胸脯

The bird swelled out its chest to attract the attention of the female.

那鸟儿把胸脯鼓起来吸引雌鸟。

Sometimes he woke and watched her as she slept: the flutter of her eyelids, the slow even movement of her chest, her outflung hand, small enough that he could enclose it completely with his own.

有时他醒来看着沉睡中的她，她的眼睫毛轻轻眨动，胸脯缓慢而平稳地起伏，一只手伸到一旁，小巧得能让他完全握住。
