Watching TV
Many people have already forgotten what the world was like
before television. Several generations of children have grown up
with a TV-set as a baby-sitter, teacher and a companion. It has
become an integral part of our lives. No medium (CMU) can
compare with television as a means of information,
entertainment and education.
1. Work in teams. Prove that television is a means of
information, entertainment and education. Think of the
best arguments. You may use the following questions:
a. Do you watch TV regularly or occasionally?
b. What about other members of your family?
c. Do you watch the same programs?
d. Are there any programs that you particularly like? What
are they?
e. Do you regularly watch news programs?
f. Do you watch programs on the educational channel?
g. Did the TV stop you from reading or did it stimulate you to
read more?
h. If you were a program caster what programs would you
choose?
The team that gives the most convincing arguments wins.

2. Let's imagine a tour of our solar system. We begin our jour-
ney from the sun, but of course we could never live there - the
temperature on the surface is 6000°C! The first planet we see
is Mercury. It is strange because the same side always faces
the Sun, so one Half of the planet is very hot and the other side
is extremely cold. It orbits the Sun once every 88 days. The
