Ben Underwood is blind. Both eyes were removed when he was just three years old, leaving him with no vision at all. So how on earth does he ride his bicycle, play football and basketball?

Ben uses many common aids for the blind, like speaking software. He's also written a book and does his schoolwork on a hi-tech Braille writer. But what’s unusual is what he doesn’t use. Ben has no guide dog and never uses a white cane. He doesn’t even use his hands. Instead, he sees with sound. Amazingly, Ben’s ears pick up the echoes(回聲）and he can precisely locate where things are. Ben is the only person in the world who sees using nothing but echolocation.

Ben was born perfectly healthy, with dark eyes like his mum. But, when he was two she looked into his eyes and saw something was terribly wrong. This is a rare infant eye cancer that affects only one in every six million. In an attempt to save his sight, doctors immediately began intense chemo and radio therapy, but like a lead balloon. His eyes had been removed.

Just one year after the operation to remove his eyes, in the car he asked his mum what the big building was that they were passing. Ben’s ears were picking up the sounds of the city traffic reflecting from the building’s surfaces. His mum let him play in the street because his sound pictures seemed to make him more aware of danger than his sighted friends.

There’s nothing his friends can do that Ben Underwood won't attempt and conquer. Doctors suspect that Ben Underwood has developed super-hearing to make for his loss of sight. However, tests show that he has only normal hearing. So, has Ben’s brain learned to translate the sound he hears into visual information?

1.What is the main idea of the passage?

A. How to see with ears. B. A boy’s poor life without eyes.

C. The way to fight with fate. D. A boy who “sees” without eyes.

2.In what way does Ben have much common with other blind people?

A. He uses a white cane in his everyday life.

B. He takes advantaged of computer software.

C. He feels the same echolocation as others do.

D. He uses his ears instead of his both hands.

3.What does the underlined part mean in Paragraph 3?

A. His eye looked like a ball. B. The doctor stopped their efforts.

C. Nothing really worked. D. His mother was frightened.

4.What can we infer from the passage?

A. The case of Ben has shocked the doctors.

B. The case of Ben is common to children.

C. Quite a few believe what Ben has said.

D. lien does have the super-hearing ability.

From: Lee Haojie

Subject: Handheld Scanners

Ms. Hu, I received the parcel from Scan Technology 1 piece. The scanner model they sent is correct, and the quantity is right. However, I’ve discovered the cables and connectors are all wrong. They are not suitable for the model 8021101.

Can you do me a small favor and go through the product information website and see if the cables and connectors are still compatible (兼容的）with the 8021101 scanners? I have no wish to unpack the cables and connectors and try connecting them to the scanners. I believe we will have problem asking for an exchange if the cables and connectors are not compatible. If the website suggests an incompatibility, please contact Dan Richman and request an exchange for the collect model. (Refer to the invoice for his e-mail address.)

I will only use the scanners for our project once we have resolved the exchange issue. We should not proceed unless we get confirmation (證實）on their compatibility. I am looking to resolve this in the shortest possible time as it would be disastrous to wait for this exchange without making progress on the project.

When it's five o'clock,people leave their office.The length of the workday,for many workers,is defined by time. They leave when the clock tells them they're done.

These days,the time is everywhere: not just on clocks or watches,but on cell-phones and computers.That may be a bad thing,particularly at work.New research shows on that clock-based work schedules hinder morale and creativity.

Clock-timers organize their day by blocks of minutes and hours.For example: a meeting from 9 a.m. to 10 a.m., research from 10 a.m.to noon,etc.On the other hand,task-timers have a list of things they want to accomplish.They work down the list,each task starts when the previous task is completed.It is said that all of us employ a mix of both these types of planning.

What,then,are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier,they had participints organize different activities-from project planning,holiday shopping,to yoga-by time or to-do list to measure how they performed under "clock time" vs "task time".They found clock timers to be more efficient but less happy because they felt little control over their lives.Task timers are happier and more creative,but less productive. They tend to enjoy the moment when something good is happening,and seize opportunities that come up.

The researchers argue that task-based organizing tends to be undervalued and under-supported in the business culture.Smart companies,they believe,will try to bake more task-based planning into their strategies.

This might be a small change to the way we view work and the office,but the researchers argue that it challenges a widespread characteristic of the economy: work organized by clock time.While most people will still probably need,and be,to some extent,clock-timers,task-based timing should be used when performing a job that requires more creativity.It'll make those tasks easier,and the task-doers will be happier.

1.What does the author think of time displayed everywhere?

A. It makes everybody aware of time.

B. It is a convenience for work and life.

C. It may have a negative effect on creative work.

D. It clearly indicates the fast pace of modern life.

2.What did Tamar Avnet and Anne-Laure Sellier find in their experiments about clock-timers ?

A. They seize opportunities as they come up.

B. They always get their work done in time.

C. They have more control over their lives.

D. They tend to be more productive.

3.What do the researchers say about today's business culture?

A. It does not support the strategies adopted by smart companies.

B. It does not attach enough importance to task-based practice.

C. It places more emphasis on work efficiency than on workers’ lives.

D. It aims to bring employees' potential and creativity into full play.

4.What do the researchers suggest?

A. Task-based timing is preferred for doing creative work.

B. It is important to keep a balance between work and life.

C. Performing creative jobs tends to make workers happier.

D. A scientific standard should be adopted in job evaluation.

Once I spoke at a high school. After the speech, I was asked to see a special student. An illness had kept the boy home, but he had expressed an interest in meeting me, and it would mean a great deal to him. I agreed.

He was Matthew. When he was born, the doctor told his parents that he would not live to see five, then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal weight lifter, and I knew about overcoming obstacles(障礙) and going for my dreams.

I spent over an hour talking to Matthew. Never once did he complain. He spoke about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He just talked about his hopes for the future, and how one day he wanted to lift weight with me.

When we finished talking, I went to my briefcase and pulled out the first gold medal I won and put it around his neck. I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment, then took it off and handed it back to me. He said, “You are a champion. You earned that medal. Someday when I get to the Olympics and win my own medal, I will show it to you.”

Last summer I got the news that Matthew had passed away and a letter Matthew had written me a few days before:

Dear Rick,

My mom said I should send you a thank-you letter for the picture you sent me. The doctors tell me that I don’t have long to live any more. But I still smile as much as I can.

I told you some day I was going to the Olympics and win a gold medal. But I know now I’ll never make it. But I know I’m a champion, and God knows that too. When I get to Heaven, God will give me my medal and when you get there, I will show it to you.

Thank you for loving me.

Your friend,

Matthew
