1 . THE GLOBAL WASTE TRADE IS ESSENTIALLY BROKEN

Cut into hillside in northern Malaysia stands a large, open-air warehouse. This is a recycling factory, which opened last November. On a very hot afternoon in January, Shahid Ali was working his very first week on the job. He stood knee-deep in soggy, white bits of plastic. Around him, more bits floated of the conveyor belt and fell to the ground like snowflakes.

Hour after hour, Ali sorts through the plastic jumble moving down the belt, picking out pieces that look off-color or soiled-rejects (废品) in the recycling process. Though it looks like backbreaking work, Ali says it is a great improvement over his previous job, folding bed-sheets in a nearby textile factory, for much lower pay. Now, if he eats simply, he can save money from his wages of just over $l an hour and send $250 a month to his parents and six brothers and sisters in Peshawar, Pakistan, 2,700 miles away, “As soon as I heard about this work, I asked for a job,” says Ali, 24, a bearded man with glasses and an easy smile. Still, he’s working 12 hours a day, seven days a week. “If I take a day off, I lose a day’s wages,” he says.

In the warehouse, hundreds of bags are stacked more than 60 feet high-each stuffed with plastic wrappers and bags thrown away weeks earlier by their original users in California. The fact that the waste has traveled to this distant corner of the planet in the first place shows how badly the global recycling economy has failed to keep pace with humanity’s plastics addiction. This is an ecosystem that is deeply dysfunctional, if not on the point of collapse: About 90% of the millions of tons of plastic the world produces every year will eventually end up not recycled, but burned, buried, or dumped.

Plastic recycling enjoys ever-wider support among consumers: Putting yogurt containers and juice bottles in a blue bin is an eco-friendly act of faith in millions of households. But faith goes only so far. The tidal wave of plastic items that enters the recycling stream each year is increasingly likely to fall right back out again, casualties of a broken market. Many products that consumers believe (and industries claim) are “recyclable" are in reality not, because of hard economics. With oil and gas prices near 20-year lows, so-called virgin plastic, a product of petroleum feed-stocks, is now far cheaper and easier to obtain than recycled material. That unforeseen shift has yanked the financial rug out from under what was until recently a practical recycling industry. “The global waste trade is essentially broken,” says the head of the global plastics campaign at Greenpeace. “We are sitting on vast amounts of plastic with nowhere to send it and nothing to do with it.”

3 . The Amazon is warming three times faster than the global average

It is perhaps the most ironic symbol of the life on our planet. The Amazon is the world’s largest and most bio-diverse tropical rainforest and a huge trap for carbon dioxide. The harms of _________ in this vital resource are old news. But now, the time on the clock is running out. It seems that the world’s biggest rainforest is about to turn into the world’s biggest environmental _________. “We are about to collapse,” says Luciana Gati at Brazil’s National Institute for Space Research. “We are in a(n) _________, we need action now.”

Gati has spent years _________ the Amazon from the air. She believes we are as little as five years from a point of no return, where rainforest begins to turn into dry land. It is also the point at which billions of tons of carbon would be _________ into the atmosphere. “It’s a nightmare,” she says.

That nightmare situation is the well-known Amazon _________ point, where the ecosystem can no longer cope with the damage of the forest cutting. Like a domino game, one brick falling will _________ the whole tower to collapse in a heap.

Warnings that this is approaching have now taken on extreme urgency. The rate of deforestation has increased sharply and is fast approaching the theoretical _________. In September, a group of more than 200 experts, including Gatti, released an assessment of the situation. The conclusion: we are on the _________ of disaster.

Scientists first began to seriously worry about a potential Amazon tipping point in about 2000, when some studies warned that a combination of climate change and deforestation could cause the rainforest to __________.

A few years later, a team of Brazilian scientists put numbers on it. They __________ that in central, southern and eastern parts of the Amazon, a loss of 40% of the forest cover from pre-industrial levels, or 3°C warming would reduce rainfall so much that the rest of the forest would die of __________ and turn into a dry land in less than a decade.

The scientists have since __________ that prediction, partly due to the global warming that has happened since 2000. The Amazon is already 1.2°C warmer than it was in pre-industrial times and is warming three times faster than the global __________. At that rate of warming, between 20 and 25% deforestation would be enough to dry up the land and destroy the Amazon completely.

“Either way, we would be wise not to exceed 20%”, says a scientist, “for the commonsense reason that there is no point in __________   the precise point of limit by tipping it.”

