  可能说读不懂也不明确,干脆厚脸皮贴一个具体的,看看我的白痴点。求大家指点迷津哦。 讲Moonbow 的,接近不懂状态。
You can see a rainbow when the Sun is low in the sky behind you and it is raining ahead of you. 为啥我必须在中间才能看到呢?
Moonbows occur just after a full Moon, a Moon at its brightest, has risen in the east and just after the Sun has set in the west, and it must also be raining in the west. In this situation, a moonbow may be visible to you if you are facing west and if the Moon is behind you. 月亮东升太阳西落发生在同一时间?为啥必须在西边下雨呢?东边为啥不行呢?
 问的问题都是白痴问题,但是的确是不懂。 大家请帮我看看该如何提高阅读,俺都快发愁跳河了
