5. Then how about our workplace? Nearly a decade ago, one had to sit in the office all day long. Not so now though! Many companies, whether headquarters or affiliates, actively encourage working from home, and this is becoming more and more common as employers realize that employees do not require round-the-clock monitoring in the completion of their daily tasks. In addition, technology has led to the widespread use of online video conferences; as a result, colleagues are no longer obliged to even meet in the same building.Why do more companies encourage working from home?A It is an effective way to cut costs.B Employees don't need constant monitoring.C Employees can work more efficiently at home.D More companies are located far from the city center.

我们来一步一步分析这道题目。 题目问的是：**为什么越来越多的公司鼓励在家工作？** 我们先来看原文第五段的内容： > "Nearly a decade ago, one had to sit in the office all day long. Not so now though! Many companies, whether headquarters or affiliates, actively encourage working from home, and this is becoming more and more common as employers realize that employees do not require round-the-clock monitoring in the completion of their daily tasks. In addition, technology has led to the widespread use of online video conferences; as a result, colleagues are no longer obliged to even meet in the same building." 我们逐句翻译并理解： - “将近十年前，人们必须整天坐在办公室里。” - “但现在不一样了！” - “许多公司，无论是总部还是分支机构，都在积极鼓励在家工作。” - “这种情况越来越普遍，因为雇主们意识到，员工在完成日常工作时，并不需要全天候的监督。” - “此外，技术的发展使得在线视频会议被广泛使用；因此，同事甚至不再需要在同一个建筑物里见面。” 从这段话中，我们可以提取出两个主要原因： 1. 雇主意识到员工**不需要全天候被监督**（round-the-clock monitoring）也能完成工作。 2. 技术的发展（如视频会议）使得远程办公成为可能。 题目问的是“为什么越来越多的公司鼓励在家工作？”，我们要找的是最直接的原因。 现在来看选项： A. It is an effective way to cut costs. （这是一种有效的降低成本的方式。） → 原文**没有提到成本问题**，比如节省办公室租金或水电等。所以这个选项**没有依据**，排除。 B. Employees don't need constant monitoring. （员工不需要持续的监督。） → 这与原文中“employers realize that employees do not require round-the-clock monitoring”完全对应。这是文中明确提到的原因。 C. Employees can work more efficiently at home. （员工在家能更高效地工作。） → 原文**没有提到效率提高**，只是说不需要监督，并没说在家工作效率更高。所以这个选项属于**过度推断**，排除。 D. More companies are located far from the city center. （越来越多的公司位于远离市中心的地方。） → 原文**完全没有提到公司地理位置的变化**，所以这个选项也**没有依据**，排除。 因此，正确答案是 **B**。 --- **答案：** \boxed{B}
