Unit 21 Human Biology
距离高考还有一段时间，不少有经验的老师都会提醒考生，愈是临近高 考，能否咬紧牙关、学会自我调节，态度是否主动积极，安排是否科学合理， 能不能保持良好的心态、以饱满的情绪迎接挑战，其效果往往大不一样。以下 是本人从事10多年教学经验总结出的超实用新高考英语专题复习讲义希望可以 帮助大家提高答题的正确率，希望对你有所帮助，有志者事竟成！
二是上好试卷讲评课。试卷讲评课是高三的主打课型，必须切实收到实效。首 先，要精确掌握考情。考试不过夜，打铁要趁热，每次考试以后，要对班级考 试情况了如指掌，充分了解易错点、易考点，这样讲评时，才能有所侧重，才 能有针对性地攻克重难点。其次，要规范讲评流程。针对错误率高或重点考察 的试题，教师引导出方法思路；再由学生个人进行自评自纠，小组讨论展示， 找出得分原因和失分原因，真正弄清楚解题思路。师生合作再对解题思路进行 再归纳总结，写到纸上记录下来，强化验证结果。三是克服“漏斗思维”。所 谓“漏斗思维”，就是：今天正在学，突然有事不继续了，明天已经忘记一大 部分，后天想起来，继续学，但是忘记的一大部分似乎又需要重新开始，周而 复始，积累数月，结果是仅仅只有一点点的内容，而且是在同一个地方循环往 复。对于常错、常考的知识点，要经常复习，要不就如同漏斗一样慢慢溜掉。 尤其是对于已经进行过的专题训练、变式训练，不能认为进行过一次、两次就 万事大吉，要每隔2周进行“回头看”，把学生的易错题重新编辑，归类整理后 附上分析讲解印发给学生，克服漏斗思维，反复夯实专题训练的知识点。
