雅思写作例文之科技发展

浏览: 来源:互联网

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

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

  Some of the most obvious problems caused by technological advances lie inthe IT industry. At a time when we did not have computers and electronic bankservices, 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 morecommonly used in shopping malls and other places, crimes again us have becomemore serious and caused greater losses to people. A thief may tape the code ofyour credit card and make a copy of it. Then he could safely withdraw all yourmoney from an ATM machine. Crimes such as this are very sticky to solve becausethere is no witness and the surveillance cameras give little help to thepolice.

  Another example is the issue of information control with the media industryincluding TV networks and Internet that give easy access to information withoutdiscrimination to people’s age. This has created a huge problem for parents andschools because teenage people are particularly vulnerable to adult materialsand information violent in nature. In the past, when most information came inthe form of print, it was relatively easy to control what children read. When aparent put away a book unsuitable for children, they were cut off from thesource of information. With computer parents could use software to filter badweb sites but could not prevent new ones from appearing every day.