Kangaroos can “talk” to us

Kangaroos can “talk” to people, according to a new study. The report is the first research of its kind to be done on marsupials—a type of creature whose young get carried in skin pockets on their mother’s body. It suggests kangaroos are cleverer than previously thought.

Researchers from the University of Roehampton in the UK and the University of Sydney in Australia tested kangaroos at the Australian Reptile (爬行动物) Park, Wildlife Sydney Zoo and Kangaroo Protection Co-operative. The scientists put food in a box that the kangaroos could not open, and waited to see what the animals would do. Rather than giving up, 10 out of the 11 kangaroos actively looked at the person who had put the food in the box and then looked at the box. The researchers said this could be interpreted as the kangaroos requesting help to open the container.

Dr Alexandra Green, a co-author of the study, told The Guardian newspaper that some of the kangaroos actually approached the person and started scratching (挠) and sniffing (嗅) him, then looked back at the box. “So they were really trying to communicate,” Green said. This behaviour is not uncommon in animals. However, it is usually only seen in domesticated animals, such as pets or farm animals. The lead author of the study, Dr Alan McElligott, explained, “Through this study, we were able to see that communication between creatures can be learnt and that the behaviour of looking at humans to access food is not related to domestication. “Indeed, kangaroos showed a very similar pattern of behaviour we have seen in dogs, horses and even goats, when put to the same test,” he added.

It is hoped that the study will give people a more positive attitude towards kangaroos, which are sometimes seen as harmful creatures that damage farmers’ crops.

5 . Greening the blue

Is there a “natural” way to enhance the potential of the oceans to lock away climate-warming CO₂? Planting more trees on land can help draw down more CO₂ from the atmosphere—the basis of many plans for carbon credits that companies buy to offset their emissions (抵消其排放).     1     Seaweed forests and saltmarshes (盐碱滩) are common examples.

Some regard the potential for this “blue carbon” as huge, although as yet there is no mechanism for integrating it into carbon offsetting plans. John Virdin of Duke University in North Carolina says, “    2    ” He adds, “You have to go out and measure all the carbon that’s there, you have to show that it’s not going to be lost, you have to keep monitoring it.” Virdin and others have proposed extending an existing land-based plan called REDD + (reducing emissions from deforestation and forest degradation) to the ocean, but that is an idea whose ship has yet to sail.

    3     In March, the UK government’s climate adviser, the Climate Change Committee, found that restoring and creating seagrass and saltmarsh ecosystems in the country would only lock away a small amount of CO₂, removing “well below” 1 million tonnes a year. Nonetheless, these are efficient carbon stores according to the committee.     4    

A．Using the oceans as a solution to climate change is hardly a new idea.

B．There is still some doubt about how big the marine offsetting effect might be.

C．It’s really hard to turn blue carbon conservation and restoration into carbon credits that you can sell.

D．Something similar might work in the oceans, by stimulating the growth of marine and coastal ecosystems.

E．And conserving them is important given how much fishing and other activities have degraded them.

F．The big objection to all these plans is the possibility of negative environmental side effects.

6 . After five long years, it appears California’s drought is finally becoming less severe. _______ a recent string of storms, more than a third of the state has now welcomed healthy precipitation (降水量), and California’s snowpack—a(n) _______ source of water as the year progresses—has reached nearly twice its seasonal average in some parts of the Sierra Nevada. That’s a dramatic improvement over last summer, when literally every inch of the state _______ drought conditions. It’s also welcome news for Californians, who have faced a series of water _______ since Governor Jerry Brown declared a state of emergency in early 2014. Farmers have been forced to spend heavily to maintain production.

The state’s water struggles, _______, are far from over. For one, nobody knows for sure how long these rains will last. Although recent precipitation has been _______—in some places more than 80 inches—the accuracy of storm forecasting remains _______ beyond a week. Californians know this all too well: last year, experts projected a “Godzilla” El Niño that would bring record levels of precipitation. It never _______. “Will six weeks from now be wet?” asks Jeanine Jones, California’s interstate water-resources manager. “The skill in that kind of forecasting is just not there.”

_______, a storm slowdown is a very real possibility—and it could leave California without enough water to make it through the dry summer. ________, when that happens, the state has turned to groundwater stored in natural rock formations deep beneath the earth’s surface. But those ________ remain used up after years of drought; restoring them could take years in some places, says Jones.

