First, the sun makes
water warm.
Next, the water goes up in
the air and becomes clouds.
Then, the clouds meet cool air
and turn into water drops.
And then, the water drops fall
down to the earth. That is rain .
Oh, it's a long journey !
That is the water journey.
Finally, water goes back to
the rivers, lakes and seas.
First, cut the boiled
egg into pieces.
Next, add a little salt, pepper
and some mayonnaise. Mix
them well.
Then, cut the
cucumber and
sausage into pieces.
Put all of these on a piece of
bread, and then top them
with a second piece.
Put the mixture on the
bread and top it with a
third piece, and then
the sausage pieces.
Finally, top the sandwich with
a fourth piece. Cut the
sandwich in half.
Save water, save ourselves !
Water is important to our life. If there is no water, there is
no life on the earth. People, animals, and plants all need water.
We use water to grow food and cook meals. We use water to
keep the grass green and the clothes clean. And we use water
to clean our cars, houses and ourselves ! Besides, we use
water to get fun !
See you !
