With the emergence of the Cultural School in the 1990s, researchers began to deem that translation is inevitably associated with political tendencies and aspirations of social groups, and the relationship between source language and target language has never gone beyond politics and are always entangled with power. From political perspective, this thesis will take the popularity of Yu Hua’s works in US into account to analyze and explore how cultural soft power, has impacts on translation activities, especially translation direction and source text selection. 展开更多

In the past 30 years, code-switching has been a focus in the field of linguistics in western countries. Researchers stud?ied it from different angles and have made a lot of findings.However, the researchers in China begin their studies on this issue un?til the last decade. Thus,the relevent empirical studies were less and most of them only use students from the classrooms in the sec?ondary schools or the undergraduates in the universities as the subjects.They paid little attention to the EFL classrooms in the vo?cational colleges. Vocational college students are poor in English foundation. English teachers can not finish their teaching mission in English classroom, so the use of code-switching becomes a very common phenomenon in EFL class of vocational college. In order to make teaching and learning promote and enhance each other, according to previous research findings, this paper do a fur?ther study about the teachers' use of code switching in the vocational college English intensive reading classes in China. 展开更多

Figs (Moracea: Ficus) and fig wasps (Hymenoptera: Chlocloids: Agaonideae) depend on each other to complete their reproduction. Monoecious fig species and their pollinating wasps are in conflict over the use of fig ovaries which can either produce one seed or one wasp. From observation on Ficus virens Ait., we showed that female flowers with outer layer of ovaries (near to the wall of syconium) had no significant difference from that with inner and interval layer of ovaries (near to the syconium cavity), in which most seeds and wasps were produced. This meant that fig tree provided the same potential resource for seed and wasps production. Observation indicated that there was usually only one foundress in syconium at female flower phase and no com- petition pollinators. Measurement of the style length of female flowers and the ovipositor of pollinators indicated that most ovaries could be reached by pollinator’s ovipositor. However, at the male flower phase, production of seeds was significantly more than that of wasps including non-pollinating wasps but there was no significant difference between seed and pollinating wasp production when without non-pollinating wasps produced. This result indicated that non-pollinating wasps competed ovaries not with seeds but with pollinating wasps for ovipositing. Bagged experiment showed that the sampling fig species was not self-sterile which was important for figs and wasps to survive bad season. Seed production in self-pollinated figs was not significantly different from total wasps in- cluding non-pollinating ones. This might be related with the weaker competition among wasps since bagged figs were not easy to reach by wasps from outside. 展开更多
