On a hot September afternoon, Peter and his friend Isabel were on their way to the library. When they passed by Tubman park, Isabel suggested cutting through it to get to the library. As they entered the park, the sight of the swings (秋千) and the merry-go-round brought back a flood of memories of their childhood spent there. But now everything looked so old, sad, and dirty. Litter lay on the ground next to an overflowing trash bin. There were still young schoolchildren playing there but they had to avoid the trash that littered the playground. A little boy told them that the city took the other trash cans away and the remaining one never got emptied often.
As they headed toward the library, the two high school students wrinkled their forehead. In the library, they encountered Mrs. Evans, their kind-hearted fifth-grade teacher, retired yet still passionate. Mrs. Evans listened as Isabel and Peter eagerly explained what they’d seen. Finally, she recommended them to go to the City Hall to voice their concerns.
The next day, Isabel and Peter went into the building of the City Hall but were met with an impatient officer. They were informed that the city couldn’t help with their problem due to a tight budget. Discouraged, they left and turned to Mrs. Evans for help.
Under her guidance, they decided to ask Go Green, a non-profit organization whose goal is to protect the environment, for help. “This group is good at raising money for projects just like yours, ” said Mrs. Evans. She promised to arrange them to present their ideas to Go Green. Hearing this, their face lit up.
Two main tasks remained ahead: researching ways to clean up the park and preparing a convincing presentation. As Isabel was good at researching while Peter always had a talent for speaking, they cooperated quite well. Isabel learned from a science magazine that a new type of trash bin can squeeze the trash down without being emptied often, which saves time, money, and energy. Based on this, Peter practiced his presentation over and over again.

4 . The rechargeable lithium-ion (锂离子) battery market is worth more than $50 billion. Lithium-ion batteries, whose demand continues to go up day by day, are used in a wide range of electronic devices. They are made of four main components, and cathode (阴极) is one of them. The cathode’s active material type is what determines the capacity of a battery.
A recent study, led by Wang Yan, a material scientist of Worcester Polytechnic Institute, finds that lithium-ion batteries made with recycled cathodes work better than those with new cathodes.
“The battery industry is expected to grow sharply in the next decade. This high demand has led companies to go to extremes, like increasing deep-sea mining, to gain access to the minerals used in lithium-ion batteries,” Wang said. “Mining minerals will have environmental impacts. Recycling spent lithium-ion batteries offers a way out.”
But until now, the prospect of using recycled materials in lithium-ion batteries has some manufacturers (制造商) worrying that it could impact performance. Thus, lithium-ion batteries are still not widely recycled. Aware of decreasing resources and environmental impact, Wang and other researchers set out to find a way to make recycling lithium-ion batteries economically practical. Through experiments, they could recover more than 90% of the key metals from spent batteries. These recovered metals became the basis of the new recycled battery’s cathode’s active material.
In tests between Wang’s team’s recycled batteries and brand-new batteries of the same composition, the recycled batteries outperform the new ones in their ability to maintain capacity. It took 11,600 charge cycles for recycled cathode batteries to lose 30 percent of their original capacity. That was about 50 percent better than the 7,600 observed cycles for new cathode batteries, the team reported. Those thousands of extra cycles could translate into years of better battery performance, even after repeated use and recharging.

5 . A carbon capturing device, called Orca, began operating in Iceland in September. The machine was invented and made by a Swiss company called Climeworks. The name comes from the Icelandic word orka which means energy.
Orca can pull carbon dioxide out of the air and send it deep into the ground, where it is turned into stone. The device is made up of four sections which look like giant air conditioners stacked together. Each section contains 12 large fans that suck air from outside into steel compartments.
Inside, the air passes through a filter (过滤器) which gathers the carbon dioxide. It is then heated to a high temperature so the carbon dioxide can be collected from the filter. Then, the carbon dioxide is mixed with water and put deep in the ground into a type of rock called basalt. Basalt causes the carbon dioxide mixture to turn into stone after two or three years.
Orca is an experimental device. It was built to demonstrate that it is possible to permanently remove carbon dioxide from the atmosphere. It can remove 4, 000 metric tons of carbon dioxide from the air each year. That’s about the same amount as the emissions produced by 850 cars in a year. In order to remove enough carbon dioxide to make a big difference to global warming, much larger devices like Orca would have to be built in many countries around the world.
Some environmental activists say governments should spend more time and money on reducing the amount of greenhouse gas we produce each year, instead of investing in carbon capture methods. But others say that, in order for countries to meet their goal of net zero emissions by 2050, they will need to do both: reduce new emissions and remove the carbon dioxide already in the air.

6 . 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 been 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. |
A.Take immediate actions. |
B.Put off the conference. |
C.Have online talks. |
D.Improve global economy. |
A.Abandoned. | B.Destroyed. | C.Rearranged. | D.Disturbed. |
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. |

9 . Plastic fishing nets, the so-called ghost nets, abandoned yearly in the sea—about 1 million tons—are more than just rubbish; they’re a killer. Fish, sea birds, and turtles get caught in the netting and die, with more species at risk.
Much shocked at this, Pranveer Singh Rathore, a materials-science engineer and materials R&D manager at Samsung, and his team set themselves the task of giving new life to the deadly nets. Last month, Samsung revealed a new line of Galaxy products made in part from recycled plastic fishing nets for the first time. The company estimates this year alone it can recycle over 50 tons of ocean-bound plastic into the key components that will go into its smartphones, tablets, and computers, thus taking a bite out of the global ghost nets problem.
It’s no small task to give waste fishing nets a second act. The nets are typically made of a substance called nylon which tends to dramatically degrade (降解) the longer it sits in the ocean and is exposed to the sun. “This makes it nearly impossible to use abandoned fishing nets directly,” Rathore explains. Besides, high-performance smartphone, tablet, or PC has to be waterproof and can survive severe weather. The nylon in the fishing nets falls far short of that level of durability (耐用).
To deal with that problem, Samsung last summer teamed up with two partners: one to collect and transform the nets into tiny nylon pellets (颗粒) while the other to strengthen their toughness and durability. The end result: The partners hit upon an eco-friendly and high-performance plastic material that’s being used to build the component parts for its latest line of products. For example, two parts of the Galaxy S22 mobile phone—the key bracket and the inner cover—are made of these fishing-net plastic materials. Samsung aims to use even more upcycled materials in future product lines.
“That’s the hope for the globe and our mission,” Rathore smiles.
