    Hummingbirds(蜂鸟) are one of nature's most energetic fliers and the only birds to hover(盘旋) in the air by relying on their strength alone.

    Now scientists have found that it is the ratio(比值) of the bird's wing length to its width that makes them so efficient. The discovery is helping experts compete with 42 million years of natural selection to build helicopters that are increasingly efficient.

    David Lentink, an assistant professor at Stanford University in California, tested wings from 12 different species of hummingbirds, which he sourced from museums. He placed them on a machine used to test the aerodynamics(气力学) of the helicopter blades(桨叶). Professor Lentink's team used the same machine to test the blades from an advanced micro-helicopter used by the UK's army. They found that the micro-helicopter's blades are as efficient at hovering as the average hummingbirds.

    But while the micro-helicopter's blades kept pace with the average hummingbird wings, they could not keep up with the most efficient hummingbird's wing. The wings of Anna's hummingbird were found to be about 27 percent more efficient than the man-made micro- helicopter's blades.

    While Professor Lentink wasn't surprised at nature's superiority, he said that helicopter blades have come a long way. “The technology is at the level of an average hummingbird,” he said. “A helicopter is really the most efficient hovering device that we can build. The best hummingbirds are still better, but I think it's amazing that we're getting closer. It's not easy to match their performance, but if we build better wings with better shapes, we might match hummingbirds.”

    Professor Lentink said that we don't know how hummingbirds maintain their flight in a strong wind, how they navigate(确定方向) through branches, or how they change direction so quickly. He thinks that great steps could be made by studying wing aspect ratios-the ratio of wing length to wing width. Understanding these abilities and characteristics could be a benefit for robotics and will be the focus of future experiments.

    How could we possibly think that keeping animals in cages in unnatural environments ―mostly for entertainment purposes ―is fair and respectful?
    Zoo officials say they are concerned about animals. However, most zoos remain “collections” of interesting “things” rather than protective habitats. Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.
    Zoos claim to educate people and save endangered species, but visitors leave zoos without having learned anything meaningful about the animals' natural behaviour, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species' name, diet, and the natural range (分布区).The animals' normal behaviour is seldom noticed because zoos don't usually take care of the animals' natural needs.
    The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusual and self-destructive behaviour called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.
    Furthermore, most animals in zoos are not endangered. Captive breeding (圈养繁殖)of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programmes because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven't we seen enough competitions to name baby animals?
    Actually, we will save endangered species only if we save their habitats and put an end to the reasons why people kill them. Instead of supporting zoos, we should support groups that work to protect animals' natural habitats.

    On August 5 just after 7.30 pm, Mike Estepa suffered a massive heart attack. The crazy cyclist was 40 kilometres into his Sunday ride when he stopped by the side of the road to text his family saying he'd be home in about 30 minutes. Moments later, he was lying in the ditch, unconscious.

    Larissa Arthur was driving back to Calgary from a hike in Field, B. C. with a friend. It was a warm and sunny day, and the two were chatting when a flush of yellow caught Arthur's eyes. She immediately pulled off the road.

    As Arthur approached the figure, she feared the worst: Estepa was covered in ants and exhibited no signs of life. There was no pulse and he wasn't breathing." says Arthur. A bystander called 911 and Arthur, a registered nurse, started chest compressions. She and two other drivers took turns carrying out CPR for the next 15 minutes before medical teams arrived and whisked Estepa away.

    Two days later, when Estepa woke up in the hospital, he was shocked to learn he had gone into cardiac arrest (心脏骤停). How did this happen, and, why was he lucky enough to have survived? He was full of gratitude and needed to speak with the woman who had saved him, whom he named his "angel".

    "It was emotional," says Arthur of her meeting with Estepa a few weeks later. Saving his life had extra importance for her: the bike she was returning from that day was one of 100 she's planned to honour her father, who died in 2017 after he fell during a hike that Arthur was meant to be on. "I couldn't save my father's life." Arthur says, "but this was a chance for me to save someone."

I stood outside my front door catching my breath. After a lazy Christmas holiday, I had to recover from climbing stairs with carry-on bags and a suitcase. I looked up — Red tape crossed the door. I didn't understand French, but the one English word said enough, "POLICE". Google Translate told me I would be caught if I entered, so I didn't.

Finally, I called my rental agent (收租人). He went to the police station for more details. The thief had taken a few items from the top drawer as well as a small amount of money in the bottom drawer. Not only were my files undisturbed, but so were the TV and printer. My agent also said something about fixing the locks tomorrow and making a list for the police.

Then one day, I remembered that I had left another jewelry box in the flat. My heart sank as I thought of a gold locket (项链坠) with a picture of my late Grandma inside. When I realized the box was missing, the whole experience seemed to crash down on me. I cried. At the end of January, I received a letter from the police. The thief hadn't been found, and the case was closed. I slept with my purse by my bed. I hid my laptop when I showered. And then another challenge came — I was unexpectedly fired by my company.

One July night, I reached into my third drawer to pull out my jean shorts. I heard something fall to the ground. I looked down: It was the tiny jewelry box I thought had been stolen six months earlier. Inside was the locket with honey Grandma smiling at me, being there for me, telling me not to give up. I started to cry. I knew that things were going to be OK.
