1 . Every tropical (热带的) forest looks different, particularly in the eyes of an ecologist, and Peter Ellis has been lucky enough to visit a fair few. One in particular holds a special place in his heart: the rain forests of Gabon. He first visited as a Peace Corps volunteer. “It completely changed the way I think about conservation and our relationship with nature,” he says.

These days, Ellis is the global director of natural climate solutions science at the US-based conservation organization — The Nature Conservancy, where he’s presently investigating the role that logging (cutting down trees) can play in tropical forests. Logging for forest conservation may sound contradictory, and it often is. But logging in a tropical forest looks different to the practices we might expect to see. “We might imagine it as a wasteland of stumps (树桩) after a clear cut,” says Ellis. Instead, only a few trees are actually removed. A sustainably logged forest is the one that remains a breathing, rich, tropical rain forest full of trees and wildlife, thus helping keep a large part of the biodiversity while ensuring that more damaging industries don’t take its place. It can also provide a means of basic livelihood for the local people.

The two years that Ellis spent in the Gabon rain forests opened his eyes to a different method of land management. “The locals took me out into the forest and taught me the names, usages and spiritual significance of all the trees and other plants in the forest,” he says. “Science is about exact, designed experiments, but it’s also about asking the right questions. And the people who live in those places and protect the ecosystem are more likely to help us learn what the right questions to ask are.”

Tropical forests are essential to our planet’s future as they support high levels of biodiversity and act as crucial carbon sinks (碳储存器). “We need to honour, and protect them so that they can do their job to help save us all” says Ellis.

3 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

It all began when my younger brother, Chris, and I went over to Aunt Barbara and Uncle Howard’s for Thanksgiving. My aunt and uncle live on a farm at the opposite end of town, and Chris and I love going there. The farm is situated in a valley surrounded by rolling hills. The fields are lush and green, with crops growing as far as the eye could see. The sound of chickens clucking and cows mooing fills the air. For my brother and me, it is a wonderland where we have a lot of fun.

We got up early and did the morning chores before we left. As kids, we talked happily about the feast along the way. Roasted turkey, cornbread stuffing, sweet potato, and cranberries were awaiting us. We were curious to know how a turkey could grow so big. When we finally got to my aunt and uncle’s, Chris and I went outside to see if Uncle Howard needed help with anything. He and Dad had decided to clean out the turkey coop (笼子) before dinner. Since Chris was only nine, he got the easier job of scrubbing out the watering cans. I was twelve, old enough to help load the wheelbarrow (手推车). Work was tough, but we still found time to ask Uncle Howard a lot of questions about turkeys. He must have been impressed, because when we were finished, he winked at my dad and handed me a turkey egg. “You kids put it under a setting hen,” he said, “and in twenty-five days, you’ll have a fine turkey!” Chris was so excited that he nearly dropped his egg on the way to the house. We both stuffed ourselves at dinner and then couldn’t wait for the grownups to finish talking so we could go home and tend to our egg.

Dad put the egg under an old hen, and every day Chris and I would check to see if it’d hatched yet. Twenty-five days seemed like forever.

Para. 1. Finally, on the twenty-sixth day, Chris and I walked into the coop after school.

4 . Look, let’s be honest-there’s no such thing as a “green” vacation. You’ll leave a carbon footprint, no matter what.     1     Here are a few questions to ask:

Is it a B Corp?

B Corps are businesses that meet a strict set of standards by the nonprofit B Lab. They include requirements for governance, workers, customers, community and the environment.     2     You’ll see some fairly well-known brands, like Intrepid Travel. But you won’t find the names of any major airlines, car rental companies or hotel chains-at least, not yet.

Does the company have any other environmental certifications?

Third-party certifications from Green Key, LEED and WELL can be signs that a travel company means business about the environment. Transportation companies may also offer verified certifications from organizations like Terrapass or the Gold Standard Foundation.     3     However, it’s a good start.

    4    

If the company claims to be green, don’t just take its word for it. Listen to what it says. If you see nothing but models on its Instagram channel or ads for online discounts on its site, perhaps it’s a shade of fake green. “A company’s social media strategy is generally a reflection of its current ethos and goals,” explained Julia Carter, founder of Craft Travel.

How deep is its commitment to the environment?

