1 . A Plastic Ocean is a film to make you think.Think,and then act.We need to take action on our dependence on plastic.We’ve been producing plastic in huge quantities.Drinking bottles,shopping bags and even clothes are made with plastic.    1     What happens to all the rest?This is the question the film A Plastic Ocean answers.

The film begins as a journey to film the largest animal on the planet,the blue whale.But during the journey the filmmakers make the shocking discovery of a huge,thick layer of plastic floating in the Indian Ocean.    2     In total,they visited 20 locations around the world during the four years to make the film.

In the film there are beautiful shots of the seas and marine life.    3     We see how marine species are being killed by all the plastic we are dumping in the ocean.The message about our use of plastic is painfully obvious.

    4     In the second half,the filmmakers look at what we can do to deal with the problem.

They present short-term and long-term solutions.These include avoiding plastic containers and recycling as much as you can.The filmmakers also stress the need for governments to work more on recycling programmes.

We make a shocking amount of plastic.Over 300 million tons of plastic are produced every year,and at least 8 million of those are dumped into the oceans.The results are disastrous,but it isn’t too late to change.    5    

A．This causes them to travel around the world to look at other affected areas.

B．Once you’ve seen the film,you’ll realize it is time to do our part.

C．It has raised public concern all over the world.

D．We live in a world full of plastic,and only a small amount is recycled.

E．But the film doesn’t only present the negative side.

F．In conclusion,we only have one earth to live on.

G．These are contrasted with dumps of plastic rubbish.

4 . A tiny Alaska village has experienced a boom in tourism in recent years as polar bears spend more time on land than on Arctic sea ice.

More than 2,000 people visited the northern Alaska village of Kaktovik in 2018 to see polar bears in the wild. The far north community lies in an area where increasingly higher temperature has sped up the movement of sea ice, the primary habitat (栖息地) of polar bears. As ice has gradually moved to deep water beyond the continental shelf, more bears are remaining on land to look for food.

Polar bears have always been a common sight on sea ice near Kaktovik, but villagers started noticing a change in the mid­1990s. More bears seemed to stay on land, and researchers began taking note of more female bears making homes in the snow on land instead of on the ice to raise their babies. U.S. Fish and Wildlife Service biologists began hearing reports of the increasing number of polar bears in the area in the early 2000s. As more attention was given to the plight (困境) of polar bears about a decade ago, more tourists started heading to Kaktovik.

The village had fewer than 50 visitors annually before 2011, said Jennifer Reed, of the Arctic National Wildlife Refuge. “Today we’re talking about hundreds and hundreds of visitors, many from around the world each year,” Reed said. Most tourists visit in the fall, when bears are forced toward land because sea ice is farthest away from the shore. Bruce Inglangasak, a local hunter who sometimes offers wildlife­ viewing tours, said he's been offering polar bear tours since 2004. Most of his clients (客户) are from China and Europe, as well as from the lower 48 U. S. states. Many tourists stay several days in the village, which has two small hotels. The villagers have benefited a lot from that. In turn, they provide more effective protection for polar bears with financial support from tourism development.

1. What causes more polar bears to stay on land in Kaktovik?

A．Food shortage.	B．Climate change.
C．Habitats’ movement to shore.	D．Their preference for land.

2. How did common people feel about more sight of bears on land?

A．Excited.

B．Puzzled.

C．Concerned.

D．Shocked.

3. What can be inferred from the last paragraph?

A．Hotels in Kaktovik are in demand in autumn.	B．Kaktovik has about 50 visitors annually.
C．Inglangasak makes a living as a tour guide.	D．Tourism affects the balance of nature.

4. Which saying can describe the text?

A．The fittest can survive.	B．After a storm comes a calm.
C．One man’s fault is another man’s lesson.	D．Every coin has two sides.

