非范畴化是指为在一定的条件下,范畴成员逐渐失去范畴特征的过程。这些成分在重新范畴化之前处于一种不稳定的中间状态,它们丧失了原有范畴的某些典型特征,同时获得了新范畴的某些特征。以非范畴化理论为依据,探讨日语复合动词的构成要素在非范畴化阶段的副词化现象。从意义上看,复合动词副词化的构成要素在副词化过程中丧失了原意,获得了加强主要动词动作的程度副词意;从句法特征上看,副词化的构成要素丧失格支配能力。  相似文献

Enhancing motivation in adult learners is often a difficult task in today’s college classroom. Significant reforms in America’s educational system have directed the initiative to adopt Common Core Standards in Language Arts by all 50 states. With the focus on increased rigor and depth of understanding in learning, the hope is to prepare students throughout the K–12 sequence for college and careers. This new instructional model requires moving students from passive recipients to active learners. Although the arrival of an expanding population is encouraging for college communities, the issue of underprepared college students must be addressed. Instructional methods designed to cultivate active learning and critical thinking through more contextualized, hands-on teaching activities produced initial evidence of improved reading achievement.  相似文献

基于Mann-Kendall法的酒泉市近50年气候变化特征及突变分析   总被引:2,自引:0,他引:2  
利用酒泉市所属6个站点1959-2008年的气温和降水资料,采用滑动平均、趋势分析和MannKendall等方法,分析该地区的气候变化的特征.结果表明:在全球变暖背景下,酒泉市的气温突变明显,而降水突变不明显.近50年来,酒泉市年平均气温和各个季节的平均气温呈显著变暖趋势,其中年平均气温在90年代中后期发生了突变,酒泉市东部的突变年份早于西部的突变年份;酒泉市年降水量呈微弱增长趋势,酒泉市东部的增长幅度略小于西部.这表明气候突变在酒泉市不同的地区会有不同的体现,突变时间不同步.  相似文献

The written English vocabulary of 72 deaf elementary school students of various proficiency levels in American Sign Language (ASL) was compared with the performance of 60 hearing English-as-a-second-language (ESL) speakers and 61 hearing monolingual speakers of English, all of similar age. Students were asked to retell "The Tortoise and the Hare" story (previously viewed on video) in a writing activity. Writing samples were later scored for total number of words, use of words known to be highly frequent in children's writing, redundancy in writing, and use of English function words. All deaf writers showed significantly lower use of function words as compared to their hearing peers. Low-ASL-proficient students demonstrated a highly formulaic writing style, drawing mostly on high-frequency words and repetitive use of a limited range of function words. The moderate- and high-ASL-proficient deaf students' writing was not formulaic and incorporated novel, low-frequency vocabulary to communicate their thoughts. The moderate- and high-ASL students' performance revealed a departure from findings one might expect based on previous studies with deaf writers and their vocabulary use. The writing of the deaf writers also differed from the writing of hearing ESL speakers. Implications for deaf education and literacy instruction are discussed, with special attention to the fact that ASL-proficient, deaf second-language learners of English may be approaching English vocabulary acquisition in ways that are different from hearing ESL learners.  相似文献

To examine the influence of pre-warming on the physiological responses to prolonged intermittent exercise in ambient temperatures of 21.5?±?0.6°C and relative humidities of 35.7?±?5.4% (mean?±?s), six healthy men performed intermittent treadmill running (30-s bouts at 90% of maximal oxygen uptake separated by 30-s static recovery periods) to exhaustion after active pre-warming, passive pre-warming and pre-exercise rest (control). Exercise time to exhaustion was significantly different between all conditions (active, 51.8?±?7.2?min; passive, 38.5?±?11.1?min; control, 72.0?±?17.2?min; P <?0.05). These changes in performance time were closely associated with a significant decline in both the rate of heat storage and heat storage capacity (P <?0.05). Rectal temperature, heart rate and ratings of perceived exertion were significantly higher during exercise in the two pre-warming conditions than in the control condition (P <?0.05). Ratings of perceived exertion were also significantly higher during exercise following passive pre-warming compared with active pre-warming (P <?0.05). During exercise there were no significant differences in serum prolactin, plasma norepinephrine and plasma free fatty acid concentrations between conditions. We conclude that both active and passive pre-warming promote a reduction in prolonged intermittent exercise capacity in environmental temperatures of 21°C compared with pre-exercise rest. These performance decrements were dependent upon the mode of pre-warming and closely reflected alterations in body heat content.  相似文献

Abstract

In this study, we examined the correlations between selected markers of isometric training intensity and subsequent reductions in resting blood pressure. Thirteen participants performed a discontinuous incremental isometric exercise test to volitional exhaustion at which point mean torque for the final 2-min stage (2min-torquepeak) and peak heart rate peak (HRpeak) were identified. Also, during 4 weeks of training (3 sessions per week, comprising 4 × 2 min bilateral leg isometric exercise at 95% HRpeak), heart rate (HRtrain), torque (Torquetrain), and changes in EMG amplitude (ΔEMGamp) and frequency (ΔEMGfreq) were determined. The markers of training intensity were: Torquetrain relative to the 2min-torquepeak (%2min-torquepeak), EMG relative to EMGpeak (%EMGpeak), HRtrain ΔEMGamp, ΔEMGfreq, and %MVC. Mean systolic (?4.9 mmHg) and arterial blood pressure (?2.7mmHg) reductions correlated with %2min-torquepeak (r = ?0.65, P = 0.02 and r = ?0.59, P = 0.03), ΔEMGamp (r = 0.66, P = 0.01 and r = 0.59, P = 0.03), ΔEMGfreq (r = ?0.67, P = 0.01 and r = ?0.64, P = 0.02), and %EMGpeak (systolic blood pressure only; r = ?0.63, P = 0.02). These markers best reflect the association between isometric training intensity and reduction in resting blood pressure observed after bilateral leg isometric exercise training.  相似文献

This investigation provides an extensive review of scientific, religious, and otherwise non-scientific factors that may influence student acceptance of biological evolution. We also measure the extent to which students' levels of acceptance changed following an educational experience designed to address an inclusive inventory of factors identified as potentially affecting student acceptance of evolution (n = 81, pre-test/post-test) n = 37, one-year longitudinal). Acceptance of evolution was measured using the Measure of Acceptance of the Theory of Evolution (MATE) instrument among participants enrolled in a secondary-level academic programme during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than initial levels both immediately following and over one year after the educational experience. Results reported herein carry implications for future quantitative and qualitative research as well as for cross-disciplinary instruction plans related to evolutionary science and non-scientific factors which may influence student understanding of evolution.  相似文献
