【英语时差8,16】月亮的黑暗面（上）

（单词翻译）

To many folks, the phrase “dark side of the moon” suggests there’s a place you could go to on the moon which is perpetually cloaked in darkness. This is incorrect! Let’s ignore lunar eclipses for now. With that exception, sunlight is always falling on some part of the moon. And, the amount of moon that receives sunlight is roughly one-half. But that doesn’t mean that any given part of the moon is always dark or light. It’s like saying “half the people on earth are always asleep.” That may be so, but it doesn’t mean the same people never wake up. The sun’s light goes around the moon as the moon spins, just as it does the earth.
