2. Read and study.
A presentation is a formal talk to one or more people that "presents" ideas or information in a
clear, structured way. People are sometimes afraid of speaking in public, but if you follow a
few simple rules, giving a presentation is actually very easy.
All presentations have a common objective. People give presentations because they want to
communicate in order to:
inform
train
persuade
sell
A successful presentation is one of the most effective ways of communicating your message.
And because English is so widely used in international business, a working knowledge of the
vocabulary and techniques used in an English language presentation is a valuable asset.
3. Put the sentences concerning a presentation in the correct order.
a) Then we will look at how to "deliver" a presentation. ___
b) After that, we will consider what equipment to use.___
c) We will start by exploring the importance of preparation. _1_
d) Afterwards, you will be invited to take a test and ask questions. ___
e) Finally, we will conclude with a review of what we have covered. ___
f) After delivery, we will examine the language of presentations, before moving on to the
presentation itself. ___
4. Choose the correct words to complete the text: confident, control, feel , message, you.
With good preparation and planning you will be totally _______________ 1 and less nervous.
And your audience will _______________ 2 your confidence. Your audience, too, will be
confident. They will be confident in _______________ 3. And this will give you

6. Read and study the following useful information.
Notes
When you give your presentation, you should be - or appear to be - as spontaneous as
possible. You should not read your presentation! You should be so familiar with your subject
and with the information that you want to deliver that you do not need to read a text. Reading
a text is boring! Reading a text will make your audience go to sleep! So if you don't have a
text to read, how can you remember to say everything you need to say? With notes. You can
create your own system of notes. Some people make notes on small, A6 cards. Some people
write down just the title of each section of their talk. Some people write down keywords to
remind them. The notes will give you confidence, but because you will have prepared your
presentation fully, you may not even need them!
Rehearsal
Rehearsal is a vital part of preparation. You should leave time to practise your presentation
two or three times. This will have the following benefits:
- you will become more familiar with what you want to say
- you will identify weaknesses in your presentation
- you will be able to practise difficult pronunciations
- you will be able to check the time that your presentation takes and make any necessary
modifications
So prepare, prepare, prepare! Prepare everything: words, visual aids, timing, equipment.
Rehearse your presentation several times and time it. Is it the right length? Are you
completely familiar with all your illustrations? Are they in the right order? Do you know who
the audience is? How many people? How will you answer difficult questions? Do you know
the room? Are you confident about the equipment? When you have answered all these
questions, you will be a confident, enthusiastic presenter ready to communicate the subject of
your presentation to an eager audience.
11
7. Look at the equipment we use when making a presentation and write the suitable
missing English words we use to talk about it.
A. Easily your most important piece of equipment is...Y _ _ 1! Make sure you're in
full working order, and check your personal presentation carefully - if you don't, your
audience will!
B. The n _ _ _ _ _ _ _ c _ _ _ _ _ _ _ 2 is used to display text and graphics during
presentations. Basically, it can display anything that you put on your computer screen,
including entire presentations generated by presentation software. An excellent tool if used in
moderation, but not as an alternative to you—the speaker. It is often used in conjunction with
an overhead projector or other projector, which projects the image from the computer screen
onto the wall screen.
C. The o _ _ _ _ _ _ _ p _ _ _ _ _ _ _ _ 3
(OHP) displays o _ _ _ _ _ _ _ t _ _ _ _ _ _ _ _ _ _
_ _ _4 (OHTs or OHPTs). It has several advantages over the 35mm slide projector:
it can be used in daylight
the user can face the audience
the user can write or draw directly on the transparency while in use
12
D.The w _ _ _ _ _ _ _ _ _ 5 (more rarely blackboardorgreenboard) is a useful device for
spontaneous writing - as in brainstorming, for example. For prepared material, the OHP might
be more suitable.
E. The d _ _ _ _ _ 6 is used for cleaning the whiteboard. It is essential that the duster be clean
to start with. You may consider carrying your own duster just in case.
F. M _ _ _ _ _ _ 7 are used for writing on the whiteboard (delible - you can remove the ink) or
flipchart (indelible - you cannot remove the ink). They are usually available in blue, red, black
and green. Again, it's a good idea to carry a spare set of markers in case you are given some
used ones which do not write well.
G. The f _ _ _ _ _ _ _ _8 consists of several leaves of paper that you 'flip' or turn over. Some
people prefer the flipchart to the whiteboard, but its use is limited to smaller presentations.
H. The s _ _ _ _ p _ _ _ _ _ _ _ _ 10
- which must be used in a darkened room - adds a certain
drama. Slide projectors have mostly been overtaken by digital electronic media and are rare
today. Some slide projectors can be synchronised with audio for audio-visual (AV)
13
presentations. These projectors are typically used for larger presentations. The majority take
35mm slides or transparencies (as seen here), but projectors for 6x6cm slides are also
available.
I. Transparencies are projected by an overhead projector or a slide projector onto a s _ _ _ _ _
11 - in this case a folding screen which can be packed up and transported.
J. H _ _ _ _ _ _ _ 12
are any documents or samples that you 'hand out' or distribute to your
audience. Note that it is not usually a good idea to distribute handouts before your
presentation. The audience will read the handouts instead of listening to you.
Delivery is a vital aspect of all presentations. It is at least as important as content, especially
in a multi-cultural context.
8. Read paragraphs A-G which refer to the way in which you actually deliver, perform
or give your presentation. Choose from the box the correct words or expressions and
write them next to A-G.

