【答案】1)赤道() 昼短夜长

2)西 甲 丁

【解析】试题分析:

1)从地球公转轨道图可以看出,当地球公转到A处时,太阳直射赤道,为北半球的春分日,此时全球昼夜等长;当地球公转到C处时,太阳直射赤道,为北半球的秋分日,此时全球昼夜等长;当地球公转到D处时,太阳直射南回归线,为北半球的冬至日,此时北半球白昼最短黑夜最长;当地球运动到CD位置之间时,太阳直射点位于南半球,此时泰安市昼短夜长。

2)从下左图可以看出,根据指向标定向法可知:学校的教学楼位于旗杆的正西方向;冬至日时,北半球的太阳高度角最小,其影子最长,所以甲、乙、丙、丁四幅旗杆影子示意图可知,观测到的是甲幅;614日初中学业考试时,接近夏至日,北半球的太阳高度角较大,其影子较短,所以小明学校的旗杆影子长度最接近丁幅;此时地球应运动在上图中的段。
