[SC悬赏令] heavy commitment那道争议题

A Heavy commitment by an executive to a course ofaction, especially if it has worked well in the past, makes it likely to misssigns of incipient trouble or misinterpret them when they do appear. （commitment不如committed好，因为后面miss signs or misinterpret是动作，前面也是动作更加对称(大平行)；miss和misinterpret的行为者不清楚，至少要改为"makes it likely that the executive will miss..."才行；至于后一个it指代后面的不定式没有问题，it充当形式宾语，而实际宾语就是不定式to miss and too misinterpret；has worked…in the past时态错误。）

B An executive who is heavily committed to a course ofaction, especially one that worked well in the past, makes missing signs ofincipient trouble or misinterpreting ones likely when they do appear.（整个句意改变，变成executive makes missing……,即executive本身使得这些错误出现）

C An executive who is heavily committed to a course ofaction is likely to miss or misinterpret signs of incipient trouble when theydo appear, especially if it has worked well in the past.（when they do appear修饰了平行的动词miss or misinterpret不合逻辑，明明miss了还do appear矛盾；especially if it has worked wellin the past远离它修饰的course of action，使得it离所指的a course of action太远不好。）  

D Executives' being heavily committed to a course ofaction, especially if it has worked well in the past, makes them likely to misssigns of incipient trouble or misinterpreting them when they do appear.（而且Executives' being heavily committedto a course of action累赘；has worked…in the past时态错；to miss和misinterpreting不平行；sb’s+v-ing一般属于必错选项）
