e: Social networking services are good for society. ソーシャル・ネットワーキング・サービスは社会にとって有益である、という意見に賛成か、反対か? Threre have been a lot of discussions and debates about social networking services. Personally, I disagree with the idea that they are good for society. First, these days crimes related to social networking services have been increasing. This is a result that people disclose their personal information on the services without hesitation. Therefore, the more crimes would happen, if the more often people come to use them. Second, too much of use of them might reduce productivity. Not a few people connot stop thinking of them even when they are working at their workpleces. This might be a cause of less productivity of their companies. In conclusion, for these two reasons, increas of crimes and less productivity, I disagree with the idea that social networking services are good for society. (137words) 構成4/4 内容4/4 文法4/4 語彙4/4
