1).
Diet
When
people talk about “going on a diet”, they usually mean they are trying to limit
the amount and type of food that they eat, in order to become thinner.
Nevertheless, diet actually refers to sensible nutrition for a variety of
purposes – to gain, as well as to lose weight. A diet can also be done as part
of medicinal procedures, for example, too counteract summer heat or winter cold
and treat someone who suffers from stomach troubles.
2).
Robots
Robot
comes from the Czech word ‘robota’ which means ‘work’ or ‘labor’. A robot is a
machine that does the work of a human being.
Robots
are used to perform repetitive tasks which require precision. For example, they
are used to manufacture cars. In the future, robots might be used perform
surgical operations on people. A computer could direct the prosedure with great
precision while human surgeons could check the progress of the operation on
large video screens.
Robots
may soon become useful for doing unpopular household chores like sweeping and
mopping. Robotd could also be used to do jobs which are unsafe for humans, like
cleaning the site of a nuclear accident.
3).
The Flying Doctors
There
are some countries in the world with vast, desolate areas which it is hard for
any doctors to reach a patient in need of urgent medical help. In Kenya, for
example, a prson could be near to death because of a snakebite whilst crossing
the Kenya National Park. The distance is so vast that the victim would probably
not be alive by the time he reached hospita. And so, the Fliying Doctors
service would come into being. The servise is called by radio – a person just
calls, says what has happened and where the patient is, and the doctors flies
in as soon as possible
Countries
such as Australia and Canada make widespread use of the Flying Doctors Services
to provide medical cover to those remote aeas where conventional surface
transprt might take many more hours or even days. Although fixed wing airplanes
are faster, helicopters may be used because of their ability to land in very
confined spaces like forest clearings or gospital roofs.

Sleep
Sleep
is a temporary lapse of consciousness. During sleep, our central nervous
system, breath, heart-bet, and muscle-tone are slowing down.
Human
sleep duration varies enormously. Babies sleep 18-20 hours a day, young
children 12-14 hours, adults 7-9 hours, and older people 5-7 hours.
Now,
some people suffer from insomnia. These people cannot sleep easily. Insomnia is
not an illness. It is a symptom of a sleeping disorder which can be caused by
anxiety, depression, and exitement. It cannot be cured without getting rid of
the problems which which cause it. But temporary, insomnia can be overcome by
drinking chamomile tea.

Javelin-throwing
Javelin
is a long stick with a pointed end. The aim of javelin-throwing is to throw it
at a great distance.
Javelin-throwing
is a sport which has benefited from modern technology. Earlier, javelins were
made of heavy wood which made them vibrate in flight. In the 1950s, athletes
began to use steel javelins. Today, most javelins are made of steel and a
lighter metal called alumunium.
Many
factors effect the distance to which the athlete can throw the javelin. Among
these are the speed and height at which it leaves the hand, the angle at which
it is thrown, and its flight path.
Modernn
javelins are ‘distance-rated’. This means that different javelins are made to
be thrown at different distances. So, you can use a javelin that is designed to
travel roughly about the distance you expect to throw it.
