In the town of Swedesboro, New Jersey, 5^th grade students are determined to make 2,000 paper cranes (纸鹤) by the end of the school year. Their1is to put smiles on kids' faces.

    The idea of 2 the paper cranes started when their3 Tara Milward, read them the story Sadako and the One Thousand Paper Cranes in class. Sadako was 4with leukemia (白血病) at a very young age. She5folding the paper cranes along with her family and friends6 this was a symbol of hope for Sadako to get7one day.

    The students of Harker School wanted to8 Sadako's story. They began buying paper9 paper cranes, and decided to make 2,000! They want to send the101,000 cranes to Hiroshima, Japan where Sadako lived. The next 1,000 cranes are 11 to a local hospital. Wherever a paper crane is made, the students are12that something so simple can help someone 13 hope.

    They are so devoted to the14that they work on it in every minute of their15time to help them towards their big goal of 2,000 paper cranes. To achieve their16 goal, all of the students are coming together and working very17 They are eager to spread the hope to their friends and families, also a18of this extraordinary project.

    The students are 19 by Sadako's story and are making their impossible dream come true. They hope to make a 20 around the globe to show that everyone can make the world a better place.

    Clara Daly was sat on an Alaska Airlines flight from Boston to Los Angeles. Then a flight attendant asked an urgent question over the loudspeaker: "Does 1 on board know American Sign Language?"

    Clara, 15 at the time, 2 the call button. The flight attendant came by and explained the 3. "We have a passenger on the plane who's blind and deaf," she said. The passenger 4 to want something, 5 he was traveling alone and the flight attendants couldn't understand what he needed.

    Clara had been 6 ASL for the past year and knew she'd be able to finger spell into the man's palm(手掌). So she untied her seat belt, walked 7 the front of the plane, and knelt by the seat of Tim Cook, then 64. Gently taking his 8, she signed, "How are you? Are you OK?" Cook asked for some water. When it 9, Clara returned to her seat. The flight attendant 10 again a bit later because he wanted to know the time. On her third 11, she stopped and stayed for a while.

    "He didn't need anything. He was 12 and wanted to talk," Clara says. So for the next hour, that's 13 they did. She talked about her family and her plans for the future. Cook told Clara how he had 14 become blind over time and 15 stories of his days as a traveling salesman. Even though he couldn't see her, she "looked 16 at his face with such 17," a passenger reported.

    "Clara was 18," a flight attendant told Alaska Airlines in a blog interview. "You could 19 Cook was very excited to have someone he could speak to, and she was such an angel. And Cook said it was the best trip he'd 20 had."

    Months ago, I heard from a friend about a young lady who had just moved to our area. She was a 1from another country with only her small scholarship to make a 2and had just rented a small apartment. My friend told me she had few 3. I got the young lady's telephone number and called her, 4that I was a friend of a friend and I heard she might need some household 5She said, "Yes, thank you!" and6that she had slept on the floor of the apartment with only her coat to cover her and that it was a bit7.

    As every mother knows, when our children are away we 8 worry about them, and, everyone's child is my child too! So, I9a couple of my friends about her. One cleaned out her kitchen and10pots and pans, some glassware, a blanket. Another even11brand-new dishes and glasses in the supermarket.

    When we arrived at the girl's12, we saw there was no furniture. Someone had given her a sleeping bag, otherwise it was a(n) 13apartment. After unloading our 14 we took her back to campus. She 15me over and over again and could not16that these people gave her all these things. I explained people liked to help and that others had17us before. She asked if there was anything she could do to 18 us. I told her, "Yes, there is one thing you can do for us: when you are in a 19 to help others, please remember to20and help." With a smile on her face she promised me that she would.

    My father was born in a small town in the US. He wasn't sure what he wanted from1, but something told him to 2 and begin a new adventure.

    He began that adventure traveling to cities in the US before going on to Australia, New Zealand and the Philippines. He took my mother and us three daughters with him and went wherever the road 3 him.

    It's easy to feel 4 when you're on the road. We made lots of new friends on our trip — most of them are mechanics, since we often 5 hours in repair shops. But that was a way much 6 than sitting by the roadside while waiting for the engine to 7 when it was 40℃ outside.

    Getting along well sometimes seemed 8. There were always a lot of 9, especially among us back-seat passengers about who had to 10 in the middle. But even if it was hard, we learned a lot about 11. When we were traveling in the Philippines, we drove to Quezon City one day. It should have been an hour's drive but was nearly three thanks to bad roads and 12 traffic. "Did you put our suitcases in the car?" my father asked my mother as we arrived there. From the back seat, we saw her 13 turn toward my father. "No," she said. "I thought you did." That was how a seven-hour car trip turned into a 16-hour one, which was mostly spent in 14.

    On occasions like that, we had to learn to let go of our anger because we were 15 in a rolling box with the same people for the rest of the 16. Even if I sometimes felt like opening the car door and 17 one of my sisters out, I kept my feelings to myself.

    This is why road trips were like 18 universities to us. We 19 our PHDs(博士学位) in how to get along with other people just by traveling in our old car.

    If we were 20 given a second chance at life, we would do it all over again. Only this time would I put the suitcases in the car myself.

Research spanning several decades demonstrates that you are more likely to think the information that is repeated to be true than the information you hear only once. You usually assume that if people put in effort to repeat a statement, this reflects the truth of the statement. This tendency-also called the truth effect-is a bias （偏见） that can lead you to draw incorrect conclusions. 

To what degree are people aware of the truth effect? This question was addressed in a paper in the journal Cognition early this year. 

In the critical study in this paper, participants did two sessions. In one session, they read about a hypothetical （虚构的） study in which they were exposed to some statements and then were asked whether both statements they had heard before as well as these new statements were true. They were asked to predict the proportion （比例） of each statement that would be judged as true. They did this both as a prediction of other people's performance as well as a prediction of how they would do in this study. 

At another session a few days later, participants actually performed this study, reading a set of 20 statements in the hypothetical study again and then judging the truth of altogether 40 statements, half of which were from the hypothetical study and the other half of which were new. 

This study did replicate the well known truth effect. People were more likely to judge statements they had seen before as true than statements that were new. Two interesting findings emerged from the prediction. First, participants tended to underestimate the size of the truth effect for everyone. T hat is, while they did expect some difference in judgments between the statements seen before and those that were new, they thought this difference would be smaller than it actually was. Second, participants more significantly underpredicted the truth effect for themselves compared to that for other people. 

This study is particularly important in light of the amount of misinformation present in social media. Many people have the power to influence public opinion about important matters. Flooding social media feeds with misinformation will lead people to believe this information is true just because it is stated. Recognizing that we are all susceptible to this influence of repeated information should lead us to mistrust our intuition （直觉） about what is true and to look up important information prior to using it to make important judgments and decisions.
