1 . When the sand began kicking up and hitting our faces, I started to worry that maybe we had made a mistake.

That afternoon, my dad had stood on the deck（露台）of our home and laughed as our neighbors packed up their cars and headed inland. They left to spend the night in motels or at friends’ homes that were out of range of approaching summer storm.

Challenging the weather that threatened to damp our spirits, we lit a fire on the beach. Dad told jokes and we had a good time. When it was 6:30 p.m., all laughter disappeared. Our eyes were drawn to the sky. A tornado（龙卷风）was headed straight for us! In a flash, we were all on our feet. The wind started screaming and now we were running to the cottage. My mom stopped next to the front door. “Where can we go?” She shouted at my dad.

Most cottages on this part of Lake Michigan had been built without basements. Ours was no exception. The huge windows and the cottage itself wouldn’t offer safety from high wind.

“Follow me!” my dad yelled. We crawled（爬）beneath the deck, pressing ourselves against the foundation of the cottage. Between the deck supports, we watched the approaching storm in silent terror.

My dad shouted, “Hold on!” and something else I couldn’t hear over the screaming wind. I think he was praying. By the time it reached our cottage, it was nothing more than a strong wind. The rest of the storm lasted for an hour and then simply blew away.

“Next time, we’ll stay inland at Grandma’s. Okay?” my dad said.

2 . Major causes of record fires sweeping across the Amazon rainforest this month include the dry season and human activities, according to research institutions and media reports.

The rainforest is typically wet and humid, and the frequency of fire activity usually rise each year since July — the onset of the dry season, and peaks in September and decreases in October as the rainy season approaches.

However, data from the Brazil’s National Institute for Space Research (Inpe) showed that the number of forest fires in Brazil soared by 82 percent from January to August this year from a year ago, and over half of those fires occurred in the Amazon rainforest. A total of 71,497 forest fires were registered in the country in the first eight months of 2019 , up from 39,194 in the same period in 2018, the Inpe said.

Human activities have led to the recent increase of fires, some experts have noted. The view was echoed by many, though they were divided over who actually conducted the activities. On Friday evening, Brazilian President Jair Bolsonaro pledged “zero tolerance” of environmental crimes, adding that the Armed Forces troops and resources will be mobilized from Saturday to help put out the fires.

Earlier this week, Bolsonaro blamed non-governmental organizations for increasing wildfires in the Amazon rainforest in the country’s north. His claim was refuted (反驳) by environmentalists, who argued that the surge of fires was a result of increasing deforestation and burning fueled by the governments anti-environmental policy. Alberto Setzer, an Inpe researcher, told local news site G1 that all the fires are results of human activities some accidental while others intentional.

Scientists and environmental groups are worried that the fires will aggravate climate change crisis and threaten biodiversity. The emergency has now transcended (越过) Brazil’s borders , reaching Peruvian, Paraguayan and Bolivian regions.

3 . This season, the bushfires in Australia have burned more than 12.35 million acres of land. At least 25 people have been killed and 2000 homes destroyed. According to the BBC, this is the most casualties(伤亡) from wildfires in the country since 2009. The University of Sydney estimates that 480 million animals have died in South Wales alone.

Zeke Hausfather, an energy systems analyst and climate researcher at Berkeley Earth, said warmer temperatures and extreme weather have made Australia more susceptible to fires and increased the length of the fire season. “The drier conditions combined with record high temperatures in 2019 created main conditions for the disastrous fires. Australia’s fires were worsened by the combination of those two. 2019 was the perfect storm for being the warmest year on record for Australia and the driest year on record for Australia,” Hausfather added on Friday.

Kevin Trenberth, a senior scientist at the US National Center for Atmospheric Research, said warmer ocean temperatures are also contributed to more variable weather around the world. Trenberth believes that global warming contributed to energy imbalances and hot spots in the oceans, which can create a wave in the atmosphere that locks weather patterns in places, causing longer rain events in Indonesia, for example, and at the same time contributing to drought in Australia. He said that once an area experiences drought conditions for two months or more, it increases the risk of fires catching and spreading. Those changing weather patterns due to global warming make drought events longer.

Climate experts stress that climate change is not the only factor in the severity of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled burns and other factors can impact the risk to people and property, such as warning systems and the type of development in a given area. Changing those policies has great potential to limit future damage from wildfires along with changes to how fire management resources are dispatched(派遣).

4 . Clothing rental is a hot new industry and retailers (零售商) are demanding to get on board in hopes of attracting green shopper.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated (调查) this question and concluded that it's not as sustainable as it seems.

Take shipping, for example, which has to go two ways if an item is rented — receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.

She writes, ''An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.''

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene (氯乙烯), a carcinogenic (致癌的) air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.

Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it's so easily accessible. There's something called ''share washing'' that makes people waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as ''a way to share rides and limit ear ownership.'' and yet ''it has been proven to discourage walking,bicycling, and public transportation use.''

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step — that's wearing what is already in the closet.

1. What is Elizabeth Cline's attitude toward clothing rental?

A．Clothing rental is a new fashion.

B．Clothing rental is retailers' preference.

C．Renting clothes is not that eco-friendly.

D．Renting-clothes business is in a dilemma.

