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 mistake.
Circe looked at Reiss, spat(吐) out the fish, and swam across the pool. She took an upright position in the water and simple "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 started to show up at every feeding to steal some of the dolphin’s supper. Pete was definitely not happy 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 underwater! Then he took care of that little thief.
Reiss would feed Circe a fish ______.
选项
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
答案
B
解析
分析推理题。短文第三段描述了Reiss这位科学家训练海豚的过程(或者具体方法)。其中第二、三句指出,Reiss先是给海豚一个停止指令(Reiss gave her a time-out),而当海豚停下来时,就给海豚一条鱼吃(When Circe stayed, Reiss fed her a piece of fish)。这一过程就是让海豚Circe-按照指令去做(follow the instruction),故本题正确答案为[B]。
