Sam was a junior high school student. He lived in a community in Charlotte and usually had little exposure to country life. So much of what he knew about plants came from text-books. Sam was a kind-hearted person. He longed for a chance to explore nature and he wanted to do his part to beautify the world.
Finally, the opportunity came. On Arbor Day (植树节), his class organized a trip to a local village to plant trees. Sam was excited about it and couldn’t wait to tell his mom the good news. So the next day, Sam and his mom went to buy some tools for planting trees, including a shovel(铲), a bucket, gloves and so on.
On the day of the event, Sam and his classmates arrived early at the starting point. It was a beautiful day and everyone looked particularly happy. With the tools in hand, Sam got into the bus with everyone else and headed off to their destination.
As soon as they reached the village, all the students were divided into three teams by their teacher. One team was responsible for planting the trees, one team for shovelling the soil and one team for watering the trees. At the teacher’s command, everyone started to do their job.
However, it was the first time that many of the students had taken part in planting trees, so they had no idea about how to start. Of course, Sam was one of them. Fortunately, their teacher was a middle-aged man from the countryside who had some knowledge of planting trees. In order to set an example to the students, the teacher started to plant trees himself. After watching the teacher plant the trees, everyone also became busy. Before long, they planted hundreds of trees. Sam watched very carefully, not wanting to miss any of the details. Finally, Sam learned how to plant trees by himself and felt happy.

She threw her school bag onto the floor and called out, “I’m home!” No answer. The house was silent. It sounded empty, but she knew it wasn’t. Her mum and dad were working upstairs.
Sara got a glass of orange juice, went into the conservatory (玻璃房) and sat down in her favourite chair. The garden was still in the dark afternoon. On one side, her mum’s garden was neat and tidy with boring short grass, boring straight flowerbeds and boring straight paths. But on the other side, Sara’s Nature Garden looked wild and exciting with big dead sunflowers and tall grasses.
“Nobody is interested in me. Mum and dad only think about their work,” she thought sadly.
Then she recalled: One month earlier, she learned in a magazine that many dogs were abandoned because their owners got bored with them; One hour earlier, she saw a cute dog wagging its tail and licking her friend’s face.
Sara knew today was special. Today things were changing. She couldn’t wait any longer. It’s time to talk to her parents.
So Sara got up from her chair and climbed all the way to the loft (阁楼). “Mum, I want a talk.” said Sara. “Just a minute!” Her mum clicked on the keyboard, took off her glasses and turned to her daughter. Sara coughed, took a deep breath, and told her mum that she wanted a dog. “No, Sara. That’s impossible,” her mum said firmly. Sara went to her father but got the same answer. She rushed into her room angrily and slammed the door shut.
Later, Sara’s mum knocked at the door and went in. “Darling, we know this is important to you. You can have a dog if you take the responsibility. But look at your Nature Garden, your school bag, your bedroom! What a mess! Do you think you can take good care of a dog?” said her mum.

_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________When Mary entered the south Pole Penguin Research Lab, she saw her friend Tom gently stroking (轻抚) a penguin in his arms. As children of the lab scientists, Mary and Tom often observed the emperor penguins that were studied to understand how they adapted to extreme temperatures —insights that could aid human survival.
“We’re thirteen, Tom. It’s time to grow up and stop playing with the lab penguins,” said Mary as she started cleaning. “They’re research animals, not pets.”
“But the birds listen to me1” insisted Tom, his breath forming a cloud in the freezing air. “You’re just trying to be a penguin whisperer again,” Mary replied, shaking her head with a gentle smile. The penguins seemed playful as they walked, dove, swam and chased their live fish for sport before eating.
Suddenly , an alarm rang out and red lights flashed , signaling a problem. The kids rushed over to look into it. “It’s colder than before —there’s ice forming on the water,” noted Tom. Though always cold, Mary had never seen ice here before. She checked the habitat monitor and found that the temperature had gone down a lot. “The heater must be broken!”
Mary quickly sent a message to their parents’ research team, who were conducting outdoor studies. With the adults away, the kids would have to deal with the freezing conditions until help arrived.
Time dragged as Mary and Tom anxiously waited. The increasing cold caused them to shake. “I wonder what emperor penguins do in extreme cold, since they stay in the Pole all winter instead of going somewhere warmer,” asked Mary. “They huddle (挤作一团), ” Tom answered. “They huddle together tightly so that the birds in the middle will be warm enough.” “What about the ones on the edge?” Mary asked. “They push their way towards the center, and then move back out to the edge, and struggle back again. Scientists in the early 21st century recorded it.” He replied as he stared at the large crowd of the penguins in the lab.

