认知语境视角下英语句法歧义句的意义建构

以90名全日制大一学生为受试,运用基于选择和翻译两个任务的句法阅读测试,对认知语境在句法歧义句意义建构中的作用进行了研究。综合阅读测试、有声思维和访谈等三种研究方法所得出的结果表明:语言知识、情景知识和背景知识的内化能够加速句法歧义句的理解;共有的认知语境能够促进句法歧义句的意义建构;此外,认知语境会使句子理解的最大关联和最佳关联之间形成反差,从而限制歧义句的理解。最后提出,广大外语教师应该积极利用多媒体技术和教学环境,尽可能地扩大学生的认知语境,从而提高学生句法阅读的能力,继而提高篇章理解的能力。     

Numbers,scale and symbols: the public understanding of nanotechnology

Nanotechnology will be an increasing part of the everyday lives of most people in the world. There is a general recognition that few people understand the implications of the technology, the technology itself or even the definition of the word. This lack of understanding stems from a lack of knowledge about science in general but more specifically difficulty in grasping the size scale and symbolism of nanotechnology. A potential key to informing the general public is establishing the ability to comprehend the scale of nanotechnology. Transitioning from the macro to the nanoscale seems to require an ability to comprehend scales of one-billion. Scaling is a skill not common in most individuals and tests of their ability to extrapolate size based upon scaling a common object demonstrates that most individuals cannot scale to the extent needed to make the transition to nanoscale. Symbolism is another important vehicle to providing the general public with a basis to understand the concepts of nanotechnology. With increasing age, individuals are able to draw representations of atomic scale objects, but these tend to be iconic and the different representations not easily translated. Ball and stick models are most recognized by the public, which provides an opportunity to present not only useful symbolism but also a reference point for the atomic scale.

An Energy-Aware Routing Protocol Based on Effective Transmission in Sensor Networks

In order to minimize the energy consumption in the discovery of the routing path, this paper introduces a novel concept of effective transmission （ET） that ensures each forwarding node is not only farther from the source node, but also nearer to the destination node with respect to its sender, An energ-aware routing protocol based on ET is proposed. It enables the energy consumption for each hop to be the least for the transmission. The simulation results show the routing protocol is effective in the performance of energy consumption comparing with some other routing protocols.     

公众环保意识与三峡库区的环境保护

2003年6月开始蓄水后，三峡库区江段水面将扩大，水深增加，江水流速变缓，库区的生态环境将面临更大的威胁，只有使库区的环境危机真正根植入公众心中，才能提高公众的环保意识和参与意识，从而保护库 区的生态环境。

"数学生活化"与数学教学

数学在越来越生活化——即数学知识越来越广泛地运用到了社会生活中的方方面面。数学的生活化体现了数学的工具性，我们应强化数学意识，充分发挥数学的工具性作用。     

道德、法律与公民意识

自改革开放以来,我国在一直大力加强法制建设的同时却忽视了道德秩序的建立。面对社会现在的“道德危机”和“法律纸面化”问题,我们必须提高道德与法律的内化力－公民意识。采取灵活多样的有效形式,推进中国法治现代化进程。
