2 . A lunch break – it’s an important and often necessary part of our working or school day.   And now we’re spoilt (惯坏) with a lot of places to buy our lunch from, all offering attractive dishes and  sandwiches to eat on the go.

But our appetite for buying our lunchtime fare is not just costing us money, there might be a cost in terms of damaging our planet too. Just grabbing a sandwich, crisps and maybe a cake and coffee can produce at least four items of waste. Paper boxes, cups, wrappers and plastic knives and forks are all part of our disposable (一次性的) feast in addition to the food waste we create. Some experts say throwing away food, which produces methane (甲烷) as it rots, is a bigger cause of climate change than plastics.

But regardless of what causes the most damage, the solution, according to an environmental campaign group called Hubbub, is to eat packed lunches. Tessa Tricks from the group says “People are saying that they are buying food to take out because life has got busier.” And she says people think they are being more efficient; but she argues that it's usually healthier and cheaper to make your own lunch. It means you can eat the things you really want and make the quantity that you actually need.

Of course, preparing your lunch is another thing to fit into your morning scramble (忙乱) of getting ready for work, so if you haven’t got time and you are going to buy lunch, an alternative that Hubbub suggests is to take your own container to a shop and ask them to put your food in it. The idea of using reusable coffee cups for hot drinks and refilling water bottles has already proved successful, so this could be another step in the right direction.

1. What’s the second paragraph mainly about?

A．It costs a lot of money buying lunch.

B．Eating fast food is no good to health.

C．Buying lunch leads to great damage to environment.

D．Experts give suggestions on eating.

2. What’s Hubbub’s suggestion in paragraph 3?

A．Stop eating packed lunches.

B．Eating what you like.

D．Making lunch by yourself.

3. What does the underlined word “this” in the last paragraph mean?

A．Buying lunch.

B．Taking your own container.

C．Using reusable coffee cup.

D．Using refilling water bottles.

4. What will the writer call on others to do?

A．Make a full use of lunch time.

B．Eating properly to keep healthy.

C．Doing what you can to reduce pollution.

D．Giving lunch time eating habit a thought to reduce damage to environment.

3 . In the past five years, about 2.8 billion of school textbooks were sold per year, with total spending of 20 billion yuan ($3 billion), news magazine Outlook Weekly reported, citing data released recently by the National Press and Publication Administration.

If these textbooks are reused for one year, the costs saved can be used to help build around 40,000 Hope Schools in impoverished regions.

The figures show that in 2018, the number of retailed textbooks for primary and secondary schools was 2.93 billion copies, totaling 25.99 billion yuan. If all of them are reused, a total of over 20 billion yuan will be saved per year.

Zhao Dehua, in charge of a company recycling resources, said many college graduates sell the textbooks they have accumulated over the years at an average price of 1 yuan per kilogram. As these textbooks are mostly used to produce recycled paper, the cost is even higher than that of raw paper as the processing procedure of recycled paper is complicated.

At present, free textbooks related to music, art and P.E for the nine-year compulsory education have been reused, but account for less than a fraction of the total number of textbooks. Because of the supply chain obstruction, which increases the costs to match supply with demand, the lack of sound platform and service supporting system for the second-hand textbook trade, most of the textbooks used for compulsory education and higher education end up as waste.

“Every year, second-hand booksellers collect textbooks at a price of about 4,000 yuan a ton, which is more than twice the price of ordinary waste paper, but the number of people who come to collect second-hand books is still few,” Zhao Dehua said.

Besides, the incomplete policies and regulations might bring second-hand book sales platforms and sellers to legal risks.

“Establishing the system of textbook recycling can not only save resources, but also help to cultivate students’ consciousness and sense of responsibility,” said Zhu Pin, deputy head of a school of nine-year compulsory education in Jiangxi province. The school has set up a system for reusing the textbooks and the books are disinfected every week.

4 . The idea of turning recycled plastic bottles into clothing is not new. During the past five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into fabric to deal with plastic pollution. But there’s a problem with this method. Research now shows that microfibers (微纤维) could be the biggest source of plastic in the sea.

Dr. Mark Browne in Santa Barbara, California, has been studying plastic pollution and microfibers for 10 years. He explains that every time synthetic (合成的) clothes go into a washing machine, a large number of plastic fibers fall off. Most washing machines can’t collect these microfibers. So every time the water gets out of a washing machine, microfibers enter the sewer and finally end up in the sea.

In 2011, Browne wrote a paper stating that a single piece of synthetic clothing can produce more than 1,900 fibers per wash. Browne collected samples (样本) from seawater and freshwater sites around the world, and used a special way to examine each sample. He discovered that every single water sample contained microfibers.

This is bad news for a number of reasons. Plastic can cause harm to sea life when eaten. Studies have also shown that plastic can absorb (吸收) other pollutants.

