    A frightening incident took place Sunday night on a plane. According to reports, the United Airlines overbooked (超额预订) the flight, so they asked passengers to give up four tickets so that four United Airline staff (工作人员) could take the seats. The airline first looked for volunteers. They offered $400 for anyone who agreed to leave the flight, then increased to $800 and a hotel stay, but no passengers would give up their seat. In the end, the airline staff used computer to select four people to be kicked off the flight.

    A 69-year-old passenger among the four unlucky passengers refused to leave and said he had to work at a hospital the next day. Three guards then showed up and pulled him out with force. The old man was badly hurt after the struggle. The flight finally left after two hours.

    The scene was recorded by other passengers and posted on the Internet. You can hear the old man shouting at the guards, saying what they were doing was wrong. Many people expressed their anger at the incident.

    The CEO of United Airlines defended the actions of the staff. In a letter he said to his staff, “Our people followed the rules for dealing with situations like this,” His response to the incident was thought as having a bad attitude. After the incident, United Airlines loses $800 million in the stock market (股市). A day and a half after the incident, United Airlines finally admitted it did something wrong. The government will survey the incident to find out whether the United Airlines had followed the rules.

    Rose is a student from the U. S. She is in Shanghai with her parents now. She doesn't know Chinese, but she is trying to study and speak it. She often tries to speak Chinese with her Chinese friends. Sometimes they don't understand her, because she can't speak Chinese well.

The boy can't understand her. Then she takes out a pen and a piece of paper. She draws flowers on it, and then gives the picture to the boy and says something about it. The boy smiles and then shows Rose the way to the park.

    Riley read so many stories about pirates (海盗) and treasure chests that he wanted to find a treasure chest of his own. One day, Riley went to the library and read a story about a man that buried expensive gold coins in his backyard in a chest. Riley was so interested in the story. "Mom, tell him that treasure chests are only in books and movies," said his old brother Ted. "It could really happen," said Riley. "Riley's right," said mom. "If you believe in something strong enough, it could happen."

    That night Riley's mom told Riley's dad how much Riley wanted to find a treasure chest. "I have an idea," said Riley's mom. "Saturday is Riley's birthday. Let's put his gift in a treasure chest and bury it in the yard for him to find." "That's a great idea!" said Riley's dad. They decided to put his new watch in the treasure chest. They would give him a map with clues (线索 ) to look for the treasure chest outside.

    After Riley left for school the next day, his mom wrapped the watch and went to the party store to buy a treasure chest. She came home and buried the treasure chest underneath the oak tree. She then drew a map with clues to where the treasure chest was buried. When Saturday came, mom and dad gave Riley his map, and told him that he would have to find his gift in the treasure chest using the clues on the map. Riley was so excited! He anxiously followed all the clues and found the treasure chest with his new watch. "Wow!" said Riley. "This is fantastic! I knew I would find a treasure chest someday!"

    "Happy Birthday!" they all shouted.

    Though very cold temperatures continued to trouble the US in January this year, an act of kindness warmed everyone. In Chicago a young man provided a homeless old man with the proper footwear—from his own feet. Jessica Bell, a passenger, saw everything and posted the story on Facebook.

    According to her Facebook post, Bell was taking the train home on Friday when she noticed a homeless old man sitting across from her. Bell wrote that the man was wearing tattered shoes, and many pairs of socks to keep his feet warm, but there was blood seeping (渗) through.

    On the same train was another man. According to Bell's description, he was young, carrying a bag and a suitcase. He was wearing big black snow boots (靴子), which looked new and expensive. They were built for a Chicago winter. Then he did a good thing.

    Bell described that the young man took off his own boots and passed them to the old man. He opened his suitcase and gave him a pair of socks as well. Then the young man put on a different pair of shoes—not as nice as the ones he had given away. He told the old man to try them on and helped him clean his feet and change into the new boots as quickly as he could, and then left the train.

    At the end of her post, Bell wrote. "I love my city. I love that in a time and place where a quiet act of kindness appears without warning." The story has received thousands of comments (评论), with many people describing how moving they found the act of kindness. One wrote, "We can all learn from that young man." Others are thanking Bell for sharing the story—there are still good people in the world.
