   雅思范文-科技發(fā)展與其問題 
  來源:美味英語俱樂部


    Scientific and technological advances have changed our lives. But some scientists in some fields say that scientists are not able to find solutions to the problems they have created. To what extent do you agree or disagree?


    We sure live differently from our parents did decades ago. The changes are wide and profound. At the same time, we are facing challenges and problems unknown in the past. Could we find solutions to problems created by scientific development? The answer seems to be no. 

    Some of the most obvious problems caused by technological advances lie in the IT industry. At a time when we did not have computers and electronic bank services, people took money with them and paid by cash. If they were stolen, only the amount they had with them was lost. But now credit cards are more commonly used in shopping malls and other places, crimes again us have become more serious and caused greater losses to people. A thief may tape the code of your credit card and make a copy of it. Then he could safely withdraw all your money from an ATM machine. Crimes such as this are very sticky to solve because there is no witness and the surveillance cameras give little help to the police. 

    Another example is the issue of information control with the media industry including TV networks and Internet that give easy access to information without discrimination to people’s age. This has created a huge problem for parents and schools because teenage people are particularly vulnerable to adult materials and information violent in nature. In the past, when most information came in the form of print, it was relatively easy to control what children read. When a parent put away a book unsuitable for children, they were cut off from the source of information. With computer parents could use software to filter bad web sites but could not prevent new ones from appearing every day. 

    People are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. Even with the little progress we have achieved, we find ourselves defeated by new problems with greater complexity and in wider scope. 

    In conclusion, developments in many fields of our life have brought us both benefits and problems. Developments in the banking industry give us greater convenience but making us targets of computer-based theft. Changes in media industry expose young people to inappropriate information difficult for parent’s control. However up until now, we have not successfully found permanent solutions yet.
