【正文】 gside the shore. However, inexperienced beachgoers often panic, and try to swim to land, placing themselves at risk of drowning due to tiredness. According to the US National Ocean Service, the currents kill about 100 Americans each year and account for 80% of all lifeguard rescues. These scary statistics may soon be a thing of the past, thanks to Clever Girl, a smart buoy (浮標) that warns swimmers of the presence of deadly rip currents.The smart device is the brainchild of Australian teenager Maddison King, who created Clever Girl as a project for her Grade 12 Design and Technology class. The 18yearold, who works as a lifeguard during her spare time, came up with the brilliant idea after discovering that most children were unable to detect rip currents.The basketballsized plastic buoy, which can be attached to a chain of similar devices or the ocean floor, is fitted with a small propeller (螺旋槳). When the water travels at speeds of over 70 centimeters per second, it spins the propeller fast enough to power the light atop the buoy, warning swimmers to stay clear of the area.Though it sounds simple enough, the youngster had to overe numerous design challenges. For instance, she picked a red light since it is easy to see in the bright sunlight and also because the color serves as a universal warning sign for tourists that do not speak the local language. The device’s smooth surface and high handles ensure swimmers do not get hurt, while the black, white, and red striped underside, keeps sharks and other animals at bay.Future versions might include something like a warning siren, which would provide sound warnings of rip currents. Besides, the present model cost about $ 300 to make. “That’s beyond my purse.” she laughs, “the cost has to be cut down.” 32. Which of the following is the right way to escape the rip current?A.
