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 . 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.

4 . 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.

Common sense about fitness in the book:

·The key muscles to work for an injury-free body

·How to tell how much weight is suitable for you

·How to strengthen the bones most likely to break

·How to take pressure off your knees when walking or running

·Why you’ll want to apply heat to sore joints before you exercise

Four total body workouts in the book:

·Build bones

·Fight diseases

·Improve balance

·Strengthen muscles &Increase muscle power

Get a copy, start training, and then you’ll discover a whole new self.

5 . 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.

7 . We all want to keep fit and stay healthy, but a few things may prevent it: laziness, a busy schedule, and maybe even a limited spend.     1    . You can even make a bit of money on a few of these activities.

Babysit.

If you have your own kids, you’ll probably agree that looking after kids can help keep you fit. If you don’t, you can experience the wonderful world of toddlerhood by volunteering or signing up for a babysitting job. The best ages to babysit are those toddler years (2 through 5). Why?     2    .

Care for your yard.

    3    . Work on your yard all year long and you’ll have more than your heart going — best exercise of all is to push that lawnmower (除草机) around especially if you have a large lawn. Or even better, put in your own waste water system. All that digging should be great for upper body strength and patience.

    4    .

Have you checked your storeroom, basement and kitchen lately? Well, moving small items from their storage areas and turning them into boxes for sale, donation pick-ups or just further storage will get your blood exciting. Even just pushing around a dust cleaner, or sweeping your garage floor should oil your joints (关节).

Use someone else’s sports or exercise equipment (设备).

Have you checked under your bed lately? All around the nation, there is a flood of unused exercise equipment sitting around in garages and hiding in spare rooms and basements.     5    — if not at your own home, they could be sitting somewhere in a friend’s or relative’s home, sadly unused. It may be a good idea to reuse them.

A．Be your own gardener

B．Volunteer or get active work

C．Clean out or organize your house

D．Actually there are some free ways to move your body!

E．You could have these things right under your very nose.

F．It doesn’t really take much to get yourself into better shape.

G．In that case, you have to carry, lift, run and follow them around all day.

8 . Everywhere I look, there are new buildings under construction. The neighborhoods that I knew as a boy, filled with beautiful old buildings, have mostly disappeared, and in their place, modern, high-rise buildings have appeared. There is good reason for this. Residents want all the conveniences of modern living. However, how can our children understand and maintain their cultural identity if we erase so much of the physical evidence of it?

The arguments for preserving historic buildings are not simply about an emotional attachment to the past. There are also good economic arguments in favour of preservation. The renovation (修缮) and preservation of historic districts can become an economic engine, drawing tourists and small businesses to the area. For example, in Dubai, the historic Al Bastikiya district draws thousands of tourists every year from all over the world. It also attracts local residents, eager to learn about their city's past.

Some have argued that historic preservation is too expensive, but many recent projects have demonstrated that this is not necessarily the case. In fact, renovation of an existing structure for adaptive reuse can cost about £40 per square metre less than even the most basic new construction, while preserving the beauty of the original building. And, although it is often claimed that old buildings have a more significant environmental footprint than new construction because they aren’t very energy efficient, architects and environmental experts maintain that the greenest building is the one that is already built. New construction almost always has a more serious environmental impact (影响) because it requires the use of all-new materials that must be transported, often over long distances, instead of recycled materials that are already on site. We recycle so many other things. We can and should recycle buildings, too.

Historic preservation is an option that opens many possibilities; demolition (拆毁), in contrast, is irreversible. Once these treasures are lost, they are lost forever, an important link in our heritage that can never be recovered.

1. What drives people to replace old buildings with new ones?

A．Their dislike of old buildings.	B．Their pride in cultural identity.
C．Their concern about young generations.	D．Their desire for modern comforts.

2. What does the example of Al Bastikiya show?

A．Historic renovation costs much money.

B．Local governments support small businesses.

C．Historic preservation brings economic benefits.

A．It uses green materials.	B．It damages architectural beauty.
C．It reduces enviromental impact.	D．It worries environmental experts.

4. What is the author’s attitude towards historic preservation?

A．Positive.

B．Doubtful.

C．Disapproving.

D．Objective.

9 . It is no secret that play-based learning improves the cognitive, physical, social, and emotional well-being of children. Researchers now believe that certain board games, like Chutes and Ladders and Monopoly, can also help enhance their math skills.

The team at Pontificia Universidad Católica de Chile in Santiago, Chile, came to this conclusion after analyzing the results of 19 studies. They were conducted between 2000 and2023. All but one of the studies focused on the relationship between math skills and board games.

In these studies, kids aged 3-9 played board games under the supervision (监督) of teachers or trained adults. The 20-minute sessions were held twice a week for about six weeks. In some cases, one set of kids (the intervention group) played number-centric board games, while the other (the control group) played board games that did not require math skills. in other studies. both the intervention and control groups played number-based games. They were, however,   given different games, like Monopoly and Dominoes.

The participants’ math skills were assessed before and after each study. The researchers looked for improvement in four key categories. They included the ability to name numbers and demonstrate simple number knowledge-such as “nine is greater than three.” Changes in the kids’ abilities to add and subtract and their interest in math were also noted.

The results of the study were published in the journal Early Years on July 6, 2023. It revealed that playing board games helps improve the children’s math skills in over half of the four areas. Additionally, nearly a third of the children in the intervention groups scored higher on math tests than those in the control groups.

The researchers hope their findings will inspire the creation of new board games specially designed for classroom learning. Meanwhile, boost your math skills by organizing a game a night or two with family and friends this summer—it all adds up!

10 . Eric Ashby’s fascination with nature began at an early age. His first article, Bird Photography: an Ideal Hobby for Boys, was published when he was just 16 and illustrated with photographs that he’d taken.

His interest in photography had been sparked four years earlier in 1930, when the wildlife photographer Cherry Kearton came to Southsea, Ashby’s home town, to present a show of his work. The 12-year-old Ashby saw the show and immediately started saving his pocket money to buy a camera for filming wildlife in the nearby New Forest. But Ashby’s films did not reach the public due to the World War II.

In 1953, he and his wife Eileen moved to Badger (獾) Cottage, in the heart of the New Forest. It was here that Ashby perfected the techniques that would make him famous through the new medium of television. His patience and technical knowledge allowed him to film badgers at their holes during daylight — the first time this behaviour had ever been captured on camera.

In 1961, at the age of 43, Ashby finally got his big break, when the BBC showed his 45-minute film The Unknown Forest. The film had taken four years to make and received a very positive response from viewers. The nature writer Richard Mabey was hugely impressed and remarked that the film “changed the standards for home-grown wildlife documentaries”.

After the film was shown, he was given the nickname “the silent watcher”. The nickname not only stuck, it became the title of his second film.

In 1963, Ashby made the first British wildlife film in colour, although it took four years before The Major appeared in its full glory, as the BBC did not broadcast (播放) in colour until 1967.

He was awarded the Royal Geographical Society’s Cherry Kearton Medal and Award in 1975 and in 1992 received an MBE. He died, aged 85, on 6 February 2003, but his legacy lives on.
