有一天晚上我翻来覆去睡不着,天快亮的时候,干脆爬起来,走到阳台上去。这时候天已经微微有点亮了,可是突然,那些亮光消失了,天空变得特别黑,不一会儿又亮了。我一下子想起了“黎明前的黑暗”这句话。这里面有什么科学道理吗? One night I couldn’t sleep over and over, and when it was dawning, I simply got up and went to the balcony. At this time, the sky was slightly lightened, but suddenly, those lights disappeared, and the sky became particularly dark, and it soon became bright again. I suddenly remembered the words “darkness before dawn”. Is there any scientific reason here?
