When a starving man gets a meal, he begins to think about an overcoat; when an executive gets a new sports car, visions of country clubs and pleasure beats dance into view.
The many wants of mankind might be regarded as making up several levels. .
The first and most basic level of wants involves food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. It included such items as automobiles and new houses.
By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels involve physical satisfaction－the feeding, comfort, safety, and transportation of the human body－this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items. Among them are vacation trips, the best medical care, and entertainment.
One this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level probably would involve wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. In this way, we can enjoy more fully the good things on the first four levels.
A. Then a third level appeared.
B. Human wants seem endless.
C. When there is money enough to satisfy one level of wants, another level appears.
D. There are several levels of wants in one’s life.
E. At this stage, we now may seek to ensure the health, safety, and leisure.
F. Also included here are fancy foods and the latest styles in clothing.
G. Different people have different wants on each level.

查看习题详情和答案>>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.
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.

同位语从句与定语从句的区分
1)The proposal that he put forward is to be discussed at the meeting．
2)The proposal that we should hold sports meeting is to be discussed．
a．句1)是________从句，that在从句中________成分，句2)是________从句，that在从句中________成分，而且一般不省掉。
b．定语从句用来说明先行词的性质特征，起修饰或限制作用；同位语从句用来解释说明句词的内容，二者是________关系。
c．区分时可以在先行词与从句之间加一个系动词be，使之构成一个新句子，如果句子通顺且符合逻辑，则为同位语从句，反之，则为定语从句。
例如：The report that he was going to resign was false．他将辞职的传闻是假的。因为the report was that he was going to resign句意通顺，所以，that he was going to resign是同位语从句。
