Trang 71 Computers can help students perform mathematical operations and solve difficult questions.They can be used to teach courses such as computer-aided design, language learning,
programming, mathematics, etc
PCs (personal computers) are also used for administrative purposes: for example, schools usedatabases and word processors to keep records of students, teachers, and materials
2 Race organizers and journalists rely on computers to provide them with the current positions of
riders, and teams in both the particular stages of the race, and in the overall competition
Workstations in the race buses provide the timing system, and give up-to-the-minute timinginformation to TV stations In the press room, several PCs give real-time information on the state
of the race Computer databases are also used in the drug- detecting tests for competitors
3 Computers store information about the amount of money held by each client, and enable staff
to access large databases, and to carry out financial transactions at high speed They also controlthe automatic cash dispensers which, by the use of a personal coded card, dispense money toclients
4 Airline pilots use computers to help them control the plane For example, monitors display data
about fuel consumption, and weather conditions
In airport control towers, computers are used to manage radar systems, and regulate air traffic
On the ground, airlines are connected to travel agencies by computer Travel agents use
computers to find out about the availability of flights, prices, times, stopovers, and many otherdetails

IV Language work: The passive
Look at the active and passive sentences below and answer the questions
Trang 91 Find the objects of the active sentences Are they: (1) before the verb; (2) after the verb?
2 Find the same words in the passive sentences? Are they: (1) before the verb; (2) after theverb?
3 The object of the active sentences becomes the subject of a passive sentence True or false?
4 Look at the first word of the verb in the passive sentences Is it a form of: (1) be; (2) do; (3)
have.
5 Look at the second word of the verb in the passive sentences: Is it in: (1) the infinitive; (2) thepast simple; (3) the past participle?
6 Passive verbs consists of a form of be plus a past participle True or false?
7 Read all the sentences Does somebody appear in the active or the passive sentences?
8 Do we know who somebody is?
9 We can use the passive to talk about actions when we don’t know who performed them True
Facts and processes
When we write or talk about facts or processes that occur regularly, we use the present passive.Examples:
Active
Trang 101 We sell computers (simple present)
2 Babbage invented 'The Analytical Engine' (simple past)
Passive
1 Computers are sold (simple present)
2 ‘The Analytical Engine' was invented in 1830 (simple past)
Events
When we write or talk about past events, we use the past passive Let us look at some examples Examples:
1 COBOL was first introduced in 1959
2 Microsoft was founded on the basis of the development of MS/DOS

Programs and data mechanical and electronic equipment
Physical units The “brain” of C B Read the text and check your answer. What is a computer? Computers are electronic machines which can accept data in a certain form, process the data and give the results of the processing in a specified format as information Three basic steps are involved in the process First, data is fed into the computer's memory Then, when the program is run, the computer performs a set of instructions and processes the data Finally, we can see the results (the output) Information in the form of data and programs is known as software, and the electronic and mechanical parts that make up a computer system are called hardware A standard computer system consists of three main sections: the central processing unit (CPU), the main memory, and the peripherals Computer system Main memory
Storage devices Input/ Output devices ROM M
Trang 14
Perhaps the most influential component is the central processing unit Its function is to
execute program instructions and coordinate the activities of all the other units In a way, it is the
'brain' of the computer The main memory holds the instructions and data which are currently being processed by the CPU The peripherals are the physical units attached to the computer.
They include storage devices and input/output devices
Storage devices (floppy, hard or optical disks) provide a permanent storage of both data and programs Disk drives are used to handle one or more floppy disks Input devices enable data to go into the computer's memory The most common input devices are the mouse and the keyboard Output devices enable us to extract the finished product from the system For example, the computer shows the output on the monitor or prints the results onto paper by means
a software b peripheral devices c monitor d floppy disk
e hardware f input g port h output i CPU

