1 . 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。

    1     (see) from outer space, Earth is a blue planet, due to the fact that the ocean covers over 70 per cent of its surface. According to a new study published in the journal Science, the ocean plays a great role in     2     (slow) down global warming.     3     The New York Times reported, it is “    4     important buffer(缓冲物) ”. 

The oceans can absorb 93 per cent of the heat trapped by the greenhouse gases which humans release into the atmosphere. And the other 7 per cent     5     (absorb) by the air, land and ice caps, according to an     6     (analyse). 

“If the ocean wasn’t absorbing as much heat, the surface of the land would heat up much     7     (fast) than it is right now,” said professor Malin L. Pinsky at Rutgers University in the US. “In fact, the ocean is saving us from rapid warming right now.” 

However, the ocean itself, as Discover Magazine noted, is heating up 40 per cent faster on average than the United Nations     8    (believe) five years ago. That means if the ocean temperatures increase     9    this speed, the high water temperatures “will kill off marine ecosystems, raise sea levels and make     10     (hurricane) more destructive (破坏性的) ”, The Guardian reported.

3 . In an effort to fight the “throw-away culture” and promote reuse and repair, the city of Berlin has taken the unique step of opening its own secondhand department store.

This isn’t your grandma’s thrift shop (旧货商店). It resells perfectly good items that would otherwise be thrown away. A pun on the German words for “department store” and “conserving house”, B-Wa(h)renhaus sells a wide variety of products. Far from simply selling old items, the electronic goods have been fixed by expert technicians and come with a year’s guarantee. And, to reach more secondhand shoppers, the store was set up right in the middle of the famous Karstadt department store.

With the success of its initial six-month trial run, the city plans to open four more similar operations in other parts of Berlin. By 2030, it hopes to have at least one location in each of Berlin’s 12 districts. Since 2008, city policies and educational campaigns have reduced average annual household waste by about 25 pounds per resident. It also recycles about 49% of its mineral construction waste. Currently, the city estimates that 8% of abandoned electronic goods and 6% of huge items thrown away can actually be reused. The goal is to expand the market for these items beyond the usual bargain hunters and eco-conscious consumers.

“Three years ago, we started collecting all kinds of used goods,” city spokesperson Dorothee Winden said. “There are lots of things that are well-preserved and functioning but aren’t being used anymore. The goal is to give these things a new life with somebody who can use them.” The store also includes an education center to encourage more sustainable lifestyles — and also gave an award to a project that recycles school uniforms, so that parents don’t have to buy new ones every year.

1. Why has Berlin opened its own secondhand department store?

A．To attract more shoppers.	B．To promote recycling.
C．To foster traditional culture.	D．To expand secondhand market.

2. In which aspect is B-Wa(h)renhaus different from the traditional thrift store?

3. What can we infer from Paragraph 3?

A．Berlin currently has 4 second-hand stores in construction.

B．Berlin has been successful in cutting its waste since 2008.

C．It is not easy to make the goal to expand the market a reality.

D．It is estimated that Berlin will be a zero-waste city by 2030.

4. What is the author’s main purpose in writing the text?

A．To introduce Berlin’s new reuse shop operation.

B．To raise people’s awareness of reasonable shopping.

C．To persuade people to become eco-friendly shoppers.

D．To encourage more people to donate to secondhand shops.

4 . Earth Hour is organized by the World Wide Fund for Nature. It's a big event usually at the end of March every year. On this evening, people “go dark”.     1    

It's true that turning off lights for just one hour saves only a small amount of power.    2    On one level, joining in Earth Hour makes people think about the problem of climate change and what we can do in everyday life to protect nature.

But on another level, a large number of people’s acting together sends a powerful message to governments and companies.     3     They begin considering green issues when big decisions.

The logo(标识) of Earth Hour is “60+” .The number 60 is for the 60 minutes of Earth Hour.     4     In fact, people who join in Earth Hour say that taking part makes them want to do more for the environment.

    5     Musicians give concerts by playing acoustic(原声的) instruments instead of electric ones, and using candles instead of electric lights. Celebrity chefs have created special recipes for families to prepare and eat by candlelight. Tree-planting sessions, group walks and runs are also among the options.

A．But this is only the beginning.

B．Earth Hour represents every hour of every day.

C．After all, everyone has to answer for what they have done.

D．Besides turning off the lights, people get involved in other events.

E．It pushes them to take urgent measures by making changes to policies.

F．That is, they switch off all unnecessary lights at the same time for one hour.

G．The plus invites people to continue their action even after Earth Hour is finished.

5 . Global fast-food giant McDonald's announced it would be phasing out (逐步淘汰) plastic straws in China. From June 30, nearly 1,000 stores in Beijing. Shanghai, Guangzhou, and Shenzhen began to phase out plastic straws for both dine-in and take-out, expanding to all stores in China by the end of 2020. Diners would drink cold beverages directly through the new cup cover. The move is expected to reduce plastic waste by about 400 tons a year.

