Unit 3 Computers(建议用时：50分钟)Ⅰ.阅读理解A(2024·桂林、崇左联合模拟)Unless you’re very young orvery old, it’s likely you have some kind of relationship withemail, whether you get hundreds of messages a day or a few dozena week. A new study suggests that how we deal with these incomingmessages could be affecting our stress levels and overall health.A team from the Future Work Centre in the UK surveyed 2，000 people across various industries, sectors, and job roles, asking participants how they managed their email and how much associated stress they felt as a result. Overall, those who spent the most time organising and staying on top of messages felt the most emailrelated pressure too.“While email can be a valuable communication tool, it’s clear that it’s a source of stress and frustration for many of us. The people who reported it being most useful to them also reported the highest levels of email pressure.” said one of the team, Richard MacKinnon.Two of the habits linked to more ema ilrelated stress were checki ng for messages first thing in the morning and last thing at night. Half of those surveyed had push notifications(消息推送) set up for new email, while 62 percent of respondents left their email app open all day and all night. Both were linked to higher levels of email pressure. The survey also found that managers suffered more than nonmanagers.Stress is not just a problem when it comes to our mood—it’s been linked to a lot of disorders such as heart disease, weight gain, memory impairment(减弱), digestive problems, and depression.The researchers suggest that the relationship between emailrelated stress and the negative impact on home life is not the same for everyone.【解题导语】大部分人会接触到电子邮件，对电子邮件的处理方式会影响我们的压力层级和整体健康。
