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（識(shí)別）programme is already being 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．
   However，scientists are 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，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．Some programmes 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!

3．Can anyone be an astronaut？
   Of course not.You don't have to have a science degree but most astronauts do.Most of them are pilots too.Life in a spaceship is hard so you must have a healthy body and mind.You need to be easy-going，patient，and helpful to spend so much time in a small space with other people.
   What's the training like？
   People have to train for a year to learn how to stay healthy and safe.They practise space walking and living in zero gravity（重力）.They train in difficult conditions to learn how to solve problems and to work in a team.Everyday tasks like eating，washing and sleeping can be difficult on a spaceship.There is no running water so you have to wash with wet tissues：it's hard to enjoy the dry food that astronauts have to eat.And to sleep you must cover your eyes because the sun rises every 90 minutes on the International Space Station.You also have to tie yourself to something so you don't fly away!
   What health problems do astronauts have？
   Life in zero gravity causes changes to our bodies.Bones and muscles（肌肉）become thin and weak so you must do a lot of exercise in space to stay fit and to help the heart move blood around your body.Astronauts often get backache because you grow in space— up to 8 centimeters!It's also common to have headaches and to feel sick，especially at the beginning.You must have vitamins to take the place of fresh fruit and vegetables.But you don't have to put on sun cream because space suits can protect your skin （皮膚）.
   Are you still interested？
（1）What is a must for an astronaut？

A．A science degree.
B．A pilot's license.
C．A healthy body and mind.
D．A weak character.
（2）What must you do to prepare for a space trip？

A．Experience zero gravity.
B．Wash with running water.
C．Practise long walks.
D．Sleep with your eyes open.
（3）Why do astronauts have to exercise in space？

A．To make their bones and muscles thinner.
B．To help the heart work well and keep fit.
C．To avoid backache and grow much taller.
D．To stop their skins from getting sunburned.
（4）What is the text maily about？

A．What we need to know to become an astronaut.
B．Why young people are interested in space trips？
C．What problems astronauts must solve in space.
D．Why we need to train hard before a space trip.