Audience Rapport, Audience Reaction, Body Language, Cultural Considerations, Nerves,
Visual aids, Voice quality
A: _______________________________________________________________________
Most speakers are a little nervous at the beginning of a presentation. So it is normal if you are
nervous. The answer is to pay special attention to the beginning of your presentation. First
impressions count. This is the time when you establish a rapport with your audience. During
this time, try to speak slowly and calmly. You should perhaps learn your introduction by
heart. After a few moments, you will relax and gain confidence.
B: _________________________________________________________________________
You need to build a warm and friendly relationship with your audience. Enthusiasm is
contagious. If you are enthusiastic your audience will be enthusiastic too. And be careful to
establish eye contact with each member of your audience. Each person should feel that you
are speaking directly to him or her. This means that you must look at each person in turn - in
as natural a way as possible. This will also give you the opportunity to detect signs of
boredom, disinterest or even disagreement, allowing you to modify your presentation as
appropriate.
C: ________________________________________________________________________
What you do not say is at least as important as what you do say. Your body is speaking to
your audience even before you open your mouth. Your clothes, your walk, your glasses, your
haircut, your expression - it is from these that your audience forms its first impression as you
enter the room. Generally speaking, it is better to stand rather than sit when making a
presentation. Be aware of and avoid any repetitive and irritating gestures. Be aware, too, that
the movement of your body is one of your methods of control. When you move to or from the
whiteboard, for example, you can move fast or slowly, raising or reducing the dynamism
within the audience. You can stand very still while talking or you can stroll from side to side.
What effect do you think these two different approaches would have on an audience?
D: ________________________________________________________________________
Because English is so widely used around the world, it is quite possible that many members
of your audience will not be native English-speakers. In other words, they will not have an
Anglo-Saxon culture. Even within the Anglo-Saxon world, there are many differences in
culture. If we hypothetically imagine a German working for an Israeli company making a
presentation in English to a Japanese audience in Korea, we can see that there are even more
possibilities for cultural misunderstanding. You should try to learn about any particular
cultural matters that may affect your audience. This is one reason why preparation for your
presentation is so important. Cultural differences can also be seen in body language, which we
have just discussed. To a Latin from Southern France or Italy, a presenter who uses his hands
and arms when speaking may seem dynamic and friendly. To an Englishman, the same
presenter may seem unsure of his words and lacking in self-confidence.
E: _________________________________________________________________________
It is, of course, important that your audience be able to hear you clearly throughout your
presentation. Remember that if you turn away from your audience, for example towards the
whiteboard, you need to speak a little more loudly. In general, you should try to vary your
voice. Your voice will then be more interesting for your audience. You can vary your voice in
at least three ways:
15
speed: you can speak at normal speed, you can speak faster, you can speak more slowly - and you can stop
completely! You can pause. This is a very good technique for gaining your audience's attention.
