现代汉语"吗"问句的信息结构与功能类型   总被引:1,自引:0,他引:1  
文章以“吗”问句为研究对象,探讨了以下几个问题:1.根据“吗”字的历时演变过程析离出了现代汉语“吗”问句的三种功能类型:询问求知句、猜度求证句和反诘质疑句;2.运用传息语法的有关理论分别考察了影响“吗”问句功能类型的几种信息结构;3.运用信息结构的分析方法对某些同形异义的“吗”问句进行了析离;4.在余论中,还提到了其他影响“吗”问句功能类型的因素。通过以上的分析.文章试图说明信息结构是制约人们理解问句功能类型的主要因素之一。  相似文献

There is an increase use of wireless technologies in education all over the world. In fact, wireless technologies such as laptop computers, palmtop computers and mobile phones are revolutionising education and transforming the traditional classroom-based learning and teaching into anytime and anywhere education. This paper investigates the use of wireless technologies in education with particular reference to the potential of learning new technical English language words using Short Message Service (SMS) text messaging. The system, developed by the authors, called mobile learning tool (MOLT), has been tested with 45 1st-year undergraduate students. The knowledge of students before and after the experiment has been measured. Our results show that students enjoyed and learned new words with the help of their mobile phones. We believe that using the MOLT system as an educational tool will contribute to the success of students.  相似文献

The present study investigated the utility of an instructional strategy known as the query method for enhancing learning outcomes in computer-based training. The query method involves an embedded guided, sentence generation task requiring elaboration of key concepts in the training material that encourages learners to ‘stop and think’ about the information already presented before proceeding to new concepts. This study also investigated the effect of varying the level of elaboration (low or high) prompted by the queries. Fifty-one undergraduate students from the general psychology department subject pool at a major university in the southeastern United States received instruction on the basic principles of flight via one of three versions of a computer-based tutorial (no query, low-level elaboration query, or high-level elaboration query). Participants had no prior knowledge or previous experience with the aviation domain. A one-way between-groups design was employed, with the query method serving as the independent variable and a sample size of 17 per condition. Dependent variables included knowledge organization, knowledge acquisition, and instructional efficiency. Overall, results showed that incorporating low-level elaboration queries into the training resulted in improved organization, integration, and application of task-relevant knowledge and higher instructional efficiency. High-level elaboration queries consistently failed to produce significantly better post-training outcomes, possibly due to the increased cognitive load imposed on learners during training. The discussion centers on theoretical and practical implications for promoting and assessing learning outcomes in computer-based training.  相似文献

短信并不能笼统地被称为文学,冠之以“短信文学”。短信文学是一个集合概念,是指具有文学性的那部分短信,短信文学是指文学性短信,指篇幅短小、富于意味、用于手机交流的短信;短信文学也是一个文体术语,它是一种篇幅短小、富于意味、用于手机交流的文本样式。以“短信文学”而不以“文学性短信(或文学短信)”名短信中具有文学性的那部分,是因为它具有区别文体的意义。  相似文献

This paper explores the application of term dependency in information retrieval (IR) and proposes a novel dependency retrieval model. This retrieval model suggests an extension to the existing language modeling (LM) approach to IR by introducing dependency models for both query and document. Relevance between document and query is then evaluated by reference to the Kullback-Leibler divergence between their dependency models. This paper introduces a novel hybrid dependency structure, which allows integration of various forms of dependency within a single framework. A pseudo relevance feedback based method is also introduced for constructing query dependency model. The basic idea is to use query-relevant top-ranking sentences extracted from the top documents at retrieval time as the augmented representation of query, from which the relationships between query terms are identified. A Markov Random Field (MRF) based approach is presented to ensure the relevance of the extracted sentences, which utilizes the association features between query terms within a sentence to evaluate the relevance of each sentence. This dependency retrieval model was compared with other traditional retrieval models. Experiments indicated that it produces significant improvements in retrieval effectiveness.  相似文献
