A few weeks ago, my sister was going through her old coats and vests（背心）, seeing what was no longer needed. Although she was still in junior high school. she found ways here and there to make some extra money for her holiday shopping.

She found two vests in like-new condition and asked if I would list them in our local Facebook yard sale group. She set the price at $7 each and it wasn’t long before someone replied, wanting to buy them.

The buyer replied in a short message with broken English; it was obvious that Spanish was her native language. After a few messages back and forth, she revealed that she couldn’t drive to my house to pick up the vests because she lived on the other side of town, but asked if I would be willing to ship the vests to her instead.

I hesitated. The last week of school was so crazy busy. I barely had enough time to get from place to place, much less figure out how to wrap up these heavy vests and ship them out. I was feeling overwhelmed trying to get everything accomplished and this one extra task seemed like that straw that would break the camel’s back.

She must have sensed. my hesitation as she sent another message offering to send me a money order（汇票）to pay for the vests and the shipping costs.

A money order.

I literally froze when I read her message. It was obvious this woman wanted these items, probably for a Christmas gift for a child or grandchild. I knew if she took the time to get a money order, then mailed it to me and if I waited to get the money order then shipped the vests to her, there was a really good chance they would not arrive in time for Christmas morning.

4 . “Medicine and technology may fail us at times, but human connection grounded in love and compassion always heals（治愈）.” Those words from Dr. Vivek Murthy are relatable to many of us in the medical community who increasingly encounter individuals suffering from loneliness. There are many complex factors driving loneliness, but it is clear that positive social connections do in fact “heal”.     1     They may even prolong our life span. Here are several actions you can take to improve your social connections and support your health.

    2     For instance, a simple smile to a stranger, a friendly exchange with a store clerk, or a curious question about a pin or piece of jewelry on a colleague can enrich your daily life.

For more substantial connections, explore activities. with shared interests. Community centers, libraries and online groups are great resources. Community centers organize a wide range of activities for social connections.     3     Joining a walking group, volunteering at a food bank, or simply calling a long-lost friend can provide a sense of community and purpose.

Our deepest social connections are provided by those closest to us.     4     By engaging in open-ended conversations, we can build even more profound and supportive bonds. Such relationships are not only about the easy times; they also involve navigating challenging discussions, which should be approached as chances to learn and grow together.

    5     But by taking steps now to start to build a foundation for strong positive social connections in our future, we can make ourselves and our country as a whole healthier.

A．Deep social connections can also come with some drawbacks.

B．There may be no quick fixes to a desperate state of loneliness.

C．Loneliness ea n lead to feelings of sadness and a lack of purpose.

D．Even short, positive interactions may positively impact our health.

E．These connections greatly improve our physical and mental well-being.

F．Libraries often host book signings and lectures that encourage engagement.

G．Intentionally developing these relationships is crucial for strong social support.

5 . A starfish has five identical arms with a layer of “tube feet” beneath them. Have you ever wondered whether starfish have defined front and back ends—and if they have no heads at all? The answer, suggests new genetic（基因的）research, is the opposite. “It’s as if the starfish is completely missing a trunk,” said Laurent Formery at Stanford University. “And it’s best described as just a head crawling along the seafloor.”

Starfish belong to echinoderms with lines of symmetry（对称）radiating out from a center point, like spokes on a wheel. So the unusual animals have unique body plans（结构）arranged in five equal sections that greatly differ from the bodies of bilateral animals, which have left and right sides mirroring each other.

Starfish begin as fertilized eggs that hatch and become larvae（幼虫）that float in the ocean for weeks to months before settling on the ocean floor. There, they go through a process that transforms a bilateral body into a star shape. “This has been a mystery for centuries,” said Christopher Lowe at Stanford University.

Researchers used new methods of genetic sequencing to create an unprecedented 3D map to determine where genes were expressed as starfish developed and grew. They found that genetic features associated with the development of a head were detected all-over the starfish especially concentrated in the center of the star and the center of each “arm”. Meanwhile, gene expression for trunk sections was largely absent. This suggested that starfish “have the most dramatic example of decoupling of the head and the trunk regions that we are aware of today,” said Formery.

