1 . 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 is already being tested in shops and banks in the USA, Britain and France. Soon, this technology (技术) will change all other ways of finding 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 hands or even your smell! We already have machines that can tell who you are from your voice or the mark made by your fingers.
Eye-recognition is better than other kinds 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 program can be up to 94％ correct, depending on (依靠) how good the technology is. Some programs may only be right 51％ of the time. 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!

A science fiction flying car looks like a normal car, but it is an aircraft (飞行器) that anybody can fly directly from any place to another without using roads or runways. Science fiction writers have written about flying cars for a long time. But now flying cars will soon fly out of the world of science fiction into our real world. And the dream of the science fiction writers will soon come true.
The first-known sky car is the FSC-1. The FSC-1 looks like an expensive sports car. You can drive the FSC-1 on the road like a normal car. If you touch a button, its wings and propeller (螺旋桨) fold out and then it can take off, fly and land as an airplane. The owners of the FSC-1 can choose if they want to drive or fly.
Another flying car or sky car is the Moller Skycar M400. Although you can’t drive it on the roads, it is small and easy to fly and can take off and land like a helicopter (直升飞机). Urban Aeronautics’ X-Hawk is another type of sky car. It is expected to be available for about $3 million.
Just like any new technology, flying cars have taken a long time to be developed. But some experts think the technology is far from what people imagine when they are sitting in traffic. It still needs to be improved.
