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 a 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 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 have already had 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 at you in the eye，So smile!

阅读下面语言材料，根据要求作答。根据短文内容，判断文后句子的正确(T)与错误（F）
“How are you?” is a nice question. It’s a friendly way that people in the U.S.A greet each other. But “How are you?” is also a very unusual question. It’s a question that often doesn’t need an answer. The person who asks“ How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine” isn’t really an answer. They are simply other ways of saying “Hello” or “Hi”.
Sometimes, people also don’t say exactly what they mean. For example, when someone Asks “Do you agree?”, the other person might think, “No, I disagree. I think you’re Wrong...”But it isn’t very polite to disagree so strongly, so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.
People also don’t say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person say “I’ve to go now.” Often, the person who wants to hang up gives an excuse: “Someone’s at the door.”“Something is burning on the stove.” The excuses might be real, or not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt the other person.
Whether they are greeting each other, talking about an idea, or finishing a talk, people don’t say exactly that they are thinking. It’s an important way that people try to be nice to each other, and it’s part of the game of language.“How are you?” is another way of saying "Hello." or" Hi."
It is polite to say" No. I disagree I think you are wrong, "if you don’t agree with others.
When someone says "I have to go now "On the phone.it means he wants to go on talking.
"Someone is at the door." may be an excuse for finishing a phone.
Sometimes people don’t say exactly what they are thinking about just because they try to be nice to each other.
