摘要:
With the increasing income of the rural population in Northwest China,people’s sense of happiness and gain is also increasing.However,the improvement of housing conditions is lagging behind the increasing income levels.In recent years,the government and owners have paid much attention to this issue.The local government has successively issued relevant guidelines and policies to encourage owners to reconstruct their houses and improve their housing conditions.Before improving housing conditions,the existing housing problems must be identified.In order to have a comprehensive and in-depth understanding of the problems of rural residential buildings in Northwest China and to propose corresponding solutions,90 representative rural residential buildings of three provinces in Northwest China have been selected for investigation,and mass data have been obtained.Upon analyzing these data,it has been found that there are problems in five aspects of rural residential buildings in Northwest China:architectural style and functional space layout,energy utilization and dissipation,design,construction,as well as structural safety and seismic measures.Valid solutions are proposed to address these problems,which can also provide a reference for the government and enterprises engaged in the architecture,engineering,and construction(AEC)industry in rural areas.

摘要:
With the deepening of studies on metaphoric competence, the problematic definition of metaphoric competence hasincreasingly been becoming a barrier in the development of metaphoric competence studies. It is discovered that therelevant studies on the definition of metaphoric competence have ignored the essential differences betweenmetaphoric thinking way and metaphoric competence. For the solution of the problem, the corresponding measuresare proposed and the metaphoric competence is redefined as the ability that the cognitive subjects with metaphoricthinking way apply their theoretical knowledge on this thinking model into the better identification, understanding,and production of metaphor.

摘要:
With the continuous advancement of globalization and the growing international trade,international business negotiations are crucial to the success of trade.In human verbal communication,compliment is a frequently used verbal communication behavior.In business negotiations,the proper use of compliments can bring the distance between the two sides closer and create a harmonious atmosphere for negotiation.China and the United States have their own unique cultural expression patterns,so there is a huge difference in the use and response of compliments.This paper contrasts the differences in the use of compliments in Sino-US business negotiations and explores the cultural factors that produce these differences.Based on these discussions,some strategies are put forward to solve the problems occurred in the business negotiation.It is hoped that the study of this topic will help Chinese negotiators to further improve their communication skills and improve their negotiation ability so as to obtain ideal negotiation results.
