Mary waited anxiously for her turn in the empty dressing room. Never had she been so nervous before. This competition was of vital importance to her comeback. “If I can win today,” she said to herself, “I can dance on the national stage next month.” Three months ago, her left arm was seriously injured in a car accident. After the medical treatment, she began to recover slowly. She practiced over and over again in order to regain her dancing skills.

“Hi, Mary,” in rushed her friend Jessica. “How is your arm? Is it going to influence your performance?”

“I guess it can be tolerated for I am to win the match.” said Mary with a determined look.

“Admirable! But I hear that a girl called Linda is really gifted and strong. She can be your real well-matched competitor. Come on!”

After Jessica left, Mary decided to practice her most difficult spin (旋转). “If I don’t try harder. I won’t grasp this chance.” She thought. But her arm began to hurt, making her worried. “Mary, what makes you think you have a chance tonight?” she said to herself. After the pain was gone, she continued to warm up.

A slim girl hurried in and put down an equipment bag on the chair. Then, she took out her dance dress quickly and put it on skillfully. Seeing Mary, she smiled politely and said “Hi, I’m Linda. I am the next one!” Mary nodded in reply but felt uncomfortable. “This is just my competitor. Because of her, I may lose tonight.” Her mind was wandering when Linda let out a scream, “Oh, God, I can’t find my music tape!” Linda searched her bag but in vain. “It may be missing on the way.” With these words, she then rushed out.

4 . Heman Bekele, a 14-year-old student from Virginia, has created a cheap soap that could potentially help fight 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 on October 10, 2023.

At age 4, Heman moved to America from Ethiopia, where he always saw people constantly working under the hot sun. While he considered ideas for the competition, it struck him that so many people in his hometown were unaware of the risk of sun exposure. The recollections fueled his decision to focus his research on skin cancer.

In June 2023, he was selected as a top-ten finalist and paired with 3M product engineering specialist Deborah Isabelle to develop and test a physical prototype (原型) of his idea. It took the pair four months of trial and error to create “Skin Cancer Treating Soap” (SCTS). The bar contains chemicals that restore the body’s dendritic cells (树突细胞) killed by cancer cells. Once reconstructed, dendritic cells, the body’s first line of defense against cancer and infections, are capable of fighting against cancer cells. SCTS, which costs just 50 cents a bar, still has to undergo clinical trials. The process could take over five years.

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.

“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 experts and show my project to judges was an exciting prospect (前景). I am passionate about finding sustainable solutions to global problems, and I hope to inspire others to do the same.”

5 . Nanako Hama was holding a light envelop. When he tore it open with care, locks of hair emerged. Many strangers send Hama locks of their hair, hoping to recycle it.

People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change. But hair possesses such useful qualities that it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks.

Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil. “Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier. “That’s because its rough (粗糙的) sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.

In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney in Australia, found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene, a type of plastic that’s typically used to clean up floating oil. Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen, a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.

“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes — for oil and soil,” Hama says.

1. How does the author introduce the topic in paragraph 1?

A．By detailing the background.	B．By presenting a scene.
C．By describing the usage of hair.	D．By praising an environmentalist.

2. What purpose can the mat serve?

A．Fertilize the soil.

B．Prevent oil leaks.

C．Take in harmful gas.

D．Clear the sea of oil.

3. What makes hair special in its innovative use?

A．Its color and strength.	B．Its length and amount.
C．Its weight and flexibility.	D．Its outside and component.

4. Which best describes the future of hair waste as fertilizer?

A．Uncertain.

B．Promising.

C．Doubtful.

D．Uncontrollable.

9 . All the hard work that you’ve spent making strong passwords, combining pet names with numbers, symbols and birthdates could all soon be for nothing as a new artificial intelligence (AI) model achieves a 95% accuracy of understanding keystrokes (按键).

At least that’s the extreme view of a team of British researchers. Using a deep learning model, they were able to steal data from a laptop’s keyboard using a microphone to understand what is being typed. This, in theory, would allow hackers who were able to gain access to your laptop to obtain what is being typed including messages and passwords.

