英語六級攻克閱讀關(guān)鍵句234. While company managers have known about t

234. While company managers have known about the benefits for a long time, many have done little about it, sceptical of whether they could trust their employees to work to full capacity without supervision, or concerned about the additional expenses teleworking policies might incur as staff start charging their home phone bills to the business.

譯文　盡管公司經(jīng)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(jiān)督的情況下會全力工作持懷疑態(tài)度，并且擔(dān)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。

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

考點歸納　該句中的incur和occur形近，但意思和用法卻有所區(qū)別：

incur意為“遭受，招致”，多作及物動詞，后面要接賓語。如：

1) People who smoke incur a great danger to their health. 吸煙會大大危及人的健康。

2) The factory incurred a heavy loss during the earthquake. 該廠在地震中蒙受了很大的損失。

occur意為“發(fā)生，出現(xiàn)；想起”，多作不及物動詞，通常不帶賓語。如：

1) It is common for such scenes to occur in movies. 電影中出現(xiàn)此類場景是很正常的。

2) A good idea occurred to me. 我想到了一個好主意。

3) It occured to him that he had a date this evening. 他突然想起來今天晚上有個約會。
