Question

【题目】阅读下文并回答问题。
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 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.
（1）When did the activity “Cell Phone Ninja” start?
（2）Were 400 students chosen to take part in this test?

【解析】短文大意：近日重庆三峡学院举行了一个叫“手机忍者”活动。他们希望他们的学生不要使用手机21天。对于大多数学生来说这真是一个挑战。根据大学的老师，这一活动不是一个竞争。这取决于学生自己的决定。老师希望他们的学生能通过这样的活动形成更好的学习习惯。
（1）根据第二段中The activity started on April 12.可知这个活动开始于四月十二日。所以作答It started on April 12.
（2）根据第三段中More than 800 students wished to take part in this test, and 400 were chosen.有四百名学生被选中参加了这个测试，多以作答Yes, they are.
（3）根据第三段中The test was set for 21 days because some scientists believe that 21 days is long enough to help form (形成) a habit.可知测试定位二十一天是因为一些科学家认为二十一足以帮助形成习惯。所以作答Because (some scientists believe that) 21 days is long enough to help people form a habit.
（4）根据第二段中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. 可知这些手环是用来表明学生使用手机了还是没有，所以作答It was used for showing/ to show whether the students used the cell phone(s) or not.
