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。

May 22 marks the annual International Day for Biological Diversity,    1     theme for this year is “From Agreement to Action: Build Back Biodiversity”. Nearly half of the global GDP output is related    2    biological diversity. Nearly 40 percent of the global population makes their living on marine or coastal biodiversity.

China is one of the world’s most biologically     3    (diversity) countries. China is home to the world’s third largest number of higher plant species with 35,000,     4     (account) for the world’s 10 percent of the category. The country also owns 686 species of mammals and     5    largest number of unique mammal species. China has 24.02 percent of    6     (it) territory covered by forest and     7    (top) the fifth globally in terms of forest resource coverage.

From the perspective of the world, however, the numbers of wild animals in Africa and the Asia-Pacific region have dropped 66 percent and 55 percent     8    (respective) due to habitat degradation (恶化), development and pollution, climate change and diseases. The threat that worldwide biological diversity is under is worsening as 41 percent of the world’s amphibians, 26 percent of the mammals and 14 percent of birds are facing extinction.

What are we supposed to do? Don’t eat, purchase wild animals. Reduce using plastic     9     (item). Save water and power. Reduce     10     (consume) of domestic paper. Plant trees and forests.

3 . There are plenty of things you can do to live a greener life, through your day-to-day activities, and most of these apply to anyone.

Save energy. The most effective way to cut down on your carbon emissions (排放) is to save energy in your home. Use energy-efficient light bulbs, turn lights off when they aren’t in use, make sure windows are fully closed, and try to reduce the use of your energy.     1    .

Protect water. Every drop of tap water you use consumes (消耗) energy. Remember, it needs several processes before it reaches your tap. It might just be water, but a lot of fossil fuel is used for processing it.     2    . You can turn the tap off while brushing your teeth, switch to more efficient washers and dryers and collect rainwater for use in your garden.

    3    . If a hybrid car (混合动力车) is not an option at the moment, you can choose other ways. Walk or bike whenever you have to travel a short distance. If you want to have long trips or your work place is too far consider using public transport. You can also take a car with friends or coworkers if that works.

Eat greener food.     4    . But did you know that eating the type of food can make an impact on the environment? Agriculture has a big impact on our planet. Also, the food industry contributes much carbon emissions in the process of shipping their products around the world.     5    . They emit more carbon, use and pollute more water than non-animal food production. When you eat plant-based, seasonal, local, and organic food, you help to protect the environment as well as improve your own health.

A．Use less fuel for transport

B．Create more ways to save costs

C．Eat less to reduce carbon emissions

D．In some places, water itself isn’t enough

E．You’ll save energy and money at the same time

F．Eating is one thing everyone must do in the world

G．Animal products have the biggest impact on the planet

4 . Over the past few years, Reading has made rubbish her thought and medium (媒介), painting landscapes on more than 100 pieces of rubbish that she has found while hiking, climbing or boating through 29 national parks.

Reading grew up with an early appreciation for nature, exploring the nearby forests and coastlines. While studying art at Bowdoin College and seeing the great amounts of waste from her painting and sculpture (雕刻术) classes, she began to seriously consider her footprint as an artist. She thought how she could paint landscapes if she was harming them. Two weeks before her graduation, she changed her theme and began using the rubbish as her canvas (画布).

After teaching and traveling throughout the country, while also picking up rubbish to bring to her studio, Reading began volunteering at Guadalupe Mountains National Park. Then, while in Texas during the summer of 2017, a broken hubcap (车轮毂盖) she picked up by the side of the road gave her a new idea. She began to paint the mountain landscape on the hubcap, held it up in front of the real range and took a photo. It became the first in her ongoing series.

Reading: who sells prints of her work for $110-$ 250, often paints outdoors after boating or hiking 5 or 10 miles into the wilderness, completing her landscapes and photos a few hours later. Sometimes she takes her rubbish to the studio and then hikes the finished product back to take her photos, lining up the painted objects with the natural landscape.

For better or worse, materials for Reading’s chosen medium will never be in short supply. Thus, as for Reading, artistically and environmentally, there is a lifetime of work to be done. She hopes that her works reminds others of that fact.

1. When did Reading start to think about her style of painting?

A．At childhood.	B．At college.
C．After graduation.	D．After teaching throughout the country.

2. What did Reading do with the broken hubcap?

A．She sold it for $110.	B．She used it as her canvas.
C．She recycled it in the factory.	D．She repaired it for the owner.

3. What does Reading want to communicate through her work?

A．Value of rubbish.	B．Choice of work
C．Life experience.	D．Environmental awareness.

6 . Over the past four decades, more than 450 butterfly species have been hit by the falling numbers. In the US alone, the number of monarch butterflies (黑脉金斑蝶) has seen a drop of 80%, from scientists recording millions of them in the 1980s, and only 29,000 in 2020. It’s part of a wider possibility across the insect group. In 2017, scientists in Germany raised alarm bells after finding that insects had fallen by more than 70% in 30 years.

For farmers, monarch butterflies pollinate (授粉) a very large percentage of food crops. It is very important t protect them because their disappearance could have a huge economic influence. Butterflies are also helpful in the coal mine for other insects, as it is easier for them to feel the environmental change. and relatively easy to record.

