    【题目】人类认识地球有一个漫长的历史过程，下面现象能证明地球形状的是（ ）

    ①日月都从天空东方升起，西方落下②1519-1522年，麦哲伦船队环球航行成功③地球表面积为5.1亿平方千米 ④月食现象

    A.①②B.②③C.③④D.②④

    【答案】D

    【解析】

    根据，人类对地球的认识经过了漫长的过程，从天圆地方→天如斗笠，地如覆盘→麦哲伦环球航行→地球的卫星照片，后来证实了地球是一个两极部位稍扁的不规则球体进行分析解答。

    地球是两极部位略扁、赤道略鼓的不规则的球体。能证明地球形状的例子很多，如：麦哲伦船队环球航行；月食尤其是月环食时，可以看到地球挡在太阳和月球之间的影子，月食就是地球在月亮上的投影，从形状可以证明地球是圆的；在外太空观察以及地球的卫星照片等等。故选：D。
