【题目】通过学习,我们了解了地球的形状和大小。下列现象或实验,不能证明地球是球体的是( )

A. 麦哲伦环球航行 B. 日食 C. 月食 D. 海平面上船只的出没

【答案】B

【解析】

能证明地球形状是球体的例子很多:站得高,才能看得远、麦哲伦环球航行、人造卫星拍摄的地球照片、远处驶来的帆船总是先看到桅杆,再看到船身、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等。

地球卫星照片、麦哲伦船队环球航行,站在海边看远处驶来的帆船总是先看到桅杆,再看到船身、能证明地球是个球体。月食是地球在月亮上的投影,从形状可以证明地球是圆的。日食月亮挡住了太阳照射到地球上的光。不能证明地球是一个球体。故选B。

④以人为本是检验一个故事生命力的主要标准。

⑤在信息过量时代,有内容的故事未必能取得良好的国际传播效果。

⑥正如冯友兰所说:“人类所有之真、善、美,历史多与以相当的地位。其未得相当的地位者,则多其不真真、不真善、不真美者也。”
