For example, birds clap their wings together at the peak of the upstroke during takeoff - that's the clatter of a pigeon taking off in the park - and rotate their wings on the way down to get lift.

例如，鸟儿在起飞上升的顶点合起它们的翅膀——这是公园里鸽子起飞时扑哧的声音——在降落时旋转它们的翅膀以获得升力。

I jumped back to the garage, threw the hammer down on the workbench with a loud clatter, and jumped back to the apartment.

我跳回去车库，将锤子重重地“啪”地一声扔到工作台上，然后回到公寓。
