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、Swim straight into the same tank.
B、Produce the appropriate sound.
C、Raise their heads above the water.
D、Press the right-hand lever first.
答案
D
解析
女士说如果灯持续亮的话,两只海豚就要按照相反的顺序按下杠杆。也就是先按下右边的杠杆.再按下左边的杠杆,所以答案为D。在第一阶段的实验中。两只海豚被放进同一水箱,A与对话不符;B、C对话中没有提到。
