The job of teaching is one of the most important careers that exist in this modern day in which we live. It is much more than a job. It is a vocation with it the connotation of a call upon an individual's life to sacrifice all that he has, and is in order to shape the lives of those who have been entrusted to his care. The teacher, though highly regarded and respected, is still one of the lowest paid professionals anywhere in the world. This is sad, but true. An individual seeking to amass a  相似文献

The exact solution for the combined KS and KdV equation is obtained via introducing a simple and effective nonlinear transformations.This method is very concise and primary and can be applied to other unintegrable nonlinear evolution equations. It is common knowledge that the Korteweg de Vries(KdV) equation [1] (1) has been proposed as model equation for the weakly nonlinear long waves which occur in many different physical systems; the Kuramoto-Sivashinsky (KS) equation is one of the simplest nonliaear partial differential equations that exhibit Chaotic behavior frequently encounted in the study of continous media [2-4] . Many interesting mathematical and physical properties of eqs. (1) and (2) have been studied widely. But, in several problems where a lonq wavelength oscilatory instability is found, the noulineai evolution of the perturbations near rriticality is governed by the dispersion modified Kuramoto-Sivashi nsky equation(3)ft is clear that this equation is a combination of the KdV and KS  相似文献

1. IntroductionHumans have the ability (or competence) to think logically, and this is an undeniable fact. However,what this ability consists in is a difficult question. It might be said that logical ability consists in theknowledge of a set of logic rules. But what are those logic rules? For centuries logicians have devel-  相似文献

This paper outlines the main context of relevance theory,an inferential approach to pragmatics,which is based on a defi- nition of relevance and two principles of relevance:a Cognitive Principle(that human cognition is geared to the maxi- mization of relevance),and a Communicative Principle(that utterances create expectations of optimal relevance).Defi- nition of relevance and the motivation for these principles will be explained,and criticisms of them will be presented re- spectively in this paper.  相似文献

Historically, women have becn considered to be inferior to men. They have discriminated in one way or another. This unequal sexist phenomenon is reflected in language, too. Rccently, thcre has becn a noticeablc increase in the numberof articles and books on the subject of Language and Sexism. We have noticed sexism exists in language and women have a language of their own, which is different from and inferior to the language of men in socicty, This paper attempts to discuss such kind of inequality in English language.  相似文献

By using semi—micro—iodometrie method.the comparative studies on thb absorbent power of differant ions by different soil samples have been developed.It is noteworthy that the proposed technique is rapid and more reproucible.The theoretical equations are derived and the exoerimantal proceuresdare described.The maenitude of absorbent power of ion by soils is the intensity factorrespect to that of capacity factor.The reciprocal of coefficent of soil absoreent power of ion has been assumed to reprcsent the magnitude of soil absorbent power when the soil having been taken as reference has been fixedAccording fo this method.results of the absorbent power of different nutritious ions for cerfain paddy soils are presented.we get a linear relationshibatween ion—exchange adsorption of soil and nutritious ions.Tha absorbent power is not only a basic feature of soil except it's chepical and physical property but also a fandamental character for ions.Fathermore,in the practice.the absorbent power of nutritious ionsasNH_4~+,K~+,Ca~(++)and Mg~(++)has been invstigated,The absbent cower of ions bycoarse sandy earth and clayloam,the relationship befween absorbent powemand cultural practice as well as a significant illnstration ete are also discusd in details.All these results have clearly displayed the significance of soil absorbent power in the respect of directing the plant nutrition and the adequatefertilization.  相似文献

Prehistoric archaeology has progressed a large step since 1949 and manyquestions were solved after a great number of prehistoric sites had beendiscovered.It is generally accepted that in the neolithic age of China thereexisted two types of culture:the 1st is the well-known“Painted-pottery Culture”in the north-web,tern part,the 2nd is the“Black-pottery Culture”in the easternpart of China;while the 3rd one the“Printed Geometric-designed potteryCulture proposed by other scholars and the writer(In my former papersbeginning from“A Neolithic site in Wuping Fukien”read in the 3rd Congressof Far-eastern Prehistorians held in Singapore Jan.1938)as that of the south-eastern region of China has not yet been determined until now.The recentdiscoveries in this region including that of Hot'ien as dealt with in this paper,however,have provided many valuable evidences to this hypothesis.  相似文献

