The third card (up) turns over (down) and is placed on top of the second card --- also down.

第三张牌（面朝上的）翻过来（面朝下），盖在第二张牌之上——第二张牌也是面朝下的。

My second card is the earth's shadow: When cast on the moon during eclipses, it appears to be the shadow of a round object.

我的第二张牌是地球的影子：月食期间，地球投在月亮上的影子看上去呈圆形物体状。
