Jane: Hi, Fred. Why aren’t you going home? What are you looking for?

Fred: I can’t find my pad. I remember using it at the science lesson, but where is it now?

Jane: If you used it in class, it must be here, in the classroom. Have you looked inside the desk?

Fred: That’s a good idea. Eureka [juˈriːkə]! Here it is! Thanks a lot, Jane.

Jane: I’m glad you’ve found it. But what is “Eureka”?

Fred: There’s a legend that the word was used by Archimedes [ɑːkɪˈmiːdɪz], the Greek mathematician and inventor. Once the king of Syracuse, the place where Archimedes lived, told him to find out if the king’s gold crown had any silver in it. Archimedes thought about it for a long time but one day he stepped into his bath, noticed the rise of water and solved the problem. After that he ran through the streets crying “Eureka!” which means “I have found” or something like that.

Jane: I see. I’m sure it has to do with Archimedes’ famous principle. I remember it from our science class last week, “any object put into a liquid is kept floating in it by a force equal to the weight of the liquid displaced.”

Fred: Excellent! Archimedes really used that principle to solve the problem of the crown. He put gold and silver into water to see the difference in the rise of water.

Jane: How clever of him! What else is he famous for?

Fred: If I remember right, he invented some devices which the Greeks used in warfare. At that time the Roman army was attacking the city of Syracuse by land and sea. They were not able to get into the city for nearly three years thanks to the inventions of Archimedes. He also wrote books on geometry and physics.

Jane: Fred, you seem to know a lot about the man. Tell me some more, please.

Fred: I’ve always been interested in the history of science. What else can I tell you? Let me see... Maybe about his death. There is another legend which says that Archimedes was killed by a Roman soldier when the army finally entered the city. The great scientist didn’t notice the soldier come close because he was busy working on some mathematical problem.

1. Jane and Fred were talking inside the school building.

2. Archimedes cried “Eureka!” because he had found the answer to the king’s question.

3. Jane had learned about Archimedes’ principle from her textbook.

4. Archimedes discovered that the king’s crown was made of gold and silver.

5. Archimedes helped the people of Syracuse to defeat the enemies.

6. Archimedes died at the hands of an enemy.

Lake Baikal

Scientists say that Lake Baikal is the oldest lake on planet Earth. Usually lakes don't live longer than a million years but this wonderful lake is more than 25 million years old! For scientists it is a living laboratory of evolution.

Lake Baikal is also the deepest lake in the world, it is 1,637 metres deep from top to bottom. With time the lake becomes wider and deeper. There is a theory that Lake Baikal is the beginning of a new ocean. The lake holds one-fifth of the planet's fresh water and this water is incredibly clean.

Lake Baikal is one of the most beautiful places on the Earth. Everyone who has been on its shores knows how unusual and how mighty it looks. The lake is very difficult to describe: its clear waters change colours all the time. The snows of Siberia come to Lake Baikal in early October. At the end of October ice begins to appear on its surface. In winter the ice gets very thick — well over a metre. (In 1904, during the Russo-Japanese War they laid a railway across the ice to carry guns to the front and the ice didn't break under its weight.) In April the ice begins to turn into water and the lake becomes so large that sailors and fishermen here talk of "going to sea".

The water in the lake is never warm. In summer its temperature is about +12 degrees. But a lot of people still enjoy swimming in it. They say swimming in the waters of the lake is good for their health. Lake Baikal is a living museum of water plants and animals. About 1,500 species of animals here are endemic. Endemic means that you cannot see them anywhere else in the world. The lake is rich in life. Its waters move vertically, carrying oxygen to the very bottom. The lake still keeps a lot of secrets from people. One great mystery about the lake is how nerpa, the Baikal seal, appeared in the lake which is hundreds of kilometers from any ocean, and made the lake its habitat.

The lake lies among beautiful mountains. The Baikal Mountains on the north shore and the taiga belong to a national park. The greatest problem here is to keep all this natural beauty and protect the lake from pollution. Every year the lake attracts more and more tourists, so the task is not at all easy.

1. Lake Baikal can help people to understand how life developed on our planet.

2. The size of the lake changes with time.

3. The water in the lake is very clean but cold, so people don't swim in it.

4. The lake has a number of islands — big and small.

5. The lake's flora and fauna make it unique.

6. Some ocean animals live in the lake.

7. Now people are thinking of organizing the first national park on the shores of the lake.
