A Probe into Some Aspects in China's Foreign Language Curriculum

—"Where do I begin?"The place to begin is with your own assumptions about what students should learn and how they learn best.Curriculum plans are most likely to be acted on when their assumptions coincide with the teacher’s ideas about learning.When teachers are required to use plans whose assumptions differ from their own,they adapt them to suit their own purposes.

Evaluation of Sustainable Factors in the Chinese Construction Process

The building sector plays a key role in the global economic,social,and environment development.The energy consumed during construction and operation processes accounts for around 40%of the global energy use.China is the largest developing country and its construction market is one of the largest markets in the world.Although the construction phase occupies only a short period over the entire life cycle of a building,it is still an essential aspect of the process.However,in China,the concept of green construction remains scarcely known among construction industry members.Green construction continues to experience a disparity in the Chinese construction industry.Therefore,the aim of this study is to appraise the concept of green construction in the Chinese construction industry and to consider how it could be applied in most Chinese construction projects.

基于MODIS数据的2003—2020年西南地区林火随地形因子的动态变化

云南、贵州、四川、重庆为代表的西南地区是我国第二大天然林区,是我国林火灾害最严重地区之一。研究气候变化下该地区林火分布的地形变化规律,可为天然林应对气候变化提供科学依据。基于2003—2020年MODIS火点数据MCD14DL,结合地理高程数据DEM和历史气候数据,运用数理统计、核密度分析和M-K趋势检验,研究气候变化下西南地区林火与地形因子的统计关系及变化趋势。研究表明:(1)2003—2020年西南林火总体呈下降趋势,下降率为42次·a^(-1)。春、冬季为林火高发期。空间上总体呈现从云南南部到四川北部逐步减少的格局,林火分布多集中在哀牢山、横断山脉以及攀枝花等地。(2)2003—2020年平均来看,林火与海拔、坡度呈单峰型关系,分别在海拔1400—1600 m、坡度15—20°达到峰值;阳坡最多,半阴半阳坡最少。(3)气候变化下,林火出现“转移”现象。海拔600—1200 m内相对湿度和降水的增加致使林火在该海拔显著减少、在高于1400 m的中高海拔区间增加;年均温的升高导致林火从坡度20—25°“抬升”到35°以上。气候变化下,西南林火出现向高海拔、高坡度转移现象,致使高海拔、高坡度可燃性屏障减弱。

晚清来华西人对塾师的多维书写与形象建构研究

晚清时期,来华西人出于政治考量、文化输出、传教需求等多种因素,对中国塾师群体给予了广泛的关注与书写,以满足对华认知的整体诉求,进而建构了塾师多维的“他塑形象”。19世纪早期至60年代以前是描述性介绍为主的早期阶段,主要关注塾师的经济状况、教学教法,是为获取对华认知信息服务,而主观性的文化价值判断色彩较弱;19世纪60年代至20世纪初,则对塾师进行了全方位观察与多维度书写,以文化价值判断为主导,运用特异化手法,建构了塾师“一体多面”的形象,呈现出塾师“专业素养不甚高明”的职业形象、“贫寒”的经济形象、“特异化”的外貌形象、“无知、疏懒、严厉”的人格形象。在塾师“一体多面”的形象之下,隐含了西方中心主义价值取向。而解构中国传统教育,最终以现实为指向则是晚清来华西人塑造塾师形象的重要文化动机。晚清来华西人主要通过倾向性地择取“写实”要素,运用特异化手法和构建微型教学展示空间,对塾师进行形象建构。作为异域文化的观察者,来华西人的塾师书写虽然存在歪曲和想像,却在一定程度上为观察中国传统教育提供了多维视角,促使国人从“他者”视域反思中国本土教育问题。

Among 33 cold frontal systems passed over the Beijing-Tianjin-Tangshan area from May to August during 1963—1979,there existed mesoscale rainbands in the warm sectors ahead of 31 cold fronts.These rainbands, according to their orientation,movement,formation and development,can be divided into three types:parallel, angulate and perpendicular type.The basic characteristics,sources and propagation of the three types of rainbands and the severe convective weather associated with the bands are presented.The possible mechanis- ms responsible for the formation and development of the bands are also briefly discussed.

