Why we’re addicted to email—and how to fix it
In today’s digital world, we’re often expected to be on email at all times. (背景句) Recent studies show that office workers spend almost a third of their workday reading and responding to messages.(举例子) This constant connectivity can be harmful: scientists have established a clear link between spending time on email and feeling stress. （论据论点）（注意冒号的用法，pte考生的swt里用来解释细节的时候可以借鉴）
So why do we do it? Many of us are addicted: checking email activates a primal impulse in our brains to seek out what behavioral psychologists call “random rewards.”（主体段重点解释random rewards带来的效应。） Imagine email as a slot machine.长短句交替，增加句式多样性 Most of the time when we “pull the lever” to check our messages,（要想句式多样，状语前置也是个方法） we get something bothersome—a complaint from a client, a request from our boss.（something这样抽象的东西后面永远有细节支撑） But every once in a while （状语前置） we get something exciting—（除了冒号，破折号也可以用来解释）a note from a friend or (if we’re really lucky) a video of goats jumping on things. It’s those random rewards, mixed in with all the mind-numbing updates, that we find so addictive. Moreover,（段内逻辑递进） the mere fact that someone took the time to write us an email activates a deep-seated (根深蒂固，马丁路德金的演讲里也有deeply rooted的用法可以替代） social behaviour: the desire to reciprocate like with like, which can create unrealistic expectations for how much we can take on.
But striving for inbox zero is, of course, a Sisyphean effort （注意积累文学常识，提升语言能力，PTE写作分项要求）at best. Just when you think the task is complete—ping!（拟声词，语言生动形象，多为中国学生所忽略，当然议论文体也可以不用）—a new message rolls in. What can we do about it? With email—as with everything else in life—we must learn to say no to some opportunities, in order to say yes to our priorities.（金句）
