It is an important way to communicate with others; also it is the foundation of mastering a foreign language. However, the higher vocational students usually lack the background information about the listening materials and seldom know how to make inferences according to the specific contexts. The author conducted an empirical study lasting one semester in Higher Vocational College of Dahongying University trying to apply Relevance Theory to listening comprehension and guide listening comprehension learning within the framework of Relevance Theory to finally improve higher vocational students＇ ability of listening comprehension.展开更多

However, the reading effect seems unsatisfying,which poses a great challenge for reading teaching. In this paper, the author explores the reading process andapplies the Schema Theory, in order to prove the important role of background knowledge in readingcomprehension. Based on this discussion, suggested teaching methods are available for employing backgroundknowledge in reading teaching.展开更多

The system has extensive physical background. The exact solutions of the Boiti-Leon-Pempinelli system are investigated using similarity transformation method via Lie group theory. Lie symmetry generators are used for constructing similarity variables for the given system of partial differential equations, which lead to the new system of partial differentiaJ equations with one variable less at each step and eventually to a system of ordinary differential equations （ODEs）. Finally, these ODEs are solved exactly. The exact solutions are obtained under some parametric restrictions. The elastic behavior of the soliton solutions is shown graphically by taking some appropriate choices of the arbitrary functions involved in the solutions.展开更多
