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.

    It started as a special day for Wesley Autrey, a 50-year-old construction worker in New York City. It was about 12:45 P.M., and he was waiting on a subway platform (月台) to take his daughters home before he went to work. He suddenly noticed a man nearby have convulsions (抽搐) and fall down suddenly. Mr. Autrey and two women went to help the stranger. The man, Cameron Hollopeter, managed to get to his feet, but then stumbled (绊倒) at the edge of the platform and fell onto the subway tracks. Mr. Autrey looked up and saw the lights of the subway train coming near through the tunnel.

    Mr. Autrey jumped onto the track immediately. He realized that he didn't have time to get Mr. Hollopeter and himself back up on the platform before the train arrived, so he lay on top of the man and pressed down as hard as he could. Although the driver tried to stop the train before it reached them, he couldn't. Five cars passed over them before the train finally stopped. The cars had passed only inches from his head.

    New York loves a hero. Mr. Autrey became an overnight hero and was named the “Subway Superman”. New York City Mayor Michael Bloomberg gave him the Bronze Medallion, the city's highest honor. He was asked to appear on several TV talk shows. He was also rewarded with money and gifts, such as $10,000 from Donald Trump, a $5,000 gift card from the Gap clothing store, a new Jeep, and Beyonce concert tickets.

    How did Autrey react (反应) to all this? He said, “I don't feel like I did anything great; I just saw someone who needed help. I did what I felt was right”.

    Most dictionaries will tell you a number of things about a language. There are three important things. These three things are spelling, pronunciation(发音) and meaning.

    First, a dictionary will tell you the spelling of a word. If you are not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in an alphabetical (字母表的) order —— a, b, c and so on. For example, on a dictionary page the "poor" comes before "poverty" and the word "poverty" comes before the "power".

    The words are always given in alphabetical order. The second thing, a dictionary will tell you the pronunciation. Most dictionaries give phonetic, or sound alphabet. The phonetic alphabet (音标) shows pronunciation. The third thing, a dictionary will tell you the meaning of words. You can look up a word and find out what it means. Many words have more than one meaning, and a good dictionary will tell you all of the word's meanings. For example, in English the common word "get" has over 20 different meanings.

    The first newspapers were written by hand and put up on walls in public places. The earliest daily newspaper was started in Rome in 59 BC. In the 700's the world's first printed newspaper was published. Europe didn't have a regularly published newspaper until 1609, when one was started in Germany.

    The first regularly published newspaper in the English language was printed in Amsterdam in 1620. In 1621, an English newspaper was started in London and was published once a week. The first daily English newspaper was The Daily Courant (《每日新闻》). It came out in March, 1702.

    In 1690, Benjamin Harris printed the first American newspaper in Boston. But not long after it was first published, the government stopped the paper. In 1704, John Campbell started The Boston Newsletter (《波士顿新闻通讯》), the first newspaper published in the American colonies. By 1760, the colonies had more than thirty daily newspapers. There are now about 1,800 daily papers in the United States.

    Today, as a group, English language newspapers have the largest circulation (发行量) in the world. But the largest circulation for a newspaper is that of the Japanese newspaper Asahi Dhimbun (《朝日新闻》). It sells more than 11 million copies every day.

    I'd just got in a taxi at the railway station when suddenly I found one of my suitcases missing. Just then, I saw a young fellow about 30 walking away with it, opening it and drawing out the valuables. "Stop thief! Stop thief!" I shouted and threw open the car door and rushed out to him, followed by the driver and half a dozen passers-by. Very soon the thief was cornered at the turn of the road. My driver caught the thief by the neck and put his hand into his trouser pocket, drawing out money, credit card, telephone book and so on and put them back into my suitcase.

    Half an hour later, the car was running at full speed on the express highway. I sat back and breathed a long sigh of relief (松口气). But as I pulled out those stolen things from the suitcase and started to check them, I became dumbfounded (惊呆了). Before my eyes were 200 yuan instead of 100. And a blood test report of a 58-year-old woman appeared. I suddenly realized that the taxi driver must have mistaken the thief's belongs and put his into my suitcase. The pitiful and begging look of the poor young man flashed across my mind again. My heart began to sink.

    Two years has passed since then. But this event keeps coming back to me. Was the young man a habitual robber or a dutiful son who had been driven to desperation (铤而走险) to find money to save his mother's life? My heart aches for him. How I wish I had gone back that summer afternoon to return the 200 yuan and say sorry to him. For the first time in my life, I realized that hate and love are very close.

    Social media (社交媒体)is one of the fastest-growing industries in today's world. A study conducted by the US think tank (智囊团) Pew Research Center showed that 92 percent of teenagers go online daily.

    The wide spread of social media has changed nearly all parts of teenagers' lives.

    ●Changing relationships

    High school student Elly Cooper from Illinois said social media often reduces face-to-face communication.

    "It makes in-person relationships harder because people give attention to their phones instead of their boyfriends or girlfriends," Cooper said.

    There's also a greater possibility of things getting lost in translation over social media.

    "If half of your relationship is over social media, you don't really know how the other person is reacting," Sienna Schulte, a junior student from Illinois, said.

    Yet, some people believe social media has made it easier to start relationships with anyone from anywhere. Beth Kaplan from Illinois met her long-distance friend through social media. He currently lives in Scotland, but they're still able to frequently communicate with one another.

    "I can feel close to someone that I'm talking to via (通过) FaceTime," Kaplan said.

    ●Wanting to be "liked"

    The rise of social media has changed the way teenagers see themselves.

    The 19-year-old Essena O'Neill announced on the social networking service Instagram that she was quitting social media because it made her obsessed (痴迷) with appearing perfect online.

    Negative comments also can do great damage to a teenager's self-esteem (自尊).

    In particular, anonymous (匿名的) social media apps such as Yik Yak may provide opportunities for cyberbullying (网络欺凌).

    The app allows users within 5 miles (8 km) to create and add comments to everything. Teenagers who get negative comments on these sites can't help but feel hurt.

    ●Opening new doors

    However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site YouTube.

    "Social media can help people show themselves and their talents to the world in a way that was never possible before," Korsos said.

    But Korsos recognizes that social media has become a distraction.

    "Social media, though it helps people connect with their friends and stay updated, is not all necessary."
