Grammar Experimental Practice:Inductive Approach in Teaching ’Passive Voice’

Teachers are always in search of better ways to suit a variety of language needs and learning skills.The inductive approach allows the learners to examine samples of language first and discover the rules by themselves.That is to say,the learners generalize the rules from the particular.As a new approach in teaching grammar,the process of the inductive activities challenges and motivates many learners.The purpose of this essay is to examine the inductive approach applied in a microteaching grammar class and to evaluate the advantages and disadvantages of the procedure,and then to identify the ways in which it may be successfully adopted in future teaching proactive.     

Analysis of Second-Order Effect in Frame

The second-order effect is the interaction between the vertical load and the deformation in a vertically forced element. In order to deduce a more brief but practical method, which has considered the second-order effect in a sway frame, some factors which affect the second-order deformation in a sway frame should be generalized based on a more accurate method. Nonlinear finite element is adopted in this paper, and according to this theory, a program, which can calculate the inner force and the deformation of the sway frame considering the second-order effects is coded.     

Elementary Introduction To The Differences Of Chinese And Western Cultures And Cross-cultural Communication

Introductory: At present all kinds of teaching methods are widely used in or out of the country.The important one is functional teaching method.It originated in 1970's and was in vogue in 1980's.The main reason is that in order to suit the needs of rapid economic development,the members of European Community try to organize more than 100 linguists and specialists of teaching methods to study and explore and find out a kind of functional teaching method,which is what we know that the language is regarded as a kind of communicative tool among human beings. From that time ,almost all the countries have adopted and arranged teaching ways and teaching contents in a practical purpose.     

Perturbation spectrum method for seismic analysis of non-classically damped systems

Fundamental principles from structural dynamics, random theory and perturbation methods are adopted to develop a new response spectrum combination rule for the seismic analysis of non-classically damped systems, such as structure-damper systems. The approach, which is named the perturbation spectrum method, can provide a more accurate evaluation of a non-classically damped system＇s mean peak response in terms of the ground response spectrum. To account for the effect of non-classical damping, all elements are included in the proposed method for seismic analysis of structure, which is usually approximated by ignoring the off-diagonal elements of the modal damping matrix. Moreover, as has been adopted in the traditional Complete Quadratic Combination （CQC） method, the white noise model is also used to simplify the expressions of perturbation correlation coefficients. Finally, numerical work is performed to examine the accuracy of the proposed method by comparing the approximate results with exact ones and to demonstrate the importance of the neglected off-diagonal elements of the modal damping matrix. In the examined cases, the proposed method shows good agreement with direct time-history integration. Also, the perturbation spectrum method leads to a more efficient and economical calculation by avoiding the integral and complex operation.     

Initiating Interaction in the EFL Class

In recent years,with the renewal of English textbooks of all levels,the traditional grammar-translation method is out-of-date in the EFL class.In order to meet the challenges of our age,more and more teachers have cast their eyes on the communicative use of language,which compels them to create opportunities for genuine interaction in the classroom.Interaction,according to Brown(1980,p.159),is "the collaborative exchange of thoughts,feelings,or ideas between two or more people resulting in a reciprocal effect on each other." As the core of communication,interaction is a very important word for current language teachers,who are responsible for providing the stimuli for continued interaction in the era of communicative language teaching.The significance of interaction in EFL class mainly lies in its contribution to the active teaching of grammar,the initiating of students’ intrinsic motivation and the improving of their communicative competence(c.c.).In this article,I will elaborate on why and how I initiate interaction by providing a 100-minute lesson plan in an attempt to connect theory with practice.     

Group Work in Spoken English Teaching in Vocational School

In English class,teachers are inclined to instruct linguistic knowledge,neglecting the training of students’ linguistic behavior.Especially under the whole-class teaching mode,the opportunities for students to practice spoken English are rather limited in the class.Based on the theory of Cooperative Learning,group work,which is a kind of teaching method,will effectively solve this problem.My research is to study the influence of this activity on the students’ English learning through questionnaire in vocational college and how to make this activity more effective.     

