Topic:Nowadays,people in some countries can choose to live and work anywhere they want,because of the improvement of the communication technology and transport.Discuss both the advantages and disadvantages.
In many parts of the world,it is quite common these day for people to do almost everything by state-of-the-art facility,such as chat,business trip,learning and so on.The trend is not restricted to the rich who have money to use,but is also evident among the poor who choose to buy because of convenient.
Firstly,the reasons for this trend may involve the recognition that people who do not have communication technology,like mobile phone is rather restricted in term of the convenience of communication anytime,anywhere.By contrast,those who have already own one could contact with his family at once when they are away from home.
Another advantage of using transport and technology is that people could save more time.It is inconceivable that people who live in Asia want to go to Europe by foot.But now,they can choose plane instead,it will cost only several hours.Similarly,some people may take a long time to go to school.Why do they study on the Internet?They can just sit in front of the computer,then learn what they what to learn.
However,the following facts would show a radical different picture.Cell phone,computers and other electronic products will make radiation,and it will be harmful to people's healthy.Research has been providing evidence that people who often travel by plane is more likely to develop cancer disease,because they exposure among the radiation prolonged.
So overall,the advantage of using those outweigh the disadvantages,I believe that people should be encouraged to use the communication technology and transport,those would help people make effective and efficient use of time and money.
