Between 2000 and 2017, deaths resulting from AD increased 145%. Based on the latest statistical data, more than 50 million people in the world suffered this devastating disease, which is one of major burdens in modern public health system(Alzheimer's Association, 2020).展开更多

On June 27th, the China Construction Ministry (CCM) announced that China will intensify efforts to implement the supervision of construction standards with the goal of promoting energy saving practices. By 2010, urban construction projects are expected to achieve energy savings of 50%, and by 2020 to save 351 million tons of coal.……展开更多

So if in the language learning and teaching, attention is only paid to the linguistic forms but the relationship between language and culture is ignored, then the learner's linguistic ability will not be equivalent to his or her social and cultural communication competence. Especially in the times of globalization with increasing transna tional and cross-cultural communication, the knowledge of cultural background is the must prerequisite for not only the avoidance of cul tural "conflict" but the success of communication. Based on the studies of several cross-cultural communication cases and the analysis of the relationship between language and culture, including the famous Sapir-Whorf hypothesis, this paper is aimed to analyze the intrinsic and in dispensable relationship between language learning and culture learning.展开更多
