Secondly, whaling activity is another killer. Historically, whaling has been popular in some overseas countries, such as England, Japan and Norway.
The fact that whales have become endangered animals is alarming us. Some
2 . Levi Draheim, 11 years old, and 20 other young people have accused(控告)the us encouraging the climate change. For more than a century, human activities have been increasing the amount of greenhouse gases in the atmosphere. That has caused a host of effects globally, from changes in weather to ice melting at the poles.
Levi lives in Satellite Beach,Fla. He once had to leave his home because of strong storms. He rains flooded the town’s streets. And he had trouble breathing during red tides, which can develop wt harmful ocean algae(海藻)grow out of control.
Climate change is making these events more frequent. Levi and his family also have another climate-change-related problem. Sea level is rising. “If climate change worsens, the island that I live or will be gone,” he explained.
The young people say the US government allowed the use of fossil fuels(矿物燃料). Burning those fuels gives off greenhouse gases, driving climate change. The youths want the government to solve the problem of pollution. So they took the government to court in 2015.
The case has had several hold-ups. In the beginning, the government asked the trial court(初审法庭) to refuse to accept the case. The court didn’t do that. Then they turned to the Ninth Circuit Court of Appeals. That court said the case could go ahead, and the Supreme Court agreed. Both sides did work to get ready for trial. But the government again tried to get the case thrown out without a trial.
Finally, trial was set to start on October 29, 2018. But on October 19; the US Supreme Court Chief Justice John Roberts told the trial court to hold up. The youths’ lawyers objected. On November 2, the Supreme Court finally agreed that the trial could go forward. Right now, it is hard to say when that what happen.

4 . On September 29, 2021, the US Fish and Wildlife Service declared it would be removing 23 species from its Endangered Species Act, including the ivory-billed woodpecker, various Hawaiian birds and freshwater fish, not because they had pulled back from the edge of extinction, but because the USFWS believed these species would never recover, and were most likely extinct, therefore not requiring protection.
In April, 195 countries are getting together in China for a UN conference to discuss global agreements to protect nature and biodiversity, with the hope of finalizing an agreement to safeguard plants, animals, and ecosystems. However, the new strain(毒株)of Covid-19, Omicron, has potentially thrown the plans into a mess, and negotiators may switch to online talks if travel restrictions to China are put in place again.
“We can’t go another four months without any progress” said Georgina Chandler, senior international policy officer at the Royal Society for the Protection of Birds. Conservationists are urging the talks to go ahead—online if necessary—as the biodiversity crisis shows no sign of slowing up.
“Nature loss has not gone away and threatens both human lives and the global economy,” said Lin Li, director of global policy at the organization. “With one million species currently in danger of extinction, delaying action is not an option.”
Improving conservation and management of natural areas, such as oceans, forests, and wildernesses is crucial to safeguarding the ecosystems on which humans depend. However, forests are still being devastated, often for farming or commercial use. As trees absorb about a third of planet-warming emissions produced worldwide, stopping deforestation is key. At COP26 in Glasgow last November, world leaders plan to invest $19 billion in public and private funds to protect and restore global forests.
It’s easy to feel disheartened by the disappointing news, but the only way to stop more species suffering the same fate is to pay attention and take actions.
1. Why would the 23 species be removed from the Act?| A．Because they are less endangered. | B．Because they have already died out. |
| C．Because more fund is in need to protect them. | D．Because nothing can save them from extinction. |

| C．Have online talks. | D．Improve global economy. |
| A．To explain why some species have disappeared. |
| B．To recommend ways to protect and restore forests. |
| C．To describe the present situation of global ecosystem. |
| D．To call for attention and action against biodiversity crisis. |
5 . For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside.
Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. When builders began making houses and offices, they did not want to waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also used man — made building materials which are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building green plants.
Scientists believe that a plant’s leaves absorb the pollutants (污染物). In exchange the plant lets out oxygen through its leaves. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants.

