However, at present, there are few studies on the "contemporary cultural participation task group" in the field of Chinese education research. This paper expounds the teaching practice strategy of "contemporary culture participation task group" from three perspectives of "creating the situation, showing the contemporary real life", "based on words, excavating the hidden language flavor" and "studying the contemporary cultural phenomenon based on culture". The learning task group provides a good background for language transmission, which can stimulate students enthusiasm for language decoding and language coding, make students willing to invest in Chinese learning, and effectively experience the application of Chinese learning, so that the pragmatic into practice.展开更多

Based on the requirements of the new curriculum reform, the concept of learning task group arises at the historic moment and is organically integrated with high school Chinese teaching, which plays a very important role in promoting the optimization of high school Chinese teaching contents and methods. In this paper, based on the "learning task group" of high school Chinese multi-text reading teaching to conduct an in-depth exploration, combined with the current development of high school Chinese multi-text reading teaching, put forward scientific and reasonable suggestions, in order to improve our country's high school Chinese education level, promote the modernization of our country's education to further develop, provide more reliable reference.展开更多

Fault tolerance with active replication and load balancing techniques are used. The pros and cons of both techniques are analyzed, and a novel load balancing framework for fault tolerant systems with active replication is presented. Hierarchical architecture is described in detail. The framework can dynamically adjust fault tolerant groups and their memberships with respect to system loads. Three potential task scheduler group selection methods are proposed and simulation tests are made. Further analysis of test data is done and helpful observations for system design are also pointed out, including effects of task arrival intensity and task set size, relationship between total task execution time and single task execution time.展开更多
