2021高中英语北师大版必修3Unit 7
必修3Unit 7The Sea能力提升题组训练(A)Ⅰ.阅读Every ocean lover knows the dangers of getting caught in a rip current (离岸流).Experienced swimmers know it is relatively easy to escape the narrow channel of the fast moving water by floating and allowing it to drag you further into the ocean or by swimming alongside 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 (浮标) 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 18-year-old,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 basketball-sized plastic buoy,which can be attached to a chain of similar devices or the ocean floor,is fitted with a small propeller (螺旋桨).When the water travels at speed of over 70 centimeters per second,itspins 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 overcome 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 auniversal 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.”1.Which of the following is the right way to escape the rip current?A.Waiting for rescues.B.Swimming to the shore.C.Moving fast in the water.D.Floating with the water.2.Why did Maddison decide to invent Clever Girl?A.She wanted to challenge her creativity.B.She was motivated by her working experience.C.She was supposed to complete it for her class.D.She was scared by the statistics of the government.3.What do we know about the present version of Clever Girl?A.It’s not available on the market.B.It’s quite attractive for sea animals.C.It’s based on a complex theory.D.It can give warnings in different ways.4.What could the future version of Clever Girl be like?A.Safer and greener.B.Cheaper and safer.C.Greener and more effective.D.Cheaper and more effective.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。

Unit 7 The Sea
Far out in the sea there was an island, on the rocky edge of which lived three Sirens, the three sisters of magic song. Half- human and half- bird, the Siren sisters sat in a field of flowers, singing in voices that excited the hearts of men. The attractive songs were so sweet that ships were attracted to the island and struck to pieces on the rocks. No sailor nor ship had ever been known to pass the Island of the Sirens without being attracted to disaster. Acting on the advice of Circe, Odysseus took careful preparation against the Sirens. Before their ships came to where they could hear the song, Odysseus had himself tied to the mast, stopped the ears of his men with wax and ordered them to ignore his orders and gestures when they were passing the fatal is land. Soon they came in sight of the rocky is land, and the attractive song reached the ears of Odysseus. It moved him so much that he struggled in despair to free himself and shouted for his men to turn towards the rich and flowery grass land of the singing sisters. But no one paid any attention to him. The sailors kept straight on until they were completely out of hearing. Then his friends freed him and took the wax out of their ears. For once the Sirens had sung with no effects. The eldest of the sisters, Partherope, loved Odysseus so much that she threw herself into the sea after his ships had passed.
遥远的海面上有一座岛屿, 石崖边居住着唱
魔歌的海妖塞壬三姐妹。半人半岛的塞壬姐妹们坐
在一片花丛里, 唱着蛊惑人心的歌, 甜美的歌声
把过往的船只引向该岛, 然后撞上礁石船毁人亡。
过往的海员和船只都受到迷惑走向毁灭, 无一幸
免。
奥德修斯遵循女神喀耳斯的忠告。为了对付塞
壬姐妹, 他采取了谨慎的防备措施。船只还没驶到
能听到歌声的地方, 奥德修斯就令人把他拴在桅
杆上, 并吩咐手下用蜡把他们的耳朵塞住。他还告
诫他们通过死亡岛时不要理会他的命令和手势。
不久石岛就进入了他们的视线。奥德修斯听到
了迷人的歌声。
歌声如此令人神往, 他绝望地挣扎着要解除
束缚, 并向随从叫喊着要他们驶向正在繁花茂盛
的草地上唱歌的海妖姐妹, 但没人理他。海员们驾
驶船只一直向前, 直到最后再也听不到歌声。
2
这时他们才给奥德修斯松绑, 取出他们耳朵中的蜡。这次塞壬海妖们算是白唱了歌。三姐妹中的老大帕耳塞洛珀深深地爱慕着奥德修斯。当他的船只走过后, 她就投海自尽了。
