A photo of the students wearing theanti-cheating hats made its way to the Internet, and theuniversity was criticized for making students wear thoseridiculous looking homemade hats. The hats were made bystapling pieces of paper onto a headband, one to each side of the head.After being criticized, senior academic staff at Kasetsart University in Bangkok, Thailand, released a statement saying that the hats idea came from students. They said that in a bid to prevent cheating they asked the students for ideas on how to prevent cheating in the upcoming exam, which was being taken by almost one hundred students. Students cam e up with different ideas, then the paper hat idea was selected by them as the most suitable.The university claimed that no one was forced to use the hat, but they all chose to do so. “When wearing the hat during the exam, students felt more relaxed, ”Na ttadon Rungruangkitkrai, a lecturer at the university said. “It was not meant to indicate that Kasetsart students often cheat on exams. I apologize if the photo makes other people look at my students in a negative way, ”Rungruangkitkrai added.【文章大意】很多人在一起考试对监考老师来说压力不小。

One day, he walked into the Union Trust Bank in Waltermore and took $50,000 that did not belong to him. The guards and other employees stood back and let him stuff the bills into his shirt and pants without trying to prevent him from taking the money. No one pressed the alarm. No one pulled a gun. No one called the police. Why did they allow him to get away with it? Well, everything was legal. Peter had won contest promoted by a Waltermore radio station. The first prize entitled him to enter the Union Trust Bank and gather up as much money as he could lay his hands on within five minutes. Because he could not bring any large sacks or boxes into the bank, all the money had to be placed in his pockets. As the time went by, Peter ran about wildly and tried to pick up as many large bills as he could find. When his time was up, he was out of breath, but he was $50,000 richer.。
