预设触发语是句子中与预设义有语义联系的词语,通过触发语的词义,我们可以作常识性推理或者回溯推理,推导出句子的预设义。英、汉语中均有词汇作为预设触发语项,本文对英、汉语中词汇预设触发语的不同类型进行详尽描写,对比研究其异同,找出其语义特征,并能够依据这套特殊规则推理出它所引发的预设义。  相似文献

The aim of the reported eye-tracking study was to investigate whether learners integrate information presented on several pages within a digital learning environment and whether the underlying processes differ between a purely text-based and a multi-modal digital learning environment. Participants (N = 97) learned about the development of tornados. Picture presentation (yes vs. no) and presentation of inconsistent information between pages (yes vs. no) was varied between-subjects. Results showed that inconsistent information led to more intense gaze behavior. This indicates that learners re-activated information presented on previous pages to integrate it with the actual information, enabling them to detect the inconsistencies. Furthermore, the data pattern for text-related gaze behavior was not influenced by picture presentation, indicating that cognitive processes in purely text based or multi-modal learning environments are much the same. Comprehension outcomes did not differ between groups. The implications of these results are discussed.  相似文献

BackgroundThe main study objective was to investigate modern health worries (MHW) in a group of Pakistani immigrant women in Norway, and to compare it with a group of ethnic Norwegian women. A further aim was to examine differences in MHW with level of education and acculturation in this immigrant group.MethodsThe Pakistani women (N = 101) completed a questionnaire to assess MHW and sociodemographic variables. MHW data were obtained via telephone interviews for the subsample of Norwegian women (N = 344).ResultsThe Pakistani women generally showed lower levels of MHW than did the ethnic Norwegian women. However, when stratified on education, the difference was mainly apparent in the low and middle educational groups. The Pakistani women with high levels of education tended to report higher levels of MHW than those with lower education levels. They reported significantly higher levels of worries about avian flu, radiation from computer screens, and vaccination programmes than did the ethnic Norwegian women on the same high educational level. Their different degrees of acculturation in the Norwegian society appeared to influence their levels of MHW, as the assimilated women showed the highest levels of MHW, whereas the separated women showed the lowest levels.ConclusionsThe group of Pakistani immigrant women was very heterogeneous in terms of MHW, and health authorities and health care workers should therefor adapt health and risk information according to different levels of integration and education.  相似文献

句式的使用意图,都必须联系上下文语境去考察。“使”字句存在着条件、因果、目的和假设等多种不同的语义关系类型。各种不同语义关系的“使”字句的具体内容都能满足说话人不同的使用需求。使用条件关系的“使”字句,在意图上具有明显的一致性,使用目的和假设关系的“使”字句,有两种意图:有的是以句式的内容得出结论,有的则是把句式内容当作一种理由;而使用因果关系和可然(做法和作用)的“使”字句,其目的则是以句式本身的内容作为得出某种结论的理由或论据。  相似文献

Despite the egalitarianism that informs French civic culture, the socio-economic marginalization of citizens of non-European origin, mostly from North African countries, provide empirical evidence that challenges the French Republican ideal of integration. Such marginalization needs to be reconciled especially within the cultural realm. In this article, we look at French newspapers’ coverage of the children of immigrants during a ten-year period (2003–2013). We analyse coverage in three major newspapers since French news coverage can be considered to follow a specific political/literary model, which has a profound influence on how news in France is both coded and decoded. The article examines the ways political allegiances affect the portrayals of the children of immigrants. Using the constant comparative method, an analysis of the discourse over time shows that the narratives of integration of the decedents of North African immigrants have been complicated by the 2005 riots, both as a romantic illusion, a reflection of reality, or a possible outcome of events. The three newspapers grapple with the ambiguous position of the children of immigrants in French society in different ways. Coverage of children of immigrants continues to be divided along partisan lines which are bounded by the political/literary model of journalism. What is also clear is that the changing portrayal of children of immigrants is intrinsically attached to evolving social, political, and economic dynamics both nationally and beyond state borders.  相似文献
