适合中学生的分级课外读物，主题多样、角度新颖、轻薄易读，帮孩子通过广泛涉猎各种素材加速过阅读关，还能有效对接未来升学、考试。...
Ladders 是一套在美国本土学校或者国际学校里常用的学科配套读物，覆盖了其中三门学科：Language Arts 语文
Science 科学
Social Studies 社科
这套书在难度上分为三个等级，覆盖国内大多数初中生（甚至高中生）的阅读进程（如果孩子英文学习起步早，从小学中高年级开始读也是合适的）：
L1(G3)：兰斯400L-890L左右，推荐5-7年级孩子；
L2(G4)：兰斯470L-980L左右，推荐6-8年级孩子；
L3(G5)：兰斯630L-1040L左右，推荐7-9年级孩子；
这套读本在三个方面做得非常出色：
1、适合中学生的有趣且易读的英文原版读物很少，Ladders是很难得一见的选择；
2、阅读感受很棒！一流的高清图片，16开大开本，视觉非常震撼，带孩子从这个世界的真实影像中认识万事万物；
3、知识性读物最怕无趣、难读，所幸的是，Ladders一个“毛病”都没有，角度新鲜，还好读！
