1 . If anyone had told me three years ago that I would be spending most of my weekends camping, I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me.
The friends who introduced me to camping thought that it meant to be a pioneer.
I was, nevertheless, talked into going on another fun-filled holiday in the wilderness.
| A．This time there was no tent. |
| B．Things are going to be improved. |
| C．The trip they took me on was a rough one. |
| D．I was to learn a lot about camping since then, however. |
| E．I must say that I have certainly come to enjoy camping. |
| F．After the trip, my family became quite interested in camping. |
| G．There was no shade as the trees were no more than 3 feet tall. |
2 . The number of weather-related disasters has increased by five times over the past 50 years, the latest report by the World Meteorological (气象) Organization (WMO) said on September. However, thanks to improved early warning systems and disaster management, the number of death from these hazards (危险) has been almost three times less.
According to the WMO, from 1970 to 2019, weather, climate and water hazards accounted for 50 percent of all disasters. Among the top 10 hazards that led to the largest loss of human life during this period were droughts, storms, floods and extreme temperatures. However, deaths fell from over 50, 000 in the 1970s to less than 20, 000 in the 2010s.
“Weather, climate and water extremes are increasing and will become more frequent and severe in many parts of the world as a result of climate change,” says WMO Secretary-General Petteri Taalas.
“That means more heat waves, drought and forest fires such as those we have observed recently in Europe and North America. We have more water vapor in the atmosphere, which is worsening extreme rainfall and deadly flooding. The warming of the oceans has affected the frequency and area of existence of the most intense tropical storms.”
“Economic losses are increasing as exposure increases. But behind the statistics lies a message of hope. Improved multi-hazard early warning systems have led to a significant reduction in deaths. Quite simply, we are better than ever before at saving lives,” Taalas said.

4 . People use laughter to connect and bond with others. It’s how we tell friends that we find their jokes funny, or how kids in a park show that they are having fun. Laughter is so important to humans, even if they belong to different cultures or speak different languages. What about animals? Scientists are studying if there is a connection between animals’ laughing and playing.
Sasha Winkler, from the University of California, Los Angeles (UCLA), studies biological anthropology (人类学)，including the study of animal behavior. She noticed that the small monkeys she worked with, liked to play together by chasing each other. While having fun together, they made panting (喘气) sounds, almost like they were out of breath, which reminded Winkler of their quiet laughter. This made Winkler wonder whether other animals did so while they were playing.
To find out whether other animals laugh and play, Winkler teamed up with another scientist named Greg Bryant, a professor and vice chair in the Department of Communication at UCLA. Together, they found and read dozens of reports written by other scientists who study animals. Winkler and Bryant looked for any mentions in any animal of sound signaling like the panting of the monkeys during their playing.
In April 2021, Winkler and Bryant published their findings in a science journal. Through their research, they identified 65 species or groups of animals, which laugh while playing. The animals that laugh the most include primates (灵长类) like monkeys and apes, rodents (啮齿动物) like rats, and mammals that live in the ocean like dolphins. Their work won’t only help us understand animals better but it could also help us understand how humans develop or change over time. Next, they will carry on more study to find more.

5 . Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein’s jobs is defending an industry behind the plastic shopping bags.
Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.
Among the bag makers’ argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.
The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.
Environmentalists don’t dispute(质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

6 . I’ve been in an 18-year love-hate relationship with a black walnut tree.
It’s a unique tree. In late September or early October, falling fruits as hard as baseballs threaten the skulls (头骨) of you, your children, your neighbors and those that reside next door to them. Umbrellas in the yard are a must while dining in early August, and as for me, I wear my bike helmet while working in the garden.
The black walnut also releases a chemical substance through its roots as a competitive strategy. It’s poisonous to several common plants. There have been many new plant varieties that I brought home with hopes that maybe the black walnut would accept them, but they failed to flourish.
What does work are native plants that naturally grow in the area. Native plants are important to have around since they provide beneficial pollinators (传粉者) like birds, bees and butterflies with seeds and contribute to a healthy and biodiverse environment. Native plants for this area are generally easy to grow, so they experience less stress.
Have I thought of getting rid of this giant pain in my tiny backyard? Yes, however, getting rid of this tree standing at 50 feet with an 87-inch trunk is next to impossible. It’s also protected under the law. Rightfully so. Trees are important to the urban forest and for all of those that inhabit it.
Sometimes I think about my life without the black walnut. I can’t imagine a spring without the birds who arrive every year and loudly sing their songs before dawn. I’d miss falling asleep on lazy weekend afternoons as I look up into its leaves.
Every spring, I wonder what the season holds: What are the chances of being knocked unconscious while barbecuing? Like any good relationship, I’ll never be pleased. I’m stuck with this tree, so I’ll listen to its needs and give it the space it requires. In return, my walnut offers a habitat for wildlife and a reminder.

7 . Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.
Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.
Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair（婴儿车）, she frequently records pollution levels which are much higher than the data gathered by the Environment A gency.
The doggy data research was the idea of Baggy's 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma（哮喘）.
Matt Hunt said he was "very proud" of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma."
“Tom built up a passion for environmental protection at a very early age," Matt added. “He became very interested in gadgets（小装置）. About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don't we put it on Baggy's collar and let her monitor the pollution？'So we did it."
Tom said, "Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her."

8 . Should We Create More National Parks to Save Endangered Animals?
Don’t you find it worrying that more and more species of animals are in real danger of becoming extinct?
On the other hand, some people fight against the creation of national parks because they consider it is wrong to interfere with nature. They believe that wild animals are happier living in their natural environment.
All in all, these disadvantages are far less important than the benefits of national parks.
| A．To begin with, animals are important to humans. |
| B．Some hunters even hunt animals simply for sport. |
| C．I personally believe that we must save these animals. |
| D．These parks allow animals to live in a safe environment. |
| E．Firstly, national parks protect these animals’ natural environment. |
| F．They say though the animals may face danger, they enjoy a free life. |
| G．There is a heated discussion about whether to create more national parks. |
9 . A new study on 26 chimpanzees (黑猩猩) from zoos around the world found that chimpanzees can recognise family members and long lost friends even after decades of separation.
The participating chimpanzees were given juice while staring at a screen flashing side by side photos of other chimps. One animal from each pair of photos had lived with the group for at least a year, while the other was a stranger. An eye-tracking camera recorded where the participants were looking and for how long. Data showed their eyes rested longer on familiar groupmates, suggesting “rich recognition of each other.”
There is also evidence that they became more intent when shown a picture of a chimpanzee with whom they’d had more positive interactions, compared with conflicting relationships.
In the most impressive case, a 46-year-old chimpanzee named Louise repeatedly demonstrated “intense” attention upon seeing photographs of her sister Loretta and nephew Erin, whom she hadn’t seen in more than 26 years. The team said Louise’s results represent the longest-lasting social memory documented in any non-human animal to date.
“We tend to see ourselves as unique special creatures with incredible intellectual (智力的) capacities that are very different from other animals on earth,” said Laura Simone Lewis, a postdoctoral fellow in Berkeley’s psychology department and lead author of the study. “This study is showing us how similar we are to chimpanzees.” She noted that the findings support the theory that long-term social memory in humans and modern day chimps has come from “our last common ancestor that lived somewhere between 5 to 7 million years ago” who also likely had long-term social memory.
Now that they have definitive evidence that these endangered species possess long-term social memories, researchers have more questions, including whether chimpanzees miss the individuals they’re no longer with, especially their friends and family. “Our study doesn’t determine they are doing this, but it raises questions about the possibility that they may have the ability to do so,” Lewis said.

10 . 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.
