尽管公司经理们早就了解这些利益，但许多人在这方面所做的少之又少。他们对自己是否能相信员工在没有监督的情况下会全力工作持怀疑态度，并且担心员工会把家庭电话费加到工作花销中，使这些远程工作策略增加额外的费用开支。
六级词汇讲解：
本句的主干是...many have done little about it…其中，while引导的是让步状语从句;形容词短语sceptical of…和concemed about…在句中作状语，对主句进行补充说明;whether引导的是sceptical of的宾语从句;从句the additional expenses…作concemed about的宾语，同时，该从句中又包含as引导的时间状语从句。
sceptical意为“不肯相信的;常怀疑的”。如：
I'm sceptical about your purpose.
我对你的意图持怀疑态度。
六级考点归纳：
该句中的incur和occur形近，但意思和用法却有所区别：
incur意为“遭受，招致”，多作及物动词，后面要接宾语。如：
1)People who smoke incur agreat danger to their health.

2)The factory incurred a heavy loss during the earthquake.
