Soon computers and other machines(机器)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 has already been tested in shops and banks in the USA,Britain,Spain,Italy and Turkey.Soon this technology(技术)will take the place of all other ways of finding out who people are.

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/wins 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 at present.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!

Astronauts have already visited the Moon and lived on space stations.They've never been to another planet,but they might visit Mars soon.Astronauts will spend about six months getting to the planet,then about two years on the planet and about six months travelling back to the Earth.They’ll be away from the Earth for about three years,so they'll need much food.

It's very expensive to take food into space.It costs about 120 000 dollars to carry something that weighs(重)one kilo(千克).So an apple on Mars could cost 20000 dollars!

Astronauts on Mars will probably have special machines.They'll use these machines to change beans(豆)into food that tastes like meat or cheese.They probably won't eat real meat or cheese because it won't he possible to keep animals in space.
