In response to these changes, this paper claims that the teaching of English pronunciation and intonation in China should be more inclusive. Specifically, we should transcend the nativeness paradigm, add in some widely recognized EIL phonetic features, enhance students' receptive skills, help students grasp the essence of the Lingua Franca Core, innovate the present assessment of learners' pronunciation and intonation, and put more emphasis on teacher education to keep up with this latest trend.
基于这些新形势和新的研究成果,中国高校英语语音教学应突破本族语言范式,适当添加国际广泛认可的EIL的一些主要语音特征,提高学生对不同母语的英语使用者语音的辨识能力和接受性技能,着重帮助学生克服核心语音等容易影响交流的语音错误,改革语音考核制度,并且加大对语音教师有针对性的培训。

Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.

Culture tender leaves in culture medium of MS+2,4-D1.5mg/L+30g/L suger+0.7% agar pH5.8 for 20 days in darkness at 25℃, and then subculture to induced Ⅱ-type calli. Use forceps cutting the tissue to nubble with 2mm2, and put the tissue into Agrodacterium tumefaciens LBA4404 liquid supplemented with AS 100mg/L,then, co-culture 3 days, resume 7 days in MS+2,4-D1.5mg/L+30g/L suger+500mg/L cef, take to MS+2,4-D1.5mg/L+30g/L suger+100mg/L cef+10.0mg/L kanamycin culture 20 days in darkness. After that to make it polarize in MS+30g/L suger+100mg/L cef+10.0mg/L km. The percentage of km resistant callus was reached max after infection for 45 min, the average is 29.66%. Simultaneity, tender leave callus are infected 5 min by A. tumefaciens liquid in different negative pressure, and kept on 15 min in Agrodacterium tumefaciens liquid without negative pressure. Then screen out resistant callus and obtain transgenic plants. When the negative pressure is -0.05MP the percentage of km resistant callus was reached max, the average rate is 37.5%.
