A mouse looked through a crack inthe wall to see the farmer and his wife opening a package: What food might itcontain? He was astonished to discover that it was a mouse trap!

    Retreating to the farmyard, the mouse declared the warning, “There is a mouse trap in the house, there is a mouse trap in thehouse.”

    The chicken clucked and scratched,raised her head and said, “Mr Mouse, I can tell you this is a grave concern to you, but it is of no consequence to me, I cannot be bothered by it.”

    The mouse turned to the pig and told him, “There is a mouse trap in the house.” “I am so sorry, Mr Mouse,”sympathized the pig, “but there is nothing I can do about it but pray; beassured that you are in my prayers.”

    The mouse turned to the cow, who replied, “A mouse trap, am I in grave danger, huh?”

    So the mouse returned to the house, head down and depressed to face the farmer's mouse trap alone.

    That very night a sound was heard throughout the house, like the sound of a mouse trap catching its prey. The farmer's wife rushed to see what was caught. In the darkness, she did not see that it was an evil snake whose tail the trap had caught. The snake bit the farmer's wife. The farmer rushed her to the hospital. She returned home with a fever. Now everyone knew to treat a fever with fresh chicken soup, so the farmer took his hatchet to the farmyard for the soup's main ingredient. His wife's sickness continued so that friends and neighbors came to sit with her around the clock. To feed them, the farmer but chered the pig. The farmer's wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow slaughtered to provide meat for all of them to eat.

    So the next time you hear that someone is facing a problem and think that it does not concern you, remember that when the least of us is threatened, we are all at risk.

    Summer is the season to dive into new activities and relax. And right now is the time to make sure that you're ready for the great outdoors, the holiday planning and travel, and the bathing suit beach days.

    If you want to lose weight before summer, concentrate on dropping no more than a pound or two a week.{#blank#}1{#/blank#} And when you trouble yourself, sooner or later you，re going to gain it back. Operate on a 500-calorie-a-day deficit (亏损).{#blank#}2{#/blank#} So if you cut 500 calories a day for seven days straight, you'll lose a pound a week right there.

    Operating at a decrease of 500 calories a day should involve both eating less and moving more. For example, you could consume 300 fewer calories and bum 200 extra per day.

    Include both healthy eating and exercise in your weight-loss plan, and break the 500-calorie goal into small groups to make it more reachable.{#blank#}3{#/blank#}

    To cut 100 calories:{#blank#}4{#/blank#} Have vegetable pizza instead of pepperoni (意大利辣香肠). Use our Nutritional Needs Calculator to determine how many daily calories you should consume in order to lose, gain, or maintain your healthy goal weight. Once you've reached your goal, recalculate your nutritional needs for keeping extra weight off all summer long.

    To burn 100 calories: spend 15 minutes biking. {#blank#}5{#/blank#} Spend 20 minutes gardening. Keep on exercising at least 30 minutes daily a week. Reading food labels and counting calories or writing down what and when you eat can give you more control as well.

A. Here are some simple ways to get there.

B. Walk or run one mile.

C. A pound is 3,500 calories.

D. It is okay to have some snacks between your meals.

E. You should always make sure you get a lot of sleep.

F. Anything more than that usually means you're troubling yourself.

G. Eat a chicken breast without the skin.

    Far out in the lake was a large wooden platform(平台) on which stood an improbably high diving board- a kind of wooden Eiffel Tower. It was, I'm sure, the county's tallest wooden structure (结构) and no one had ever been known to jump from it. So it was quite a shock when our teacher, Mr. Milton, announced that he would dive off the high board that very afternoon.

    Word of his questionable plan was already spreading through town as Mr. Milton swam out to the platform. He was just a tiny, stick figure when he got there but even from such a distance the high board seemed almost to touch the clouds. Once at the top, he paced the enormously long board , then look some deep breaths and finally stood at the edge. He was going to do it.

    Several hundred people had gathered at the shore to watch. Mr. Milton stood for quite along time ;then he raised his arms, took one bounce(弹跳) and launched himself into ;perfect dive. He fell with perfect style for what seemed minutes. The crowd fell silent. But about three quarters of the way down he seemed to have second thoughts and began suddenly to panic(惊慌)，waving his arms and legs like someone having a bad dream. When he was perhaps thirty feet above the water, he gave up on waving and spread his arms and legs wide, obviously hoping that it would somehow slow his fall. It didn't. He hit the water at over six hundred miles an hour, making birds fly out of their trees three miles away. I don't think he entered the water at all. He just bounced off it, about fifteen feet back into the air. After that, he lay still on the surface , like an autumn leaf.

