(3)Because(somescientistsbelievethat)21daysislongenoughtohelppeopleformahabit.

【解析】

(1)近期，重庆三峡学院举行了一个名为“手机忍者”的活动。他们想让他们的学生21天不要使用手机。这对大部分学生来说真是一个挑战。这次活动开始于4月12日。每一个志愿参加的学生都得到了一个手环。如果学生没有使用手机，手环上就会有一张图片来表明他没有使用手机。如果他们使用了手机，手环上就会出现一个不同的图片。在每一天的最后一节课，学生们将这些图片发给学校的公共微信上。多于800名学生愿意志愿参加这次测试，并且有400名学生被选上。七天之后，只剩下103名学生。这次测试被设定为21天，是因为科学家们认为21天是一个足够长的时间去形成一种习惯。根据大学里的老师们说，这次活动不是一个比赛。这取决于学生们自己去做决定。教师们希望他们的学生通过这样的活动来养成更好的学习习惯。

细节理解题。根据第二段第一句“TheactivitystartedonApril12.”可知活动开始的时间是4月12日。回答时，可用it代替问句中的主语theactivity"CellPhoneNinja"。根据问句中的did，可知时态应该用一般过去时。故答案为ItstartedonApril12.

(2)细节理解题。根据“Morethan800studentswishedtotakepartinthistest，and400werechosen.”可知800多人报名参加，只有400人被选择。故应做肯定回答。故答案为Yes,theywere.

(3)细节理解题。根据“Thetestwassetfor21daysbecausesomescientistsbelievethat21daysislong
