1 . Coffee chains create a lot of waste, from disposable take-away cups to the used grounds that are sent to landfills. Starbucks has started to try recyclable alternatives to the disposable cups. But the used coffee is often unnoted.

The world drinks around 2 billion cups of coffee a day, producing 6 million tons of used grounds every year. When they go to landfills, the grounds release greenhouse gases into the atmosphere, contributing to global warming.

UK Bio-bean has found a way to turn that waste into a valuable resource. At Bio-bean, used coffee grounds are processed to remove paper cups or plastic bags, and then passed through a dryer and a further screening process. They are finally processed into the fuel. Coffee Log.

"Coffee is highly calorific and lends itself to being a really fantastic fuel," says May. director of Bio-bean. "They burn about 20% hotter and 20% longer than wood logs do."

While these fuels release greenhouse gases when burned, if they replace other carbon-based fuels. Bio-bean estimates that the recycling process reduces emissions （排放）by 80% compared with sending the grounds to landfills.

Founded in 2013 Bio-bean grew rapidly,   launching coffee collection services across the UK and building the world's first coffee recycling factory only two years later. In 2016 they launched their first product,   Coffee Log, and are now ready to launch their first natural flavouring ingredient into the food and drink industry.

“We've really managed to succeed with our innovation because we've managed to get to scale. What started as a good idea is today the UK's largest recycler of coffee grounds. We are turning 7,000 tons of those grounds per year into the fuel," says George May. "Despite being delayed by the COVID-19, we plan to expand our operation into northwestern Europe within the next five years."

2 . It’s a popular belief that a fish’s memory lasts for only seven seconds. It may seem sad to think that they don’t remember what they’ve eaten or where they’ve been, and they don’t identify you or any of their friends -- every moment in their life would be like seeing the world for the first time.

But don’t be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain kinds of fish can even remember events from as long as 12 days ago. In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again. Researchers used computer software to monitor the fish’s movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively (挑衅地)in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. “If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.

For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

D．African cichlids usually go to a certain area for food.

4. What is the article mainly about?

A．Fish having very bad memories.	B．Fish being smarter than we thought.
C．How fish improve their memory.	D．What we can learn from fish.

3 . Atoms and molecules in the air move constantly.     1     In high-pressure systems, the molecules inside the system move faster than those that surround it. The opposite occurs in low-pressure systems, where the air inside the low is moving more slowly than in the surrounding area.

Air flows around a high-or low-pressure system in much the same way as water swirls (旋涡) around a hole. In the Northern Hemisphere, air that moves into a high-pressure system flows outward in a clockwise pattern. Air flowing upward in a region of low pressure moves counterclockwise.     2    

Air is more dense (密集的) in a region of high pressure, so the air pushes out toward less dense regions. The air mass begins to warm as it goes down, which prevents the formation of clouds. The presence of clouds indicates that rain may be present in the air.     3     In a region of low pressure, the air rises. As it does, the air mass cools and clouds form from the humidity (湿气) inside the air mass.

    4    Once the droplets are heavy enough, they fall to the ground. When temperatures are warm, rain is the result. If temperatures are low? the result is snow. When water droplets fall through relatively warmer or colder air masses on the journey to Earth, the low- pressure system may bring snow or ice.

Rain associated with low-pressure systems holds true in much of the Northern Hemisphere.     5     So in tropical areas, rain association with highs or lows is less predictable.

A．This movement creates air pressure.

B．So we can predict rain from the clouds.

C．But the air pressure changes little in tropical climates.

D．The higher the air pressure is, the faster the winds blow in and outwards.

E．Humidity in the rising air of a low-pressure system becomes water droplets.

F．This swirling air results in winds around or near the high-and low-pressure boundaries.

G．High-pressure systems have light or no clouds, indicating fair weather without rain.

4 . Olympic host cities are generally considered to be equipped with advanced technology and expensive facilities. Now, people can just go there for a little Olympic-level entertainment.

Athens, Greece (1896 and 2004)

Home to the first modern Olympic games in 1896, Athens' history of the Olympic tradition dates back several thousand years. Every four years, the Olympic torch is lit at the Panathenaic Stadium in Athens before beginning its long journey to the new host city. Visitors can walk through the Olympic Velodrome in the Olympic Sports Complex and step back in time at the 50,000-seat stadium.

Barcelona, Spain(1992)

These days Barcelona is among the world's most visitable cities even without Olympic fame, but that isn't always the case. The telecommunications tower built for the games by Spanish architect Calatrava is also an iconic(图像的） device of the city's skyline, and its Olympics stadium- Montjuic Stadium is regularly used to host A-list musical performances like The Rolling Stones, Madonna, and Beyonce.

