【简答题】

The argument over a Philadelphia school district accused of secretly spying on pupils through laptop cameras became fiercer today after it acknowledged obtaining more than 56,000 images of its students, many of them in their homes. When the scandal (丑闻) first broke, it was believed that only a few pictures had been taken of one pupil, Blake Robbins. But court papers released this week showed that thousands of images were taken of Robbins and other students. Robbins and his parents have filed an action against the school district. Court papers from the Robbins’s lawyers said that at first it was thought that the laptops’ technology had produced a few images but they found more than 400 of Robbins, including images “showing him partially undressed and sleeping”. Robbins said he did not know why the spying device was activated (激活) as his laptop had not been reported stolen or missing. Other students whose pictures were taken said their laptops had not been reported stolen or missing either. An administrator at the school, one of the few with authority to track the laptops, remained silent, refusing to answer questions. The Philadelphia Inquirer reported that 38,500 of the images came from six laptops that had been reported missing from the Harriton gym in September 2008. These apparently helped the police catch a suspect. Another set of images were from cameras in laptops which employees responsible for tracking failed or forgot to turn off. The court papers, filed by Robbins’ lawyers, said that the technology was activated between 20 October and 4 November last year, with most of the 400 shots of him while he was in his home, and included his family. “There were additional webcam pictures and screen shots taken of Blake Robbins which, up to now, have not been recovered because the evidence was deleted by the IT department,” the court papers say. One of Robbins’ lawyers is trying to obtain access to the administrator’s home computer to confirm whether she downloaded any of the pictures. The court papers indicate she may be a voyeur (窥隐私者) though it has not been proved. 小题1:We can learn from the passage that _________. A.Robbins’ parents remained calm over the scandal B.Robbins had his laptop stolen before the scandal C.the laptops’ technology produced some images D.the private rights of the students were offended 小题2:What did The Philadelphia Inquirer say about the case? A.The police had found some evidence. B.Most of the laptops in Harriton gym were missing. C.Employees in charge of tracking deliberately left the laptops on. D.There was obviously more than one suspect related to the case. 小题3:According to the court papers, the administrator _________. A.may have spied her students on purpose B.may have broken into Robbin’s house C.has downloaded many students’ pictures D.has removed evidence from computers 小题4: What does the passage mainly talk about? A.Modern technology has negative effects on our lives. B.Students in Philadelphia are accustomed to being spied on secretly. C.A Philadelphia school is charged with spying students through laptop cameras. D.The American government should take measures to improve teachers’ qualities.
