    "Excuse me," he waved to the waiter. The waiter arrived at our table. "I1cottage cheese, but this is the mushroom." The waiter returned with a(n) 2smile on his face and said, "I'm sorry sir. I3took the order for the mushroom." "Then change it immediately," I said angrily. I had4my professor, who had retired as CEO of a billion-dollar multinational corporation, to lunch at the 5 restaurant. The waiter smiled awkwardly. I 6 to begin the "do-you-know-who-he-is" dialogue. But my professor was quicker. He said, "It's alright. Just don't7 me for both dishes," and laughed. "No, sir. Sorry, sir. Thank you, sir,” the waiter said and the8and gratefulness were written all over his face.

    "Why did you do that, sir?" I asked, 9. "It's his duty to change your dish," I said. "See how crowded the restaurant is? It's a(n) 10 noon. Vernon," my professor said. "Changing my order would mean more11for him and the chef. Maybe the waiter is 12. He probably would get a warning from the manager for this 13. Why put them through all this 14? This mushroom isn't bad."

    When the bill arrived, my professor 15 paying it. He even left a big tip. When we walked out, he smiled at the waiter, who 16 so low that I thought he'd break his back. My professor also smiled and17 the doorman when he thanked us for visiting.

    Here was my professor, Mr. Smith, being sympathetic to people below his18, and treating them like friends. "The true measure of a man is19he treats someone who can do him absolutely no good," said Samuel Johnson. I'll follow my professor's20and try my best to do the same.

    It is often said that "a picture is worth a thousand words." That is certainly true of the images of fleeting moments of nature submitted by international ecologists and students for the British Ecological Society's (BES) annual photography competition. Here are a few of 2019's winning entries.

    Red Night

    Photographed by Roberto Garcia Roa, it was declared last year's overall winner. The image captures both the beauty of the magnificent snake and its fear of human threats like fires. The ecologist says, "During my visit to Madagascar, I had the pleasure of finding this snake and photographing it. To offer a dramatic scene reflecting the conditions that these snakes are suffering, I used an external red light as a source of light to capture the environment."

    The Rhino's Annual Haircut

    It was photographed by ecologist Molly Penny. The ongoing demand for rhino (犀牛) horns has reduced the population to just 30,000 globally. To try to save the species, ecologists in South Africa, home to over 20,000 southern white rhinos, have decided to saw off (锯掉) it part of the animals' horns, which regrow every year. "The Rhino's Annual Haircut," captured beautifully in the black-and-white photo by Molly Penny from the University of the West of England, reduces the risk of the animals being cruelly murdered.

    For the Love of Flamingos

    Photographed by Peter Hudson, it captures a heart-shaped cloud of pink flamingos in Kenya, which is truly a sight like none other. The ecologist says, "Flamingos are all legs and necks but meanwhile beautiful and fascinating and I admit I have a deep passion for them, so I was thrilled when, flying high over Lake Magadi, I watched this flock from themselves into a heart shape."

    Flames in Flumes

    Photographed by Nilanjan Chatterjee, it captures a water redstart waiting to catch an insect near a small waterfall. It was the best overall student submission. The photographer wanted to show the struggle the river birds are likely to face from the slowdown in water flow due to planned dams in rivers across India.

    Like many other students beginning graduate school, I was quickly charged with responsibilities and had to find time for studying by letting goof many other things I valued. Letting go of football and the violin was, however, self-defeating: it might have brought me more time in the short term, but spending that extra time on work only' made me more stressed and less productive.

    Towards the end of the MSC (Master of Science program) started to lose my motivation and curiosity for science and research, as well as my creativity. Spending so much time and energy in the laboratory, and focusing all my attention on my thesis and courses, made me feel down and almost totally uninterested in my field - not to mention short-tempered and oversensitive in my personal communications.

    Over time, I learnt from these experiences. When I started my PhD, I focused on balancing academic success with personal time-off, and made personal happiness a priority (首要事情) in my weekly schedule. My mentor (导师) and I discussed my work-life balance early in my program, and we arrange our lab responsibilities accordingly.

    I set boundaries for myself in new ways: 'rather than doing lab work all weekend, I'd play football or the violin, or visit loved ones, before allowing myself to work fora few hours.

    This was hard at first: I worried that it would affect my standing with my peers, and superiors, but I had learnt from experiences that an overloaded schedule can drain (使疲劳) you so much that you become unfocused and start making mistakes or forgetting important details.

    Since establishing a better work-life balance, I've been doing well in graduate school. Outside the lab, I've been able to take up a few leadership positions at my university because I'm not as stressed with my work. I serve as our department's student councilor and I am also vice-president academic in the Health Sciences Graduate Students' Association. My advice is this: a healthy work-life balance isn't a luxury; it's a key part of success in graduate programs.

    Purdue University researchers have engineered flying robots that behave like hummingbirds, trained by machine learning algorithms (计算程序) based on various techniques the bird uses naturally every day. The robot would be able to fly better through collapsed buildings to find trapped victims.

