在职业中学普通话教学中,除了让学生掌握发音技巧,还不能忽略正音能力的培训。正音能力的培训包括正音意识的强化、正音技能的具备和正音方法的掌握三方面,虽然正音意识的强化过程会影响会话速度但却很有必要,正音技能包括对语音的敏感能力、对语音的听辨能力和对语音学习坚持不懈的毅力,正音方法通过多练习、多记录、多背诵才能掌握。 相似文献

一 汉语教学（一）正音工作：在全册的十四个练习课中,都注意了正音工作。在整个正音工作中都没有离开注音字母,这不仅使儿童能熟练地认和写注音字母,而且可培养他们独立地进行双拼音和三拼音的练习。在练习课中还采取了如下的几种方法进行正音： 相似文献

《全日制汉语国际教育硕士专业学位外国留学生指导性培养方案》中并未设置正音课,但是基于汉语国际教育硕士专业学位留学生的发音现状,文章认为有必要开设＂汉语正音课＂作为选修课,以帮助留学生纠正发音并提高他们汉语表达的标准度与准确度。文章以教学实践为基础,对＂汉语正音课＂提出了具体的教学设计,同时结合教学评估做出了一些思考。 相似文献

<马氏等音>是清初云南学者马自援所作的一部韵图.马自援出生于云南,长期的生活环境主要是驻扎云南的部队,所处的语言大环境相对比较复杂,马自援写<马氏等音>的目的,主要是为了读书"正音"."正音"只是一个理想中的概念,因地而异、因人而异,但正音与具有通语性质的"官话"有着密切的关系. 相似文献

虽然对维吾尔语口语中不同方言词中的语音脱落,换位,弱化等语言现象制定了一定的正音正字形式,但还是存在一些待解决的问题。语流音变中脱落音“r”的正音正字形式的不规范性就是其中的显著问题之一。本文主要论述该问题。 相似文献

R·E·帕尔默 《安徽师范大学学报(人文社会科学版)》2002,30(5):502-508
"存在之显现" 是伽达默尔的真理观念."时间性"指的是通过语言性、书写性、和诗歌的奇迹,产生了文本战胜历史"时间"而具有"同时性" 的奇迹."实践智慧" 是伦理方式选择善的理智."应用"的意思是当我们理解过去的某件事物时,我们同样领会它在今天是如何应用的 "传统"是指我们在语言中继承下来的态度和方法,在我们试图弄懂任何事物时都会在我们的意识中发生作用,而"效果历史意识" 是一种历史总结在发挥作用的意识.语言最典型地生存于交谈、问答、对话的平等交换之中.使人类团结在一起的的节日庆典是真正交流的基础. 相似文献

The effects of the concentration of dissolved total organic carbon(TOC),the TOC/Br-ratio,bromide ion levels,the chlorine to ammonia-N ratio(Cl:N),the monochloramine dose and the chlorine dose on the formation of trihalomethanes(THMs)(including chloroform,bromodichloromethane,chlorodibromomethane,and bromoform)from chlorination were investigated using aqueous humic acid(HA)solutions.The profile of the chloramine decay was also studied under various bromide ion concentrations.Monochloramine decayed in the presence of organic material and bromide ions.The percentage of chloroform and brominated THMs varied according to the TOC/Br-ratio.Total THMs(TTHMs)formation increased from 112 to 190 μg/L with the increase concentrations of bromide ions from 0.67 to 6.72 mg/L,but the chlorine-substituted THMs were replaced by bromine-substituted THMs.A strong linear correlation was obtained between the monochloramine dose and the formation of THMs for Cl:N ratios of 3:1 and 5:1.These ratios had a distinct effect on the formation of chloroform but had little impact on the formation of bromodichloromethane or chlorodibromomethane.The presence of bromide ions increased the rate of monochloramine decay. 相似文献

The cross-lagged panel model (CLPM), a discrete-time (DT) SEM model, is frequently used to gather evidence for (reciprocal) Granger-causal relationships when lacking an experimental design. However, it is well known that CLPMs can lead to different parameter estimates depending on the time-interval of observation. Consequently, this can lead to researchers drawing conflicting conclusions regarding the sign and/or dominance of relationships. Multiple authors have suggested the use of continuous-time models to address this issue.
In this article, we demonstrate the exact circumstances under which such conflicting conclusions occur. Specifically, we show that such conflicts are only avoided in general in the case of bivariate, stable, nonoscillating, first-order systems, when comparing models with uniform time-intervals between observations. In addition, we provide a range of tools, proofs, and guidelines regarding the comparison of discrete- and continuous-time parameter estimates. 相似文献

Midpalatal corticotomy-assisted rapid maxillary expansion(MCRME)is a minimally invasive treatment of maxillary transverse deficiency(MTD)in young adults.However,the effect of MCRME on respiratory function still needs to be determined.In this study,we evaluated the changes in maxillary morphology and the upper airway following MCRME using computational fluid dynamics(CFD).Twenty patients with MTD(8 males,12 females;mean age 20.55 years)had cone-beam computed tomography(CBCT)images taken before and after MCRME.The CBCT data were used to construct a threedimensional(3 D)upper airway model.The upper airway flow characteristics were simulated using CFD,and measurements were made based on the CBCT images and CFD.The results showed that the widths of the palatal bone and nasal cavity,and the intermolar width were increased significantly after MCRME.The volume of the nasal cavity and nasopharynx increased significantly,while there were no obvious changes in the volumes of the oropharynx and hypopharynx.CFD simulation of the upper airway showed that the pressure drop and maximum velocity of the upper airway decreased significantly after treatment.Our results suggest that in these young adults with MTD,increasing the maxillary width,upper airway volume,and quantity of airflow by MCRME substantially improved upper airway ventilation. 相似文献

Smart classroom (SC) is an important embodiment of the new teaching mode in online and offline integration in the COVID-19. At present, the research on the evaluation system of teacher-student interaction (TSI) in SC lacks evaluation system to guide the development of students’ higher order thinking (HOT). This evaluation system of TSI was established through grounded theory, Delphi method and analytic hierarchy process. The evaluation system for TSI considered the support of intelligent technology for various indicators and the development of students’ HOT. The evaluation system included 4 first level indicators, 16 s level indicators and 44 third level indicators. The evaluation system had been comprehensively evaluated the TSI activities, which was conducive to the development of students’ HOT.Data availabilityData used in this research are available upon request from the corresponding author. 相似文献

Postherpetic neuralgia (PHN) is a severe sequela of herpes zoster (HZ). Until now, only age and pain severity were considered
predisposing factors for the development of PHN. We evaluated 49 patients with acute phase HZ, 10 of whom developed PHN (Group
A) and 39 of whom did not develop PHN (Group B). Twenty-five healthy volunteers similar in age and gender distribution to
the study group were recruited as controls (Group C). Numbers of serum CD3+ (pan-T lymphocytes), CD4+ (helper/inducer), and CD8+ (suppressor/cytotoxic) lymphocytes were decreased significantly in Groups A and B relative to the control group, but there
were no statistical differences between Groups A and B. Interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, IL-8, and
IL-10 were significantly elevated in Groups A and B relative to Group C. IL-6 was significantly higher in Group A than in
Group B, and was significantly positively correlated with pain severity scored on a visual analog scale. Therefore, we suggest
that the inflammatory response, especially that of IL-6, in the acute phase of HZ may be associated with hyperalgesia and
the development of PHN.