intonation: you can change the pitch of your voice. You can speak in a high tone. You can speak in a low
tone.
volume: you can speak at normal volume, you can speak loudly and you can speak quietly. Lowering your
voice and speaking quietly can again attract your audience's interest.
The important point is not to speak in the same, flat, monotonous voice throughout your
presentation - this is the voice that hypnotists use to put their patients' into trance!
F: ________________________________________________________________________
Of all the information that enters our brains, the vast majority of it enters through the eyes.
80% of what your audience learn during your presentation is learned visually (what they see)
and only 20% is learned aurally (what they hear). The significance of this is obvious:
visual aids are an extremely effective means of communication
non-native English speakers need not worry so much about spoken English - they can rely more heavily
on visual aids
It is well worth spending time in the creation of good visual aids. But it is equally important
not to overload your audience's brains. Keep the information on each visual aid to a minimum
- and give your audience time to look at and absorb this information. Remember, your
audience have never seen these visual aids before. They need time to study and to
understandthem. Without understanding there is no communication.
G: ________________________________________________________________________
Remain calm and polite if you receive difficult or even hostile questions during your
presentation. If you receive particularly awkward questions, you might suggest that the
questioners ask their questions after your presentation.
9. Apart from photographs and drawings, some of the most useful visual aids are charts
and graphs, like the 3-dimensional ones shown below. Complete them.
P _ _ _ _ _ _ _ _
1 are circular in shape (like a pie).
16
B _ _ _ _ _ _ _ _
2 can be vertical (as here) or horizontal.
G _ _ _ _ _
3 can rise and fall.
10. Read and study.
Most presentations are divided into 3 main parts (+ questions):
1. INTRODUCTION
2. BODY Questions)
3. CONCLUSION
Questions
As a general rule in communication, repetition is valuable. In presentations, there is a golden
rule about repetition:
1. Say what you are going to say...
2. say it...
3. then say what you have just said.
In other words, use the three parts of your presentation to reinforce your message. In the
introduction, you tell your audience what your message is going to be. In the body, you tell
your audience your real message. In the conclusion, you summarize what your message was.
We will now consider each of these parts in more detail.
The introduction is a very important - perhaps the most important - part of your presentation.
This is the first impression that your audience have of you. You should concentrate on getting
your introduction right. You should use the introduction to:
1. welcome your audience
17
2. introduce your subject
3. outline the structure of your presentation
4. give instructions about questions
The body is the 'real' presentation. If the introduction was well prepared and delivered, you
will now be 'in control'. You will be relaxed and confident. The body should be well
structured, divided up logically, with plenty of carefully spaced visuals.
Remember these key points while delivering the body of your presentation:
do not hurry
be enthusiastic
give time on visuals
maintain eye contact
modulate your voice
look friendly
keep to your structure
use your notes
signpost throughout
remain polite when dealing with difficult questions
Use the conclusion to:
1. Sum up
2. (Give recommendations if appropriate)
3. Thank your audience
4. Invite questions
11. The following table shows examples of language for each of these functions. You may
need to modify the language as appropriate. Read possible language and complete the
table with the suitable functions.

