    Recently, Chongqing Three Gorges University has held an activity named “Cell Phone Ninja”(手 机忍者). They would like their students not to use cell phones for 21 days. It is really a challenge( 挑 战)for most students.

    The activity started on April 12. Each student who volunteered to take part in this activity got a bracelet(手环). If the students did not use their cell phones, there would be a photo on the screen of the bracelet to show that. If they used their cell phones, a different photo would appear on the screen of the bracelet. After the last class of each day, the students sent the photos to the school's public Wechat.

    More than 800 students wished to take part in this test, and 400 were chosen. After seven days, only 103 students remained. The test was set for 21 days because some scientists believe that 21 days is long enough to help people form a habit.

    According to the teachers in the university, the activity was not a competition. It depended on students themselves to make the decision. The teachers hoped their students could form better study habits through activities like this one.

    In the Middle Eastern country of Lebanon, there are more than 1 million refugees (难民). Youssef was 10 years old when a local Syrian musician discovered his talent: a deep, powerful voice-well-suited to traditional songs. However, Syria's civil war took place soon. He and his family lost their home.

    When the Action for Hope Music School announced that it was looking for talented children to train, his family encouraged him to attend the school. A year and a half later, Youssef, with another 11 children, was chosen to take part in a concert.

    Youssef, a shy boy, was a lead singer in the concert. He gave a confident performance of traditional Syrian songs. "We only heard the sound of a mortar(迫击炮）. It fell near us. A whole building came down. That is all I remember," said Youssef. "Music makes me forget everything. Music is the most important thing."

    Basma, director of Action for Hope, said," The music school offers children who suffer from the war strength (力量). They can find a good way to express themselves and stop thinking of themselves as refugees."

    "Art gives strength. It comes from the ability to create," Basma said, "People who are in difficult conditions need this strength much more than the rich."