The quick inrush of water has also created a(n) ________ balancing act for water managers. Keeping surface reservoirs (水库) filled to the edge protects against the possibility of a sudden dry spell, but it also

________ the risk of flooding if and when future storms hit. To that end, water managers opened the Sacramento Weir floodgates earlier this month to pour reservoir water into nearby fields after ________ showed local water levels would likely continue to rise. That’s a calculation that will be made across the state in the coming months.

For now, though, Jones is focused on planning and ensuring the state’s water supply whatever may happen. “We’re halfway through our wettest season, and conditions have been encouraging,” she says. “I would say we’re ________ optimistic.”

7 . “It’s a windy day in Laguna San Ignacio, and the waves seem to come from all directions,” said Sara Clemence in Bloomberg Businessweek. My children and I are riding on a 18-foot boat—small enough that we can reach down into the water if a gray whale swims up alongside. And then we see what we’ve come for: a heart-shaped shower of water and a dark mass rushing below it. As instructed, we splash (溅泼) the water strongly to signal the huge whale, which turns out to be a mother with her weeks-old baby. The baby soon swims beneath our boat, emerges to blow mist in my face, then “lies onto its side like a 2-ton puppy.” Leaning down, I touched its skin gently. “It feels electric. Also, a bit like petting a hard-boiled egg.”

San Ignacio is one of very few places where a person can pet a whale. The whales come each year to the coast of Baja California to give birth and to mate. If you’re lucky, you can “shake hands with a leatheryfin (鳍)” or even “plant a kiss on a cold, salty cheek.” I usually worry about such interactions, because wild creatures can become deeply stressed by human contact. But boat numbers are strictly limited in these protected waters.   And any whale that approaches a boat does so on its own terms. Like that baby whale: “We see him a few times, and he seems to like being petted and splashed.”

So we are two species, connecting through touch, but also through eye contact: “More than once, after nosing around our boat, a young gray turns on its side so one dark, baseball-size eye is looking up at us.” Whalers   used   to   call   gray   whales   “devil   fish”   because   these   magnificent   creatures   turn   violent   when threatened—“or, say, when their babies are harmed.” That makes it feel even more of a blessing when, on our third day there, a large mama whale approaches the boat. “I’m splashing when I feel her nose press up into my hand.” Though she’s “wiser and apparently more alert” than her child, “she still decides to trust us.”

1. Which of the following statements is true according to the passage?

A．The writer was on a whale-touching trip.

B．The writer’s boat went down with a huge wave.

C．The baby whale splashed water all over the writer.

D．The mother whale’s skin felt as hard as a boiled egg.

2. By “does so on its own terms” (in paragraph 2), the writer means whales in San Ignacio are ______.

A．mad with too many visitors	B．ready for hands-on attention
C．restricted in swimming routes	D．enclosed in their safety zones

3. Gray whales got the name of “devil fish” from their ______.

A．strange appearance	B．inborn violence
C．surprisingly enormous size	D．fierceness in danger

4. The writer’s implied purpose in the passage is to ______.

A．popularize the knowledge of whales	B．show admiration for whales’ motherhood
C．share an experience of the sea voyage	D．advocate harmony between man and nature

8 . Nobody expects a natural disaster to strike. Neither does anyone know the impact it can have on life. The following measures can save your life in an emergency.

Typhoon

Typhoons occur in the northwestern Pacific Ocean, particularly in exposed regions like the Caroline Islands, the Philippines, and Japan. The best place to hide during a typhoon is a secure basement or a bathroom with no windows. It is also a good idea to get under a solid piece of furniture to save yourself from a collapsing roof. A must-have device is a battery-powered weather radio, through which you will hear evacuation orders or in other cases, instructions on how to survive in your shelter and learn about the weather situation.

Flood

Floods occur more often than any other natural disaster and change the landscape dramatically. They are usually caused by intense rainfalls lasting for days. Don't try to be the bravest person around and stay in your house. Once you hear the evacuation warning, leave for safer higher grounds with your important papers in a waterproof container.

Avalanche

An avalanche can hit when you are enjoying Alpine skiing in a dreamlike location. It is very fast and disastrous, burying everything in its way under tons of snow. When an avalanche starts, try to move to the side of the slope as fast as you can. There will be more snow in the centre of the flow. To move faster, drop any heavy equipment you have on you. If you get buried in the snow, dig an air pocket to be able to keep breathing. Wait for the rescue team to find you and don't waste your energy shouting or digging frantically. Call out when you hear the team approaching.

