历届NMET短文改错相似题浅析(续)     

郝昌明 《中学生英语读写(高考版)》2003,(4)

历届高考相似题考点七：表示时间的固定短语前不能随意加介词有些考生由于受汉语习惯的影响，喜欢在没有介词的表示时间的固定短语前加介词，造成表达错误。高考短文改错题很注重考查考生使用这些时间短语时是否受汉语习惯影响。NMET蒺02:IwassotiredthatIfellasleepatthemomentmyheadtouchedthepillow.析：themoment虽表示“在……时刻”，但在这里作连接词，前边不应加任何介词，所以应将at去掉。NMET蒺96:Infact,theyareplanningtovisitChinainnextyear.析：nextyear,thenextyear等时间短语在汉语里虽可说成“在下一年”，但英语表…  相似文献   

Use of laptop computers in an academic medical library     

Atlas MC  Garza F  Hinshaw R 《Medical reference services quarterly》2007,26(2):27-36

Who borrows laptop computers in an academic health sciences library? Why do they choose to check out laptops? In a survey, laptop computer users responded that the laptops were used most frequently to do class-related work. Laptops were most often checked out because they could be taken to a quiet area of the library or to where the user had more room to work. The majority of such borrowers were satisfied or very satisfied with the laptops and the service from the library. The majority of those completing the survey were medical school students and graduate students. The circulation of laptop computers at this academic health sciences library is a very successful and popular program.  相似文献   

A rapid and accurate 3-（4,5-dimethyl thiazol-2-yl）-2,5-diphenyl tetrazolium bromide colorimetric assay for quantification of bacteriocins with nisin as an example     

Wang F  Cao LT  Hu SH 《Journal of Zhejiang University. Science. B》2007,8(8):549-554

The objective of this study is to propose a more accurate and faster MTT 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide colorimetric assay (MCA) for quantitative measurement of polypeptide bacteriocins in solutions with nisin as an example. After an initial incubation of nisin and indicator bacterium Micrococcus luteus NCIB 8166 in tubes, MTT was added for another incubation period. After that, nisin was quantified by estimating the number of viable bacteria based on measuring the amount of purple formazan produced by cleavage of yellow tetrazolium salt MTT. Then MCA was compared to a standard agar diffusion assay (ADA). The results suggested a high correlation coefficient (r2=0.975±0.004) between optical density (OD) and the inhibitory effect of nisin on a bacterial strain Micrococcus luteus NCIB 8166 at a range of 0.125～32 IU/ml. The MCA described in this study was very quick. Quantification of nisin took only 7～8 h and the detection limit was at the level of 0.125 IU/ml when compared to 12 IU/ml and 24～28 h for ADA. The MCA provides an accurate and rapid method for quantifi-cation of nisin in solutions and is expected to be used for quantification of other antimicrobial substances.  相似文献   

Supplemental instruction in introductory biology I: enhancing the performance and retention of underrepresented minority students     

Rath KA  Peterfreund AR  Xenos SP  Bayliss F  Carnal N 《CBE life sciences education》2007,6(3):203-216

Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the Introductory Biology I class is associated with even more dramatic gains among students from underrepresented minority populations than the gains found among their peers. These gains do not seem to be the product of better students availing themselves of supplemental instruction or other outside factors. The Introductory Biology I class consists of a team-taught lecture component, taught in a large lecture classroom, and a laboratory component where students participate in smaller lab sections. Students are expected to master an understanding of basic concepts, content, and vocabulary in biology as well as gain laboratory investigation skills and experience applying scientific methodology. In this context, supplemental instruction classes are cooperative learning environments where students participate in learning activities that complement the course material, focusing on student misconceptions and difficulties, construction of a scaffolded knowledge base, applications involving problem solving, and articulation of constructs with peers.  相似文献   

具身传播、参与式互动、场景社交：数字交互式电影的新考察     

郭昌明  黄献文 《新闻爱好者》2023,(2):97-100

数字交互式电影的出现创造了电影史上的一次重大革命,它不仅在电影表现手法、叙述策略上重构电影的叙事维度,而且从本质上改变了电影观众的定义,促使电影受众由单一意义的观众转变为具有多重意义的用户。一方面,数字交互式电影为受众带来了“身体在场”的沉浸式观影体验,电影的媒介功能被进一步延伸;另一方面,“用户”的出现也揭示电影受众不再仅作为电影被动的观看者,而是能够以介入的姿态更积极地参与电影的呈现与制作过程,受众成为电影本身不可割裂的一部分。同时,数字交互式电影以其本身的交互性特点,完成了“基于社交的电影”到“基于电影的社交”的全新转换,构建了基于电影空间的网络社交新场景,这种特定的场景社交进一步提升了电影的传播效果,带给受众全新的观影感受。  相似文献

歙县北乡话方言本字考   总被引：2，自引：0，他引：2  

沈昌明 《黄山学院学报》2011,13(6):14-18

歙北方言隶属于徽语区,对其本字考证对于徽语其它方言点具有很强的借鉴意义。为了解决方言调查中,特别是整理方言同音字表时出现的有音无字的这一问题,通过参考有关工具书,主要是《广韵》、《集韵》以及其它方言的本字考证释例,并对已经考证的本字进行分析,可以找到古今语音的对应变化规律。还可以佐证文字发展的总体趋势——简化的必要性。  相似文献
