Public Speaking and Critical Thinking

What is critical thinking？To a certain degree，it's a matter of logic(邏輯)—of being able to spot weaknesses 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 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(機(jī)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 the 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 approve 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.

【試題分析】本文是議論文。從廣義上說，批判性思維是一種條理性的思維方式，一種能夠看到各種觀點(diǎn)之間聯(lián)系的能力。本文作者以組織演講為例，說明批判性思維的具體表現(xiàn)形式。

1．解析：細(xì)節(jié)過渡題。根據(jù)下文中的“The greatest thinkers，scientists，and inventors have often taken information that was readily available and put it together differently to produce new ideas.”可知，世界上沒有新的思想，只有重組后的新思想。

答案：D

2．解析：主旨大意題。文章下文是批判性思維和演講的關(guān)系，故E項(xiàng)為該段的段落主題句。

答案：E

3．解析：段落結(jié)論題。此空和上句是本段的段落結(jié)論，組織演講不只是安排你已經(jīng)擁有的想法，而是重塑思想的重要部分。

答案：A

4．解析：細(xì)節(jié)過渡題。在演講課上學(xué)習(xí)到的技能在許多方面使你成為優(yōu)秀的思想者，此處是總述，下文通過幾個并列句進(jìn)行分述，其實(shí)是對段落主題句的照應(yīng)。

答案：F

5．解析：文章結(jié)構(gòu)題。此空上下文都出現(xiàn)了as引導(dǎo)的時間狀語從句，以說明演講課程的好處，這樣G項(xiàng)在結(jié)構(gòu)和語境兩方面都很吻合。

答案：G
