1 . As reported in the journal Nature, one system can directly remove carbon dioxide from sources ranging from flue gas (烟道气) to the atmosphere by using electricity to induce a water-and-oxygen-based electrochemical reaction. This technological achievement could turn direct air capture (捕获) from edge industry into a promising front for climate change relief.

Most carbon-capture systems involve a two-step process: First, high-pH liquids are used to separate the carbon dioxide, which is acidic, from mixed-gas streams such as flue gas. Next, the carbon dioxide is regenerated from the solution through heating or by injecting a low-pH liquid.

“Once the carbon dioxide is trapped in these solvents (溶剂), you have to regenerate it,” says Haotian Wang, assistant professor at Rice University. “There are literally no chemicals produced or consumed with our process. We also don’t need to heat up or pressurize our device, we just need to put it into a power outlet and it will work.”

Another drawback of current carbon-capture technologies is their reliance on large-scale, centralized infrastructure. By contrast, the system developed in the Wang lab is an extensible, modular, point-of-use concept that can adapt to a variety of scenarios. “The technology can be scaled up to industrial settings-power plants, chemical plants-but the great thing about it is that it allows for small-scale use as well: I can even use it in my office.” Wang says.

Also the reactor can continuously remove carbon dioxide from a simulated (模拟的) flue gas with efficiency above 98% using a relatively low electricity input. Wang notes that the process has “no carbon footprint or a very limited footprint” if powered by electricity from renewable sources such as solar or wind. “This is great news considering that renewablel electricity is becoming more and more cost-effective,” Wang says.

2 . Around 3,500 Americans ingest (摄入) batteries every year. It’s apparently such a repeating issue that even a specific hotline was built in the event of such an emergency.

And while it’s unlikely your wristwatch’s power source will ever be safe to eat, that doesn’t mean all batteries will remain uneatable-in fact, some are being designed with digestion specifically in mind.

A team of researchers at the Italian Institute of Technology recently revealed what isl being called as the world’s first fully rechargeable, eatable battery. As detailed in a paper published with Advanced Materials, the new device has made good use of some eatable materials.

“Eatable electronic devices will have major implications for gastrointestinal tract (胃肠道) monitoring, treatment, as well as rapid food quality monitoring,” reads the paper’s abstract, adding that although recent research proved the feasibility of eatable sensors and circuits, “fully eatable electronic devices and eatable power sources are still required, of which there have been very few examples.”

According to the team’s findings, their proof-of-concept battery was capable of producing 0.65 volts, which is safely low enough for the human body to handle. The ingestible could provide 48 μA of current for 12 minutes, or alternatively, a few microamps (微安) for over an hour. Such a power supply could provide enough energy for small electronics alike to eatable pill-shaped modules and other gastrointestinal procedure alternatives.

In a statement, researcher coordinator Mario Caironi explained that such a product could help power monitors for both human health conditions and food storage. Additionally, given their safety, products with stronger power could be used within children’s toys, where ingestion risk is higher.

In the team’s statement, co-author Ivan Ilic also explained that despite the battery’s relatively low power, its digestibility provides a promising example of a battery that doesn’t use any harmful materials.

5 . 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。

Having grown up in northern Arizona, I believe that the southwestern state is home     1     the most beautiful landscapes on the planet. That is, until I     2     (invite) to explore Guizhou province by an organization many years ago. There is nothing like seeing with one’s own eyes.

My father used to drag my brothers and me on     3     (fish) trips around Arizona. We would compete to catch the     4     (large) fish. On my trip to Guizhou I had the opportunity to canoe on Wanfeng Lake,     5     I enjoyed the silence and took in the surrounding karst mountains.

During my trip around     6     city of Xingyi, in Guizhou, I saw the artwork of the Bouyei ethnic group. They use dyes (染料)     7     (produce) from local plants to make clothing and blankets. Local elders still practice weaving with wooden machines and pass that tradition on to their grandchildren. The designs were ancient, and carried     8     (wise) within them.     9     (serious), I got the feeling of being home while looking at the art on display in Xingyi.

