阅读理解

    The ocean is filled with eight million tons of rubbish—enough to fill five carrier bags for every foot of coastline on the planet. But a new invention could deal with this problem, one port at a time.

    A pair of surfers from Perth, Australia, has invented a "floating bin" that automatically draws rubbish floating on the water into it like a vacuum (真空) cleaner. While the invention may do little to battle against five giant "garbage islands" that flow around the world's  major ocean gyres (环流), it could stop waste from leaving harbours and marinas, for example. Peter Ceglinski and Andrew Turton said their device could spell the end of polluted seas.

    The concept is simple: A bucket connects to a water pump, drawing in any floating trash inside a removable net bag. There is also an optional oil-water separator system inside the pump. It can remove oil from the seawater before spitting it back into the ocean — pollution-free — through the other side of the pump.

    The water filtration (过滤) system is much like what you'd find in a fish tank, but it has the potential to clean up an entire ocean. The seabin can run 24/7, according to its website. And, amazingly, Peter and Andrew say they have never caught a fish or sea animal in their pumps in four years of testing.

    The Seabin Project aims to improve on the traditional and sometimes expensive — harbor cleaning methods of having a person physically remove trash from the water or sending boats equipped with nets to collect it. While it's not as extensive as 21-year-old Boyan Slat's plan to clean the entire Pacific Ocean in 10 years, starting in 2020, the seabin's creators said their device is something that harbors can start using to clean our oceans now.

    They're starting "close to the source of the problem in a controlled environment," Seabin's website states. "It's a big mission, but it can be done. In fact, we're doing it right now."

(1)、What led to the two surfers' invention?
A、Poor equipment of boats. B、Great interest in surfing. C、Disturbing ocean rubbish D、Lack of harbor cleaning methods.
(2)、What does the underlined word "spell" in Paragraph 2 probably mean?
A、Indicate B、Change. C、Meet. D、Reach.
(3)、What is a seabin according to the text?
A、A fish tank. B、A vacuum cleaner. C、A water filtration system. D、A floating rubbish collector.
(4)、What can be inferred from the last paragraph?
A、The seabin is applied worldwide. B、It is challenging for the seabin to clean polluted seas. C、The seabin is far from satisfactory. D、It is possible for the seabin to control the environment.

    Long Beach, a 28-mile area of beach, lies in southwestern Washington, and is generally called Long Beach Peninsula. Communities there take you back to old days of a simple life. Here, visitors can relax and enjoy the good of a total rest.

    Bird watching

    There are different kinds of birds on Long Beach. It's best if you watch them from a distance and don't try to frighten them. The Southwest Loop Route Map can be got through the Long Beach Peninsula Visitors Office by calling 1-800-451-2542.

    Horses

    A popular activity on Long Beach is horseback riding. Two businesses in the city of Long Beach offer guided horseback tours along the beach: Black Country Wilderness Outfitters and Skipper's Equestrian Center. You may also bring your own horse. Among the adventures offered with horses is a wagon(四轮马车)ride along the beach, a carriage ride through Seaview or Long Beach, a back country pack trip, or a sunset ride by horseback on the beach.

    Camping

    RV(活动房屋式旅游车)and tent camping aren't allowed on the beach. Camp fires are allowed within 100 feet off the beach, but must be away from the dry grass.

    Swimming and other activities

    Swimming is allowed, but you must be careful. The waters are very cold and dangerous. Surfing(冲浪)is advised only for experienced surfers. Beach driving is allowed at certain areas on the beach. The speed limit is 25 mph. Building sand castles, digging sand to find something, riding bicycles and flying kites are also popular activities in the area.

    Enjoy your trip to Long Beach, Washington!

    Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time—about eight hours after you wake up—your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.

    In many parts of the world, people take naps(小憩) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap—even ten minutes of sleep can be helpful.