5 . Off the coast of Formentera, an island, lives seagrass that stretches 15 kilometres. The seagrass, covering several hectares, is made up of a single organism. The grasses are also long-lived, for tens or hundreds of thousands of years. Along with two other kinds of coastal ecosystems—mangrove swamps（红树沼泽）and tidal marshes, seagrass meadows are particularly good at taking carbon dioxide from the air.

This role was highlighted in a report, which was published on March 2nd by UNESCO, on blue carbon—the carbon taken in by Earth's oceanic and coastal ecosystems. In total around 33 billion tons of carbon dioxide, about three-quarters of the world's emissions（排放）in 2019, are locked away in the planet's blue carbon sinks（碳汇）. Research by Carlos Duarte, the report's author and a marine ecologist, has shown that one hectare of seagrass can suck as much carbon dioxide each year as 15 hectares of rainforest.

One reason that blue—carbon ecosystems make such effective sinks is that underwater forests are thicker than the land-based woods. They can also trap floating pieces and organic matter, which settles on the sea floor and can double the amount of carbon stored away. They have another advantage, too. Climate change is leading to more wildfires around the world. As forests burn, their carbon stocks are released back into the atmosphere. Unlike forests on land, blue-carbon ecosystems do not burn.

Blue-carbon ecosystems may not be fired, but they remain affected to other sorts of disasters. In May 2020 hurricane Amphan destroyed 1,200 square kilometres of mangrove forest. A marine（海洋的）heatwave in Australian waters in 2010 and 2011 damaged around one third of the world's largest seagrass meadow in Shark Bay. “Mangrove forests can weaken or control waves and provide natural barriers to storm surges. Protecting and expanding them, then, appears to be a must,” said a marine biologist.

1. What does the second paragraph mainly talk about?

A．The real definition of blue carbon.

B．The special features of the seagrass.

C．The doubt about the blue-carbon ecosystems.

D．The capacity of the blue-carbon ecosystems to store carbon.

2. Why can the blue-carbon ecosystems make such effective sinks?

A．They aren't influenced by natural disasters.

B．They have great ability to absorb carbon.

C．Their carbon stocks are released back.

D．There are more underwater animals.

3. What do the marine biologist's words mean?

A．Mangrove forests are too strong to be broken.

B．Mangrove forests can strengthen waves.

C．Humans should preserve blue-carbon ecosystems.

D．Blue carbon ecosystems can be fired.

4. What is the best title for the text?

A．Plants in the Ocean Are Better at Storing Carbon

B．The Grasses Can Store More Carbon Than Your Expectation

C．Mangrove Forests Can Control Waves Efficiently

D．Blue-Carbon Ecosystem Are Expanding Much Faster

6 . A young Dutch inventor is widening his effort to cleanup floating (浮动的) plastic from the Pacific Ocean. He has developed a floating device (设备) to trap plastic waste moving into rivers before it reaches the oceans.

Boyan Slat was just 18 years old when he invented a system for catching waste in the ocean. He also founded an environmental group called “The Ocean Cleanup”. Its purpose is to develop the system. Last year, Slat showed the next step: a floating device which is called Interceptor. It removes plastic out of rivers. The device is powered by energy from the sun. “The 1,000 rivers are responsible for about 80% of plastic going into the world’s oceans,” said Slat. Three of the machines have already been used. Each machine costs about $775, 660, but the cost might drop as production increases.

Since they were used, the machines have been doing very well, collecting the plastic bottles and all the rubbish in the rivers. According to Slat, it is necessary to close “the tap”, which means preventing more plastic from reaching the ocean in the first place. He wanted to clean them all in the next five years. “This is not going to be easy, but if we do get this done, we could truly make our oceans again, ”said Slat.

The device is designed to be safe in rivers. Its nose is shaped to change directions to keep it away from larger floating things. It works by guiding plastic waste into an opening in the front of the device. The waste is then carried inside the machine where it is dropped into containers. The devices ends a text message to local operators that can come and empty it when it is full.