Questions
Questions are a good opportunity for you to interact with your audience. It may be helpful for
you to try to predict what questions will be asked so that you can prepare your response in
advance. You may wish to accept questions at any time during your presentation, or to keep a
time for questions after your presentation. Normally, it's your decision, and you should make
it clear during the introduction. Be polite with all questioners, even if they ask difficult
questions. They are showing interest in what you have to say and they deserve attention.
Sometimes you can reformulate a question. Or answer the question with another question. Or
even ask for comment from the rest of the audience.

1Listening script: What is greenhouse effect?
Our climate is changing and temperatures in general are increasing on the planet. Sea levels are rising and the ice
is melting at the North and South Poles. One reason for this is the greenhouse effect. But what is the greenhouse
effect? A greenhouse is normally something useful, it helps us grow things like tomatoes out of season. That's
because it's nice and warm inside a greenhouse. The sun light enters and visible light penetrates the glass. This is
partly absorbed by the plants in the soil and partly reflected on the outside as invisible heat radiation. As a result
temperatures rise inside the greenhouse. The planet Earth obtains warmth in a similar fashion which is fortunate
because otherwise we could not survive. Without the natural greenhouse effect temperatures on our planet would
be around - 18 degrees Celsius and not the average 15 degrees Celsius above freezing. Sunlight penetrates the
gas layer of the atmosphere, it's partly absorbed and partly reflected just like in a greenhouse. Small particles in
the air ensure that a percentage of the reflected radiation is sent back to earth. However, humans caused a lot of
pollution by producing large amounts of carbon dioxide, methane and nitrous oxide. The small particles increase
in number and the result is just like a greenhouse where the glass is too thick. So an increased amount of
radiation is sent back to earth and the heat is unable to escape causing temperatures to rise constantly on our
planet.

READING
1. Read the text on the Ozone Layer. Decide whether each of the following sentences is
true or false. If the sentence is false, change the sentence so that it is true.
37
During the past years, the ozone layer, which protects the earth from the harmful ultraviolet
radiation of the sun, has started to disappear. In fact, scientists have found a hole in the ozone
layer over Antarctica. Scientists believe that CFC´s (chlorofluorcarbons), which are chemicals
used in air conditioners, refrigerators, and aerosol cans, have caused the hole in the ozone
layer. The hole in the ozone layer is likely to lead to more skin cancer and other serious health
problems in the future. Scientists and engineers need to develop alternatives to CFC‟s in
order to protect the ozone layer.
1. The ozone layer protects the earth from carbon dioxide. __F__

WASTE AND RECYCLING
2. Read the text on Waste and Recycling. For the words and phrases typed in italics find
the Slovak equivalents.
For most of us, waste is the bags of household rubbish1that leave our households
2 every week.
We know that it is “put somewhere” – but few have actually seen a landfill site3, a
38
wasteincineration plant4, or a recycling centre, and most of us do not give it much more
interest.
Three different kinds of wastes exist today: municipal solid waste5(MSW), hazardous waste
6,
and commercial/industrial waste7. Municipal solid waste consists of many different materials:
some burn, some do not, some are readily recyclable8, some are not. Paper, for instance, is the
largest component of MSW. Additional millions tons are attributed to glass, various metals,
plastics and miscellaneous waste9. Chemical, metal, and furniture manufacturing processes
are some examples of processes that create hazardous waste. Products, such as paints,
cleaners, oils, batteries, and pesticides contain hazardous ingredients10
and require special
care when we dispose of them. Improper disposal11
of these wastes can pollute the
environment that consequently can be harmful to human health. Experts estimate that 50
percent of all these waste materials could be recycled12
each year. Currently, however, only
about 10 percent is recycled13
. One reason is that the public does not pay much attention to
the garbage14
crisis. Many citizens have an “out of sight, out of mind”attitude15
about where
the trash16
goes once it leaves the curb17
. To preserve the environment, the public needs to be
educated to a new version of the “ three R´s” – reduce, reuse, and recycle18
.

