资料：It’s almost considered sacrilegious today to leave work at the end of your workday or（for shame！）on a Friday and simply not check your work email again until you return the office during normal working hours。

The constant need to check email is the trade-off the modern workforce has made for the ability to work anytime，anywhere，hanks to smartphones and tablets that keep us always connected。

But three university researchers have found that it’s not just doing a bit of work after hours that cause burnout。The true culprit is actually the constant worrying about off-hour email。

A new study。“Exhausted But Unable to Disconnect，”by Lehigh University’s Liuba Belkin，Virginia Tech’s William Becker and Colorado State University's Samantha Conroy shows that employees are growing exhausted by the expectation that they will always be available，never knowing what kind of work requests will be asked of them off hours。

Typically，companies don’t mean to stress employees out like that。Most companies don't have formal policies that say people must answer work emails after-hours，（except，perhaps，in cases where an employee is on call during specific times）。

But policies and culture tend to be two different things。If supervisors routinely email employees after hours and expect a fast response （often because their supervisors are doing the same to them），then the message is clear: whenever the boss emails，the employee is expected to be available。

The solution is for bosses to tell employees that an after-hours email doesn’t necessarily require a response before the next work day，and to also set some times when after-hours emailing is considered acceptable and prohibited，such as no emails via the dinner hour，on weekends，or after 10 p.m.，the researchers say。

Why the study said people are “Exhausted But Unable to Disconnect”？

A.Because they never know what kind of work requests will be asked off hours
B.Because they are required by the company to answer emails off hours
C.Because smart phones and tablets keep us connected all the time
D.None of above

【主题句】第四自然段A new study "Exhausted But Unable to Disconnect." by Lehigh University's Liuba Belkin， Virginia Tech’s William Becker and Colorado State University's Samantha Conroy shows that employees are growing exhausted by the expectation that they will always be available， never knowing what kind of work requests will asked of them off hours.一项新的研究“精疲力竭，但又无法断开”。由莱赫伊大学的卢巴贝尔金、弗吉尼亚理工大学的威廉贝克尔和科罗拉多州立大学的萨曼莎康罗伊共同完成的一项新研究显示，员工们越来越疲惫，因为他们需要随时待命，永远不知道在休息时间会有什么样的工作任务需要他们。

【解析】题目意为“为什么研究说人们‘精疲力竭却无法断开联系’？”选项A意为“因为他们永远不知道下班后将有什么样的工作要求”；选项B意为“因为他们被公司要求下班后依然要回复邮件”；选项C意为“因为智能手机和表格可以使我们一直保持联系”；选项D意为“以上皆不是”。结合主题句，故选A。
