问题描述：
3020104:because of her larger size the female does most of the incubating while the male hunts for enough food to feed them both.
想知道的问题：
1—句尾的for enough food to feed them both.为什么both放在最后什么用法?both可以提前吗?
答
both 称作同位语,只能跟在核心名词或代词后,不能放在前面.在本句中,both 是不定式 to feed 的宾语 them（小鸟和雌鸟）的同位语,因此需要跟在 them 后面.
参考译文（变通翻译）：由于雌鸟个头较大,绝大部分时间由它孵鸟,而雄鸟则捕捉足够多的食物既喂食雏鸟也给雌鸟吃.