6 . Soot (煤) pollution is speeding up climate-driven melting in Antarctica, a new study suggests, raising questions about how to protect the delicate continent from the increasing number of humans who want to visit.
“It really makes us question, is our presence really needed?” says Alia Khan, one of the authors of the new study. “We have quite a large black carbon footprint in Antarctica, which is enhancing snow and ice melt.”
Black carbon is the leftover thing from burning plants or fossil fuels. Soot in Antarctica comes primarily from waste gases of cruise ships (游轮), vehicles and airplanes, although some pollution travels on the wind from other parts of the globe. The dark particles (微粒) coat white snow and absorb heat from the sun the way a black T-shirt does on a warm day. The blanket of dark bits speeds up melting that was already happening more quickly because of global warming.
When snow and ice are uncovered, they reflect an enormous amount of sunlight before it can turn into heat. “These are the mirrors on our planet,” says Sonia Nagorski, a scientist at the University of Alaska Southeast. “When those mirrors are covered in a film of dark bits, they don’t send back that much light and heat. That means more heat is trapped on Earth, speeding up melting and contributing to global warming.”
As a scientist who personally visits Antarctica every year, Khan says she is troubled by her own research results. On the one hand, she goes to Antarctica to collect crucial data about how quickly the snow and ice there are disappearing. “But then when we come to conclusions like this it really does make us think twice about how frequently we need to visit the continent,” she says, “and what kind of regulations should be placed on tourism as well.” That could mean requiring that cruise ships and vehicles be electric, for example, or limiting the number of visitors each year.
1. What is Khan’s attitude towards human actions in Antarctica according to paragraph 2?| A．Angry and abusive. | B．Cold and uninterested. |
| C．Doubtful and anxious. | D．Admiring and delighted. |
| A．The quick melting of ice and snow. | B．The emission from virous transport. |
| C．The remaining parts of burning plants. | D．The floating gases from other continents. |
| A．The covered ice is less reflective. |
| B．The melting speed of ice is slower than before. |
| C．The dark blanket serves as a big mirror. |
| D．The sunlight gets increasingly stronger recently. |
| A．What made our planet so polluted? | B．Who is to blame for air pollution? |
| C．Can electric vehicles save tourism? | D．Are we welcome to the South Pole? |
7 . A team led by researchers from the UK examined waterbird data from 1506 protected areas and analyzed more than 27, 000 bird populations across the world. They compared waterbird populations before and after the establishment of protected areas and also compared trends of similar populations within and outside of protected areas.
“Our study shows that, while many protected areas are working well, many others are failing to have a positive effect, ” lead author Hannah Wauchope says in a statement. “In the majority of places we looked, bird populations were stable or were increasing, but some of them weren’t doing any better than in unprotected areas, “ she adds. “That’s disappointing, but not surprising. There seems to be the disconnection between people talking about how much land is protected and whether those areas are actually doing anything positive. ”
This study comes ahead of a United Nations meeting in China to discuss biodiversity goals for the next decade. Several countries have already committed to protecting 30 percent of the planet by 2030, yet the researchers say this alone does not necessarily guarantee positive out- comes for species.
“An obsession(迷恋)with reaching a certain area-based target-such as 30 percent by 2030-without focus on managing existing protected areas appropriately will achieve little, ” co-author Julia Jones says. “When world leaders gather in China later this year to set targets for the next decade, I really hope to see a change of their focus, rather than simply saying how much surface area they are going to protect. ”
According to Thomas Brooks, chief scientist at the International Union for Conservation of Nature, who was not involved in the study, waterbirds are a good example of a group facing the consequences of human behaviors that cause biodiversity loss. These animals respond quickly to changes in site quality and are broadly distributed, clearly reflecting the impact of protected areas.

