Ten-year-old Sami loved to visit his grandfather's house. The house was near the beautiful blue sea. At the seaside stood thick and tall palm trees with green coconuts hanging from them. When the coconuts fell down, Sami would break them open and drink the coconut water. Sami liked to play under the trees. It was always great fun to spend the holidays at Grandpa's place.
This winter vacation, Sami was surprised when he came to his grandfather's village. There were hardly any trees left. He saw houses built near the sea. People had cut down many palm trees and there was hardly any greenery left.
Grandpa's house was different. He never allowed his trees to be cut. He hugged each palm tree in his courtyard. He also named the two big trees near the front door--one was Petu, and the other Betu. He had planted them with his own hands and today they had become large, massive trees with thick trunks. They were tall and green and gave the sweetest, juiciest coconuts.
One night, Sami was awakened by a strange sound. He could not sleep. He tossed（辗转）and turned in bed.
Suddenly, the ground shook as if the earth was splitting. He sat up straight and then ran to Grandpa. He clung（附 着）to his grandpa tightly. Grandpa cried out, “It's an earthquake! It's an earthquake!" They ran outside the house. They thought that would be safe.
Suddenly, there was a loud sound; the earth was not splitting but the sea was roaring. People were shouting, screaming and crying, “The sea is rising! The sea is rising." The villagers started running away from the beach.
Sami watched dumbstruck（呆若木鸡）.
The waves were rising higher and higher. Sami thought, “How big the waves are!" He went into the house again and saw water coming in from all sides. He was scared.
Sami remembered his mother telling him long ago, “You must always get out of the house if the floods come too near." He ran outside the house with Grandpa. But the water came surging（汹涌） in.
Waves about twelve meters high came rushing in, drowning everything. Water was all around and everywhere.
Paragraph 1：
Grandpa held Sami's hand tightly but a huge wave separated them.

4 . Last year, the bushfires in Australia burned more than 12.35 million acres of land. At least 25 people were killed and 2000 homes destroyed. According to the BBC, that was 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 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(严重) of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled bums 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).

5 . Some scientists have traced the increase in earthquakes, especially in areas not known for the presence of fault lines or past seismic (地震的) activity, to human actions. The idea of humans causing earthquakes may seem strange at first. After all, you can run around your backyard and jump up and down as you want, and the ground isn’t going to start shaking. However, scientists have identified a variety of large scale human activities that can result in earthquakes.
Scientists have confirmed over 700 places where human activities have caused earthquakes over the last century. While many human-related earthquakes are mild and don’t cause much damage, some of them can be serious and dangerous. In fact, scientists believe human activity has caused earthquakes with magnitudes as high as 7.9 on the Richter scale.
Scientists believe most human-related earthquakes are the result of mining. As companies drill deeper and deeper below Earth’s surface to get natural resources, holes left behind can cause instability that leads to collapses that cause earthquakes. Another human activity leading to earthquakes is fracking (水力压裂) for oil and gas, including the high pressure waste water processing that usually goes with fracking. In this process, water, sand and chemicals are pressed underground under high pressure to break rocks to release natural resources.
Building large dams can also cause earthquakes. For example, about 80, 000 people died in China in 2008 as a result of a 7.9-magnitude earthquake caused by 320 million tons of water that had been collected in the Zipingpu Reservoir after a large dam was built over a known fault line.
These aren’t the only human activities that can result in earthquakes, though. Scientists point out that earthquakes can also be caused by other human activities, such as construction of skyscrapers and nuclear explosions.

| C．Humans are to blame for some earthquakes. | D．Earthquakes are no longer nature-made. |
6 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

7 . For the past 13 years, Martin Burrows has been working as a long-distance truck driver. Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.
Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD. Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.
By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”
Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.

8 . Bioluminescence (生物发光) is a natural phenomenon wherein a chemical reaction within an organism’s body produces light. It can be found in many places in nature — fireflies, some mushrooms — but mostly in the deep sea.
Recently, Rambouillet, a small historic French town, has teamed up with a company called Glowee to turn the city into a full-scale bioluminescence laboratory. The goal is to change the way in which cities use light. The company uses marine (海的) bacteria harvested from the coast of France. It makes some of the town’s public light up in the cool blue of bioluminescence.
These bioluminescent bacteria are stored in a seawater filled tube, giving the bacteria room to float around and light up. The light provided by the bacteria is part of their natural metabolism, so producing the light requires no energy other than that which is needed to feed the organisms. This makes it much more environmentally friendly and sustainable than electric light, which consumes a huge amount of non-renewable energy.
“On the way to lighting up the world with bioluminescence, you have to feed the bacteria and add water as they grow. That’s not so easy. The phenomenon will be very temperature-dependent and I doubt that it will work in the winter. Also, bioluminescence is not very bright compared to electrical lighting, though they have improved the light intensity,” Carl Johnson, a professor from Vanderbilt University said.
One potential solution to these issues — and one that Glowee is looking into — is to remove the biological aspect of the whole process. Theoretically, luciferase (荧光素酶) can be removed from the bacteria and used to create light instead of the bacteria itself. Because luciferase is non-living, it doesn’t need to be fed. Creating new means of sustainable lighting is a way of being environmentally friendly without plunging the earth back into darkness.
