[06:25.20](384,551 km) away from the earth,
[06:29.03]（384，551万公里），
[06:32.86]and,to within a few thousand miles,its distance always remains¹⁰ the same.
[06:36.58]它与地球保持这个距离，变化不超地几千英里。
[06:40.30]Yet a very little observation shows that the moon is not standing¹¹ still.
[06:43.72]然而略加观察就可以发现月球并非静止不动。
[06:47.14]Its distance far the earth remains the same,
[06:49.43]它与地球之间的距离不变，
[06:51.72]but its direction continually changes.
[06:53.90]但其方位却不断变化。
[06:56.08]We find that it is traveling in a circle--
[06:58.65]我们发现月球以圆周或者
[07:01.22]or very nearly a circle--round the earth,
[07:04.01]非常接近圆周绕地球一周。
[07:06.79]going completely round once a month,or,more exactly,once every 27 1/3 days.
[07:11.87]月球是我们在太空中紧近的邻居。
[07:16.95]It is our nearest neighbour in space,
[07:18.87]如同我们自己一样，
[07:20.79]and like ourselves it is kept tied to the earth
[07:23.57]地球引力月球
[07:26.35]by the earth's gravitational pull.
[07:28.34]与球紧紧联系在一起。
[07:30.32]Except for the sun,the moon looks the biggest object in the sky.
[07:34.01]除太阳以外，月球是空中看起来最大的物体。
[07:37.69]Actually it is one of the smallest,
[07:39.82]其实它是最小的天体之一，
[07:41.95]and only looks big because it is so near to us.
[07:44.68]只是因为离我们很近，所以看起来大。
[07:47.41]Its diameter is only 2,160 miles (3,389 kin),
[07:52.39]它的直径只有2160英里（3389公里），
[07:57.36]or a little more than a quarter of the diameter of the earth.
[08:00.29]或者说比地球直径的四分之一略多一点。
[08:03.21]Once a month,or,more exactly,once every 29 1/2 days,
[08:06.90]我们所说的“满月”每月有一次，确切地说，每29天半有一次，
[08:10.58]at the time we call "full moon,"its whole disc looks bright.
[08:13.75]这时整个月面明亮照人。
[08:16.93]At other times only part of it appears bright,
[08:19.87]其它时间，月球只有一部分发亮，
[08:22.80]and we always find that this is the part which faces towards the sun,
[08:26.44]我们发现这正是面朝太阳的那一部分，
[08:30.07]while the part facing away from the sun appears dark.
[08:32.74]而背靠太阳的那部分显得淡无光。
[08:35.42]Artists could make their pictures better if they kept this in mind--
[08:38.20]假使美术家们记住月球只有受到太阳照射的那部分才是明亮的， [08:40.99]only those parts of the moon which are lighted up by the sun are bright.
[08:44.56]他们的绘画也许会更美好。
[08:48.14]This shows that the moon gives no light of its own.
[08:50.66]这也说明月球本身并不发光，
[08:53.19]It merely reflects the light of the sun,
[08:55.46]它如同悬挂在天空中的一面巨大的镜子，
[08:57.73]like a huge mirror hung in the sky.
[09:00.15]仅仅反射太阳光。
[09:02.56]Yet the dark part of the moon's surface is not absolutely black;
[09:05.68]不过月球表面黑暗的并不是绝对的漆黑。
[09:08.81]generally it is just light enough for us to be able to see its outline,
[09:12.39]一般说来它的亮度刚好足以让我们看清它的轮廓，
[09:15.96]so that we speak of seeing "the old moon in the new moon's arms."
[09:19.74]因此我们将这一景色称为“新月抱旧月”。
[09:23.51]The light by which we see the old moon
[09:25.64]看旧月所凭借的光线
[09:27.77]does not come from the sun,but from the earth.
[09:30.45]来自地球而不是太阳。
[09:33.13]We know well how the surface of the sea or of snow,
[09:36.07]我们很清楚海面、雪面
[09:39.00]or even of a wet road,
[09:40.92]或者湿漉漉的路面
[09:42.84]may reflect uncomfortably much of the sun's light on to our faces[09:46.03]如何将大量的太阳光反射到我们的脸上，
[09:49.22]In the same way
[09:50.84]使我们感觉不舒服。
[09:52.46]the surface of the whole earth reflects enough of the sun's light
[09:55.49]整个地球表面同样将充足的太阳光反射到月球表面，
[09:58.52]on to the face of the moon for us to be able to see
[10:01.60]使我们得以看见
[10:04.68] the parts of it which would otherwise be dark.
[10:07.22]本来会是很暗的那部分月面。
[10:09.75]If there were any inhabitants of the moon,
[10:11.97]假使月球上有居民，
[10:14.19]they would see our earth reflecting the light of the sun,
[10:17.27]他们也会见到反射太阳光的地球
[10:20.36]again like a huge mirror hung in the sky.
[10:23.14]如同悬挂在天空中的一面巨大的镜子；
[10:25.92]They would speak of earthlight just as we speak of moonlight.
[10:29.24]他们也会像我们谈论地球之光。
[10:32.56]"The old moon in the new moon' s arms"
[10:34.83]“新月抱旧月”
[10:37.10]is nothing but that part of the moon's surface on which it is night,
[10:40.38]只不过是在夜间被地球
[10:43.66]lighted up by earth light.
[10:45.49]照亮的那部分月面。
[10:47.31]In the same way,
[10:48.84]同样，
[10:50.37]the lunar inhabitants would occasionally see part of our earth in full sunlight,
[10:54.25]月球人有时也会见到地球的一部分阳光普照，
[10:58.13]and the rest lighted only by moonlight;
[11:00.45]而剩下的另一部分被月光照亮，
[11:02.78]they might call this "the old earth in the new earth's arms."
[11:06.04]他们也会把这一景色称为“新地抱旧地”。
