语篇解读:

对于每一位海洋爱好者来说,被困于离岸流是很危险的。

本文主要介绍了当人们被这种海流困住时,应如何自救才能化险为夷,并介绍了澳大利亚女孩发明的离岸流警报装置CleverGirl。

答案及剖析:

1.D　细节理解题。

根据第一段第二句“...toescapethenarrowchannelofthefastmovingwaterbyfloatingandallowingittodragyoufurtherintotheoceanorbyswimmingalongsidetheshore.”可知,对于有经验的游泳者来说,相对容易地摆脱离岸流的方法是漂浮在水面顺流游动或者沿着海岸游动。

2.B　推理判断题。

根据文中第二段最后一句“The18-year-old,whoworksasalifeguardduringhersparetime,cameupwiththebrilliantideaafterdiscoveringthatmostchildrenwereunabletodetectripcurrents.”可知,这位18岁的女孩在她业余时间当救生员时,发现大多数孩子不能发现离岸流,所以她想到了这个主意。

3.A　推理判断题。

根据文中最后一段“Besides,thepresentmodelcostabout$300tomake.”可知,这种装置目前还只是模型（model）,这说明目前市场上还没有这种产品。

4.D　推理判断题。

根据文章最后一段第一句中的includesomethinglikeawarningsiren,whichwouldprovidesoundwarningsofripcurrents及最后一句中的“‘thecosthastobecutdown’”可知,这一装置将来会更高效,且目前制作成本较高,所以其成本还要降低。
