The reason I'm waving with my left hand is because on the right hand is the emergency cutaway.

我挥动左手的原因是挥动右手表示紧急刹停。

For contrast, look at the combat scenes in Akira Kurosawa's Seven Samurai, and how, every time one of the Samurais kills a bandit, there is a brief cutaway shot to that character.

相比之下，看看黑泽明的《七武士》中的战斗场景，每次一个武士杀死一个强盗，都会有一个简短的剖面图。

The solution architects at SOM  came up with for the WeBank Tower was to create cutaways into each  floor, mixing indoor and outdoor, allowing more daylight and creating  natural ventilation through the building.

SOM 的建筑师为 WeBank Tower 提出的解决方案是在每个楼层创建切口，混合室内和室外，允许更多的日光并通过建筑物创造自然通风。
