Read the passage below and answer the questions that follow

Developers’ bulldozers have been leveling thousands of acres of rain forest every day in recent years to make way for human habitation. As a result, one plant or animal species a day is added to the list of those that have become extinct on this planet. This destruction must stop. Rain forests must be protected because they offer the human race many irreplaceable resources.

Rain forests are a special category of forests found only in the tropical regions of the world, usually close to the equator. True to their name, rain averages 80 inches a year in these forests. This rain, coupled with the warm tropical temperatures, crates dense lush vegetation. Little light gets through to the ground, but on the canopy and immediately below on the trees, plant and insect life abounds and is rich with benefits for humanity.

4

One major use of rain forests is biomedical. The plants and animals found there are a source of many rare compounds used by pharmaceutical companies. It is the products of such companies that suffers of Parkinson’s disease and certain mental conditions have to thank. And the discoveries have just begun. Scientists say that rain forests contain over a thousand plants that have great anticancer potential. To destroy life forms in these forests is to deprive the human race of further medical advance.

Another reason for saving rain forests is the crucial role they play in maintaining the global natural balance. Living organisms exist with each other, meaning that when one is eliminated, another can over-multiply to the detriment of the environment for example, when developers clear forested areas to make way for “civilization”, birds lose their nesting sites and no longer eat the insects there. These insects flourish and attack farm crops. The subsequent destruction of agriculture causes a serious food shortage and as we know, a hungry nation cannot develop.

Most important, rain forests must be protected because their trees regulate the planet oxygen supply. They help to balance atmospheric conditions by manufacturing oxygen and absorbing carbon dioxide. Carbon dioxide creates what is called the “greenhouse” effect, process that is responsible for global warming which in turn could lead to the sub-merging …………….. coastal regions and islands. Can you imagine waking up one morning to the announcement that Mombasa, Lamu and Rusinga Islands are no more?

Also, rain forests regulate the climate. If they are destroyed, the greenhouse effect could change rainfall patterns so that areas formally used for agriculture become deserts. We may not be there yet, but are not really already contending with uncharacteristic long dry spells that bring about future.

In future, the pressure on rain forests will become worse, not better, given that the human population keeps growing. The pessimist believes nothing can be done. The optimist, on the other hand, strongly believes that people can work together to slow even reverse, the pace on destruction. Stand up to be counted.

SECTION B

Read the oral narrative below and then answer the questions that follow

The fox and the Crow

A fox once saw a crow fly off with a piece of cheese in its beak and settle on a branch of a tree.

“That’s for me, as I am a fox,” said Mr. Fox, and he walked up to the foot of the tree.

“Good day, Ms. Crow,” he cried. “How well you are looking today: how glossy your feathers

how bright your eye. I feel sure your voice must surpass that of other birds, just as our figure

does. Let me hear but one song from you that I may greet you as the Queen of Birds.”

The crow lifted up her head and began to caw her best, but the moment she opened her mouth the

piece of cheese fell on the ground, only to be snapped up by Mr. Fox. “That will,” said he.

“That was all I wanted. In exchange for your cheese I will give you a piece of advice for the

future-“Do not trust flatterers!”

(Adapted from Prentice Hall Literature,Ed. Roger Babusci et al. Englewood Cliffs,

SECTION C

Read the following poem then answer the questions that follow

I speak for the Bush

When my friend sees me

9

He swells and pants like a frog

Because I talk the wisdom of the bush!

Do not understand civilized ways

For we tell our women

To keep the them of their dresses

Below the knee

We from the bush, my friend insists,

Do not know how to ‘enjoy’

When we come to the civilized city

Like nuns, we stay away from nightclubs

Where women belong to no men

And men belong to no women

And these civilized people

Quarrel and fight like hungry lions!

But, my friend, why do men

With crippled legs, lifeless eyes,

Wooden legs, empty stomachs

Wander about the streets

Of this civilized world?

Teach me, my friend, the trick

So that my eyes may not

See those whose houses have no walls

But emptiness all around

Show me the wax you use

To seal your ears

To stop hearing the cry of the hungry;

Teach me the new wisdom

10

Which tells men

To talk about money and not love

When they meet women.

Tell your God to convert

Me to the faith of the indifferent

The faith of those

Who will never listen until

They are shaken with blows

I speak for the bush!

You speak for the civilized-

Will you hear me?

Everett Standa
