Question

【題目】閱讀下文并回答問題。
Recently, Chongqing Three Gorges University has held an activity named “Cell Phone Ninja” (手機忍者). They would like their students not to use cell phones for 21 days. It is really a challenge (挑戰(zhàn)) for most students.
The activity started on April 12. Each student who volunteered to take part in this activity got a bracelet (手環(huán)). 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?

【解析】短文大意：近日重慶三峽學院舉行了一個叫“手機忍者”活動。他們希望他們的學生不要使用手機21天。對于大多數(shù)學生來說這真是一個挑戰(zhàn)。根據(jù)大學的老師，這一活動不是一個競爭。這取決于學生自己的決定。老師希望他們的學生能通過這樣的活動形成更好的學習習慣。
（1）根據(jù)第二段中The activity started on April 12.可知這個活動開始于四月十二日。所以作答It started on April 12.
（2）根據(jù)第三段中More than 800 students wished to take part in this test, and 400 were chosen.有四百名學生被選中參加了這個測試，多以作答Yes, they are.
（3）根據(jù)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.可知測試定位二十一天是因為一些科學家認為二十一足以幫助形成習慣。所以作答B(yǎng)ecause (some scientists believe that) 21 days is long enough to help people form a habit.
（4）根據(jù)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. 可知這些手環(huán)是用來表明學生使用手機了還是沒有，所以作答It was used for showing/ to show whether the students used the cell phone(s) or not.
