Most people think that procrastination (拖延症) is a negative habit. But people like me who routinely put off doing assignments, are likely to defend our “slower” approach to getting tasks done.
I'm the only procrastination in my family. My parents and sister were all born with the “do it right now” gift. They are always in a rush, as if closely rushed by an invisible deadline. Personally, I prefer a more relaxed pace. When my parents voiced their concern about my tendencies, saying “Don’t put off until tomorrow what you can do today,” “No way!” I responded, confidently presenting my research as a defense. It said people procrastinated when they need to solve a problem or commit to a topic or project. In these cases, delaying a decision can be beneficial. This was because our minds continue to reflect on problems even when we were not actively thinking about them, which could lead to more creative solutions. My findings filled me with satisfaction and pride. My method of getting things done was just as good as my sister’s…or so I thought.
At school we’d been talking about architecture and design. As part of the final assessment my teacher Mr. Smith announced an exciting project that each student would have a month to complete. We were expected to choose our materials, construct a small building and make use of things we had learned in class. Not only would the winners receive extra credit, but the winning constructions would be proudly displayed in the cafeteria. “I have no clue how I could get it done,” my friend Nate sighed in despair. I didn’t say anything. Not because I shared his anxiety-but because I was not nervous at all. I loved hands-on projects! Picturing my brilliant work exhibited in the cafeteria, I was fully convinced that I would definitely produce something that could impress everyone. So relaxed was I that I didn’t give it a second thought for weeks.

Evolution (进化) can perform extraordinary makeovers; today’s airborne songbirds evolved from the wingless, earthbound dinosaurs that wandered millions of years ago. But some organisms seem to be unchanged — in other words, escape natural selection. The coelacanth, a modern-day fish, is nearly identical to its410-million-year-old fossils.
Scientists have long wondered how these species do so. It has been assumed that natural selection keeps some species unchanged by selecting for moderate or average qualities (stabilizing selection) rather than selecting for more extreme qualities that would cause a species to change (directional selection).
But a study published in the National Academy of Sciences USA contradicts this idea, showing that evolution constantly favors different qualities in seemingly unchanging animals to improve short-term survival. In the long term, though, “all that evolution cancels out and leads to no change,” says the study’s lead author, James Stroud.
Stroud and his colleagues studied for lizard (蜥蜴) specios; all relatively unchanged for 20 million years. The researchers caught members of these populations every six months for three years. They measured each lizard’s head size, leg length, mass and height, as well as the size of its sticky toes (脚趾头), noting which individuals survived. Stroud expected to observe stabılızıng selection at work preserving moderate qualities. Instead he saw clearer evidence of directional selection: some lizards with unique characteristics, such as stickier toes, survived better.
“The study offers a good explanation for why we see what we think is stabiliring selection,” says Tadashi Fukami, an ecologist studying evolution at Stanford University. Many new qualities are evolving in the short term, but they don’t provide a crucial advantage over the long term. In other words, species staying unchanged may simply have found the best possible combination of qualities for lasting success in their environment. So what happens when the lizards’ environment changes more dramatically? To help answer this bigger question, Stroud is still making trips to visit the lizards.

In New England, a few years ago, a party of boys decided to start a grand sleigh (雪橇) ride. The sleigh was a large one, pulled by six gray horses.
The next day, as the teacher entered the schoolroom, he found his students in high spirits, chattering excitedly about their journey. One of the boys recounted their trip and its various incidents. As he reached the end of his story, he exclaimed, “Oh sir, there was one thing I had almost forgotten. As we were coming home, we saw a strange sight on the road. It turned out to be a rust y old sleigh attached to a covered wagon (四轮运货车), moving at a very slow pace and taking up the entire road.”
The boys had grown impatient with the slow-moving vehicle ahead of them and decided to take action. They threw snowballs at the wagon and shouted, making the old horse start to run quickly. The old man in the wagon cried out, asking why they were frightening his horse. A boy replied, “Why don’t you turn out, then?” and gave him three more loud cheers. His horse was frightened again and ran into a loaded wagon, almost making the old man fall over.
The teacher listened carefully to the boy’s story before responding, “Take your seats, boys, and I will tell you a story about a sleigh ride, too.”
Yesterday afternoon, a very elderly man was traveling from Boston to Salem to spend the winter at his son’s house. He had brought his wagon for the journey and his sleigh for the winter. His vision and hearing were not what they used to be due to his age. He was traveling slowly, as his horse was old and weak like himself. Suddenly, he was frightened by loud cheers and rapid snowballs hitting his wagon. In his panic, he dropped the reins and his horse ran wildly. Amidst his troubles, a large group of boys in a sleigh pulled by six horses rushed past him, shouting and demanding that he give them the road.

