Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So 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（眼睛识别 program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology（技术） 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, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs 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.

You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But do you know there is such a thing a “banana person”? How strange! Are these people from “another earth”? No, they are just Chinese people like you and me.
ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a “banana person”. A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside-thinking like a Westerner and yellow outside-looking like a Chinese.
Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don’t speak Chinese. Also, they are not interested in Chinese politics.
But if ABCs can not speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas Chinese (华侨). These people may be citizens (公民) of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are not people of the People’s Republic of China. For example, we all know the famous scientist, C.N.Yang(杨振宁).

On my eighth birthday, Dad bought me an accordion(手风琴） and said excitedly, "Once you learn to play, it'll stay with you for life." But I didn't want to play it. I just wanted to play games, But Dad asked me to take accordion lessons.
One day, I found a box in a corner. When I opened it, I saw a beautiful violin. "It was your father's," Mum said. "His parents bought it for him. I guess he got too busy on the farm to learn to play it."

When the traffic lights turn red, we will stop driving a car or crossing a street. Why is red used for traffic lights instead of other colors?
As we know, scattering (散射) happens when light goes through the air. For the same media (媒质), if the wavelength is long, the sscattering will be short. If the wavelength is short, then the scattering will be long.
Of all lights we can see, red has the longest wavelength. So the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days.
Using the red light can help drivers in farther places see the lights. It helps drivers slow down or stop in time. So there will be fewer accidents. Moreover, red can also excite people. We can act more quickly when we see the color red. In a word, red lights help drivers stop in time and help prevent accidents.According to the passage, the scattering of the red light is the _______.
| A．longest | B．weakest | C．farthest | D．brightest |
The underlined word “wavelength” means________ in Chinese.
| A．光波 | B．波浪 | C．波长 | D．光波 |
What can the red light help drivers do?
| A．It can make drivers stop in time. |
| B．It can help drivers act more slowly. |
| C．It can help drivers see the lights in farther areas . |
| D．A and C |
Which of the following is the best title?
| A．Why do accidents happen |
| B．How does the red light travel |
| C．Why do we use red traffic lights |
| D．The colors of the traffic lights |
