1.___Driven______(drive) by a greater demand for vegetables，farmers have built more greenhouses.（过去分词用作状语从句）

分析：状语从句中的动词mail和主句中的主语the email是被动关系：邮件被邮寄。所以用过去分词mailed。
3.__Discussed_/ Having been discussed________(discuss) several times, he can complete his painting.（过去分词用作状语）
分析：状语从句中的动词discuss和主句中的主语he是被动关系：他被讨论。所以用过去分词discussed。
