1 . Have you ever had the feeling that you can’t think when there is too much noise around? Did you ever think a fish could experience that feeling too? A recent paper published in Science titled “Soundscape (声景) of the Anthropocene Oceans”, combined over 10,000 scientific papers, confirming that undersea life knows that exact same feeling, more often than not. Anthropogenic (人为的) ocean noise, also known as underwater noise pollution, has created a dramatic impact on marine life due to “human-caused” activity within and neighboring our oceans.
Disney Pixar’s animated film Finding Nemo educated us about the ocean, and specifically within the ordinary world of a clown fish. A fact many may not know is that clown fish spend the first part of their lives as larvae (幼体), drifting with the current of the ocean until they become strong enough to swim against it. Once they are powerful and strong, they head home in sheltered coral reefs. There is only one drawback-the fish can’t physically see the reef, but they can hear it. The only problem is, if they can’t hear it, will they ever make it home?
Our anthropogenic ocean noise, such as cargo ships, ship and boat propellers (螺旋桨), surfing, deep sea mining, etc. are causing destruction of marine life. According to Time, sound is the sensory signal that travels the farthest through the ocean. Anthropogenic noise drowns out the natural soundscapes, putting marine life under immense stress. Altogether, this stress then affects their general health, disrupts their behavior, physiology, reproduction and, in extreme cases, causes death. Marine life can adapt to noise pollution, however, only if they can escape it. This only renders further complications of forcing species to leave their traditional breeding regions or their families.
Now, what if we told you there is already a solution? Multiple solutions, ideas and designs are currently in the works or already exist to reduce and reverse the damage of anthropogenic ocean noise. As Time explains, from wind-powered ships to noise-reducing propellers, floating wind turbines and “bubble curtains” that muffle construction noise, the solutions are already available and in some cases, cost-effective. The authors of the paper hope it will catch the attention of policymakers, who historically speaking, have ignored the matter still to this day.
Of all the challenges ocean creatures are battling, luckily sound pollution is the easiest compromise (妥协方案) humans can make. Once the noise has decreased, marine life will be able to better manage everything else it is up against.

3 . Rivers are very important. Humans rely on them for food and water. But rivers can destroy things, too. They can flood, or rise over their banks, making the water run into the nearby land. Floods can also kill humans and wildlife. However, floods are not always bad. Some ecosystems need them every once in a while.
Flooding can not only drown animals but also destroy habitats. For example, a flood in India in 2012 killed many one-horned rhinos. Flood waters can pick up dirt from riverbanks, which makes the water dirty. Too much dirt will clog rivers and streams, preventing the river from flowing. Sometimes flood waters can carry pollution to the sea and harm marine (海洋的) life. In addition, flood waters can carry disease, including hepatitis A and cholera.
However, not everything about floods is bad. Sometimes they bring new life to ecosystems. Flood waters carry nutrients (营养物) to the nearby land. Over time, the water dries up and leaves behind particles (微粒) of dirt and mud. The particles are called sediment (沉淀物) which can be good due to its ability to improve the dirt and helps plants grow. Floods are important to some animals as well. For instance, some animals see floods as a sign that it is time to mate or migrate. Floods leave sediment on river beds where baby fish can grow and carry nutrients for small animals in the water to eat. Moreover, in dry seasons, water might dry up, but floods help refill the wetlands, keeping the ecosystem going.
Floods are a part of nature. They can destroy living things and the environment. But some ecosystems need floods to survive.

4 . Zhu Dejun’s first job after graduating from college was as a road design engineer in his hometown, Alshaa League, North Chin’s Inner Mongolia autonomous region(内蒙古自治区). In 2011, when Zhu was conducting a road survey along with his colleagues, he saw a plant that he didn’t recognize. Later, Zhu learned that the plant was a saxaul (灌木梭梭) tree which is an excellent tree species for sand fixation and afforestation (造林) in desert areas. Known as a desert guardian, a fully grown saxaul tree can hold together a 10-square-meter patch of desert land, according to Zhu.
Zhu quit (辞去) his job at the design institute in 2014 and joined a nonprofit organization, the Society of Entrepreneurs and Ecology Conservation, or SEE, in the same year, concentrating on dealing with desertification (沙漠化) .During the past eight years, Zhu has been leading a team from SEE to plant saxaul trees in sandy areas in Alshaa League and other places of Inner Mongolia.
In 2014, the SEE launched a project titled “one million saxaul trees”, aiming to reach that number from 2014 to 2023, turning the desert of more than 133, 330 hectares (公顷) back into a satisfying ecosystem. By the end of 2018, half of the organization’s goal had been achieved. In 2016, Ant Finance cooperated with SEE to introduce the Ant Forest platform, not only encouraging people to choose “a low-carbon way” of shopping, traveling and living, but also to help control desertification.
Through the participation of a greater number of online users, who grow virtual trees, the SEE Foundation, set up in 2008, has been providing subsidies (补助金) for local herdsmen and farmers while also offering technological support to plant saxaul trees in desert areas. Now, Zhu is the head of the foundation’s project to fight desertification. He also gives lectures about saxaul trees and the fight against desertification at schools, hoping to raise awareness among young people.

