二、语篇阅读训练
Ⅰ.阅读理解
Herman Melvile, the writer of the famous whale story Moby Dick, once wrote that humpback whales were “the most light-hearted of all the whales.” Known to be intelligent animals and can be seen working together to hunt schools of small fish, humpbacks are a favorite of whale watchers everywhere. And, if you listen closely, you might even hear one singing.
Marine (海洋) biologist Jim Darling has studied the songs of humpback whales for more than 25 years. While recording whale songs on a boat near Hawaii, he invited author Douglas Chadwick to experience diving with a humpback. In the water, Chadwick heard the whale's songs in a way he never heard them before. “Suddenly, I no longer heard the whale's voice in my ears，” he said. “I felt it inside my head and bones.” When swimming with the whale, Chadwick could see that the whale was aware of him, but not alarmed by his presence. Up in the boat, Darling recorded the whale's song, which can be long and complex, sometimes lasting for 30 minutes or more. Actually, they are perhaps the longest songs sung by any animal.
Darling says that only male humpbacks sing, but for unknown reasons, it was previously thought that they sang to attract females, but scientists showed this was incorrect when they played recordings of whale songs in the ocean and the female whales did not respond. Another idea is that male humpbacks compete with each other using songs, just as other male animals on land do using their horns or sharp teeth.
Researchers have also found that humpback whale songs are different in different parts of the world, perhaps like whale national songs. They may also be like hit tunes on the radio, changing over time — from one year to the next, or even over a single breeding season when they produce young.
Another member of the research team, photographer Flip Nicklin, recalls a special moment he had while interacting with a humpback. While he was snorkeling(潜水) some distance from the huge animal, it approached him until it was just a few metres away. It then gently carried Nicklin towards its eye with a flipper (鳍肢), as if examine him. Obviously, the urge to understand a different species goes both ways.

语篇解读：本文是一篇说明文。文章首先向我们展示了鲸鱼数量回升的好现象，接着又讲述了鲸鱼由于被捕杀濒临灭绝的历史以及人们为了保护鲸鱼所作出的努力，最后告诉我们鲸鱼数量的现状以及我们仍需做的努力。
1．选C 根据空格前一句“In the past years, humpback whales have been spotted in the two rivers surrounding the island of Manhattan, the Hudson River and the East River”可知，在过去的几年里，在两条环绕曼哈顿岛，哈得孙河和东河的两条河流里，已经发现了座头鲸，而选项C中“Last year, one even swam past where the mayor lives.(去年，有一只甚至从市长住的地方游过)”，在意思上正好与其相承接，故选C。
2．选E 根据空格前一句“Fish are on the humpback's menu.”可知，增加的鱼成了座头鲸的菜单，而选项E“The extra food in the rivers is mainly what's attracting the whales.(河中额外的食物是吸引鲸鱼的主要原因)”，这里“额外的食物”就是“增加的鱼”，故选E。
3．选A 空格前讲的都是人们为保护鲸鱼所作出的努力，空格后“Last September, it was announced that nine groups of humpback whales are no longer endangered.(去年九月宣布九组鲸鱼不再处于濒临灭绝的境地)”，可知人们的努力得到回报，故选A。
4．选D 根据空格后“The number of them ...”，可知空格处应该涉及鲸鱼的数量，故选D。
