南湖是长春最大的公园，水面面积达92万平方米．
（1）南湖对周围气温起到很好的调节作用，这是由于水的比热容较______．
（2）在湖面上划船时，船相对于岸是______ （选填“运动”或“静止”）的．
（3）漫步在湖边林荫路上，闻到阵阵花香，这表明分子在不停地做______运动，树荫是由于光的______形成的．
（1）水上公园水多，因为水的比热容较大，白天，相同质量的水和沙石比较，吸收相同的热量，水的温度升高的少；夜晚，放出相同的热量，水的温度降低的少，使得昼夜的温差小，对周围气温起到很好的调节作用能．
（2）坐在船上的游客相对河岸发生了位置的改变，是运动的．
（3）闻到阵阵花香，说明花的分子在不停地做无规则运动．影子、树荫都是由于光的直线传播形成的．
故答案为：（1）大；（2）运动；（3）无规则，直线传播．
