1、For there to be successful communication ,there must be attentiveness and involvement in the discussion itself by all present.
句中的by是什么意思?for引导的应该是一个目的状语从句吧,像这种“介词+不定式/名词”应该通常都是作状语,可放句首或句末,而且放在句首时后面的逗号可有可无,不知道理解得对不对。
比如:At that time ,it is the bigest one .=It is the bigest one at that time.

(1)对,for引导目的状语从句
(2)可以这样理解,但通常加逗号比较普遍
(3)关于by,意思相当于with respect to; with regard to,表示之前提及的事/物与某某有关,例如你这例句(顺利成功的沟通必须要大家伙儿关注参与讨论)中by是跟discussion,就是指所有在场的人(all present)参与的讨论。另外一种理解就是把by理解为被动中的by,即discussion是“被”all进行的。
