The purpose of employing multi-media technology is to encourage students＇ class participation, giving them explicit and specific impression of abstract contents and cultivating their intuitive grasp of linguistic points. Based on the current study of usage of multi-media technology in class teaching, this paper attempts to investigate mainly on its positive influence of multi-media technology in teaching.展开更多

The modem multi-media technology features the integration of the audio and video technologies and the simultaneous use of eyes and hands, embodies the inherent inspiration for its simulation, feedback, games, etc., and emanates enormous appeal. Its dynamic integration with physical education brings about a brand-new education approach in the history of physical education reformation. It has been involving to be an important education approach for PE teachers. Nevertheless, there are still a lot of key and difficult points that are not easy for the students to grasp regarding the application of modem multi-media technology to the physical education; and the teachers are weak in this new education approach and their course preparations are of low quality. Therefore, more attention needs to be paid to the integration of the advantages of multi-media teaching and the peculiarities of physical education so that multi-media technology can be made the best use in physical education.展开更多

The results revealed that soils in the area studied have been heavily polluted by Cd, Zn, Pb and Hg, and the levels of these metals in the samples of agricultural crop greatly exceed the standards. The above-mentioned pollutants exist in all soil-multi-media environments. The mullock, slag, wastewater, surface water, ground water, soil, and agricultural crops constitute a composite ecological chain. Therefore, the improper disposal of mullock and slag, and the use of polluted wastewater for agricultural irrigation are the main causes of soil pollution. Heavy metals in the soil have three transition progresses: point (improved soil with slag, ground water inflow plot), linear (river transition) and non-point transition (regional pollution by slag) patterns, and the tailing yard is the most important locus for heavy metals to release into the environment.展开更多