6 . How crowded your neighborhood is can affect the health of our planet, a new study finds. Scientists measured the effect that people have on the environment using a carbon footprint. That footprint reflects the amount of carbon dioxide (二氧化碳)—a greenhouse gas—that is sent into the atmosphere because of people’s daily activities.
Carbon footprints tend to be low for citizens. Living in a suburb (郊区) outside a city, however, can be opposite.
People living in the city centers have low carbon footprints, the researchers found. “It is much easier to have a low carbon effect if your home is close to where you work, shop and play,” explains Jones. Living within walking or biking distance cuts back on the amount of carbon dioxide compared with moving people by cars. And cities with bus and subway networks allow people to travel great distances while keeping the amount of greenhouse gases low.
Not everyone can afford to live in the city, however. Suburbs offer more space, allowing people to build larger homes. Suburbs may offer better schools to kids. But those homes are usually far away from where owners work, play or learn. So people who live in suburbs often drive long distances.
The average household in a large city sends out about 40 tons of carbon dioxide per year. The average suburban household, however, sends out close to 50 tons of carbon dioxide per year.
The new findings are an important contribution to climate research. They would give scientists a better understanding of how culture might mix with locations to influence our carbon footprints.
You may not have any control over the location of your home. Still, everyone can take steps to reduce their carbon footprints. That’s because how much we pollute is influenced not just by where we live, but also by how we live.
To reduce your footprints, start small. Turn off lights when they’re not in use. Recycle or reuse things instead of throwing them away. And as people get used to making small changes, the leap to bigger ones will get easier.
1. Why do people living in suburbs have higher carbon footprints?| A．Because they often drive to work, play or do other things. |
| B．Because their homes take up too much space. |
| C．Because they often use buses and subways to travel great distances. |
| D．Because they have to send their kids to schools by car. |
| A．By giving examples. | B．By making comparisons. |
| C．By following time order. | D．By explaining processes. |
| A．People living in big cities produce more carbon dioxide. |
| B．Culture plays the most important role in influencing the environment. |
| C．Any process of making new products may pollute the environment. |
| D．One’s small step can make a big difference to the environment. |
| A．Health. | B．Sports. | C．Culture. | D．Environment. |
7 . If you’d like to go sightseeing, the following World Heritage sites (世界遗产保护地) may be your best choices.
Jiuzhaigou Valley Scenic and Historic Interest Area
Jiuzhaigou Valley, which lies in the northern part of Sichuan Province, China, reaches a height of more than 4,800m, with a series of different forest ecosystems (生态系统). It’s particularly famous for its narrow landforms and excellent waterfalls. Some 140 kinds of birds also live in the valley, as well as a number of endangered plants and animals, including the giant panda. Jiuzhaigou Valley was recognized as a World Heritage site by UNESCO in 1992.
Khami Ruins National Monument
The city of Khami, which developed after the capital of Great Zimbabwe had been given up in the mid-16th century, is of great archaeological (考古的) interest. The discovery of objects from Europe and China shows that Khami was a major centre for trade over a long period of time. It joined the World Heritage List in 1986.
Henderson Island
Henderson Island, which lies in the eastern South Pacific, is one of the few atolls (环礁) in the world whose ecology (生态) has been untouched by humans. It is particularly famous for the 10 plants and 4 birds that can only be seen on the island. It was recorded in the World Heritage List in 1988.

9 . While Ellard Hunting and fellow researchers were out studying the weather at a field station in England, they noticed something unexpected on their instruments. Though there was no storm coming, the scientists’ electric field monitors recorded a strange increase in atmospheric electric charge(电荷) .
Nearby, honeybees that lived in on-site hives were swarming (蜂拥) as they tried to find a new home. When the team took a closer look at their data, they discovered that the swarming honeybees had created an atmospheric electric charge. The researchers shared more details about their findings in the journal Science.
“This is the first report of biology as a source of space charge.” says Hunting, a biophysicist at the University of Bristol in England. Scientists had known that individual bees carry a small charge while flying through the air, caused by the friction of their body parts against the air and each other. It’s similar to how rubbing a balloon on a piece of cloth creates static electricity (静电). Scientists believe a bee’s charge helps pollen (花粉) stick to it and signals to other bees which flowers have already been visited. But until now, researchers had never recorded such a high voltage (电压) among swarming honeybees.
In terms of electricity generation, a bees warm’s charge isn’t so impressive：It would take about 50 billion bees to power an LED light. But compared to the charges produced by common weather events, the bees’ charge density was six times greater than an electrified dust storm and eight times greater than a thunderstorm cloud.
Scientists hope to continue exploring how biology influences physics and are curious to know if something similar is happening with other wildlife, such as birds and bats.
