W: One of the most interesting experiments with dolphins must be one done by Doctor Jarvis Bastian. What he tried to do was to teach a male dolphin called Bass and a female called Doris to communicate with each other across a solid barrier.
M: So how did he do it exactly?
W: Well, first of all, he kept the two dolphins together in the same tank and taught them to press levers whenever they saw a light. The levers were fitted to the side of the tank next to each other. If the light flashed on and off several times, the dolphins were supposed to press the left-hand lever followed by the right-hand one. If the light was kept steady, the dolphins were supposed to press the levers in reverse order. Whenever they responded correctly, they were rewarded with fish.
M: Sounds terribly complicated.
W: Well, that was the first stage. In the second stage, Doctor Bastian separated the dolphins into two tanks. They could still hear one another, but they couldn’t actually see each other. The levers and light were set up in exactly the same way except that this time it was only Doris who could see the light indicating which lever to press first. But in order to get their fish, both dolphins had to press the levers in the correct order. This meant, of course, that Doris had to tell Bass whether it was a flashing light or whether it was a steady light.
M: So did it work?
W: Well, amazingly enough, the dolphins achieved a 100% success rate.
1. What is the purpose of Doctor Jarvis Bastion’s experiment?
2. What were the dolphins supposed to do when they saw a steady light?
3. How did the second stage of the experiment differ from the first stage?
4. What should the dolphins do to get rewarded?
选项
A、Both of them press the lever at the same time.
B、One of them presses the right-hand lever first.
C、One of them presses the levers in the right order.
D、Both of them have to press the levers correctly.
答案
D
解析
女士在介绍实验的工作原理之后说到,当海豚做出正确的回应。它们就会被奖励鱼吃。然后在实验第二阶段也谈到。要得到鱼的话,两只海豚都要能以正确的顺序来按杠杆。故D项正确。A中的“同时按杠杆”没有在对话中提及,不选;女士强调两只都要能正确按下杠杆才能吃到鱼。而不是B和C项所说的“One of them”,所以都予以排除。
