快速决策可以是重要的防御机制；在判断某人是否是个危险人物时，我们的大脑和身体会自发地在几毫秒内做出快速反应。

Snap decisions can be important defense mechanisms; if we are judging whether someone is dangerous, our brains and bodies are hard-wired to react very quickly, within milliseconds.

这有一些自发进行的化学反应，这一个。

So here are some spontaneous chemical changes here's one.

this happens spontaneously, you actually get energy out of the reaction as this happens.

这是自发的，当反应发生的时候,你会自发地放出能量。

Just to illustrate the kind of issues that we're up against here, let me just consider a few different chemical reactions, all of which happen spontaneously.

为了说明我们的观点,考虑一些，不同的化学反应，这些化学反应都是自发进行的。