THE WORLD WIDE WEB
1. Read the text and then answer the questions.
The Internet is a worldwide telecommunications system that provides connectivity for
millions of other, smaller networks; therefore, the Internet is often referred to as a network of
networks. It allows computer users to communicate with each other across distance and
computer platforms.
The Internet is often confused with the World Wide Web. The misperception is that these
two terms are synonymous. The Internet is the collection of the many different systems and
protocols. The World Wide Web, developed in 1989, is actually one of those different
protocols. As the name implies, it allows resources to be linked with great ease in an almost
seamlessfashion.

computers must follow to exchange messages was developed. The two most important
protocols allowing computers to transmit data on the Internet are
_______________________________________________a
(TCP)and
______________________________________ b
(IP). With these protocols, virtually
all computers can communicate with each other. For instance, if a user is running
Windows on a PC, he or she can communicate with iPhones.
2. An Internet address has four fields with numbers that are separated by periods or dots.
This type of address is known as an IP address. Rather than have the user remember
long strings of numbers, the ______________________________ (DNS) was
developed to translate the numerical addresses into words. For example, the address
fcit.usf.edu is really 131.247.120.10.
3. Addresses for web sites are called _______________________________ (URLs).
Most of them begin with http (HyperText Transfer Protocol), followed by a colon and
two slashes. For example, the URL for the Florida Center for Instructional Technology
is http://fcit.usf.edu/ .

CONVENTIONAL AND UNCONVENTIONAL MACHINING PROCESSES
READING
1. Read the text on Conventional and Unconventional Machining Processes and answer
each of the following questions.
Conventional and Unconventional Machining Processes
Machining is the broad term used to describe removal of material from a workpiece. It is
important to view machining as a system consisting of the workpiece, the tool and the
machine.
Traditional machining processes (also called conventional) – drilling, turning, milling and
grinding remove material by chip formation, abrasion, or microchipping.
These are, however, situations, where these processes are not satisfactory, economical, or
even possible, for the following reasons:
- the hardness and strength of the material is very high
- the material is very brittle
These requirements led to the development of chemical, electrical, laser, and other means of
material removal. Advanced machining processes (also called non-traditional or
unconventional) – chemical machining, electro chemical machining, laser beam machining,
water jet machining, abrasive water jet machining, hydroforming, plasma cutting, electrical
discharge machining, etc. have unique capabilities. They involve chemical, electrochemical,
electrical, or laser sources of energy. The mechanical properties of the workpiece material are
not significant because these processes rely on mechanisms that do not involve the strength,
hardness, ductility, or toughness of the material, rather they involve physical, chemical, and
electrical properties.

A. ______________ shapes can be achieved through synchronizing the movement of the
workpiece, tool and tool feed.
B. ______________ is the machining of a surface using a cutter which has a number of
teeth. The surface produced may be plain or, by using additional equipment or special
cutters, formed surfaces may be produced.
C. ______________ is used to remove material from the inside of a workpiece.
67
D. ______________ machine is used to machine surfaces. It can cut curves, angles and
many other shapes. It is a popular machine in a workshop because its movement is
very simple although it can produce a variety of work.
E. ______________ is the machining operation that produces cylindrical parts. In its
basic form, it can be defined as the machining of an external surface: with the
workpiece rotating, with a single-point cutting tool, and with the cutting tool feeding
parallel to the axis of the workpiece and at a distance that will remove the outer
surface of the work.
F. ______________ is a material removal and surface generation process used to shape
and finish components made of metals and other materials.
4. Read the following descriptions of the advanced machining processes. Identify the
processes and the key vocabulary of each process.
A ___________________________________________________________________
An electrical spark1 is created between an electrode and a workpiece
2. This electric spark
produces intense heat with temperatures reaching 8000 to 12000 degrees Celsius. It melts3
almost anything. The spark is very carefully controlled4 and localized so that it only affects
the surface5 of the material. The process usually does not affect the heat treat below the
surface. The spark always takes place in the dielectric of deionized water. The conductivity6
68
of the water is carefully controlled making an excellent environment for the process. The
water acts as a coolant7 and flushes
8 away the eroded metal particles

B ______________________________________________________________
This process is a mechanical energy basednon-traditional machining process used to cut1 and
machine2 soft and non-metallic materials. It involves the use of high velocity water jet
3 to
smoothly cut a soft workpiece.
High velocity water jet is allowed to strike a given workpiece. During this process, its kinetic
energy is converted to pressure energy. This induces a stress on the workpiece. When this
induced stress is high enough, unwanted particles4 of the workpiece are automatically
removed.

