Is there a link between social media and depression? Do social media have a negative impact on your mental health? It’s complicated.
In a recent study，the investigators compared social media use and depression between teens. 1 Specifically，for every hour per day that one teen spent on social media more than her peers，she likely had a 0.64-point higher depression score.
A different study published in 2018 identified five distinct types of social media users.The finding was that “problematic social media use” was one of the main themes for people whose mental health was affected by social media.You can have alcohol in your life without it being a problem，or your alcohol use may become problematic. 2
There’s one important thing to remember about survey research—just because two things happen together，it’s not necessarily true that one causes the other. 3 For all we know，it could be that people who are already more depressed choose to spend more time on social media.
4 If you think that we shouldn’t paint social media with one broad brush，you’re on the right track.On the one hand，participants often described social media as a valuable way to cope with stress.On the other hand，cyberbullying via social media was also a common experience for participants.Some also said that constantly checking their own social media profile was stressful.
It’s certainly possible that experiences like cyberbullying，comparing yourself to idealized images，and constantly monitoring your profile，are bad for your mood.It’s also true for many that social media offer community support and positive messages.Given the inconclusive research，it’s safe to say that at least we shouldn’t write off social media altogether. 5 Anyway，you cannot use it as a crutch for coping with other stressors and mental health problems.
A．It’s the same with social media.
B．Social media can be a double-edged sword.
C．People get more opinionated about the potential problems of social media.
D．They found that those who used social media more had higher depression scores.
E．They reviewed all existing research and found that there were both benefits and drawbacks.
F．The key to benefiting from social media may lie in using it in moderation and staying socially connected.
G．For example，just because higher social media use co-occurs with higher levels of depression doesn’t mean social media use causes depression.
【答案】 1.D 2.A 3.G 4.B 5.F
【解析】 这是一篇说明文。文章分析了社交媒体的使用和抑郁之间的关系。
1．段中题。空前句表明，“在最近的研究中，调查者比较了解青少年中社交媒体的使用和抑郁之间的关系。”D选项含义“他们发现使用社交媒体更多的人有更高的抑郁分数。”上一句出现了investigators 复数的人，选项中的 they 代指上文可以确定D和E选项，结合句意 ，D选项符合上文所说内容，与前句形成承接。故正确答案是D。
2．段尾题。空前一句表明，“在你的生活中有酒精可能不会成为问题，或者酒精的使用会成为问题。”这句话使用例子来阐述两者之间的关系，结合段落大意，可知这一点在社交媒体中也是适用，选项A中的it指代前面一句话，且符合段落主旨。A选项含义：“它与社交媒体是一样的。”故正确答案是A。
3．段中题。第四段第一句“两件事情一起发生，并不一定意味着一个导致另一个。”，接下来就是解释说明，即G选项“例如，仅仅因为更多地社交媒体的使用与高水平的抑郁同时发生，并不意味着社交媒体的使用引起抑郁。”，举例说明上文，承上启下。故正确答案是G。
4．段首题。空位于段首，常为总起句，因此应选择概括性选项，而避免描述具体细节的选项。B选项“社交媒体可能是双刃剑”，之后全段也是针对社交媒体优缺点的进一步描述。故正确答案是B。
5．段中题。 空前一句肯定社交媒体的存在的合理性，含义“至少我们不应该把社交媒体都取消了”。意思是合理使用社交媒体而不是过度使用，这符合 F 选项所表达的意思“从社交媒体受益的好处就在于适度并且保持社交连接”，因此公司不要把社交媒体当成拐杖去处理负面情绪。故正确答案是F。