Wildfire

Wildfires spread at an amazing speed and destroy everything in their way. If you are caught in a wild fire, use a wet cloth to cover your nose and mouth to ensure that you can breathe. Try to stay upwind of the fire at all times and get close to a pond or river. If there is no water nearby, move to a place which has already burned out and is less likely to spark again. Stay low and cover yourself with wet clothing, a blanket, or soil until the fire passes.

1. Among the four natural disasters, which one requires people to hide indoors?

A．Typhoon

B．Flood

C．Avalanche

D．Wildfire

2. What should those trapped in typhoons probably do when they hear the evacuation orders?

A．get to a basement or windowless bathroom

B．find something solid to hide under

C．leave the place where they are

D．get a torch in case of a blackout

3. Which one of the following statements is TRUE according to the text?

A．Typhoons occur only in the exposed regions in the northwestern Pacific Ocean.

B．Floods cause the most frequent damage among the disasters mentioned.

C．Those who meet with avalanches are advised to call out the minute they’re trapped.

D．Getting clean air matters most in the case of wildfires, despite the difficulty.

Marvelous Mallorca

Located off the southern coast of Spain, the island of Mallorca is often praised as one of the jewels of the Mediterranean. As the Spanish royal family’s preferred summer vacation spot, Mallorca     1     charms visitors with its beautiful villages and mountains covered in orange and lemon trees.

Since it is a(n)     2     small island, Mallorca is best seen by bicycle. The Serra de Tramuntana Mountain range runs along the island’s north-western coast and covers nearly 30 percent of the island’s     3    , which makes it a cyclist’s dream.The     4     roads that cross the tall peaks and rocky cliffs provide some of the most challenging cycling on the island.

However, most of the island’s visitors come to see Mallorca’s splendid coast. Though there are several busy beach resorts built specifically for tourists, you’re better off     5     the 260 beaches around the island on your own. Along the south coast, you’ll find white sands and clear blue waters seemingly made just for diving. In the east, keep an eye out for hidden bays that     6     for peaceful swimming even in high season.

Although Mallorca’s beaches have been its main attraction for many years, more recently, visitors have begun to appreciate the island’s cultural attractions too. Many of Mallorea’s grand old houses and     7     farms are being turned into resorts where visitors can enjoy the relaxed lifestyle of the Mallorcan countryside.

Palma, Mallorca’s lively capital, is also home to many museums, historic buildings, and galleries. Here you’ll be able to     8     paintings by great Spanish master such as Picasso, Dali, and Miro, whose former house in the city’s western district is open to visitors.

As the day     9     down, spend an evening enjoying a freshly caught supper in one of Palma’s oceanfront restaurants while taking in a beautiful Mallorcan sunset. What better way to wrap up your Spanish     10    ?

10 . For the longest time, the predominant description about renewable energy featured awkward technologies, high costs, and burdensome allowance. In the _______ of strict and far-reaching policy changes, the chances for mass adoption seemed slim. Electric vehicles (EVs) simply couldn’t go the distance, and LED lights were unattractive and _______.

But now that these technologies have come of age, a new story is being written. Around the world, businesses, governments, and households are taking advantage of more cost-effective low-carbon technologies.

_______ advances in information technologies (IT), green solutions can be introduced into business operations successfully. And as public support for these technologies has grown, so have the _______ for scaling up to a fully sustainable energy system.

As in any rapid transition, a full understanding of what is happening has _______ events. Many present energy producers find it hard to believe that their world is undergoing a revolutionary change, so they insist that their heavily polluting technologies will remain _______ and necessary for some time to come. Journalists, too, describe the transition with a degree of _______, because it is their job to be suspicious. And politicians and regulators are cautious to adopt a new perspective, _______ they are already struggling to keep up with the pace of change in the energy industry.

To be sure, _______ doesn’t come without setbacks, as the recent growth in energy-related greenhouse-gas (GHG) emissions shows. Yet there is no doubt that the future of energy will be __________ different from the recent past. In fact, the __________ is happening even faster than we think, for example, coal-fired power plants are shutting down faster than ever, and plans for new natural-gas plants are being replaced with more cost-effective wind and solar options. And as the shift toward renewables gains good trends, it will be easier for elected officials to pursue more climate-friendly policies and regulations, thereby creating a(n) __________ circle of change.

As the green transition comes of age, it will offer solutions to all of humanity’s energy needs, placing a clean, prosperous and secure low-carbon future well within reach. Yet even as we hug __________, we must not lose sight of the fact that climate change is speeding up. With GHG emissions __________ to rise, the future of humanity hangs in the balance. One hopes that the shift to __________ energy will tip the scale in our favor.
