Huge Waves Destroying Arctic Ice Faster than Expected
Ice covers much of the Arctic Ocean. 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 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.
The ship travelled east and stopped next to a large block 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 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 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 waved or depend on sea ice to protect them. Wildlife like polar bears that depend on sea ice to live is also in danger.
Some scientists think people will soon see even bigger waves in icy waters. As waves break up ice, seas will be more open, waves will be stronger. There are stormy times ahead.

【分析】
这是一篇说明文，科学家们在北冰洋发现了海浪，海浪非常大，在很短的时间内将冰块破碎成更小的冰块，这使得依赖冰块生存的北极熊等野生动物处在危险之中。
1 ．
根据短文第二段 “The waves were discovered by accident in May, 2010” 可知，这些巨大的海浪是在 2019 年五月份，被科学家 “Aleksey Marchenko” 和他的学生们发现的。故答案为 In May 2010.
2 ．
根据第五段 “He decided to move the ship deeper into the ice……Soon, the waves broke up the ice around the ship into thousands of smaller pieces.” 当船移动进冰内部的时候，浪越来越大，最终把船周围的大冰块破碎成了成千的小冰块。故填 The waves broke up the ice around the ship into thousands of smaller pieces.
3 ．
根据短文第六段 “The ship's navigation system finally recorded the largest waves. They were more than 20 feet in height ” 可知，导航系统记录的最大的海浪有 20 多英尺高。故答案为 More than 20 feet.
4 ．
根据倒数第二段 “Wildlife like polar bears that depend on sea ice to live is also in danger” 可知像北极熊这样的野生动物将处于危险之中。故填 Wildlife like polar bears.
5 ．
根据最后一段 “people will soon see even bigger waves in icy waters” 可知人们将很快在冰水中看到甚至更大的波浪。故填 People will see even bigger waves in icy waters./ Bigger waves in icy waters.
