Question: If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and this is because of their bad eating habits. Most teenagers are fond of food with a lot of fat, oil, salt and sugar. People call this kind of food "junk food". But bad eating habits go beyond fast food. We find many teenagers eat unhealthily.

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. 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  programme is tested in shops and banks in the USA, Britain and Italy. Scientists are working on other systems, such as knowing you from the shape of your face or hand or even your smell! And machines can already tell who you are from your voice or your fingerprint . But eye-recognition will replace other ways of finding out who you are. It is better, because your eyes don't change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94% correct, depending on how good the technology is. In Britain, it was found that 91% of people said that they liked the idea of eye-recognition. ,. What problems could there be with the eye-recognition programme? A) Some eyes are the same. B) Eyes can change. C) It is not always correct. D) Eyes can get dirty.
