4."No field of study can advance significantly unless outsiders bring their knowledge and experience to that field of study."

(范文)

Nowadays quite a lot colleges and universities have designed some humanistic curriculum providing as something compulsory to the scientific major students while to the literary major also a modest quantity of scientific courses have been given in order to balance the proportion of both knowledge ken. It certainly symbols a sign that different academic disciplines are gradually coming to across and the billow of the information currents is now blushing the explicit boundaries separating the major confluence, making them more and more ambiguous and impel them into the position of interrelated in that the knowledge of one field can sometimes shed beams of twilight on the studies of other fields.

As what is now more popular and acceptable by many successful entrepreneurs, the fresh idea of borrowing the dealing methods from mathematics to compensate the drawbacks of the traditional evaluation approaches used in the field of economy is displaying a unique glamorous charisma. For instance, ancient merchants nearly always had the headache to cope with the data treatment, which can help them to make clearly the trend of the offer-need relationship instructing them to adjust the weight of this relationship into approximately balanced avoiding the loss of the largely instilled investment. Obviously primitive arithmetical approaches like simple counting, enumerating, or assorted fundamental calculation including the plus, minus, multiply and divide must be far not enough, they were eager to conduce to a new convenient weapon specially trenchant to tamp this gap, so the quantitative methods accordingly born to dislodge the stranded commercial ship owing to generations of endless trials. Today's shrewd businessmen can easily deal with these problems just constitute a data repository in their own computers installed with the powerful exploited quantitative procedure software, no sooner do they enter the fluctuated data into the storehouse than a mobile accurate diagram immediately folded out in front of your sight, transforming with the change pace of the economy heart, surely the glamour of the collaboration of the two fields is.

If literary critics intend to put up a bulletin filled with some abstruse theory with their own unique clairvoyance, the principles of philosophy accumulated through several centuries are the best things they should consider to resort to further their study domain. As a famous American literary critic ever wrote in his latest book“Literature against Philosophy”, that both the subjects here concerned acts the roles of the brothers share in some common like the features of genes and attitudes towards outer evaluations, yet fight each other for the predominance of his own thinking rules in that the existence of the common and concordance mentioned above. Many literary works inevitable dips into the field of philosophy in the form of further exploring the deep ground of the hero or heroine's heart by depicting the countenance or the behavior deriving from his or her natural revelation, one of the eminent examples is the Mary Shelley's appealing fiction "Frankenstein", the adept almost near the surface of perfect description and metaphorical expression fixed thousands of reader's eyes and souls onto the monster's fate and the hero's imminent manic psyche, the philosophical analysis told us how it produces so hallucinating effect and weird atmosphere.

By the way, when biology and chemistry met, biochemistry came into being as a strong hybrid of the two independent parents. One of my best friends happens to be an excellent graduates major in bio-pharmacology, who once told me before entering the total systematic study of this newborn popular course, he must prepare the rationales of chemistry indispensable and necessary in later research assignments. After the collection of the blood samples, we should certainly not directly put them under the micro-instruments to observe and then make out the papers about analysis of the results, as a prerequisite our researchers have to import some chemical reagents as an additive instilling into the specimens to function with the blood ingredients, only after the process can we take them into analysis. Without the chemistry, biology is just a pond of backwater and vice versa, any bio-chemical scholar ought to taste the exceptional favor.

So much have been discussed in details covering three particular domains, in a sense, illustrates the interrelationship is the guarantee of the breakthrough of some certain academic topics, possibly in some special circumstances can also be generalized to a more broaden range. No field after all, I believe, can survive well surrounded by the asphyxiating academic buttress; the only escape is breaking it from outside. (744 words)

161."In this age of intensive media coverage, it is no longer possible for a society to regard any woman or man as a hero. The reputation of anyone who is subjected to media scrutiny will eventually be diminished."

(范文)

Hero, the elites of our human groups, are all time alive in any level of social stages. But, following the break-neck development of various fields of technology, a serial of problems accordingly come to bog us, one of them is the exclamation of the phenomenon-dilution of the concept "hero". As what is asserted at top line, heroes are not vacant at any time, so what's the root of this dramatic fact? Media, the media; just as a result of this modern product exorcises the long inherited convention of hero idolization.

In our childhood, what we most like to hear about is the splendid experiences of our famous predecessors, like George Washington, the primary president of United States, who also contributes large amount out of assessment to the final independence of the nation. Almost hardly to remember how many times having acclaimed for this or that miracle in his war life, and the ambition illuminated from his encouraging stories, we still, however, remain the tepid admiration even until today. While, let us have a look at today's conditions, heroes have been drawn by huge piles of information garbage, and the real ones deserved our fervid accolade even finally loses his favor by the collision of fashionable value-evaluate trend, such as the currents of idolization towards those film stars.