    5     For example, the Travel Corporation publishes an annual impact report that maps its progress against 11 sustainability goals developed by the United Nations. Many cruise lines also publish detailed reports that allow you to check their commitment to the environment against several objective standards.

A．But your trip can be green-ish.

B．What’s the company saying to everyone?

C．How can we find a reliable company online?

D．Don’t trust anything the company says to the public.

E．These certifications aren’t a guarantee the company is green.

F．Look for reliable reports on sustainability from a travel company.

G．You can search the directory of these forward-looking companies online.

6 . A recent study conducted by the Massachusetts Institute of Technology (MIT) has discovered that river erosion (侵蚀) can lead to increased biodiversity in areas with minimal tectonic (地壳构造的) activity. The researchers focused their attention on the Tennessee River Basin and examined how the erosion of various rock types by the river had led to the separation and diversification of a type of fish called the greenfin darter. As time passed, these separate fish populations evolved into distinct families with genetic differences.

Scientist Thomas Near observed that the greenfin darter was exclusively found in the southern half of the Tennessee River Basin. The researchers analyzed the genes of each fish in Near’s data set and constructed an evolutionary tree. This tree helped them comprehend the evolution and differences of the greenfin darter species. They discovered that the fish within the same branch of the river were more closely related to each other than to the fish in other branches.

This study provides evidence that river erosion significantly impacts biodiversity in regions with low tectonic activity. It illustrates how changes in the landscape caused by river erosion can lead to the division and diversification of species over time, even in peaceful environments. These findings enhance our understanding of the mechanisms (机制) that drive biodiversity and evolution, even in areas that are not typically associated with intense tectonic activity.

Subsequently, the team discovered a strong correlation between the habitats of the greenfin darter and the type of rocks present. The southern half of the Tennessee River Basin consists of hard, tightly packed rocks, resulting in turbulent (湍急的) waves in the rivers that flow through it. This characteristic may be favored by the greenfin darter. As a result, the team assumed whether the distribution of greenfin darter habitats had been influenced by the changing rock types, as the rivers eroded the land over time. To test this assumption, the researchers developed a simulation model. Remarkably, the results confirmed their assumption.

1. What is new about the MIT study?

A．It finds river erosion can enhance biodiversity.

B．It further proves the mechanisms of river erosion.

C．It proves the geographical features of biodiversity.

D．It classifies a type of fish called the greenfin darter.

2. What can we learn about the greenfin darter?

A．Their appearances vary between families.	B．Their genetic constitutions have diversified.
C．They prefer the deep and slow-flowing river.	D．They go extinct in the changing landscape of rivers.

3. How did Near help the researchers reach their conclusion?

A．By creating an evolutionary tree of the fish.

B．By offering the fish’s genetic data.

C．By reasoning out the time the fish evolve and separate.

D．By analyzing the genetic similarity between different fish.

4. What is the best title for the text?

A．River Erosion Can Shape Fish Evolution	B．Genetic Change in the Greenfin Darter
C．Evolutionary Tree Analysis of the Greenfin Darter	D．The Impact of Climate Change on Fish Diversity

7 . Birders get nervous when they see landscapes covered in wind turbines (涡轮机). When the wind gets going, their blades (叶片) can turn around at well over 200km per hour. It is easy to imagine careless birds getting cut into pieces and wind turbines do indeed kill at least some birds. But a new analysis of American data suggests the numbers are negligible, and have little impact on bird populations.

Erik Katovich, an economist at the University of Geneva, made use of the Christmas BirdCount, a citizen-science project run by the National Audubon Society. Volunteers count birds they spot over Christmas, and the society gathers the numbers. He assumed, reasonably, that if wind turbines harmed bird populations, the numbers seen in the Christmas Bird Count would drop in places where new turbines had been built. Combining bird population and species maps with the locations and construction dates of all wind turbines, he found building turbines had no noticeable effect on bird populations.

Instead of limiting his analysis to wind power alone, he also examined oil-and-gas extraction (开采), which has boomed in America over the past couple of decades. Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon. When drilling happened in migration centers, feeding grounds or breeding locations, bird numbers instead dropped by 25%.

Wind power, in other words, not only produces far less planet-heating carbon dioxide and methane than do fossil fuels. It appears to be significantly less damaging to wildlife, too. Yet that is not the impression you would get from reading the news. Dr Katovich found 173 stories in major American news media reporting the supposed negative effects that wind turbines had on birds in 2020, compared with only 46 stories discussing the effects of oil-and-gas wells.

