Nowadays, we can read almost all “truths” on social media sites. But are they really reliable? Sites such as the micro messaging service Twitter, the social networking site Facebook and the photo-sharing app Instagram might “misrepresent the real world,” according to a study by computer scientists from McGill University and Carnegie Mellon University.
The scientists warn that gathering information about public views and trends from these sites is unwise. There are still large parts of the population who do not take part in social media activities. Also, there's a risk that many social media users are under- represented. Instagram, for example, appeals to younger adults in urban areas while Pinterest is used mainly by females aged 25 to 34. And only 5 percent of Twitter users are over 65 years old, according Io the study.
However, this is not the only issue, according to the scientific team. The design of a website can influence how people behave online, creating what the researchers call “Internet bias.” For example, micro-blogging sites such as Weibo promote “popular” stories. It saves time for some, but it also limits readers' choice of what they see. In the end, many people open those stories and make them more “popular.” But it's not because they choose those stories. Rather, it is because the content is right in front of them.
Besides, it's possible that not everyone on your social networks is real. There might actually be a few fake accounts among them. Fake “bots” pretend to be human and are often included when measuring or predicting human behaviors online.
The findings might be more important than you would think, since many social media studies “are used to inform and justify decisions and investments among the public and in industry and government,” said Derek Ruths, assistant Professor at McGill's School of Computer Science.
If the team is right, you might have to think carefully the next time you say, “It's true, you know; I read it on Weibo.”

阅读下列短文，从每题所给的A、B、C、D 四个选项中，选出最佳选项.
By now, we are all aware that social media has had a tremendous influence on our culture, in
business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends’ new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?
Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.
Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.
Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.
Also, what you carelessly post on the Net can come back to trouble you. Revealing( 泄露) personal information on social sites can make users vulnerable(易受伤害的)to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.
Social media has its advantages and drawbacks as each coin has two sides. It is up to each user
to use social sites wisely to enhance their professional and social life, and exercise caution to ensure
they do not fall victim to online dangers.

Almost all of us heard the story “Here Comes the Wolf” when we are little kids. What we can learn from the story is we must be honest. Therefore, there’re lots of phenomenon of dishonesty nowadays.
Being honest does great harm not only to other people and also to yourself. Take the case of fake milk powder for an example. After drinking this kind of milk, the baby had big heads while their legs and arms were still thin, what badly affected their health. To my great relief, the producers got accused and punished net all the serious consequences in the end.

Videos and video calls are becoming increasingly popular on social media in China, particularly on WeChat, the country’s most-used messaging app. We Chat’s 1.08 billion monthly active users last year made 410 million daily video and audio calls. That was 5.7 times more than in 2015, when WeChat first disclosed its operational data.
Uploading videos on WeChat Moments, a function that allows users to share their latest whereabouts, has become more widely used, with the number of videos posted multiplying 4.8 times in the past 4 years.
As a one-stop solution for Chinese people’s daily lives, We Chat has been able to produce a breakdown of its users’ preferences by age group. Those born in the 1980s for example are followers of news related to state and public affairs, whereas those younger than 20 spend the most on sweet treats.

As of September 2018, over 63 million users were registered as 55 years old or above. This group recorded an average length of 11 minutes for video calls, topping all age groups. We Chat Wallet has also registered exponential (指数的) growth, with payments in public transportation and high-speed traffic rising 4.7 times and 6.3 times, separately. Spending in retail stores and dining via WeChat rose by 1.5 times and 1.7 times. The number of users who use the app for making medical appointments and paying bills almost tripled.

