If you use social media to chase away loneliness, a new study suggests you're going against the grain.
We may have heard a lot about the benefits of interacting with others online, but the findings of a study conducted by University of Pittsburgh School of Medicine scientists show a direct relationship between social media usage and feelings of isolation (隔绝). In short, the more time you spend on social media, the lonelier you may feel.
With increased interaction on a large number of apps that allow for endless virtual connectivity, loneliness seems like the last problem frequent social media users would face, but according to the leader of the study Brain Primack, it has the exact opposite effect.
“Mental health problems and social isolation are at widespread levels among young adults nowadays，” Primack said, “We are naturally social creature, but modern life tends to separate us instead of bringing us together. While it may seem that social media presents opportunities to fill the social void (空隙), I think this study suggests that it may not be the solution people were hoping for.”
Primack and his team examined the social media habits of 1787 US adults aged 19 to 32 via a questionnaire that asked about the time and frequency they spent on the most popular social media platforms. Eventually, they determined that young adults who are constantly logging into social media reported more feelings of isolation than those with less social media usage. Frequent exposure to unrealistic descriptions on social media instead of facetoface social interactions may give people the impression that others are living happier, more connected lives, and this makes users feel more socially isolated in comparison.
这是一篇说明文。研究表明，花在社交媒体上的时间越多，人们可能越会感到孤独。
1．What does the underlined phrase “going against the grain” in Paragraph 1 mean?
A．Doing it all wrong. B．On the way to success.
C．Taking a risk. D．Making a difference.
答案：A
解析：词义猜测题。由第一段“If you use social media to chase away loneliness, a new study suggests you're going against the grain.”以及第二段“ In short, the more time you spend on social media, the lonelier you may feel.”可知，如果你用社交媒体来驱赶孤独，一项新的研究表明，你这是在逆水行舟。简而言之，你花在社交媒体上的时间越多，你可能越会感到孤独。所以通过下文的语境可以判断出，第1段中加下划线的短语“going against the grain”是doing it all wrong“都做错了”的意思。故A选项正确。
2．How did Primack and his team conduct the study?
A．By providing explanations.
B．By collecting data online.
C．By doing a survey.
D．By describing their own experiences.
答案：C
解析：细节理解题。由第五段“Primack and his team examined the social media habits of 1,787 US adults aged 19 to 32 via a questionnaire that asked about the time and frequency they spent on the most popular social media platforms”可知，Primack和他的团队通过问卷形式调查了1 787名年龄在19岁到32岁之间的美国成年人的社交媒体习惯，问卷调查了他们在最受欢迎的社交媒体平台上花费的时间和频率。所以Primack和他的团队是通过做一个调查进行这项研究的。故C选项正确。
3．What can we learn from the study?
A．You will feel happier if you spend more time online.
B．Interaction online is not the solution to social isolation.
C．Virtual connectivity is best way to fill the social void.
D．Popular social media platforms can bring people together.
答案：B
解析：推理判断题。由第四段“While it may seem that social media presents opportunities to fill the social void (空隙), I think this study suggests that it may not be the solution people were hoping for.”可知，虽然社交媒体似乎提供了填补社会空白的机会，但我认为这项研究表明，这可能不是人们希望的解决方案。所以我们能从研究中得到，在线互动并不是解决社交孤独的办法。故B选项正确。
4．What does the text mainly tell us?
A．New study on social media usage has been published.
B．Facetoface social interactions are on the way out.
C．Social media does users more harm than good.
D．Social media might make loneliness worse.
答案：D
解析：主旨大意题。由第二段“ In short, the more time you spend on social media, the lonelier you may feel.”和最后一段“Frequent exposure to unrealistic descriptions on social media instead of facetoface social interactions may give people the impression that others are living happier, more connected lives, and this makes users feel more socially isolated in comparison.”可知，简而言之，你花在社交媒体上的时间越多，你可能越会感到孤独。频繁地在社交媒体上看到不真实的描述，而不是面对面的社交互动，可能会给人一种其他人生活更快乐、交流更密切的印象，相比之下，这可能会让许多用户感到更孤独。所以社交媒体，并没有起到积极的作用，相反它让人更加孤独。所以综合几个段落的主要信息，可以判断出，本文主要告诉我们社交媒体可能会使孤独感更严重。故D选项正确。
