前　　言
在一线教学的过程中，我们发现中学的老师和学生普遍都希望有一本能够跟各年级、各学科教材适配的练习册，从而帮助学生更高效地进行课后自主巩固学习，同时也帮助老师将更多的时间和重心放在呈现更优质的课堂上。
基于这一需求，我们组织了从事中学各学科一线教学的资深教师，从构建知识体系、夯实基础知识、突破重点难点、培养学科素养四个方面出发，力求将初、高中各学科的教学体系完整地呈现给读者，同时引导读者通过对经典题目由易到难、循序渐进地练习，达到掌握学科知识、提升学科素养的目标。这就终形成了这套初、高中各学科的“每周必刷题”系列图书。
本系列图书以周为单位、以训练为小单元，科学、系统地陪伴读者完成每个学期的学习，帮助读者从以下几个方面提升自身能力和竞争力。
在学科体系方面，我们为每周的学习内容配备了知识导图，帮助读者从整体上把握本周所学的重点内容，同时也便于读者在复习阶段发现自己的薄弱环节，查漏补缺。
在学科知识方面，我们从基础、能力两个层面设计练习题，帮助读者夯实基础、提高能力。我们还对历年中、高考真题的考点分布及对应的考频做了深入的分析，同时结合模考试卷，选取适合各个学习阶段的题目，帮助学有余力的读者完成知识进阶。
