According to body language expert Robert Phipps, the way people sleep at night actually determines a lot about the type of personality they have. Phipps has identified four sleeping positions that affect personality.

    Phipps found that worriers, those who stress the most, tend to sleep in the fetal (胎儿的) position. He found that this is the most common bedtime position, with nearly 58 percent of people sleeping on their side with knees up and head down. The more we curl up (蜷曲), the more comfort we are seeking, according to Phipps.

    The second most common position is the log. Sleeping with a straight body, with arms at each side, as if they are standing guard at Buckingham Palace, indicates stubbornness, and these people (the 28 percent who sleep this way) often wake up stiffer than when they went to sleep.

    “The longer you sleep like this, the more rigid your thinking is and you can become inflexible, which means you make things harder for yourself,” according to Phipps.

    Yearner (向往) sleepers are next on the list. About 25 percent of people sleep in this style—on their side with arms stretched out in front, looking as if they are either chasing a dream or perhaps being chased themselves. Yearners are typically their own worst critics, always expecting the best results, explained Phipps. These people often wake up refreshed and eager to face the challenges of the day ahead.

    Perhaps the most peculiar (奇怪的) of sleep styles is the freefaller position. This sleep style makes up 17 percent of the population. They sleep face down with arms stretched out. These people, according to Phipps, feel like they have little control over their life. Not only is this the strangest of sleep styles, but also the least comfortable, and people may wake up feeling tired and have no energy.

    Inconclusion, Phipps has only one more thing to add: “A good night's sleep set you up for the following day and our sleeping positions can determine how we feel when we wake.”

    Doctors in hospital emergency rooms often see accidental poisonings. A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning.

    In cases like this, seek medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.

    Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts(腹部按压), which you can do by getting directly behind a sitting or standing person. Put your arms around the victim's waist. Close one hand to form a ball. Place it over the upper part of the stomach, below the ribs. Place the other hand on top. Then push forcefully inward and upward. Repeat the abdominal thrusts until the object is expelled from the mouth. For someone who is pregnant or very fat, place your hands a little higher than with normal abdominal thrusts.

    Red Cross experts say taking these steps can save many lives. But they also warn that abdominal thrusts are not for people who have almost drowned. They say use of the method could delay other ways to re-start breathing in the victim. Abdominal thrusts should be used only in cases where a near-drowning victim is choking on an object.

    To learn more about first aid, ask a hospital or organization like a Red Cross or Red Crescent Society for information. There may be training classes offered in your area.

The situation is that familiar — deadlines are approaching, time runs out, disorder and confusion fills the day. The feeling is just as familiar — a slightly faster heart rate, and shortness of breath. Yes, it is panic time.

    It's too late to kick yourself with "I should have started on this sooner." or "It was a mistake to accept this tight deadline." The only thing left to deal with the situation is to panic more efficiently.

    ① Focus.

Panic happens when you are on an overload — too many things to do, too much pressure, too little time. But if you focus on the tasks that you need to take care of, and line them up in a logical list, you can have better control of a highly stressful and wild situation.

    ② Get rid of distractions.

    Time wasters and unnecessary activities are the last things you need during this time. Let everyone know you are on panic mode and should not be disturbed unless it is an emergency.

    ③ Watch your time.

    Don't be too engaged in one detail so that you reduce your timing for the other important details. Mind the time and deal with each task so that you can finish all of the required activities sufficiently.

    Try to solve a panic situation as quickly as you can so that you can rest and get back your energy and strength for the next one.

    For centuries, dolphins have got our admiration, and it is easy to see why. They are beautiful, cute and smart sea animals. Dolphins are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way, they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. It is said that dolphins are the world's second brightest creatures after humans and have many brain features related to intelligence. Their brain is nearly the same size as our own, and they live a long time at least twenty or thirty years.

    Like some animals, dolphins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.

    Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.

    There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area－except for The Penguin.

    Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

    Two deer jumped out in front of 16-year-old Amanda Floyd's car. She stepped on the brake, stopping the car just in time. But later, she started texting. Distracted (分心的)，Amanda turned left and right, then crashed into another car. Luckily, she wasn't in a real car--she was in a driving simulator (模拟器) at Roosevelt High School, Ohio, US. “I never really realized that cars make a turn that much," Amanda, a Junior, said. She added that she wouldn't text while driving anymore.

    The Ohio Department of Transportation (ODOT) and State Highway Patrol brought the simulator to the school. They said they wanted to help students learn about the danger of driving while drunk, while texting, or while talking on the phone.

According to the National Highway Traffic Safety Administration, distracted driving claimed 3,4501ives in2016 alone. Experts believe the actual figure is probably higher.

The simulator is basically a computer program. Like many computer games, it was a hit with the students. They lined up and crowded around to watch each other take turns. The simulator has a steering wheel! (方向盘) ,brake and gas pedal (油门踏板) . It is made up of three large computer screens on a table.

    Students choose a distraction, such as driving while drunk or texting. They always crash, of course. Then, they are pulled over by the police to be taught the bad results of their driving: how much damage they've caused, what their fine is, if anyone died in the accident, and if they're going to go to prison.

    "It teaches how to drive without being on the road," said Shante Thompson, 16. She had just crashed into a deer.

    ODOT spokesman Justin Chesnic said hundreds of kids have gone behind the wheel so far. He said even more have benefited from watching their classmates. "Driving is such a major responsibility, so take it seriously" he said. “Put away your cellphone. A lot of the accidents out there are because of distracted driving. It can not only change your life, but it can change someone else's life forever. The results are serious."

Scholars in quest of demystifying the enigmatic depths of the subaquatic cosmos have been bestowed with a trove of invaluable data, courtesy of a conglomerate of international experts who have compiled a compendium delineating the fauna that emit or are anticipated to emit acoustic waves beneath the waterline.

Under the aegis of Audrey Looby, a luminary from the University of Florida, the Global Library of Underwater Biological Sounds consortium, in unison with the World Register of Marine Species, has meticulously chronicled 729 species of marine mammals, aquatic vertebrates, and invertebrates that generate either active or passive auditory signals. Furthermore, the register encompasses an additional 21,911 species presumed to be potential sources of sound.

"Given that the aquatic expanse envelops more than 70% of the Earth's terrestrial envelope, the majority of our planet's ecosystems are submerged, and it is a prevalent misconception that the majority of these aquatic entities exist in an auditory vacuum. The recently unveiled exhaustive digital repository, which catalogues the known sound-producing creatures, is unprecedented and has the potential to transform the domains of marine and aquatic science," elucidated the team of investigators.

"The act of eavesdropping on the subaquatic symphony can unveil a plethora of insights regarding the species that orchestrate these sounds and serves a multitude of applications, from the stewardship of fisheries, the detection of invasive species, to the appraisal of the imprint of human activity on the environment," remarked Looby, who is also the co-architect of FishSounds, a repository that curates a spectrum of research records on the acoustic emissions of fish.

The research of this collective was disseminated in the annals of Scientific Data and featured contributions from 19 scribes hailing from six distinct nations. "Comprehending the modalities of interaction between marine species and their environs is of paramount global significance, and the unrestricted availability of this dataset marks a monumental stride towards this aspiration," proclaimed Keran Cox, an affiliate of the investigative cadre.

"The majority of individuals are acquainted with the vocalizations of cetaceans or marine mammals, yet are frequently astonished to discover that a multitude of fish and invertebrates also utilize sound as a medium of communication," Looby stated. "Our database serves to exemplify the ubiquity of sound production in the subaquatic realm across a diverse array of creatures, yet our understanding remains in its infancy, with much yet to be uncovered."
