Unreasonable carbon BRICS appear in the process of economic growth in the emission of the negative externalities of the typical characteristics, needs under the government strong interference can be effectively controlled. In this paper, we study the relationship between environmental quality and economic development of the BRICS by using the semi parametric regression model, and explore the effective path to promote the coordinated development of economy and environment in the BRIC countries by introducing relevant control variables to determine the main influencing factors of EKC. The results show that: most of the BRIC countries in the environmental quality and economic growth in the presence of decoupling phenomenon; due to the industrial structure, urbanization and energy consumption and other aspects of the existence of irrational phenomenon to reduce the environmental quality; The promotion of sustainable development helps to improve environmental quality and promote economic development. The policy recommendations of this research is that the BRICS should pay more attention to the quality of economic development and energy saving and emission reduction work, and should adopt the strong low-carbon technology development and application of financial investment, promote the construction of ecological civilization, strengthen international cooperation, strengthen supervision and law enforcement efforts and other measures to achieve sustainable development goals.

With relevance theory and coherence theory as the theoretical basis, this paper studies the pragmatic function of Chinese-Utterance final particles: a, ba and ne and claims that the discourse function of ne is stronger than a and ba. In other words, the modality meaning of a and ba is stronger than ne. This paper also studies the reason why a, ba and ne have different pragmatic functions and concludes that the meaning of ne is mainly the meaning of mood, ne has a longer history and the grammaticalization of ne is more complete while a and ba have obvious modality meaning; they have a shorter history than ne as mood particles and their grammaticalization still continues.

The relationship between Li Qingzhao and Buddhism has been less concerned. Self‐titled Yi’an Jushi,it couldn’t just be the reason of self‐loftiness. From the research of existing historical data, family misfortune, seedless and the influence of friends and family were the main reasons made Li Qingzhao approached to Buddhism. From the use of her Ci‐poetry allusion, imagery and realm,we can also find Li Qingzhao’s attitude about Buddhism. And with a new view of Buddhism, the problems such as the choice of imagery, the method of rhetoric and the style of Li Qingzhao’s Ci‐poems can be interpreted in a new way. Because of her unique life experience, Li Qingzhao approached Buddhism to relief the pain of life, and organic merged Buddhist thought into her works. The sadness and beauty of Li Qingzhao’s works just come from this. So, “Li Qingzhao’s indifference to Religion” is worth discussing, and the relationship between female Buddhist literati and Buddhism is still a subject worthy of further exploration and study.
