4.16 Telephones have had more positive effects on human kind than televisions
A little question :50分钟,,,如何保证写作的时间限制在30分钟以内,而不影响质量?
Since the electromagnetic wave has firstly been proved existent and applied into radio communication, the era of information explosion is getting underway. Telephones and televisions are both the most influential inventions for all of us. However, as the old saying goes, every coin has two sides, most inventions have also negative effects on human, when we are enjoying the convenience and benefits they give to us. In terms of telephones and television, I think both of them have positive and negative effects in different aspects, which could not be measured which one is more positive. My postion is illustrated as following.
Firstly, most of people think the television has a number of negative effects on people, especially for children, because it is harmful for our fitness and health. More children nowadays are short-sighted and wearing glasses, since they are watching too much TV. Also people are now over weight because lack of outdoor exercises. Instead they spend most time on watching TV in the sofa. In other cases, however, televisions indeed give us a lot of entertainment, as well as other benefits. For instance, it broaden our eyes that we can see lots of news happening in the other side of the world. This small television box supports a huge production chain, job opportunities and media market, like advertising, football game rebroadcasting, and so on. What is more, TV set has also improved our nations more democratic, because the policy is more transparent for folk people. All in all, television has both negative and positive effects that we can not decide which is overweight.
Secondly, when we are astonished by the supor convinience that telephones have brought to us, only a few people might think telephones have also negative effects on us. As the same way as the television indirectly harms our physical health, scientists have always been researching the negative influence of the electromagnetic radiation by cell phones on our brain, and it does have some researching results indicates a negative effect. In other cases, when we are enjoying the convenience that chatting on phone at any time and anywhere, more or less we lose the happiness of face to face talk, with our relatives and friends. In order to improve the effeciency of working, tons of messages and missed calls are flowing to us in our sleeping time or leisure time. Sometimes it is hard to make your phones be off for a few time in one day. Thus, considering with those changes of life telephones brought us, we cannot guarrantee that the telephones are more positive or negative to our health and life.
In sum, according to the analysis above, we can draw a conclusion that we should not be so serious about which invention is more positive or negative on human, but both of them have their own advantages and disadvantages. |
