3 . Banff National Park is home to an amazing wildlife population. But the busy Trans Canada Highway that cuts through the park is a hazard to the lovely animals. To address the problem, Banff first put-up wildlife fencing on either side of the highway to discourage animals from entering the busy road. Then, since 1996, they’ve opened six wildlife overpasses and 38 underpasses to help the animals cross the highway in safety. I was fortunate to visit Banff’s Red Earth Overpass with Trevor Kinley, the project manager with Parks Canada. He told me that so far, they have documented 10, 000 safe animal crossings on this overpass alone. “ Some animals have learned how to use the crossings much more quickly than others. Black bears are the fastest learners, followed by deer. Wolves and lions take the longest to work out how to use them, ” Kinley said, laughing. “ But those animals that are slower to adapt are usually more capable and determined at figuring out the safest way to cross those overpasses and underpasses. ”

There is some criticism (批评) that channeling so much wildlife into a few bridges and tunnels is like making a trap for the animals, offering big animals an easy meal on either side. “ But research has shown that this is not the case, ” Kinley assured me. “ There are no more killings around the crossings than there are anywhere else in the park. ”

Walking over the Trans Canada and then walking underneath through one of the tunnels, I was amazed to see the fresh tracks of black bears, wolves, deer and many kinds of smaller animals. Somehow, all these animal footprints made me so happy, knowing that all this wildlife was passing safely under and over the longest road in Canada.

Hopefully, the success of the wildlife crossings in Banff will continue to inspire similar solutions around the world, where human pressure on wildlife continues to grow.

3. What are the critics worried about?

A．There are too many bridges and tunnels.	B．Many animals will not use the crossings.
C．More killings might happen at the crossings.	D．Illegal hunting might be encouraged in the park.

4. How does the author feel at the end of the visit?

5 . Accents are an important part of our identity. An accent gives clues about who we are, and the community we belong to or wish to belong to.     1    

What is the difference between accents and pronunciation?

Accents are about localized ways of speaking a language. A French person may speak English flawlessly (完美无瑕地), just with a French accent.     2     However, pronunciation is something that — as a learner— you can get right or wrong. If your pronunciation is correct, you can communicate effectively with others whatever your accent is.

    3    

If you think back historically people were much more localized with generation after generation of families living in the same small villages and few people traveled out of that area during their lifetimes. So over many generations differences in accent emerged and became very distinct to particular areas. Mountainous villages that are not easily accessible often develop very strong and distinctive accents.

How important is it to get an accent right?

If you’re moving to a certain part of a country, you might want to integrate better with your new community.     4     That’s because it shows a sense of belonging to the community you are trying to fit in with.

How to improve your accent?

    5     And then learners should consider which sounds exist in the language you’re learning and then spend some time in front of the mirror practicing moving your tongue and mouth to get those new and different sounds. And learners should be aware of stress and tone, which can sometimes even change the meaning of words.

A．Where do accents and pronunciation emerge?

B．They’re also important for those learning a new language.

C．Try to adapt your speech to sound more like the locals’ speech.

D．The best way is to learn the specific accent of that region.

E．Where do different types of accents come from?

F．That’s fine because there is no wrong or right with an accent.

G．Learners should first think about which sounds don’t exist in your native language.

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

I’m not Chinese, but I love Chinese New Year. There are many fun New Year     1     (celebrate), but nothing quite matches the excitement of the lion dance which can wake up the spirit     2     (complete).

The sound of the drums,       3     you can feel throughout your entire body, is quite inspiring. The two performers are very flexible. But it is actually very difficult as the lion head is very heavy and being the     4     (low)part of the lion is tiring as he has to bend his back and also carry     5     person in front sometimes. The lion head is made with paper over a bamboo frame,       6     (cover)in gauze (纱布), and decorated with beautifully-colored materials.

The lion dance     7     (believe)to have first appeared in the Qianlong Emperor's dream during his Southern tour, and he ordered an animal     8     (make)in the likeness of his description and used in festivals from then on.

I love all about the lion dance. The other day, I saw a film about a left-behind teenager who insisted on pursuing his dreams despite difficulties and     9     (succeed)in lion dance. As Master Xu translates: “Heaven has made us talents; we’re not made     10     vain.”