8 . After taking a few steps back to get a running start, Hadj Benhalima dashed toward the building, pushed against its wall with his foot, pushed himself upward and stretched out his arm.
At the peak of his leap, he fingered oft a light switch, more than 1o feet off the ground. The bright lights of a nearby barbershop went off instantly
Groups of young athletes practicing Parkour—the practice of passing obstacles in a man—made or natural environment through the use of running, vaulting (腾跃), jumping, climbing, rolling, and other movements in order to travel from one point to another in the quickest and most efficient way possible without the use of equipment—have been swinging around big French cities switching off wasteful shop signs at night, in an effort to fight light pollution and save energy.
These so—called Light Off operations have become extra popular in recent months, with France embarking on energy conservation efforts.
Paris, the City of Light, is a favorite target. While its landmark monuments now go dark earlier than usual, many store signs still stay lit all night.
“Everyone can contribute in their own way” to save energy, said Kevin Ha, the leader of the Paris—based Op he Spot Parkour group, with about 20 members. “We put our physical abilities to good use.”
Enforcing the orders in place of the authorities certainly enters a legal gray area. But the group said all the police officers they have met during their rounds have approved of their deeds—as long as it causes no damage.
1. Which of the following options is NOT Parkour’s feature?| A．It doesn’t need any tools to assist movement. |
| B．It can only be practiced in an enclosed environment. |
| C．It aims to travel from one point to another in the quickest way. |
| D．It is practiced through running, vaulting, jumping, climbing, etc. |
| A．To invite more youths to join them in competition. |
| B．To overcome physical boundaries and build fitness. |
| C．To reduce the consequences of energy consumption. |
| D．To tour around feeling the unique beauty of Paris at night. |
| A．They are honest. | B．They are creative. | C．They are selfish. | D．They are optimistic. |

| D．They held an indifferent attitude towards them. |
9 . Chinese scientists say they have developed a robotic fish that can remove microplastic particles from water environments. Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world.
The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical Compound. The robots are designed to absorb microplastics while moving through the water. The project was launched by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow water and they plan to carry out more tests in deeper waters. The scientists reported their findings in a new study in Nano Letters. The publication comes from the American Chemical Society, a nonprofit organization supported by the U.S. Congress. The robotic fish were built to target microplastic particles, which are smaller than five millimeters. Studies have confirmed that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown of manufactured plastic products and industrial waste.
The team said the robots can be controlled by light. Turning “a near-infrared light laser” on and off causes the fish’s tail to move back and forth, the American Chemical Society said. The robotic fish can swim up to 2.76 body lengths per second. The researchers said this is faster than most similar soft robots. Wang Yuyan was a member of Sichuan University’s research team. She told Reuters news agency that the small, lightweight robot is currently being used to collect microplastics for research purposes. But Wang added that the team plans to expand that use so the robot fish can remove larger amounts of microplastic waste from deep ocean areas. The fish can take in different kinds of microplastics and even repair itself when damaged, the researchers said. And if a robot fish is accidentally eaten by a real fish, it could safely digest the material, the team added. Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or disease.

10 . China has seen significant achievements in improving the environment and green development over the past 70 years, especially in fighting against desertification (沙漠化).
Desertification was a serious problem in the 1990s. It caused deadly sandstorms, which arrived like big black walls reaching up into the sky. As President Xi Jinping has said, clear waters and lush (繁茂的) mountains are invaluable assets (资产). Efforts to create “green” areas have played a crucial role in the country’s fight against desertification.
A series of campaigns have been conducted by the central government to improve the environment. For example, in 1998, China launched the Natural Forest Protection Program. Thanks to the program, forest coverage in China increased greatly from 12 percent in the 1980s to nearly 23 percent last year.
Another example of the campaign is the Elion Resources Group, which has been recognized by the UN for the development of a desert eco-industry that has slowed desertification.
In Kubuqi, a desert in the Inner Mongolia autonomous region, Elion has greened 600,000 hectares of land and helped lift more than 102,000 people out of poverty through the development of solar energy and tourism, as well as planting herbs for traditional Chinese medicine.
In addition, the group’s techniques have also been used in many important ecological programs, including Yangtze River Ecological Park and Qilian Mountain National Park.
“We will develop new ways to improve our ability to control the sand with the help of modern technologies, such as drones (无人机), AI, big data and the internet of things,” said Ao Baoping, chief executive officer of Elion Green Land Technology.
