每日一词学英语(66): to boot

接着昨天，继续讲Larry Walters的故事。话说他飞速窜上天，惊魂未定，忘了饿了，眼镜也丢了。He was way up high, and he was scared and probably not hungry anymore (and had lost his glasses to boot), but now he had another, more immediate problem: He was drifting into the flight path of incoming planes to Los Angeles International Airport. 并且遇到大麻烦：飘进了航班飞行路线。

这里“and had lost his glasses to boot”和靴子无关，“to boot”是(idiomatic) moreover, on top of that, besides, also (Wiktionary)。
*My boyfriend is funny, and a pretty good cook, to boot.
其中“boot”的意思是“【古语】益处；用处”(金山)，“bootless (adj.)”是“无用的，无益的”。