St Moritz, Switzerland(1924 and 1948)

Appropriately, the town that invented Alpine tourism has hosted the Winter Olympics twice, and continues to make use of its many sports facilities-if you can afford to get there. Stay at the Kulm Hotel for the easiest access to the Kulm Country Club, where guests can skate on the same lake used by mid-century Olympians, or test your courage on the Olympia Bob Run, one of the few places where you can ride a full-speed Olympic bobsled(双人雪橇） on a run constructed entirely of ice.

Sydney, Australia (2000)

The turn-of-the-century Sydney Summer Olympics were named the "Green Games" by the International Olympic Committee (10C) and were designed to introduce a more environmentally conscious way of hosting the event. The structure that best shows Sydney's efforts to be an example of continuing Olympic development is the ANZ Stadium.

1. Where does the host city get the Olympic torch lit?

A．At the Panathenaic Stadium.

B．At the Olympic Sports Complex.

C．At the Montjuic Stadium.

D．At the ANZ Stadium.

2. Who will probably choose to visit St.Moritz?

B．They are thought poorly of by the IOC.

C．They are hosted in an environmentally friendly way.

D．Their design intention is proposed by Sydney authority.

5 . One of the costs of being a lover of old trees is the all-too-frequent loss of a beautiful soul you've grown fond of.Last summer was harder than most for old trees and their human supporters.The spring's nonstop rains flooded soils and caused root systems of many large,old trees to rot in part.Then,when the summer came,trees could not tap deep sources of water that would normally have maintained(维持）them.Many valuable old trees died.

When I volunteered on the Mount Rainier Tree Commission,I heard from many people concerned about their trees.We had little to offer them.That's because public and private urban tree resources and programs were aimed almost entirely at planting trees and not at all maintaining trees.No state or province program that I could find provided any financial resources for maintaining tree health. Small and under resourced cities such as ours were on their own.

This is backward.Scientists are learning that large,old trees are the most valuable,especially in cities.They put on wood fastest and take the most carbon out of the air. They harbor the most wildlife.They can lower summer temperatures by 20 degrees or more.In a recent study,researchers found that Boston would get more benefit from keeping the trees it has alive than from planting new trees.There's reason to think this finding would apply in other cities,too.

Now,our public and private tree programs often ignore old trees until it is too late.As long as we abandon our old trees,planting more is merely to keep pace with growing losses. We want trees to help protect us,but we leave them unprotected.Consider this in the human world:Nobody would send a baby into the world and expect it to just make it. Children need caring for and it's why we have schools and child health-insurance programs.We could get so much more out of our trees if we just put   a little more into them.

1. What does the underlined part in paragraph1 suggest?

6 . Thirteen years ago, the Planet Earth wildlife documentary took us all on an amazing journey. We went from deep rainforests to the bottom of the ocean. Now a new one ,Our Planet, will let us see different animals and the influence of humans on the natural world. The documentary covers 50 countries and areas. It took more than four years to produce it.

With the latest 4K video technology, the show allows people a wonderful new look at nature. "People are given a chance to better get themselves into the lives of the animals” said Fothergill, one of the show s producers.

Besides showing Earth’s beauty, the documentary also talks about the planet's climate conditions. "Our Planet is here to say,' The planet is dying, and we're killing it.’" Fothergill said. In one sad scene, hundreds of walruses(海象)，half-blind when out of the water, fall down a rock and suffer a painful death on the beach below. It shows how the climate conditions have influenced their natural habitat and explains why they've been forced to find the safe place on the rocks.

But the documentary is not all about sadness. It also talks about success stories, such as the ones of tigers. These animals are saved and live happily thanks to international agreements on environmental protection.       

Asking more people to take action in protecting our planet is the final goal of the new documentary. What we do in the next 20 years will decide the future of all life on Earth.

1. What's the documentary Our Planet about?

A．The relationship       between the climate conditions human activities.

B．Different animals and the influence of humans on the natural world.

C．The living conditions of walruses and tigers.

D．The beauty and customs of 50 countries and areas.

2. What's the purpose of the last paragraph?

A．To explain what our goal is in the future.

B．To call for more people to protect our planet.

C．To tell us how the climate conditions influence animals.

D．To introduce international agreements on environmental protection.

3. What can we infer from the passage?

A．It took a lot of time and efforts to make the documentary.

B．The documentary is popular in many countries and areas.

C．We should have a new look at the environmental protection.

D．Our goal in the future is getting along well with animals.

4. Where is the text probably from?

A．A novel

B．A dictionary

C．A storybook

D．A newspaper.

7 . I was watching my kids play on the sidewalk when I looked up and saw a crow sitting on the telephone wire. The crow sat with its head turned to one side， observing us with one friendly black eye.