弱可串行分布式实时事务并发控制

Most of the proposed concurrency control protocols for real-time database systems are based on serializability theorem.Owing to the unique characteristics of real-time database applications and the importance of satisfying the timing constraints of transactions,serializability is too strong as a correctness criterion and not suitable for real-time databases in most cases.On the other hand,relaxed serializability including epsilon-serializability and similarity-serializability can allow more real-time transactions to satisfy their timing constraints,but database consistency may be sacrificed to some extent.We thus propose the use of weak serializability(WSR)that is more relaxed than conflicting serializability while database consistency is maintained.In this paper,we first formally define the new notion of correctness called weak serializability.After the necessary and sufficient conditions for weak serializability are shown,corresponding concurrency control protocol WDHP(weak serializable distributed high prority protocol)is outlined for distributed real time databases,where a new lock mode called mask lock mode is proposed for simplifying the condition of global consistency.Finally,through a series of simulation studies,it is shown that using the new concurrency control protocol the performance of distributed realtime databases can be greatly improved.     

Linkage intensity learning approach with genetic algorithm for causality diagram

The causality diagram theory, which adopts graphical expression of knowledge and direct intensity of causality, overcomes some shortages in belief network and has evolved into a mixed causality diagram methodology for discrete and continuous variable. But to give linkage intensity of causality diagram is difficult, particularly in many working conditions in which sampling data are limited or noisy. The classic learning algorithm is hard to be adopted. We used genetic algorithm to learn linkage intensity from limited data. The simulation results demonstrate that this algorithm is more suitable than the classic algorithm in the condition of sample shortage such as space shuttle’s fault diagnoisis.     

Third-Party Mediation in International Relations:Principles and Key to Success

In today’s complex and more interdependent world,countries struggle to maintain the balance between their national interests and stable international relations.Therefore,third-party mediation becomes a popular method in resolving on-going or even historical conflicts between nations.How the mediation process is being adopted is quite important,and there are number of elements that determine the achievement of mediation in the conflict resolution,such as role of mediator,mediation impartiality,and the techniques of mediation.Eventually,third-party mediation help to facilitate the contradiction yet cannot remove the ultimate discord among nations,in which it will take a long way to go in the international political arena.     

The Inspiration of The Interpreter’s Roles to College English Teaching

Jef Verschueren is the representative of European Continental pragmatic thought.He puts forward a new theory that pragmatics is a perspective on language and he uses the theory of adaptation to analyze pragmatics."The general concern for the study of linguistic pragmatics is to understand the meaningful functioning of a language as a dynamic process operating on context-structure relationships at various levels of salience"(Verschuren 2000:69).The focal points in contexts are the utterer and the interpreter,for the physical,social and mental aspects of contexts are activated by language users’cognitive processes.Verschueren divided interpreter’s roles into five types:addressee,side participant,bystander,listener-in and eavesdropper,which can explain the adaptation of context and language choices.This is also applicable in college English classroom as the English class is also a context.At present students taught at the same time by the same teacher do not master the knowledge at the same level.One of the reason is that students are not engaged in the class at the same level.According to the Verschueren’s theory,the best English teaching class is one that each student in the addressee of teachers.Addressee is a metaphor which means everyone should follow the teachers’explanation carefully and take part in the teaching activities.It has something to do with interaction theory,which considers students as active individuals but not passive receivers.One of the common interaction patterns is questioning.In this thesis,the question how to make students addresses through adoption of questioning approach in college English class will be researched.

Gardeners and Cinema Tickets: High School Students' Preconceptions of Concurrency

We are developing a course in concurrency for high school students. The course is being developed in phases of refinement on the basis of feedback received from teachers and students. We have found persistent difficulties that students have in understanding fundamental concepts, which has led us to investigate their preconceptions of concurrency. This paper describes the results of this investigation. The work is anchored in constructivism, which stresses the importance of prior knowledge upon which new knowledge is built. The students were asked to solve concurrency problems, both prior to the course and after learning just the basics of the subject. Analysis of solutions reveals that students: (a) find that solving a problem on the order of actions is more natural than the critical section problem, (b) are divided in their preference for centralized and decentralized solutions, (c) employ inappropriate heuristics, (d) invent computational models as they work, (e) attribute parallelism where it does not exist, (f) attribute intelligence to systems. Based on these findings, we were able to modify the course to address these problems of prior knowledge.     

Similarity based mixed transaction concurrency control protocol

1 Introduction 1 Real-Time database applications, such as stock trading systems, telecommunication managements, and air traffic management are characterized by large volume of data as well as time constrained data access [1]. The correctness of such applications depends on both execution results and time constraints imposed on transaction commitments, generally in terms of deadline. Based on the different consequences of deadline missing, transactions in a real-time database systems (RTDBS) …
