2020 年高考英语时事热点拓展阅读 ( 十六 ) Passage1《科学美国人》：中学生作弊被神经网络捕获。 词数 285 建议阅读时间 4 分钟 The English -language version of Wikipedia has almost six million articles. And if youre a cheating student, thats six million essays already written for you, footnotes and all. Except plagiarism isnt really an effective tactic — just plug the text into a search engine and game over. But what about having a ghostwriter at a paper mill compose your final essay? Standard plagiarism software cannot detect this kind of cheating. Stephan Lorenzen, a data analyst at the University of Copenhagen. In Denmark, where hes based, ghostwriting is a growing problem at high schools. So Lorenzen and his colleagues created a program called Ghostwriter that can detect the cheats. At its core is a neural network trained and tested on 130,000 real essays from 10,000 Danish students. After reading through tens of thousands of essays labeled as being written by the same author or not, the machine taught itself to tune into the characteristics that might tip off cheating. For example, did a students essays share the same styles of punctuation? The same spelling mistakes? Were the abbreviations the same? By scrutinizing inconsistencies like those, Ghostwriter was able to pinpoint a cheated essay nearly 90 percent of the time. The team presented the results at the European Symposium on Artificial Neural Networks, Computational Intelligence and Machine Learning. And theres one more aspect here that could help students. Your high school essays presumably get better over time as you learn to write — and the machine can detect that. The final idea is to detect students who are  at risk  because their development in writing style isnt as youd expect. Teachers could thus give extra help to kids who really need it, while sniffing out the cheaters too. 重点讲解： 1. and all 等等；甚至包括； He dropped his sausage on the pavement and someones dog ate it, mustard and all . 他把香肠丢在人行道上，不知是谁家的狗将香肠甚至连带芥末都吃个了精光。 2. be able to do sth.
