Lucy found a wild beehive inside a tree in Northern Kenya and set up a recorder. Then she threw a
stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next, Lucy searched out elephant families in Samburu National Reserve in Northern Kenya and put a speaker in a tree close to each family. 返回目录 专题二十 时闻型阅读理解 真 题 典 例
From a distance, Lucy switched on the prerecorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall(瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. 返回目录 专题二十 时闻型阅读理解 真 题 典 例