As the oldest and most frequently used conventional expressions,Chinese proverbs usually represent the way of thinking of the Chinese people.Metaphors,one typical type of Chinese proverbs,try to establish a relation of equality between two relatively dissimilar entities, such as time and money.The ability to understand and to use figurative language is related to one's social competence and professional achievement.In order to reveal the mechanism of proverb processing,the current study takes a close look at the nature of semantic properties and their inter-relationships in Chinese proverbs.522 Chinese sentential proverbs(the two clauses of the proverb are of the same syntax,e.g.,“人活脸,树活皮”)were presented to 360 university students.They were asked to rate the familiarity(1 for least familiar, 7 for most familiar), predictability(1 for least predictable, 7 for most predictable),agreement(1 for least matched between the two clauses,7 for most matched between the two clauses),degree of being understandable(1 for least understandable,7 for most understandable),and imaginability(1 for least imaginable,7 for most imaginable)based on a 7-point Likert Scale,as well as age of acquisition(AOA).Correlation and regression analysis were conducted based on these ratings. The results show a significant positive correlation between familiarity and each of the rest semantic properties,which are consistent with the findings of the previous work.A significant negative correlation between age of acquisition and each of the rest semantic properties is also observed in the current study.However,no significant correlation is found between familiarity and degree of being understandable,which might be due to the low rating of familiarity and the wide dispersity.In order to further reveal the inter-relationships of semantic properties, hierarchical regression analyses are carried out and show that familiarity,imaginabiltity,agreement,and age of acquisition significantly predict the degree of being understandable,while familiarity and age of acquisition significantly predict the predictability of proverbs. Our results demonstrate that familiarity and age of acquisition are two important factors which influence our understanding of Chinese proverbs. In addition, the semantic consistency between two clauses of a Chinese sentential proverb and degree of imagination also play an important role in understanding idiomatic strings.Imaginability is related to the theory of″Dual Coding,″which argues that visual and verbal information are processed differently and along distinct channels in the human mind, creating separate representations for information processed in each channel.The mental codes corresponding to these representations are used to organize incoming information that can be acted upon,stored,and retrieved for subsequent use.Both visual and verbal codes can be used when recalling information.The ability to code a stimulus in two different ways increases the chance of remembering that item compared to if the stimulus is only coded one way.Our results suggest that the processing of a Chinese proverb partially relies on the accessibility to visual code of a proverb which is primarily affected by culture. Therefore, Chinese culture could influence the understanding of Chinese proverbs. Specifically,in the creating process,a number of concrete concepts are used to express the abstract inter-relationships through their similarity,e.g.,the relationship between a person(人)and his/her reputation(脸)is similar to that between a tree(树)and its bark(皮).In other words,the reputation of a person is as important as the bark of a tree.In order to successfully understand the Chinese proverbs,it is important to learn about the deeper meanings of″face″and″reputation″in Chinese culture.That explains why the comprehension of a proverb is significantly associated with one's culture understanding.Based on the current study,more studies should be conducted with a focus on the understanding process of proverbs,which will help reveal the mental mechanism of Chinese and preserving Chinese culture.  相似文献

Introduction English Language teaching as a profession has enjoyed a long history.And ever since itsinitiation,people have investigated different models in language acquisition/learning andteaching,although only in recent years has attention been paid to the studies of SLA.In theChinese setting,research in foreign language teaching(TEFL)has been made in the fashionof the theories of first language acguisition or SLA,for it is believed that the contributions tostudies of the input provided by mothers(i.e motherese) in L1 acquisition and teachers inter-locuters in SLA are necessarily important for understanding the direction that TEEL researchhas followed,as they have provided both a methodololgy for investigating input and the re-search questions.The behaviorist,the cognitivist and the interactionist approaches have putforward different models in interpreting L1 acquisition and SLA,which obviously have theirown merits and demerits,depending on the level at which they are employed and the purposethey are  相似文献

Of these, many are best seen as extensions of classical logic, including both thoseof interest to mathematics and those of interest to philosophy and computer science.

Although language study can be very interesting, it is admittedly about the most complex type of learning that a student can undertake, it is very important that we realize that language study is different from the study of science or mathematics and is more complex. Therefore the mechanical methods employed in the learning of multiplication tables, for example, may not be he most appropriate methods to use in teaching language. Real ability with language is the ability to communicate ideas. A student may know a lot of sentence patterns and rules of grammar and  相似文献

We had guests last night who have not stayed in a B&B hotel ago. They did not want breakfast because that they were going out early in the morning. They came back lately and had some tea. I came into the riving room and saw one of them just go through the kitchen door but turn on the light. He was looking for a glass the cupboard. He had no ideas that the kitchen was not for guests. I just smiled to me and thought, “What can I do? We are guests after all.”  相似文献
