1 . Grizzly bears, which may grow to about 2.5 m long and weigh over 400 kg, occupy a conflicted corner of the American psyche — we revere (敬畏) them even as they give us frightening dreams. Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see, and their answer is often the same: a grizzly bear.

“Grizzly bears are re-occupying large areas of their former range,” says bear biologist Chris Servheen. As grizzly bears expand their range into places where they haven’t been seen in a century or more, they’re increasingly being sighted by humans.

The western half of the US was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans. By the early 1970s, after centuries of cruel and continuous hunting by settlers, 600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies. In 1975, grizzlies were listed under the Endangered Species Act.

Today, there are about 2,000 or more grizzly bears in the US. Their recovery has been so successful that the US Fish and Wildlife Service has twice attempted to delist grizzlies, which would loosen legal protections and allow them to be hunted. Both efforts were overturned due to lawsuits from conservation groups. For now, grizzlies remain listed.

Obviously, if precautions (预防) aren’t taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food. If people remove food and attractants from their yards and campsites, grizzlies will typically pass by without trouble. Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away. “Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits,” says James Jonkel, longtime biologist who manages bears in and around Missoula.

2 . Dogs greet other dogs nose-first, as it were—sniffing each other from fore to (especially) aft. People are not quite so open about the process of sniffing each other out. But the size of the perfume industry suggests scent is important in human relations, too. There is also evidence that human beings can infer kinship (亲戚关系), deduce emotional states and even detect disease via the sense of smell.

Now, researchers of the Weizmann Institute of Science in Israel, have gone a step further. They think they have shown, admittedly in a fairly small sample of individuals, that friends actually smell alike. They have also shown that this is probably the case from the beginning, with people picking friends at least partly on the basis of body odour (气味), rather than the body odours of people who become friends subsequently converging (趋同).

They stated their research by testing the odours of 20 pairs of established non-romantic, same-sex friends. They did this using an electronic nose and also two groups of specially employed human “smellers.” The e-nose employed a set of gas sensors to assess T-shirts worn by participants. One group of human smellers were given pairs of these shirts and asked to rate how similar they smelt. Those in the other group were asked to rate the odours of individual T-shirts on five subjective dimensions: pleasantness, intensity, attractiveness, competence and warmth. All three approaches yielded the same result. The T-shirts of friends smelt more similar to each other than the T-shirts of strangers. Friends, in other words, do indeed smell alike.

Why scent might play a role in forming friendships remains obscure. Other qualities related with being friends, including age, appearance, education, religion and race, are either immediately obvious or rapidly become so. But while some individuals have strong and noticeable body odour, many—at least since the use of soap has become widespread—do not. It is present. But it is subconscious.

B．People start to smell alike after becoming friends.

C．Many people are involved as the research samples.

D．Odour-matching may be a reason for being friends.

3. How did the researchers conduct the experiment?

A．By trying to yield the same result with three approaches.

B．By testing the odours of 20 non-romantic friends of the same sex.

C．By asking each group to rate the odours of T-shirts on five dimensions.

D．By employing e-nose and human smellers to assess the odours of T-shirts.

4. What does the underlined word “obscure” in the last paragraph mean?

A．Unclear.

B．Important.

C．Obvious.

D．Subjective.

3 . When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.

After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.

The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.

He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.

Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.

“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

1. What can we learn about John from the first two paragraphs?

A．He was fond of traveling.	B．He enjoyed being alone.
C．He had an inquiring mind.	D．He longed to be a doctor.

2. Why did John put the sludge into the tanks?

A．To feed the animals.	B．To build an ecosystem.
C．To protect the plants.	D．To test the eco-machine.

3. What is the author’s purpose in mentioning Fuzhou?

A．To review John’s research plans.	B．To show an application of John’s idea.
C．To compare John’s different jobs.	D．To erase doubts about John’s invention.

4. What is the basis for John’s work?

A．Nature can repair itself.	B．Organisms need water to survive.
C．Life on Earth is diverse.	D．Most tiny creatures live in groups.

