（１）A library is a place where people can find out almost anything.
anything似乎用于否定，怎么这样用？？？？
（２）the person goesto the main desk to have a librarian to check the book out
为何要删第二个to？？？
（３）there he almost fell over Mr.wan who was lying at the foot of the stairs.
如何翻译？？

1、anything['eniθiŋ]pron., n.
[用于肯定句]随便什么东西, 任何一种东西, 一切

[用于否定]无论什么; 什么也

[用于疑问句、条件句]什么

[与含有疑问、否定意义的词连用]任何事[物], 什么事[物]

2、删除第三个才对，have作为使役动词用，后面接动词原形
3、他差点跌倒在王先生身上，当时王先生躺在楼梯脚下。
