Read the passage carefully, then choose the correct answer – A, B, C, or D.
Most people are afraid of sharks, but they usually do not know much about them. For example, there are about 350 species of sharks that live in oceans over the world. All of the sharks are carnivores, but most of them don't attack people. Some sharks are very small - the smallest shark is about 6 inches long - about as long as your hand. But some sharks are very large. The largest species of sharks may be 60 feet long and weigh 15 tons. Unlike many other kinds of fish, sharks do not have bone. Their bodies are made up of a kind of tough white flexible material (called cartilage). Sharks do not have ears. However, they 'hear’ sounds and movements in the water. Any sound or movement makes the water vibrates. Sharks can feel these vibrations, and theyhelp the sharks find food. Sharks use their large eyes to find food, too. Most sharks see best in low light. They often hunt for food at dawn, in the evening, or in the middle of the night.
Nowadays scientists want to learn more about sharks for several reasons. For example, cancer is common in many animals, including, people. However, it is rare in sharks. Scientists want to find out why sharks almost never get cancer. Maybe this information can help people prevent cancer, too.

Man is a land animal, but he closely tied to the sea. Throughout history the sea has served the needs of man. The sea provided man with food and convenient way to travel to many parts of the world. Today, nearly two thirds of the world's population live 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 of man's needs.
The list of riches of the sea yet to be developed by man's technology is impressive. Oil and gas exploration has been carried out for nearly 30 years. Valuable amounts of mineral 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 of fish and shellfish is an ancient skill practiced in the past mainly by the Oriental people.
Besides oil and gas, the sea may offer new source 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 sources of the sea will be largely solved.
