No. 11 High School in Hangzhou is using facial recognition technology 【小题1】(analysis) the behavior of students in the classroom, and to keep a record of their attendance. The system involves a facial recognition camera 【小题2】 scans the classroom every 30 seconds. The camera is designed to log six types of behaviors by the students: reading, writing, hand raising, standing up, listening to the teacher, and leaning on the desk. It also records the facial expressions of the students and logs whether they look happy, upset, angry, fearful or 【小题3】 (disgust). The information collected by system can help teachers better supervise the performance of their students. On top of that, the system can help teachers rethink their teaching method 【小题4】 (use) statistical data, as well as cut the time needed to check class attendance 【小题5】 only a few seconds.

However, 【小题6】 are some concerns about students’ privacy among the public. Zhang Guanchao, the school's vice principal, explained that privacy was considered in the design of the system, saying "Data collection and application focus on behavior 【小题7】( manage) of the entire class rather than any individuals." He also emphasized that the system 【小题8】 (it) is not connected to a cloud server, 【小题9】 to a local server, in order to prevent unauthorized access to the data.

Facial recognition technology 【小题10】 (extend) into many areas of school life so far. For example, facial recognition is used to pay for purchases at the school shop and to borrow books from the school library.

We used to appreciate those 【小题1】 like to help strangers. But nowadays some people tend to be very 【小题2】(care) in helping strangers. Our class 【小题3】(have) a discussion about whether we should help strangers or not last week. Opinions are different on this topic.

Some think we should try to help others whether they are strangers or not. Helping others is 【小题4】 virtue, and it will make our society more harmonious. Besides, helping others is helping ourselves. We may come across some trouble 【小题5】 need others’ help some day. If everyone turns a blind eye to our trouble just because we are strangers to them, it’s hard 【小题6】(imagine) what our world will be like. However, others are afraid that helping others can sometimes bring them trouble or even put them in danger. Sometimes we 【小题7】(misunderstand) and thus have to pay the cost of kindness.

In my opinion, we should try 【小题8】(we) best to help others when they are 【小题9】 need of help, but we should also protect ourselves from 【小题10】(get) into trouble.

Nowadays, there exists a common phenomenon. A man walks 【小题1】 the sidewalk, a smartphone in hand and completely absorbed in the digital world. Just as 【小题2】computers achieved before, smartphones are now changing our life. I am truly grateful for the convenience brought by it. But meanwhile I feel deeply anxious. To stay informed, I constantly update my WeChat.
