Huge Waves Destroying Arctic Ice Faster than Expected

Ice covers much of the Arctic Ocean（北冰洋）. Some pieces of ice are huge, like moving islands. As temperatures have increased, however, some of the ice has begun to disappear. Scientists have discovered huge waves（海浪）in the arctic waters.

The waves were discovered by accident in May, 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters.

On May 2, the ship traveled east and stopped next to a large chunk of ice around 50 miles from the small island of Hopen. Marchenko prepared to lead his students out onto the Ice.

"We were ready to go but when I went out, I discovered many cracks（裂縫）around," he remembers.

He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces．

Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship's navigation（航行）system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists had never imagined that the process could happen so fast. The waves in these areas used to be small.

The speed and force of the huge waves there makes it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears and walruses that depend on sea ice to live is also in danger.

Some scientists think people will soon see even bigger waves in these icy waters. As waves break up ice, the seas will become more open, and the waves will get even stronger. There are stormy times ahead.

【1】When did Marchenko and his students discover huge waves in the arctic waters?

【5】What is Paragraph 7 mainly about?

Answer 1

【答案】

【1】In May.2010.

【2】Because they wanted to study the icy waters.

【3】He moved the ship deeper into the ice.

【4】More than 20 feet.

【5】The damage of the huge waters to people and wildlife in Arctic.

【解析】

這篇短文講述的是科學(xué)家們在北冰洋發(fā)現(xiàn)了海浪，海浪非常大，迫使巨大的冰塊上下跳躍，在很短的時(shí)間內(nèi)將冰塊破碎成更小的冰塊，而隨著冰塊的減少，海浪就會(huì)變得更大，這使得依賴冰塊生存的北極熊、海象等野生動(dòng)物處在危險(xiǎn)之中。

【1】根據(jù)短文第二段開頭The waves were discovered by accident in May, 2010.可知，這些巨大的海浪是在2019年五月份，被科學(xué)家Aleksey Marchenko和他的學(xué)生們發(fā)現(xiàn)的。故答案為In May 2010.

【2】根據(jù)短文第二段中Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters.可知，Marchenko和他的學(xué)生想要研究冰冷的海水。故答案為Because they wanted to study the icy waters.

【3】根據(jù)短文第五段He decided to move the ship deeper into the ice to keep safe.可知，為了安全，Marchenko決定把船開到冰更深的地方。故回答He moved the ship deeper into the ice.

【4】根據(jù)短文第六段The ship's navigation（航行）system finally recorded the largest waves. They were more than 20 feet in height.可知，導(dǎo)航系統(tǒng)記錄的最大的海浪有20多英尺高。故答案為More than 20 feet.

【5】根據(jù)短文第七段That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears and walruses that depend on sea ice to live is also in danger.可知，這一段中主要介紹了巨大的海浪對(duì)航海人員、當(dāng)?shù)厣鐓^(qū)以及野生動(dòng)物的危害。故答案為The damage of the huge waters to people and wildlife in Arctic.

這是一篇科普說明文，短文中講述了在北冰洋海域發(fā)現(xiàn)巨大海浪的過程，以及巨大海浪對(duì)人類以及野生動(dòng)物的危害。文章主題明確，結(jié)構(gòu)清晰，但短文中句式結(jié)構(gòu)復(fù)雜，內(nèi)容離學(xué)生們的日常生活較遠(yuǎn)，在理解上有一定的難度。題型是任務(wù)型閱讀，要求根據(jù)文意回答問題，考查學(xué)生們對(duì)文章事實(shí)細(xì)節(jié)的理解。做題時(shí)，應(yīng)先通讀短文，了解文章大意；然后根據(jù)題目所問鎖定文章相關(guān)段落或語句作答。例如第1小題，題目問的是發(fā)現(xiàn)海浪的時(shí)間，注意在短文中搜索數(shù)字、月份等關(guān)鍵詞信息，根據(jù)第二段The waves were discovered by accident in May, 2010可知答案。第4小題同理，注意數(shù)字和關(guān)鍵詞the largest waves。
