“THE LANGUAGE OF COMPUTERS”
50 years ogo people hadn’t even heard of computers and today we cannot imagine life without them.
Computer technoligy is the fastest-growing industry in the world. The first computer was the size of a minibus and weighed a ton. Today its job can be done by a chip the size of a pen head. And the computer revolution is still going on. Very soon we’ll have computers that we’ll wear on our wrists or even in our glasses and earrings. Such wearable computers are being developed in the USA.
Japan’s biggest mobile-phone company has just realized its cleverest product so far, the i-mode, a mobile-phone allows you to surf the Internet as well as make calls. Soon they will be able to buy cinema tickets and manage their bank accounts.
The next generation of computers will be able to talk and even think for themselves. Of course, they will be still a lot simpler than human brains, but it will be a great step forward. Such computers will help to diagnose illness, find minerals, understand and control the world’s money markets, identify criminals and control space travels.
Computer revolution is changing our life and our language too. We are constantly making up new words or giving new meanings to old ones.
- What size was the first computer?
- What types of computers are being developed in the USA now?
- What are people using the phone for?
- What will the next generation of computers be able to do?
- How is the computer revolution changing our life?
VIII. Беседа о всемирной и локальной сети: (на русском и английском языках)
- Computers are widely used in high and secondary schools now. They help students to improve their reading and writing, arithmetics and geography. Students say that computers make learning fun and easy.
Б) Глобальная сеть WWW – World Wide Web (всемирная паутина)
Нужно выбрать качественный модем, чтобы не превратиться в World Wide Waiting (всемирное ожидание)
(Путь к файлу “Quick Chat”)

2) if you don’t understand me you stop me and ask me to repeat. Do you agree? //если вы не понимаете меня, то просите остановиться и повторить сказанное. Вы согласны?
Are you ready? We are beginning. //Вы готовы? Мы начинаем.
At the beginning we’ll remember (rewise) the Pascal program structure. Let’s rewise it together. There is one task. We’ll make together the program of the task.
//Для начала мы вспомним структуру программы на языке Паскаль. Давайте вспомним ее вместе. Вот задача. Мы вместе напишем программу для решения этой задачи.
Ex. 1. Find the area of a circle and the perimeter of a circle if you know a radius.
Do you understand the task?//вы понимаете условие задачи?
What is the input data in this task?// что является входными данными в задаче?
A radius.//радиус
What is the output data?//что является выходными данными?
The area of the circle and the perimeter of the circle. //площадь круга и длина окружности.
You remember the Pascal program structure is always strict: the program name, the description of variables, the special words, the read and write statement etc.// Вы помните, что структура программы на языке Паскаль всегда строгая: имя программы, описание переменных, служебные слова, ввод и вывод, и т.д.
Who want to go to the board to begin the program?//Кто хочет пойти к доске и начать программу?
Who want to continue? (Who can continue?)//Кто может (хочет) продолжить?
A probable dialogue://возможный диалог
What must be the first line of a Pascal program? //Что должно находиться в первой строе программы?
It’s the program name. //имя программы
What must be the second line of it? //что должно находиться во второй строке?
It’s the variable description. //описание переменных
Which type of variable do you know?//какие типы переменных ты знаешь?
There are 4 variable types we know: integer, real, char, string. //я знаю 4 типа переменных: целый, вещественный, строковый, символьный.
Can I use the russian letters in a program name or in a variable name?//могу я использовать русские буквы в имени программы или в названиях переменных?
Non, you can’t.//нет
What is the third line of a program?//какая третья строка программы?
It’s the special word Begin//это служебное слово begin
And after Begin?//а после begin?
The main block of the program.//основной блок программы
And after that?//а после него?
The End and the point.//End и точка.
Probable mistakes: wrong variable types, the semicolon is absent at the end of a line, wrong multiplication sign, the сomma instead of the point in the writing of the real number.
//Возможные ошибки: неверные типы переменных, отсутствует точка с зяпятой в конце строки программы, неверный знак умножения, запятая вместо точки при написании вещественных чисел и т.д.

Изучение нового материала - 8 минут.
Look at the formulae in the Pascal program and mathematical one. Compare them. What is the difference? (Answer - We use the different signs). Now we study new words and new symbols to write formulae in Pascal language. Listen to the new words and repeat it, please.
//Посмотрите на формулы в Паскале и математические формулы. Сравните их. В чем разница? (ответ – мы используем разные символы). Сейчас мы изучим новые слова и новые символы для записи формул на языке Паскаль. Прослушайте новые слова и повторите их, пожалуйста.
There are some special signs for write Pascal formulae.//существуют специальные символы для записи формул на Паскале.
+ addition//сложение
- subsruction//вычитание
/ division//деление
There are some Pascal functions://и вот несколько функций:
Sqr(x) – x 2 (square of x)
Sqrt(x) - x (square root of x)
Sin(x) – sin x (sine of x)
Cos(x) – cos x (cosine of x)
Abs(x) - |x| (absolute value of x)
Закрепление нового материала – 15 минут.
Now each of you go to the board, write a mathematical formula and Pascal one, then say it in English. //Сейчас каждый из вас по очереди идет к доске, записывает математическую формулу (из раздаточного материала) и ее же на Паскале, затем произносит по-английски.
Let’s resume our lesson. Did you like this lesson? Was the lesson very difficult? J’m sure you will remember the Pascal language forever What do you think?
//Подведем итоги урока. Вам понравился урок? Он был сложным? Я уверена, что вы запомните формулы языка Паскаль навсегда. Что вы думаете?
