1 . The newly-elected president of Brazil, Jair Bolsonaro says that his country should withdraw (退出) from the 2015 Paris Agreement, and that Brazil’s rainforest protections are standing in the way of economic success. During the election campaign, he promised to ease protections for areas of the Brazilian Amazon set aside for native people and wildlife. Are Brazil’s rainforests in danger?

The Amazon, the world’s largest rainforest, is called “the lungs of the planet.” Each tree takes in and stores carbon dioxide from the air around it. Billions of trees pull up water through their roots and release water vapor into the air, forming tiny drops of water. The Amazon creates 30 to 50 percent of its own rainfall. Carlos Nobre, a climate scientist, says that it is almost impossible to say Just how important the rainforest is to the planet’s living systems.

Some of Bolsonaro’s support comes from business and farming groups. One supporter, Luiz Carlos, noted that farmers “are not invaders, they are producers.” He blamed the past government for supporting rainforest protections at the cost of farmers. “Brazil,” he said, “will be the biggest farming nation on Earth during Bolsonaro’s years.”

Paulo Artaxo, a professor of environmental physics at the University of Sao Paulo, says that if Bolsonaro keeps his campaign promises, then “deforestation of the Amazon will probably increase quickly — and the effects will be felt everywhere on the planet.”

Other scientists warn that if the Amazon and other tropical rainforests lose too many trees, this could affect rainfall in other areas. Without enough trees to support the rainfall, the longer and bigger dry season could turn more than half of the rainforest into a tropical grassland.

3 . Royal Dutch Shell is launching a $ 300 million forestry program, at a time when an increasing number of oil companies are putting money in carbon offset (碳补偿) plans to meet climate goals. The company will spend the money over the next three years on projects to store carbon, including large forests in the Netherlands and Spain, and will start offering motorists the option of purchasing carbon offsets when they buy petrol at the pump.

The executives of the company explained that these carbon offset projects were a new business opportunity for Shell, as well as a way to meet its climate targets. “We believe that over time we will be building a business, because these carbon credits will become more valuable as carbon becomes more limited,” they said. Shell recently decided to cut its net carbon footprint by 2-3 percent in five years, which includes emissions from the products it sells. The company plans to produce carbon credits from the forestry projects, then sell these credits on to customers buying its oil and gas products , or apply the credits to its own operations to lower its carbon footprint.

Plants absorb carbon dioxide as they grow and restoring forests and other natural areas is considered one of the simplest ways to store carbon. However, the voluntary market for carbon credits based on forestry projects has its critics, as projects in developing countries can be hard to monitor. Shell's move has also been criticized by some environmentalists. They worried that there was a risk of “green wash” when companies invested in forestry projects. “There is an entire debate about whether forestry projects truly reduce emissions or not,” they said, pointing out that planting in one area could cause deforestation(滥伐森林) to another.

Shell said it would rely on the third party to ensure its forest program to meet the Voluntary Carbon Standard and strict biodiversity requirements. Mark Lewis, head of climate change investment research at BNP Paribas, said," Planting trees to offset emissions, as far as it goes, is a step in the right direction.

4 . 阅读下面材料, 在空白处填入适当的内容 (1个单词) 或括号内单词的正确形式。

Ten years ago, Sir Richard Branson launched an exciting challenge. A reward of $25 million would be offered to anyone if he/she     1    (come) up with an achievable and sustainable way to remove greenhouse gases from the air. He thought such an innovation would soon come true, and that    2    (power) people like him would carry out a top-down solution in one fell swoop (一下子).

No such situation appeared, not even with the massive reward. But all is not lost. Branson believed everyone could participate in    3     (save) humanity; it wouldn't be a task for just a few superheroes. It was the spirit    4     inspired Paul Hawken and a network of researchers to come up with the book, Drawdowns.

