______________________Students could not bring cell phones or calculators into the rooms. Teachers did not have the chance to tell students the answers to the exam questions. The government employed monitors to watch the test-takers carefully. Why was last year different from earlier years? ______________________考生们将不能带手机或者计算器进入考场.教师们就无法告诉学生考试答案了.政府还安置了监控器来监督考生.为何去年的考试和往年都不同呢?