Students today have an important and wonderful advantage: social media. However, we should know that not all social media platforms are created equal.
Twitter
Advantage: Twitter is best for conducting quick surveys and advertising. Twitter is also great for keeping up with current events. By following active politicians, we are becoming more familiar with their policies and their faces. Twitter is also better for online debates because of the character limit.
Disadvantage: Twitter’s disadvantage is that you can see so many things you’re not interested in because the people you follow retweet these posts.
Facebook
Advantage: Its best uses are keeping up with family and high school friends. Also Facebook makes it extremely easy to inform students about concerts and fairs. It’s the only big social media platform—where you can create specific albums for different things.
Disadvantage: Facebook’s biggest downfall is that if you comment on anything, you get notifications for every other comment. Additionally, debates about everything under the sun.
Snapchat
Advantage: The best social media platform for socializing is actually Snapchat. Snapchat works quickly and gives you the freedom to be spontaneous (常心血来潮的) with your posts. It gives you the most insight into the people you follow or are friends with. In high school, my friends would always tell me, You’d probably know more about our lives if you were on Snapchat.
Disadvantage: On Snapchat, stories disappear alter 24 hours and you can miss some great moment if you don’t check it regularly.
Instagram
Advantage: It’s like an online diary of our best moments. For many of us, posting on Instagram is like the college version of show-and-tell.
Disadvantage: It has too many advertisements. Many times when you just want to see what your friends have recently posted, the app throws in an advertisement that looks like any other post.
1.Why is Twitter considered annoying?
A.It always has various repetitive contents.
B.It almost focuses too much on politicians.
C.It seldom keeps up with current events.
D.It often asks users to do quick surveys.
2.What is Facebook suitable for?
A.Making contents. B.Doing quick surveys.
C.Running advertisements. D.Producing different albums.
3.In which platform will you probably miss some posts after a day?
A.Twitter. B.Facebook.
C.Snapchat. D.Instagram.

British chemist David Evans has become an overnight celebrity on Chinese social media. His chemistry experiments have attracted over 2 million followers in just a few months. Evans is a chemistry professor at the Beijing University of Chemical Technology. The 60-year-old always wears a white lab coat, a pair of safety goggles (护目镜), and smiles often. Some web users say he looks just like the “grandpa of KFC”.
Evans has posted videos of various experiments. His most popular experiments have attracted millions of hits on video-sharing apps. Excited children’s cheers and shouts can be heard in his videos. “I hope my experiments can arouse people’s interest in science,” he says.
Evans has been interested in China since childhood. In the early 1970s, before the reform and opening-up, he viewed it as a “country full of mysteries”. He first visited the Chinese mainland in 1987 to attend a chemistry conference in Nanjing, Jiangsu Province. He quit his job in the United Kingdom and moved to Beijing in 1996. Many of his friends thought he was crazy. But Evans says they just saw China’s challenges but not its potential.
Since 2011, Evans has turned to the Internet to popularize science. He learned short-video apps are also popular in small cities and rural areas. And he realized this enables him to reach more students, who lack opportunities to perform fun experiments. But even a one-minute video requires a considerable amount of work. Still, he thinks it’s worth it to fulfill his responsibility to popularize science.
His experiments always fill schools’ lecture halls with laughter. Some viewers call him “a Harry Potter-like magician”, but he disagrees. “A magician never tells the secrets behind his tricks, but a scientist always gives an explanation.” He sees himself as a teacher. He performs experiments to spread knowledge, inspire thinking, remove misunderstandings and show that science can create change. Evans says he looks forward to more “chemical reactions” with China.
1.Who is David Evans according to the passage?
A. A manager of KFC. B. A film celebrity.

