Unit 2. Computers for the disabled.
Vocabulary. Disabled – человек с ограниченными возможностями, инвалид Leading role - главная роль To require – требовать, приказывать Blind – слепой Deaf - глухой Motor-disabled – с ограниченными двигательными возможностями Dull sight – слабое зрение Blinking – мерцание, моргание Muscle movements – движение мускул Breath movements – дыхательные движения Computers have taken a leading role in our society and most jobs require access to computers and the internet. There are many people who are blind, deaf or motor-disabled and new technology allows them to use computers, do their jobs in the office, learn at school, communicate with other people. Most blind users have computers adapted with technologies such as Braille, screen magnifiers, speech synthesis. There are Braille keyboards which have Braille lettering allowing identify each key. For people with dull sight there is a screen magnifier which can enlarge text by up to 16 times. A speech synthesis system reads aloud the work on computers. Deaf computer users can overcome many difficulties using visual alerts, electronic notetakers and textphones. Visual alerts are indicators with a blinking menu which appear when a user receive a new mail. Electronic notetakers use software to type a summary of a meeting. Textphones allow the deaf to type and read phone conversations. Deaf people also can communicate via SMS and instant messaging. Disabled people who can’t type on a standard keyboard use expanded or ergonomic keyboards, on-screen keyboards, adaptive switches and voice recognition systems. For example, in an eyegaze system the keys on the virtual keyboard are activated by the user’s eyes when they pause on a key for two or three seconds. Switches come in many shapes and sizes. They are operated by muscle movements or breath movements or breath control. There’s also voice recognition which allows the computer to interpret human speech transforming the words into digitized text or instructions.
Answer the questions according to the text: 1) What kinds of disabled people can you call? 2) Why do they need special possibilities of the computers? 3) What new technologies for disabled people do you know? 4) What can people do with the help of computers? 5) What can be found around us for disabled people?
Exercises: 1) Match the Russian and English equivalents. Make up the sentences with these words and word combinations:
2) Read the definitions and write the suitable word: a) software that enlarges text and images on the screen, making the content more readable for users with low vision. b) technology that allows computers to recognize text input into a system with a scanner. c) a system of writing devised for blind people, in which combinations of raised dots representing letters and numbers can be identified by touch. d) a phone with a small screen and a keyboard that transcribes spoken voice as a text, it’s used by people with hearing or speech difficulties. e) a system activated by the user’s eye movements.
3) Choose ing- form or infinitive after the verbs: We started ………. (to retell) the text a half of an hour ago. New technologies allow disabled people……….. (to use) and work on computers. They finished…….. (to discuss) the project an hour and a half ago. They decided….. (to enlarge) their business in Asia and Russia. Our government want……… (to take care) of disabled people more but they are more interested in ………….(to give) them different jobs by companies. 4) Translate the following sentences using the appropriate pronouns: Люди с ограниченными возможностями не могут выполнять некоторые функции, которые необходимы для жизни. Поэтому для них разработаны специальные компьютеры, где находятся устройства, позволяющие им использовать и работать на компьютере. Люди с ограниченными возможностями знают, когда и как использовать Мы должны понимать, почему они нуждаются в нашей помощи и поддержке государства.

Unit 3. What is a computer?
Vocabulary. To accept – принимать, допускать To process - обрабатывать To consist of – состоять из Software – программное обеспечение Hardware – техническое обеспечение The central processing unit (CPU) – центральный процессор ЦП Main memory – оперативное, основное запоминающее устройство ЗУ Peripherals - внешний, дополнительные устройства Permanent storage – постоянное запоминающее устройство ЗУ Attached to – прикрепленный, прилагаемый Port – порт, многозарядный вход или выход в устройстве
A computer is an electronic machine which can accept data in certain form, process the data and give the results of the processing. First, data directs into computer’s memory, then the computer performs a set of instructions and processes the data when the computer’s programs are run. Finally, we can see the results on the screen or in printed form. A computer system consists of two parts: hardware and software. Software is a set of instructions or programs which tells the computer what to do. Hardware is an electronic or mechanical part you can see or touch. There are three basic hardware sections: the central processing unit (CPU), main memory and peripherals. The main part of computer is the central processing unit. Its function is to execute program instructions and coordinate everything, it’s the “brain” of the computer. The main memory, it’s a collection of RAM chips, holds the instructions and data. Peripherals are the physical units attached to the computer which include storage devices and input/output devices. Storage devices for example hard drivers, DVD drivers, flash drivers provide a permanent storage of data and programs. We use disk drivers to read and write data on disks. Input devices enable data to go into computer’s memory. The most common input devices are the mouse and the keyboard. Output devices extract the finished product from the system and show or print the results. On the rear panel of the computer there are several ports for a modem, a digital camera, a scanner etc. They allow communication between the computer and the devices. On the front panel of modern desktop PCs there are USB ports and memory card readers. Answer the questions according to the text: 1) What parts does a computer consist of? 2) What are three sections of hardware you know? 3) What and why is the brain of computer? 4) What peripherals can you call? 5) How does a computer operate? Exercises: 1) Match the Russian and English equivalents. Make up the sentences with these words and word combinations:
2) Read the definitions and write the suitable word: a) The physical units which make up a computer system. b) The set of program instructions that tell the computer what to do. c) The processor chip that performs the basic operations of a computer; its basic components are the control unit, the arithmetic logic unit and the registers. d) The units connected to the computer classified into three types. e) There are two types of this section which holds the instructions and data currently being processed.
3) Fill in the prepositions: The computer performs a set… instructions. Storage devices provide a permanent storage … data and programs. We use disk drivers to read and write data…. disks. Input devices enable data to go …. computer’s memory. The most common input devices used all…..the world are the mouse and the keyboard. Output devices extract the finished product …. the system and show information ….the screen or print the results …..the printer. …. the rear panel … the computer there are several ports …. a modem, a digital camera, a scanner etc. They allow communication ….. the computer and the devices. …. the front panel … modern desktop PCs there are USB ports and memory card readers. You can extract data ….computer very quickly ……flashcard.
4) Are the sentences true or false? Correct the sentences: The main part of computer is the peripherals. The function of the central processing unit is to execute program instructions and coordinate them. The disk drivers enable data to go into computer’s memory. On the rear panel of the computer there is only one port. The main memory is a collection of RAM chips.
