1 . Heman Bekele, a 14-year-old student from Annandale, Virginia, has created a bar soap (肥皂) to treat melanoma, the most common kind of skin cancer, which earned him the title of America’s Top Young Scientist and a $25,000 cash prize after his innovation won first place in the 3M Young Scientist Challenge.

“I made this soap by mixing regular medicinal soap with different cancer fighting chemicals.” Bekele said in an interview. Rather than a cure, Bekele’s soap aims to help the patient’s immune cells stay active while fighting melanoma.

While similar methods are available for skin cancer treatments, his solution is a more affordable alternative, especially for those in developing countries. Though the product is very promising on paper, studies would have to be carried out to test its efficiency in the real world.

For now, the young scientist said he has a five-year plan: At the end of it, he hopes to have created a nonprofit organization where he can provide fair and accessible skin cancer treatment to as many people as possible. But to accomplish his goal, he would have to get his treatment through clinical trials, obtain a temporary patent and have it licensed by the Food and Drug Administration, he said.

“I applied for the 3M Young Scientist Challenge because I believe that young minds can make a positive impact on the world,” Bekele said. “I have always been interested in biology and technology, and this challenge gave me the perfect platform to showcase my ideas. The opportunity to work with 3M mentors and show my project to judges was an exciting prospect. I am passionate about finding sustainable solutions to global problems, and I hope to inspire others to do the same.”

3 . Dutch researchers have discovered that birds living in cities are using metal spikes (尖刺) to build their nests. People put these spikes on buildings in order to keep birds off their balconies, benches, and chimneys, but birds seem to be stealing them and using them to keep people away from their eggs.

The research began when, in the courtyard of a hospital in Antwerp, Belgium, biologist AukeFlorian Hiemstra found a large nest that had been built by a magpie (喜鹊). The nest was made from about 1,500 metal spikes. They were pointing outward to create a protective system around the nest.

“I just stared at it, this strange, beautiful, weird nest,” Hiemstra told BBC News. When he investigated further, he found that magpies had moved away nearly 165 feet of metal spikes that had been glued to the hospital’s roof.

After Hiemstra made this discovery, his team heard about a similar nest created by crows in Rotterdam, in the Netherlands, and another magpie nest in Glasgow, Scotland. The crows had positioned the spikes in a different way, perhaps using the metal to support the nest’s structure.

In their report, the researchers mention many kinds of birds moving spikes off buildings, but they chose to focus their study on corvids(birds from the crow family). The researchers pointed out that there have been previous studies on how corvids use everything from telephone wires to clothes hangers to build their nests. They said the use of anti-bird spikes “hints at a functional use”—meaning the birds seem to know exactly what they’re doing.

Magpies have often been seen nesting in thorny (多刺的) places, where the thorns can prevent people from attacking the small eggs and chicks inside the nest. Thorny hedges aren’t common in cities, however, so the theory is that magpies use the human-made version instead. Hiemstra calls this the birds’ “revenge”. “We’re trying to get rid of birds, but the birds are collecting our metal spikes and actually making more birds in these nests,” he said.

1. Why are metal spikes put on buildings?

A．To draw birds’ attention to the nest.	B．To prevent strangers entering.
C．To keep birds off the buildings.	D．To make the buildings more beautiful.

2. Magpies use metal spikes to build nests ________.

A．to protect their eggs and chicks	B．to decorate their nests
C．to provide a strong hold	D．to support the structure of the nests

3. What does Hiemstra think of birds’ collecting metal spikes?

A．Disappointing.	B．Appreciative.
C．Confusing.	D．Indifferent.

4. What is the purpose of the passage?

A．To introduce a new species of bird that has adapted to city life.

B．To compare different nesting habits of birds in urban environments.

C．To emphasize the negative impact of human activities on bird habitats.

D．To inform readers about birds using metal spikes to build nests in cities.

4 . The rate of childhood obesity in the U. S. has tripled over the past 50 years. The American Academy of Pediatrics (AAP) made waves this year by recommending that doctors put obese kids as young as two years old on intensive, family-oriented lifestyle and behavior plans. It also suggested prescribing weight-loss drugs to children l2 and older and surgery to teens 13 and older. This advice reflects the organization’s adoption of a more active position on childhood obesity.

Yet the lifestyle programs the AAP recommends are expensive, inaccessible to most children and hard to maintain. Few weight-loss drugs have been approved for children. And surgery has potential risks and few long-term safety data. Furthermore, it’s not clear whether interventions in youngsters help to improve health or merely add to the psychological burden overweight kids face from the society.

Rather than paying close attention to numbers on a scale, the U. S. and countries with similar trends should focus on an underlying truth: we need to invest in more and safer places for children to play where they can move and run around, climb and jump, ride and skate.

Why is it so hard to get kids moving? Experts blame the problem on the privatization of sports — as public investment in school-based athletics dwindles, expensive private leagues have grown, leaving many kids out. In addition to fewer opportunities at school, researchers cite increased screen time and a lack of safe places for them to play outside the home. New York City, for example, had 2,067 public playgrounds as of 2019 — a very small amount for its large population. In Los Angeles in 2015, only 33 percent of youths lived within walking distance of a park.

Kids everywhere need more places to play. Public funding to build and keep up these areas is crucial, but other options such as shared-use agreements can make unused spaces available to the public. These opportunities aren’t primarily about changing children’s waistlines — they’re how we keep childhood healthy and fun.

