IX. Read the following passage and mark the letter A, B, c, or D on your answer sheet to indicate the correct answer to each of the questions.
It is a common saying that we do not fully value a thing until we lose it. We often value the love and worth of a friend when he has been taken from US by death more than when he was with US in the flesh; it is only when we have left school or college that we understand the greatness of our opportunity of education, which has gone forever; and it is the sick and the ailing who realize the value of good health, when we are young and strong, we cannot imagine what it is to be weak and ailing. We are so used to vigorous health that we take it for granted. The organs of our body work so smoothly that we scarcely know we have lungs and liver, heart and stomach. But when any of these gets upset and gives US pain and sickness, we learn by bitter experience what an unspeakable blessing it is to be well.
Loss of health makes US miserable, and a burden to ourselves and our friends. It cripples our efforts so that we cannot accomplish many of the good and great things we might have done. It spoils our life. What must we do to keep our health?
We must be moderate in eating and drinking and wise in the choice of plain, wholesome simple food. Gluttony has killed thousands, and strong drink tens of thousands. We must, when young, get plenty of sleep, which is "nature's sweet restorer", and not try to burn the candle at both ends. We must live as much as possible in the open air and keep our rooms well ventilated. We must get sufficient and regular physical exercise, and keep our bodies clean. And we must avoid bad habits and secret sins as we avoid the devil, and keep our thoughts clean and our bodies pure. Our ideal must be the sound mind in the sound body.

IX. Read the following passage and mark the letter A, B, c, or D on your answer sheet to indicate the correct answer to each of the questions.
Man is a land animal, but he also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and convenient way to travel to many parts of the world. Today, nearly two thirds of the world's population lives within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many man's needs. The list of riches of the sea yet to be developed by man's technology is impressive. Oil and gas explorations have been carried out for nearly 30 years. Valuable amounts of minerals existing on the ocean floor are ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental people.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong, new materials has made this possible. The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent US from exploiting fully the food, minerals, and energy source of the sea will be largely solved.

For many years, people believed that the cleverest animals after man were chimpanzees. Now, however, there is proof that dolphins may be even cleverer than these big apes.
Although dolphins live in the sea, they are not fish. They are mammals. They are in many ways, therefore, like human beings.
Dolphins have a simple language. They are able to talk to one another. It may be possible for man to learn how to talk to dolphins, but this will not be easy because dolphins cannot hear the kind of sounds man can make. If man wants to talk to dolphins, therefore, he will have to make a third language which both he and the dolphins can understand.
Dolphins are also friendly towards man. They often follow ships. There are many stories of dolphins guiding ships through difficult and dangerous waters.
