立场问题是爱国主义教育的根本问题,决定人们爱国的思想意识、情感态度、政治站位与行为实践.爱国主义立场是认同和热爱祖国的根本立足点,是爱国思想情感行为的价值耦合点,是爱国爱党爱社会主义的现实立足点.新时代,面对大国利益的战略博弈、多元文化的全球传播以及纷纭复杂的社会思潮的冲击,如何深入探索和科学把握爱国主义立场,是新时代爱国主义教育的重大课题,是建设中国特色社会主义现代化强国、实现中华民族伟大复兴必须思考好、解决好的根本问题.

时代新人是新时代实现中华民族伟大复兴的重要力量,是国家的未来,民族的希望.意志力作为一种精神元素,是时代新人坚定理想信念、提升本领能力、践履责任担当的重要支撑.能否锻造坚定理想、改革创新、攻坚克难、拒腐防变的意志力,是时代新人能否在新时代开展具有新的历史特点的伟大斗争的关键因素.如何砥砺时代新人的坚强意志,助力时代新人投身新时代建设社会主义现代化强国的伟大实践,是新时代事关个人、国家与民族前途命运的重大课题.

农村社会组织的健康发展对重塑农村社会秩序、营造畅通的利益表达机制、促进社会和谐及推进农村法治化进程具有不可替代的作用.目前,农村社会组织存在着结构失衡、制度缺失、公信不足和农民参与程度低等问题,应抓住发展机遇,完善规制体系、营造发展环境、加强管理服务、实施资源整合和创新示范带动加快我国农村社会组织健康发展,推动政府职能转变和统筹城乡发展.

As the principal subject and support of social governance ,social organizations play a critical role in promoting the modernization of the national governance system and capacity .However ,in the existing management system of social organizations ,there are still many problems rooted in the misunderstanding of the social organizations ,w hich leads to the absence of related provisions of the rights and responsibili‐ties and the difficulty of judicial intervention .In order to establish the modern system of social organiza‐tions with“separation between government and community ,clearly defined rights and responsibilities and self‐governing by laws”and promote the legalization of the management of social organizations ,it is es‐sential to start from the construction of the management system of social organizations toward the target of guaranteeing the citizens’ right of association ,to specify the legal status of social organizations ,to im‐prove the responsibility system and to realize the transformation of social organizations from the national pattern to the social one .

Diminishing petroleum reserves and the rapid accumulation of greenhouse gases have prompted an interest in the development of biofuels and oleochemicals from renewable sources.Based on this purpose,fatty acid biosynthesis system,a route for producing high-energy density,liquid biofuels and high-value oleochemicals,has received significant attention.This review first introduced classic E.coli fatty acid biosynthesis system,and summarized recent achievements on the engineering the fatty acid metabolic system to produce fatty acids and fatty acid derivatives.Most importantly,this review introduced the in-depth excavation of the fatty acid biosynthesis pathway by using the in vitro reconstituted system,and engineering the fatty acid metabolic system in vivo according to the obtained information to release the potential of the fatty acid biosynthesis system.