I sat in the breakfast corner with my four-year-old son, Matthew, trying to ignore the ache in my stomach. I was still recovering from a surgery. I hoped for strength and happiness. But the future seemed so hopeless.
Matthew jumped up from his spot on the kitchen floor. “Bird!” he shouted, rushing to the sliding door. Sure enough, there was a white dove seated on a rubber tree. It sat there a few moments, and then flew away. I’d never seen one in our neighborhood before.
When I dragged myself to the kitchen the next morning, the dove was back. This time it was with a mate carrying twigs (嫩枝), “Look, Matthew,” I said, pointing to the tree. “They’re going to make a nest.” The doves flew in and out of the courtyard all week, building on the top of the rubber tree. Matthew could hardly contain his excitement. Every morning, he’d run into the kitchen and take his spot by the sliding glass door, talking to the birds while they worked. As much as I was grieving (感到悲伤), I couldn’t help but look forward to the doves’ visits too. We watched their progress as if it were a real-life soap opera unfolding before us. Gradually, my pain disappeared, replaced by joy.
Then it all went wrong. The courtyard was a safe enough spot for a nest, but the rubber tree’s broad, thin leaves were far from stable. One night, a strong wind blew through, throwing the doves’ nest to the ground. I heard the twigs break apart. Nothing good ever lasts. I wouldn’t blame the doves if they never came back. But they returned. And they paid no attention to the pi le of sticks that had once been their nest. They started again from scratch, though the wind destroyed all their hard work. The next day, and the next, they renewed their efforts, as if nothing had happened.

____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________I was always afraid of water. This fear could not be explained, but I knew that the moment I stepped near any body of water, my legs would turn to jelly (果冻). I would imagine myself drowning in the water and thrashing around (乱扑腾) helplessly. That was why I had never gone into a swimming pool until swimming became a school requirement. My school wanted all pupils to pass a swimming test, and if they could not, then they would have to attend weekly swimming lessons in school, which made me tremble.
Thus, my parents signed me up for swimming lessons at the pool near my house. With great unwillingness, I attended those weekly lessons, and each one was great suffering for me. I was naturally clumsy, and my fear of water did not help at all. Every lesson, I would be spending my time thrashing about in the water, while my classmates would be swimming countless laps effortlessly and even turning over like dolphins in the water. How was I going to pass the test at this rate?
In my swimming class, there was an exceptionally athletic girl. Tall and muscular, her name was Kathy. She was the best swimmer in our class and always looked at me with disdain (鄙视), especially when I thrashed about hopelessly in the water.
Once, after a particularly long and hard swimming lesson, I spotted Kathy swimming gracefully in the pool. Gathering my courage, I asked gently, “Kathy, can you teach me to swim?” She stared at me coldly. It was as if I stood at the edge of an endless ocean of inadequacy, my fears appearing like dark storm clouds threatening to drown me. Yet, in that moment, a glimmer of hope flashed within me, a desperate longing for guidance and acceptance. Would Kathy’s icy exterior (外表) melt under the warmth of empathy, or would I remain forever thrashing in the sea of my own fears?

9 . Do you see a bird right now? Can you hear one chirping? If so, you might be getting a mental health boost. A study recently published in the journal Science found that being in the presence of birds made people feel more positive.
Andrea Mechelli, a psychologist at King’s College London, found himself studying the natural world accidentally. Initially he was searching for answers to why people who lived in cities seemed to tend to suffer mental illness, particularly psychosis. In 2015, he created the smartphone app Urban Mind to search for patterns in users’ environments. “Our first finding is that nature has a very powerful effect,” says Mechelli. He and his colleagues then wondered if some aspects of nature were more beneficial than others. They turned to birds for their ubiquity (普遍存在) in rural and urban environments.
Their latest study included 1,292 participants mainly in the United Kingdom and Europe. For two weeks, participants were prompted to fill out a questionnaire about their surrounding environment and their mental state three times a day. Mechelli performed a statistical analysis that found an obvious improvement in wellbeing when birds were present, even when eliminating other factors like the presence of trees or waterways. The mental health benefit was true both for people who disclosed a depression diagnosis and those without any diagnosed mental health conditions.
Peter James, an environmental health scientist at Harvard, would like to see more data. He found that environmental health studies like these lack diversity. Yet, a psychologist at Trent University in Canada, Lisa Nisbet says, “This kind of study helps us understand how people’s everyday experience with specific elements of nature, such as birds, can be restorative.”
Appreciating birds seems to be a promising avenue for nature-based health and wellbeing interventions. At Mechelli’s clinical practice in London, he focuses on early intervention therapies. He suggests his patients go for walks to observe the trees and plants growing in the city, and the bird fluttering by from branch to branch. “It has no side effects,” he says. “It’s something they could try, and they have nothing to lose.”
