The moon has a lot of looks. And each one happens for a reason.
月亮有很多种面貌，而每一种背后都是有原因的_%e&2,ayCXO]Z;。
It takes the moon about 29 and a half days to orbit around the Earth.
月球绕地球公转的周期约为29天半q=g64By*sX。
And during this time, the sun illuminates the moon from varying angles which creates a shadow effect that we see here on Earth.
在此期间，太阳从不同角度照亮月球，从而就有了我们在地球上看到的阴影效果Xs6k,z9KS^Xn2opvp56J。
At the start of each lunar cycle, the moon is between the earth and the sun.
在每个周期开始时，月球处于地球和太阳之间E58J)6Pb!T;。
This is called a “New Moon”.
这时候的月亮称之为“新月”hN8Qx.GR2FgK~~9。
The side of the moon visible from Earth is not illuminated and therefore we can’t see it.
月球靠近地球的一侧没有被照亮，所以我们才看不见月亮vtM%[V@pZ_aN。
As the angle between the Moon and the Sun increases, so does the amount of moon we’re able to see.
随着月亮和太阳之间的角度变大，我们能够看到的月亮的面积越来越大hgEe;=R5URy]e。
After the new moon, it enters the waxing crescent phase where we can see 1 to 49% of the moon.
新月之后，月亮进入“蛾嵋月”位相，这个阶段我们能看到月亮的1％到49％StAlz^a(!9opKmt。
When it reaches 50% illumination, it becomes a first quarter moon, which is kinda confusing but we’ll roll with it.
当可见度达到50％时，它就变成了“上弦月”，虽然还是有点儿让人莫名其妙，这里我们先把这个问题放一放t,@Lt^YwM[。
Next is the waxing Gibbous phase, which means we can see about half to almost all of the moon.
接下来是盈凸阶段，这也意味着我们可以看到一半左右到将近整个月亮1ajXGPxPm,K2TuI+Uyt。

And finally… we get to see the big cheese.
终于......我们看到大满月了%]xE2H;PFBd4P&5n8d2k。
We get one glorious night of full moon and then the illumination starts to fade.
光辉灿烂的满月之夜终于来临，此后，月亮的亮度又开始逐渐消退%9^+nvo2+eETc00E。
After a full moon, we see the waning phase which is the opposite of waxing.
满月之后就是与渐盈相反的渐亏阶段~G]P,eOHTcMw7_。
The moon follows the same illumination pattern just flipped with the final phase being the waning crescent.
这个阶段，月亮的明暗模式不变，只不过和渐盈阶段反了个方向，结束时变成了“残月”WfD=PK#v,g~izv6,i。
Then it starts all over again with the new moon!
之后月亮重新进入回到新月状态！
The way you see the moon depends on where you are on the globe.
你看到的月亮的模样跟你在地球上所处的位置有关zX-e.89W!+(l*1B)。
If you’re in the Northern Hemisphere,
如果你是在北半球，
a waxing moon will be illuminated on the right side while a waning moon will be illuminated on the left.
那渐盈凸月被照亮的就是右侧，而渐亏凸月被照亮的是左侧U)(B=zc%QDm。
It’s the opposite in the Southern Hemisphere.
南半球的情形则与北半球恰好相反FhdKTJt(hq3YHD。
So now you know, the next time you see a waxing moon, a full moon is right around corner.
所以现在你知道了吧，下次看到渐盈凸月的时候，就表示满月已经不远了;cRE3L|Z,*。
