According Halliday and Hasan,cohesion can be achieved through two ways. One is lexical cohesion and the other is grammatical cohesion. Reference is one of the most important devices in grammatical cohesion. It can be divided into personal reference,demonstrative reference,and comparative reference. Some of these references can be used as cataphora,some can be used as anaphora and some can be used as both. Analysis and explanation as well as examples are provided in this paper to facilitate the reader's understanding and use of reference.展开更多

For one smaller problem, there may be more than one software design but who will be the best;depends on the complexity level of software design. Therefore, coupling and cohesion which shows the interlinking of classes and strength of classes;control the complexity of the design. The best software object oriented design is based upon the low coupling and high cohesion level. In the present work, a real case study of Life Insurance policy for handicapped person is demonstrated through the UML Class Diagram;coupling and cohesion levels are measured and results are demonstrated in the form of tables.展开更多

And for the college graduates, reading is the main way through which they obtain information needed in their specialty.Most often, students think their problem in reading is vocabulary, which is not necessarily true. Sometimes even the readers look up all the new words, it is still hard for them to understand the text exactly and thoroughly. Though vocabulary plays an important role in reading comprehension, it may not be the biggest hindrance on our way of correct comprehending. English reading teaching shouldn't be confined to the teaching of vocabulary or sentences but should develop students' ability to analyze text beyond sentence level. It's impossible to cover all the aspects of discourse analysis in one article and since cohesion is important and basic knowledge of discourse analysis, we will concentrate on the cohesive functions of discourse in English reading in this article.展开更多

文摘Discourse analysis is gaining its prominence in teaching reading. The paper presents an example of analyzing the system of reference and lexical cohesion of a news report. It demonstrates how to involve discourse analysis into the teaching of newspaper reading in order to make students get a clear framework of reference and lexical cohesion in a functional-grammar-conscious manner.
文摘In the study of textlinguistics,cohesion is one important subject. According Halliday and Hasan,cohesion can be achieved through two ways. One is lexical cohesion and the other is grammatical cohesion. Reference is one of the most important devices in grammatical cohesion. It can be divided into personal reference,demonstrative reference,and comparative reference. Some of these references can be used as cataphora,some can be used as anaphora and some can be used as both. Analysis and explanation as well as examples are provided in this paper to facilitate the reader's understanding and use of reference.