Keeping your teenager out of the social media world is impossible. Whether we like it or not, our kids are growing up in a digital era- -and although that creates major opportunities, it also comes with some pretty big risks. We saw this firsthand when we asked a group of tweens and teens to give up their phones and social media for a week; it was as though we’d asked them to part with a limb.
A recent study of more than 10 ,000 six- to twelve-grade girls carried out by a nonprofit organization Ruling Our Experiences found that high school girls spend an average of six hours a day on social media. And the effect of too much logged-on time is clear. The study found kids who spend eight hours or more on technology per day are five times more likely to be sad or depressed. Adding to the pressure is that2 out of 3 high school girls report being asked to send a revealing photo to another person, and most of them report that they do send sexual texts and photos to each other.
Another study, carried out by Common Sense Media, found that girls use social media more than boys and are also more likely to experience negative consequences. Most of the girls investigated admitted that content posted online often makes them worry about their appearance or social status, while just a quarter of the boys said the same. An earlier study from the Pew Research Center’s Internet came to a similar conclusion: A third of 12- to 13-year-old girls who used social media believed their peers were mostly unkind to each other online , while only 9 percent of the boys agreed.
Of course, these differences don' t mean we shouldn’t have concerns about boys and the impact of digital overload or online bulling. In fact, other studies have shown that boys and girls can be equally damaged by social media. The most important thing is for teens to feel safe, online and in the real world alike.
1.What is the second paragraph mainly about?
A.The pressure of the high school girls logging-on.
B.The influence of too much logged-on time on high school girls.
C.Too much time spent on social media for high school girls.
D.The increasing population of the high school girls logging-on.
2.Which of the following can replace the underlined word “revealing” in paragraph 2?
A.Exposed. B.Interesting.
C.Funny. D.Romantic.
3.Why are the girls more likely to experience negative effect online than boys?
A.Because the girls' social status is low.
B.Because the girls are mostly unkind to each other.
C.Because the girls use social media more than boys.
D.Because the girls pay more attention to their appearance.
4.What can be inferred from the passage?
A.Parents should keep teens out of the social media.
B.Parents keep teens feel safe online and in the real life.
C.It is time to worry about your teens and social media.
D.Boys and girls can be equally damaged by social media.

Hollywood’s only Chinese-American superhero has stirred up heated debate on social media after she spoke out against discrimination in American show business.
Chloe Bennet, a Chinese-American actress who stars in Marvel’s trending TV series Agents of S.H.I.E.L.D., explained on social media why she changed her last name from Wong to Bennet, arguing that Hollywood is “racist” and wouldn’t cast her with a last name that made them “uncomfortable.”
“Changing my last name doesn’t change the fact that my BLOOD is half Chinese, that I lived in China, speak Mandarin, or that I was culturally raised both American and Chinese,” replied Bennet.
Bennet’s remarks come after Ed Skrein stepped down from his role as Major Ben Daimion in the upcoming Hellboy movie for fear that his participation would be “whitewashing” a character of Asian descent(后裔).
Racial barriers have been an essential problem in Hollywood. According to research conducted by the University of Southern California in 2015, nearly three-quarters of all characters in the top 100 films of 2014 were white, while only 5.3 percent of Asian artists can share the same privilege. In another report released in 2017, only 3.4 percent of over 1,000 surveyed films had an Asian director.
“Asian artists can hardly stand out in Hollywood. Most roles starred by Asians are fixed and stereotyped, as if all Asians are good at math and martial arts. There is an invisible discrimination lurking(潜伏) in show business, as the difference of your skin color may bring disparity in your income and opportunities,” said Alex She, a New York-based Chinese-American photographer and movie maker.
Bennet’s experience has led to heated debate on both Chinese and foreign social media.
1.What’s the best title of the passage?
A. Racial discrimination worsens in Hollywood
B. Chinese-American actress voices for equal rights in Hollywood
C. Chinese-American actress changed her name
D. Chinese-American actress makes a fame in Hollywood
2.Why did Chloe Bennets change her last name?
A. Because she doesn’t like it
B. Because her parents suggested it
C. Because using an English name is a trend in Hollywood
D. Because the racism in Hollywood’s show business made her no choice
3.Which of the following words can best describe Chloe Bennet?
A. brave and courageous B. selfish and cocky
C. stubborn and aggressive D. overcautious and timid
4.What may be discussed next according to the passage?
A. Netizens’ support to Bennet’s works
B. Netizens’ opinion on Bennet’s experience
C. Bennet’s achievement in Hollywood
D. Bennet’s family background
