The age between 14 & 17 is considered to be one of
the best periods in people's life. Grown-ups remember
it with excitement & tenderness. But most teens
wouldn't agree with this opinion if they were asked.
They're sure and that's quite true that they are
overwhelmed with different problems. These
problems're quite serious and they can't be considered
trifles. Teenagers have psycological problems which
can be explained by their psycological instability.This
is the reason of their strange & sometimes agressive
behavior. Their agression can be aimed at their friends,
teachers, parents and people around them. If these
problems aren't solved & regulated by experienced
specialists, psycologists, teachers it can lead to far
more serious problems. Drinking and taking drugs have
become the most actual problems of the modern
society. As for drinking, teenagers don't realize the
harm it does to their health, they just don't want it to
the privilegeof grown-ups but unlikegrown-ups they are
notable to to drink responsibly. Government surveys on
all aspects of drinking have found that about 40
percent of teenagers're attracted by bright & impressive
advertisments of alcohol. They really believe that
certain drinks will make them look like they're
accepted. So, we can say that the low level of self-
appraisal is the main reason of drinking and drug
problem. Teenagers're greatly influenced by social
problems such as unemployment, disfunctional families
& the stress of getting into new college. They don't
know how to cope with the problems which do not
depend on them. They're badly prepared for their
solution mentally, spiritually & even physically. If
theyfail, they can be driven to despair & won't find the
way out if not helped by their families, school and
some other representatives of society. In fact,
teenagers have got a lot of work. They're busywith
their studies, household chores, some of them have a
paid job. But there's no time for fun and they want to
be entertained at least sometimes. This excessive work
leads to an inner conflict which's usually expressed in
the form of an open, direct protest against the world of
grown-ups. The next step's the conflict with parents
which's very difficult to solve. On the other hand, most
teens don't know how to organize their free time for
raising their cultural level, enriching their knowledge &
improving their physical forms.
