefit does the writer seem to value most?

A．Children’s awareness of conservation.

B．The good habits of protecting the planet.

C．The determination to take up challenges.

D．The ability to adjust to new environments.

5 . What is eco­fashion? Eco-fashion is about making clothes that take into account the environment, the health of consumers and the working conditions of people in the fashion industry.

    1     Firstly, the production of textiles(纺织品)pollutes the environment heavily. Cotton­planting uses pesticides(杀虫剂)；sheep­farming and wool­cleaning contribute to global warming；Secondly, every stage of clothing production has a significant effect on the environment. They all use a great deal of energy, and some also involve chemicals which evidently do harm to the surroundings.    2    Thirdly, growing consumption levels and our shopping habits further worsen the bad effects. We are now so quick to throw away clothes that have been worn only a couple of times.

    3    To a large degree, it is the fashion producers that really have the power and the responsibility to shape our future. There are numerous ways in which these producers can reduce their ecological footprint, from switching to green energy and reducing energy use, through selecting sustainable (可持续的)materials and choosing local suppliers, to recycle and minimize waste.     4    

There is some concern that eco-friendly fashions are just a trend that we will eventually grow tired of but in fact, more and more people are concerning about this and we can make sure that doesn’t happen.    5    

A．Then, how to solve the problems?

B．They relate directly to our personal health.

C．Because choosing eco­fashion can also contribute to our personal health, though it is mostly done by way of keeping the health of the planet.

D．In addition to this, there is a lot of waste produced in the process, especially in the form of polluted water.

E．The fashion industry has developed quickly.

F．On the other hand, as consumers we can all make contributions by selecting environmentally friendly clothing and reducing clothing consumption.

G．A closer look at the fashion industry points out many problems.

7 . The amount of rubbish that piles on our shore lines is hugely worrying and a growing problem for the planet. It seems like no matter how remote you hike and how high you climb, there’s always a dropped plastic container there waiting for you.

Mariah Reading, an American artist, spends the majority of her time outdoors looking for inspiration for her art, based in nature and our natural surroundings. On noticing the amount of waste filling her natural areas, she decided she had to reflect it in her works.

For her latest project, Mariah is looking at both the problem of wasteful littering and the way that art itself can be wasteful in materials, taking the dropped items that fill her natural spaces and painting them to reflect the place in which they were left.

Applying paint to create her masterpieces, Mariah has collected trash (垃圾) from different mountains and parks. “I’ve been considering my relationship with art and the large amount of waste it can produce,” says Mariah. “I wanted to find ways I can confirm art and its important purpose by working with recycled materials found in landscape environments.”

“Since the 100th anniversary of the National Park Service, I’ve especially appreciated and been inspired by the natural beauty the parks offer, and found how easily we can take these precious places for granted. I seek to gather as much trash as possible, sculpt it into a canvas (画布), and paint the scene where the trash originated onto the trash itself,” says Mariah.

As well as through this project, Mariah has explored nature in her art in various different ways and through exhibitions. Mariah’s work might not solve the litter problem, but it’s just another way that we can get people talking about the problem and the ways we can prevent it from growing any larger.

1. What gave Mariah the idea of the latest project?

A．The beauty of nearby scenery.

B．The rubbish-covered surroundings.

C．The potential security risks of beaches.

D．The high energy consumption of her artworks.

2. What’s the important purpose of Mariah’s art?

A．To keep people from wasting natural resources.

B．To remind people of the litter problem.

C．To encourage people to explore parks.

D．To make full use of rubbish.

3. What is special about Mariah’s new artworks?

A．They are made of oceanic rubbish.

B．They appear in the form of sculpture.

C．They reflect the trash places on trash itself.

D．They’re designed to inspire people’s love for painting.

4. What can be the best title for the text?

A．The Growing Problem of Rubbish

B．Mariah Reading: a Sociable Artist

C．An Artist Turns Waste into Amazing Works

D．Celebrate the 100th Anniversary of the National Park Service

8 . “Plogging” is a new fitness trend (趋势). It is a combination of “jogging” and the Swedish phrase “plocka upp”, meaning “pick up”. It encourages people to stop while out on jogs to pick up litter.     1    .

Started in Sweden around 2016, plogging is now going global.     2    To advocate plogging, Swedish fitness app Lifesum allows people to record their plogging lime and track their plogging activity as part of the workout choices. According to the app, a typical user will bum 288 calories in 30 minutes of plogging, which is more or less the same as what’s burned off while jogging.

