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 the number of your credit card 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（眼睛識(shí)別）program 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.

Eye-recognition is a course of recognizing iris（虹膜）, which includes the following steps. First, a kind of machine needs to collect different examples of one’s iris from his eyes and store them. Second, when this person goes to the bank to take out money, this machine will have iris feature extraction（采集）. Then, this machine will compare the examples kept in it with iris feature extraction. Once the examples and the feature extraction are the same, this person will be identified, and he will take out the money from the bank successfully.

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 now. 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 you in the eye. So smile!

When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect(尊敬) elders. Unluckily, this rule led to my very first embarrassment in the United States.

I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive(敏感) Americans are and how they dislike the description(描述) “old”. I then walked back to the table and apologized（道歉）to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.

In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.

However, in the United States, people think “growing old” is a problem since “old” shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises or jogging, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn’t want to hear.

After that, I changed the way I had been with older people. It is not that I don’t respect them any more; I still respect them, but now I don’t show my feelings through words.

1.Jack brought the couple their food very fast because _______.

A. the manager asked him to do so

B. he respected the elderly

C. the couple wanted him to do so

D. he wanted more pay

2.When Jack called the couple “elderly”, they became _______.

A. nervous B. satisfied

C. unhappy D. excited

3. In Jack’s hometown, _______.

A. people dislike being called “old”

B. people are proud of being old

C. many people reach the age of seventy or eighty

D. the elderly are the first to get food in restaurants

4.After this experience, Jack _______.

A. lost his job in the restaurant

B. made friends with the couple

C. no longer respected the elderly

D. changed his way with older people

5.Which of the following is TRUE?

A. The more Jack explained, the angrier the couple got.

B. Jack wanted to show his feelings through words after his experience.

C. The manager went back to the table and apologized to the couple.

D. From this experience, Jack learned more about American culture.
