Psychological linguistics provides a new point of view for college English teaching. From the aspect of psychological linguistics theory this paper discusses some issues, including how to train students to complete the reading process independently, how to build the schema to achieve integrated discourse comprehension, how to choose the most appropriate reading model, in order to improve the English reading skill and provide some enlightenment for college English reading teaching.展开更多

However, the elliptic systems involving the Hardy inequality and concave-convex nonlinearities have seldom been studied and we only find few results. Thus it is necessary for us to investigate the related singular systems deeply. In this paper, a quasilinear elliptic system is investigated, which involves multiple Hardy-type terms and concave-convex nonlinearities. To the best of our knowledge, such a problem has not been discussed. By using a variational method involving the Nehari manifold and some analytical techniques, we prove that there exist at least two positive solutions to the system.展开更多

The speech scripts and video excerpts from the subsequent manuscript collection with the CD-Rom published by FLTRP were studied. Lucas＇ framework of speech communication process was borrowed to bridge elements of the communication models and speech delivery process. Three key aspects of the speakers＇ encoding endeavors were under close examination： the verbal preferences, the non-verbal preferences, and the topic selection for exemplification. It was found that successful speakers demonstrated a clear and strong audience orientation. They chose more first person pronouns, fewer abstract words, a controlled number of dependent clauses, clear transition words, and limited figures of speech. They used very few verbal fillers, slips of tongue, a moderate speech rate and varied tone inflections. The speakers also showed distinctive features in gestures, eye contact and facial expressions. They employed anecdotes which shared a common field of experience. Pedagogical implications on the teaching of public speaking were discussed.展开更多