    E-Sports, short for electronic sports, is one of the growing industries in the world, with prizes totaling around $25 million up for grabs in some tournaments. E-Sports are professional multiplayer video game competitions. Any video game with a strong competitive element is considered e-Sports. The competition models itself after traditional professional sports in several ways: it uses corresponding tournament formats, involves player contracts, and is governed by regulations. The athletes who compete in e-Sports competitions are gamers.

    The history of e-Sports dates back to 1972 when some Stanford University students competed in the Intergalactic Space War Olympics for the opportunity to win a one-year subscription to the Rolling Stone Magazine. E-Sports pretty much continued on the rather quiet path until the 80s when competitions like the Space Invaders Championship shot them to the spotlight. 2002 marked the beginning of a new era for the sport and laid the foundation for what e-Sports would become thanks to the release of the Xbox live, which brought online play to consoles. Halo Ⅱ became the first game to be shown on national television for Major League Gaming in 2004, paving the way for e-Sports to become a global phenomenon.

    Today, e-Sports are growing at a rapid pace thanks to advance in technology and the arrival of streaming services like Twitch which have exposed video game competitions to a new audience due to their extensive reach.

    To understand how much impact Twitch has made, data from gaming analyst group Newzoo show that e-Sports global audience increased 43 percent from 204 million to 292 million between 2014 and 2016. Interestingly, this coincides (一致) with Amazon's acquisition of Twitch in 2014 and its effort to make the competition a spectator sport.

    An online supermarket company—Ocado in the UK, has recently displayed a robotic hand that can pick fruits and vegetables!

    When an embryo (胚胎) is in the womb, the very first sense it develops is touch. The sense of touch is also the one that lasts the longest—as we get older and our vision and hearing begins to weaken, touch still remains. Humans use their touch to protect themselves, to create emotional relationships with other people, and to experience pleasure. Can you imagine life without it?

    The sense of touch comes from a network of nerve endings and special touch receptors on the surface of the skin. While there are different kinds of touch receptors (感受器), they help us judge pressure, texture and vibrations (震动). They are located in our fingertips, palms, soles of our feet, face, lips and tongue.

    When we touch something, the mechano-receptors perceive the touch and through a network of nerves, send signals to the brain. This informs the brain about the location of the touch, the amount of force used, and the speed at which it was used.

    Several different techniques have been tried in the past to create such a robotic hand—using three fingers. But this latest design by SoMa copies the human hand. The gripper (夹具) is made up of flexible materials which grasp onto the thing based on its size and shape. Then air pressure is used to control the movement of the robotic fingers to pick objects safely and without causing damage.

    The next step would be for the robot to judge how ripe the fruits and vegetables are, and apply pressure accordingly. Members of the research team are currently working on adding computerized vision to the robots, so that they can see what they are gripping.

    Does all this mean robots can replace people? According to Ocado, it helps improve productivity by removing some of the repetitive tasks done by humans.

    Doing business nowadays without a cellphone? Living a very private life? I can't imagine it anymore.

    Journalist Chris Stokel-Walker explained it very well: For the average working person, there's no greater feeling than powering down your computer and kissing goodbye to your work emails for the day. If we're lucky enough to disconnect from the job on evenings and weekends, we're overjoyed to leave work emails and the stress that comes with it in the office.

    But experts say we're increasingly failing to do so, instead bringing the burden home with us and dealing with emails during our free time. Unsurprisingly, this routine has some serious consequences.

    Working abnormal or long hours has long been linked with depression(抑郁症), anxiety and even heart disease. In addition, the importance of weekend recovery has also been linked with weekly job performance and personal initiative(主动性). And further research showed psychological detachment(脱离) during off-work time reduced emotional exhaustion caused by high job demands and helped people stay engaged.

    So, if we know all this, it begs the question: Why are we still letting work bother our precious weekend? According to Cary Cooper, professor of Organizational School, the recent trend even spills into the way we access our work communications and projects.

    Today, says Cooper, work emails are just a tap of a smartphone away. "You don't carry your laptop around when you're out to dinner, but you do carry your mobile phone," he says. "The smartphone does not make up for what is lost." So delete your work email account from your inbox(收件箱), and leave the worries until Monday.
