With the increasing development of China’economy and society,the communication between China and other countries is on the rise,which contribute to the increasing demands of foreign languages especially English.As a result,oral English plays an important role in English learning and it is necessary for learners to improve their oral English.While the traditional teaching models cannot meet the teaching demand now,Constructivist learning theory(CLT),a very important branch of the cognitive theory has arisen a considerable amount of interest as a new teaching method.In the paper,the author try to apply constructivist learning theory to vocational college oral English teaching in order to explore some oral English teaching models from a constructivist perspective and hopes that this paper can provide some help to apply the CLT to vocational oral English teaching. 展开更多

Climate change strongly affected the structure and functions of natural ecosystems,e.g.the vegetation productivity decreased in the Northeast permafrost region due to the higher temperature and less precipitation,whereas in the Tibetan Plateau,the vegetation productivity increased,owing to the improved thermal resource.Climate change led to reduced precipitation in North and Northeast China and thus the reduced surface runoff.The public needs for energy were changed because of climate change,e.g.the shorter heating period in winter.Climate change profoundly influenced human health,pathophoresis and major projects by increasing extreme events,including frequency and magnitude,and causing more serious water shortage.Under the background of climate change,although the improved thermal resources can be helpful for extending the crop growth period,more extreme events may resulted in more instability in agricultural productivity.Not only did climate change indirectly affect the secondary and tertiary industries through the impacts on agriculture and natural resources,but also climate change mitigation measures,such as carbon tax,tariff and trading,had extensive and profound influences on the socioeconomic system.Further analysis indicated that the impact of climate change presented significant regional differences.The impact had its pros and cons,while the advantages outweighed the disadvantages.Based on the above analysis on the impacts of climate change,we put forward suggestions on coping with climate change.First,scientifically dealing with climate change will need to seek advantages while avoiding the disadvantages of climate change in order to achieve the orderly adaptation to climate change,which is characterized with"Overall best,long-term benefit."Second,quantitative adaptation should be given more attention,e.g.proposing operational schemes and predictable goals and using uncertainty analysis on adaptation measures.Third,more active coping strategy should be adopted to enhance China's future comprehensive competitiveness.The strategies include but are not limited to gradually adjusting the industrial structure,intensifying the research and development(R&D)of emission reduction technology and actively responding to the influence of carbon tax,tariff and trading on socioeconomic development in China. 展开更多

In China the desire to be taller is high (excuse the pun), despite people's genetic make-up. It's a desire driven by the sheer volume of folk competing for partners, promotions and prime job offerings, where any advantage is sought in order to get a foot in the door. And with the vast numbers of job seekers competing for positions, recruiters behind those doors can afford to be picky. The word on the street is height means rapid advancement through the ranks. Many young professionals hold the common belief that taller people have more opportunity for promotion in the desperate climb up the corporate ladder. 展开更多

It can be induced by a variety of events such as hypoxia, nutrient-starvation, and mechanical damage. Many neurological disorders such Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis, Huntington’s disease, cerebral ischemia, and acute spinal cord injury (ASCI), are closely related to autophagy. However, therapeutic strategies to manipulate autophagy have not yet been fully deciphered due to the limited knowledge of the molecular mechanisms underlying autophagy in these disorders. 展开更多
