Dolphins are interesting animals. Working with them is fun, because you never know what they will come up with to surprise you.
Remember when your mom used to cut up your food? Circe, a show dolphin, won" t eat fish unless someone cuts the fins(鱼鳍) off. Diana Reiss, a scientist who worked with Circe, knew that. But one day she forgot.
Reiss was training Circe to " stay at station" in front of her. Every time the dolphin swam off, Reiss gave her a time-out by backing away from the side of the pool and standing at a distance. When Circe stayed, Reiss fed her a piece of fish. But then she gave her a piece with fins by mis-take.
Circe looked at Reiss, spat(吐) out the fish, and swam across the pool. She took an upright position in the water and simply " stood" there. Circe was communicating(交流) loud and clear. "I felt as if I had gotten the time-out ! " says Reiss.
Another dolphin, Pete, enjoyed his meals of fish served up by his trainer. But a wild bird star- ted to show up at every feeding to steal some of the dolphin" s supper. Pete was definitely not hap-py about that.
One day when Pete" s trainer gave him frozen fish, Pete let them sink to the bottom of his pool. Between shows he dived down and pushed eight fish up to the surface, and managed to keep all of them afloat. For five minutes, the bird watched anxiously. Finally, the bird took the bait. When it did, Pete caught the bird" s feet and pulled it underwaterl Then took care of that little thief.
69. Reiss would feed Circe a fish _________.
[ A] before Circe gave a performance
[ B ] when Circe followed the instruction
[C] the moment Circe swam close to Reiss
[D] each time Reiss left the side of the pool请帮忙给出正确答案和分析,谢谢!
参考答案
正确答案:B
6参考译文D海豚是一种有趣的动物。与它们一起工作是非常有趣的,因为你从来都不知道它们会做出什么令你惊讶不已的事情。还记得你妈妈过去常常切碎你的食物吗?瑟茜,一只表演海豚,它只吃刮掉了鱼鳍的鱼。一位名为戴安娜·瑞斯的科学家与瑟茜一起工作,并知道它的这一习性。但是,有一天她忘了。瑞斯训练瑟茜呆在她面前原地不动。每一次瑟茜游走,瑞斯都会退离池边,站到稍远的地方,给它一个暂停。如果瑟茜呆在原地不动,瑞斯就会喂它一条鱼。但是那次由于粗心她把一条带鱼鳍的鱼给了瑟茜。瑟茜看了看瑞斯,把鱼从嘴中吐了出来,并在池中游来游去。她从水中径直伸出头来,身体只是直立在水中。瑟茜发出大声且清晰的声音与瑞斯进行交流。瑞斯说:“我感觉时间好像在那一刻停止了。”另一只名为皮特的海豚,非常喜欢饲养员喂给它的鱼食。但是每一次进食的时候,一只野鸟都会出现并抢走皮特的一些晚餐。皮特当然很不高兴。一天饲养员喂给皮特一些冷冻鱼,皮特把这些食物沉入池底。表演的时候皮特潜入水底,把八条鱼推出水面,并使这八条鱼都浮在水面上。五分钟过去了,那只鸟焦急地观望着。最终,那只鸟上当了。这时皮特抓住鸟的脚并把它拖入水中,然后处理这只小小的贼。69.B【精析】细节题。文中第三段第三句提到“WhenCircestayed,Reissfedherapieceoffish.”当瑟茜听从指令呆在原地不动的时候,瑞斯会喂鱼给它吃。故选B。
