I think surfing the Internet is good and bad.
The Internet can help our learning and life,for example:we learn at school,according to the book,is far from enough,then we can access the net to look up the material,learning will be more comprehensive; also,the adults work sometimes need to write some of the information,may be a few copies of the same,if you use a few hours handwriting need to write a good,and even a few days,but the computer typing more quickly,if more than a few copies also no problem.From the point of view,our life is inseparable from the computer,also can not get away from the internet.
Of course,the Internet also has not the good place,if you play computer games,and less time to play nothing,but when playing a long time,addicted,it may affect the study and health of body and mind,also easy to myopia,but is not good!
Internet has its advantages and disadvantages,but the Internet much always short-sighted,so students will be as little as possible online oh!
我认为上网有好也有坏.
上网可以有利于我们的学习和生活,比如：我们在学校学习,照着书本学,是远远不够的,这时我们便可以上网查些资料,学习的就会更全面；还有,大人上班有时会需要写一些资料,可能还要几份相同的,如果用手写需要写上好几个小时,甚至几天,但是用电脑打字就快多了,假如要多几份复印也没问题.从这几点看,我们的生活是离不开电脑,也离不开上网.
当然上网也有不好的地方,假如你爱玩电脑游戏,玩的时间少没啥关系,可一旦玩的时间长了,上了瘾,有可能会影响学习和身心健康,还容易近视,可不好呀!
上网有利也有弊,不过上网多了总是要近视的,所以同学们要尽量少上网哦!
