day Kashif went shopping with his mother. As he was very fond
off sweets, he asked his mother if he might buy some.
Mother: No, no, Kashif. You shouldn't buy
any sweets from this shop. See, flies ale sitting on them.
If you eat those sweets you will fall ill.
Kashif: All right, Mother, let's walk across the
road. Look, here is another shop. Shall we buy some from here
Mother: Yes, it's a clean one. There are
no flies. Oh, no. I have just seen a man sweeping the road
by the shop.There is a lot of dust. You oughtn't eat anything
if there is dust on it. Flies and dust carry hundreds of germs
and they are enemies of our health.
Kashif: Please Mother, tell me more about
Mother: Listen very carefully. These germs
are the smallest living things. They cannot be seen with the
naked eye. You only see them through a microscope.
Kashif: How do the flies carry them?
Mother: You have seen flies sitting on dirty
things. There are germs on these things and they stick to
the flies' legs. When the flies sit and walk on our food the
germs stick into it. And when we eat that food the germs get
into our bodies and make us ill.
Kashif. Oh, I see! So, we should never eat
such sweets and food that are not properly covered.
Mother: Dust also carries germs. We can't
see them, but the air is full of them. So,you must remember
not to eat food if flies have been sitting on it or if there
is dust on it.
Kashif: Right I won't buy anything from these
shops where things are not properly covered.
Mother: A great many diseases are caused
by these germs. For instance, the germs of typhoid and several
other diseases are carried by flies.
Kashif : But, Mother; I have read in my book that malaria
is caused by a kind of mosquito and not by
Mother: True. You are right. One can get
malaria from a mosquito bite.
Kashif: Where do the mosquitoes live?
Mother: They live in stagnant water. Some people use kerosene
oil and D.D.T. to kill the mosquitoes before they are big
enough to fly away and bite healthy people.
Kashif: If everybody in Pakistan takes part
in the fight against mosquitoes, we will soon get rid of malaria.
Mother: Yes, my son, I think so too. We should
try to keep ourselves healthy as "Health is Wealth".
If we are not healthy, we won't be able to work hard, study
