Passage Two
短文二
Setting the office air-conditioning at about 22℃ has become standard practice across the world.
将办公室的空调温度设定在22摄氏度左右已经成了世界各地的标准做法。
Numerous guidebooks across the world on heating, ventilation and air- conditioning claim office performance peaks at 22 degrees.
全球许多关于供暖、通风和空调的手册都声称办公室温度为22 度时，（员工的）工作表现最佳。
Many people indeed find relief from soaring summer temperatures in air-conditioned offices.
许多人的确因为待在开空调的办公室里而避开了夏日的高温。
But recent studies have challenged the accepted wisdom that a cool office is more productive.
但新近研究对“凉快的办公室使人工作效率更高”这一公认的看法提出了质疑。
The reality is more complex.
现实情况更加复杂。
Researchers conducted a review of all studies relating to air- conditioning and productivity.
研究人员回顾了所有与空调和工作效率相关的研究。
They found that 22 degrees was probably a little chilly, even at the height of summer.
他们发现，即使是在盛夏，22度很可能还是有点冷。
For a person dressed in typical summer clothing, an optimal range would be between 23 and 26 degrees.
对于一个穿着典型夏装的人来说，空调的最佳温度范围应该为23度~26度。
And people can even tolerate temperatures beyond this comfort zone as long as they can adjust their clothing and expectations.
而且只要能够增减衣物、调整心理预期，人们甚至可以忍受超出这一舒适区间的温度。
In fact, even on very hot days, it makes sense to turn the air-conditioning up.
确切地说，即使是在非常炎热的日子里，把空调温度调高也是合乎情理的。
People often chase just one optimum temperature, and this is understandable when people feel hot.
人们往往追求一个最佳温度，当人们觉得很热的时候，这是可以理解的。
But there is a range of at least three to four degrees which does not have any adverse impact.
不过，温度至少在三到四度的范围内波动不会产生任何不利影响。
Another issue related to this is that people can become psychologically dependent on air conditioning.
与此相关的另一个问题是，人们可能对空调产生心理依赖。
If they re used to the environment which is air-conditioned, they tend to prefer lower temperatures.
人们如果习惯了空调环境，就会倾向于喜欢较低的温度。
But the studies found that almost all humans became accustomed to the new temperature.
但研究发现，几乎所有人都习惯了新的温度。
It was only at the extreme ends of the temperature range where people's productivity suffered.
只有在（适宜）温度范围的两极，人们的工作效率才会受到影响。
This range was above 26 degrees and below 19 degrees.
（产生影响的）这一温度范围为26度以上和19度以下。
