"Shark on the bait （诱饵） !" shouted Andre Harman, pointing to a spot a few yards behind the outboard motors． His voice gave no indication of panic, but the crew suddenly became tense and fixed their eyes on the water． Slowly, smoothly, Andre drew in the bait．The shark followed． No one asked what kind of shark it was． Everything about it, from its color to its shape, tells that it was a great white shark．

Andre lifted the bait aboard． Placing himself between the two motors, he dropped his right hand into the water just as the great head reached the first motor．“My goodness Andre!” I said． His hand seized the big nose, moving it away from the tube of the motor, guiding the shark's head up as it rose out of the water． Andre's hand held the nose, touching it gently． No one spoke． No one breathed． The moment seemed endless． In fact, it lasted less than five seconds before Andre pulled his hand back．

Still nobody spoke． Then Andre smiled and said: "The first time was an accident． I was just trying to move the shark away from the motor． Sharks are attracted to motors by r．heir electrical signals and have a habit of biting them to see if they are eatable． " Andre has worked with great white sharks for years． "My hand landed on its nose, and it sort of paused, so I kept it there, and when I did let go, the shark bit and bit as if it was searching for whatever it was that had attracted it．"

Nearly every encounter （遭遇） we had had with the great whites had been totally illogical． The more we learned, the more we realized how little was really known about them in the past years． Back then, it was generally accepted that great whites ate people by choice． Now we know that almost every attack on a human is an accident in which the shark mistakes a human for its normal food． Back then, we thought that once a great white smelt blood, it would lead to death． Now we know that nearly three-quarters of bite victims survive, perhaps because the shark recognizes that is has made a mistake and doesn't return for a second bite．

1.The author said, "My goodness! Andre ! " when ________．

A．Andre was about to fall into the water

B．Andre was about to touch the shark

C．Andre was followed by the shark

D．Andre was bitten by the shark

2.What does the author think of the encounters with great whites________.

A． Exciting． B．Educational．

C． Frightening D． Reasonable

3. Most bite victims survive in shark attacks because________.

A．they are taught how to fight off sharks

B．sharks discover they are no threats

C．they manage to swim to safety

D．sharks stop attacking them

Cleverness is a gift while kindness is a choice．Gifts are easy—they’re given after all．Choice can be hard．

I got the idea to start Amazon 16 years ago．I came across the fact that the Internet usage was growing at 2300 percent per year．I’d never seen or heard of anything that grew that fast，and the idea of building all online bookstore with millions of titles was very exciting to me. I had just turned 30 years old，and I’d been married for a year．I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t and I wasn’t sure what to expect．MacKenzie told me I should go for it．As a young boy，I’d been a garage inventor．I’d always wanted to be all inventor，and she wanted me to follow my passion．

I was working at a financial firm in New York City with a bunch of very smart people and I had a brilliant boss that I much admired．I went to my boss and told him I wanted to start a company selling books on the Internet．He took me on a long walk in Central Park，listened carefully to me，and finally said，“That sounds like a really good idea，but it would be an even better idea for someone who didn’t already have a good job．”That 1ogic made some sense to me，and he convinced me to think about it for 48 hours before making a final decision．Seen in that light,it really was a difficult choice，but finally，I decided I had to give it a shot．I didn’t think I’d regret trying and failing．And I suspected I would always be haunted by a decision to not try at all.

After much consideration ，I took the less safe path to follow my passion ，and I’m proud of that choice．For all of us，in the end，we are our choice．

“Keep your eyes on the ball.” That is good advice when you are on the playing field, and good advice for everyday life. “Keep your mind on what’s important,” is the way I’d put it. But people are funny. They think too much about the details.

I had a secretary once. She was very hardworking. I ran a school and people used to call up to enroll(登记) for courses. Berry used to get angry at the phone. “If they keep on ringing, I’ll never get my typing done!” she’d shout.

People just don’t see the big picture. One evening, after leaving work, I was sitting next to a man on the train. I was feeling tired. My eyes fell on the paper he had spread out in front of him. You know how you feel to read over someone’s shoulder?

I read the page and leaned back. I guessed I was waiting for him to turn it. After a while, I realized—he wasn’t turning the page. He just kept on reading.

Now if you knew the page he was reading, you’d know that there weren’t many words on the page to read anyway. The layout（版面） was mostly pictures. So I turned to the man and said,” You know, you really read very slowly.”

“What do you mean?” he asked. “Well,” I told him, “I read the page in about a minute, and you have taken about ten. And you are still reading. You know,” I went on “If you learned to read faster, you could get more reading done.” He remained silent for a minute or two. “If I read too fast, my paper wouldn’t last me to my station.”

1.The writer wasn’t satisfied with his secretary because ___.

A. she didn’t put first thing first

B. she was too busy

C. she was easy to get angry

D. she couldn’t finish her work on time

2.The man read newspaper in order to___.

A. take in information B. enjoy pictures

C. save time D. kill time

3.The writer thinks that people seem to need a sense of ___.

A. what to read first B. how to read fast

C. what is important D. what is funny