5 . When you think of the Arctic, you imagine an icy land of pure white snow, which is considered to be the last really clean place     1    (leave) on Earth. Yet plastic trash has now reached the remote regions of the Arctic and the Alps. A team of     2    (scientist) has discovered large quantities of microplastics(微塑料) — very small pieces of plastic waste — in the Arctic snow. While microplastics have been found in sea-water, drinking water, and even in animals over     3     past several years, this is the first study to show microplastics in snow,     4     indicates it is an airborne pollutant that must be paid attention to.

The researchers state that microplastics in snow suggest that microplastics may be in the air that we     5    (breath). Therefore, it is really important     6    (assess) if microplastics also reach lung tissues.

Previous research has found that they flow over long distances and into our oceans,     7    (damage) ecosystems along the way. They start in our wastewater, when we wash clothes     8     plastic fibers. The wastewater then flows into rivers and out to sea, where they     9    (eat) by sea animals. If people then eat these animals, it means that we’re     10    (probable) eating the plastic as well.

6 . Burning coal to provide energy adds planet-warming carbon dioxide, or CO₂, to Earth’s atmosphere. As the planet heats up, experts warn that simply cutting greenhouse gas emissions (排放) will not be enough to avoid possibly disastrous levels of global warming. CO₂ must also be obliterated from the atmosphere, they say.

Existing experimental machines that remove CO₂ directly from the air are too costly to be widely used. But a new report from the U.S. National Academy of Sciences, Engineering and Medicine says effective carbon-removal technology already exists. It is not costly, or even complex science. It’s forests.

The report explains that planting trees and overseeing forests are cost-effective ways to clean the air. They also work well across large areas. Forests used to cover much of the Appalachian Mountains in the eastern United States. In the state of West Virginia, a kind of mining known as strip mining (露天开采) left the land there bare, without trees. Now experts are working to bring back the forests that once covered much of the state.

West Virginia’s Monongahela National Forest is home to a rare group of trees. They are called virgin (原始的) woods; they have never been touched by humans. Shane Jones, a biologist with the U.S. Forest Service, says the trees there were missed by mistake when the surrounding forest was cut down for wood many years ago. That mistake turned out to be a good thing; red spruce (云杉) forests such as those in the Monongahela are extremely effective at taking CO₂ out of the atmosphere and locking it into the soil.

Experts say, nature offers powerful tools to fight climate change.

A．To prove the place is unsuitable for human survival.

B．To stress planting trees is practical for clean air.

C．To indicate trees are difficult to live on such poor soil.

D．To show people in the state are now living a hard life.

4. What can we know about the red spruce trees?

A．They can only be found in Monongahela National Forest.

B．They were given the name virgin woods for beauty.

C．They were cut down for wood by farmers.

D．They could store carbon dioxide in the soil.

7 . Darshan Karwat is making headlines for having maintained an incredibly plain and continued lifestyle during his student years. The man gave up fast food, new clothes, and even toilet paper, until he got to a point where his trash（垃圾）for an entire year fit in just two plastic bags!

Karwat, who is originally from India, started the trash-free experiment when he lived in Ann Arbor, Michigan, and managed to keep it going for two and a half years. In the first year, he produced only 7.5 pounds of trash, and in the second year, he brought that number down to 6 pounds, which is a mind-blowing 0.4 percent of the 1,500 pounds of yearly trash produced by the average American.

Looking back, Karwat says that his inspiration to start the project came from a radio show The Story, on which he heard of a British couple who lived trash-free.

His trash mostly consisted of a few chip bags, glass milk-bottle caps, fruit stickers, and broken glass. He obviously had to make lots of sacrifices to achieve this – he stopped buying any kind of packaged food including cheeses, only drank milk from recycled glass bottles, and gave up on buying new clothes or stuff for his home – no gadgets, furniture, or even cups. He began carrying his own fork, spoon, plate, and a bowl everywhere he went, just to avoid plastic cutlery（餐具）.

“I needed to change the way I lived, and I had to get creative,” he added. “When a restaurant furnished a napkin-wrapped（包纸的）fork and knife, I asked the server to change them for cutlery without the napkin. I’d remember to say “No straw!” after asking for water and to make sure the veggie（素食者）burger I ordered didn’t come with a wooden pick holding it together. I did what I had to do, and it was awkward.”

10 . A sea turtle named Herman, an octopus called Octavia, and a seal named Lidia all spent this summer at the Smithsonian’ s National Zoo in Washington, D.C. But unlike the zoo’s other residents, they are not real animals. These creatures are actually huge sculptures and they’re made entirely out of plastic trash from the ocean.

These giant artworks, along with 14 others, are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by artist Angela Haseltine Pozzi, works to raise awareness about the problem of plastic pollution in Earth’s oceans.

More than 315 billion pounds of plastic litter the world’s oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. Rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. It often collects in spots called garbage patches, which spread over large areas of the ocean.

Thousands of marine animals — including whales, sea turtles, and fish — die each year from eating or getting stuck in plastic bags and other items. Plastic pieces can also injure coral and kill sea grass.

Washed Ashore and other organizations are working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 3000 miles of beaches. They helped Pozzi create more than 60 sculptures of marine creatures that were harmed by plastic pollution.

The artworks on display at the National Zoo include a 20-foot-long coral reef, a 12-foot-long shark, and a 16-foot-long parrot fish. Each one is made from hundreds of pieces of trash like water bottles and sunglasses.

“These sculptures are a powerful reminder of our personal role and global responsibility in preserving biodiversity on land and in the sea,” says Dennis Kelly, director of the National Zoo.