4 . Indoor plants might look as if they just sit around not doing much, but in many ways they are the unsung heroes of the home.     1    , but studies have shown that they can promote people’s wellbeing by improving their mood (心情), reducing stress and helping their memory. What’s more, indoor plants are easy to look after and are not very expensive.

What are indoor plants?

Indoor plants, also known as houseplants or pot plants, are plants that like to grow indoors. Many of these species (物种) are not ideally suited to growing outside in the UK, especially in the winter.     2    .

Why are indoor plants good for you?

Will Spoelstra, who works at the Royal Botanic Gardens, says, “    3    . I find during the winter months, plants around the house can really lift your mood.” Several studies have backed this up and found that indoor plants can improve creativity, focus and memory. There is also research showing that pot plants can clean the air around them by removing harmful gases, such as carbon dioxide. They also remove some harmful chemicals from paints or cooking.     4    .

Which plants can you grow?

Aloe vera, peace lilies and spider plants are some of the species that are easy to grow indoors. You can buy plants from supermarkets, garden centres or online. Younger plants are often cheaper than fully grown ones, and you get to care for them as they mature — which is part of the joy of owning plants. “    5    ,” Spoelstra says. “It can bring a new interest and focus into people’s lives and help to make the link between home and nature.”

A．All plants are different

B．Not only do they look beautiful

C．There are many benefits to growing plants indoors

D．Instead, they grow better inside, where it is warmer

E．Plants like peace lilies and devil’s ivy are among the best

F．Changing the pot of your plant from time to time will also help

G．Learning about the requirements of each plant can be very rewarding

5 . As cities balloon with growth, access to nature for people living in urban areas is becoming harder to find. If you’re lucky, there might be a pocket park near where you live, but it’s unusual to find places in a city that are relatively wild.

Past research has found health and wellness benefits of nature for humans, but a new study shows that wildness in urban areas is extremely important for human well-being.

The research team focused on a large urban park. They surveyed several hundred park-goers, asking them to submit a written summary online of a meaningful interaction they had with nature in the park. The researchers then examined these submissions, coding (编码) experiences into different categories. For example, one participant’s experience of “We sat and listened to the waves at the beach for a while” was assigned the categories “sitting at beach” and “listening to waves.”

Across the 320 submissions, a pattern of categories the researchers call a “nature language” began to emerge. After the coding of all submissions, half a dozen categories were noted most often as important to visitors. These include encountering wildlife, walking along the edge of water, and following an established trail.

Naming each nature experience creates a usable language, which helps people recognize and take part in the activities that are most satisfying and meaningful to them. For example, the experience of walking along the edge of water might be satisfying for a young professional on a weekend hike in the park. Back downtown during a workday, they can enjoy a more domestic form of this interaction by walking along a fountain on their lunch break.

“We’re trying to generate a language that helps bring the human-nature interactions back into our daily lives. And for that to happen, we also need to protect nature so that we can interact with it,” said Peter Kahn, a senior author of the study.

1. What phenomenon does the author describe at the beginning of the text?

A．Pocket parks are now popular.	B．Wild nature is hard to find in cities.
C．Many cities are overpopulated.	D．People enjoy living close to nature.

2. Why did the researchers code participant submissions into categories?

A．To compare different types of park-goers.	B．To explain why the park attracts tourists.
C．To analyze the main features of the park.	D．To find patterns in the visitors’ summaries.

3. What can we learn from the example given in paragraph 5?

A．Walking is the best way to gain access to nature.

B．Young people are too busy to interact with nature.

C．The same nature experience takes different forms.

D．The nature language enhances work performance.

4. What should be done before we can interact with nature according to Kahn?

A．Language study.	B．Environmental conservation.
C．Public education.	D．Intercultural communication.

7 . 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。

I was invited to a cookout on an old friend’s farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years. A noise at a window caught my attention, so I entered it. It was a hummingbird (蜂鸟), desperately trying to escape. She was covered in spider-webs (蛛网) and was barely able to move her wings. She ceased her struggle the instant I picked her up.

