The research on the current situation and measures of oral communication teaching in vocational education

良好的口语交际能力是社会选用、聘用人才的一项重要条件。中等职业学校为社会培养实用技术型人才，注重学生实用能力的培养。但目前中等职业学校学生口语交际能力低下的状况难以适应日益密切的社会交往的需要，影响了学生正常的社会交往，制约了学生的发展未来，使他们错失了发展的良机。基于对口语交际重要性和中职学生口语交际能力低下的现实的充分认识，笔者试图在已有研究成果基础上，从中职口语交际教学现状分析入手，结合口语交际特点，对中职口语交际教学目标、训练模式、评价机制等方面的理论和实践成果做一番整理，结合职业学校的专业特点、把学生的专业能力培养与口语交际能力培养结合起来，形成切实有效的教学对策以指导实际教学。 ...Abstract In the changeable age of information, vocational education focuses on training the students’ practical skills and abilities, so that colloquial inter-communication abilities have been the direct way to show quality and the base of personal success.

Observation on Some Activities of Reproduction in Little Egrets (Egretta garzetta) at Jiyu Island in Xiamen

于 2 0 0 1年 3～ 7月采用颜色标记法 ,记录厦门白鹭保护区内鸡屿岛白鹭 (Egrettagarzetta)卵产出和孵出的顺序和时间 ,并称重卵和雏鸟。有 91 4 %的窝卵数为 4～ 5枚 ,产卵期 7 0± 1 9d ,出壳期 4 2± 1 4d ;卵孵化时间与产卵顺序显著负相关 ;不同产出顺序卵重无差异 ;不同孵出顺序雏鸟早期 (≤ 5d)发育无差异 ,之后差异显著 ,第 4出壳的雏鸟发育水平和成活率较低 ,而第 5出壳的雏鸟最低 ;亲鸟在产卵期的孵化是非连续的 ,而产卵结束后相对连续。如此 ,可以调节孵化时间 ,进而调控异步孵化的程度 ,使雏鸟在生长阶段形成适当的等级差别 ,以获得最大的繁殖收益。Data on breeding of Little egrets (Egretta garzetta) were collected in a period from March to July of 2001 at Jiyu Island in Xiamen Egret Natural Reserve.Eggs and nestlings were marked with colors for identifying the egg-laying and hatchling sequences.Ninety one percent of clutch sizes were 4 and 5,the laying period was 7.0±1.9?d,and hatching spread was 4.2±1.4?d;the incubation time was negatively correlated with the laid order of eggs;the mass was not different for the eggs laid early or late;at early stage of development (≤5?d),nestlings were not different in growth,but a significant difference appeared after then,the rate of growth and survival was the lowest for the 5th hatchling,and the second for the 4th when counting backwards.Incubation was not continuous in laying period,and became relatively continuous after that period.By this way,the parents may regulate the incubation time,and further adjust the asynchronism of incubation,resulting in a dominance hierarchy among the nestlings,which would maximize the reproductive success.福建省自然科学基金资助项目 (D9910 0 0 3 );; 厦门市环境保护科研所资助项

In this work, we used an electrochemically-gated, mechanically-controllable break junction technique to tune the electronic behaviour of thiophene-based molecular junctions that show destructive quantum interference (DQI) features. By varying the voltage applied to the electrochemical gate at room temperature, we reached a conductance minimum that provides direct evidence of charge transport controlled by an anti-resonance arising from DQI. Our molecular system enables conductance tuning close to two orders of magnitude within the non-faradaic potential region, which is significantly higher than that achieved with molecules not showing DQI. Our experimental results, interpreted using quantum transport theory, demonstrate that electrochemical gating is a promising strategy for obtaining improved in-situ control over the electrical performance of interference-based molecular devices.This research was supported by the National Key R&D Program of China (2017YFA0204902), National Natural Science Foundation of China (21722305, 21673195, 21503179, 21703188), the Program for Professor of Special Appointment (Eastern Scholar) at Shanghai Institutions of Higher Learning, Natural Science Foundation of Shanghai (17ZR1447100), Science and Technology Commission of Shanghai Municipality (14DZ2261000), China Postdoctoral Science Foundation (2017M622060) for funding work in Xiamen.
