论美声唱法的"靠前"与"靠后"     

严露 《贵阳师范高等专科学校学报》2005,(3):71-73

美声唱法分为“靠前”与“靠后”两大学派。“靠前唱法”强调声音的明亮、靠前、打在硬口盖上．集中于面孔前部（鼻腔、面罩）部位；“靠后唱法”则强调声音的厚度、力度、喉腔开度大，音的立体柱状感及音的落点感受较深。它们有机结和点在于声音的明亮集中、圆润、丰满，两派是互补的辩证统一的。  相似文献

Purpose: The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. Methods: This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32–37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. Results: The number of sport disciplines participated in was inversely associated with WC, the linear decrease averaging 1.38?cm (95% CI 1.10–1.65) per each additional sport discipline. The result persisted after adjustment for the main covariates, such as volume of PA and diet quality. Among dizygotic twin pairs discordant for sports participation (0–2 vs. 5 or more disciplines), the mean within-pair difference in WC was 4.8?cm (95% CI 0.4–9.1) for men and 11.2?cm (95% CI 4.4–18.0) for women; among discordant monozygotic pairs, no differences were observed. In men, all three types of sports were individually associated with smaller WC, while in women, only mixed and power sports showed this association. Conclusions: Participation in several sport disciplines and sport types was associated with smaller WC among young adults in their mid-30s. Shared genetic background may explain some of the associations.  相似文献

任福禄 《江西师范大学学报(哲学社会科学版)》2005,38(4):35-37

在《晋书音义》的音系中，舌音中的舌头、舌上两组声母的分化情况是：端、知不分，仍为一个声母——端母，透、彻彻底分化，是两个声母；定、澄彻底分化，是两个声母；泥、娘不分，仍是一个声母——泥母。对于学术界有关这一问题的一些有代表性的不同说法，本文作了辨正。  相似文献   

Improving Writing Skills of Thai EFL Students by Recognition of and Compensation for Factors of L 1 to L2 Negative Transfer     

William J. Sersen 《美中教育评论》2011,(3):339-345

In this study, we examined the likelihood of a TAME （extended technology acceptance model）, in which the interrelationships among computer self-efficacy, perceived usefulness, intention to use and self-reported use of computer-mediated technology were tested. In addition, the gender- and age-invariant of its causal structure were evaluated. The data were collected from a self-reported questionnaire administered to 477 administrative staff of a public university in Malaysia. The results of structural equation modeling supported the adequacy of TAME. Although the TAME＇s causal structure was applicable to both male and female staff, age group appeared to moderate the structural relationships among the constructs of interest.  相似文献
