Упражнение 5. Прочитайте, запомните выделенные слова.

Do you know what the words either and neither mean?

Yes, I do. Either means каждый, любой, любой из двух, while

neither stands for ни один, ни один (из).

That's correct. Can you give examples?

Yes I can. For example: There is a number of lecture rooms on either side of the corridor. Which of these dictionaries can be used for translating a technical article? You may use either. And in what way is either translated when it is used with or? For instance: «Please, bring some dictionaries either from the library or from the reading room.» Either... or... means либо... либо, или... или. Now let us speak about neither, it is the negative form of either, meaning ни тот... ни другой. For instance: I was offered two books, but I took neither of them, as I did not like them. And neither connected with nor means ни... ни, for example: These problems seemed difficult neither to my friend, nor to me. Are these words used in any other way?

Yes, they may be used in short negative sentences such as: «I don't like this book», said Peter. «Neither do I», said Ann, which means мне тоже (не нравится). I shall not go to the library to­morrow. He won't go either. Он тоже (не пойдет).

5. Aerodynamics is one more problem to be taken into consider­ation when designing a hypersonic craft. 6. The wheel-computer­ized system is much more efficient than those used previously. 7. Cryogenic fuels used both as coolant and propellant make the so­lution of the superliner surface cooling problem much easier to solve. 8. The fact that dirigibles are much larger in size and their staying power is much longer than those of an aircraft makes them ideally suited for exploration.
