What do college students usually do on the saturday night
Twenty years ago,college students listened to the radio,read the poem or write the letter on the saturday night.today,time is getting different for the development of society. Many college students and I usually surf the internet by loptops.You know most of the college students have own their loptops in dorms.
Nowdays,we don't wirte letters by pen yet. Instead,email is more convenient and faster ,
Of course, Sometimes I read something on net.such as the international news,china news ,Especially,I am very interested in military news about the world,But every time,after reading some time on net i will stop and take a rest,or that could do bad to my eyes,so i have to say the internet,so-called high-tech, has both advantages and disadvantages .
Another thing i like to do on net is writting blogs. the blog seems to be like the traditonal diary. Of course there are some differences between them .Generally speaking,the traditional diary is only being read by the owner of it.But the readers of the blog are more wide .for this,many people write their blogs more artistically or cheat in their blogs,so they can get many more others' good comments .for the sake of it,i prefer traditional diary for its simple and true characteristics.
One more thing i like best is to chat with friends online,i think it's familliar for most people to chat with QQ,or MSN,or ICQ,or SKYPE,or UC,or yahoo Messenger and so on and so forth,you know chatting this way is fastest way to communicate with friends,on this apect,it is better than the traditonal letters.
