對話一
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.
W: 最有趣的海豚實驗之一一定是由賈維斯·巴斯蒂安博士做的。他試圖教公海豚巴斯和母海豚桃瑞絲透過堅固的屏障交談。
M: So how did he do it exactly?
M: 他具體是怎么做的？
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.
W: 首先他將兩個海豚放在同一水槽中，教它們在看到光亮的時候按壓杠桿。杠桿在挨著它們的水槽邊上。如果燈光是時不時的閃爍幾下，那么海豚應(yīng)該按壓左手邊的杠桿，然后是右手邊。如果燈光是持續(xù)的，那么海豚應(yīng)該以相反的順序按壓。當(dāng)他們回應(yīng)正確時，就會有魚作為獎勵。
M: Sounds terribly complicated.
M: 聽起來很復(fù)雜。
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.
W: 這是第一步。第二步的時候，巴斯蒂安博士把海豚分到兩個水槽。它們可以互相聽到但不能看到彼此。
W: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.
W:杠桿和燈光的設(shè)置跟原來一樣，不過這次只有桃瑞絲能看到燈光并按壓杠桿。為了得到魚吃，兩只海豚都得以正確的順序按壓杠桿才行。
W:This meant of course that Doris had to tell Bass whether it was a flashing light or whether it was a steady light.
W:這就意味著桃瑞絲得告訴巴斯到底是閃爍的光還是持續(xù)的光。
M: So did it work?
M:那么管用嗎？
W: Well, amazingly enough, the dolphins achieved a 100 % success rate.
W: 令人震驚的是，海豚的成功率是100%。
