【推荐2】Soon computers and other machines will be able to remember you by looking at your eyes. The programme works because everyone’s eyes are     1    . So in the future you won’t have to remember a group of numbers 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 you who you are.

The eye-recognition(眼睛识别) programme has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon it will take the place of all other ways of     2     out who people are. However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hand or     3     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     4    like hands or fingers. And twins’ eyes are not the same. So the eye-recognition programme can be up to 94 percent correct. In Britain, it was found that 91 percent of the people who had     5     it said that they liked the idea of eye-recognition.

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