As an American is always striving to change his lot, he never fully identifies with any group.
In America, there are no such expressions such as in china where “the fat pig gets slaughtered,” or in Japan, where “the nail that sticks out gets hammered down.”
This freedom from the group has enabled the American to become “Economic Man”-one directed almost purely by profit motive, mobile and unencumbered（不受阻礙的）by family or community obligations.

No one could seriously think that anyone who grows up poor, lives in a bad neighborhood, and attends an inferior school has an opportunity equal to that of someone more favored.
Americans may not have achieved equality, but at least they aspire to it, which is more than many other nations can claim.
In many countries, when jobs become available for young people in distant cities, when television begins to dominate home life, when ready - made foods appear in the markets, the culture appears more “American” - although the resemblance could be entirely superficial.
Someone who looks around or down appears shifty （不可靠的）to Americans, although in fact one doesn’t stare continuously at the other person, but glances elsewhere every few seconds.

As the case illustrates, competition takes four general forms: pure competition, monopoly, monopolistic competition, and oligopoly（少數(shù)制造商對市場的控制）.
The classic example of pure competition occurs with a commodity, like wheat or corn, that has so many producers that no one of them can control its selling price.
A monopoly occurs when one company alone offers a particular food or service and therefore controls the market and price for it.

Moreover, both common sense and our experiences with children inform us that people tend to mimic the language and behavior they are exposed to.
Those who advocate unbridled individual expression might point out that the right of free speech is intrinsic to a democracy and necessary to its survival.
In sum, it is in our best interest as a society for the government to censor broadcast media for obscene and offensive language and behavior.

However, just the opposite may be true under certain circumstances.

邏輯問題分析論證句式

The mere fact that ticket sales in recent years for screenplay-based movies have exceeded those for book-based movies is insufficient evidence to conclude that writing screenplays now provides greater financial opportunity for writers.
It is possible that fees paid by movie studios for screenplays will decrease in the future relative to those for book rights.
The argument fails to rule out the possibility that a writer engage in both types of writing as well as other types.
In any event, the advertisement provides no justification for the mutually exclusive choice that it imposes on the writer.
The argument simply equates success with movie ticket sales, which is unwarranted.
The author assumes that physical capabilities are the only attributes necessary to operate a motor vehicle.
Moreover, the author provides no evidence that the realism of color photography is the reason for its predominance.
This assumption presents a false dilemma, since the two media are not necessarily mutually exclusive alternatives.
Common sense tells us that a photographer can succeed by working in both media.
The argument ignores the factors - such as initiative, creativity, technical skills, and business judgment - that may be more important than the choice of medium in determining success in photography.
The major problem with the argument is that the stated similarities between Company A and B are insufficient to support the conclusion that Company A will suffer a fate similar to Company B’s.
Consequently, the mere fact that Company A holds a large share of the video - game hardware and software market does not support the claim that Company A will also fail.
Thus, the author unfairly assumes that highly - rated public television programs are necessarily widely viewed, or popular.
While this may be true in some cases, it is equally possible that only companies with products that are already best - sellers can afford the higher ad rates that popular shows demand.
Admittedly, the vice president’s reasoning linking employee benefits with company profits seems reasonable on the surface.
One can infer from the survey’s results that a full one - third of the respondents may have viewed the current benefits package unfavorably.
Lacking more specific information about how these other employees responded, it is impossible to assess the reliability of the survey’s results or to make an informed recommendation.
It is unlikely that the brief one - week periods under comparison are representative of longer time periods.
If so, even though 3 percent more accidents occurred after the change, the author’s argument that changing the speed limit increases danger for drivers would be seriously weakened.
The editorial fails to take into account possible differences between East and West Cambria that are relevant to how drivers react to speed - limit changes.
In addition, while it is true that many voters change their minds several times before voting, and that some remain undecided until entering the voting booth, this is not true of everyone.
Without knowing the extent and nature of the damage resulting from the bad publicity or the reason for the violation, we cannot accept the author’s conclusion.
The author’s proposal is inconsistent with the author’s conclusion about the consequences of adopting an ethics code.
To begin with, the author fails to consider health threats posed by incinerating trash.
The author’s conclusion that switching to incineration would be more salutary for public health would be seriously undermined.
However, this is not necessarily the case.
The author’s implicit claim that incinerators are economically advantageous to landfills is poorly supported.
Consequently, unless the author can demonstrate that the city will incur expenses that are not covered by the increased revenues from these projects, the author’s concern about these issues is unfounded.
First of all, while asserting that real incomes are rising, the author provides no evidence to support this assertion.
But no evidence is provided to show that this explanation is correct.
Moreover, the author fails to consider and rule out other factors that might account for proportional decreases in spending on food.
The author ignores other likely benefits of agricultural technology that affect food pieces only indirectly or not at all.
In the first place, a great deal of empirical evidence shows that sequels are often not as profitable as the original movie.
However, unless the original cast and production team are involved in making the sequel, there is a good chance it will not be financially successful.
Since the difficulties inherent in this process make it hard to predict whether the result will be a success or a failure, the conclusion that the sequel will be profitable is presumptuous（武斷的）
This assumption overlooks other criteria for determining a bridge’s importance - such as the number of commuters using the bridge, the role of the bridge in local emergencies and disasters, and the impact that bridge closure would have on the economies of nearby cities.
Without such evidence, we cannot accept the author’s conclusion that no government funds should be directed toward maintaining the Styx River bridge.
The fact that the nearby city has a weakening economy does not prove that the city will not contribute significantly to tax revenues.
Substantiating this assumption requires examining the proper duty of government.
Accordingly, this assumption is simply an unproven claim.
The author is presenting a false dilemma by imposing an either - or choice between two courses of action that need not be mutually exclusive.
It is equally possible that legislators can address both areas of concern concurrently.
The argument relies on the assumption that the legislators in question（所討論的）have the opportunity to address urban crime problems.
Finally, the author unfairly trivializes the severity of rural crime by simply comparing it with urban crime.
It is possible that the sales trend in a particular location is not representative of sales in other regions.
However, the author fails to acknowledge and rule out other possible causes of such accidents.
A third problem with the argument is that the statistical evidence upon which it relies is too vague to be informative.
If the subjects for the study were randomly chosen and represent a diverse cross section of the population of shampoo users, the results will be reliable regardless of the number of participants.
Experience alone is far from being enough to guarantee minimized processing costs.
Given that Olympic Foods does benefit from lowered processing costs due to its years of experience, the prediction about maximum profits is still in lake of solid ground.
