解题思路:判断物体的运动还是静止,首先选择一个参照物,被研究的物体和参照物之间发生位置的改变,物体处于运动状态.

月亮在白莲花般的云朵里穿行,被研究的物体是月亮,月亮运动,选择的参照物一定和月亮之间发生位置的改变,以谷堆、大地、听故事的人为参照物,月亮和参照物之间几乎是不变的.有时月亮躲在云彩后面,有时出来,如果以云为参照物,可以判断月亮是运动的.
故选D.

点评:
本题考点: 参照物及其选择;运动和静止的相对性.

考点点评: 选定为参照物的物体可以运动的也可以是静止的,如果选定为参照物,参照物就假设为不动.然后判断被研究的物体和参照物之间的位置是否变化.

Two geese are standing on the dry land.Nothing but sand can be seen around.What a terrible sight it is.
The two geese are obviously mom and her child,mom is looking at the sky and sign,then say each words slowly to her child:"Do you believe it had been a rich place before,many geeses are all over this river looking for meal in the morning." The little geese reply:"but,why it has been changed so much,it is just a infertile land,sand and stone are the only things on this land." Mom response:" the reason is this place is really hot,the water are evaporated quilkly,and rarely rain.Animals realized that they couldn't make a living in this land without water,so they moved to other forest,I really miss this land so much that's why I take you to here to look at the place our ancestor has ever lived."