My mother was in great pain and wished to visit specialists in London. My father reluctantly had to sell our property in Queensland. The day before we boarded the ship, Father unwillingly said goodbye to his five-year-old cattle dog, Spider, who was loved by us all. Father’s friend Sandy was to be his guardian while we were overseas, as he had been getting to know Spider for many weeks.
Six weeks later, an airletter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. Sandy had advertised constantly on ABC and other regional newspapers. Despite many “sightings”, the dog was never found. It seems Spider just kept running and searching for us. As he was cattle dog, my father thought he would shoe or dingo-trapped, because of his appearance. But our family thought that Father held a secrets hope that Spider was still alive.
We sailed back to Australia two years later and re-established our home. My father immediately began his own search for Spider. One cold winter’s Saturday morning eight months after our return, my father had a call from an elderly lady living on her own on the outskirts of the town. As she told my father on the telephone, it was “just glimpses of a dingo-type dog in the shadows” of her disused tennis court. That was enough for my father to interrupt my homework.
We set off in his blue and black Jensen car which he had brought back from England. It was hardly the right vehicle for the rough roads we travelled that day. Five and a half hours later, we found the run-down old property. Sadly, she told my father that the “dingo dog” hadn’t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle for Spider.

7 . While it throws out about 90 pounds of food per person every year, Japan doesn’t rank at the top of the world’s list of wasteful nations. Still, what’s thrown away represents a serious problem for an island nation with limited landfill space and a goal of greater sustainability. Reinvention can offer an alternative. A Japanese company is taking vegetable peels, cooking oil and other used foodstuffs and making entirely different products.
Concrete is the most widely used construction material in the world, and its key element, cement, is a major polluter of greenhouse emissions. So what if a more sustainable alterative were possible by making cement with food waste, which also would help reduce greenhouse emissions from landfills where that waste would otherwise be thrown away? That’s the idea behind Fabula, a Tokyo-based start-up.
Researchers at Fabula created a recipe to make food concrete by drying leftovers and pressing them into a mold (模具) at a high temperature. The company, founded by researchers at the University of Tokyo, began with items commonly thrown away like cabbage and orange peels but found that almost any food item can be used. It now takes mostly coffee grounds and tea leaves to make its cement. The product’s durability depends on the components.
Fabula is currently producing made-to-order household items, such as coasters and dishes, while awaiting its patent. The goal is to make furniture and larger structures once the technology is able to make the cement more durable. Food production companies that can’t avoid generating waste during their processes have reached out to work with the company. “We hope to become a matching service between companies that have food waste and companies who want to build things out of such materials,” said Takuma Oishi, Fabula’s chief commercial officer.
Since the cement is 100 percent eatable, it could create opportunities during disaster response when temporary structures need to be built quickly. The people inside might even turn to them for food. If the technology advances enough, Oishi suggested, someday we may be able “to eat the homes or furniture when necessary”.

8 . If you live on this planet, there’s a decent chance you’ve seen the classic Star TrekEpisode, in which captain Kirk and several members find themselves in what appears to be another universe.
These days, it seems the idea of the multiverse—many worlds—is having its Hollywood moment. Its appeal as a storytelling device is obvious—characters explore a multi-world with varying degrees of similarity to our own, as well as different versions of themselves. Hence, it has been fully established in mainstream pop culture.
While Hollywood can’t seem to get enough of the multiverse, it remains deeply controversial (有争议的) among scientists. Advocates on the two sides show no mercy toward each other in their books, on their blogs. But physicists didn’t pull the idea out of thin air—rather, several distinct lines of reasoning seem to point to the multiverse’s existence. However, critics warn that making the multiverse legal could make it harder for the public to distinguish speculative (推测性的) theories from established fact, making it more difficult to keep pseudo-science (伪科学) at bay. Giving credit to such speculation risks “turning fundamental physics into pseudo-science”.
The multiverse controversy is rooted in the idea of test ability. If we can’t interact with these other universes, or detect them in any way, some experts insist that reduces them to mere philosophical speculation. But Carroll, an advocate for “many worlds”, argues that mathematics is the language describing our physical theories. Since Schrdinger’s equation (方程), on which Quanturr (量子) mechanic rests, predicts the existence of many worlds, so be it.
Could a more expansive view of the universe itself be the next breakthrough? As Siegfried puts it: “Every time in the past that we’ve thought, ‘We’ve got it; this is what the whole universe is’—the people who’ve said, ‘Maybe there’s more than one of those’ have always turned out to be right.”
1. Why is Hollywood so occupied with the multiverse?| A．It makes for engaging plots. |

