Two aspects are shown in this paper： communication between people of different social status, genders and casual relationships, and communication between people of same social status, genders and close relationships. Therefore, the study result can be concluded like this： whether the use of indirect speech act is successful or not always influences people＇s communication significantly.展开更多

The regions in pairs associated to form a feature were not necessarily directly-connected, but were selected dedicatedly to the grey transition between regions coinciding with the face pattern structure. Fifteen brighter and darker region pairs were chosen to form the region pair grey difference features with high discriminant capabilities. Instead of using both false acceptance rate and false rejection rate, the mutual information was used as a unified metric for evaluating the classifying performance. The parameters of specified positions, areas and grey difference bias for each single region pair feature were selected by an optimization processing aiming at maximizing the mutual information between the region pair feature and classifying distribution, respectively. An additional region-based feature depicting the correlation between global region grey intensity patterns was also proposed. Compared with the result of Viola-like approach using over 2 000 features, the proposed approach can achieve similar error rates with only 16 features and 1/6 implementation time on controlled illumination images.展开更多

The results indicate that the autonomous listening ability for college students is at the medium level with a great individual difference and there＇s a vast space to be promoted. Moreover, there＇s no significant gender difference in autonomous listening ability for college students and there＇s significant positive correlation between autonomous listening ability and CET-4 Listening achievement, especially the dimension of Application of Strategies. Thus, a conclusion can be drawn that in English listening teaching, teachers should change their teaching model and strengthen the application of network teaching; in English listening learning, English learners should promote their ability of using strategies in English listening in order to improve their autonomous learning ability.展开更多
文摘The paper tentatively studies the function of the indirect speech act in Chinese cultural communication, namely, domestic communication. Two aspects are shown in this paper： communication between people of different social status, genders and casual relationships, and communication between people of same social status, genders and close relationships. Therefore, the study result can be concluded like this： whether the use of indirect speech act is successful or not always influences people＇s communication significantly.
