Public speaking fills most people with dread. Humiliation is the greatest fear; self-exposure and failing to appeal to the audience come a close second. Women hate it most, since girls are pressurized from an early age to be concerned with appearances of all kinds.

Most people have plenty of insecurities, and this seems like a situation that will bring them out. If parents, teachers or peers mocked your foibles as a child, you fear a repeat. If you were under pressure to be perfect, you are terrified of failing in the most public of ways.

While extroverts will feel less fear before the ordeal, it does not mean they will necessarily do it better. Some very shy people manage to shine. In fact, personality is not the best predictor of who does it well. Regardless of what you are like in real life, the key seems to be to act yourself.

Actual acting, as in performing the scripted lines of a character other than yourself, does not do the job. While politicians may limit damage by having carefully rehearsed, written screeds to speak from, there is always a hidden awareness among the audience that the words might not be true.

Although, as Earl Spencer proved at his sister Princess Diana’s funeral, it is possible both to prepare every word and to act naturally, a script rarely works and it is used as a crutch by most people. But, being yourself doesn’t work either. If you spoke as if you were in your own kitchen, it would be too authentic, too unaware of the need to communicate with an audience.

I remember going to see British psychiatrist RD Laing speak in public. He behaved like a seriously odd person, talking off the top of his head. Although he was talking about madness and he wrote on mental illness, he seemed to be exhibiting rather than explaining it.

The best psychological place from which to speak is an unselfconscious self-consciousness, providing the illusion of being natural. Studies suggest that this state of "flow", as psychologists call it, is very satisfying. Whether in normal life or making speeches, the key is to remind yourself that, contrary to what your teachers or parents may have implied, your best is good enough. In the zone, a strange place of authentic falsehood and shallow depth, play is possible.

For most people the biggest fear for public speaking is ().

A. looking foolish

B. failing in words

C. not attracting attention

D. appearing pressurized

无畏创造奇迹

江玲

  1796年的一天,在德国哥廷根大学,一个19岁的青年吃完晚饭,开始做导师单独布置给他的每天例行的两道数学题。

  青年很有数学天赋,正常情况下,他总是在两个小时内完成这项特殊作业。

  “咦,怎么今天导师给我多布置了一道?”青年一边打开写着题目的纸,一边咕哝着。他也没多想,就做了起来。

  像往常一样,前两道题目在两个小时内顺利地完成了。第三道题写在一张小纸条上,是要求只用圆规和一把没有刻度的直尺做出正十七边形。青年没有在意,像做前两道题一样开始做起来。然而,做着做着,青年感到越来越吃力。开始,他还想,也许导师见我每天的题目都做得很顺利,这次特意给我增加难度吧。但是,随着时间一分一秒地过去,第三道题竟毫无进展。青年绞尽脑汁,也想不出现有的数学知识对解开这道题有什么帮助。

  困难激起了青年的斗志:我一定要把它做出来!他拿着圆规和直尺,在纸上画着,尝试着用一些超常规的思路去解这道题……终于,当窗口露出一丝亮色时,青年长舒了一口气,他终于做出了这道难题……

  见到导师时,青年感到有些内疚和自责。他对导师说:“您给我布置的第三道题我做了整整一个通宵,我辜负了您对我的栽培……”

  导师接过青年的作业一看,当即惊呆了。他用颤抖的声音对青年说:“这真是你自己做出来的?”青年有些疑惑地看着激动不已的导师,回答道:“当然,但是,我很笨,竟然花了整整一个通宵才做出来。”导师请青年坐下,取出圆规和直尺,在书桌上铺开纸,叫青年当着他的面做一个正十七边形。

  青年很快做出下一个正十七边形。导师激动地对青年说:“你知不知道,你解开了一道有2000年历史的数学悬案?阿基米德没有解出来,牛顿也没有解出来,你竟然一个晚上就解出来了,你真是天才!我最近正在研究这道题,昨天给你布置题目时,不小心把写有这道题目的小纸条夹在了给你的题目里。”

  多年以后,这个青年回忆起这一幕时,总是说:如果有人告诉我,这是一道有2000多年历史的数学难题,我不可能在一个晚上解决它。

  这个青年就是数学王子高斯。

  有些事在不清楚它到底有多难时,我们往往能做得更好,这就是人们常说的无知者无畏。

1.文章中找出一些描述第三道题非常难的语句。

___________________________________________________

2.有人认为在碰到困难时应坚持不懈,但也有人认为遇到困难应及时寻求适当的帮助,否则就会钻牛角尖而不可自拔,造成不必要的时间和精力的浪费,对此你怎样认为?

___________________________________________________

3.这篇文章直到最后才点明画正十七边形的难题是有2000年历史的数学悬案,也直到最后才点明这个青年是数学王子高斯,你觉得这样安排文章结构好吗?为什么?

___________________________________________________

4.这篇文章从高斯的故事中概括出“无知者无畏”这样具有哲理性的话语,试用同样的方法为下面一首诗概括一句话,字数不限。

题西陵壁

宋·苏轼

横看成岭侧成峰,

远近高低各不同。

不识庐山真面目,

只缘身在此山中。
