Perhaps the technology that exerts the most profound influence to people’s lives is internet. Through internet we can work, study, entertain, order food and any other commodity, without actually going to the workplaces, schools, cinemas and shops. In a word, technology progress has brought a lot of benefits to us. However, we can’t neglect the fact that it also does harm to our lives. For example, spending too much on internet results in people’s laziness, reduces people’s chance of face to to face communication and is harmful to people’s health.