I     10     (live) away from Arizona for 10 long years, making my own living in China. I’ve managed to build a family, a career, a livelihood, and passion projects. I feel as though I have everything I need. In Guizhou, I feel at home.

6 . After decades of married life, I realized that my life was limited, and even having friends frightened me. To ease my anxiety, my husband and I explored the Blue Ridge Mountains about an hour’s ride from home. We chose a path only a couple of miles long. The process of putting one foot in front of the other started to ease my worried soul. Being with nature slowed down my racing mind. Up and down the path we went. The trees gently swayed in the wind as we enjoyed views of valleys below us.

I knew this was my way to heal. I found the Internet site Meetup, picked a group and signed up for a five-mile hike in Shenandoah National Park. All my worries came into play when meeting the hiking group. The fifteen hikers, at least ten years younger than me, started slowly, crossing many little streams on rocks. I enjoyed the tour but struggled to keep up. After a half-mile, my steps got into the rhythm. I felt a part of all that surrounded me.

I have been actively hiking since that day, walking thousands of miles, with several worn pairs of hiking boots to prove it. With my fellow hikers, I climbed Mount Le Conte at 6,593 feet. It was a challenging hike, but I made it.

I have hiked the Dingle Peninsula in Ireland with five other women, through more than a hundred miles of green hills and valleys filled with baby sheep and their mothers. I’m fortunate to have the Blue Ridge Mountains nearby. Before the pandemic, I backpacked on the AppalachianTrail, falling short of my 100-mile goal but enjoying it. I met hikers along the way, camping next to them and listening to their determination to hike the entire 2,200 miles.

I don’t intend to give up being one with nature outdoors anytime soon. We all are responsible for our peace and happiness.

7 . The 1973 horror film “The Exorcist” and “Silent Night, Deadly Night” released in 1984 were so scary that audiences left the theater up and out—throwing up and passing out, that is.

Based on this evidence after the release, it would seem to most people that horror movies are bad for people’s health. Yet experts actually argue exactly the opposite: The Halloween tradition of watching scary movies is actually good for your mental health.

“There is some research on this in psychology, but I think what’s basically been found is that there’s a benefit to recalling fears in your mind,” Matthew Strohl, the author of Why It’s OK to Love Bad Movies, told Salon. “You can gain a sense of distance from them. You feel you can conquer them through this sort of exposure, as it were, by repeatedly putting yourself in a position where you have to engage with them. But because it’s in a fictional (虚构的) artistic context, you can deal with them.”

Frank T. McAndrew, who has studied how places can “creep” people out (让人害怕)—researched on the science behind how horror movies are in many ways ideal as a specific vehicle for meeting this need to be scared.

“That is kind of born with us,” McAndrew pointed out. “We like stories. We like to learn through the experience of other people. We learn valuable lessons that might be kind of costly to learn on our own. So we are attracted by horror movies and horror experiences because by watching other people deal with scary things, we can mentally practice strategies that will make us better prepared for dealing with that ourselves in the future.”

Whether it is turning down the movie’s volume, covering your eyes, or reminding yourself that it is just a movie, McAndrew said “that kind of playful engagement with fear can not only help people avoid fainting from horror in face of a horror movie, but also handle the pressure and anxieties of the real world.”

1. How experts’ opinion differs from most people’s belief?

A．People like horror movies.	B．Horror films are actually beneficial.
C．Horror may cause physical discomfort.	D．Halloween tradition is watching horror movies.

2. Which statement might Matthew Strohl agree with?

A．Horror films can give people a sense of control.

B．Fears can keep people away from scary films.

C．Fears in life differ from those caused by scary films.

D．Not everyone can appreciate the beauty of fictional arts.

3. What does “That” underlined in paragraph 5 probably mean?

A．The appeal for a vehicle.	B．The need for fear.
C．The fear for some places.	D．The science behind horror.

4. In which aspect can scary film lovers perform better?

A．Studying literature and art.	B．Writing film reviews.
C．Dealing with stress and anxiety.	D．Interacting with others.