Zhang Jiayin, CEO of McDonald’s China, expressed that McDonald's is devoted to building a “beautiful China”. “We believe that taking advantage of McDonald's influence worldwide. reducing straws can be a huge step for sustainable development. In the past decade or so, we have continued to carry out the green packaging action.” Zhang said, “This movement is playing a positive role in the protection of the ecological environment.”

The move is in keeping with China’s national plan to phase out single-use plastics which came into effect in January of this year, in an effort to combat its growing trash problem.

Among other things, the government carries out a nationwide ban on plastic straws and disposable cutlery (一次性餐具) by the end of 2020, as well as a ban on plastic bags in major cities by the end of 2020, and nationwide by 2022.

Plastic has increasingly played a role in global solid waste, and has choked oceans and rivers as well as landfills. Both companies and volunteers in the past few years have taken it upon themselves to respond to this plastic problem in their own ways.

1. What happened to McDonald’s in 2020?

A．It started to gradually get rid of using plastic straws in China.

B．It banned using plastic package in all stores.

C．It became the first company to ban plastic straws in China.

D．It successfully dealt with China’s trash problem.

2. What does the underlined word “combat” in paragraph 3 mean?

C．Arouse.

D．Fight.

3. What can we know about plastic?

A．It is a kind of poisonous material.	B．It has been solved completely so far.
C．It results in a growing waste problem	D．It should be banned in all fields.

4. What’s the best title for the text?

A．McDonald’s green packaging action	B．Plastic a controversial material in daily use
C．How to control environmental pollution?	D．Devotion to building a beautiful China

6 . Marco Springmann and his colleagues, at the Oxford Martin School's Future of Food Programme, built computer models that predicted what would happen if everyone became vegetarian by 2050. The results indicate that if the world went vegan, the greenhouse gas emissions declines would be around 70%.

In the US, for example, an average family of four emits more greenhouse gases because of the meal they eat than from driving two cars——but it is cars, not steaks, that regularly come up in discussions about global warming.

Food, especially livestock, also takes up a lot of room. 68% of agricultural land in the world is used for livestock. When these lands become grasslands and forests, they would capture carbon dioxide and further ease climate change.

However, if the whole world went vegan, there would be negative effects too. First, it is necessary to keep livestock for environmental purposes. "I'm sitting here in Scotland where the Highlands' environment is very man-made and based largely on grazing by sheep," says Peter Alexander, a researcher in socio-ecological systems modeling at the University of Edinburgh. "If we took all the sheep away, the environment would look different and there would be a potential negative impact on biodiversity. "

Plus, meat is an important part of history , tradition and cultural identity. Numerous groups around the world give livestock gifts at weddings, celebratory dinners such as Christmas with turkey or roast beef.

And nowadays, moderation in meal-eating's frequency and portion size is key to solving these conflicts. "Certain changes would encourage us to make healthier and more environmentally friendly dietary decisions," says Springmann, "like putting a higher price lag on meat and making fresh fruits and vegetables cheaper. "

In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock industry. What is lacking is the will to implement those changes.

1. What can we infer from the underlined sentence in the second paragraph?

A．Driving cars is more dangerous than eating steaks in the US.

B．Our dietary choices affecting climate change is often underestimated.

C．People compare the greenhouse gas emissions of the cars and steaks.

D．Cars affect the global warming more seriously than the steaks.

2. Why does Peter Alexander mention the sheep?

A．To show the important impact of livestock on the environment.

B．To show his work as a researcher in the socio-ecological systems.

C．To encourage people to take all the sheep back for environmental purpose.

D．To point out the negative impact of the sheep on the biodiversity.

3. Which saying can best show the author's attitude to livestock?

A．It is hard to please all.

B．Don't put all your eggs in one basket.

C．One cannnot see the wood for the trees.

D．Everything is a double-edged sword.

4. Where is this text most likely from?

A．A biology textbook.	B．A health magazine.
C．A scientific journal.	D．An educational review.

I want to take an action to put my family on the path to zero waste. First, I'll make sure the water in my house won't be left running when no one is using them and the lights in my room will be turned off when I left. Of course, I'll convince my parents to packing the goods in cloth bags instead plastic bags. Beside, I plan to do at least one environmental volunteer project with my family a week. For example, we can spare a few hour on Saturdays to serve at a restaurant but remind diners not to waste food. I'm surely we will be amazed at what much satisfaction we get from our work.

8 . The milk carton, made from layers of paperboard and plastic first, appeared in 1952 and soon replaced glass bottles. They were far lighter, could be piled and distributed more easily, and more significantly, they were found to have 78 percent less of an impact on the climate than glass bottles. The Tetra Pak cartons, with a layer of aluminum foil(铝箔) that allowed heat –treated milk to remain fresh, followed in 1961.

However, every technology has drawbacks and those of plastics are becoming painfully obvious. Landfills are stuffed with bottles and cartons, and trillions of pieces of plastic float in the world's oceans.

Carton makers are far from the only contributions to the ballooning volumes of packaging waste. In some ways, they're encouraging recycling. However, it is not universal even in Europe, only 47 percent of materials from the 37 billion cartons, made for European countries in 2016 were recycled.

