[解析]
(1)细节理解题。根据第二段最后一句Even worse,during lunch or walks,that habit of checking would come with me,making my breaks an extension of the workday.(更糟糕的是,在午餐或散步时,查看邮件的习惯也会伴随着我,使我的休息时间变成了工作日的延伸。)可知,该句表明查看邮件的习惯让作者休息时间不放松。故选B。
(2)细节理解题。根据第三段The little red dot on my Gmail app had become a marker of my professional image:the more unread emails,the more I felt I was failing.By quickly responding to everyone,I convinced myself I was seen as reliable by my paymasters and therefore worthy of the work I needed to pay my electricity bills,so I could charge my phone,read my emails and carry on the endless cycle.(我的Gmail应用上的小红点已经成为我职业形象的一个标志:未读邮件越多,我越觉得自己失败。通过快速回复每个人,我让自己相信我的雇主认为我是可靠的,因此我配得上我需要的工作,以支付我的电费,这样我就可以给我的手机充电,查看我的邮件,继续无尽的。)可知,作者快速回复邮件是为维护职业形象。故选C。
(3)推理判断题。根据第四段The content machine kept running and I was busy,producing "word salad" onto the internet.Something needed to change.After a particularly crazy week of nonstop emailing,I deleted the email app.(内容机器一直在运行,我一直在忙着,把"文字沙拉"发布到互联网上。有些需要改变。在一次疯狂的、无休止的电子邮件周之后,我删除了电子邮件应用程序。)可知,结合语境,"word salad"指工作缺乏有意义的内容。故选D。
(4)推理判断题。根据倒数第二段Now,my workdays remain unpredictable,but I've realised that a lack of structure needn't stop me setting boundaries (边界) for myself.Uninterrupted breaks help me focus when I get back to work.Taking a few hours to respond to messages —instead of just minutes —often makes no difference to the sender and allows me to digest the content properly.(现在,我的工作日仍然不可预测,但我已经意识到,缺乏结构并不妨碍我为自己设定界限。当我重新开始工作时,不受打扰的休息帮助集中精力。花几个小时回复信息——而不是几分钟——通常对发件人没有影响,也让我能够充分消化内容。)可知,作者通过设定界限提高了工作效率。故选C。
