As the experiment unfolded, the pupil would definitely give the wrong answers to questions posed by the teacher, thereby bringing on various electrical punishments, even up to the danger level of 300 volts and beyond.(剑5, Test 1 passage 2)

　　● 分析：

　　本句主句“the pupil would definitely give the wrong answers to questions”; “As the experiment unfolded”为As引导的时间状语从句，做该主句的时间状语;“posed by the teacher”为过去分词短语作定语，做questions的定语;“bringing on various electrical punishments, even up to the danger level of 300 volts and beyond”为现在分词短语作状语，做主句的伴随状语。