Leading environmental organizations have been working hard to find new ways of recording the number of butterflies. As of now, there is no long-term data to develop good protection methods. The scientists wanted to address the challenge that long term recording programs worldwide have faced: they are focusing on training locals as insect experts, which requires much money. They came up with a new method to the problem. In Yasuni National Park, they hired park rangers (护林员) who were trained and then carried out recording. The rangers were able to recognize butterflies with an 85% success rate, which is important for these kinds of recording programs to be successful.

Compared with other recording projects, this study represents a long-term solution. “Our method increases the chance of recording in the long term by reducing the money spent on it such as wages,” said lead author Maria Checa. “Furthermore, it also offers opportunities for public organizations to achieve their environmental goals.”

1. How does the author develop the first paragraph?

2. How are butterflies different from other insects in feeling the environmental change?

A．They are quicker.	B．They are lazier.
C．They are slower.	D．They are more inactive.

3. What does the underlined word “address” in paragraph 3 probably mean?

A．Discover.

B．Solve.

C．Invent.

D．Balance.

4. What’s Maria Checa’s attitude towards the new method?

A．Uncaring.

B．Disapproving.

C．Positive.

D．Doubtful.

7 . Food production is a major contributor to climate change. A 2020 study found that, even if emissions from burning fossil fuels ended immediately, current trends in food systems could derail efforts to limit global warming to 2℃ above per-industrial levels.

Some foods —such as red meat —— produce far more greenhouse gases than others. Last year, a UK government survey found that more than half the people in the country want to make more sustainable choices around food. But because many food items contain multiple ingredients, it can be difficult to unravel the environmental impact of one product over another.

To create a rating system that people would find easy to understand, Clark and his colleagues used an algorithm to estimate how much of each ingredient was in thousands of products sold in major UK supermarket chains. The researchers then gave food items an environmental-impact score out of 100—with 100 being the worst—by combining the impacts of the ingredients in 100 grams of each product. They considered several factors, including greenhouse-gas emissions and land use.

The team found that products containing lamb and beef—such as ready-made meat pies—had the most serious environmental impact,scoring up to three times higher than products made with poultry. The lowest-impact foods tended to be made with plants and included bread products, fruits, vegetables,grains and beverages rich in sugar.

Comparing the environmental-impact score with nutritional information, the researchers found that healthier foods tended to have low environmental impacts. There were some notable exceptions:both nuts and seafood had a good nutrition score but relatively high environmental impacts.

There are large differences between foods.If made more user-friendly and widely accessible, food-rating systems could help people to make informed choices about what they eat. When we start making choices, it really improves our health and environment in a substantial way. This sort of study may help us find our way.

1. What was the study finding?

A．Burning fossil fuels will emit greenhouse gas.

B．There will be an end to emissions from burning fossil fuels.

C．Too many ingredients in food will harm your health.

D．Food production is related to climate change.

2. Why did Clark and his colleagues create a rating system?

A．To help the people understand the environmental impact of food product.

B．To calculate the profits earned by major UK supermarket chains.

C．To assess the service provided by major UK supermarket chains.

D．To show the nutritional information of food products in the supermarkets.

3. Which of the following will be recommended to purchase according to the team?

A．Nuts and seafood.	B．Lamb and beef.
C．Chicken.	D．Fruits and vegetables.

4. What can we learn about the food-rating systems from the last paragraph?

A．It has been well received.	B．It still needs to be improved.
C．It is convenient and easy.	D．It is not portable to use.

10 . Oceans hold a lot of mystery, even for people who study them. But it's no mystery why they're in trouble. We've been using them to hide our waste -such as pouring oil, plastic, and poisonous chemicals into them for decades. We've over exploited (剥削) many fish stocks to levels so low that they can no longer be harvested.

Oceans are also a primary source of protein for millions of people worldwide. If we want to continue to enjoy what oceans provide, we need to do everything we can to protect them and the life they support. We should ensure the seafood we eat is sustainable.

Of course, not everyone is lucky enough to be able to catch their own fish, which means having sustainable options at the store is critical. As public and companies awareness about the risks caused by overfishing and uncontrolled sea farming expansion have grown, food tradesmen in Canada have developed sustainable seafood policies and commitments.

Seafood Progress, an online resource, is designed to help provide rewards to tradesmen and information to seafood lovers. It makes it easier for consumers in Canada to find out tradesmen's policies on sourcing sustainable seafood, whether they're sticking to those policies and how they're performing compared to their peers.

But tradesmen must do more to ensure their seafood products are environmentally sustainable and socially responsible. This means expanding the scope of their commitments to cover all seafood products they sell, in all their stores. It also requires continuing to work with suppliers and producers to improve practices and make sure the sustainable seafood supply meets consumer demand.

It's no mystery that if we want to continue to eat fish, we must do it responsibly. Seafood Progress has invited seafood tradesmen, suppliers and consumers to join in pushing to this goal.

1. What's the cause of oceans' being in trouble according to paragraph 1?

A．The ever-changing of the global climate.

B．The mystery that people haven't studied.

C．The over exploitation and use of the oceans.

D．The continuous decrease of fish stocks.

2. What can Seafood Progress do for consumers?

A．Provide rewards to them.

B．Urge them to stick to policies.

C．Provide them with enough seafood.

D．Let them know about tradesmen's policies.

3. What does the underlined word “scope” in paragraph 5 mean?

A．Range	B．Chance
C．Risk.	D．Rate.

4. How can seafood be sustainable?

A．Through expanding seafood production.

B．By protecting all the tradesmen's profit.

C．By joint efforts of people involved in seafood.

D．By making policies to control seafood consumers.