1. What do we know about Interceptor?

A．It needs solar power to work.	B．It is mainly used in the oceans.
C．It is being under test.	D．It can help sort waste.

2. What does “the tap” refer to in Paragraph 3?

A．The waste.	B．The oceans.
C．The machines.	D．The rivers.

3. What’s the function of the device’s nose?

A．To ensure the device’s safety.	B．To send operators text messages.
C．To empty the waste.	D．To serve as containers.

4. Where is the text most likely from?

A．A novel.	B．A magazine.
C．A diary.	D．A guidebook.

7 . Will you crazy about these newly-built products that are not merely quite useful but also good to the environment? Come and see then!

Eco-friendly Umbrella

Traditional umbrellas come with a fixed surface. Although it is changeable, you cannot replace it easily. This eco-friendly design is more flexible. It is actually only an umbrella skeleton without any surface, which can be folded, so you can put anything such as newspapers, plastic bags or whatever you want to serve as the protecting surface.

Pollution-sensitive Dress

Don’t be caught outside unaware of pollution levels in the air. The pollution-sensitive EPA Dress by Stephanie Sandstrom notices pollution in the air accordingly. This dress—which is actually quite pretty—looks like you pull it from the bottom of the dirty laundry pile when the air is dirty. It might protect your health by advising you to stay indoors for the day, but it won’t do you any favor if you’re meeting with clients.

Eco-friendly Car Racer

Can you image a car racer is so eco-friendly that its tyres are made from potatoes, its body is created from hemp (大麻) and rapeseed oil and it runs on fuel made from wheat and sugar beet? The one seater racing car called Eco One is built by experts from Warwick University, who hope that Eco One will be used by the automotive industry. It is sold at $ 51,000.

Eco-friendly Moss (苔藓) Carpet

Do you know it is said that walking on fresh grass can really increases your blood circulation? The Moss Carpet, created by Nguyen La Chanh, looks at getting the grass to your feet. The mat includes ball moss, island moss and forest moss. The humidity (湿度) of the bathroom ensures that it grows well. And that’s why you need to place it there and not anywhere else.

1. The EPA Dress is designed to ________.

A．discourage people from going out	B．help meet with clients
C．improve people’s appearance	D．inform people of air quality

2. What can we know about Eco One?

A．It can seat one passenger and one driver.

B．It can’t be available for the public at present.

C．It is mainly made from some kinds of plants.

D．It will take the place of the traditional car industry.

3. Where does the text probably come from?

A．A science report.	B．A personal blog.

8 . High on the Qinghai-Tibet plateau lies China’s “Water tower” Sanjiangyuan.     1     The three rivers: the Yellow River, the Yangtze River and Lancang River, provide water for about half the population of China. However, human activities such as overgrazing are putting this ecosystem at risk.

    2     In 2016, the Chinese government established Sanjiangyuan National Park, which was a pilot program for China’s national park system.     3     Due to the progress made in the region, Qinghai held the first National Park Forum on Aug 19.

Sanjiangyuan National Park is a model of eco-protection.     4     For example, Herdsmen have given their grasslands to nature and resettled in urban area. As for wildlife, they are monitored by field conservation stations to keep the environment in good condition.

The idea of a national park system is still new in China, but it must be realized. As President Xi wrote in the congratulatory letter to the forum, “Building an ecological civilization bears great significance in the development and progress of human civilization.” With great efforts, people may one day be able to enjoy themselves in the vast lands of Sanjiangyuan and run freely across the plains alongside nature’s animals.     5    

A．However, we have realized the damage.

B．It’s home to the headwater of China’s three big rivers.

C．Unfortunately, the situation has got worse and worse.

D．It attracts visitors with its fantastic nature beauty and various wildlife.

E．The park has increased the area’s green coverage and attracted more wildlife.

F．Hopefully, the success of Sanjiangyuan will mark the start of a greener future.

G．The local government has different ways of slowing environmental damage.
