    A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.

    Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived(感知到的)social isolation than those who said they spent a half-hour per day or less on the same sites.

    According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader's Digest. “Although people think being on social media all the time makes them 'connected' to others, they are actually 'disconnected,' because the more time one spends behind a screen, the less time one spend face-to-face.”

    “Part of the issue of loneliness is that the majority of people who use social media aren't just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else's posts, where they are and what they are doing. The constant exposure to everyone else's 'perfect' life experiences causes feelings of being left out.”

    So what's the answer? It's simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else's life. Just focus on your own life, where you're going, what you are grateful for, and what you want to accomplish in this world.”

阅读下面文言文,完成下列小题。

谏说之难洪迈

    韩非作《说难》,而死于说难,盖谏说之难,自古以然。至于知其所欲说,迎而拒之,然卒至于言听而计从者,又为难而可喜者也。

    秦穆公执晋侯,晋阴饴甥往会盟,其为晋游说无可疑者。秦伯曰:“晋国和乎?”对曰:“不和。小人曰必报仇,君子曰必报德。秦伯曰:“国谓君何?”曰:“小人谓之不免,君子以为必归;以德为怨,秦不然。”秦遂归晋侯。

    秦伐赵,赵求救于齐,齐欲长安君为质。太后不肯,曰:“复言者,老妇必唾其面。”左师触龙愿见,后盛气而揖之入,知其必用此事来也。左师徐坐,问后体所苦,继乞以少子补黑衣之缺。后曰:“丈夫亦爱怜少子乎?”曰:“甚于妇人。”然后及其女燕后乃极论赵王三世之子孙无功而为侯者祸及其身后既寤则言长安君何以自托于赵?于是后曰:“恣君之所使。”长安君遂出质。

    范雎见疏于秦,蔡泽入秦,使人宣言感怒雎,曰:“燕客蔡泽,天下辩士也。彼一见秦王,必夺君位。”雎曰:“百家之说,吾既知之,众口之辩,事皆摧之,是恶能夺我位乎?”使人召泽,谓之曰:“子宣言欲代我相,有之乎?”对曰:“然。”即引商君、吴起、大夫种之事。雎知泽欲困己以说,谬曰:“杀身成名,何为不可?”泽以身名俱全之说诱之,极之以闳夭、周公之忠圣。今秦王不倍功臣,不若秦孝公、楚越王,雎之功不若三子,劝其归相印以让贤。雎竦然失其宿怒,忘其故辩,敬受命,延入为上客。卒之代为奏相者泽也。

    秦始皇迁其母,下令曰:“敢以太后事谏者杀之。”死者二十七人矣。茅焦请谏,王召镬将烹之。焦数以桀、纣狂悖之行,言未绝口,王母子如初。

    吕甥之言出于义,左师之计伸于爱,蔡泽之说激于理,若茅焦者真所谓剧虎牙者矣。范雎亲困穰侯而夺其位,何遽不如泽哉丨彼此一时也。
