一群学生在教室门口说笑。马上就要开始他们在校的最后一次考试了,他们充满自信,憧憬着考完这次试后,如何开始征服世界。考试铃声响了,他们走进教室。他们知道,这次考试会十分容易,因为老师说了,这是一次开卷考试,他们可以将他们想到的任何参考书带进考场,唯一的要求就是独立完成,考试期间不得互相讲话。老师将卷子发到了他们手上,卷上只有五道简答题。三个小时过去了,老师开始收卷子。然而,学生们迟迟不肯交卷。 A group of students joked at the door of the classroom. They are about to start their final exam at school, confident and looking forward to how to start conquering the world after the test. The exam bell rang and they walked into the classroom. They knew it was easy because the teacher said it was an open book exam and they could bring any reference book they thought into the examination room. The only requirement was that they should be done independently and they should not talk to each other during the exam. The teacher sent the paper to their hands, only five short answer questions. Three hours passed and the teacher began to rewinder. However, students are still too late to submit papers.
