Have you ever played with words? We can play a
guessing game out of words. We can combine letters to form
new words. A new word learned everyday will increase your
speaking and writing vocabulary.
In this module you will learn to make a new word using
prefixes and suffixes. Do you know what prefixes and suffixes
are? If you don’t, this module will teach you what suffixes and
prefixes are.
This module will teach you the following:
-making new words with the use of prefixes and suffixes
-identify meaning of unfamiliar words through the use of
prefixes and suffixes
Read and study all the exercises in this module.
Good luck!

Once upon a time, the birds in the air had a misunderstanding with the beast of the earth. Each camp fought butterfly against the other, and the outcome of the fight was uncertain for some time. The bat, knowing he had the looks of both bird and beast, did not want to take sides in the foolish conflict.
The birds begged him to join them, but the bat woefully shook his head and said, “I am a beast! When the beast invited him to their camp, the bat sadly said, “I can’t.”
After a long time, the birds and the beast got tired of continuous fighting. Finally they agreed to end their destructive war, and peace at once settled among them. There was much rejoicing in both camps.
When the bat learned that the fight was over, he went to the bird’s camp to join the celebration. But the birds quickly flew away as soon as they saw the bat. Then the bat went to the beasts, but he was told that he was not welcome to their feasting.

Here i s another story. Thi s i s real i stic story. It i s true to li fe. Read i t wel l and thi nk of the harmful effects of usi ng drugs.
Drugs Are Dangerous
One of the big problems of teenagers today is drug addiction. Some take drugs because they are curious. They want to find out how drugs will affect them. Others use to forget or escape from their problems.
Doctors say that drugs are highly dangerous, especially when they are used without medical prescription. Although drugs are of different kinds, their effects are generally the same. A large dose of drugs can cause jitters, irritation, slurred speech, and tension. Drugs increase the heart beat, raise the blood pressure, dilate the pupils, and decrease the appetite.
People who take drugs have difficulty in thinking. They often see and hear imaginary things so that they appear to be abnormal. They become talkative,
unsteady or drowsy, and find it hard to coordinate their movements. Drugs users find it hard to make god decisions.
Medical authorities say that drugs can cause dry mouth, sweating, headache, diarrhea, and paleness. An overage of drugs can cause death.
It is a serious crime to keep dangerous drugs or to give or sell them. If you are found guilty of violating the low on drugs, you may not be allowed to enter a
profession such as medicine, law or teaching. It may also be very difficult for you to get a job in the government, business or industry.
GRADE IV
Answer the questions orally.