Drawdown focuses on small, practical steps, not    5    (possible) solutions. Hawken's researchers collected data, information and practical knowledge, creating what is something of an encyclopedia (百科全书) of solutions    6    the climate risk. One section of the book, “Coming Attractions”,     7    (look) at solutions that we are close to getting a handle on, and they are likely to be useful ones for the near future. Not a daydream, in other words,

Just as it says in this book, we can't just build a piece of big equipment    8    (make) the air cleaner. We can make small    9    (contribute) like reducing food waste, changing the lightbulbs to LED, installing solar panels and so on.

We are living in     10    interconnected world, so we need to think about the community, about the common interests of many individuals inhabiting a single planet.

6 . When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on earth. We have polluted the deepest oceans with plastic rubbish. “And now”, CNN says, “It's the Arctic's turn.”

German scientists have recently found microplastics (微塑料) in Arctic snow. Microplastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1800 pieces of microplastics per liter of snow.

How is plastic pollution reaching the Arctic? According to scientists, “It's clear that most of the microplastics in the snow come from the air.” They fall off the plastic objects and are moved by the wind, just like dust. They mix with ice in the air and fall to the ground as snow. Finding these plastics in Arctic snow means that we may breathe them in.

Are they bad for us? Scientists cannot answer this question for now, according to the WHO. We do know that our bodies cannot take in “large” pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health. What's more, earlier studies have shown that microplastics may contribute to lung cancer risk.

Microplastics have also been found in rivers and oceans around the world. Earlier research has found that they flow over long distances and into our oceans, hurting ecosystems along the way. They start in our wastewater, then flow into rivers and out to the sea, where they are eaten by sea animals. If people then eat these animals, it means that we're eating the plastic as well.

8 . In the 1990s, when an area of Brazilian rainforest in Amazon region, the size of Belgium, was cut down every year, Brazil was the world's environmental villain（反派角色）. Now, the Amazon ought to be the image of what is going right. Government figures show that deforestation fell by 70% in this region during the past decade. If deforestation had continued at the rate in 2005, an extra 3.2 billion tons of carbon dioxide—equal to a year's emissions from the EU would have been put into the atmosphere. However, Brazil is now the world leader in dealing with climate change.

But how did it break the vicious cycle（恶性循环）? There was no shortcut but a three –stage process including bans, better governance in frontier areas and consumer pressure on companies.

The first stage, from the mid-1990s to 2004, the government put its efforts into bans and restrictions. For example, every farm in the Amazon, had to set 80% of the land aside as a forest reserve. But this share was too high to reach. This was the worst period. Soybean prices were high and a vast expansion of soybean farming expanded on the south-eastern border of the rainforest.

During the second stage, from 2005 to 2009, Brazil's president made stopping deforestation a priority（优先事项）, resulting in better co-operation between different bits of the government. The area where farming was banned was increased from a sixth to nearly half of the forest.

The third stage, from 2009, was a test of whether a system of restrictions could survive as soybean expansion continued. The government shifted its focus from farms to counties of each stave. Farmers with me worst deforestation rates were banned from getting cheap credit（贷款）until those rates fell.

Brazil's Amazon policy is a success because it relied on restrictions rather than rewards, which have worked better. Brazil also changed itself into a farming superpower, so the country is possible to get a huge increase in food output without destroying the forest. But now the policies have been successful among commercial farms. Small holders care rather less about the law and respond to market pressures, so the government have to persuade them to change their ways. Deforestation has been slowed, but not yet stopped.

1. Brazil is considered to play a leading role in dealing with climate change because________.

A．it has rainforest as large as Belgium

B．it has taken action to reduce deforestation

C．it has cut down too much rainforest

3. What can we infer from the last paragraph?

A．Small farm holders are a headache for the Brazilian government.

B．All the farmers care much about forest protection.

C．Brazil has successfully got rid of deforestation.

D．Both the food output and the forest in Brazil have greatly increased.

4. What can be the best title of the passage?

A．Restrictions Better than Rewards

B．Brazil, the World Leader in Forest

C．Cutting Down on Cutting Down

D．Former Awareness Creating Wonders
