Read the following passage carefully.
Dr. Charles Turner was a respected scientist who was always interested in nature. As a boy, he showed this keen
interest in nature by investigating the behaviour of animals. After he completed college, he devoted his time to scientific research as well as educating young, black people. He was a biology teacher who did his research at home. It was a common sight to see his children surrounded by snakes, bees, ants and other animals in their father’s laboratories. Perhaps the most important aspect of his research was on the behaviour of insects. He discovered that ants are guided

to their homes by light rays. He also discovered that bees memorize the area in which they live so that they don’t get lost. He realized that bees recognize the differences in colour and pattern.

He earned just a small salary but had a brilliant mind which was the reason for his great success. The following questions are about the passage which you have just read.

My mother called to me to ensure the windows were closed. I think it was really to reassure herself that I was inside
doors. A bolt of lightning flashed menacingly in the sky, followed by the low rumbling roar that reverberated throughout the house. I was elated at the magnificent downpour. Through the louvered windows I watched gleefully as the waters cascaded over the drain pipes and collected in the canals below. The canals swelled and overflowed and my heart raced. I could hear my mother busying herself in the kitchen. Eagerly, I rushed to get my discarded exercise books and put my expert boat-
making talents to work. I was skilful and nimble at my task. In no time I had completed a perfect paper boat. Then I waited patiently. Soon the rain had slowed to a drizzle. Then it ceased altogether. I quietly opened the front door, looked back
furtively and then darted outside. My friends had already gathered around the canal, filled with rushing, rain water. We set our boats and raced along beside them as they swirled and dipped in the unsteady waters. My boat was in the lead and I shouted joyfully. Suddenly, the boat became entangled with a broken twig. It circled the twig desperately and then was engulfed in the rapidly flowing waters. I stopped abruptly in dismay. I turned and retraced my steps slowly home.

CONJUNCTIONS (cont’d)
Remember that a conjunction is a word used to join words, phrases or sentences. Types Of Conjunctions There are three types of conjunctions. 1. Co-Ordinating Conjunctions : These join words or groups of words of the same part of speech and of equal value. For example:

The conjunction and joins the two nouns book and pen. Kasean arrived home tired but very happy. 2. Correlative Conjunctions : They are used in pairs to join words or groups of words. Examples:

3. Subordinating Coniunctions:
A subordinating conjunction joins a clause that cannot act as a
sentence on its own with a clause that can act as a sentence on its own. For example: When we arrived at school, nobody was there. If you tease that dog it will become angry. Underline the conjunctions in the following sentences. 1. The priest stood at the door and greeted the worshippers. 2. She wanted rice but there were none. 3. Neither Kevin nor Kim wants to study. 4. He acted as though he was royalty 5. Since we are of African descent we must be aware of our African Heritage. 6. Either the monkeys or the wandering chickens have destroyed the lettuce. Join these pairs of sentences using suitable conjunctions. 1. Pansy swept the floor. Annalee put out the washing. ___________________________________________________________________________ 2. Kito arrived late for school. His father’s car broke down. ___________________________________________________________________________ 3. Unplug the iron. Press this shirt for your sister. ___________________________________________________________________________ 4. I did my chores quickly.

Comparing Adverbs Adverbs, like adjectives, can also be used to show comparison. The adverb can be used to compare the actions of two or more persons or things. Adverbs also use the comparative and superlative forms or degrees in comparing. The comparative form of the adverb compares two actions and the superlative form compares more than two actions. 1. If an adverb has only one syllable, -er or -est is usually added.
2. For adverbs which end with -ly and those which have three or more syllables a. add more or less for the comparative
b. add most or least for the superlative For example: Trisha sings sweetly. (positive) She sings more sweetly than her sister (comparative) However, Tia sings most sweetly than all the girls.
(superlative) 3. Some adverbs do not follow the general rules of comparison. We call these irregular adverbs. They do not use NATION WORKBOOK

DECIMALS (cont’d) Rounding decimals
For numbers written in decimal notation, decimal place is the position of a digit to the right of the decimal point. For example, in 2.079, there are three decimal places. 0 is in the first decimal place, 7 is in the second decimal place, and 9 is in the third decimal place.
We can write decimal place as dp.
Numbers written in decimal notation may be rounded to a certain number of decimal places. The same rules for rounding numbers apply:

FINDING PERCENTAGES OF QUANTITIES In the box to the right there are 100 masks. If you have 100 percent of the masks, how many would you have? Yes, you would have all the masks, that is, 100 masks.
When you have 100 % of something, you have all of that something. There are times when quantities are not exactly 100 percent. If I gave you 25 % of the 100 masks, how many would you have? Discuss your answer with your teacher/ parent telling how you arrived at your answer.

STATISTICS Sometimes diagrams are used to represent information or data that is collected. There are several ways of representing this information or data.
A) THE BAR GRAPH
One such way is by a graph. There are different types of graphs. Today we look at one type:
The bar graph is so called because it is made up columns which look like bars. Each column has the same width but the height can be different. The spaces between the columns are also the same. The bars may be drawn either in a vertical or horizontal position.
