以A Special Gift为例,总结高中英语读后续写习作的常见问题,即主旨理解偏误,情节设计不符合逻辑;语言基础薄弱,出现重大语法错误;与所给短文及段落开头语衔接程度较差,上下文连贯性不强;续文内容单薄,缺乏生动、丰富的细节描写等。提...以A Special Gift为例,总结高中英语读后续写习作的常见问题,即主旨理解偏误,情节设计不符合逻辑;语言基础薄弱,出现重大语法错误;与所给短文及段落开头语衔接程度较差,上下文连贯性不强;续文内容单薄,缺乏生动、丰富的细节描写等。提出相应的教学对策:与文本深入互动,练习遣词造句,积累好词好句;提取关键词,研读提示句,合理构思情节;展示评分标准,开展评价活动,提升评价素养。展开更多
探究基于“教学评一致性”理念的高中英语读后续写教学实施路径。以A Bare-footed Old Lady为例,探讨如何将以目标为导向的“教学评一致性”理念应用于读后续写教学。提出教师应树立目标意识、提升评价素养,开展与目标相匹配的教学活动...探究基于“教学评一致性”理念的高中英语读后续写教学实施路径。以A Bare-footed Old Lady为例,探讨如何将以目标为导向的“教学评一致性”理念应用于读后续写教学。提出教师应树立目标意识、提升评价素养,开展与目标相匹配的教学活动、实施基于目标的评价,立足教学整体,使“教学评”三者实现较高的匹配度,促进“教学评一致性”的达成。展开更多
The nonlineat third order optical susceptibility of C_(60) films on roughed glass plate has been studied by using a inode locked Nd:YAG laser emitting 8ps pulsed at 1.064 μm of 0.3 J energy.The large|χ^(3)(-3ω,ω,...The nonlineat third order optical susceptibility of C_(60) films on roughed glass plate has been studied by using a inode locked Nd:YAG laser emitting 8ps pulsed at 1.064 μm of 0.3 J energy.The large|χ^(3)(-3ω,ω,ω,ω)|=2 ×10^(-8) esu for C_(60) films of 15μm thickness has been observed,which is 1O^(3) larger than the value in the bulk C_(60).This is due to surface enhanced effect.展开更多
