If there is a if

It is OK to go past the red lights if you are turning a corner or if there isn't any other traffic around.

如果你在转弯或者周围没有其他车辆，闯红灯是可以的。

For instance, if the host casually acknowledges that there is a camera in the room by telling a story about it, that may be enough to provide an opening for a guest to say if they are uncomfortable.

例如，如果主人通过讲故事的方法，不经意地提及房间里有一台摄像机，这可能就足以为客人提供说出自己的不满的机会。

快速检查一下伤者是否在流血，是否有脉搏。
