问题 It’s no secret that scrolling through endless images and announcements
of engagements, vacations, new babies and job promotions can make you
feel like you’re not accomplishing anything. But it’s pretty much
impossible to log off forever and never look back on. 【S1】______
Here’s the good news: There might be a sweet spot when it comes to
the amount of time you spend on social media. Keep your use down to just 【S2】______
30 minutes a day can lead to better mental health outcomes, according to
research being published in December in the Journal of Social and Clinical
Psychology.
Researchers from the University of Pennsylvania monitored the
participants’ social media use for a week cross three platforms—Facebook, 【S3】______
Instagram and Snapchat—to get a baseline. Then researchers gauged the
students’ mental health based on seven different factors: social support,
fear of missing out, loneliness, self-acceptance, self-esteem, anxieties, 【S4】______
and depression. Next, the authors separated the students from groups and 【S5】______
conducted the experiment for three weeks. One group was told to keep
using social media as usually: another group was tasked with limiting 【S6】______
social media use to 10 minutes per platform a day.
Researchers then looked at why the students fared in the seven 【S7】______
categories after the experiment. When study volunteers cut down their
social media use to 30 minutes per day total, they experienced a
" significant improvement in well-being" , exhibiting reduced loneliness
and depression, the authors wrote.
There are a few caveats with this study: The participants only used
iPhones in the experiment. The study also only monitored students who
used Instagram, Facebook and Snapchat, but it doesn’t reflect experiences 【S8】______
with other social media platforms.
All that aside, there is something to be said for limiting social media
while still being realistic about the fact you’re never going to ditch it 【S9】______
entirely. Research has shown that excessive Facebook use can contribute to
increase depression and loneliness, and a 2014 study found that social 【S10】______
media use can create social comparison, which can lead to lower self-
esteem. [br] 【S3】

选项

答案 cross一across

解析介词错误。本句意为“宾夕法尼亚大学的研究人员通过脸谱网、照片墙和阅后即焚这三个平台对参与者的社交媒体使用情况进行了为期一周的监控……”。分析句子结构可知，本句谓语是monitored，而句中多了一个动词cross。根据句意可知，此处意为“遍及三个平台”，故应将动词cross改为介词across，意为“遍及”。
