小题1:根据图示的太阳直射点位置判断:①位置太阳直射点位于北回归线上,故判断为夏至日;③位置太阳直射点位于南回归线上,判断为冬至日,故②表示秋分日,④表示春分日,兰州白昼最短为冬至日,故选C项。

小题2:结合上题分析,地球公转速度的变化规律:近日点(1月初)最快,远日点(7月初)最慢,故图示从①到②地球公转经过远日点,公转速度先变慢再变快;②到③地球公转逐渐接近近日点,故公转速度不断加快,B项正确;③到④地球公转经过近日点,故公转速度先变快,再变慢;④到①地球公转逐渐接近远日点,故公转速度不断变慢。

点评:本题难度不大,解题的关键是抓住二分二至日太阳直射点的位置,并结合地球公转速度的变化等内容分析,对于此类试题,学生应在平时的学习中加强对相互具有联系性知识内容的归纳与总结。