With the bird in my cupped hand, I looked around to see how she had gotten in. The broken window glass was the likely answer. I stuffed a piece of cloth into the hole and took her outside, closing the door securely behind me.

When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes. I removed the sticky spider-webs that covered her head and wings. Still, she made no attempt to fly. Perhaps she had been struggling against the window too long and was too tired? Or too thirsty?

As I carried her up the blackberry-lined path toward my car where I kept a water bottle, she began to move. I stopped, and she soon took wing but did not immediately fly away.

Hovering (悬停), she approached within six inches of my face. For a very long moment, this tiny creature looked into my eyes, turning her head from side to side. Then she flew quickly out of sight.

During the cookout, I told my hosts about the hummingbird incident. They promised to fix the window. As I was departing, my friends walked me to my car. I was standing by the car when a hummingbird flew to the center of our group and began hovering. She turned from person to person until she came to me. She again looked directly into my eyes, then let out a squeaking call and was gone. For a moment, all were speechless. Then someone said, “She must have come to say goodbye.”

9 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.

Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.

“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).

Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.

Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.

1. What do solar developers often ignore?

A．The decline in the demand for solar energy.

B．The negative impact of installing solar panels.

C．The rising labor cost of building solar farms.

D．The most recent advances in solar technology.

2. What does InSPIRE aim to do?

A．Improve the productivity of local farms.

B．Invent new methods for controlling weeds.

C．Make solar projects environmentally friendly.

D．Promote the use of solar energy in rural areas.

3. What is the purpose of the laws mentioned in paragraph 4?

A．To conserve pollinators.	B．To restrict solar development.
C．To diversify the economy.	D．To ensure the supply of energy.

4. Which of the following is the best title for the text?

A．Pollinators: To Leave or to Stay	B．Solar Energy: Hope for the Future
C．InSPIRE: A Leader in Agriculture	D．Solar Farms: A New Development

10 . Live with roommates? Have friends and family around you? Chances are that if you’re looking to live a more sustainable lifestyle, not everyone around you will be ready to jump on that bandwagon.

I experienced this when I started switching to a zero waste lifestyle five years ago, as I was living with my parents, and I continue to experience this with my husband, as he is not completely zero waste like me. I’ve learned a few things along the way though, which I hope you’ll find encouraging if you’re doing your best to figure out how you can make the change in a not-always-supportive household.

Zero waste was a radical lifestyle movement a few years back. I remember showing my parents a video of Bea Johnson, sharing how cool I thought it would be to buy groceries with jars, and have so little trash! A few days later, I came back with my first jars of zero waste groceries, and my dad commented on how silly it was for me to carry jars everywhere. It came off as a bit discouraging.

Yet as the months of reducing waste continued, I did what I could that was within my own reach. I had my own bedroom, so I worked on removing things I didn’t need. Since I had my own toiletries (洗漱用品), I was able to start personalising my routine to be more sustainable. I also offered to cook every so often, so I portioned out a bit of the cupboard for my own zero waste groceries. Perhaps your household won’t entirely make the switch, but you may have some control over your own personal spaces to make the changes you desire.

As you make your lifestyle changes, you may find yourself wanting to speak up for yourself if others comment on what you’re doing, which can turn itself into a whole household debate. If you have individuals who are not on board, your words probably won’t do much and can often leave you feeling more discouraged.

So here is my advice: Lead by action.

1. What do the underlined words “jump on that bandwagon” mean in the first paragraph?

A．Share an apartment with you.	B．Join you in what you’re doing.
C．Transform your way of living.	D．Help you to make the decision.

2. What was the attitude of the author’s father toward buying groceries with jars?

A．He disapproved of it.	B．He was favorable to it.
C．He was tolerant of it.	D．He didn’t care about it.

3. What can we infer about the author?

A．She is quite good at cooking.	B．She respects others’ privacy.
C．She enjoys being a housewife.	D．She is a determined person.

4. What is the text mainly about?

A．How to get on well with other family members.

B．How to have one’s own personal space at home.

C．How to live a zero waste lifestyle in a household.

D．How to control the budget when buying groceries.