LISTENING
1. Listen to the text about the classification of engineering materials and fill in the
blanks to make the sentences complete.
In order to select the best material for a job, engineers must know the types of materials
available and the properties of these materials. There are two basic types of materials used in
engineering: metals and non-metals. Some materials, however, are on the border between
metals and non-metals. These materials are sometimes called metalloids.
Metals
Of the 92 natural elements found on Earth, about 70 are _______________ 1
and about 40 of
these are used commercially. Metals can be divided into ferrous metals and non-ferrous
metals. Ferrous metals contain iron, while _______________ 2
metals do not.
Cast, iron and steel, which are mixtures of iron and carbon, are the two most important
_______________ 3
metals used in engineering. Cast iron, which includes grey cast iron,
white cast iron, and malleable ________________ 4, contains more carbon than steel. Cast
iron is also harder and less malleable than steel.
The most common non-ferrous metals used in _______________ 5 are aluminium, copper,
bronze, and brass. Bronze and brass are alloys, which are metals that are formed by the union
or mixture of two or more elements.
73
Non-metals
_______________ 6
can be classified into plastics and ceramics. Plastics generally can be
machined like metals, while ceramics cannot be machined. _______________ 7
can be
divided into _______________ 8
and thermosets. Thermoplastics can be shaped and reshaped
by heat, while _______________ 9
cannot be reshaped by heat because they undergo chemical
changes as they harden. _______________ 10
are often used by engineers when they need a
material that can withstand high temperature.

READING
1. Read this article about nanotechnology and circle T (true) or F (false).
All manufactured products are made from atoms. The properties of these products
depend on how those atoms are arranged. If we rearrange or move around the atoms
in coal, we can make diamonds. If we rearrange the atoms in sand (and add a few
more elements), we can make computer chips. If werearrange the atoms in dirt,
water, and air, we can make potatoes.
Today´s manufacturing methods are very basic and simple at the molecular level. Casting,
grinding, and milling move or cut away millions of atoms. It´s like trying to make things out
of LEGO bricks with boxing gloves on your hands. Yes, you can push the LEGO bricks into
big heaps and pile them up, but you can´t put them together the way you´d like.
In the future, nanotechnology will let us take off
those boxing gloves. We´ll be able to snap together
the basic building blocks of nature easily,
inexpensively, and in lots of different ways. This
will be important if we want to continue developing
faster, smaller, and more powerful computer
82
hardware. It will also let us produce completely new products that are cleaner, stronger,
lighter, and more accurate.

What software is involved in CNC (Computer Numerical Control)? There are primarily
three parts:
CAD (Computer Aided Design) software is where you design your parts to be routed, lathed,
milled, or cut.
CAM (Computer Aided Manufacturing) software converts your CAD drawings into G-
code, which is the programming language that the CNC control software understands.
The CNC control software then reads the G-code and turns it into motion to drive your
machine.

CAM utilizes the part geometry defined by the CAD drawing. That geometry is imported into the CAM software
which allows the engineer to select cutting paths and other parameters for manufacturing a specific part. CAM
uses databases that are specific to the material, tools and the work centre to be used in the actual machining
process. The program identifies the manufacturing process information utilizing the CAM software such
as feeds, speeds and depth of cut. This information is run through the post processor which translates information
into a CNC program that the work centre can utilize directly. The CAM system can also simulate a production
cycle of the part which includes a visual representation of the machine, tooling and workpiece motion. The
software can provide an estimated cycle time that can be used for quoting. It will also alert the engineer of any
tool collisions, constraints or interference that may occur.

notices and obey health and safety rules. If you don´t you could get hurt, and you might put
other people in danger.
Imperative statements that use the word must tell us to do things in a safe way.
examples:

You must stay outside until it is safe to go back in.
Imperative statements use must not or do not to warn people about danger.
They remind you not to do things that are risky, or unsafe.
examples:
You must not use the lift during a fire!
Do not block the fire exit!
Red warning signs warn you about things you can´t do.
Blue warning signsremind you of things you need to do to stay safe.
