Public Speaking and Critical thinkingWhat is critical thinking? To a certain degree, it's a matter of logic -- 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. ___. The greatest thinkers, scientists, and inventors have often taken information that was really available and put it together differently to produce new ideas.That, too, is critical thinking.
__ _. 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. ____.
What is true of organization is true of many aspects of public speaking. ____. As you work on expressing your ideas in clear accurate language, you will improve your ability to think clearly and accurately. __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 take 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. 题型：未知难度：其他题型

例：one→first
two→second
three→third
five→fifth
eight→eighth
nine→ninth
twelve→twelfth
③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。
例：twenty→twentieth
thirty→thirtieth
forty→fortieth
ninety→ninetieth
④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。
例：twenty－one→twenty－first
thirty－five→thirty－fifth
a hundred and fifty－three→a hundred and fifty－third
2、序数词的用法：
①序数词在使用时，一般加上定冠词。

1）分数词构成法：
分数词（FractionalNumerals）由基数词和序数词构成，基数词代表分子，序数词代表分母。除了分子为1的情况下，序数词都要用复数形式：
如：1/4：one-fourth
5/9：five-ninths
2/3：two-thirds
17/5：three and two-fifths
7/12：seven-twelfths
379/8：forty-seven and three-eighths
