                                                    Public Speaking and Critical thinking

     What is critical thinking? To a certain degree, It's a matter of logic (逻辑)-of being able to spot

weakness in other people's arguments and to avoid them in your own. It also includes related skills such

as distinguishing fact from opinion and assessing the soundness of evidence. In the broad sense, critical

thinking is focused, organized thinking-the ability to see clearly the relationships among ideas. 1_____ the

greatest thinkers, scientists, and inventors have often taken information that was really available and put

it together differently to produce new ideas. That was readily available and put it together differently to

produce new ideas. That, too, is critical thinking. 

     2_____ As the class goes on, for example, you will probably spend a good deal of time organizing

your speeches. While this may seem like a purely mechanical (机械的) exercise, it is closely connected

with critical thinking. If the structure of your speech is loose and confused, chances are that your

thinking is also disordered and confused. If, on the other hand, the structure is clear, there is a good chance

your thinking is too. Organizing a speech is not just a matter of arranging your ideas you already have.

3_____

     What is true of organization is true of many aspects of public speaking. 4_____. As you work on

expressing your ideas in clear accurate language, you will improve your ability to think clearly and accurately.

5_____ As you learn to listen critically to speeches in class, you will be better able to assess the ideas of

speakers in a variety of situations.

     If you take full advantage of your speech class, you will be able to develop your skills as a critical

thinker in many circumstances. This is one reason public speaking has been regarded as a vital part of

education since the days of ancient Greece.

A. Rather, it is an important part of shaping the ideas themselves.

B. This may seem like a lot of time, but the rewards are well worth it.

C. It may also help you to know that there is no such thing as a perfect speech.

D. It has often been said that there are few new ideas in the world, only reorganized ideas.

E. If you are wondering what this has to do with your public speaking class, the answer is quite a lot.

F. The skills you learn in your speech class can help you become a more effective thinker in a number 

    of ways.

G. As you study the role of evidence and reasoning in speechmaking,you will see how they can be used

     in other forms of communication as well.
