The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two thirds of the world's population live within 80 kilometres 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 of 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 exist on the ocean floor ready to be mined. Fish farming promises to be a good way to produce large quantities of food. The culture offish and shellfish is an ancient skill practised 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 2000 the problems that prevent us from exploiting fully the food, minerals, and energy sources of the sea will be largely solved. 46.

Carbon dioxide in the atmosphere, which is primarily a result of mankind's burning fuels, is thought to act like the glass of a greenhouse. It absorbs heat radiation from the earth and its atmosphere, the heat that otherwise would dissipate into space. The possibility that the greenhouse effect could alter the earth's temperature has been debated for many years. Scientists have agreed that carbon dioxide is increasing but there has been uncertainty about whether temperatures are also increasing. The major difficulty in accepting the greenhouse effect has been the absence of observed warming coincident with the historic carbon dioxide increase. 46. The principal consequence of the greenhouse effect is assumed to be an increase in A. global temperatures B. the building of greenhouses C. the burning of fossil fuels D. the sun's radiation reaching the earth 47. The word " dissipate " in the first paragraph means A. evaporate B. disappear C. thaw D. discolour 48. The carbon dioxide in the atmosphere is believed to produce the greenhouse effect by A. being burned on the ground B. dissipation into outer space C. being widely used for agricultural purposes in greenhouses D. preventing heat radiation from escaping the earth's atmosphere 49.

Read the text and questions below. For each question, circle the letter you choose A, B, C or D. A recent investigation by scientists at the U.S Geological Survey shows that strange animal behaviour might help predict future earthquakes. Investigators found such occurrences about ten kilometres from where a fairly recent earthquake took place. Some birds made strange sounds and flew about wildly, dogs barked and ran around uncontrollably. Scientists believe that animals can sense these environmental changes as early as several days before the disaster. In 1976 after observing animal behaviour, the Chinese scientists were able to predict a terrifying earthquake. Although hundreds of thousands of people were killed, the government was able to evacuate millions of other people and thus keep the death toll at a lower level. 46. What prediction may be made by observing animal behaviour? A. A likely earthquake. B. The number of people who will be killed. C. The number of people who will be evacuated. D. Environmental changes. 47. Why are animals aware of these changes when humans are not? A. Animals are cleverer than humans. B. Animals have certain instincts that humans do not. C. Animals can feel the shaking of the earth by running around the house. D. Humans don't know where to look. 48. Which of the following is NOT TRUE according to the passage? A. Some animals may be able to sense a coming earthquake. B. By observing animal behaviour, scientists can predict earthquakes. C. The Chinese scientists have successfully predicted an earthquake and saved many lives. D. All birds and dogs in surrounding areas went wild before the earthquake. 49. In this passage, the word evacuate (in the last paragraph) most nearly means A. remove B. replace C. exile D. drive 50. If scientists can accurately predict earthquakes, there will be A. fewer animals going wild. B. a greater number of survivors. C. fewer people evacuated. D. fewer environmental changes.
