A relatively large genetic diversity was detected among the samples based on estimation of DNA products amplified from 15 selected ISSR primers, with the similarity coefficient varying from 0.17 to 0.89. The mean expected heterozygosity (He) was 0.171 4 per locus, and Shannon index (1) was 0.271 4. The Principal Coordinate Analysis (PCA) further indicated that genetic diversity of the Jiangwan wild soybean population was not evenly distributed, instead, was presented by a mosaic or clustered distribution pattern. Correlation study between genetic diversity and number of samples demonstrated that genetic diversity increased dramatically with the increase of number of samples within 40 individuals, but the increase became slow and rapidly reached a plateau when more than 40 individuals were included in the analysis. It is concluded that (i) a sample set of approximately 35-45 individuals should be included to represent possibly high genetic diversity when conservation of a wild soybean population ex situ is undertaken; and (ii) collection of wild soybean samples should be spread out as wide as possible within a population, and a certain distance should be kept as intervals among individuals for sampling.展开更多

The results show that, during L2 vocabulary teaching process, the proper application of interlingual strategies can effectively facilitate the memorization of new words, and the bilingual method （both English explanation and Chinese translation） is welcomed by most subjects. Therefore, using L1 as a means of semantization or as a tool for checking and validating L2 learners＇ understanding of word meaning should not be completely rejected, especially for adult Chinese EFL learners.展开更多

This paper investigates the characteristics of the notes taken by student interpreters in relation to the output and the process of interpretation with the purpsoe of identifying the role of note-taking in the process of interpretation, its relations with the production quality, and the factors that constrain the development of the students＇ potential as future interpreters. Statistical and qualitative analysis of the notes and think-aloud protocol reveals that students majoring in English should further improve their overall English proficiency. Note-taking, either in source language or target language, or both, should be practiced until students are able to use it expertly. Inspite of the importance of note-taking in interpretation, students should be trained to rely more on memory rather than solely on the notes.展开更多
