National standards of english course ( experimental edition ) explicitly indicates : the focus of reform of english course is to change the situation of putting more emphasis on grammar and lexical explanations , and of the tendency of overlooking learners " language performance on actual occasions . the reform advocates experience , practice , participation , collaborative and communicative learning style and task - oriented approach based on learners " interests , life experience and cognitive level , aiming at developing learners " comprehensive abilities 国家《英语课程标准(实验稿) 》明确指出： “此次英语课程改革的重点就是要改变英语课程过分重视语法和词汇知识的讲解与传授、忽视对学生实际语言运用能力的培养的倾向，强调课程从学生的学习兴趣、生活经验和认知水平出发，倡导体验、实践、参与、合作与交流的学习方式和任务型的教学途径，发展学生的综合语言运用能力。 ”
Part three clearly defines literacy - oriented education and information literacy education , subjectivity instruction and constructivism teaching theories as the theoretical basis of constructing the four - step classroom instructional model of it course in elementary schools , further points out the literacy and subjectivity are the two indivisible parts of human development , introduces and analyses the two major problems existing in the current teaching models of it course : unsuccessful task - oriented instruction , and the difficult control of the differentiation among students . in order to resolve the problems , the four - step classroom teaching model set the following three teaching objectives : general development , everyone development , and characteristic development . also , the four steps , " situated task , teaching and exercising , activity groups , works evaluation " , the actual instructional process and concrete implementation principles are systematically elaborated 第三部分，明确了中小学信息技术课四步课堂教学模式的理论基础是素质教育与信息素质教育，主体性教育思想与建构主义教学论，并指出，素质与主体性是人的发展的两个方面；提出并分析了现有信息技术课课堂教学中存在的任务驱动法难以贯彻、学生差异难以兼顾的问题；针对信息技术课堂教学中存在的问题，中小学信息技术课四步课堂教学模式确立了全面发展、全体发展、个性发展的教学目标；系统阐述了“情境任务?讲练结合?活动分组?作品评价”的四步教学过程及其具体实施要求。
It is pointed out that under the current industry environment logistics enterprises have to form alliances , especially , to develop value - chain relationship on the basis of respective corn competitive ability . as for the form of the relationship , it is proper to found inter - organizational enterprise alliance among logistics enterprises . after that , the article starts to study the virtualization of such enterprise alliance in the net economy , which first gives rise to the idea of virtual logistics enterprise alliance incorporating task - oriented virtual enterprises and resource - dependent logistics enterprises 论文指出了在目前的产业环境下第三方物流企业必须走合作的道路，建立在各自核心竞争力基础上的价值链合作是物流企业的发展思路，紧接着讨论合作的形式问题，论文指出第三方物流企业间组建中间组织性质的企业联盟符合我国的物流产业现状，然后论文开始研究这种企业联盟在网络经济条件下的虚拟化倾向，首次提出了虚拟物流企业联盟的概念，指出虚拟物流企业联盟是基于任务导向性的虚拟企业和基于资源依赖性的物流企业网络组织的有机结合，同时还对虚拟企业联盟的契约特点和相关性质进行了研究。
Compared to obga ( order - based genetic algorithms ) , our algorithm can obtain the result of the higher quality and has the higher ability of globally searching and the shorter time of searching , so having the better feasibility . the task - oriented coalition formation mechanism is an important problem in dps domain 与obga ( order - basedgeneticalgorithms )算法相比，我们的算法具有更好的全局搜索能力，取得了更高质量的解，随着agent数量的增大，这种全局搜索能力更加显现出来；而且，由于我们算法的编码长度较短，所以大大降低了计算量，缩短了运行时间，提高了执行效率。
Strongly advocated in the " new standards for middle school english curriculums " is the task - oriented teaching model for english language ( afterwards as totmel ) based on dozens years " practice of teaching foreign languages in foreign countries and this model implements the cultivation of the overall abilities of using english in the actual process of english teaching and attaches importance to such learning methods as experiencing , practicing , participating , exchanging and cooperating with aims to obtaining information , giving , receiving and accomplishing tasks and achieving purposes of tasks in english 长期以来，我国英语教学过分重视语言知识的传授，忽视综合语言运用能力的培养，致使“高分低能” “聋哑英语”的现象难以消除。英语任务型教学模式是依据国外几十年外语教学实践而建立的，是我国新课程标准所倡导的新型教学模式。该教学模式，把综合语言运用能力的培养落实在教学过程中，倡导体验、实践、参与、交流与合作的学习方式，实现任务的目标，强调在任务的环境中培养学生用英语接受和给予任务、获取信息和完成任务的能力。
