It;s really hard to say,I cant think what I can do today 10 years ago.Now,I can search the bus to somewhere I want to go or book a restaurant by 3g phone when I was in a strange city . I think the web is changing ererything of our life ,and will chang it a lot in furture. I guess the communication will be more convernient , for eg.people could talk with someone come from anywhere by real time translate software; dortors from different countries could do surgical operation out of the operating room ,even at each bathroom. And the important,children could choose what class he/she want to learn and the teacher he/she like and when the class will start,all the things happened at his/her room!

别称 ( some small silly chat of childhood nickname )

昨天 我 在 italki 逢 一个 新 的 朋友.
我们 说话 了. 我 说 了我 的 别称 是 "大 头" ( my cousin called me like this when i was young, huhu, why?, my head isn't that big )
而后 他 称 我 为 "大 魔 头" .(T.T) maybe that's a better name, hix hix
我 称 他 "大 口" hehehe
-------
<strike>当 我 幼稚 </strike>我小的时候, 我 和 我 哥哥 有 一场 大战.
我们 给 <strike>我们 </strike>对方拟 <strike>可恶 </strike>好玩的 别称. haha, oh kids!!!
我 的<strike>可恶</strike>有趣 的 别称 是 "大 头". ( then every people called me that, not only my cousin, huhu ).
我 在 那 场 大战 常 捷, hehe maybe i have a better vivid imagination. :">
some peoples can find our nickname really silly and meaningless, but who cares?, just kids' joke!!! hehe

我 浮想 一 话茬儿 :
<strike>当 我 幼稚</strike>,小时候， 我 学习 很 精干, 不过 我 哥哥 学习....... ( i'm sr, gege, for saying bad things about u, hehe )
他 妈妈<strike> 鞭笞</strike> 教训了他. 她 考问: " 看, 他 ( mean me ) 精干, 你 ( my gege ) 傻, 为什么?"
( ah so shy!!! :">, i'm just telling exactly what my aunt said, not fabricate, hihi :"> )
他 搭白 了: " 因为 他 头 很 大, 他 头 可能 盛 多个 字".
Hahaha, quite a reasonable reason! Haha
------
<strike>当 我 幼稚</strike>,小时候， 我 看 一 中国 的 动画片 " 小头 的 爸爸, 大 头 的 孩子".
太 幸 了 当 我 爸爸 的 头 不 小. hehe
If not, maybe my cousin could have found another cruelly aggressive nickname to call me, hehe!
Xiexie ni, tian a!

Which aspects,I think I like to use italki answer to ask some questions when I meet troubles.We can look Vbs up on Dictionary or internet, and ask our teacher most time,but somequestions our teacher cant tell us ,like um,local oral English,and the most popular phrase or dialog.We can ask from italki,ask our native language partner or native language teacher . The others, notbook can help to improve our writting. ...
