影视对白：

Wings that are stretched to gain height one moment. The next are suddenly tucked away as the peregrine slips round in a stoop for her party piece.
翅膀伸出攀升，然后突然收起。游隼俯冲打击猎物。

今天我们要学的单词是：to gain height 爬升

例句：

eg. The air flow can be used to gain height but don't touch the fan.
可通过其气流来升高，不过不要触及它的风扇。

eg. As I gain height I can see across the valley to the plantations of bone-white stone that I visited yesterday.
当我走到高处时，能看见山谷那边种植园里骨白色的岩石，那是我昨天去过的地方。
