2021届高考地理一轮总复习测试卷5:地球公转及其地理意义含解析

2021届高考地理一轮总复习测试卷第五讲地球公转及其地理意义(2019·宁夏育才中学模拟)二十四节气是中华民族古老文明和智慧的结晶,现已正式列入联合国教科文组织人类非物质文化遗产名录。

读二十四节气示意图,回答1~2题。

1.我国教师节(9月10日)期间,最接近的节气是( )A.立秋B.白露C.寒露D.小雪2.下面的时间段中,太阳直射点在北半球且向南移动的是( )A.春分→清明B.小暑→大暑C.霜降→立冬D.大雪→小寒解析:1.B 2.B [第1题,据图可知,相邻两个节气间隔大约为15天。

根据太阳直射点的移动规律可知,我国教师节(9月10日)大致位于9月23日(秋分)前半个月。

由此判断,最接近的节气为白露,故答案选B项。

第2题,据图及地球运动规律可知,春分→清明,太阳直射点由赤道向北移动,A错误;小暑→大暑,太阳直射点在北半球并向南移动,B正确;霜降→立冬,太阳直射点在南半球并向南移动,C错误;大雪→小寒,太阳直射点在南半球且先向南再向北移动,D错误,故答案选B项。

](2019·黑龙江伊春二中期中)表中所列的是12月22日前后甲、乙、丙、丁四地的白昼时间,根据表中数据回答3~5题。

A.甲地B.乙地C.丙地D.丁地4.四地所处纬度从高到低顺序排列的是( )A.甲、乙、丙、丁B.甲、乙、丁、丙C.丙、丁、乙、甲D.丁、丙、乙、甲5.造成四地白昼时间差异的主要因素是( )①地球的公转②地球的自转③黄赤交角的存在④地方时的不同A.①② B.②③C.③④ D.①③解析:3.D 4.B 5.D [第3题,北半球冬至日是12月22日前后,此时北半球昼短夜长,昼长小于12小时。

南半球昼长夜短,昼长大于12小时。

读表格,四地中昼长大于12小时的是丁地,属于南半球的是丁地,D对。

第4题,赤道昼长时间不变,始终是12小时。

其他地点纬度越高,昼长变化幅度越大,即与赤道昼长12小时的差值越大,纬度越高。

根据表格中昼长时间与12小时的差值判断,四地所处纬度从高到低排列顺序,即与赤道昼长差值由大到小的顺序,依次是甲、乙、丁、丙,B对。
