电脑比我们更聪明吗？
P4
这个问题的答案是“不”。随着时间推移你的大脑可以 产生新的想法但电脑不行。然而， 有朝一日电脑可能可
以把一些人类能做的工作做得更好。比如， 它们可能比
人类更胜任医生这类工作。zxXK
如果电脑能做所有我们会做的事，将会发生什么呢？我 们将什么也做不了吗？电脑也许会改变我们的生活，但它 P5 们会使生活变得更好？
•1、书籍是朋友,虽然没有热情,但是非常忠实。2022年4月22日星期五2022/4/222022/4/222022/4/22 •2、科学的灵感，决不是坐等可以等来的。如果说，科学上的发现有什么偶然的机遇的话，那么这种‘偶然的机遇’只能给那些学有素养的人，给那些善于 独立思考的人，给那些具有锲而不舍的人。2022年4月2022/4/222022/4/222022/4/224/22/2022 •3、书籍—通过心灵观察世界的窗口.住宅里没有书,犹如房间里没有窗户。2022/4/222022/4/22April 22, 2022

越来越小，越来越好电脑 NhomakorabeaP1
第一台电脑诞生于20世纪40年代，那时它们比汽 车还大。而现在，电脑变得越来越小。
有些电脑非常小。以至于你也许没意识到它们。或 P2 许它们在你的电视机里，电话机里或洗衣机里。所
以你对电脑的依赖超出了你的意识。
我们能用电脑做什么？
P3 我们可以用电脑来计算。它们能比我们计 算的更快，而且几乎从不出错。我们还可 以用电脑来打字和画画。除此之外，电脑 还可以做一些重要的工作，比如操控铁路 系统，驾驶飞机和宇宙飞船。
谢谢观赏
