    If you use social media to chase away loneliness, a new study suggests that 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 scientists from the University of Pittsburgh School of Medicine show a direct relationship between social media usage and feelings of isolation(孤独). In short, the more time you spend on social media, the lonelier you may feel.

    With increasing usage of a large number of apps that allow for endless virtual connectivity, loneliness seems like the last problem social media users would face, but according to Brain A. Primack, the leader of the study, it has the exact opposite effect.

    "Mental health problems and social isolation are widespread among young adults nowadays," Primack said. "We are naturally social creatures, but modern life tends to separate us instead of bringing us together. While it may seem that social media provide opportunities to fill the social void(空白), 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 1,787 U. S. adults aged between 19 and 32 via a questionnaire that asked about the usage frequency and the time they spent on the most popular social media platforms. Eventually, they determined that young adults who are constantly logging in social media are lonelier than those with less social media usage. Frequent exposure to unrealistic descriptions on social media instead of face-to-face social interactions may give people the impression that others are living more happily, and this may make users feel more isolated in comparison.

【答案解析】

这是一篇说明文。一项研究表明，人们在社交媒体上花的时间越多，可能会感到越孤独。

1.A 词义猜测题。由第一段的内容以及第二段的最后一句可知，如果你用社交媒体来排解孤独，一项新的研究表明这是在违反常理。简而言之，你在社交媒体上花的时间越多，可能会感到越孤独。所以通过语境可以判断出，第一段中加下划线的短语"going against the grain"与"Doing it all wrong"意思相近。

2.B 推理判断题。由第四段的最后一句可知，虽然社交媒体似乎提供了填补社交空白的机会，但研究表明，这可能并不是人们过去所希望的解决方案。由此可知，在线互动并不是解决孤独的办法。

3.C 细节理解题。由第五段的第一句可知，Primack和他的团队通过问卷调查了1 787名19岁到32岁的美国成年人的社交媒体习惯，询问他们使用最受欢迎的社交媒体平台的频率和所花费的时间。所以Primack和他的团队是通过做一个调查进行这项研究的。

4.D 主旨大意题。由第二段中的"In short, the more time you spend on social media, the lonelier you may feel"和最后一段中的"Frequent exposure...users feel more isolated in comparison"可知，你花在社交媒体上的时间越多，你可能会感到越孤独。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的印象，相比之下，这可能会让许多用户感到更孤独。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。
