The lexical approach can help students learn to use English in an idiomatic way rather than in a Chinese way which may cause misunderstanding or confusion of native English speakers. As for the college English Teaching in China, the lexical approach works better than the traditional word-based teaching and learning. It can help students to learn ＂real＂ or ＂authentic＂ English and improve the students＇ ability to use English in all-around way.展开更多

No report has existed so far on the study of the effects of exogenous chromosomes on photosynthesis using the substitution series as materials. In this research, Triticum aestivum cv. Chinese Spring-Lophopyrum elongatum （Host） A.Loeve disomic substitution series were used as materials and flag leaves as the measuring position. And the CI-310 Portable Photosynthesis System made by CID Co. in USA was used to measure the net rate of photosynthesis of flag leaves in different developing stages and also to correlate photosynthesis with yield. Results showed that, out of the whole developing stages, at the anthesis stage the line of DS2Ee （2A） had the highest photosynthetic rate, therefore it could be used in improving process of the character of kernel number. The flag leaves of DS4Ee （4A, 4B, 4D） lines demonstrated certain high net photosynthetic rate from heading to grain filling stage, so it is valuable in the researh of promoting the yield index like 1 000-grain weight through improvement of the photosynthetic rate at grain filling stage.展开更多

The results show that left-handedness with zero absorption is achieved. The zero absorption property displays the possibility of manipulation by varying the phase and the intensity of the coupling field. Also, the zero absorption property may be used to amplify the evanescent waves that have been lost in imaging by traditional lenses. We propose an approach to obtain a negative refractive medium with zero absorption and the possibility of enhaneeingthe imaging resolution in realizing ＇superlenses＇.展开更多

The essay thus is carried out around the major linguistic aspects--phonetics, formation of words and syntax to detect the applicability of Cassirer＇s theory to the early development of Chinese.展开更多

Two equal and tunable peaks in the 2D plane are obtained by the detunings corresponding to the two orthogonal standing-wave fields when the decreasing intensities of spontaneously generated coherence (SGC) arise in the three-level Λ-type atomic system, while one circular ring with shrinking radii in the 2D plane is obtained by the adjusted phases and wave vectors of the standing-wave fields when the increasing intensities of SGC occur in the three-level Λ-type atomic system. 2D atom localization with the single ring with shrinking radii realized by the multiple parametric manipulations demonstrated the flexibility for our scheme.展开更多

In the gain process, two equal and tunable peak maxima of position distribution in the – plane via the detunings are observed. However, one decreasing and the other increasing peak maxima in the absorption process via the SGC are achieved in the quadrants I and III of the x–y plane. A better resolution and more novelty for the 2D atom localization in our scheme are obtained.展开更多
文摘This paper discusses the lexical approach in college English teaching and learning. The lexical approach can help students learn to use English in an idiomatic way rather than in a Chinese way which may cause misunderstanding or confusion of native English speakers. As for the college English Teaching in China, the lexical approach works better than the traditional word-based teaching and learning. It can help students to learn ＂real＂ or ＂authentic＂ English and improve the students＇ ability to use English in all-around way.