7 . The past few years have been difficult for 13-year-old Adeola Abraham. In 2020, the teen was diagnosed with a rare blood disorder, and he survived a successful bone marrow transplant (骨髓移植) and rounds of chemotherapy (化疗). Thankfully, Adeola is now out of the hospital. During his recovery, he found out that he had qualified for a once-in-a-lifetime opportunity to ask for a dream wish from Make-A-Wish Mississippi. While many teens would choose a memorable Disney trip, meet a favorite figure or get a PlayStation, Abraham instead chose to feed the homeless in his local community.

The Make-A-Wish Foundation is famous for brightening the lives of children suffering from critical illnesses by meeting their wishes. A wish typically falls into three categories: a wish to have something, go somewhere or meet someone. Abraham’s charitable wish to give came as a surprise to the organization. Linda Sermons, a Make-A-Wish Mississippi representative, said that Abraham’s generous wish was the first of its kind in the organization’s 35-year history. She was impressed with the teen’s maturity and sense of sympathy.

Make-A-Wish Mississippi approved of the teen’s wish in a big way. They created a service named after the teen, called Abraham’s Table, which would provide free meals to the homeless every month for the next year. Local businesses generously donated food and supplies, and receivers gathered in Jackson’s Poindexter Park for the meals. Abraham and his proud mom personally attended and handed out the food. Abraham’s Table fed more than 80 people at its first event. Abraham said it warmed his heart when the receivers came back to thank him for the meal he provided.

Abraham now wants to inspire other teens to get more involved in local charities. He also wants to continue his mission of helping others by starting his own nonprofit that helps those experiencing food insecurity.

1. What made Abraham a remarkable boy?

A．His exceptional choice for a dream wish.	B．His great sufferings from a critical disease.
C．His special qualifications for a dream wish.	D．His successful survival from a blood disorder.

2. What can we learn from Paragraph 3?

A．Eighty people or so benefited from Abraharn’s Table.

B．Abraham’s act of kindness received positive reaction.

C．The organization provided financial help for the homeless.

D．The local businesses were greatly appreciated by the receivers.

3. According to the passage, which words can best describe Abraham?

A．Energetic and determined.	B．Mature and intelligent.
C．Sympathetic and selfless.	D．Generous and cautious.

4. Which of the following can best describe the story?

A．Hard work always pays off.	B．It’s a blessing to be a giver.
C．Actions speak louder than words.	D．Miracles often occur in bad luck.

8 . The Best National Parks to Visit in Winter

While most parks tend to draw families in the summer and fall, there are also ideal spots for adventurous winter trips.

Yellowstone National Park, Wyoming

The country’s oldest and best-known national park takes on an almost otherworldly atmosphere in winter: the air filled with rolling steam, the strong colors of hot springs, the surrounding white landscapes, let alone the impressive wildlife during this time, like bison, wolves, and playful red foxes. Just book a guided hiking tour to get a ranger’s perspective on the park and local people.

Joshua Tree National Park, California

With its giant red rocks and unique trees, you’ll feel like stepping onto a foreign planet as you spend hours hiking the Panorama Loop or Maze Loop. The park is recognized as an International Dark Sky Park, featuring virtually zero light pollution and the country’s best views of a starry sky.

Grand Canyon National Park, Arizona

A significantly lower number of visitors in winter means you can take in unblocked views of the South Rim, and get to see the rare beauty of the Grand Canyon dusted with snow. For those adventurous and daring, it is recommended to hike the Bright Angel Trail and take the chance to see the canyon’s wintertime wildlife, including mule deer, elk, and bald eagles.

Virgin Islands National Park, St. John

Surprise! Not all wintertime national park trips need to involve snow. Virgin Islands National Park is most famous for its white-sand beaches. You can also hike inland to visit old sugar plantations, or venture out to the water to swim along with sea turtles and manta rays. You will definitely enjoy a different winter here.

1. Which park will one choose if he/she is interested in stars?

A．Yellowstone National Park.	B．Joshua Tree National Park.
C．Grand Canyon National Park.	D．Virgin Islands National Park.

2. What do we know about the Grand Canyon National Park?

A．We can have a poor view of the South Rim there.	B．It lies in an area with rolling steam and hot springs.
C．There is a slight decline in visitor numbers in winter.	D．The Bright Angel Trail is challenging in cold weather.

3. Which activity is mentioned in all of the parks?

A．Hiking.

B．Skiing.

C．Swimming.

D．Hunting.

9 . The SNAG stands for stereotyped nature-inspired aerial grasper and it’s a 3D-printed bird robot with claws. It can fly, stay on various surfaces catch and carry objects, just like the mighty falcon（隼）that was used as the source of inspiration in its development.