    Even though such a robot can't see yet, it senses by touching surfaces. Each touch changes an electric current, which the researchers realized that they could track. Xinyan Deng, a professor, and her colleagues at Purdue have been trying to decode (破译) hummingbird flight so that robots can fly where larger aircraft can't. Deng's group studied hummingbirds themselves for many summers in Montana. They documented key hummingbird actions, such as making a rapid 180-degree turn, and translated them to computer algorithms that the robot could learn from when connected with a simulation (模拟操作).

    Further study on the physics of insects and hummingbirds allowed Purdue researchers to build robots smaller than hummingbirds--and even as small as insects-without compromising the way they fly. The smaller the size, the greater the wing flapping frequency, and the more efficiently they fly. The robots have 3D-printed bodies and wings made of carbon fiber. The researchers have built one hummingbird robot weighing 12 grams--the weight of the average adult hummingbird. The hummingbird robot can lift up to 27 grams.

    Designing their robots with higher lift gives the researchers more room to eventually add a battery and sensing technology, such as a-camera or GPS. Currently, the robot needs to be tied to an energy source while it flies-but that won't be for much longer, the researchers say. The robots could fly silently just as a real hummingbird does, making them more ideal for covert (转换) operations.

    Robotic hummingbirds would not only help with search-and-rescue tasks, but also allow biologists to more reliably study hummingbirds. In their natural environment through the senses of a realistic robot. This work is part of Purdue's 1501° anniversary. This is one of the four themes of the celebration's Ideas Festival, designed to show Purdue as an intellectual center solving real-world issues.

    We all have our bad days. No one is going to wake up each and every morning in a cheery mood. Sometimes we all feel just a little bit grumpier (脾气暴躁的) than usual, and that's just a part of being human. Yet once we get to the office, many in the workforce feel it necessary to hide their emotions, whether they are in frustration, anger, or sadness. Interestingly, a new study finds keeping one's behavior at the office authentic will result in greater productivity and a better relationship with co-workers. In other words: act how you feel, and don't fake it.

    It's extremely common for the average workspace to preach an attitude of continuous positivity. While this may be beneficial from the CEO's viewpoint, it just isn't realistic when applied to real people with real problems and daily hardships. That's why, the research team have concluded, employees will actually feel better, work harder, and connect more with their colleagues if they don't hide their feelings with a fake smile.

    Over 2,500 working adults, from a variety of industries such as finance or engineering, took part in this research via surveys. The questionnaires measured two distinct types of on-the-job emotional regulation: surface acting and deep acting. Surface acting means faking happiness while interacting with other employees; and deep acting refers to actively trying to change one's emotions and feelings in order to be more pleasant at work. The study's authors were interested to see how common it is for working adults to regulate their emotions while on the clock, and if so. Why? What benefits are employees gaining from such behavior?

    After analyzing all of the survey responses, researchers identified four distinct types of individuals who hide or regulate their emotions around co-workers. "Non-actors" rarely hide their true feelings, and if they do, only to a very small extent. "Low actors" usually take part in only slight deep and surface acting. "Deep actors" perform lots of deep acting and low levels of surface acting, and "Regulators" exhibit high levels of both surface and deep acting.

    By far non-actors were the smallest identified group in the study. Regulators, or employees who tend to hide their true feelings most often, are usually motivated by feelings of self-interest. These people believe that by hiding their feelings they will gain access to additional work resources and look good in front of their managers and co-workers. Deep actors, on the other hand, are usually more motivated by "pro-social" factors. This means they choose to hide their emotions because they believe it develops a healthier working environment. Regulators are the most likely of the four to experience great emotional tiredness and exhaustion. Meanwhile, deep actors tend to achieve improved well-being most frequently.

    David Carter stands outside of the University of Texas' Austin campus every day, offering the same warm greeting to students who pass by. "Hello, my friend!"

    Carter, now 68, is a beggar who once attended the school from 1972 to L975. Then, he was involved in a crash and got serious injuries. He then had trouble with substance abuse and faced mental health challenges, leading him to drop out before completing his degree.

    "If I could change one thing about my past life, I would have stayed in school," Carter says. He says he knows an education can change someone's quality of life.

    Carter had to beg in the last few years fora simple reason. "I'm always flat broke," he said. While most people would walk right by a beggar, Ryan Chandler, a junior at the university, decided to stop and chat with Carter-and he learned a valuable lesson: You can't judge a book by its cover.

    "A lot of UT students see them as criminal vagrants (无业游民,乞丐) or think that they are dangerous or unfriendly, and that idea just isn't true," says Chandler.

    Chandler got to know Carter and saw his potential. "He completed 87 hours of course credits, which is enough for a degree for most people, but he just never finished," Chandler says.

    The student wrote a blog post about his new friend, and luckily, the right people heard about Carter and stepped in to help. The University of Texas readmitted Carter as a student, and a kind person who used to be a student UT offered to pay for Carter's tuition.

    "I want to be a student and I want to learn," Carter said. Since the course requirements have changed, Carter is far from having the amount of credits needed to graduate. But his friend knows he's willing to take up the challenge. "He is capable, he is ready, and he is dedicated to this," Chandler says.