    He was brought to shore by two passing fishermen in a rowboat and placed on an old blanket where he spent the rest of the afternoon. Occasionally he accepted a little water, but otherwise was too shocked to speak.

    It was the best day of my life.

    Seventy-three-year-old George McNeilon selected his food in Value Mart very carefully. After leaving the cashier, he estimated (估计) that he had saved 80 cents and thought that he had got good value for his money again.

    At the exit, the chilly wind reminded him of his gloves. "Now where are they?" He searched here and there, but nowhere could he find them. He was sure he was wearing them when he entered the store. The worried man made a second search in all his pockets, again including the grocery bag. He was sure they must have been dropped somewhere inside the store.

    George bought the gloves at a 25% discount, for just $30, ten years ago. They were genuine lambskin (小羊皮), soft, warm and durable. Until then, he had worn cheaper man-made material that lasted no more than three years. His impulsive decision to buy the expensive gloves turned out to be a good one, which even promoted his social status on the bus, as passengers stared at him enviously for six months out of the year. He enjoyed being envied.

    Bad luck, George thought, to lose his expensive gloves on New Year's Eve. He reentered the store and followed the same route he had walked before. But several minutes of anxious search turned out to be in vain. "Society has changed. People have changed …" he murmured to himself. "Years ago, if people picked up something lost, they would give it back."

    Back home, George was at a loss. In deep winter, he could not do anything without a pair of gloves. If he bought cheap ones, he would have to replace them very soon. If he bought new leather ones, they would cost forty dollars.

    After the holiday, poor George decided to buy another pair of leather gloves. Before boarding the subway, he stepped into Value Mart again to see if by any chance his gloves had been returned to the lost and found office.

    "What color are they?" the woman in the office asked.

    "Black," he answered.

    She looked into her drawer and drew out a pair of men's leather gloves.

    "Are they?"

    "Yes! Those are mine!"

    When you live in total messiness—cookies in your pants draws, and some old New Yorkers or apple seeds in your bed—it's hard to know where to look for when you lose your keys. The other day, after two weeks of searching, I found my keys in the refrigerator. I can't say I was surprised. But I was surprised when I was diagnosed with ADHD(多动症), when I was a junior at Yale.

    According to a new study, 11% of school-age children have received an ADHD diagnosis, a 16% increase since 2007. And rising diagnoses mean rising treatments—drugs like Adderall are more accessible than ever. However, the consequences of misuse and abuse of these drugs are dangerous.

    Yet also harmful are the consequences of ADHD undiagnosed, an all-too-common story for women like me, who have symptoms, like disorganization and forgetfulness, which look different from those typically expressed in males.

    Dr. Ellen, author of Understanding Girls with ADHD, has found around 4 million females with ADHD are not diagnosed. "The main reason is that the diagnostic criteria were developed based on those hyperactive（过度活跃）young boys taken to clinics, making it difficult for girls to be diagnosed unless they behave like hyperactive boys." Ellen says.

    Besides, the idea that young women actually have ADHD often causes skepticism. As a top student, I didn't believe my diagnosis at first. My friends were also confused, and rather certain my doctor was misguided.

    "Often, if girls are smart or in supportive homes, symptoms are masked," Dr.Ellen says. "Girls will hide their inability to meet social expectations. They see their trouble organizing, and concentrating as character flaws(缺陷)."

    These years, I am both embarrassed and exhausted by my struggles to keep track of objects, but drug has helped it and made it more bearable.

Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.

Researchers at the University of New South Wales, Australia, have invented a soft skin stretch device (SSD), a haptic device that can recreate the sense of touch. Haptic technology can mimic the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Vibration is the most common haptic technology today and has been built into many electronic devices, such as one attached to the back of a trackpad in laptops. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely.

The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through soft, artificial "muscles".

It works like this: imagine you call a friend in Australia. You wear a haptic glove with the SSDs and your friend also wears a glove with 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And the glove with 3D force sensors will measure these interactions. The force signals can be sent to your glove so your device will generate the same 3D forces, making you experience the same sense of touch as your friend.

The haptic devices could be used in various fields, allowing users to feel objects inside a virtual world or at a distance. This could be especially beneficial during such times like the COVID-19 pandemic when people rely on video calls to stay connected with loved ones. Or it could be used in medical practices. Doctors can feel a patient's organ tissues without touching them.