8 Small device used to store information Same as “diskette”
9 Any socket or channel in a computer system into which an input/output device may beconnected
III Speaking
Read and guess
Read these slogans or quotations, and say what computer element they refer to
1 a 'Point and click here for power'
b 'Obeys every impulse as if it were an extension of your hand'
2 a 'Displays your ideas with perfect brilliance'
b 'See the difference -sharp images and a fantastic range of colors'
3 a 'I love this drive It's quiet and fast'
b 'With this, it's easy to back up your data before it's too late'
4 a 'Power and speed on the inside'
b 'Let your computer's brain do the work'
5 a ' a big impact on the production of text and graphics'
b 'Your choice: a laser powerhouse'
IV Language work: Contextual reference
Transitional markers are words used to link ideas together so that the text is easier to read
When pronouns such as it, they, them, I, he, she, which, who, whose, that, such, one, and demonstrative adjectives such as this, that, these, and those are used as transitional markers They
refer to a word, or words mentioned earlier in the sentence or paragraph Their function is to takeyour thoughts back to something that has already been mentioned Other words which are often
used to refer backwards are the former, the latter, the first, second, etc., the last.
Sample paragraph:
Trang 16A computer like any other machine is used because It does certain jobs better and moreefficiently than humans It can receive more information and process it faster than any human.The speed at which a computer works means it can replace weeks or even months of pencil-and-paper work Therefore computers are used when the time saved offsets their cost, which isone of the many reasons they are used so much in business, industry and research
Exercise: Using the sample paragraph as a model, draw a circle around the word, or words, that the words in rectangles refer to Then, join the and the 1 with arrows.
Modern accounting firms use spreadsheet software to do complicated calculations Theycan provide their clients with an up-to-date report whenever it is needed This software hasmany functions and can be integrated with other software The spreadsheet's basic component is acell This may contain a formula which performs a mathematical operation It could also contain
a label or data The former describes the information on the worksheet The latter is theinformation itself
The worksheet is the basic work area of a spreadsheet program It is made up of cellsarranged in rows and columns The number of these varies depending on the software you areusing You can change the width and format of cells Such parameters are usually quite easy tochange with just a few keystrokes

B Read the text below and do exercises.
What is inside a microcomputer ?
The nerve centre of a microcomputer is the central processing unit or CPU This unit is
built into a single microprocessor chip -an integrated circuit -which executes program
instructions and supervises the computer's overall operation The unit consists of three mainparts:
1 -The control unit, which examines the instructions in the user's program, interprets each
instruction and causes the circuits and the rest of the components disk drives, monitor, etc -to beactivated to execute the functions specified;
2 -The arithmetic logic unit (ALU), which performs mathematical calculations (+, -, etc.) and
logical operations (and, or, etc);
3- The registers, which are high-speed units of memory used to store and control information.
One of these registers is the program counter (PC) which keeps track of the next instruction to beperformed in the main memory Another is the instruction register (IR) which holds the
instruction that is currently being executed.
Trang 20One area where microprocessors
differ is in amount of data the number of bits
- they can work with at a time There are 8,
32, and 64-bit processors The computer's
internal architecture is evolving so quickly
that the new 64-bit processors are able to
address 4 billion times more information
than a 32-bit system (see Fig.1)
The programs and data which pass through
the central processor must be loaded into the
main memory (also called the internal
memory ) in order to be processed.
Thus, when the user runs an
application, the microprocessor looks for it
on secondary storage devices (disks) and
transfers a copy of the application into the
RAM area RAM (random access memory)
is temporary, i.e its information is lost when
the computer is turned off However, theROM section (read only memory) ispermanent and contains instructions needed
by the processor
Most of today's computers have
internal expansion slots that allow users to
install adapters or expansion boards Popularadapters include high-resolution graphicsboards, memory expansion boards, andinternal modems
The power and performance of acomputer is partly determined by the speed
of its microprocessor A clock provides
pulses at fixed intervals to measure andsynchronize circuits and units The clockspeed is measured in MHz (megahertz) andrefers to the frequency at which
pulses are emitted For example, a CPUrunning at 500 MHz (500 million cycles persecond) is likely to provide a very fastprocessing rate and will enable the computer
to handle the most demanding applications
The new generation of
processors
Figure 1 shows the 600 MHz
Alpha microprocessor from
Digital, with a 64-bit RISC
Trang 21Task 1: Decide sentences 1 to 8 whether the sentences are true (T) or false (F), and rewrite the false ones to make them true.
1 The CPU directs and coordinates the activities taking place within the computer system
2 The arithmetic logic unit performs calculations on the data
3 32-bit processors can handle more information than 64-bit processors
4 A chip is an electronic device composed of silicon elements containing a set of integratedcircuits
5 RAM, ROM, and secondary storage are the components of the main memory
6 Information cannot be processed by the microprocessor if it is not loaded into the mainmemory
7 'Permanent' storage of information is provided by RAM (random access memory)
8 The speed of the microprocessor is measured in megahertz One MHz is equivalent to onemillion cycles per second
Task 2: Contextual reference What do the words in “bold” and “italics” print refer to?
1 … which executes program instructions and supervises….
2 the instruction that is currently being executed.
3 ……the amount of data - the number of bits - they can work with at a time.
4 the microprocessor looks for it on .
5 its information is lost when the computer is turned off.
6 expansion slots that allow users to install adapters or expansion boards.
III Language work: Relative clauses
Study these sentences:
1 The microprocessor is a chip
2 The chip processes the information provided by the software
Both these sentences refer to chip We can link them by making sentence 2 a relative clause:
The microprocessor is a chip which processes the information provided by the software The relative clause is in bold italics Note that' The chip' in sentence 2 becomes 'which'.
Study these other pairs of sentences and note how they are linked.
