What time is it now?

The two boys were camping in the backyard¹. When they couldn't figure out what time it was, the first boy said to the second, "Start singing very loud."
两个男孩子在后院露营，他们不知道到了晚上几点钟。于是，一个男孩对另外一个说：“我们开始大声唱歌就行了。”

"How will that help?" said the second boy.   
“那就会知道时间吗？”第二个男孩问。

"Just do it," insisted the first.
“只管唱吧。”第一个坚持道。

Both boys broke into song, singing at the top of their lungs. Moments later, a neighbor threw open her window and shouted, "Keep it down! Don't you know it's three o'clock in the morning?" 
两个孩子开始大声唱歌，过了一会儿，一个邻居打开窗户喊道：“小声点！你们不知道现在是凌晨三点吗？”
