Прочитайте и переведите без словаря.То understand why light from the laser is so concentrated, youmust know that light travels in waves.
Ordinary white light is madeup of many wavelengths travelling in every direction. Laser light isessentially of one wavelength, with all the waves moving in one direction. Because the laser wavelengths intensify each other, theycan remain in an unbelievably straight beam for a long distance. Almost any substance can be forced to «lase» if you work hard enoughwith it. Gas lasers give off continuous beams of light. Tiny semiconductor lasers may be especially useful in computers for transmitting signals to replace the use of cables.
Many lasers can give offinvisible radiation, either infrared or ultraviolet.CONVERSATIONExercise 1. Answer the questions.1. What is a laser? (a device producing an intensive beam oflight) 2. What is its principle of operation? (light amplification bystimulated emission of radiation) 3.
What light is produced by a laser? (light of pure single colour) 4. What can be done by means of alaser? (vaporizing the hardest materials) 5. What materials can betreated with a laser? (practically any material and any substance)6. What is the most promising use of lasers? (the use in all kinds ofcommunication) 7. What prevents putting into effect the projectsto use lasers more widely in space? (great technological difficultiesand great cost involved)Exercise 2. Make a sentence out of the two parts.1.

It isa pity you didn't join me when I was taking speed-readingcourse.M.: Two things hold me back.
Doubts that any system could radically and permanently increase my speed.

The only wide survey (опрос) ofex-students — 1800 of them — showed that after a year onethird of the people weren't using the method at all. Anotherthird said they use it sometimes and that probably they havekept speed. But the rest of the students said they were readingfaster than a year later.B. Answer the following questions:1. Are you a fast or a slow reader?2. In what situations can fast reading be useful in your opinion?3. Would you like to improve your reading speed? Why?4. Can all books be read quickly? Why (not)?Exercise 4. Comment on the following statement.Every student ought to be able to read very fast.One point of view: Reading requires thought; one needs time for thinking, readingought to be a kind of dialogue with the author — this requires time; quaUty is more important than quantity.204А contrary point of view : Fast reading does not mean careless reading, nothing isleft out, thinking can be very fast, fast reading is reading for meaning, it saves time(экономить) also for thinking, it is very important for a person to get a great deal ofinformation in as little time as possible.Exercise 5.