Cartons are also stuck in a broader paradox(悖论): as economy advances, people tend not only to recycle more but also to consume more. Croatia’s overall recycling rate for packaging in 2016 was 55 percent, compared with Germany’s 71 percent, but the average German produced four times as much packaging waste as the average Croatian.

In theory, cartons are fairly recyclable. When pulped （打成浆） in liquid, their various layers are separated into paper, plastic and metal. All of them can then be turned to other uses. In practice, recycling is currently unfeasible for cartoons, because a cotton is carefully bonded and constructed often with a plastic lid and a straw fixed to the side.

This means carton makers need to do more to make their products not only useful but also sustainable. This involves stronger links with recycling factories and waste companies to ensure that containers they pump into the world are returned and reused. In the long term, they face a huge technological challenge to get to what Tetra Pak says is its ultimate aim -- to construct cartons entirely out of renewable materials.

9 . About 12 million tons of plastic wastes are entering the oceans every year. This garbage pollutes the water, kills wildlife and breaks down into small pieces that fish and other creatures eat.

Now a group of Spanish fishermen will receive economic support to catch plastics. It is part of a new project. Carlos Martin is one of the fishermen taking part in the project. He and his partners collect the plastic in the ocean and bring it back to land every week. Martin thinks rivers carry a lot of plastics to the sea. He says his most concern is no more than that the plastics often get caught in the nets, which makes nets not work properly. They take on mud（泥）, causing the nets to break because they weigh so much.

Under the new programs, one million pounds will support ocean cleanup efforts for fishermen like Martin. The money is coming from the European Union and the Catalan government. Sergi Tudela, the General Director of Catalonia Fisheries, is responsible for the cleanup project. He said, "We are hopeful that if we are successful in this project, we can apply it to other areas in the Mediterranean（地中海）."

Government reports show that the amount of plastic wastes washing up along the Spanish coastline has grown by 65 percent in just six years. Fishing equipment makes up a large part of the about 8 to 12 million tons of plastics left in the world's oceans every year.

Martin says the fishing community now understands how big the problem is. He says, "In the past we didn't see it that way. We took the plastic garbage and threw it back into the water. I think that after a few year here we have realized the problem. Nothing is thrown into the water; we collect everything and bring it to shore.

1. What worries Martin most about plastic wastes at the beginning?

A．They pollute the sea environment.

B．They affect the quality and taste of fish.

C．They prevent the fishing nets from working well.

D．They kill wildlife and reduce his fishing amount.

2. What does Sergi Tudela probably consider doing?

A．Getting more money to support the project.

B．Getting help from other European countries.

C．Spreading the cleanup project to more places.

D．Praising the European Union for their helping to the oceans.

3. What do Martin's words in the last paragraph imply（暗示）about the fishing community?

A．Its members do a lot of work for free.

B．It has stopped using plastic fishing equipment.

C．It has made positive changes to fight plastic wastes.

D．Its members find people sill throw the garbage carelessly.

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

A．New programs are changing fishermen's life

B．Money is given to Spanish fishermen to clean up oceans

C．Traditional fishing equipment causes a lot of plastic wastes

D．Spanish fishermen are encouraging people to clean up oceans

10 . Micro-plastics have occupied almost every part of the planet today, including the most distant reaches.

The Arctic is far from clean, though it s rarely stepped in by visitors. Melanie Bergmann, a marine ecologist (海洋生态学家) and her colleagues had been studying plastics on the Arctic seafloor since 2002. In deep sea, they found about 6,0000 particles (微粒) in every 2.2 pounds of mud. In sea ice, there were as much as 12,000 pieces per 34 ounces of melted ice.

Scientists measured micro-plastics in snow from this distant location and found a lot, which could only have caught rides on the wind. The study raises concerns about the pollution that micro-plastics brought to the air, bringing a health risk to people and animals that breathe them in. But they are less worried about the threat that breathed-in pollutants have to wildlife than about polluted snow going into water.

The science on the health effects of micro-plastics is still going on.“For human health, we now now very little," says micro-plastics researcher Chelsea Rochman, “There is a lot of concern. For wildlife, we know that micro-plastics may go into every level of the food chain." Laboratory studies find some physical and chemical effects from micro-plastics, but the findings vary by the plastic type, shape experiments will be carried out soon with use of equipment if financial support approves."

Even worse is the threat from airborne micro-plastics in the area---too small to be noticed and may actually enter cells. Research on that also has been done and it could be a bigger problem, according to Rochman.

1. What can you learn from the data in Paragraph 2?

A．Visitors rarely step into the Arctic.

B．Micro-plastics threaten the human beings.

C．Micro- plastics are everywhere in the world.

D．The Arctic suffers serious micro-plastics pollution.

2. What makes the scientists worry most?

A．Wildlife's threat by micro-pollutants.

B．Human beings breathing micro-plastics in.

C．Micro-plastics entering the water ecosystem.

D．Micro-plastics pollution worsening global warming.

3. What will the following paragraphs talk about?

A．Damage of micro-plastics to health.

B．Appeals for environmental protection.

C．Findings about airborne micro-plastics in the Arctic.

D．Measures to solve micro-plastics pollution.

4. In which section of a newspaper may this text appear?
