One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. He was standing at the edge of one of tanks where several of these highly intelligent, friendly creatures were kept. Elvar had just swum up alongside him and had turned on his back. He wanted Sagan to scratch his stomach again, as the astronomer had done twice before. But this time Elvar was too deep in the water for Sagan to reach him. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water into the air and made a sound just like the words "More!"
The astonished astronomer went to the director of the institute and told him about the incident.
"Oh, yes. That´s one of the words he knows," the director said, showing no surprise at all.
Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a "language", in the real sense of the word? Scientist don´t agree on this.
1/ The dolphin leapt into the air because
A. Sagan was too near the water
B. it was part of the game they were playing.
C. he wanted Sagan to scratch him again
D. Sagan wanted to communicate with him
2/ "Dolphins" brains are particularly well developed to
A. help them to travle fast in water
B. arrange sounds in different structures
C. respond to different kinds of sound
D. communicate with humans through sound
Our oceans are becoming extremely polluted. Most of this pollution comes from the land, which means it comes from people. Firstly, there is raw sewage, which is pumped directly into the sea. Many countries, both developed and developing, are guilty of doing this. Secondly, ships drop about 6 million tons of garbage into the sea each year. Thirdly, there are oil spills from ships. A ship has an accident and oil leaks from the vessel. This not only pollutes the water, but it also kills marine life. Next, there are waste materials from factories. Without proper regulations, factory owners let the waste run directly into the rivers, which then leads to the sea. And finally, oil is washed from land. This can be the result of carelessness or a deliberate dumping of waste.
