閱讀下面短文,根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容摘要。
With the development of the computer,virtual reality(虛擬現(xiàn)實(shí))steps in our life.If something is virtual,then it is created by computer technology and appears as if it were real.VR is a computer system with a special headset(耳機(jī)).When you put on the headset,you will look at two tiny television screens.They are so close to your eyes as if you see just one picture and you will believe that you have entered a different world.In many systems,you also wear special gloves.With the gloves you can reach out and touch things in the unreal world.
The first VR games,which have already been sold round the world,enable you to drive a sports car,fly a plane,or fight an enemy.In the future,it may be difficult to tell the virtual world of the games from the real world outside.However,VR is not just for entertainment.One day,delighted children will be able to learn geography by observing exciting foreign countries without having to leave their classrooms.They will be excited to learn history by visiting the pyramids of Egypt.In addition,businesses will be able to use VR for many tasks.Pilots will be able to practise flying virtual planes before they go into the air.VR can help us improve the world in hundreds of ways.
However,some people have warned that there could be dangers.It might be dangerous if we do something wrong,or if people do not want to return to reality because it is safer than real life.Besides,we will forget how to live and work with real people.
There will be some problems with VR,as it is new for us.However,one thing is for sure:VR is here to stay.Get ready to step into another world!
