诗歌是隐喻的海洋。中国古典诗歌是世界文化宝库中的一朵奇葩,它既是中国语言的精华,更是中国文化的结晶,其中包含了丰富的隐喻。隐喻反映文化,中国古典诗歌中的隐喻蕴涵着丰富的文化内涵。关于诗歌的翻译,目前主要是从跨文化的角度来进行探讨的较多,本文正是基于跨文化的视角,进而从文化语境动态顺应的角度来探讨中国古典诗歌中隐喻语义的翻译策略,期望其对中国古典诗歌中隐喻语义的翻译理论与实践有所裨益。 相似文献

Although several antiviral drugs and vaccines are available for use against hepatitis B virus (HBV), hepatitis caused by HBV remains a major public health problem worldwide, which has not yet been resolved, and new anti-HBV drugs are in great demand. The present study was performed to investigate the anti-HBV activity of epigallocatechin-3-gallate (EGCG), a natural-origin compound, in HepG2 2.2.15 cells. The antiviral activity of EGCG was examined by detecting the levels of HBsAg and HBeAg in the supernatant and extracellular HBV DNA. EGCG effectively suppressed the secretion of HBsAg and HBeAg from HepG2 2.2.15 cells in a dose- and time-dependent manner, and it showed stronger effects at the level of 0.11–0.44 μmol/ml (50–200 μg/ml) than lamivudine (3TC) at 0.87 μmol/ml (200 μg/ml). EGCG also suppressed the amount of extracellular HBV DNA. The data indicated that EGCG possessed anti-HBV activity and suggested the potential of EGCG as an effective anti-HBV agent with low toxicity. 相似文献

苏轼与贺铸为豪放词作的典型代表,由于二人生活背景及当时北宋重文抑武政策的影响,产生了二人完全不同的人生命运。《定风波》和《六州歌头》分别代表了两人不同的词风特点及人生态度,比较这两首词可得出影响二人词风的重要因素。 相似文献

Streptomyces produces many valuable and important biomolecules with clinical and pharmaceutical applications. The development of simple and highly efficient gene editing tools for genetic modification of Streptomyces is highly desirable. In this study, we developed a screening system for targeted gene knockout using a uracil auxotrophic host(Δpyr F) resistant to the highly toxic uracil analog of 5-fluoroorotic acid(5-FOA) converted by Pyr F, and a non-replicative vector p KC1132-pyr F carrying the complemented pyr F gene coding for orotidine-5'-phosphate decarboxylase. The pyr F gene acts as a positive selection and counterselection marker for recombinants during genetic modifications. Single-crossover homologous integration mutants were selected on minimal medium without uracil by reintroducing pyr F along with p KC1132-pyr F into the genome of the mutant Δpyr F at the targeted locus. Double-crossover recombinants were generated, from which the pyr F gene, plasmid backbone, and targeted gene were excised through homologous recombination exchange. These recombinants were rapidly screened by the counterselection agent, 5-FOA. We demonstrated the feasibility and advantage of using this pyr F-based screening system through deleting the otc R gene, which encodes the cluster-situated regulator that directly activates oxytetracycline biosynthesis in Streptomyces rimosus M4018. This system provides a new genetic tool for investigating the genetic characteristics of Streptomyces species. 相似文献

This paper examined the debate on a reform of school-based management in Hong Kong, which was to set up the Incorporated Management
Committee (IMC) to manage the subsidized school. The nature of the debate during legislation and the characteristics of the
reform were examined. The advantages, disadvantages and the implications of the reform were discussed. The major concerns
of various actors were found to include the control of schools, the mode of participation and the barriers to implementation.
It was suggested that via the legislated reform, the control of subsidized schools in Hong Kong will be shifted from “a specific
type of community control” to “equal control.” In contrast to some reforms of School Based Management overseas, there has
been no decentralizing of power on the part of Government in this exercise. In the opposite, it was argued that by requiring
the school sponsoring body to set up the independent IMC and to divide its power of among various stakeholders, the Government
would assume increased control in school education. 相似文献
