第234句：

While company managers have known about the benefits for a long time, many have done little about it, sceptlcal of whether they could trust theIr employees to work to full capacity wlthout supervision, or concemed about the additional expenses teleworking policieS might Incur as staff start charging their home phone bills to the business.

盡管公司經理們早就了解這些利益，但許多人在這方面所做的少之又少。他們對自己是否能相信員工在沒有監督的情況下會全力工作持懷疑態度，并且擔心員工會把家庭電話費加到工作花銷中，使這些遠程工作策略增加額外的費用開支。

六級詞匯講解:

本句的主干是...many have done little about it...其中，while引導的是讓步狀語從句；形容詞短語sceptical of..和concemed about...在句中作狀語，對主句進行補充說明；whether引導的是sceptical of的賓語從句；從句the additional expenses...作concemed about的賓語，同時，該從句中又包含as引導的時間狀語從句。

sceptical意為“不肯相信的；常懷疑的”。如：

I'm sceptical about your purpose.

我對你的意圖持懷疑態度。

六級考點歸納：
