Two summers ago I went to Changdao, a small island near Yantai. During the night, I heard strange baby-like   31        (cry). Islanders told me   32        was stray (迷路的；离群的) cats that were calling in the wild. Well, it was strange to me to see so many stray cats on such a small island. So I asked the locals  33       more details. Then they told me  34          surprising and sad story. The island is isolated in the sea and originally had no cats. Ten yers ago, when the island was developed   35       a national park, tourists began to swarm in. These visitors from all parts of the country brought in money, but the rubbish they left   36       (draw) more and more rats onto the island. Islanders therefore introduced the cats in order to get rid of the rats.   ___37        when the number of rats decreased, the number of cats increased, and the cats began to prey on birds, chickens, and fish. For more than a month after that, my mind was haunted (回响) by the plaintive crying. So now,   38       I travel, I always hear in mind what I should bring in,   39        I don’t want to bring anything that is strange,   40        (need) or even dangerous to my destination.
