1. FINDING THE MAIN
IDEA

2. The sun must have a supply of energy if
it is to exist. The Milky Way must have a supply
of energy if it and each of its parts is to keep
working. The universe must have a supply of
energy or it would cease to exist as it is today.
Energy is necessary in the universe, and this is
why the universe is called an energy system.

3. In the beginning, God created
the earth, the sky and all the
heavenly planets. He also created
the plants on land, the birds in the
air, and the fish in the water after
He separated the land from the
water. Finally, he created man to
have dominion over everything He
created.

4. Volcanoes change the
surface of the earth. Ashes and
lava may pile up layer after layer,
until a mountain is built.
Sometimes a volcano on the
ocean floor will rise above the
sea to form an island.

5. You won’t find this clock in a
corner or in a room. No one
knows where it really is. Some
scientists think there is a kind
of clock inside you and me and
all other animals. This clock
doesn’t even tick or even tack.
Your body knows when to go
to sleep. The birds of the air
know when to fly home to their
nests. Finally, bears know
when to wake up in spring
after their long winter sleep.

6. Somewhere in the darkest corner of
your closet, you may find something
very useful: old shoes. They are exactly
what you need for jobs that involve
getting dirty. Such jobs include painting,
raking or cleaning. Old shoes are just
right for situations where you are bound
to get wet, such as washing the car or
watering the lawn. When you don’t
want cleanliness to interfere with
having fun, old shoes are the answer.
Considering their usefulness, old shoes
should be cherished, not tossed into
the trash can.
