影子是我们最亲密的伙伴。太阳给了我们影子，花，草，树，木的生长也需要太阳。所以本次，我们组研究的是太阳高度。通过一整天的拍摄，我们感受到了科学家的辛苦，他们不畏严寒酷暑，勇往直前。从我们的测量，总结出高度角越大，影子越短，角度越小，影子越长。正午为一个地区太阳高度角最大的时间；一点到两点，为一个地区温度最高的时间。我们同时绘制了统计图，方便观察。这次的拍摄，我们都汗流浃背，感受深刻。 

Shadow is our closest companion. The sun gives us shadow. The growth of flowers, grass and trees also needs the sun. So this time, our group is studying the solar elevation angle. Through a whole day of shooting, we feel the hard work of scientists. They are not afraid of the cold and heat. They march forward bravely. From our measurement, we conclude that the larger the solar elevation angle is, the shorter the shadow is, and the smaller the angle is, the longer the shadow is. Noon is the time when the solar elevation angle is the largest in a region; One to two is the time when the temperature is the highest in an area. At the same time, we draw a statistical chart to facilitate observation.Everything that happened on this day will always be remembered.