| A．it can be detected somehow |
| B．it can be reasoned logically |
| C．it can be interpreted philosophically |

| A．Doubtful. | B．Dismissive. | C．Unclear. | D．Approving. |
9 . Cancer-fighting genes in elephants could help tackle one of the biggest killers of people, according to research. Despite their large bodies and long lifespans, elephants are much less likely to die from cancer than humans, with death rates of less than 5 percent.
The paradox has puzzled scientists because more cells lead to greater replications (复制), which increases the possibility of the body failing to detect damaged DNA or a faulty cell that can result in tumors(肿瘤). Elephants live for almost as long as humans and weigh up to five tons.
However, a group of British and European scientists say they have taken a big step towards solving Peto’s paradox, named after the British epidemiologist Sir Richard Peto. Elephants, they say, carry a much larger more diverse group of tumor-fighting proteins.
The findings, published last week in the journal Molecular Biology and Evolution, raise hopes that the cancer fighting genes in elephants could be the key to tackling cancer, which kills about 167, 000 Britons yearly. Cells keep dividing throughout an organism’s life, each carrying the risk of producing a tumor. One of the body’s weapons is a gene called p53 known as the “guardian of the genome”, which hunts cells with faulty DNA. It encourages the cell to repair itself or self-destruct, keeping the cell from combining with others and producing tumors.
Humans have two versions of p53 but elephants have 40, said the researchers. Biochemical analysis and computer simulations also showed that an elephant’s p53 genes are structurally slightly different, providing a much larger anti-cancer toolkit. The researchers suspect that while faulty cells might be able to skirt two p53 versions, they cannot combine with other cells as easily in the face of dozens.
The findings will open the way for research on how p53 genes of elephants are activated and on medical treatment for humans.

10 . For the first time, United Nations members have agreed on a unified treaty (协议) to protect biodiversity on the high seas, representing a turning point for vast stretches of the planet where conservation has previously been held back by a confusing patchwork (拼凑)of laws.
The UN Convention on the Law of the Sea came into force in 1994, before marine biodiversity was a well-established concept. An updated framework to protect marine life in the regions outside national boundary waters, known as the high seas, had been in discussions for more than 20 years, but previous efforts to reach an agreement had repeatedly failed. The unified treaty, which applies to nearly half the planet’s surface, was reached late on Saturday.
UN Secretary-General Antonio Guterres welcomes the finalization of the text of the United Nations Ocean Treaty, his spokesman said on Saturday. “This breakthrough, which covers nearly two-thirds of the ocean, marks the culmination of nearly two decades of work and builds on the legacy (遗产)of the United Nations Convention on the Law of the Sea,” a statement said.
Nichola Clark, an ocean expert at the Pew Charitable Trusts called the long-awaited treaty text “a once-in-a-generation opportunity to protect the oceans-a major win for biodiversity”. The treaty will create a new body to manage the conservation of ocean life and establish marine-protected are-as on the high seas. Clark said that’s critical to achieving the UN Biodiversity Conference’s recent promise to protect 30 percent of the planet’s waters, for conservation. The treaty also establishes ground rules for conducting environmental impact assessments for commercial activities in the oceans.
Treaty negotiations were initially anticipated to conclude on Friday, but stretched through the night into Saturday. The making of the treaty represents “a historic and overwhelming success for international marine protection,” said Steffi Lemke, Germany’s environment minister.
1. What can we learn about the UN Convention on the Law of the Sea?| A．It is the basis of the UN Ocean Treaty. | B．It leads to a lot of controversy. |
| C．It has been discussed for over 20 years. | D．It is a complete failure. |
| A．Beginning. | B．Impact. | C．End. | D．Break. |
| A．Commercial ocean activities will be monitored. |
