希望在你们身上

       ①中国古话说：“长江后浪推前浪，世人新人换旧人。”

       ②人类社会的进步，有如运动场上的接力赛。老年人跑第一棒，中年人跑第二棒，青年人跑第三棒。各有各的长度，各有各的任务，互相协调，共同努力，以期获得最后胜利。这里面并没有高低之分，而只有前后之别。老年人先走，青年人也会变老。如此循环往复，流转不息。这是宇宙和人世间的永恒规律，谁也改变不了一丝一毫。所谓社会的进步，就寓于其中。

       ③这一番道理，虽然老生常谈，然而却是真理。

       ④人世间的真理都是明白易懂的。可是，芸芸众生，花花世界，浑浑噩噩者居多，而明明白白者实少。你们青年人感觉锐敏，英气蓬勃，首先应该认识这个真理。要想树立正确的人生观和价值观，也必须从这里开始。换句话说就是，要认清自己在人类社会进化的漫漫长河中的地位。人类的前途要由你们来决定，祖国的前途要由你们来创造。这就是你们青年人的责任。千万不要把人生观和价值观当作一个哲学命题来讨论，徒托空谈，无补实际。一切人生观和价值观，离开了这个责任感，都是空谈。

       ⑤那么，我作为一个过来人，我不想说些空话、废话、假话、大话，更是一无灵丹妙药，二无锦囊妙计。我只有一点明白易懂简单朴素、又确实是真理的道理。我引一首宋代大儒朱子的一首诗：

少年易老学难成，一寸光阴不可轻。

未觉池塘春草梦，阶前梧叶已秋声。

       ⑥这首诗的关键有二：一是要学习。比如你们对浩如烟海的中华经典必须有深刻的了解。最好能背诵几百首旧诗词和几十篇古文，让它们随时含蕴于你们心中，低吟于你们口头。这对于你们人文素质的提高，都会有极大的好处。二是要惜寸阴。光阴，对青年和老年，都是转瞬即逝，必须爱惜。“一寸光阴一寸金，寸金难买寸光阴”，这是古人留给我们的两句意义深刻的话。

       ⑦对此，你们青年人不仅要心里明白，还要真正能实行，才能接好前人的接力棒，才不会虚度此生。以上都是我的肺腑之谈。

       ⑧青年们，好自为之。世界是你们的。

        As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

       In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood thatthe computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

       In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory (交互记忆)".

       According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.
