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

For this month's Young World magazine，I interviewed 19﹣year﹣old Asian pop star Candy Wang．Candy told me that she used to be really shy and took up singing to deal with her （66） （shy）．Now she's not shy anymore and enioys （67） （sing） in front of crowds．
I asked Candy how life was diffierent after she became famous．She explained that there are many good things，like being able （68） （travel） and meet new poople all the time，"I didn't use to be popular in school，but now I get tons of attention everywhere I go"（69） （however），too much attention can also be a bad thing，"I always have to worry about how I appear to others，and I never dare to be （70） （care）about what I say or do．And I have much （71） （little） private time now because there are always guards around me．"
What does Candy have to say to all （72） （that）young people who want to become famous？"Well，"she begins（73） （slow），"you have to be prepared to give up your normal life．You can never imagine how dificult the road to success is．Many times I （74） （think） about giving up，but I fought on．You really require a lot of talent and hard （75） （work） to succeed．Only a very small number of people make it to the top"．