Like other fitness trends, there are plenty of plogging pictures and videos online.     3     Ploggers take plastic bags along with them so they can store the collected litter they find along their route (路线). Many ploggers are surprised to see just how much trash is in parks and along running trails. They even show off their bags of trash online.

Plogging is a great way to encourage people to make a difference in their local environment.     4    All you need for it is a bag for trash and it empowers everyone to help create cleaner, greener and more beautiful communities.

    5     Anyone can do it. You can do it by yourself, with n friend or even in a large group. And it is a challenge you can truly feel good about. Why not give it a go?

A．They clearly show what this trend looks like.

B．Plogging is suitable for all ages and fitness levels.

C．If you’re not a runner, biking or walking works too.

D．It is appealing because it is simple and meaningful.

E．More and more runners are turning their jogs into plogs.

F．So it adds the idea of environmental protection to the sport.

G．Plogging isn’t the first fitness trend to connect sports with a good cause.

9 . The outbreak of locusts, an insect that mainly lives in Africa and Asia, is the worst experienced by Kenya in 70 years. The crowds are some three times the size of New York City, eating their way through thousands of acres of crops and animal grassland and destroying livelihoods in the process.

“These hungry things are alarming,” says Keith Cressman, the UN Food and Agriculture Organization's senior locust forecasting officer. "A crowd the size of Manhattan can, in a single day, eat the same amount of food as everyone in New York and California combined."

Desert locusts are infamous for their ability to breed(繁育)rapidly in large numbers every three months. And with some help from the wind, they can travel as much as 80 miles a day. Most years, the insects stay in African deserts. However, under the right environmental conditions, they can multiply quickly, spread as much as 400 times every six months and cause extensive destruction if left unchecked.

“The insect has the ability to take advantage of good conditions.” Cressman says.

The "good conditions" the scientist is referring to began in mid-2018 when a rainstorm from the Indian Ocean struck a remote area of the Arabian Peninsula known as the "Empty Quarter". Normally, it would dry out within a short period, killing most of the locust population, which depends on green plants for food. However, in late 2018, a second rainstorm struck the same region. The huge sandy area got wet, which is exactly what desert locusts need to lay their eggs and breed. The extra food supply caused the population to explode for the second time in six months.

Luckily, the locusts, experts say, are easy to control with chemicals. Kenya badly needs equipment and a steady supply of chemicals to effectively wipe out the massive insects. Hopefully, leaders worldwide will recognize the tough situation and contribute generously to control the locust outbreak.

1. What can we infer from what Cressman says in paragraph 2?

A．Little can dull locusts' appetite.

B．Urgent action must be taken against locusts.

C．Overpopulation in big cities leads to food shortages.

D．New York and California should meet challenges together.

2. What is paragraph 3 mainly about?

A．Locusts' living conditions.	B．Locusts' destructive effect.
C．Locusts' daily travel distance.	D．Locusts' super reproductive power.

3. For what purpose does the author mention "good conditions"?

A．To explain immediate causes of the locust outbreak.

B．To remind locals to preserve the environment.

C．To analyze how to prevent locust outbreak.

D．To highlight the strength of two rainstorms.

10 . 阅读下面材料，在空白处填入适当的内容或括号内单词的正确形式。

The way we cook is important. In many countries, the two choices are     1     (nature) gas or electric-powered stoves.

The World Health Organization warns that millions of people     2     (suffer) from indoor air pollution at present time, which results from the use of dangerous     3     (fuel) and cook-stoves in the home.

WHO officials say nearly three billion people are     4     (able) to use clean fuels and technologies for cooking, heating and lighting. As a result, more than seven million people die from exposure to indoor or outdoor air pollution each year. Most of the deaths are in     5     (develop) countries, such as lndia, China and Latin American countries.

WHO officials say opening a window or door     6     (let) out the harmful air will not correct the situation.     7     will only pollute the outdoors.

Nigel Bruce,     8     is a professor of Public Health at the University of Liverpool, says researchers are developing good cook-stoves and other equipment to burn fuels     9     a more efficient way.

But, this is just a start. It is urging developing countries to use     10    (clean) fuels and increase access to cleaner and more modern cooking and heating appliances (用具).
