Grammar Review
Модальные глаголы can (could), may (might), must не обозначают действия, а выражают отношение к нему, т.е. возможность, вероятность или необходимость совершения действия. Само действие выражается инфинитивом смыслового глагола без частицы to.

I can translate this article without a dictionary.	Я могу перевести эту статью без словаря.
You may come here every day.	Ты можешь приходить сюда каждый день.
They must meet him.	Они должны встретить его.

У этих модальных глаголов есть эквиваленты, которые используются взамен отсутствующих временных форм этих модальных глаголов.

can = be able to

may =be allowed to

must = have to, be to

We will be able to see each other very often.	Мы сможем видеться очень часто.
He will be allowed to borrow books from this library.	Он сможет взять книги из этой библиотеки.
He had to work hard to pass his examination.	Он должен был работать усердно, чтобы сдать свои экзамены.
We were to inspect the new devices.	Мы должны были проверить новые приборы.

В пассивном залоге (Passive Voice) в отличие от активного залога подлежащее не совершает действия, а испытывает какое-то действие на себе. Пассивный залог образуется по следующей формуле: to be + 3fV, где to be является вспомогательным глаголом и изменяется по временам.

Пассивные конструкции переводятся возвратным глаголом (строится) и неопределенно-личным предложением (строят).

This problem is discussed at the conference.	Эта проблема обсуждается на конференции.
His lectures were always listened to with great attention.	Его лекции всегда слушали с большим вниманием.

3. Read and memorize the following word combinations:
a number of = a set of – ряд, несколько, некоторое количество

per second – в секунду

a particular memory location or cell – особая ячейка памяти

its own unique address – свой собственный уникальный адрес

instead [in'sted] of saying – вместо того, чтобы сказать

to take a square root – извлекать квадратный корень

to raise to a power – возводить в степень

TEXT A

INFORMATION, MACHINE WORDS, INSTRUCTIONS, ADDRESSES AND REASONABLE OPERATIONS

1. Information is a set of marks or signs that have meaning. These consist of letters or numbers, digits or characters, typewriter signs, other kinds of signs, and so on. A computer reacts differently to different digits or characters, and reacts to them as units that have meaning. For example, information for an analog computer has to be in the form of distances, or rotations, or voltages, or other physical variables. And for a digital computer information has to be in the form of digits or numbers.

2. Any information may be represented by the binary system including two digits: one (1) and zero (0). Each 1 and 0 is a separate binary digit called a bit. A bit is the smallest part of information. Bits are typically grouped in units that are called bytes. A byte is the basic unit of information used in modern computers and consists of eight bits.

3. The bytes are handled usually in standard groups called machine words or just words. There are two basic types of information or words that can be put into a memory cell or location: words that are numerical quantities and words that are computer instructions. Regularly, an instruction to the machine is expressed as a word; and so the same set of characters may have meaning sometimes as a number, sometimes as an instruction. A speed of 96,000 characters per second is the same as a speed of 8,000 words per second. Most human beings could not take even 12-digit number per second.

4. Physically the set of bits is a set of arrangements of some physical equipment. One of the ways of storing information in a computer is storing by using a set of small magnetically polarized spots on a magnetic surface.

5. The computer is told what operations to perform by means of instructions. An instruction is a command to the computer. It consists of a verb (an operational code) and a noun (an operand). For example, if the computer is instructed "Add 365 the number of times stated in the register R", and if the register R stores the code for number 3, then the computer will perform that operation three times. An instruction word looks like a number, and there is no way to tell from the word itself whether it is a quantity or an instruction. The computer must be told exactly which address contains an instruction and which contains a quantity.

6. An address is the name of particular memory location or cell. Each memory location (word or byte) has its own unique address or number just like a post office box. For example, if the computer contains 100 memory cells, their respective addresses might be the numbers from 1 to 100 (or 0 through 99). And instead of saying "A word is in a memory cell", the computer personnel say, "The contents of an address аre a word."

7. Reasonable operations are mathematical and logical. Mathematical operations include arithmetic and algebraic operations. Arithmetic operations are addition, subtraction, multiplication, division, taking a square root, etc.; and algebraic operations are called rising to a power as well as differentiating and integrating.

8. Logical operations include comparing, selecting, sorting, matching, etc. These are operations which may be performed either on numbers, or on expressions consisted of letters such as ordinary words. A very important logical operation performed by a computer is determining, i.e., which of two operations is to be performed next.
Notes:
numerical quantities – численные значения (величины)

Most human beings could not take even 12-digit number per second – большинство людей не смогли бы воспринять даже 12-значное число в секунду

their respective addresses might be the numbers – их соответственные адреса могли бы быть числами

HOW MUCH SHOULD AN EDUCATED MAN KNOW ABOUT COMPUTERS?

Some years ago in the United States of America a discussion on the question what an educated man is was organized. At this discussion one of the definitions of an 'educated man' was this:

An educated man:

– is able to read, write, and do arithmetics;

– has a basic knowledge of the history and geography of world and man;

– understands the scientific method, and has an elementary knowledge of at least one science;

– has an elementary knowledge of mathematics and logic, what they are, and how to use them;

– knows at least one other language besides his own well enough to read it and talk a little in it;

– can say what he means in suitable words both speaking and writing;

– is able to listen, knows how to learn, enjoys learning;

– never forgets that his views and opinions may be wrong, and is always ready to change them on evidence;

– has an elementary knowledge of computers and programming, and some active experience with a whole computer is highly desirable.

An educated man of 200 years ago in the United States did not need to know anything about science. An educated man of 25-30 years ago did not need to know anything about computers. But an educated man of today needs to have at least some significant knowledge of science, and at least a little significant knowledge about computers.

The summary knowledge that an educated man should know about computers could be put down on ten sheets of paper, in about 3,000 words.
Notes:
an educated man – образованный человек

basic knowledge – основные знания

at least – по крайней мере

well enough – достаточно хорошо

suitable – подходящий, соответствующий

views and opinions – точки зрения и мнения

on evidence – при наличии доказательств

to be desirable – быть желательным

significant – существенный

could be put down on ten sheets of paper – могли бы поместиться на десяти страницах
