雅思写作提纲:在公共场合安装监控器(在线收听) |
十五、在公共场合(超市)安装监视器 1、安装监视器的优点:利用监视器可以帮助警察catch criminals,thus reducing crime. a camera is more effective than security guards. 警察和保安不可能全天24小时工作,而camera will not feel tired.而且它更objective,sometimes our eyes might deceive us,while a machine can exactly record what happens,it can prevent much unnecessary embarrassment. Frighten off the criminals and reduce potential crime.
2、缺点:Critiques about installation of surveillance typically look at the infringement of people‘s privacy. Being photographed and recorded by the camera,很多人feel uncomfortable and no privacy.特别是女性,有些人可能会将camera获得的资料用于illegal use.
3、总结:尽管有缺点,但是为了public safety ,监视器是有必要的。但是应该尽可能balance the need for security with respect for individual’s privacy and freedom. |
