Welcome to English in a Minute.
欢迎收听《一分钟英语》。
If you have heard American English or watched an American TV show, you probably have heard this:" Hear a pin drop."
如果你听过美式英语或者看过美国电视，你可能听到过“Hear a pin drop（异常安静）”。
What does this phrase mean?
这个短语是什么意思呢？
Let's see whether we can find out by listening to an American English conversation.
下面来听听一个美式对话，看看我们能否找到该短语所要表达的意思。
A: I can't believe he said that. And then the room was so quite. Nobody said a word.
A：我不能相信他所说的。之后房间变得很安静。没有人说话。
B: Really?

A: Yeah, I mean it was so quiet you could hear a pin drop.
B：真的？

A：是呀，真是安静的连针掉在地上都听得见。
Pins are small and don't make noise when they fall to the floor.
针是很小的。当它们调到地上时，是不会发出很大的噪音的。
So when you say you can "hear a pin drop," it means that the room is silent.
所以当你说你可以“听见针掉在地上的”，这意味着房间很安静。
Usually, that's because the people are surprised or excited about something.
一般来说，是因为人们对某事感到惊讶或者兴奋（地说不出话）。
And that's English in a Minute.
