On a cool November afternoon in Fleming Island, Florida, Melissa Hawkinson, 41, was driving her five-year-old twins home from school when she saw a sudden splash in Doctors Lake just ahead. What was that? She thought. As she drove up to the scene, she saw a half-submerged car sinking about 30 yards offshore. “It was going down pretty quickly,” Hawkinson recalls. She stopped the car near the boat ramp and ran toward the water. Water is going to be cold, she thought.

She took off her vest and leather boots, got into the icy water, and swam to the car, where she found Cameron Dorsey, five, trapped into his car as the swirling water rose around him.

Hawkinson tried to open the door, but it was locked. So she pushed and pulled hard on the partially open window until she could reach through and unlock the door. She pulled the boy free, swam to shore, and handed him off to onlookers who were only watching them on a dock. The driver, the boy’s suicidal father, swam back to land on his own. Afterward, Hawkinson sat on the shore wrapped in a blanket. “For ten or 15 minutes, I couldn’t stop shaking,” she said.

There’s nothing visibly extraordinary about Melissa Hawkinson, an energetic stay-at-home mom with brown hair and a sweet smile. Yet something made her different from the dockside onlookers that day. Why do some people act quickly, willing to take a risk for a stranger? What makes them run toward danger rather than away from it? Hawkinson, the Granite Mountain Hotshots (能手，高手)---19 of whom lost their life this past summer in Arizona--- every hero who puts his or her life on the line to save another: what makes them brave?

Moreover, can bravery be learned, or is it a quality with which you are born? The answer is complex. Bravery taps the mind, brain and heart. It comes from instinct, training and sympathy. Today, neurologists, psychologists and other researchers are studying bravery, trying to uncover the mystery.

1.It can be learned from the passage that _______.

A. Melissa Hawkinson was a 41-year-old nurse

B. it was spring when the accident happened

C. Melissa Hawkinson was picking up her five-year-old son

D. Melissa Hawkinson was kind and courageous.

2.What conclusion can we draw from the third paragraph?

A. Not everyone was ready to risk saving the five-year-old boy..

B. The father committed suicide because of the divorce.

C. The father was saved in the end by Melissa Hawkinson.

D. No one else was available except Melissa Hawkinson.

3.How does the writer find other people on the dockside?

A. Warm and ready to help B. Thoughtful

C. Kind of cold-blooded D. Not skillful at swimming

4.What is the writer’s purpose of writing this passage?

A. To set us thinking what makes people brave.

B. To call on us to learn from such people as Hawkinson.

C. To remind people of risk while saving others.

D. To show people bravery can be learned.

The predictability of our death rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot themselves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota (定額) for each type of death. It just happens that they follow a consistent pattern year after year.

A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained strangely static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an interesting theory called “risk homeostasis”. According to this theory, people naturally live with a certain level of risk. When something is made safer, people will get around the measure in some way to get back to the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt offers. Other studies have shown that where a crossing is made safer, the accident rate invariably falls there but rises elsewhere along the same stretch of road as if making up for the drop. It appears, then, that we have an inborn need for danger. In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn’t simply a matter of paying attention to certain precautions such as eating the right foods, not smoking, and driving with care. You must also have the right attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.
