1 . You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community (社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

If it weren’t for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness(意识) of the dangers of pollution and the harmful effects of chemicals on humans and on the world’s lakes and oceans.

When Sandra Day O’Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and in 1981, the first woman to join the U. S. Supreme Court (最高法院). O’Connor gave the deciding vote in many important cases during her 24 years on the top court.

On December 1,1955, in Montgomery, Alabama, Rasa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott (抵制). It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was, was tired of giving in,” said Parks.

3 . Although problems are a part of our lives, it certainly doesn't mean that we let them rule our lives forever. One day or another, you'll have to stand up and say—problems, I don't want you in my life.

    1    Problems with friends, parents, girlfriends, husbands, and children—the list goes on. Apart from these, the inner conflicts within ourselves work, too. These keep adding to our problems. Problems come in different shaped and colors and feelings.

But good news is that all problems can be dealt with. Now read on to know how to solve your problems.

Talk, it really helps. What most of us think is that our problem can be understood only by us and that no talking is going to help.     2    Talking helps you move on and let go.

Write your problems.     3    When you write down your problems, you are setting free all the tension from your system. You can try throwing away the paper on which you wrote your problems. By doing this, imagine yourself throwing away the problems from your life.

Don't lose faith and hope. No matter what you lose in life, don't lose faith and hope. Even if you lose all your money, family…you should still have faith.     4    

Your problems aren't the worst. No matter what problem you get in life, there are another one million people whose problems are huger than yours.     5    Your problems might just seem big and worse, but in reality they can be removed.

Go about and solve your problems because every problem, however big or small, always has a way out.

6 . Money with no strings attached. It’s not something you see every day. But at Union Station in Los Angeles last month, a board went up with dollar bills attached to it with pins and a sign that read, “Give What You Can. Take What You Need.”

People quickly caught on. And while many took dollars, many others pinned their own cash to the board. “People of all ages, races, and socio-economic(社会经济的) backgrounds gave and took,” said Tyler Bridges of The Toolbox, which created the project. “We even had a bride in her wedding dress come up to the board and take a few dollars.” Most of the bills on the board were singles, but a few people left fives, tens and even twenties. The video clip(片段) shows one man who had found a $ 20 bill pinning it to the board.

“What I can say for the folks that gave the most, is that they were full of smiles,” Bridges said. “There’s a certain feeling that giving can do for you and that was apparent in those that gave the most.” Most people who took dollars took only a few, but Bridges said a very small number took as much as they could.

While the clip might look like part of a new ad campaign, Bridges said the only goal was to show generosity(慷慨) and sympathy. He added that he hopes people in other cities might try similar projects and post their own videos on the Internet.

“After all, everyone has bad days and good days,” he said. “Some days you need a helping hand and some days you can be the one giving the helping hand.”

8 . Nowadays, we can read almost all "truths" on social media sites. But are they really reliable? Sites such as the micro-messaging service, the social networking site 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 the micro-messaging service users are over 65 years old, according to 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 humans 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, according to Derek Ruths, an assistant professor of Computer Science at Mc Gill University.

If the team is right, you might have to think carefully next time you say, "It's true, you know; I read it on Weibo."

9 . For several months, Cara has been working up the courage to approach her mom about what she saw on Instagram. Not long ago, the 11-year-old girl, like all the other kids in this story, discovered that her mom had been posting her photos for much of her life.“I’ve wanted to bring it up.It’s strange to see myself up there, and sometimes there are pictures of myself I don't like,”she said.

Like most other modern kids, Cara grew up in social media. While many kids may not yet have accounts themselves, their parents, schools, sports teams, and other organizations have been organizing online presence for them since birth.The shock of realizing that details about your life have been shared online without your permission or knowledge has become an important experience in the lives of many teenagers. Recently a parenting blogger (博主) wrote in an essay of The Washington Post that despite (尽管)her 14-year-old daughter’s horror of discovering that her mother had shared years of highly personal stories and information about her online, she simply could not stop posting them on her blog and social media. The writer said that promising her daughter that she would stop posting things about her publicly on the Internet “would mean shutting down an important part of myself, which isn't necessarily good for me or her”.

But it’s not just crazy mommy bloggers who construct their children’s online identity; plenty of average parents do the same. There’s even a special word for it: sharenting (晒娃成癖). Almost a quarter of children begin their digital lives when parents upload their photos to the Internet, according to a study conducted by the Internet-security (安全)firm AVG. The study also found that 92 percent of kids under the age of 2 already have their own unique digital identity.

10 . Every week in China, millions of people will sit in front of their TVs watching teenagers compete for the title Character Hero, which is a Chinese-style spelling bee. In this challenge, young competitors must write Chinese characters by hand. To prepare for the competition, the competitors usually spend months studying dictionaries.

Perhaps the show’s popularity should not be a surprise. Along with gunpowder and paper, many Chinese people consider the creation of Chinese calligraphy(书法) to be one of their primary contributions to civilization. Unfortunately, all over the country, Chinese people are forgetting how to write their own language without computerized help. Software on smart phones and computers allows users to type in the basic sound of the word using the Latin alphabet. The correct character is chosen from a list. The result? It’s possible to recognize characters without remembering how to write them.

But there’s still hope for the paint brush. China’s Education Ministry wants children to spend more time learning how to write.

In one Beijing primary school we visited, students practice calligraphy every day inside a specially decorated classroom with traditional Chinese paintings hanging on the walls. Soft music plays as a group of six-year-olds dip brush pens into black ink. They look up at the blackboard often to study their teacher’s examples before carefully attempting to reproduce those characters on thin rice paper. “If adults can survive without using handwriting, why bother to teach it now?” we ask the calligraphy teacher, Shen Bin. “The ability to write characters is part of Chinese tradition and culture,” she reasons. “Students must learn now so they don’t forget when they grow up.” says the teacher.
