正我在冬天的"东哈莱姆"住下,在五条大道和四十多条街巷的阡陌里,包裹严实地逛荡了三个月。每个"扫街"回来的傍晚,从纽约地铁6号线110街站台出到地面,我总遇到把在出口问行人讨要一美元的那个中年妇女,对面街口常在的是一个拄着拐杖要咖啡钱的白胡子男人。他们的背后,杂货店门上显眼的位置贴着"接受电子福利转账(EBT accepted,作者注:困难群体在美国"食物保障计划"支持下可以通过福利卡转账获得免费食物)"几个大字,熟食店晃眼的灯泡照在一列列炸鸡腿上,面包店里的杯形蛋糕装饰着过分艳丽的奶油。在肤色暗沉操着西班牙语的人流里,我总会莫名的想起七十年前的加缪。和他一样,我只是个"局外人",游弋在这座岛屿上恐怕仍旧"最暗淡无光的地方"。 相似文献

The period from Arthur Clarke's 1945 prediction of geosynchronous satellite communications covering the entire planet until satellites were stationed over the Atlantic, Pacific, and Indian Oceans was less than 25 years. In the following 15 year period, satellite communications has affected all of us. Most international calls are carried by satellite. Much of the television that we watch has been relayed, processed, or distributed by satellite. In fact, many of us who live in cabled cities can choose among 50 channels or more for viewing on a particular night, largely brought to us by satellite. Some morning papers, radio programs, and basic weather data appear coast to coast rapidly because of the satellite. Even while we sleep, computers in an increasing number of business offices are talking to each other by satellite. Virtually the whole world, from the busiest urban center to the most remote island, can be interconnected by satellite communications networks capable of providing economical and reliable transmission of communications signals, including voice, data, electronic mail, and video. The satellite's advantages of distance insensitivity, point-to-multipoint capability, and improved quality over long distances are unique. These facts have led Clarke to speculate on the future impact of satellite communications in The View from Serendip (1977): I submit . . . that the eventual impact of the communications satellite upon the whole human race will be at least as great as that of the telephone upon the so-called developed societies. 相似文献

中式英语是英语学习过程中出现的具有汉语特色的畸形英语,它不仅表现在语音、语义方面,还表现在句法、语用等层面。导致中式英语的因素很多,其中最主要的就是母语负迁移的影响、思维方式的差异、中西文化不同以及双语能力的欠缺。中式英语会对交流起阻碍作用,因此要采取适当的措施,尽最大可能减少交际过程中中式英语的产生。 相似文献

语言与文化的关系密不可分,只学习语言本身,缺少对外语文化的了解已不能适应目前跨文化交际的需求。作为大学英语教师,不能忽视文化语境的教学,文化语境的建构和提高大学生跨文化交际能力正是项目的研究目的。从提高大学生跨文化交际的必要性、方法,及如何在课堂上灌输文化教学的实践基础出发,为大学英语教师适应新时代的大学英语教学提供借鉴。 相似文献

One of the fundamental challenges facing the scientific community as we enter this new century of Mars research is to understand, in a rigorous manner, the biotic potential both past and present of this outermost terrestrial-like planet in our solar system. Urey: Mars Organic and Oxidant Detector has been selected for the Pasteur payload of the European Space Agency’s (ESA’s) ExoMars rover mission and is considered a fundamental instrument to achieve the mission’s scientific objectives. The instrument is named Urey in recognition of Harold Clayton Urey’s seminal contributions to cosmochemistry, geochemistry, and the study of the origin of life. The overall goal of Urey is to search for organic compounds directly in the regolith of Mars and to assess their origin. Urey will perform a groundbreaking investigation of the Martian environment that will involve searching for organic compounds indicative of life and prebiotic chemistry at a sensitivity many orders of magnitude greater than Viking or other in situ organic detection systems. Urey will perform the first in situ search for key classes of organic molecules using state-of-the-art analytical methods that provide part-per-trillion sensitivity. It will ascertain whether any of these molecules are abiotic or biotic in origin and will evaluate the survival potential of organic compounds in the environment using state-of-the-art chemoresistor oxidant sensors. 相似文献
