《普通高中语文课程标准》（2017年版）有三个值得关注的关键词：一个是“语文学科核心素养”，一个是“思维”，另一个是“学习任务群”。“语文核心素养”是纲领和目的，“思维”是关键着力点，“学习任务群”是途径和载体。 本研究将解决“思辨性阅读与表达”学习任务群教学“教什么”和“怎么教”的问题。分为五个部分四个章节：绪论部分分析研究背景，研究意义，研究现状，研究方法，研究创新之处等；第一章根据高中学生问卷调查和教师访谈，了解学生思辨性阅读和表达能力现状及高中语文“思辨性阅读与表达”学习任务群教学现状，总结出学生基础薄弱、教师自身思辨教学能力不足、教科书滞后等问题；第二章根据研究新课标中“思辨性阅读与表达”学习任务群的表述和要求，梳理现行必修教材中可以作为教学内容的选文，构建教学内容体系；第三章从学习任务群教学形式、“思辨性阅读与表达”能力培养、课堂实施三个角度来探究“思辨性阅读与表达”学习任务群教学策略；第四章将本人梳理的教学内容和研究的教学策略应用到教学实践中，在实践中检测其合理性，对实践结果进行总结和反思，发现新的问题，并探究解决方案。 万事开头难，在新课标、新教材的背景下，本研究将有助于构建高中语文学习任务群教学内容体系与课堂教学模式，为一线教师的教学实践提供参考。

There are three key words worth paying attention to in the General High School Chinese Curriculum Standard (edition 2017): The first one is “core literacy of Chinese subject" which is the program and purpose, the second one is "thinking" which is the key breakthrough point, and the last one is "learning task group" which is the approach and carrier. This study will try to find the answer of "how to teach" and "what to teach" in "critical reading and expression" learning task group teaching and consists of five parts or four chapters. The preface part analyzes the research background, research significance, research status, research methods, research innovation, etc. In the first chapter, it was found that the students hold very weak base and teachers lack of critical teaching ability as well as un-advanced textbook, based on the questionnaire survey of high school students and teacher interviews regarding the current situation of students' critical reading and expression ability and "critical reading and expression" learning task group. In the second chapter, the articles that could be used as teaching contents in the compulsory teaching materials were sorted out to construct the teaching content system, according to the expression and requirements of the "critical reading and expression" learning task group in the new curriculum standard. In the third chapter, we try to find the teaching strategy of "critical reading and expression" learning task group from three perspectives: Learning task group teaching form, the ability development of "critical reading and expression" and the classroom implementation. In the fourth chapter, the teaching content and the teaching strategy which were extracted by myself was applied to teaching practice to verify its rationality, and new problems are found and solved thereafter after summarizing the practice mentioned aforesaid. Though everything are difficult at the beginning, this study will help to construct the curriculum and classroom teaching model of Chinese learning task group in high school and provide certain reference for the teaching practice of front-line teachers, under the background of new curriculum standards and new textbooks.
