There was a survey of the people who were born from 1980 to 2000， asking them what their most important life goals were． Over 80 percent said it was to get rich． 1. We're constantly told to devote more to our work， to push harder and to achieve more． We're given the impression that these are the things that we need to go after to have a good life． But is that the truth？ 2.
But what if we could study people from the time when they were teenagers all the way into old age to see what really keeps people happy and healthy？ The Harvard Study of Adult Development did it． For 75 years， they've tracked the lives of 724 men． Studies like this are extremely rare． Almost all projects of this kind fall apart within a decade because too many people drop out of the study．3. Or the researchers can't get together． But through a combination of luck and the persistence of several generations of researchers， this study has survived．
So what have they learned？ The conclusion is that it's not wealth or fame that counts．
4. They've learned three big lessons about relationships． Firstly， people who are more socially connected to family， to friends and to community are happier and physically healthier． The second is that it's not just the number of friends you have but the quality of your close relationships that matters． And the third is that good relationships don't just protect our bodies．5.
A． They can even protect our brains．
B． To become famous came second．
C． Or funding for the research dries up．
D． The good life is built with relationships．
E． It turns out that being in conflict is bad for our health．
F． It is good relationships that keep us happier and healthier．
G． To be frank， sometimes wealth and fame can make people happy．
"Big tobacco" is what the bosses of several large technology firms have started calling Facebook． Being compared to the tobacco giants is far from praise， but it is not the only wide﹣spread analogy（比拟）． A lower blow is the suggestion that Facebook may become like Yahoo， the once high﹣flying internet firm that fell．
Even a year ago the idea would have been unthinkable． But since January Facebook has become trapped in a series of misjudgments and missteps． It became clear that it had done too little to stop Russian interference（干涉） in America's election in 2016． It had to admit that it had shared the personal data of 90m users with outside firms without permission．
The comparison to Yahoo is imperfect． Even at its peak Yahoo's business was never as large and profitable as Facebook's． One of the main reasons Yahoo declined is because it lost out to a powerful competitor， Google， in online search； Marissa Mayer， its boss from 2012 until its sale to Verizon last year， was unable to restore advertisers' or employees' confidence as users left．
But people who watched Yahoo's falling see similarities． Executive（主管） turnover was a leading indicator of its decline； before Ms． Mayer was hired Yahoo went through four chief executives in three years． Mr． Zuckerberg， who controls the majority of Facebook's voting shares， is not leaving， but many top executives are． This year several have announced their departures， including Facebook's chief security officer．
When advertisers' faith in Facebook has been shaken， politicians in Washington are running out of patience with the company． Lawmakers' inspection of the firm is causing it to be more cautious about how it uses data for targeting advertisements and about what information it makes available to outsiders．
Mr． Zuckerberg and Ms． Sandberg are under pressure to prove to employees and advertisers that Facebook is not only trustworthy but worthy of their time and money． If they cannot do so， and the company's share price continues its slide， it is possible that Ms． Sandberg will be replaced in the next year． Mr． Zuckerberg will doubtless have thoughts about Yahoo's sorry tale．

University of Pennsylvania researchers say that for the first time they have linked social media use to increases in depression and loneliness． The idea that social media is anything but social when it comes to mental health has been talked about for years， but not many studies have managed to actually link the two． To do that， Penn researchers， led by psychologist Melissa Hunt， designed a study that focused on WeChat， Snapchat and Instagram．
The study was conducted with 143 participants， who before they began， completed a mood survey and sent along photos of their battery screens， showing how often they were using their phones to access social media． "We set out to do a much more complete study which attempts to imitate real life．" Hunt said．
The study divided the participants into two groups： The first group was allowed to maintain their normal social media habits． The other， the control group， was restricted to 10 minutes per day on social media． The restrictions were put in place for three weeks and then the participants returned and were tested for outcomes such as fear of missing out， anxiety， depression and loneliness．
The results showed a very clear link between social media use and increased levels of depression and loneliness． "Using less social media than you normally do would lead to significant decreases in both depression and loneliness，" Hunt said．
Social media invites what Hunt calls "downward social comparison．" "When you're online， it can sometimes seem that everyone else is cooler and having more fun and included in more things and you're left out，" Hunt said． And that's just generally discouraging． "Every minute you spend online is a minute you are not doing your work or not meeting a friend for dinner or having a deep conversation with your roommate．" And these real life activities are the ones that can encourage self﹣esteem and self﹣worth， Hunt added．
"People are on their devices， and that's not going to change，" she said． But as in life， a bit of control goes a long way．
1.Before the study was conducted， the participants completed a survey to ．
A. imitate people's real life
B. link loneliness to depression
C. show their use of social media
D. prove social media is important
2.The results of the study showed using less social media would result in ．
A. people's fear of missing out
B. higher levels of depression
C. obvious relief in loneliness
D. lower levels of happiness
3.In Hunt's opinion， which activity benefits more to mental health？
A. Hiking out with friends．
B. Making comparison with others．
C. Playing computer games in spare time．
D. Logging onto social media and having fun．
4.Which can be the best title of the passage？
A. A Study on Social Media．
B. How to Improve Mental Health．
C. People Addicted to Social Media．
D. Social Media Influences Mental Health．