Each leg of the SNAG has two motors, one for helping it move back and forth, and the other one for grasping. Twenty printing attempts were necessary for the robot to finally reach its current structure, but it was worth it. Now, according to researchers, the flying machine has an impressively strong and high-speed clutch（离合器），being able to land and wrap its claws around a branch in about 20 milliseconds. SNAG has ankles lock, and there’s an accelerometer （加速计）on its right foot that reports that it’s landed while triggering（触发）a balancing process to stabilize it.

Scientists have already conducted several tests with the robot in rural areas and on different surfaces. In all the situations, the SNAG was able to catch objects thrown by hand, such as bean bags, a tennis ball, and more.

As for the applications of the bird-like robot, the SNAG can get attached to drones（无人机）and be used for search and rescue missions, wildfire monitoring, to offer just a few examples. Another great application is environmental research, with the SNAG also featuring a temperature and humidity（湿度）sensor. By using a robot that can act like a bird, you can unlock new ways of studying the environment, as explained by William Roderick, mechanical engineer and one of the researchers involved in the project. Now scientists are moving on to improving the robot’s situational awareness and flight control.

This isn’t the first time that nature has inspired groundbreaking technologies. We also wrote a piece recently about the F-SAM micro drone, which was inspired by the flight of samara（翼果）seeds, also known as “twisters” which have a special way of spinning down to the ground.

1. What gave the researchers inspiration for the SNAG’s development?

A．The plane.	B．The falcon.
C．The micro drone.	D．The samara seeds.

2. What’s the function of the accelerometer on the SNAG?

A．To balance the SNAG in flight.

B．To change the SNAG’s flying speed.

C．To keep the SNAG’s feet in balance.

D．To make the SNAG steady on a surface.

3. What does Paragraph 4 mainly tell us about the SNAG?

A．The SNAG has huge potential for practical use.

B．The SNAG has a long way to go before being used.

C．The SNAG will be helpful in putting out forest fires.

D．The SNAG is sensitive to temperature and humidity.

4. What may be one disadvantage of the SNAG right now?

A．It doesn’t know its situation well.

B．It can’t fly fast enough in the air.

C．It is easily broken by the branches.

D．It can’t catch objects with smooth surfaces.

10 . Many orb weaver spiders have yellowish stripes or spots on their undersides for a good reason. That color yellow attracts bees and flies into a spider’s web, a new study suggests.

Orb weaver spiders get their name because they spin and sit on circular webs. But these spiders and their bright colors seem contradictory. Why would a spider look so noticeable? In the new study, researchers examined if yellow coloration on a species of golden orb weaver spiders (Nephila pilipes) attracts their flying insect prey. Found across Asia, this spider sits on its web day and night with its underside facing open space. The team found more than 250 female N. pilipes in the wild. They removed each female and either left its web empty or replaced it with a cardboard spider. These cardboard models had paper stripes of yellow, blue or black color stuck to them.

After almost 1,800 hours of video recording the webs, the team found that during the daytime, the yellow-striped model that looked like a real N. pilipes attracted more than twice as many insects, including bees and flies as any other fake spider or empty web. What's more, the yellow color worked just as well at night attracting moths, the scientists reported.

The team then searched online zoological databases for associations between yellow markings and prey attraction in orb weaver spiders. Surveying dozens of distantly related species showed that yellow stripes or spots were more likely to have evolved in orb weaver spiders that sit on their webs in open, bright spaces, where visual baits may be more effective.

Scientists don’t yet know why insects are attracted to yellow stripes on orb weaver spiders. Perhaps the prey mistake a spider for a yellow-flecked flower, a hypothesis (假说) supported by the fact that most prey attracted were pollinators (传粉者).

1. What made the scientists confused about orb weaver spiders?

A．Their name.

B．Their prey.

C．Their coloration.

D．Their webs.

2. How did the scientists do the study?

A．By finding wild male and female N. pilipes.

B．By filling each web with a cardboard spider.

C．By studying the stripes on female N. pilipes.

D．By using fake spiders or leaving the web empty.

3. What did the scientists most probably conclude after watching the videos?

A．Insects knew how to avoid an empty web.

B．The spiders’ stripes could attract insects.

C．Insects could be attracted to dark colors.

D．Yellow markings didn't function at night.

4. What is the best title for the text?

A．Yellow Stripes Work for the Spiders Hunting for Food

B．Yellow Stripes on Orb Weaver Spiders Have Evolved

C．Stripes and Spots can Easily Draw Much more Insects

D．Preys are Drawn to Spiders on Circular Webs Quickly