Based on this evidence, it may seem surprising that companies and organizations have chosen to turn plastic waste into clothing as an environmental “solution”. Even though the science has been around for a while, Browne explains that he’s had a difficult time getting companies to listen. When he asked well-known clothing companies to support Benign by Design, his research project that seeks to get clothes that have a bad effect on humans and the environment out of the market, Browne didn’t get a satisfying answer. Only one women’s clothing company, Eileen Fisher, offered Browne funding.

5 .     1       However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场）in good condition.     2     For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    3     Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit.     4     Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces.     5     And best of all, it’s free.

A．It will cost you a lot.

B．This causes major environmental effects.

C．There are many environment-friendly sports.

D．Sports can help you keep fit and get in touch with nature.

E．If you walk regularly, it will be good for your heart and bones.

F．There is no special requirement for you to start your membership.

G．More and more people are concerned about environmental protection.

6 . 阅读下面短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。

Pollution takes away all the beauty of the beaches of Hawaii. I hate to go to the beaches on       1     (sun) weekends and see rubbish bags lying on the sand, cigarette butts(烟头)     2     (bury) in the sand, and soda cans floating in the ocean.

One thing that really annoys me is that I see     3     (tour)who visit Hawaii leave their rubbish on the beaches.

7 . China is known for its long history, rich culture, and cute pandas. It’s also known for some of the worst air quality in the world. But the Asian country is now using a natural weapon against air pollution — trees.

In February, China’s government announced plans to cover at least 32,400 square miles with forest. That is about the size of Ireland. Some 60,000 soldiers will take charge of the tree-planting program. Most of the trees will be planted in Hebei Province. That is an area surrounding China’s capital, Beijing.

Huang Wei is an environmentalist who works for Greenpeace East Asia. She is optimistic about the plan. “Trees act as a sink to absorb carbon dioxide and other pollutants,” she said. Carbon dioxide is a gas that traps the Earth’s heat. It contributes to global warming.

Why is China’s air filled with harmful chemicals? It’s because the country relies on coal-fired power plants. When coal is burned, PM2.5 is produced. PM2.5 is a pollutant. It can cause shortness of breath, heart attacks, and even death.

Just two years ago, pollution levels were so high in Beijing that schools and factories had to close. Huang hopes China’s tree-planting plan will reduce the nation’s suffering from air pollution.

The Chinese government is getting help from others in its drive to make the nation greener. Stefano Boeri is an Italian architect and urban planner. He is leading an effort to plant vertical (垂直的) forests in China.

Boeri’s designs have already taken root in the city of Nanjing, China. That’s where the Nan-jing Green Towers are under construction. The building has two towers. Thousands of trees and hanging plants will grow on the balconies and rooftops.

Boeri says his goal is to design buildings that help the environment and improve air quality. He also hopes to encourage a new generation of green architects.

1. What measure is China taking to improve the air quality according to the passage?

A．Planting more tress.

B．Closing the electricity factories.

C．Forbidding people to burn coal.

D．Designing new buildings.

2. What does Huang Wei think of the new plan?

A．Doubtful.	B．Uncertain.
C．Promising.	D．Ineffective.

3. Which of the following has the closest meaning to “contributes to” in paragraph 3?

A．Adapts to.	B．Results in.
C．Refers to.	D．Concentrates on.

4. Why is Stefano Boeri invited to China to design buildings?

A．Because his design can keep the polluted air outside the house.

B．Because his buildings are built in forest.

C．Because his design is special with two towers.

D．Because his design is environmentally friendly.

8 . ''It can't be done. '' Boyan Slat heard this over and over when he first proposed a way to clean up millions of tons of plastic polluting our oceans.

Slat, who grew up in the city of Delft in the Netherlands, was on a diving trip in Greece three years ago when he was deeply impressed by plastic. ''There were more plastic bags than fish, '' he says. ''That moment I realized it was a huge issue and that environmental issues are really the biggest problems my generation will face. ''

That fall, Slat, then 17, decided to study plastic pollution as part of a high school project. Soon, Slat learned that no one had yet come up with practical way to clean up this massive garbage patches. Most proposed solutions involved ''fishing'' up the plastic using ships equipped with nets—which, as Slat discovered, would likely take more than 1,000 years, cost too much, let off too much sea life along with the trash.

Slat proposed an alternative that mostly avoided these problems: a solar-powered system using a floating plastic tube which will go around the garbage and trap it is 600 meters long. Wind, waves and ocean currents will push the trash toward the tube. A ship will pick up the trash and take it back to the shore. Best of all, Slat predicted his system could clean up the North Pacific Garbage Patch within five to 10 years.

The following, Slat entered the aerospace engineering program at the Delft University of Technology and officially announced his ocean cleanup concept at TEDxDelft. But nothing much moved forward.

Slat organized a team of volunteers and employees for The Ocean Cleanup, which now numbers about 100. In answer to opposition, Slat and his team raised $100,000 from a crowd funding campaign and began testing a 40-meter collecting barrier near the Azores Islands last March.

Over the next three to four years, Slat will push toward a fully operational large-scale project by testing a series of longer and longer barriers.
