For years the English proficiency of general Hong Kongstudents is said to be continuously declining. There is a common belief that the execution of mother tongue education is a main factor for this phenomenon. However, rarely have people mentioned, discussed or thought of the relationship between the falling English proficiency and the prevalent teaching methodology. This paper questions the overuse of Communicative Language Teaching (CLT) in theHong Kongcontext. It pinpoints the key principles and features of CLT and examines the reality ofHong Kongstudents against these principles and features. It concludes through the comparison that although CLT is in vogue and meets the general desires of learning a new language, it has some limitations to a context like Hong Kong. Reality shows that CLT does not match the Hong Kong context in many aspects; overuse of it can only cause detrimental effects and fail the intended aim of using it to develop the learner’s communicative competence.
Cymbopogon citratus, better known as lemongrass, is a plant commonly used for culinary purposes.
It is known to contain the compound citronellal, which is responsible for the
lemon-scent of many of the plants of the genus Cymbopogon. A chloroform
extract of Cymbopogon citratus was screened to
determine its free radical scavenging activities. Three different methods were
used to test the antioxidant activity of the extract, including FRAP assay (Ferric reducing antioxidant potential), DPPH radical
scavenging assay (1,1-diphenyl-2-picryl hydrazyl radical reducing power methods), and β-carotene bleaching
assay. Cymbopogon citratus showed low radical scavenging activities compared to ascorbic acid, gallic acid and
quercetin. The results obtained suggest that Cymbopogon citratus is best appreciated for its refreshing aroma and delicate taste, but has
little to offer as a source of antioxidants.
