Exersice 3. Read and learn:

Departure

Ann: Well, good-bye, then! I hope you will have a pleasant journey.

Bob: I hope so too. The weather isn't too bad, anyway.

A.: No, it looks good. Just write me a-few lines when you arrive,

will you?

B. A. 3. A. B.

I will, indeed. And many thanks for your hospitality.

It was nice having you with us. When will you come again?

It is hard to say. It depends on a number of things.

Give my love to your mother.

I will.Thanks. Bye.

Bob: I think.the people of today are the most intelligent (умный)

people who have ever lived. Mary.: Before answering this question I want you to listen to the

following words: «Flying machines are possible. A man may

sit in the middle of the machine and turn some device.

This device makes the artificial wings beat the air in the

manner of a flying bird."
В.: Why have you said this? There is nothing new or interesting.

M.: But they were written six hundred years ago.

В.: Oh, really, who made this statement?

M.: Roger Bacon, an English scientist. Of course, his sentences

have been made easier, but these were his words and

thoughts. Have you heard about him?
В.: Certainly, I have heard about him. But I have thought he

was a monk (монах) and was in prison for many years.
M.: You are quite right. Besides, he made a deep study of

physics. And this was the reason (причина) for his being in

prison. He made men think about new things.
В.: Oh, Mary, I've always said you are the most clever (умный)

girl I've ever met.Do you agree with me, Peter?

Peter.: Oh, sure. And I remember Bakon's statement about cars

that can go very rapidly by their own power and great ships on rivers and oceans guided by one man.

Exercise 4. Speak about:

1. The characteristics of a new hypersonic passenger liner.

2. The main difficulties of its construction.

Use exercises 1,2 and the following words and word combinations for your topic: The text gives the information on... It is interesting to note that.. Speaking about-Further description of... is given.lt is pointed out that... As far as I know... In conclusion I'd like to say that...

Aviation designers, to display, to cover the distance, overall, to heat to a very high temperature, new generation aircraft, to overcome difficulties in, a great amount of, without using, extensive use of new materials, exceed, to solve a problem.

Exercise 5. Comment on the following statement:

Air transport has many advantages and many disadvantages.

One point of view: it is fast, comfortable, safe, it is particularly good and efficient for long distances, it is independent of roads, it is good for the health because it is not tiring (утомительно), it is the most modern means of transport and it is the best way of travelling.

A contrary point of view, it is not safe, it is not reliable, it depends on the weather, it is not always good for the health, it always takes a long time to get from and to the the airport, it is expensive, it is always connected with nervous strain (напряжение)

Exercise 6. Read and smile:

A teacher was explaining fractions to the class of girls and boys. After having written several examples on the blackboard, he asked a boy whether he would prefer (предпочитать) one-fifth or one-eighth of a lemon.

"I'd prefer one-eighth, sir."

Then the /teacher began explaining again that though the fraction one-eighth looked larger than the fraction one-fifth, it was really the smaller of the two.

"I know that, sir. I don't like lemons."

Einstein for a Day

Albert Einstein, one of the world's most brilliant and respected scientists, is best known for formulating the theory of relativity which played a critical part in the development of atomic energy. What may not be widely known is that Einstein had a fine sense of humor.

There is an amusing story about Einstein's visiting universities in a car driven by a chauffeur, giving lectures on relativity. One day the chauffeur said: "Mr. Einstein, I've heard you give this lecture about 30 times. I know it by heart, and I am sure I could give it myself." "Well, I'll give you a chance", said Einstein. "They won't recognise

me at the school. When we get there, I'll put on your cap and you introduce yourself as me and give the lecture."

The chauffeur gave Einstein's lecture without making a single mistake. On finishing, he started to leave, but one of the professors stopped him to ask a complex question. The chauffeur thought fast. "That problem is so trivial", he said, "I'm surprised that you have to ask me. In fact, to show you how simple it is. I'm going to ask my chauffeur to come up here and answer your question."
