I've just been to see a film called Touching the Void. It's about two climbers who decided to go climbing in the mountains in Peru. It took them two days to reach the mountain they had been decided to climb because it was in such a remote place. They left a companion and the most of their supplies at a base camp, optimisstically thinking about they would be back in a couple of days. After a difficult climb, they reached at the top of the mountain. It was then that everything started to go wrong. Because of one climber had broken his leg, he had to be lowered down the mountain by means of a rope. His leg it was so much painful that he couldn't stand on it. After a very exciting bit of the film, which I won't describe, he found by himself alone at the bottom of a crevasse. He managed to climb out and eventually crawl to safety. The cold was so intense that he got frostbite in his hands, but he was carried on, dragging himself down a glacer and accross rocks. When he arrived at the base camp, his friends were too amazed to see him. They couldn't believe that in despite his broken leg, he had managed to reach the camp.

Until that October I had never even seen Laerg. This unity seem strange, considering my father was born there and that I’d been half in love with it since I was a child. But Laerg isn’t the sort of place you can visit easily. The small island group is eighty miles west of the Outer Hebrides. Eighty sea miles may be no great distance, but this sea is the North Atlantic and the seven islands are a lonely group standing in the way of the great storms that sweep up towards Iceland and the Barents Sea.

Oddly enough, it wasn’t my father who’d made me want to go to Laerg. He seldom talked of the island. He’d become a sailor as a young man and then married a girl from Glasgow and settled down after surviving a shipwreck in mid-Atlantic but losing his confidence in the sea. It was Grandfather Ross who filled our heads with his talk of island history.

This old man with a fierce face and huge hands had been a powerful influence on both my brother lain and myself. He’d come to live within us when everyone left the island. He had been the only man to vote against leaving when the Laerg Parliament made its decision, and to the day he died he disliked living on the mainland. It wasn’t only that he talked endlessly of Laerg, in the years he stayed with us he taught my brother and myself everything he knew about the way to live on that island of rock, sheep and birds.

I’d tried to get there once a long time ago, hiding away on fishing boat. But on that trip the boat hadn’t gone within a hundred miles of Laerg, and then I joined Iain, working in a Glasgow factory. A year in the Navy followed, and then ten years at sea, and after that I had started the thing I had always wanted to do – I began to study as a painter. It was during a winter spent in the Aegean Islands that I suddenly realized Laerg was the subject that most attracted me. It had never been painted, at least not the way my grandfather had described it. I’d packed up at once and returned to England, but by then Laerg had become a tracking station for the new missile developments. It was a closed island, forbidden to unauthorized visitors, and the Army would not give me permission to visit it.

That was the position until October in the following year when a man called Lane came to my house. It was just after ten in time morning that the phone rang, and a man's voice, rather soft, said, "Mr.Ross? My name's Ed lane. Are you by any chance related to Iain Ross, reported lost when the Duart Castle sank twenty years ago?" "He was my brother."

"He was? Well that's fine. I didn't expect to find you that fast. You're only the fifth Ross I've telephoned. I'll be with you in an hour. OK?" And he'd rung off,

leaving me wondering what in the world it was all about.

I was working on another book cover for Alee Robinson, but after that phone call I'd found it impossible to go back to it. I went into the kitchenette and made myself some coffee. And after that I stood drinking it at the window, looking out across the rooftops, an endless view of chimneys and TV aerials. I was thinking of my brother, of how I'd loved him and hated him, of how there had been nobody else in my life who had made up for the loss I'd felt at his going.

2. At the time of Ed Lane’s telephone call, who was on the island of Laerg?

3. What makes the island of Laerg difficult to get to?

A. The distance form the mainland

B. The atlantic weather

C. It is so rocky

D. Boats do not call there

4. Mr.Ross’s father settled down on the mainland because

A. He had been told to move from the island

IV. Read the following passage and choose the best answer from A,B, C or D:I had feared that my companion would talk, but it was soon plain (rõ ràng) that there was no such danger. Two days passed during which we did not exchange a single word. He seemed, indeed, absolutely unaware of my presence. He neither read nor wrote, but spent most of his time sitting at the table and looking out of the window across the pleasant parkland that surrounded the house. He sometimes talked to himself and said things half under his breath. He bit his nails and once he produced a penknife and dug holes in the furniture until one of the attendants (nhân viên) took it from him. I thought at first that perhaps he was mentally ill. During the second day I even began to feel a little nervous of him. He was extremely large, both broad and tall, with very wide shoulders and enormous hands. His huge head was usually sunk low between his shoulders. He had dark, rather untidy hair and a big shapeless mouth which open very now and then. Once or twice he began singing to himself, but broke off abruptly (bất ngờ) on each occasion - and this was the nearest he seemed to get to noticing my presence.
By the evening of the second day I was completely unable to go on with my work. Out of a mixture of nervousness and curiosity, I sat, too looking out of my window and blowing my nose, and wondering how to set about establishing the human contact which was by now becoming an absolute necessity. It ended of with my asking him for his name. He had been introduced to me when he arrived, but I had paid
no attention then. He turned towards me a very gently pair of dark eyes and said his name: Huge Belfounder. He added:" I thought you didn't want to talk." I said that I was not at all against talking, that I had just been rather busy with something when he arrived, and I begged his pardon if I had appeared rude.
It seemed to me, even from the way he spoke, that he was not only mentally ill, but was highly intelligent; and I began, almost automatically, to pack up my papers. I knew that from now on I should do no more work. I was sharing a room with a person of the greatest fascination.

1. How did Huge spend the first two days?
A. He worked as if the writer was not there.
B. He talked and sang to himself from time to time.
C. He spent his time making holes in the furniture.
D. He kept annoying the attendants.
2. On the second evening the writer
A. tried in vain to start a conversation.
B. was feeling bored.
C. began to fell frightened of his companion.
D. could not concentrate on his work.
3. Huge didn't talk to the writer at first because
A. he didn't realise the writer wished to.
B. he thought the writer was rude.
C. he was feeling ill.
D. he was too busy.
4. The writer's attitude to Huge changed from
A. fear to nervousness.
B. nervousness to interest.
C. curiosity to nervousness.
D. nervousness to unfriendliness

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

Read the text on the tight about the invention of semaphore. Five sentences have been removed. Choose from sentences A-F the one which fits each gap (l-4).There is one extra sentence which you do not need. There is an example at the beginning (0).

A Using ropes, these could be moved to form 49 different shapes that could be recognized easily.

B The main problem was that it could not be used during the night or on foggy days.

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.