8 . How to Be More Present

Many people have a tendency to live in the past or the future. They constantly think about the past and worry about the future, and thus find it difficult to enjoy the good things in life in the here and now. You might unfortunately be one of these people.     1     Here are some tips that might help you.

Notice Your Surroundings

One way to be in the present moment is by noticing your surroundings. How often do you take time out of your day to actually look around and see what’s going on? Now close your eyes and take a deep breath.     2     When you do, it’s easier to be more present in the moment.

Be Grateful for What You Have Now

    3     If you are constantly focused on things you don’t have, you aren’t taking the time to appreciate what you have at this moment. One way to practice gratitude is to write a list of things you are grateful for and review that list on a daily basis. Try to write at least three things you are grateful for in your life right now.

Show Acceptance

If you want to learn how to be more present, you need to let go of how you think things should be and accept them for what they are.     4     Sometimes life is going to be different than how you want it to be. Practicing acceptance will help you let go of the things in your life that are out of your control.

Find Positive Social Support

The kind of social support you have in your life can also play an important role. Surrounding yourself with positive, supportive people will increase your own positivity and happiness levels.     5    

A．Then open them and really take in where you are.

B．You should focus your attention on one thing at a time.

C．You cannot control everything that happens around you.

D．This is one way to distance yourself from what you are enjoying.

E．In turn, this will allow you to focus on what is going on right now.

F．Part of living in the present moment is to appreciate what you have now.

G．So learning how to live in the moment can greatly improve your well-being.

9 . The Mona Lisa is the famous Leonardo da Vinci painting of a woman with a mysterious smile. This week, the painting gave up a secret.

Scientists using X-rays to examine the chemical structure of a small part of the painting discovered a technique Leonardo used in the work. An oil paint used for it was a special, new chemical mixture, which suggests that the Italian artist was in an experimental mood when he worked on the painting in the 16th century.

“He loved to experiment, and each of his paintings is completely different technically,”said Victor Gonzalez, a chemist who has studied the chemical element (成分) of several works by Leonardo and other artists. The researchers found a rare lead compound (铅化合物) — plumbonacrite, in Leonardo’s first layer of paint. The discovery proved that da Vinci most likely used lead oxide to thicken and help dry his paint. The paint in the study is about the thickness of a human hair, lying in the top right area of the painting.

The scientists looked into its atomic structure using X-rays, moving particles at the speed of light, permitting researchers to look deeper into the paint structure. “ Plumbonacrite is really a fingerprint of his recipe, as it’s the first time we can chemically confirm it,” Gonzalez said.

Dutch artist Rembrandt may have used a similar mixture when he was painting in the 17th century. Gonzalez and other researchers have found plumbonacrite in his work, too. Leonardo is thought to have put lead oxide powder, which has an orange color, in the oil to make it thicker and dry faster. “What you will get is an oil that has a very nice golden color,” Gonzalez said. “It flows more like honey.”

But the Mona Lisa — said by the Louvre to be a portrait (肖像) of Lisa Gherardini, the wife of a Florentine silk businessman — and additional works by Leonardo still have other secrets to tell. “What we are saying is just a little brick in the knowledge,” Gonzalez said.

1. What’s the new discovery about the Mona Lisa?

A．A new explanation of the secret smile.

B．A new chemical element used in the painting.

C．The secret of the woman in the painting.

D．The structure of the paint da Vinci used.

2. Which best explains the underlined word “fingerprint” in paragraph 4?

A．Open secret.

B．Widespread use.

C．Hidden element.

D．Long-term dream.

3. How does Gonzalez view the use of lead oxide powder in paintings?

A．It helps to make many things into paints.

B．It helps to make paints easy to deal with.

C．It helps to keep the paintings last long.

D．It helps to make paintings rich in color.

4. What can we learn about the Mona Lisa from the last paragraph?

A．It has more secrets to tell the world.

B．It’s the portrait of a silk businessman.

C．It’s well kept in bricks in the Louvre.

D．It has a mixture of different art styles.
