高中精华双语文章：新月抱旧月 在太空中，月球是离我们地球最近的邻居，约23万9千英里（38万4千551公里）的距离，并始终保持这个距离。月球本身是不发光的，它只能发射出太阳光。而新月抱旧月只不过就是月球表面上正处于黑夜的那一部分被地球的反射光反照的结果。 The Old Moon in the New Moons Arms 新月抱旧月 We find that the moon is about 239,000 miles (384,551 km) away from the earth, and, to within a few thousand miles, its distance always remains the same. Yet a very little observation shows that the moon is not standing till. Its distance from the earth remains the same, but its direction continually changes. We find that it is traveling in a circle - or very nearly a circle - round the earth, going completely round once a month, or, more exactly, once very 27 1/3 days. It is our nearest neighbour in space, and like ourselves it is kept tied to the earth by the earths gravitational pull. 我们发现月球距离地球约23万9千英里（38万4千551公里）。月球与地球总保持这个距离，变化不超过两三千英里。虽然它离地球的距离仍然是那么远，但是它运转的方向却不断地在变。我们发现月球环绕地球的轨道总是圆周形--或很近似圆周形。每一个月，或者更确切些说是每27又1/3天就环绕地球转一圈。在太空中月球是我们最近的邻居。正像我们本身摆脱不了地心吸引力一样，月球也摆脱不了地球的吸引力。 Except for the sun, the moon looks the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2,160 miles (3,389 km), or a little more than a quarter of the diameter of the earth. 除了太阳以外，月球好像天空中最大的天体了。可是实际上它却是最小的天体之一。只是因为它距离我们太近了，所以看起来才显得大。月球的直径只有2160英里（3389公里）仅仅比地球直径的1/4稍多一点。 Once a month, or, more exactly, once every 29 1/2 days, at the time we call full moon, its whole disc looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part facing away from the sun appears dark. Artists could make their pictures better if they kept this in mind - only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It merely reflects the light of the sun, like a huge mirror hung in the sky. 每一个月或者更精确些说每29又1/2天有一次有个我们称之为望月的时候。这个时候整个月亮的圆盘看起来很明亮。在其他一些时候，月亮的圆盘只有一部分看起来觉得亮。我们总是发现这亮的部分是面向着太阳的、面背着太阳的那一部分看起来就黑暗。如果画家们能记住这一点，即只