1. What does the underlined word“negligible”in paragraph 1 mean?

A．Insignificant.

B．Inaccurate.

C．Inconsistent.

D．Indefinite.

2. What is Dr Katovich's conclusion based on?

A．Previous studies.	B．Relevant data.
C．Reasonable prediction.	D．Experiment results.

3. What message does paragraph 3 mainly try to convey?

A．Oil-and-gas extraction has expanded in America.

B．Birds are heavily dependent on rivers and ponds.

C．Many factors lead to the decline of bird populations.

D．Well drilling poses a serious threat to birds' survival.

4. Which of the following may Dr Katovich agree with?

A．Wind turbines could share the sky with wildlife.

B．More evidence is needed to confirm the finding.

C．Wind power will be substituted for fossil fuels.

D．Wind turbines deserve wider media coverage.

9 . At The Rachael Ray Foundation^TM (RRF), we’re pretty big animal lovers. As a part of our work, we support a wide variety of organizations that do good for animals, from rescue to care and more. Get to know a few of them and the work we do together.

Pittsburgh Aviation Animal Rescue Team

RRF helped enable Pittsburgh Aviation Animal Rescue Team (PAART) to purchase a new and bigger plane for its rescue missions which bring animals from danger to safety. Whether it be flying dogs in overcrowded shelters to new homes, saving animals caught in the path of natural disasters, or bringing supplies to shelters in need, the brave PAART pilots are always ready to help.

National Disaster Search Dog Foundation

National Disaster Search Dog Foundation (SDF) works to find and train shelter dogs who have the talent and drive to become search and rescue animals. RRF supports SDF’s efforts to identify and transform rescued dogs into rescuers, to provide lifetime care for these dogs and to find homes for all dogs who enter the SDF training program.

Rachael Ray Save Them All Grants

This is a program administered by Best Friends Animal Society (BFAS) to support Best Friends’ network partners in their lifesaving efforts. The money has been awarded to organizations across the country to fund initiatives such as adoption drives and shelter intake prevention efforts.

North Shore Animal League America Disaster Relief Grants

This program, administered by North Shore Animal League America (NSALA), provides money for animal welfare organizations impacted by disasters. RRF is proud to help NSALA in its efforts to identify needs in disaster situations and provide targeted, effective relief.

1. What is special about PAART?

A．It provides necessities for-animals in need.	B．It conducts animal rescue missions by plane.
C．It is supported by the Rachael Ray Foundation.	D．It assists in finding adopters for rescued animals.

2. Which organization is devoted to training shelter animals to do rescue work?

10 . People have always believed that nature is good for health and happiness. According to scientific studies, being in nature makes people less stressed. In a recent experiment in Japan, one group of people were asked to walk through a forest while another group had to walk through a busy city.     1    . However, researchers found that after the walks, the people who had walked in the forest had better moods, less anxiety and even lower blood pressure. So the experiment showed that it was being in nature that helped people feel less stressed, not just the walk.

Gregory Bratman from Stanford University in the United States found in experiments that a walk in nature could have important cognitive (认知) benefits, improving a person’s memory and creativity.     2    . Teachers find that when children are enjoying the natural world, their awareness and creativity are improved, along with their reasoning and observational skills.

Why does being in nature bring so many benefits for us?     3    , so we have an instinctive (本能的) love for it. Even just looking out of the window at a beautiful tree can help us feel less stressed.

Scientists also think that being in nature helps our brain recover from a lot of activities that we usually do during the day such as working on math problems or using our cell phone.     4     — putting all our attention into one thing, which can make us feel tired. But when we are outside, we use undirected attention. We see an interesting cloud or a beautiful flower, and our attention moves quickly and easily from one thing to another. So being in nature gives our brains the chance to rest.

    5    . For many of us, nature is something we can enjoy just by walking out of our door. So enjoy the nature around you!

A．The walks were equally long and hard

B．Regular workouts are surprisingly helpful

C．One idea is that human beings come from nature

D．Nature’s benefits have been scientifically confirmed

E．In these activities, we use a lot of directed attention

F．Being in nature increases people’s mental health as well

G．We can see this in schools where outdoor learning has been introduced
