Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.
Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants. Other sharks are killed for sport and out of fear. Sharks are vulnerable(易受伤的) to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring（后代）.
Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine（海洋的） mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.
If you are a typical ocean-goer, your chances of being killed by an unprovoked（非受挑衅而发生的）attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car.
Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.
Sharks are among the few animals in the world that almost never get cancer and eye cataracts（白内障）. Understanding why can help us improve human health. Chemicals taken from shark cartilage（软骨）have killed cancerous tumors in laboratory animals, research that someday could help prolong your life.
Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.

D
Are you afraid of sharks? You shouldn’t be! Below we cleared up the main myths about one of the world’s most perfectly formed creatures …
All sharks are the same.
This is absolutely not true. There are nearly four hundred species of sharks and they vary widely in habitat, size, features, diet and lifestyle. They range from the cigar shark, which is about 15 centimetres long, to the whale shark, which can be up to about nine meters long. More than 50 percent of sharks are less than a metre long and more than 90 percent are less than two metres long. And their habitat ranges from shallow to deep water and from the Arctic to the Tropic.
___________________
This is not true, either. In fact, many shark populations are decreasing. The chief reason for this is that hundreds of thousands of them are caught in fishing nets. Depending on where they are caught. They are either killed for their fins(鳍), which are used in shark’s fin soup, or they are tossed back into the sea because they are unwanted. Almost all sharks which are discarded in this way die. Also, sharks mature late in life and produce very few young. If the current reduction in numbers continues, the ecological balance of the oceans will be severely threatened.
Sharks will always attack you
This is nonsense. The chances of being attacked by a shark are minimal. You are 250 times more likely to be killed by lightning than by a shark, and your chances of being killed by lightning are practically zero.
However, if you are planning to take a swim in shark territory, then follow these simple rules:
Avoid swimming at dawn or duck when visibility decreases.
Avoid areas where there are breaking waves. Turbulent(汹涌的) water makes it difficult for sharks to see and determine whether you are prey(猎物).
Do not wear jewellery in the water. Sharks are attracted to shiny fishes, and jewellery may resemble their scales(鳞片).
Do not swim near schools of small fish, which are the favorite food of some sharks.
68. The underlined word “myths” in the first paragraph means ____.
A. an idea or story that many people believe but which is not true
B. something that is impossible to understand or explain or about which little is known
C. a feeling of surprise
D. something that you are curious to know
69. From the passage we can learn sharks ____.
A. look alike B. are dangerous
C. usually live in deep sea D. hardly attack people
70. Which of the following is proper for the blank in the third paragraph?
A. Sharks’ fin soup is nutritious
B. There are too many sharks in the sea
C. Many shark populations are decreasing
D. Sharks produce many young
71. Which of the following rules should you follow when you’re going to swim in shark areas?
A. Don’t swim before day breaks.
B. Choose areas where there are big waves.
C. Wear something shiny when swimming.
D. Choose areas where there are many small fish.
