Public Speaking Training

Get a coach

 小题1: , so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that’s right for you.

Focus on positives

Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren’t doing well.   小题2:  , so good public speaking training should develop those instead of telling you what you shouldn’t do.

  小题3: 

If you find a public speaking course that looks as though it’s going to give you lots of dos and don’ts, walk away! Your brain is so full of what you’re going to be talking about. 小题4:   . As far as we’re concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.

You are a special person not a clone.

Most importantly, good public speaking training should treat you as a special one, with your own personal habits.   小题5:   . Your training course should help you bring out your personality, not try to turn you into someone you’re not.

A.You aren’t like anybody else

B.You already do lots of things well

C.Turn your back on too many rules

D.Check the rules about dos and don’tsE.Whatever the presentation, public speaking is tough

F.The one thing you don’t want is for them to fall asleep

G.So trying to force a whole set of rules into it will just make things worse

  马是人类的朋友,它曾经留给我们弥足珍贵的记忆。现在,让我们走进综合性学习实践活动,进行一次有趣的探究。

(1)下面是一则小故事,请给它拟个标题,并说说故事寓意。

  伯乐推荐九方皋为秦穆公选马。三个月后,九方皋返回,说已经如愿以偿了。穆公问是什么样的马。九方皋说是黄色的母马。可是取回的却是一只纯黑色的公马。秦穆公很不高兴,召见伯乐,对他说:“你推荐的人,连马的颜色和雌雄都不能识别,又怎么能识别千里马呢?”伯乐说:“这就是千万个我比不上九方皋的原因。九方皋所看见的马的是内在素质,而马的外表他都一一忽略。”穆公骑上马一试,果然是一匹千里马。
