题目

We are in receipt of your letter dated Aug 10 ,and as requested was expressed you 3 catalogues for our refrigeration goods
谁帮我解释下这句的语法结构.后半句的.as requested was expressed you 这什么东西啊?怎么俩动词.是错误语法吗
...
也就是说 as requested,was expressed you 3 catalogues for our refrigrnation goods
用了倒装句？是不是本该是：3 catalougues was expressed 那如果这样说，应该用 were啊 因为是3 catalougues啊

答案

as requested was expressed you 3 catalogues for our refrigeration goods
动词没错.as requested应加个逗号,是状语
主语是3 catalogues for our refrigeration goods
谓语是was expressed
句子是被动语态
有点错:you前面加个to
句子翻译:如你要求,三本...目录已快递给你
