问题 The phrase "capitalising on"(Para. 1) can be substituted by
IT directors feel comfortable because

选项 A、safeguards are no longer really necessary.
B、the remote workforce is expanding rapidly.
C、they are more confident of their network’s safety.
D、their staff get easier access to the internet.

答案C

解析 本题问IT主管们放心采用"remote working"的原因。第二段最后两句"security is very important and IT directors are understandably cautious.But they are now beginning to feel more comfortable about allowing their staff a higher level of access from home".说明一向对安全持谨慎态度的IT directors现在也对远程办公放心了,因为他们对网络安全有信心了。故"他们对网络安全更有信心"正确。安全措施不再真正有必要:IT主管是对安全有信心才放心的,而不是说没有必要采取安全措施。远程工作的人数增加了:第二段第四句"now with the increased availability and use of DSL to home users,re mote working is definitely on the increase"表明远程工作的人数的确增加了,但这并不是IT主管对"remote working"放心的原因。他们的员工更容易上网了:第二段末句"...allowing their staff a higher level of access from home..."是结果,而非原因。另外,用Internet也不准确—此处探讨的是接人公司虚拟局域网的安全性,而非Internet的安全性。
