Nylon was invented in the early 1930s by an American chemist, Julian Hill. Other scientists worked with his invention and finally on 27 October 1938, nylon was introduced to the world. It was cheap and strong and immediately became successful, especially in the making of ladies’ stockings.

Today, nylon is found in many things: carpets, ropes, seat belts, furniture, computers, and even spare parts of human body. It has played an important part in our lives for over 50 years. Next year, about 36 million tons of it will be manufactured.

Giup minh vs nha!!

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

C These messages could be sent very quickly.

D The new republic faced enemies on all sides in the form of the forces of Britain, Austria, Holland, Prussia and Spain.

E In August 1794, it carried its first message, the news of Napoleon's victory at Le Quenoy.

F A system was built between London and the south coast, and other countries followed.

War has been called 'the mother of invention', and this was certainly true in the French Revolutionary wars in 1792. 1 | D | What the Revolutionary Government urgently needed was a reliable system of communication.

Claude Chappe, who was a priest and an engineer, had developed a telegraph system, but had not been able to test it fully. 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

I. There is a mistake in each of these sentences . Underline the mistake and then correct it

1. The weather was bad but => so we didn't go on a picnic

2. My father was => X used to travel a lot but he doesn't anymore

3. We live in the city so me => I don't like it

4. Mary has to stay in bed because of she is sick => her sickness

5. They took a boat and it would reach => reached the place for one hour

6. Ba hurt => hurt his foot during he was climbing down the boat

7. The great earthquake has => was destroyed San Francisco in 1906

8. The volunteer taught the local people what => how to read and write

9. He believed everything would be well => good after he left

10. The way to the beach was to => so long that it took them an hour to walk there
