The summer beach season is prime time for shark attacks. It seems like sharks are attacking all the time. But that is something of an illusion. The number of attacks is very small.
How does a shark hunt? Muscles and fins give the shark its speed and maneuverability in the water. A shark’s front fins act like the wings of a plane and let it “fly” through the water. The tail acts like a high-power propeller
But the big thing that gives the shark its edge in the ocean is its sensory package. The package includes the shark’s eyes, ears, skin, nose and mouth, as weir as electric sensing.
A shark’s nose is probably its most important sense. If you were to put a single drop of blood in a swimming pool, a great white shark could smell that. And they can tell the direction that the smell is coming from.
Sharks handle their electric sensing using cell located in the head. Whenever something moves using its muscles, a shark can detect the electrical impulses flowing to those muscles. A shark can electrically “see” anything that has muscles even if it is hiding or the water is not clear.
Sharks even have vibration sensors in their skin. Even something moves near the shark, tubes pick up the pressure changes and hairs inside the tubes send signals to the brain. This extra sense allows a shark to turn quickly and attack again.
When you put all these different senses together , it makes the shark a nearly ideal hunter. A shark can detect prey from miles away and then use eyes, electrosensing and movement sensing to home in.
Strangely, sharks do not seem to use these senses to home in on people. The very low number of sharks tells us that sharks do not hunt people in a regular basis. On the other hand, people love to hunt sharks, Millions of sharks die every year. Without protection, extinction is a definite possibility.

Professional adventurer Mike Horn never met a challenge he didn’t welcome. In fact according to Horn, “The impossible exists only until we find a way to make it possible.”
As a child in Johannesburg, South Africa, Horn excelled at sports and loved adventure. But it wasn’t until he moved to Switzerland in 1990 that his life of adventure really began.
Horn had always loved sports and taking risks, and he was known for his crazy feats. He traveled in the South American Andes Mountains in the early 90s and then in 1997 crossed the entire continent on foot. He finished by floating 7,000 km down the Amazon River!
In 1999, H orn began a solo trip around the world following the equator,without the use of any motor-powered transportation. When he finished successfully 17 months later, he became the first person to accomplish the feat.
Horn’biggest challenge to date came in 2006. He and a fellow adventurer walked from Russia to the North Pole in the sunless winter. Traveling through the winter darkness, he encountered polar bears and many other dangers.
In 2008, Horn began another unique adventure –one that will take four years to complete. Instead of trying to achieve more personal goals, Horn is now dedicated to sharing his knowledge and experience with others.
He calls his latest expedition the “Pangaea Expedition.”with “Pangaea” standing for “a Pan Global Adventure for Environmental Action.”By the end of this expedition, Horn will have traveled 100,000 km and crossed all of the continents and oceans. But this time he won’t be going alone: He’s choosing young people from around the world, aged 13 to 20, to accompany him. Twelve young men at a time will participate in one of 12 different projects, ranging from studying glaciers to treating water sources.
The journey will take place onboard Horn’s 35-meter saiboat , the Pangaea which will become a floating science class . Along with a team of scientists, Horn plans to teach the young explorers about protecting and preserving the earth.
In perhaps his most important expedition, Horn will pass down his passion for Earth’s wonders to the next generation.
64.Which of the following is NOT ture?

One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. “I knew it wasn’t the moon”, he said. “I drive this road all the time and I notice little things out of place.”
Duffy stopped his car and got out to examine. Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail. His car fell and rolled end over end, landing on its top more than two hundred feet below.
Duffy rushed to call for help, then returned and got down to reach the injured driver. Snow covered the valley and the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the injured man in time, along with the blankets from his car.
Life-saving deeds are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning.

This is a true story from Guyana. One day, a boy took a piece of paper from a box. He made a paper ball and pushed it into his nose. He couldn’t get it out. He ran crying to his mother. His mother couldn’t get the paper out, either. A week later, the paper was still in the boy’s nose. His nose began to have a bad smell.
So his mother took the boy to a hospital. The doctor looked up at the child’s nose, but she couldn’t get the paper out. She said she had to cut the boy’s nose to get the paper out.
The boy’s mother came home looking sad. She didn’t want her child to have his nose cut. The next day she took the boy to her friend Sidney who lived in a house with an old lady called May. May wanted to see the child, so the child let her look up his nose.
“Yes, I can see it,” May said. “It will be out soon.”
As she spoke, she shook some black pepper on the child’s nose. The child gave a mighty sneeze and the paper flew out. His mother was surprised. May told his mother to take the boy to the seaside for a swim, for the salt water would go up his nose and stop the bad smell.

Dear Sir/Madam,
I read Alison Burnham’s review of When We were 12, and I do not agree with her. I thought the programme was wonderful — I found the old news pictures really interesting — they helped to bring to life the stories the people were telling.
The programme reminds me of many things from my own childhood. For example, one day when I was about five, I was going to school on the bus by myself (this was the late 1960s). My mother had given me exactly the right money for a return ticket. I held out my hand with the money in it — one big coin on top of one little coin. The bus conductor took the big top coin only and she gave me a ticket, but it was a pink one for a single journey. I needed a white one for a return journey, but I was too frightened to say anything. When school finished for the day, I couldn’t catch the bus home — I had to walk. As a grown-up, whenever I’ve been in a situation where I need to say something or take some action, this early memory of my bus ride comes back to me, and I’m able to take control of the situation.
I would like to say to the director, Bret Chrysler, carry on making this kind of programme. Too much TV these days is quiz shows and so-called “reality programmes”. I appreciate the human story that can make me laugh and cry.
Chris Daniels
72. What is Chris Daniels’ purpose of writing this letter?
A. To persuade Bret Chrysler to turn away from quiz shows.
B. To entertain other readers with old news pictures.
C. To express his appreciation of the programme.
D. To have his story told on the programme.
73. Chris Daniels tells the story about the bus ticket to_____.
A. describe how painful his early experience was
B. draw a direct response from Alison Burnham
C. show how the programme made him think
D. teach the readers of TV Weekly a lesson
74. According to the passage, Chris Daniels had to walk home because_____.
A. he hadn’t got a return ticketB. he had lost his bus ticket
C. he didn’t like big crowds D. he missed the bus home
75. What does Chris Daniels now think about his experience on the bus?
A. He should have told the conductor then. B. He should have been well treated.
C. He regrets going to school alone. D. He wishes it hadn’t happened.
