"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．

A. Hiking out with friends．
B. Making comparison with others．

4.Which can be the best title of the passage？
A. A Study on Social Media．

Recently， a 1935 letter in which Ernest Hemingway detailed his catch of a 500lb blue marlin（青枪鱼）， an adventure that is believed to have partly inspired his novel The Old Man and the Sea， has been sold for﹩28，000 （£22，000）．
The handwritten letter was sent by Hemingway on 8 May to the fishing editor of the Miami Herald， laying out in great detail how the author and his friend Henry Strater battled to keep sharks away from the marlin after catching it off the Bahamian island of Bimini．
Nate D Sanders， the auction（拍卖） company which sold the letter， said it documented for the first time in Hemingway's own words not only the size of the marlin， but also the attack by sharks， reflecting the plot of the novel．
The company added that Hemingway's account of the marlin catch differed from other anecdotes of it， one of which described Hemingway using a machine gun on the sharks， which is said to have attracted more sharks rather than frightened them away．
The Old Man and the Sea was also inspired by an anecdote told by Hemingway's Cuban friend Carlos Gutierrez． In 1936， Hemingway wrote in a magazine that Carlos had told him about an old fisherman who caught a great marlin alone．
Three years later， Hemingway told his editor Max Perkins that he was planning a short story about the old commercial fisherman who fought the swordfish all alone in his sailing boat． Instead， he ended up writing For Whom the Bell Tolls， not returning to the story about the old fisherman until January 1951． It won him the Pulitzer in 1953， and was specifically cited when he was awarded the Nobel Prize in 1954．
1.What does the underlined phrase "laying out" in the second paragraph mean？
A. Discussing．
B. Wondering．
C. Imagining．
D. Presenting．
2.What did the auction company stress when selling the 1935letter？
A. The style of the writer．
B. The history of the letter．
C. The contents of the letter．
D. The popularity of the writer．
3.What inspired Hemingway to write The Old Man and The Sea besides his own adventure？
A. Henry Strater's account．
B. Carlos Gutierrez's story．
C. Max Perkins' life experience．
D. Nate D Sanders' description．
4.Which is the correct order of time for the following facts in the passage？
1Hemingway wrote a letter to describe his adventure．
2Hemingway caught a big blue marlin．
3The letter was sold at auction．
4The Old Man and The Sea won the Nobel Prize．

Last month our class organized a hiking along the Chaobai River，which run through Hebei， Beijing and Tianjin． Much to my disappoint， I found the river was serious polluted． At that moment， I was determined to do what I could protect it． First， under my teacher's help， I used the equipments from the school lab to test the quality of the river water． But then，I used the data I had collected it to analyze the pollution of the water． Finally，I write a report on the pollution of the river to the local government． I also gave a presentation in class where I suggested that we must make small changes to protect our water resources．
