【总结归纳】由于黄赤交角的存在，导致地球在公转轨道的不同位置，太阳直射点位置发生有规律的变化。夏至日时，太阳直射北纬23°26ˊ（北回归线）；冬至日时，太阳直射南纬23°26ˊ（南回归线）。夏至日和冬至日之间的时段，太阳直射点作往返运动。太阳直射点的这种周期性往返运动，称为太阳直射点的回归运动。 【板书】

②在图中画一条直线表示黄道面的位 置。
③图中有一处的画法有错误，请改正。 ④如果黄赤交角减小，寒带、温带、热带的范围大小将会发生什么变化？ 。 【点拨】这道题目是全国高考地理试题中第一次考查学生创新能力，即如果黄赤交角减小，寒带、温带、热带范围大小将会发生什么变化？目前黄赤交角是23°26′，热带的范围是46°52′（南北回归线之间的地区），寒带的范围是90°－23°26′＝66°34′，北温
带的范围是66°34′－23°26′＝43°8′。假设黄赤交角减小到23°，热带的范围是46°，寒带的范围是90°－23°＝67°，北温带的范围是67°－23°＝44°，即热带、寒带范围缩小，温带范围扩大。
【答案】①北回归线 ②黄道面的画法通过北回归线、南回归线与地球表面的交点，地轴与赤道的交点。③正确的画法将北极圈向南移动与晨昏线相交。④热带的范围缩小；寒带的范围也缩小；温带的范围扩大。

【点拨】此题重点检查考生在理解了地理基本规律和原理之后，在给定的时间内，完成逻辑推理和判断。该题是一道一图两设问题，第一和第二设问中都提示中心点为北极，根据平时复习，学生可以确定该图为北半球的俯视图，自转方向为逆时针方向，第一设问中已说明阴影部分为黑夜，因此可确定阴影和非阴影区的界线为晨昏线，进而判断甲地时间为晨线所在经线时间相差3小时，则甲地时间为9时，第①题正确选项是B。图中晨昏线经过极点与经线重合，根据所学知识，晨昏线与经线重合只能在春秋二分，由此判断图中所给时间为春分或秋分，故第②题正确选项A。第二设问中阴影部分为7月6日，非阴影部分为7月7日。
