求翻译：我的姐姐，现在在清华大学读医学系，他的工作很多，还要查许许多多的资料。如果他查资料时，不上网，而要在图书馆里找得眼花缭乱，手抄文字到抽筋，请问：现在是不是网上冲浪对我们有利？是什么意思？

My sister, now read at Tsinghua University Department of Medicine, his work a lot, but also check many of the data. If he check the data, Internet, and in the library to find a dazzling, hand-written text to cramp, I ask you: now is not the surf is good for us?