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

A．Childhood obesity is well under control in recent years.

B．Weight-loss surgery are recommended to children 12 and older.

C．AAP plays a more active role in fighting against childhood obesity.

D．Expensive as it is, lifestyle programs are practical for most children.

2. The underlined word “dwindle” is closest in meaning to ______.

A．decline

B．quit

C．increase

D．develop

3. In the author’s opinion, what measures should be taken to create more safe areas?

A．Prepare fitness equipment at home.

B．Live within walking distance of a park.

C．Promote investment in private athletics.

D．Open up playgrounds when school’s out.

4. What’s the main idea of the text?

A．Sports play an important role in children’s growth.

B．More safe areas for outdoor fun are in urgent need.

C．Family-oriented lifestyles are crucial to children’s health.

D．Medical intervention is important to ease psychological burden.

5 . Discover the Huge Health Benefits of Strength Training

One of the best ways to stay fit and healthy as you age is to do strength and power training exercises. It is known that when you are in your thirties, you will begin to lose muscle mass. This loss actually contributes to achy joints, the increased risk of injury, and the “middle-age spread” we all fear. What’s more, the older you get, the faster muscle mass loses. It means that eventually, simple tasks like getting out of a chair and climbing stairs can become more difficult.

Strength training can help you build muscles, make you strong, increase your staying power and make everyday activities easier. By combining strength and power training exercises, you’ll not only get stronger, but also improve your reaction speed. As you grow older, that’s critical because it can help prevent falls. Here is a book, Strength and Power Training for All Ages, for your reference.

9 . A wildlife photographer was waiting, hoping to get a shot of a relatively rare bird, a particular kind of heron(鹭). He’d waited several frustrating hours in the woods, but with no luck at all. Suddenly, to the photographer’s delight, a heron settled on a branch right in front of him. The photographer raised his camera and took the shot. Feeling particularly pleased, the photographer looked at the image. To his astonishment, he saw that behind the heron, his photograph had also captured a very, very rare woodpecker flying past. He hadn’t seen it, but without even trying, he’d photographed an even rarer bird than the one he was aiming for. This is an example of serendipity.

Cases of serendipity can be found in numerous fields, such as science. Back in the 1800s, a man called Wellswas at a demonstration (演示) of laughing gas. After being given the gas, the patient started laughing, as expected. But then he suddenly fell over and cut his le g rather badly. To everyone’s surprise, the man reported that he couldn’t feel any pain. Wells hadn’t been looking for it, but he’d made a medical discovery — certain gases reduce and can even almost eradicate pain. Had Wells not been there that night, anesthesia (麻醉) might have taken longer to be discovered.

Most of us can probably think of at least one example of serendipity in our own lives. Jane, a friend of mine,was trying to come up with an idea for an article but got completely stuck. Frustrated, she decided to go out to a local café. As she was sipping her coffee, she heard two people talking behind her. A man was telling a story that sounded so unbelievable that she knew it had to be true. She asked the people if she could interview them for the article. They agreed and her article turned out to be one of the top trending articles of the week.

10 . For long, Preifer Fall Trail (路线) was a most popular attraction in Big Sur. Annually, thousands of people hiked the trail. Unfortunately, the trail, along with stairs, signs, railings, an observation station and wooden bridges, was destroyed in the 2008 Basin Complex Fire. But now a new trail has risen from the burned land.

With its amazing rocky coastline and mountains, Big Sur, the writer Henry Miller once said, is “the face of the earth as the creator intended it to look.” But the landscape always suffers natural disasters. There have been three major wildfires in Big Sur in the past years. “You can still see the impacts there,” said John Hiles, a state parks repair team leader, pointing to black marks 30 feet up a huge redwood.

Parks planners designed a new track, moving the trail out of the river to reduce its impact on the environment. People from the California protection group, state parks department and the nonprofit organization put in 66,000 hours of work over the past four years. They built 160 redwood stairs and dragged hundreds of 16-foot-long redwood sticks by hand to build railings. They removed 4,150 square feet of old building stuff, enough to cover a basketball court. They used iron cables and pulleys (缆线和滑轮) to build a 70-foot long wooden bridge over the hills. “Nature is probably the best place to learn,” Hiles said. “More than any college or school, you learn so many life lessons out here.”

However, the huge Soberanes Fire s wept through the area in 2016, putting a stop to the work. When they began again in 2017, great river storms flooded the area and damaged part of Highway 1. Everybody gathered around this project. They saw the loss. They missed it. They wanted it to come back. They kept combining efforts. It’s been a long journey, but worth the wait.

1. What can we learn about Preifer Fall Trail?

A．It is an attraction rebuilt in 2008.	B．It met with many natural disasters.
C．It features man-made landscape.	D．It is an addition to a previous track.

2. How did the people reduce the impact of the trail on the environment?

A．By moving the trail off watercourse.	B．By using huge redwood sticks.
C．By recycling the old building stuff.	D．By applying iron cables and pulleys.

3. What can best describe the people’s work?

A．Limiting and typical.	B．Adventurous but smooth.
C．Mysterious and attractive.	D．Tough but rewarding.

4. What is the text mainly about?

A．The rise and fall of a hiking trail.	B．California protection projects.
C．The recovery of a lost attraction.	D．Journeys into wilderness.
