简介:particularly English language proficiency tests. What’s at issue here is not ‘globalization or localization,Yang (2004) argues for localization of English language tests,with no steady trend of localization. GEPT is the first large-scale proficiency test ever developed by local professionals in Taiwan. What distinguishes it from international tests is its claims and practice of localization
简介:a small set of international English language proficiency tests such as TOEFL and IELTS is developing with great momentum. Test localization,and one cannot replace the other. Notwithstanding his strong arguments for localizing language tests Yang (2004) acknowledges that developing a test on the intercultural norm does not mean eradication of the native speaker norm or complete localization of the test,if one test is carried out to assess the English language proficiency of students from other countries
简介:三新奇Ba_5RNiNb_9O_(30)(R=La,Nd和Sm)陶艺在BaO-R_2O_3-NiO-Nb_2O_5系统被准备并且描绘。所有三混合物areparaelectjicphasesadopting。在房间温度的充满的四角形的钨铜(TB)结构。在1MHz,Ba_5RNiNb_9O_(30)陶艺有高电介质在范围193-245.3,在范围0.0059-0.0087的低绝缘的损失,和在范围的绝缘的常数(tau_e)的温度系数的常数-1140-1310X10~(-6)中心点degC。他们绝缘的常数的温度系数显著地Ba_5RNiNb_9O_(30)与那些相比被减少(R=La,Nd,Sm)陶艺。
简介:(N-isopropylacrylamide)(PNIPAM)Poly,microgels广泛地在药交货被使用由于他们对温度的快反应。以便得到更好的biocompatibility,PNIPAMmicrogels与biocompatible材料的层典型地是涂的,与核心壳导致合成microgels结构。例如,在最近准备的合成microgel,PNIPAM胶化的microsphere被phospholipid膜围住,并且合成microgel响应温度变化展出实质的音量转变。这里,我们开发一个理论模型描述这合成microgel的热应答的行为。特别地,我们把phospholipid膜当作象橡皮状的弹性体一样表现的有弹性的层并且为nematic胶化采用免费精力的功能的形式(它指其行为强烈地被学习了的热敏感的胶化的花药种类)作为那为PNIPAM胶化。我们证明合成microgel的热应答的行为能被膜显著地影响。由在接口上调查应力的状态,我们进一步预言当涂层膜生硬、薄时,皱纹被期望在卷转变以后发生在合成microgel的外部表面上。
简介:摘要:为了适应新高考,满足英语教育的未来发展趋势,越来越多高中英语教师开始重视培养学生概要写作能力,但总体来看效果并不理想,大多学生还不善于总结与概括,无法准确筛选关键的文本信息并转化为写作语言,甚至直接抄写原句凑字数的行为也不在少数。为了改变这一状况,笔者在高中英语概要写作课堂教学中引入了“ I-R-O模式”,即循序渐进地引导阅读与写作思路,完成语言“输入 -重组 -输出”,强化英语语言实践运用能力。
