Modern scientists have mad great development in building computers that can imitate logical thought. There are two schools of thought on artificial intelligence(人工智能)。 Supporters of “Strong AI” consider that all human thought can be broken down into a set of mathematical operations. They expect that they will one day be able to copy the human mind and create a robot able to both think and feel, with a sense of self---the stuff of classic science fiction. Supporters of “Weak AI” think a computer might seem intelligent, but it is not aware of what it is doing, with no sense of self or consciousness.

Now the development of life---like robots may be closer to reality than you think. Engineers have created robotic soccer players, and bees that act like the real thing.

Powered by a small battery on her back, humanoid robot Lola is a soccer champion. “The idea of the robot is that it can walk and see things because it has a video camera on top.” Raul Rojas, Ph.D., professor of artificial intelligence at Freie University in Berlin, Germany, told Ivanhoe. Using the camera on her head, Lola recognizes objects by color.

“Using this camera, Lola can locate objects on the floor, such as a red ball, go after the ball and try to score a goal,” said Dr. Rojas. German engineers have also created a bee robot. It can imitate the bee’s “waggle” dance which communicates the location of food and water.

“Later what we want to prove is that the robot can send the bees in any decided direction using the waggle dance,” said Dr. Rojas.

Robots like this could one day become high-tech surveillance(侦察) tools that secretly fly and record data.

64. Robotic soccer players mentioned in the text reach the level of        .

A. “Strong AI” technology        B. “Weak AI” technology

C. being able to think themselves  D. having a sense of consciousness

65. How does Lola tell different objects according to the text?

A. By microwave   B. By sound    C. By smell.   D. By color

66. The underlined word “this” in the last paragraph refers to “      ”.

A. a bee robot                       B. a robotic soccer player

C. a bee that can use the waggle dance  D. a surveillance tool

67. Which of the following statements is TRUE according to the text?

A. A robot able to both think and feel only exists in science fiction now.

B. Scientists have created the robots that can play soccer better than men.

C. Engineers have created robotic soccer players and bees that can replace the real thing,

D. Scientists have made great development in recording data in the past few years.

用心脏生活  我一直反对用成熟或幼稚之类的词汇来衡量一个人的进步程度,因为这是一种基于大众准则的理性判断,并不能涵盖一种更接近诗意的生存。  我20岁左右的时候,经常因为过于率真浪漫而在为人处世上发生事故,所以便用法国著名风景画家柯罗来抵挡别人对自己许多可笑举止的嘲笑。因为那么伟大的柯罗,对社会常识依旧知之甚少,以致父母从不放心他一个人单独出门,他五十多岁了外出还必须向母亲请假。  柯罗的幼稚也许是因为他沉醉于对美的探索而忽略了对生活技能的演练。可以相信的是,他在画布上从不会迷路,并因此比那些成熟的人领略到了更多的人生辉煌。  还有另一种人的不成熟,是因为无法学会和适应流行的价值准则。他们是时代的水土不服者,或者说,他们眼里根本就没有那些公共绿地上的栅栏,孤独的身影骄傲地掠过人群的尖叫和愤怒。  曾读过一个故事:一个欧洲商人在太平洋的一座小岛上发现一个老者手编的草帽很漂亮,每只售价20比索。商人想倒一些到欧洲去卖,便问老者:如果一次买一万顶,每顶可以便宜多少?老者却答:每顶还要多加10比索,因为编一万顶相同的帽子会让我乏味而死。  我真是爱极了这个老人,他用近乎天籁的声音,对自以为是的商业法则说了一声"不"。能列出的前辈还有许多。他们飞行在芸芸众生的头顶,相似的身影重叠在一起,成为我的精神教父,鼓励我在森林之外长成一棵独特的树--不计后果地爱,绝不含糊地恨。到了30岁还相信光荣与梦想。  有一种人,他取舍生活的主要依据不是得与失,甚至不是世俗意义上的对与错,人生指南里只有美与丑、泪水或者麻木之类的路标。他们不一定能抵达所谓的成功,但胸腔里永远装满了感动与幸福。  他们和人群最大的区别在于:人们习惯用大脑指导人生,而他们,更喜欢用心脏生活。

文中卖手编草帽的老者那番话想说明什么问题?(2分)
