Hip-hop is popular among Chinese teenagers is not only due to the young people＇s psychological needs, but also because of the profound connotation of the era. Hip hop can contribute to the campus cultural construction. However, it also implies that local youth culture is missing in China. Hip hop dance was born in 1960s and classified into hip hop culture in 1970s as a typical representative of the four Hip-hop elements together with Graffiti, DJing, and MCing. It was spread into China in 1980s together with the movie Breakin： Hip hop has gradually become popular with Guangzhou, Shanghai, and Beijing as the center drawing much attention of the Chinese youth. Its educational significance cannot ignored from the perspective of youth culture, reflecting the absorption, digestion and development of foreign culture among Chinese young people,At the same time, it provides a good platform for young people to show their unique personality, passion, courage and life attitude.展开更多

The reason the author believes dual language programs could benefit all is due to the fact that if done properly, it should promote bilingualism, respect, and equity for all students in the school. Dual language programs are relatively new in the United States. These programs aim to create bilingual, bicultural students without sacrificing these students＇ success in school or beyond. The goals of dual language are to provide high-quality instruction for language-minority students and to provide instruction in a second language for English-speaking students. Schools teach children through content, with teachers adapting their instruction to ensure children＇s comprehension and using content lessons to convey vocabulary and language structure. Striving for a balance of half language minority students and half English speaking students in each classroom, dual language programs also aim to teach cross-cultural awareness. Programs vary in terms of the amount of time they devote to each language, which grade levels they serve, how much structure they impose for the division of language and curriculum, and what populations they serve.展开更多

Oromandibular morphology within the Labeoninae is the greatest among cyprinid fishes. Although several phylogenetic studies about labeonines have been undertaken the results have been inconsistent and a comprehensive phylogeny is needed. Further, an incongruence between morphological and molecular phylogeny requires a systematic exploration of the significance of morphological characters on the basis of the molecular phylogeny. In this study, a total of 292 nucleotide sequences from 73 individuals （representing 24 genera and 73 species） of Labeoninae were analyzed. The results of the phylogenetic analysis indicate that there are four major clades within Labeoninae and three monophyletic lineages within the fourth clade. Results of the character evolution show that all oromandibular morphological characters are homoplastically distributed on the molecular phylogenetic tree and suggests that these characters evolved several times during the history of labeonines. In particular, the labeonine, a specific disc on the lower lip, has been acquired three times and reversed twice. These morphological characters do not have systematic significance but can be useful for taxonomy. The results of biogeography suggest that the Labeoninae originated from Southeast Asia and separately dispersed to Africa, East Asia and South Asia.展开更多
