Abstract: This research uses iThink software of system dynamics as the research tool, and establishes a causal feedback diagram of a kindergarten operation. The feasibility of this model was tested finally. When influence some factors of the profit to change fast, it can offer and change profits predict immediately. In this way, the operator find about method to improve management then avoid risks faced ahead of time.

Abstract: In this paper, we propose an automatic preposition correction method for Chinese learners of English. Our corpus comes from Chinese learners of English Corpus (CLEC). We use N-gram model to extract the semantic features based on the form of the word in context, part of speech tagging and syntactic parse tree. Meanwhile, this paper proposes a new method based on mutual information and improves the training and classification method. This method’s performance has been improved in terms of both effectiveness and efficiency, and the results show a significant improvement compared with the previous results.

Abstract: The study sought to compare the occurrence frequency of academic vocabulary in abstracts written by experts and Chinese undergraduates by investigating 60 RA abstracts in applied linguistics. The results show that the coverage of AWL is similar in the abstracts written by these two groups of writers, however, different preferences of academic vocabulary are detected in their abstracts. The findings have significant pedagogical implications for novice writers’ abstracts wording in applied linguistics.

Abstract: With rapid tempo of development in the information technology, design model of information network based on three-layer structure and WCF could solve problems about dormitory managing work which relies on its merit as to independence of programming language and platform. It makes programmers’ distribution and collaboration of tasks more effective to apply key technology of three-layer structure and Web Service to student dormitory management system’s design and implement. Therefore, developers of system can pay more attention to the relative business logic in order to reduce difficulty of maintenance in late stage of software development life cycle. Moreover, it does not need artificial intervention to realize RFID which has speedily and convenience operation. In this case, efficiency of managing work and unity of system data can be guaranteed.

Abstract: Distributed computing and Resource sharing in large-scale heterogeneous system are the key to realize mobile learning system. This paper sets up a mobile learning service system through the construction of teaching cloud platform and cloud resources, cloud resource sharing, application and service of cloud resource, system and mechanism construction. The mobile learning network system is established by building models of it, which realizes mobile learning, collaborative learning and the situated learning anytime anywhere with freedom, individuality and diversification.
