1 . Nanako Hama gets a lot of mail, mostly from strangers who live in her home city of Tokyo. In light envelopes, they send locks of their hair, hoping to recycle it.
People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change.
But hair possesses useful qualities and it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks,
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil.
“Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier, “That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil.
Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氪), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes-for oil and soil, ” Hama says.

3 . It has been over 150 years since the Great Chicago Fire. The 1871 fire killed an estimated 300 people. It turned the heart of the city, wood-frame buildings quickly constructed on wooden sidewalks, into ruins, and left 100,000 people homeless. Like the Great Fire of London in 1666, the San Francisco Earthquake of 1906, and Hurricane Katrina in 2005, the Great Chicago Fire reminds us that big cities can still be frail.
But that same night, about 250 miles north of Chicago, more than 1,200 people died in and around Peshtigo. It was the deadliest wildfire in U.S. history. Survivors said the fire moved like a hurricane, jumping across Green Bay to light forests on the opposite shore.
Chicago’s fire came to be seen as a disaster that also led to the invention of steel skyscrapers, raised up on the city’s ashes. It has overshadowed the Peshtigo Fire. And for years, the two were seen as separate disasters. However, many of those houses and sidewalks that burned in Chicago had been built with trees grown around Peshtigo.
Chicago’s fire was long blamed - falsely - on an Irish-immigrant family’s cow kicking over a lantern. Some people thought the Peshtigo Fire started when pieces of a comet (彗星) landed in the forest, which has never been proven.
What we understand better today was that the Midwest was historically dry in the summer of 1871. When a low-pressure front with cooler temperatures rolled in, it produced winds, which can fan sparks (火星) into wildfires. The fires themselves generated more winds. Several parts of nearby Michigan also burned during the same few days ; at least 500 people were killed there.
At present, all of those fires on an autumn night in 1871 might help us see even more clearly how rising global temperatures and severe droughts, from Australia to Algeria to California, have made forests easier to burn, and people more likely to be harmed by the climate changes we’ ve helped create.

4 . Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn’t know for sure? That the evidence was inconclusive, the science uncertain? That the anti-smoking lobby(游说) was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.
There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth’s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel’s report: “Science never has all the answers. But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions.”
Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it’s OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the time 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent person would take out an insurance policy now.
Fortunately, the White House is starting to pay attention. But it’s obvious that a majority of the president’s advisers still don’t take global warming seriously. Instead of a plan of action, they continue to press for more research — a classic case of “paralysis by analysis”.
To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research. But research alone is inadequate. If the Administration won’t take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial supports for private industry, is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

6 . Within the beautiful scenery of Wisconsin’s Lake Chippewa lies a natural wonder that is a unique challenge for the local community. This hidden wonder is exactly a giant floating island. The island, made up of plants and trees, sometimes floats around the lake, causing a major inconvenience by blocking (阻塞) an important bridge. Later, the local people came up with a solution to this problem. Every year, local boat owners work together and push the island away from the bridge.
Lake Chippewa was born in 1923 when a vast bog (沼泽) was changed through flooding. Soon after that, many of the dark bogs started rising to the surface and became perfect growing places for plants, with seeds carried by wind and wild birds to this floating place. Over the years, these bogs have grown plants and trees and turned into full islands. As time goes by, plants take root, and the oldest islands even have trees that act as sails (船帆) when the wind blows, moving the entire floating island around the lake.
Although the years-old floating island does not relocate (重新迁移) so often, when it does, it causes trouble for the community by blocking the important bridge that serves as the only passage between the lake’s East and West sides. The only solution is to gather a group of boats, and not just one or two, but dozens of boats working together to push the island away. “It takes a community’s effort, and you must have the winds at your back to push them in,” said a resident. Moving the island also requires precision (精确), as just relocating it a short distance may result in its return within days.
Some people have suggested destroying the floating islands to get rid of the problem. However, the big bog in Lake Chippewa has been around for many years, and during that time a variety of animal and plant species have made it their home. Therefore, local government advises they be dealt with in a way that won’t do harm to wildlife, paying more attention to the fine-drawn balance between human convenience and environmental protection. The annual tradition of relocating Lake Chippewa’s floating island is evidence to the coexistence of man and nature, a heartwarming display of community unity, and a reminder of the importance of preserving the unique areas that enrich our world.

8 . 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.

9 . The climate change has become an issue that no one can escape from. If the world wants to limit climate change, water shortage and pollution, we all need to choose “flexitarian” diets, say scientists.
This means eating mainly plant-based food, which is one of three key steps towards a sustainable future for all in 2050, they say. Food waste will need to be halved and farming practices will also have to improve, according to the study. Without action, the impacts of the food system could increase by up to 90%. Fast on the heels of the landmark report of the Intergovernmental Panel on Climate Change(IPCC) comes this new study on how food production and consumption impact major threats to the planet.
The authors say that the food system has a number of significant environmental impacts including being a major driver of climate change, providing freshwater and reducing pollution through over use of nitrogen (氮) and phosphorus (磷).
The study says that thanks to the population and income growth expected between 2010 and2050, these impacts could grow between 50%~90%. This could push our world beyond its geographic boundaries. So when it comes to climate change, the authors looked at what they called a “flexitarian diet”.
“We can eat a range of healthy diets but what they all have in common, according to the latest scientific evidence, is that they are all relatively plant-based,’’ said lead author Dr. Marco Springmann from the University of Oxford.
“You can go from a diet that has small amounts of animal products; some might call it a Mediterranean-based diet; we call it a flexitarian diet. We tried to stay with the most conservative one of these which in our view is the flexitarian one, but even this has only one serving of red meat per week,” he added.
If the world moved to this type of diet, the study found that greenhouse gas emissions (排放) from agriculture would be reduced by more than half.
1. What benefit will the new diets bring to the world?| A．The animals will be saved. | B．People will need more water. |

| D．Eat plant-based meal mainly and animal products sometimes. |
| A．The climate will become warmer. | B．The food consumption will increase. |
| C．People will have less greenhouse gas. | D．People will produce more food waste. |
| A．Supportive. | B．Doubtful. | C．Opposed. | D．Indifferent. |
