17、Imagine walking through someone's house. The rooms are barren. There are no knickknacks (小摆设) lying around — just the essentials. You open the closet to find you can count the number of clothing items inside on one hand. The space seems more like a jail cell than a home.

It turns out that the house's owner is not poor. Instead, he is an extreme minimalist (极简主义者) who chooses to limit his number of belongings. Minimalists follow this philosophy to varying degrees, but they generally claim that cutting down on excess stuff leads to a more fulfilling life. With fewer possessions, they don't have to spend much time cleaning, thinking about what they are missing, or trying to keep up with the latest trends. They can then dive into hobbies that ignite their passion like exercising, traveling, and being with loved ones.

Extreme minimalism isn't for everyone, but a mild form of it has grown in popularity recently, thanks to Marie Kondo's best-selling book The Life-changing Magic of Tidying Up. Her philosophy of keeping only items that "spark joy" has resonated with millions, encouraging people to declutter their homes and minds. This shift toward intentional living reflects a broader desire to simplify daily life, moving away from excess and toward greater focus on what truly matters. They discover that fewer possessions often mean less stress and more clarity.

Kondo stresses that minimalism is not merely about throwing things away or holding onto what you want to keep. Even if you are not ready to become a minimalist, you may want to consider reducing the number of things you own, for it seems that letting go of things can truly make room for happiness.

A. This frees up their time for things that they find meaningful.

B. Such a balance helps people avoid the trap of mindless consumption.

C. No warmth, no life traces — just a cold, empty structure, not a home.

D. Even those who don't embrace full minimalism find value in scaling down.

E. Instead, it's about striking a balance between personal joy and possessions.

F. Minimalism goes against consumerism by dramatically scaling down possessions.

G. So you wonder whether the resident is too poor to buy more things to fill the house.

18、Have you ever stared at Vincent van Gogh's iconic painting The Starry Night and felt like you could almost see the sky moving? Well, it turns out that your eyes weren't playing tricks on you. A team of researchers has discovered that the swirling (旋动) patterns in van Gogh's masterpiece actually mirror real-world atmospheric turbulence (湍流) with surprising accuracy!

The researchers used some clever techniques to analyze van Gogh's brushstrokes. They treated the varying brightness of the paint colors as a stand-in for the energy of physical movement in the atmosphere. What they found was astonishing. The patterns in The Starry Night correspond to two important principles in fluid dynamics: Kolmogorov's law and Batchelor's scaling. Don't worry if these terms sound abstruse — let's break them down.

Kolmogorov's law describes how energy moves from larger to smaller scales in turbulent flows. Imagine a big swirl breaking down into smaller and smaller ones. This is what happens in the atmosphere, oceans… and amazingly, it's what van Gogh's work seems to represent. Batchelor's scaling, on the other hand, deals with how small-scale turbulence behaves. The researchers found that the fine details in van Gogh's brushstrokes match this principle, which describes how substances like heat or pollutants spread in a turbulent fluid.

Finding both of these patterns in one system is rare, which makes this discovery even more exciting. "It reveals a deep and intuitive understanding of natural phenomena. Van Gogh's precise representation of turbulence might be from studying the movement of clouds and the atmosphere or an inborn sense of how to capture the dynamism of the sky," says Yongxiang Huang, the study's lead author. The fact that an artist in the 19th century could capture these complex dynamics so accurately is mind-blowing. This research opens up exciting possibilities for the intersection of art and science. It shows that beauty and scientific accuracy aren't mutually exclusive — they might be more closely linked than we realize.

So, the next time you look at The Starry Night, remember that you're not just seeing a beautiful painting. You're witnessing a snapshot of the swirling, turbulent dance of the atmosphere.

19、Everybody's skin wrinkles with age, but the actual science behind why it happens is more complex than you may expect. Experts typically cite factors such as genetics, UV damage, and underlying pathological conditions. However, most evidence for skin wrinkling theories comes from studies that used computational modeling to estimate how the dermal layer (真皮层) changes over time.   Very few experiments involve testing theories with actual skin samples. With this in mind, researchers at Binghamton University, State University of NewYork decided to change that.

To gain a better understanding of skin's properties, Guy German and his colleagues hired a group of volunteers ranging in age between 16 and 91. They then used a low-force device to stretch small tissue samples of their skin to simulate everyday forces applied to the body's largest organ. The results clearly showed that as skin stretches one way, it also contracts (收缩) in the other direction. These contractions grow larger with age, forming wrinkles in the process.

German compared the dynamics to a popular, flexible children's toy. "If you stretch SillyPutty, for instance, it stretches horizontally, but it also shrinks in the other direction — it gets thinner. That's what skin does as well," he said. "As you get older, that contraction gets bigger. And if your skin is contracted too much, it folds. That's how wrinkles form." There is a bit more to it than just Silly Putty. According to German, your skin's mechanical properties get somewhat "unstable" as you age and "things degrade a bit".

So people with more physically active careers such as construction workers are likely to have more aged, wrinkled skin than office employees. But German stressed although different careers may lead to different skin conditions, taking proper skin-care measures is crucial for everyone.

While mechanical stress may be the biggest influence on how wrinkles initially develop, protection against major issues like sun damage and hormonal (激素的) imbalances will keep your skin healthy. Even if your skin is smooth, it doesn't mean it is immune to UV radiation. So be sure to continue applying suncream to yourself. Wrinkled or not, your body will be better off for it.

20、A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations (语调) of the driver's accent washed over me in a familiar way.

I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted at me in the rearview window (后视镜), and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up — the product of his sacrifice.

And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment, "All that work to get into Harvard, and you study history?"

Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) — to make money and send money back home. The unspoken demand, made across generations which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative of upward mobility so your children can do the same.

I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't huff and get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.