大学先行——中国共产党发展教育的基本策略

教育发展策略选择是影响教育成效的重要因素,同时也反映了发展主体的认识能力。文章运用历史研究法对中国共产党成立100多年来发展教育的历程进行考察发现,中国共产党始终坚持大学先行的基本策略,充分发挥大学在教育事业发展中的先导性、示范性和战略性作用,取得了显著成效。中国共产党大学先行策略的选择依次体现出自发、自觉、自动和自主的阶段性特点,说明中国共产党对大学先行发展的认识能力不断提高,且能根据形势和任务的变化调整大学先行的内容和方式。中国共产党选择大学先行的基本策略除了有阶段性的背景和原因之外,还在于其所坚持的世界观和方法论、对教育历史发展传统的承继和对后发国家教育发展道路的探索。新时代中国式教育现代化的推进应继续坚持大学先行策略,注意把握好大学的发展次序、发展保障和发展地位。

“三个务必”的生成逻辑、核心要义与实践要求

“三个务必”是新时代中国共产党“走好新的赶考之路”的政治宣言和行动纲领,科学回答了“建设什么样的长期执政的马克思主义政党、怎样建设长期执政的马克思主义政党”这一重大时代课题,其形成有着深刻的理论逻辑、历史逻辑和现实逻辑。三个“务必”之间价值同向、逻辑互补、相辅相成,分别从根本要求、作风保障、动力支撑三个方面阐释了建设长期执政的马克思主义政党应强化什么样的政治自觉、保持什么样的政治品格、具备什么样的政治能力的问题,是马克思主义中国化时代化的理论创新。践行“三个务必”,必须以坚持人民群众的主体地位为根本、以推动马克思主义守正创新为前提、以加强党的组织队伍建设为重点、以完善管党治党的体制机制为关键,推进以党的自我革命引领社会革命的伟大实践。

东海陆架盆地西湖凹陷中央反转构造带古近系花港组气藏“先汇后聚”机制及地质意义

反转构造带作为圈闭发育的优势构造带在国内外诸多盆地已揭示了丰富的油气资源,但对于海上盆地来说,由于钻井成本较高、钻井较少,对反转构造带油气成藏规律的研究相对薄弱。以西湖凹陷中央反转构造带为例,重点关注烃源岩层系内部的原始汇烃能力及从源到储的动态油气富集过程,以期揭示反转构造带油气富集规律。通过构造演化史-生烃演化史-储层演化史-油气充注史匹配关系分析认为,西湖凹陷中央反转构造带北部地区烃源岩大量生烃期和油气充注时间早于圈闭形成时间,早期天然气在源内层系先形成聚集气或丰度较高的“半聚集”气,即“先汇”;晚期构造运动伴随圈闭形成使得早期气向上运移至圈闭中聚集成藏,即“后聚”,成藏后表现为天然气成熟度由深向浅呈增大的趋势。因此提出“先汇后聚”成藏新机制,该机制不仅阐释了源上古近系花港组主力勘探层系生烃期-圈闭形成期-油气充注期时间不匹配的问题,而且揭示了源内古构造背景对源上现今油气成藏富集的控制作用。在该模式指导下指出了中央构造带大型圈闭天然气成藏的关键因素,并提出B构造具备良好的“先汇后聚”条件。“先汇后聚”成藏模式具有一定普遍性,不仅对西湖凹陷中央反转构造带油气勘探具有指导作用,对有类似地质条件的含油气盆地油气勘探亦具有重要借鉴意义。

20世纪90年代以来东北暴雨过程特征分析

使用1990～2005年全国730站日降水资料和NCEP格点分析资料对1990～2005年东北地区大暴雨过程进行了分类研究,探讨21世纪前后夏季东北暴雨的主要特征。按照东北地区日降雨量大于50 mm的站点数不少于5个的标准,统计出1990～2005年东北地区的69个暴雨个例(共90天)。在统计的基础上,进一步对造成大范围暴雨过程的天气形势进行分类研究。考虑阻塞高压、热带、副热带系统和西风带之间的相互关系,将暴雨过程的主要影响系统大致分为6类:(1)台风与西风带系统(西风槽、东北低涡)的远距离相互作用(20个,28.9%);(2)登陆台风(或南来低涡)北上与西风带系统(西风槽、东北低涡)相互作用(16个,23.2%);(3)台风直接暴雨(1个,1.5%);(4)低槽冷锋暴雨(16个,23.2%);(5)低空切变型暴雨(2个,2.9%);(6)东北低涡暴雨(14个,20.3%)。在所有个例中与台风有关的共有37个,超过一半,占总数53.6%。台风的远距离水汽输送或登陆台风北上与西风带系统相互作用是东北地区产生大暴雨或持续性大暴雨的重要环流条件。此外,东北低涡和西风槽前系统造成暴雨个例也比较多,也是东北地区大范围暴雨的重要影响系统,低槽冷锋暴雨和东北低涡暴雨也各分为4小类。低空切变暴雨的切变线一般在低层较为明显。上述分析表明,夏季东北地区暴雨过程种类繁多,情况较为复杂,且进入新世纪以来该区降雨过程较为活跃,值得深入研究。