I'm not a bird expert or a birdwatcher， but crows intrigue me. Since that day， I have become friends with the neighborhood crows， and I've learned a thing or two along the way.

The best way to introduce yourself to a crow is by feeding it. I'm sure there are other ways to go about it， but the easiest and fastest way to a crow's heart is food. Some may argue that a crow is a wild animal and by feeding it， you encourage the unnatural dependence. And to most wildlife， this is an excellent philosophy. But crows and humans have been living side by side for centuries， and researchers like Marzluff and Angell， who wrote In the Company of Crows and Ravens， point to many examples of cultural co﹣evolution （共同进化） between us. It's been a rather symbiotic （共生的） relationship for quite a while.

Certainly， humans' and crows' lives and histories have become closely related. I moved to this neighborhood in this small city 5 years ago. I'm relatively new here， but the crows in my neighborhood may have lived here for many years. They've watched people come and go for years ﹣ people who may have watched them right back.

So anyway， we're neighbors， and feeding is the neighborly thing to do.

1. Which of the following can replace the underlined word "intrigue" in Paragraph 2？

A．Dislike.

B．Interest.

C．Surprise.

D．Frighten.

2. What does the author think is the easiest and fastest way to let the crows like you？

A．To play with them.

B．To make friends with them.

C．To give food to them.

D．To watch them closely.

3. We can infer from Paragraph 3 the purpose of the author is to .

A．develop a philosophy

B．introduce a book

C．correct people's ideas

D．share personal experience

4. What's the author's attitude toward the relationship of man and crows？

A．Positive.

B．Unclear.

C．Doubtful.

D．Indifferent.

8 . Urbanization

Until relatively recently, the vast majority of human beings lived and died without ever seeing a city. The first city was probably founded no more than 5,500 years ago.    1    In fact, nearly everyone lived on farms or in tiny rural（乡村的）villages. It was not until the 20th century that Great Britain became the first urban society in history—a society in which the majority of people live in cities and do not farm for a living.

Britain was only the beginning.    2    The process of urbanization—the migration（迁徙）of people from the countryside to the city—was the result of modernization, which has rapidly transformed how people live and where they live.

In 1900, fewer than 40% of Americans lived in urban areas. Today, over 82% of Americans live in cities. Only about 2% live on farms.    3    

Large cities were impossible until agriculture became industrialized. Even in advanced agricultural societies, it took about ninety-five people on farms to feed five people in cities.    4    Until modern times, those living in cities were mainly the ruling elite（精英）and the servants, laborers and professionals who served them. Cities survived by taxing farmers and were limited in size by the amount of surplus food that the rural population produced and by the ability to move this surplus from farm to city.

Over the past two centuries, the Industrial Revolution has broken this balance between the city and the country.    5    Today, instead of needing ninety-five farmers to feed five city people, one American farmer is able to feed more than a hundred non-farmers.

A．That kept cities very small.

B．The rest live in small towns.

C．The effects of urban living on people should be considered.

D．Soon many other industrial nations became urban societies.

E．But even 200 years ago, only a few people could live in cities.

F．Modernization drew people to the cities and made farmers more productive.

G．Modem cities have destroyed social relations and the health of human beings.

9 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为 150 左右。

Sara Savick remembers one special Easter when she was nine years old. Her parents gave her a baby duckling in a yellow basket.

“Mom said later that she bought the little duck because she felt sorry for it,” recalled Sara. The people at the pet store colored the feathers pink for Easter. Sara named the duck Pinky.

Sara’s mother really didn’t think the baby duck would survive very long. But to her surprise, Pinky grew and got stronger and stronger. Soon, the little duckling was a healthy, hungry duck with white feathers.

“We fed Pinky oatmeal, cooked and uncooked, and small pieces of vegetables,” said Sara. Pinky lived inside the house with Sara and her family. She specially fancied taking baths with Sara. Everyone treated Pinky as a family member.

But just when everything appeared to be perfect, the night of the “talk” came. Sara’s Mom and Dad sat her down, explaining that the best thing for Pinky was to live a normal duck life, with other ducks. It was not natural for ducks to live indoors with a family, her father told her. He added Pinky needed to swim in ponds and do all the same things that ducks in the wild do.

Sara started to cry, knowing what was going to happen. Sara’s parents decided to take Pinky to a park, which was two miles away. There was a pond with a lot of other ducks. Pinky would have the chance to live a natural life and Sara could still visit her.

The big day came, Sara and her parents put Pinky in a box and drove to the park. Sara said that Pinky did not look happy; maybe Pinky was convinced that she was a human, not a duck.
