基于学习者英汉平行语料库的情态动词研究——以情态动词“must”为例     

谢家成 《荆州师范学院学报》2009,(6):58-61

学习者英汉平行语料库为情态动词等中介语研究提供了两个考察视角,即中介语视角和相应的学习者母语视角。以情态动词“must”为例,从中介语视角考察,通过检索自建的学习者英汉平行语料库,发现中国英语学习者较多使用情态动词“must”的义务情态意义及其序列,认识情态意义及其序列的使用频率则相对较少且错误较多。从学习者母语视角考察既包括分析与情态动词“must”相对应的汉语部分,也包括检索汉语“必须”这一情态表达的相应英语。调查发现,双语转换时母语思维对英语情态动词“must”的习得有影响,但并不显著,对相关情态动词或情态性的运用掌握不足可能是更重要的原因。调查展示了学习者英汉平行语料库对中介语研究的巨大潜能。  相似文献   

轶事与宏大叙事的对立与统一——《史记》和《名人传》轶事观念之比较     

王成军 《西南师范大学学报(人文社会科学版)》2010,(1):171-177

轶事观是司马迁和普鲁塔克传记方法论的重要组成部分。普鲁塔克将轶事作为刻画传主的性格和心理的主要手段,其趋向使轶事与宏大叙事对立起来;司马迁则在轶事作为揭示传主性格和心理手段的基础上,着意将轶事与宏大叙事在对立中又统一起来,表现出将传主的性格和心理同传主真实而丰富的人生历程、社会历史的进程相结合的趋向。对二者轶闻趣事观念的研究对于推动现代传记史学的发展具有重要借鉴意义。  相似文献   

Parallel processing architecture of H.264 adaptive deblocking filters     

Hu Wei  Tao Lin  Zheng-hui Lin 《浙江大学学报(A卷英文版)》2009,10(8):1160-1168

In H.264, computational complexity and memory access of deblocking filters are variable, dependent on video contents. This paper proposes a VLSI architecture of deblocking filters with adaptive dynamic power, which avoids redundant computations and memory accesses by precluding the blocks that can be skipped. The vertical and horizontal edges are simultaneously processed in an advanced scan order to speed up the decoder. As a result, dynamic power of the proposed architecture can be reduced adaptively （up to about 89%） for different videos, and the off-chip memory access is improved when compared to previous designs. Moreover, the processing capability of the proposed architecture is in particular appropriate for real-time deblocking of high-definition television （HDTV, 1920× 1080 pixels/frame, 60 frames/s video signals） video operation at 62 MHz. Using the proposed architecture, power can be reduced by up to about 89% and processing time by from 25% to 81% compared with previous designs.  相似文献

The role of effort in moderating the anxiety – performance relationship: Testing the prediction of processing efficiency theory in simulated rally driving

Abstract

We tested some of the key predictions of processing efficiency theory using a simulated rally driving task. Two groups of participants were classified as either dispositionally high or low anxious based on trait anxiety scores and trained on a simulated driving task. Participants then raced individually on two similar courses under counterbalanced experimental conditions designed to manipulate the level of anxiety experienced. The effort exerted on the driving tasks was assessed though self-report (RSME), psychophysiological measures (pupil dilation) and visual gaze data. Efficiency was measured in terms of efficiency of visual processing (search rate) and driving control (variability of wheel and accelerator pedal) indices. Driving performance was measured as the time taken to complete the course. As predicted, increased anxiety had a negative effect on processing efficiency as indexed by the self-report, pupillary response and variability of gaze data. Predicted differences due to dispositional levels of anxiety were also found in the driving control and effort data. Although both groups of drivers performed worse under the threatening condition, the performance of the high trait anxious individuals was affected to a greater extent by the anxiety manipulation than the performance of the low trait anxious drivers. The findings suggest that processing efficiency theory holds promise as a theoretical framework for examining the relationship between anxiety and performance in sport.  相似文献
