The globe is becoming smaller and smaller because of the Internet. On the one hand, people can not only correspond but also have conferences with their colleagues far away online. Students can also get accurate reference from educators, while customers can find abundant brands of clothes online to choose from. On the other hand, people may get bothered by diverse relevant sources. They have to comb through and classify them, evaluating and abandoning false information.

　　由于互联网，世界正变得越来越小。一方面人们不仅可以在网上和远方的同事通信，还可以开会。学生们也可以从教育家那里得到精准的征询，而顾客也可以在网上找到大量品牌的衣服以供选择。另一方面，人们会被各种各样的相关信息源搞得心烦。他们不得不对此认真浏览和分类，评估并摒弃虚假信息。