No deniably, the unique price of hero is now decrying, which never can be evaluated at the same scale as ever before, owing to the overwhelming power to concoct crowds of meretricious "heroes" by media. Information, the fundamental source of people have to every day rely on, is the major products like other commodities of the media corporation; then as a result, the quality and reality extent is wholly mastered under the control of the media propaganda, so long as the publication is strong enough, even sun can someday legitimately rise from the west horizon. How can citizens tolerate such rules of operation to be compliant to these absurd tricks and consequently become their allegiant followers?

And taking the instance of those who really could be responsible for the entitled appellation of "hero", due to the overexposure of nearly each dimension of their lives (such as privacy, ordinary schedule, the sum of his property, so on and so forth), no singularity can he or she gives to us to enable us to respect them at all. Most of our primordial respects stems from the presumption of their particularity or characteristics, which always occluded to public as an abstruse mystery, but once the born of media and the authorization for it to freely reveal every corner of everything, the mysterious ages are destined to not drive back again. Just like awakening from a sweet dream, people will find the hero idolized so many years is merely a person too ordinary to be absolutely discriminated from we these similarly ordinary ones. And with the disappearance of these veiled dreams, "hero" eternally eludes into the history of past.

From the principles of natural laws, not a single type of species can be originated as personal will, nor with the extinction of certain phylum, while the media is trying their best to challenge against these "gold laws" to evince his revolutionary magic. Nevertheless, real hero will never miss his merited title of hero if he equips the quality, I always believe, no matter what is he under the embellishment of the magical media and how lonely he might taste.

235."Most people are taught that loyalty is a virtue. But loyalty whether to one's friends, to one's school or place of employment, or to any institution is all too often a destructive rather than a positive force."

(范文)

Once I participated a speech given by a famous local entrepreneur, who rose from exactly bare hands. The word brands me most is "loyalty", the very one we hardly dabble and almost reaches the edge of oblivion but instead no negligence is deserve. How can this concept bridge the relation with the huge lope of his life? Loyalty makes one stick to a goal without any fickleness until achievement, which has won a lot much for him including friendship, dependability and love. Ironically, today's people is becoming more and more "sagacious" to plan for themselves better, holding the principles of choosing best, moving fastest, and snatching most; in other words, loyalty is degenerated into a totem of stubborn stereotype inadaptable for the society of profits first.

Is that modern theory "true"? And what about the success of that admiring entrepreneur? Something people primarily should understand is the indispensability of credence active among human community for the perpetuity of humanistic relationship, which to a large extent stems from this loyalty. No exaggeration I have made to emphasize its paramount function to personal survival, either from the fable or history we can learn the lesson. But now I would like to continue to elicit the example of that manager upstairs. When he is still an employee working for this consult company (before he climbed up to the top rung of the company committee), there was a huge recession leading to a total profits declination in this operating domain, in the end results almost all elites of the company to make a job exchange except him. His persistent determination was for nothing but loyalty, of his indebtedness form his boss, of his enamored undertaking tolerating for no intermittence, of his adherence to goal successful for sure. And fact tells us everything, as each audience can see, he did.

Not only to individual the quality of loyalty can push one into the acme of his career following with winsome reputation, but also to community the crucial pillar to support the sculpture of serenity goddess. Once separated from the loyalty, credence also accordingly right away being crushed under the wheels of history cart, and then the concomitant condition can be imagined as this: various associations would be certainly collapsed under the circumstance deprived of dependability, each one discredits the motive of action from anyone else, talking is evolved into a serial of satirical assaults, compassion sounds more like a snicker, and ultimately ineluctably the human society is degraded into a state of depravity. Is this the community we each of us want to live in? Is this the situation we each of us want to make realized? If your answer is negative-just like mine-then please retrospect your conscience to retrieve this precious virtue of "loyalty".

While the merits of loyalty have been corroborated here so strongly, admittedly, however, loyalty applied only to the legitimate partner or purpose, not involves the malign ones, somehow or other the effect will surely arrive at the surprising reverse. For instance, from the point of penal law, excluding the major miscreants who abet the underlings to commit guilt, the adherent to follow his felony, even if he never directly join in the crime doing on the spot, but as a result of his ancillary work, he should also assume a certain quantity of the great responsibility, which might mean him a ferocity of being disenfranchised, or at the same time to enjoy his later few years' prime time in the jail. The tragedy is so natural for most of us that admonishing clock is being struck; the high time for us to wake up from the sequacious loyalty is coming.

Overall, the virtue of loyalty is one of the fundamental factor heading for our prosperous tomorrow, despite its contain of some potential stygian side effect turning to the malicious dimension, yet no doubt it deserves to be advocated to learn for the brace of the beneficial development of both single person and gross society. Like the rationale of any medicine we take normally, no one of us will stop to ingest pills of penicillin just because its possible allergy to some particular patients, after all its application and efficacy is indelible.
