China, org. cn selected its top 10 people who moved China in 2012. These heroes included a jet engineer, a businessman, a teacher, as well as nurses and migrant workers. Here are the accounts of the exemplary deeds of Zhang Lili, a teacher. Zhang Lili is a teacher at the No. 19 Middle School in Jiamusi, Heilongjiang Province. She suffered from serious injuries after saving two students from being hit by an oncoming bus on May 8.

    Zhang and her students were crossing the road just outside the school gate when suddenly a runaway school bus changed direction towards the students. Zhang managed to push both students out of the vehicle's destructive (破坏的，毁灭性的）path, but she herself did get run over. Her legs were crushed and later had to be cut off above the knee.

    Bom on Jan. 19, 1984，in Jiamusi, Zhang was a 168cm-tall lively and cheerful young woman who had devoted herself entirely to her job. She got married in 2009. The couple planned on having a baby after the graduation of her class.

    Zhang's act of heroism has moved a large number of people. She was even named “the most beautiful teacher” by netizens. She was awarded the “May I Labor Medal” and given the title of “Female Pace-setter” by authorities. She became a Party member in July.

    Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.

    No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.

    There is more good news for people, if they have friends. These people live longer than those who don't have friends. Why? It could be that they are happier. Being happy helps them keep Healthy. Or it could be just knowing that someone cares. If someone cares, they take better care of themselves.

    In China we can see more African students in universities, which is a signal of a deeper China-Africa relationship, and the same trend is happening in Africa as well. Most Chinese students choose to study in universities in South Sudan, Egypt, Kenya, Ghana, Ethiopia and South Africa.

    There are three types of Chinese students in Africa. One type is language students who major in local African languages such as Swahili in China and go to African countries to study the language. Another type is non-language students who major in law, economy, culture, education or agriculture and go to African universities for six months to a year to learn more about the culture or for research. The above two types of students are all funded by Chinese government.

    A third type has been growing in recent years. More Chinese choose to develop their career and build a life in African countries, and some of their children tend to receive higher education in African countries. Some Chinese who work in Africa also further their study in their free time. Many Chinese choose to join the MBA program, since they work in a Chinese state-owned enterprise, and an MBA degree could help advance their career.

    In addition, as China and Africa's relations and cooperation are heating up and more Chinese companies and investors come to Africa under The Belt and Road Initiative(一带一路), more talents that understand Africa are needed. Besides, the new generations have more internationalized, curious attitudes, and are more willing to see and experience Africa themselves without any stereotypes(刻板印象), rather than just reading about it in a textbook.

    Last year, I lived in Chile for half a year. I lived with a Chilean family and had the responsibilities of any Chilean teenager. I had good days and bad days I didn't understand.

    Chuquicamata, my host community, is a mining camp. When I arrived there, I was scared. It was so different from what I was used to. There were lots of dogs on the streets, and there was no downtown, few smoothly paved streets, and little to do for entertainment. Rain was not seen very often, earthquakes and windstorms were frequent.

    I had studied Spanish for two and a half years and was always one of the best students in my class. But in my first week in Chile I was only able to communicate and needed one person to whom I could explain my shock. I couldn't speak the thoughts in my head and there were so many.

    Most exchange students experience this like me. Culture shock presents itself in everything from increased aggression towards the people to lack of appetite (食欲). I was required to overcome all difficulties.

    As time passed, everything changed. I began to forget the words in English and to dream in Spanish and love Chilean food. I got used to not depending on expensive things for fun. Fun in Chuquicamata was being with people. And I took math, physics, chemistry, biology, Spanish, art, and philosophy.

    But the sacrifices were nothing compared to the gain. I learned how to accept and to succeed in another culture. I now have a deeper understanding of both myself and others.

    The Secretary-General of the U.N. has always been chosen in private meetings. But for the first time in its 70-year history, part of the selection process is taking place in public.

    At least eight countries have announced their candidates (候选人) for the position, among whom are women, including Irina Bukova from Bulgaria, Susana Malcorra from Argentina and Helen Clark from New Zealand. 56 countries says the next U.N. chief should be a woman. There have been eight U.N. chiefs, none of whom was a woman.

    All member states were permitted to ask the candidates questions during two hour-long meetings last week in the U.N. General Assembly (联合国大会). The candidates were also asked some of the 1,000 questions written by people on social media.

    They were asked questions about development, how they would improve efforts to create peace and how they would protect human rights.

    The U.N. Security Council will examine the candidates' backgrounds. Then the 15 members will vote secretly until one person is chosen. The General Assembly will then vote on whether to accept the choice.

    Britain, China, France, Russia and the United States are the five permanent members of the Security Council. Experts say they are likely to have more influence on who will be the new secretary-general than the 10 non-permanent nations on the council.

    The Security Council will begin to discuss who will be named the next secretary-general in July. A new secretary-general may not be confirmed until as late as November.

    The U.N. has a tradition of choosing its new leader from a part of the world different from its current leader. U.N. Secretary-General Ban Ki-moon is from Asia. The previous U.N. chief was Kofi Annan, who was from Africa.

    Dan Thomas is a spokesman for the president of the General Assembly. He says there is no rule that says where a new secretary-general must come from. But most observers say the new U.N. chief will not be from Asia or Africa.

    Daniella was brushing her daughter's long brown hair when she noticed that bunches of it were coming out. That was January 1, 2017. Within 20 days, seven-year-old Gianessa's hair and eyebrows were completely gone, and her doctor said they would never grow back. Gianessa had become one of the 6.8 million Americans with alopecia, a disease that causes hair loss.

    Alopecia isn't painful, but for kids who suffer from it, the acute mental pain comes from standing out from the crowd. For the most part, the students in Gianessa's first-grade class in Salem, Utah, were understanding. But occasionally, she still felt like an outcast(被排斥者). "I did not want her to not feel beautiful," her mother told Today.

    Then the school announced its "Crazy Hair Day" competition in April, and Daniella and Gianessa decided that rather than hiding Gianessa's baldness(光头), they would celebrate it. Daniella bought sticker jewels and decorated her daughter's head with colorful designs. "They just fit her personality," Daniella told CNN. "She's so full of life."

    On the morning of the competition, Gianessa was nervous. Would her friends think it was funny? She had nothing to fear. Gianessa was a hit—and the winner of the crazy-hair competition. Gianessa is now glad she dared to go bare. "I was sad at first when I lost all my hair," she told People, "but now I love being bald. I can do things to my head that other kids can't. I'm thinking now it might be fun to decorate my head with some shiny butterflies and flowers."
