The purpose of this study is to examine what factors make listening difficult in English education and suggest some principles for teaching English listening skills. The eight characteristics of spoken language are adapted from several sources: clustering, redundancy, reduced forms, performance variables, colloquial language, rate of delivery, stress, rhythm, intonation, and interaction. There are some principles for teaching listening skills: 1) include a focus on listening in an...

Culture influences the teaching of English to speakers of other languages in six basic ways. Each can become a component of instruction. First, the learner has learned how to learn by means of native culture patterns, values, and behaviors. Second, the intercultural educator accommodates to students' culturally derived learning styles and strategies in order to deliver effective instruction. Third, learning a language becomes easier when the whole personality of the learner is engaged. Fourth,...

with a 0.1% Ni-Fe catalyst at 450℃. The surface area of Chestnut-like carbons were 2401 m2/g. Additional specific capacitances of Chestnut-like carbon are significantly higher than those of other activated carbons. Chestnut-like carbon electrodes show approximately 44% retention of the specific capacitance, which is higher than that of the virginity activated carbon. Thus, Chestnut-like carbon electrode can be predicted to yield better performance in the capacitive deionization (CDI) process.

was also very sensitive at space velocity, O2 concentration, and NH3/NO ratio. It was found that the maximum conversion temperature of (W, Mo, Sn)-V2O5/TiO2 catalysts was broaden. Specially WO3-V2O5/TiO2 catalyst appeared nearly 100% conversion at not only above 300℃ but also below temperature of 25 0℃. At over 300℃, NH3 oxidation was decreased as decreasing of surface excess oxygen. Also WO3-V2O5/TiO2 catalyst does hardly appear to effect on space velocity, O2 concentration and NH3/NO ratio.

Particulate matter research is of great significance in solving atmospheric environment problems. The heterogeneous reaction of mixed gas on different mineral oxides and coal ash was studied based on a laboratory-built aerosol generating reactor. The product formed on particles was investigated by ion chromatography (IC). SO2 and NO2 could react on oxides to form secondary particles and the order of reactivity of mineral oxides under laboratory reaction conditions is: Al2O3>MgO>CaO>>SiO2, Fe2O3....

The surface discharge induced plasma chemical process(SPCP) was applied to decompose nitric oxide(NO). The operating condition was optimized in order to maximize the NO decomposition efficiency. The highest NO decomposition efficiency obtained was 94.3% at the power consumption of 19.8 W for the frequency of 10 kHz. NO decomposition efficiency increased with increasing residence time or with decreasing initial concentration of NO. As the thickness and melting point of the electrode increased,...
