It also focuses on its function in an EFL curriculum concerning of raising intercultural awareness and training intercultural competence. In the process of instruction, students are supposed to be exposed to multicul-tural contents and various culture input. To achieve this goal, it is necessary to develop a well-tailored ILE curriculum and textbooks. This article is to review Wang and Zhou's points critically. Thus, it can evoke the awareness of course designers to attach the importance of ILT and call for relevant actions.展开更多

Although the plant is thought to have been present in Nigeria for well over two decades, its mode and time of introduction is uncertain. In spite of the continuing spread of, and the menace caused by M. diplotricha in Nigeria, no attempt has been made to map the distribution of the plant countrywide. Therefore, we conducted a countrywide survey between 2007 and 2009, sponsored by the Weed Science Society of Nigeria (WSSN) to determine the spread and status of Mimosa diplotricha in Nigeria. A further objective of this paper was to review literatures on Mimosa diplotricha in Nigeria and elsewhere to enable comparison. In this paper, we report on the spread, distribution and problems of Mimosa diplotricha in Nigeria based on the field monitoring surveys conducted. The distribution of this invasive plant in Nigeria has been mapped and is presented together with its ecology and problems being caused. Since the early 1990s, the weed has started to spread and invade many parts of the country causing significant damage to many natural and semi natural ecosystems. The different control options used by farmers to control Mimosa diplotricha in Nigeria are discussed. Based on the successful control of this invasive plant using the biocontrol agent, Heteropsylla spinulosa in countries such as Australia and Papua New Guinea (PNG), we discussed the biological control prospects for the management of Mimosa diplotricha in Nigeria. Such control attempts stands to benefit from international collaborations between Nigerian institutions and a host of others in Australia, PNG and/or Brazil. Finally three major causes for the massive and continuing spread of this weed in Nigeria are presented with recommendations for the Nigerian government and institutions to: 1) formulate policies and legislations regarding the control and management of invasive alien plant species which is currently nonexistent;2) enlighten the general public on the dangers of invasive alien plant species such as Mimosa diplotricha;and 3) initiate actions such as early detection and rapid response (EDRR) and biological control in order to prevent further spread of, and invasion by invasive plant species including Mimosa diplotricha.展开更多

It has a positive effect on promoting economic development and helping farmers to get out of poverty in Guangxi. But there is almost nothing to do with the processing and utilization. Taking the route of processing and utilization is an inevitable trend of development of Longtan pearl plum industry with the increase of the planting area and yield year by year. In this paper, based on the analysis of edible value of Longtan pearl plum, the development direction of processing and utilization of Longtan pearl plum was expounded, and some suggestions on the problems existing in the processing and utilization were put forward to provide reference for the processing and utilization of Longtan pearl plum.展开更多
