Consequently, it has become an important task for English teachers to think about how to develop students' language abilities for real communication. Nowadays, Communicative Language Teaching(CLT) has become a very popular teaching approach in China. CLT pays a lot attention to the social and functional elements in language daily use.展开更多

As a rural high school, our school has developed a comprehensive practical activity curriculum with the help of student associations. The introductory course enables students to understand what a comprehensive practical activity course is. It enables students to feel the comprehensive practical activity course type through the lesson of "electric bicycles are banned or standardized management". It also organizes students to carry out research study and carry out small topic research for students through the lesson of "energy conservation is at my side"—a topic selection and guidance course for comprehensive practical activities. In the activities, students' abilities of cooperation, communication, discussion and research are cultivated and improved.展开更多

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

In current college English teaching, it exists module, single and dogmatic and a series of disadvantage trends, taking comprehensive practice activities as the carrier to improve college English teaching efficiency, which has a multiplier effect. This paper first analyzes the importance of comprehensive practical activities in college English teaching activities, and then it proposes a set of practicable activity strategies, hoping to play a valuable role.展开更多

The so-called pre-listening stage is to guide students to prepare for listening before they officially start listening training, which can be simply understood as the upgraded version of pre-class preview activities;The listening stage naturally refers to the state in which the students focus on listening in the teaching form designed by the teachers in advance. This stage is mainly to help the students understand the general meaning of the listening materials and thus control the content they hear. As for the post-listening stage, it can be simply understood as more targeted after-class exercises. In this process, teachers need to combine the previous two stages to make corresponding post-listening activity teaching plan to help students better review and consolidate their knowledge.展开更多

However, the relationship between activated regions and motor recovery after mental practice training is not well understood. In this study, 15 patients who suffered a firstever subcortical stroke with neurological deficits affecting the right hand, but no significant cognitive impairment were recruited. 10 patients underwent mental practice combined with physical practice training, and 5 patients only underwent physical practice training. We observed brain activation regions after 4 weeks of training, and explored the correlation of activation changes with functional recovery of the affected hands. The results showed that, after 4 weeks of mental practice combined with physical training, the Fugl-Meyer assessment score for the affected right hand was significantly increased than that after 4 weeks of practice training alone. Functional MRI showed enhanced activation in the left primary somatosensory cortex, attenuated activation intensity in the right primary motor cortex, and enhanced right cerebellar activation observed during the motor imagery task using the affected right hand after mental practice training. The changes in brain cortical activity were related to functional recovery of the hand. Experimental findings indicate that cortical and cerebellar functional reorganization following mental practice contributed to the improvement of hand function.展开更多

The soil microorganisms play a crucial role in soil structure and functioning. They are responsible for soil formation, ecosystem biogeochemistry, cycling of nutrients and degradation of plant residues and xenobiotics. Certain agricultural treatments, such as fertilizers and pesticides applications, crop rotation, or soil amendment addition, influence the composition, abundance and function of bacteria and fungi in the soil ecosystems. Some of these practices have rather negative effects;others can help soil microorganisms by creating a friendlier habitat or providing nutrients. The changes in microbial community structure cannot be fully captured with traditional methods that are limited only to culturable organisms, which represent less than 1% of the whole population. The use of new molecular techniques such as metagenomics offers the possibility to better understand how agriculture affects soil microbiota. Therefore, the main goal of this review is to discuss how common farming practices influence microbial activity in the soil, with a special focus on pesticides, fertilizers, heavy metals and crop rotation. Furthermore, potential practices to mitigate the negative effects of some treatments are suggested and treatments that can beneficially influence soil microbiota are pointed out. Finally, application of metagenomics technique in agriculture and perspectives of developing efficient molecular tools in order to assess soil condition in the context of microbial activities are underlined.展开更多

It was much more active than P-25 and exhibiting good decantability, less deactivation after several runs and less sensitive to pH change. Diffuse reflectance spectra （DRS） revealed that the electronic change in TiO2 did not occur by the addition of AC. Results of SEM and XRD suggested that better TiO2 distribution can be achieved when optimal AC content was adopted. The performance of the prepared TiO2/5AC catalyst revealed great practical potential in wastewater treatment field.展开更多

Results of SEM and XRD suggested that better TiO2 distribution can be achieved when optimal AC content was adopted. The performance of the prepared TiO2/5AC catalyst revealed great practical potential in wastewater treatment field.
