太阳和影子
太阳高度角影响物体影子长度，太阳高度角越小影子越长，反之则影子越短。一天中太阳高度在日出和日落时都为0°，影子是最长的，而正午时太阳高度角最大，影子为一天中最短的。
Can you answer Little Duck's question, Robin
Yes, the shadow is longer when the angle of the sun is smaller.
Tips:影子的方向总是和太阳的方向相反。一天中早晚影子长,中午影子短；一年中冬季影子长,夏季影子短。
Tips: 太阳刚刚升起或即将落下时影子最长。这时，太阳接近地平线，与地面的夹角（叫太阳的高度角）较小，形成的影子就最长。到中午时，太阳的高度角最大，形成的影子就最短。
Can you answer Little Duck's question, Robin
Yes, the shadow is longer when the angle of the sun is smaller.
