Keep your pants on, man.

裤子就不必了，伙计。

So, you have parts of your brain that are basically telling you now, largely in the frontal lobes, that are — "Okay." Keep your pants on.

现在在你的大脑中，会有脑组织告诉你，主要是额叶，“好了，穿好裤子。”

“Damn,”he responded. “Of all the graduate students I’ve had here, you are the first guy to do something like that. I’ ll take care of this, but you better keep your pants on from now on!”

“够了！”他回答。“这里这么多年来，我还是头一次遇到你这种事。 这次我会处理，但你今后给我管好你的裤裆！”

Should you keep it in your bag, on your belt, in your pants or shirt pocket?

应该把手机放在哪，包里、衣服口袋，还是挂在腰带上？

If you keep your feet firmly on the ground, you'll have trouble putting on your pants.

如果你始终脚踏实地，那就别想穿裤子了。
