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

However, his brother Ignace was a member of the government, and arranged for Claude's system to be tested. It turned out to be a great success and started a new form of high-speed communication.

The two brothers had a series of towers built 5 to 10 km apart. At the top of each tower was a tall wooden mast, and they attached one horizontal and two vertical wooden beams to this mast. Claude called this system 'semaphore', which comes from the Greek meaning 'bearing a sign'. 2 ( )

Operators in each tower watched neighbouring towers through a telescope and then passed the message on to the next one in the line. The first line stretched from Paris to Lille, a distance of 2.40 km. 3 ( ). At an average speed of three signals a minute, it was carried in 20 minutes, more than 90 times faster than messengers on horseback.

Once the value of Chappe's system was understood, it soon became the standard method of communication in Europe. 4 ( ). By the time the electric telegraph was developed, France had more than 550 semaphore towers stretching 4,800km.

Unfortunately, Chappe's system had some disadvantages. 5 ( ) The towers were also expensive to maintain and the cost of staff was high. In the end, Chappe was depressed by these criticisms of his inventions and by claims from other engineers that they had invented semaphore, and he committed suicide in 1805.

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
