In the foreignLanguages Bookstore are to be found books in various languages.
这里面为何要用are to be found 不能直接用 are found 吗？
In the foreign Languages Bookstore are to befound books in various languages.
这是一个倒装句。恢复正常语序为：
Books in various languages are to be found inthe Foreign Language Bookstore.
这是be to do结构表示以后时间。这种结构表示安排、计划、命令、注定会在以后发生的事件。你可以近似地理解为will do. 即are to befound大约等于will be found.
