Barefoot and dirty, the girl just sat and watched the people go by. She never tried to speak. Many people

The next day I decided to go back to the park, being curious if the little girl would still be there. Right in the very spot as she was yesterday, she sat, with the look on her face.

As I began walking towards her, I could see the back of the little girl's dress which showed a deformity(畸形). As I got closer, the little girl slightly lowered her eyes to my eyes.

I sat down beside her and opened with a simple . The little girl stammered(结结巴巴地说) a hi. I smiled and she shyly smiled back. We talked until darkness fell and the park was completely empty.

"Why are you so sad?"

She replied slowly, "Because I'm "Little girl," I said in a soft voice, "You me of an angel because of your difference." She stood to her feet excitedly, "Really?"

"Yes, that's the thing. You're like a little angel sent to watch over all those people walking by." She nodded her head and smiled, " I am. And since you think of someone

yourself, my job here is done."

What a big surprise! I asked quickly, "Wait, so why did no one stop to help an angel?"

She bloomed(绽放) a big smile, "You are the one who could see me, because you care for others." With those words, she spread her wings and flew away from my sight.

From then on, I believe I am not all I have, for there is an angel always me. She is always watching over those who do good things for others.

If you want to see a thing well, touching can help you to "see" it better.

Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass ball is. When you learn all about the ball, you really see it well.

With your skin, you can feel better. For example, your fingers can tell the difference between two different coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.

All children soon learn what "Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things that we might buy. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.

Most museums are just for looking. But today some museums have some things to touch. Their signs say, "Do touch!" There you can feel everything on show.

There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin.

If you want to see better, reach out and touch. Then you will really see!

25.The underlined word "these" in Paragraph 2 refers to________.

A. a glass ball is round

B. a glass ball is smooth and cool

C. a glass ball is smooth, cool and heavy

D. a glass ball is round, smooth, cool and heavy

26.Which of the following is NOT true?

A. People don't have to learn to feel.

B. Our skin may help us enjoy music.

C. By touching things, we can learn more about them.

D. We have to touch something in order to see it well.

27.________ can be the best title of the passage.

A. Feeling by Seeing B. To See or to Feel

C. To See Better---Touch D. Ways of Touching

B

Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone's eyes are different. Therefore, in the future you won't have to remember a number when you want to use a machine or take money out of a bank. You'll just have to look at the machine and it will be able to tell who you are.

The eye-recognition programme has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology will take the place of all other ways of finding out who people are.

However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.

Eye-recognition is better than other kinds because your eyes don't change as you get older, a(转自:wWw.DXf5.Com 东星 资源网:南菁高中中考分数线)nd don't get dirty like hands or fingers, and even twins have different eyes. The eye-recognition programme can be up to 94% correct, depending on how good the technology is. However, some other programmes may only be 51% correct at present. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.

In the future your computer will be looking at you in the eye. So smile!

28.Where has the eye-recognition programme already been tested in a few countries?

A. In shops and banks.B. In shops and schools.

C. In banks and schools. D. In schools and hospitals.

29.We already have machines that can tell who you are from________.

A. your eyes or your smell

B. your voice or the mark by your finger

C. your face or your voice

D. your face or your hand

30.Which of the following doesn't belong to the advantages of the eye-recognition programme?
