The primary goal of Chinese agricultural development is to guarantee national food security and supply of major agricultural products. Hence, the scientiifc work on agricultural monitoring and early warning as wel as agricultural outlook must be strengthened. In this study, we develop the China Agricultural Monitoring and Early-warning System (CAMES) on the basis of a comparative study of domestic and international agricultural outlook models. The system is a dynamic and multi-market partial equilibrium model that integrates biological mechanisms with economic mechanisms. This system, which includes 11 categories of 953 kinds of agricultural products, could dynamical y project agricultural market supply and demand, assess food security, and conduct scenario analysis at different spatial levels, time scale levels, and macro-micro levels. Based on the CAMES, the production, consumption, and trade of the major agricultural products in China over the next decade are projected. The fol owing conclusions are drawn:i) The production of major agricultural products wil continue to grow steadily, mainly because of the increase in yield. i ) The growth of agricultural consumption wil be slightly higher than that of agricultural production. Meanwhile, a high self-sufifciency rate is expected for cereals such as rice, wheat, and maize, with the rate being stable at around 97%. i i) Agricultural trade wil continue to thrive. The growth of soybean and milk im-ports wil slow down, but the growth of traditional agricultural exports such as vegetables and fruits is expected to continue. 展开更多

Fiona and Marian,the two female roles of Alice Munro’s short story“The Bear Came Over the Mountain”always catch little attention of the readers who instead pay more attention to the male protagonist Grant.In actuality,the two female roles share a common point which needs readers and critics to carefully analyze and re-evaluate.That is both female roles’self-voice which is constrained against the man-center traditional perspective.This essay just aims to reanalyze and elaborate the two female roles by using the methods and theories of feminist criticism in order to discover and release the constrained self-voice of the female. 展开更多

This study examines strategies in responding to thanks by CanE (Canadian English) and CamE (Cameroon English) speakers. Based on data collected by means of a DCT (Discourse Completion Task) questionnaire, the study addresses formal, functional, situational, and interactional similarities and differences in both varieties of English. With regard to speaker strategies (Aijmer, 1996) or conventions of means, it was found that the Canadian participants mostly prefer "minimizing the favor" when responding to thanks, while the Cameroonians most frequently "express appreciation". At the level of the realization types, the findings show that patterns with "no problem" are predominant in the Canadian corpus, whereas the Cameroonian respondents rather employ patterns with "welcome". Differences can also be found in the situational distribution of the speaker strategies and their linguistic realizations as well as in the use and the length of supportive moves. 展开更多
