Research on the Reform Path of Ideological and Political Education in Tourism English Courses in Higher Vocational Education

Tourism English in higher vocational education has profound humanistic,strong professional orientation,and instrumental characteristics.Through analyzing the current situation of ideological and political teaching in Tourism English courses in higher vocational education,it is found that there are too few ideological and political elements in the curriculum,the skills teaching and ideological education are not unified,and the ideological and political education in the curriculum tends to be empty preaching.The reasons for this are the weak ideological and political awareness of teachers,the emphasis on skills in textbooks over ideological and political education,and the conservatism of teaching methods.Based on the requirements of curriculum ideological and political education and teaching reform,a teaching reform practice path is constructed from four aspects:anchoring curriculum ideological and political goals,improving teachers’ideological and political awareness and educational ability,creating ideological and political-oriented textbook resources,and integrating ideological and political teaching methods through multiple channels throughout the entire process,in order to cultivate students with patriotism,international vision,and professional skills.

Calcium-catalyzed reactions of element-H bonds

Investigation on organocalcium catalysis is just unfolding during the past decade. Beside conventional Ca salts with strong electron-withdrawing counter anions that may serve as Lewis acid catalysts, many Ca complexes have also been designed recently and found to be good catalysts in activation of element-H （E-H） bonds like transition metal catalysts. These findings are interesting and may attract the interest of the chemists. Due to the great abundance, non-toxicity, and biocompatible features of Ca element, Ca-catalyzed reactions can be of great significance from the viewpoint of industry. This short review summarizes the recent advances on Ca-catalyzed reactions of E-H bonds. We hope that it may provide a useful guide for interested readers from both the academy and industry.

Organotellurium-catalyzed oxidative deoximation reactions using visible-light as the precise driving energy

Irradiated by visible light,the recyclable(PhTe)2-catalyzed oxidative deoximation reaction could occur under mild conditions.In comparison with the thermo reaction,the method employed reduced catalyst loading(1 mol%vs.2.5 mol%),but afforded elevated product yields with expanded substrate scope.This work demonstrated that for the organotellurium-catalyzed reactions,visible light might be an even mo re precise driving energy than heating because it could break the Te—Te bond accurately to generate the active free radical catalytic intermediates without damaging the fragile substituents(e.g.,heterocycles)of substrates.The use of O_(2) instead of explosive H_(2)O_(2) as oxidant affords safer reaction conditions from the large-scale application viewpoint.