Studying groups like echinoderms could solve some of the most complex mysteries about the evolution of life on Earth. “People are generally not drawn to these animals, and yet they probably represent how much of life got started,” Lowe said. Understanding how animals like starfish have developed could also allow insights into the varied ways that different species remain healthy. Daniel Rokhsar at the University of California said, “If we explore unusual animals that are operating in unusual ways, that means we are broadening our perspective of biology. This is eventually going to help us solve both ecological and biomedical problems.”

6 . It is very likely that you eat three meals a day. Modern life is designed around this way of eating. However, is this the healthiest way to eat? Before considering how frequently we should eat, scientists urge us to consider when we shouldn’t.

Intermittent fasting (间歇性断食), where you restrict your food intake to an eight-hour window, has become a popular area of research. “It allows our digestive system to rest,” says Emily Manoogian at the Salk Institute for Biological Studies. Rozalyn Anderson at the University of Wisconsin explains, “Fasting puts the body in a different state, where it’s more ready to clear misfolded proteins.” Misfolded proteins are faulty versions of ordinary proteins, which have been associated with a number of diseases.

But if intermittent fasting is a healthy way to eat, how many meals does this leave room for? Some experts argue that it is best to have one meal a day. Manoogian does not recommend doing this, since it can increase the level of glucose (葡萄糖) in our blood when we are not eating. Keeping blood glucose levels down requires eating more regularly than once a day, as this prevents the body from thinking that it is starving and releasing more glucose when you do eventually eat in response. Instead, she says, two to three meals a day is best — with most of your calories consumed earlier in the day.“ So, your body can use the energy you feed it throughout the day, rather than it being stored in your system as fat.” But eating too early in the morning should be avoided, as this would not give you sufficient time to fast. This does not mean we should skip breakfast altogether, either, but some evidence suggests we should wait an hour or two after waking up before cracking open the eggs.

Is intermittent fasting realistic? Manoogian thinks that it is best not to specify the best time to eat, as this can be difficult for people with responsibilities and irregular time commitments, such as those working night shifts. But whatever changes you make, researchers agree that consistency is crucial.

7 . Raised in Jacksonville, a small town in North Carolina, Christina Koch always knew she wanted to be an astronaut. This dream began as early as kindergarten, during a time when spaceflight was dominated by men. “Fortunately, when I told my kindergarten teachers that I wanted to be an astronaut they supported me. No one told me that it was unattainable. And whether it was my own hard-headedness or that encouragement, I did go full forward into pursuing my dream to become an astronaut,” she says.

Koch found inspiration in pioneers like Sally Ride and Mae Jemison, but also in everyday heroes — from civil rights activists to her independent grandmother. These examples, along with her family’s emphasis on hard work, instilled in her the courage to chase her dreams.

Koch studied physics and electrical engineering before joining NASA at the Goddard Space Flight Center, where she contributed to the development of scientific instruments on several space missions. Driven by a thirst for adventure, she spent a year in Antarctica’s tough environment and then in other remote locations like Greenland. Unsurprisingly, she cited photography, travel, camping and climbing among her hobbies.

The ultimate fulfillment (实现) of her dream came in 2013, when she was selected as an astronaut, joining a groundbreaking class with an equal number of men and women. Previously, women comprised only 17% of NASA’s astronauts. After completing training in 2015, she was assigned her first long-stay mission on the International Space Station (ISS). Her success is undeniable. As part of the Artemis II mission, scheduled for 2025, she’ll travel further than any human since Apollo, an evidence of her constant ambition.

Koch advocates following passions and embracing challenges. “Do what scares you,” she advises, “because those things often lead to the greatest fulfillment and contributions.”Besides, Koch also says that there’s one that should never be forgotten: “Support the people around you. Make sure that you’re thinking about the success of those around you, that you’re helping them, and together we all will achieve as much as we possibly can.”

1. What initially motivated Koch to become an astronaut?

A．Her desire to push herself to the limit.

B．Her early enthusiasm in space exploration.

C．Her wish to reward her kindergarten teachers.

D．Her ambition to change the position of women astronauts.

2. What can we infer from the passage?

A．Koch invented some scientific devices.

B．Koch set a record for the longest spaceflight.

C．Various hobbies prepared Koch for adventure.

D．Role models impacted Koch greatly in her life journey.

3. What does Koch’s advice indicate?

A．Seeking support is crucial for dream chasers.

B．Being kind to others is the stepstone to success.

C．Welcoming challenges leads to personal growth.