The first step for this attack to work is by recording the keystrokes on someone’s keyboard. This is needed to train the algorithm (计算程序). While this could be done from the laptop’s microphone, it could equally be achieved by placing a smartphone near the computer. By pressing 36 keys on a modern MacBook Pro 25 times each and recording the sounds produced, the researchers gained a full set of training data. This information is turned into waveforms to show identifiable differences between each key. With this information in hand, they could then build a machine-learning model to understand which of these waveforms lines up with which key.

“If you get enough data, a model can be built pretty easily,” Oli Buckley, a professor of Internet security. “If it works on one keyboard, it will likely work on the next. The MacBook has a nice, quiet keyboard, so the idea is that if it works on something quiet, it will have a wide-reaching ability on louder keyboards”.

While this all sounds pretty scary, not to mention a new form of hacking (侵入) to look out for, it isn’t quite as worrying as it sounds.

“A good sample of data is needed for it to work, so this changes if you’re using a Dell, a MacBook or an external keyboard. Also, factors change. Some people type louder and harder, or my keyboards full of cat hair so that impacts things slightly”, says Buckley.

1. What is paragraph 3 mainly about?

A．Why protective steps are needed.

B．Why a set of training data is vital.

C．How you document secret information.

D．How hackers gain data from targeted computers.

2. What does the underlined word “it” in paragraph 4 refer to?

A．The keyboard.

B．The model.

C．The data.

D．The computer.

3. What’s the author’s attitude toward British researchers’ view?

A．Concerned.

B．Agreeable.

C．Negative.

D．Objective.

4. What do Buckley’s words imply in the last paragraph?

A．AI understands exactly what you’re typing.

B．Purchasing expensive computer is necessary.

C．Cats play an important role in privacy protection.

D．Building an accurate dataset through keystrokes is not easy.

10 . Five years ago, French navy officer Jérôme Chardon was listening to a radio program about the journey of the bar-tailed godwit, a bird that migrates 14,000 kilometers between New Zealand and Alaska. Chardon understood how treacherous the journey would be, as heavy storms frequently hit Pacific island communities. Yet, somehow, bar-tailed godwits routinely pass through the area uninjured. Chardon wondered whether learning how birds traveled could help coastal communities avoid natural disasters.

This past January, a team from France’s National Museum of Natural History (NMNH) began experiments designed to test Chardon’s idea. Researchers with a project led by Frédéric Jiguet from NMNH equipped 56 birds of five species with cutting-edge animal tracking technology. The team members were ferried to remote islands in French Polynesia, where they attached tags (标签) using tracking technology. These tags sent the birds’ locations to the International Space Station, which bounced the data back to scientists on Earth who could then follow the birds — waiting to see how the birds responded to natural disasters.

The project is focusing on birds’ ability to hear infrasound, the low-frequency sound humans cannot hear but that the researchers believe is the most likely signal birds would use to sense storms and tsunamis (海啸). In a 2014 study, scientists tracking a kind of golden-winged birds in the central and southeastern America found that the birds flew up to 1,500 kilometers to escape from an outbreak of tornadoes (龙卷风) that killed 35 people. The birds fled at least 24 hours before any extreme weather hit, leaving the scientists to believe that they had heard the storm system from more than 400 kilometers away.

The team plans on tagging hundreds more birds across the Pacific to prepare for a potential tsunami. “I think if there’s one wave that spreads across islands, we can get data from different species at different locations,” says Jiguet. “That will say it’s worth continuing to tag and to develop local systems to better analyze this. There are chances that we will develop a bird-based tsunami early warning system.”

A．Strange.

B．Amazing.

C．Dangerous.

D．Frequent.

2. What is the function of the tags?

A．Tracking natural disasters.	B．Distinguishing bird species.
C．Reporting the birds’ situations.	D．Guiding researchers to islands.

3. Why is the 2014 study mentioned in paragraph 3?

A．To prove an assumption.	B．To clarify a concept.
C．To present a new topic.	D．To make comparisons.

4. What might be the best title for the text?

A．How Can Birds Avoid Natural Disasters?

B．Can Birds Warn Us of Natural Disasters?

C．How Does a Warning System Function?

D．Can Birds Play a Role in Human Research?
