text into a search engine and the game is over. Then what about having a ghostwriter compose your final essay?
“Standard plagiarism software cannot detect this kind of cheating.” said Stephan Lorenzen, a data analyst at the University of Copenhagen. In Denmark, where he’s 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 central part is a neural (神经的) 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 student’s essays share the same styles of punctuation? The same spelling mistakes?
By examining inconsistencies like those, Ghostwriter was able to seek out a cheated essay nearly 90 percent of the time. The team presented the results at the European Meeting on Artificial Neural Networks, Computational Intelligence and Machine Learning. There’s one more aspect here that could help students. Your high school essays probably 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 isn’t as you’d expect. Teachers could thus give extra help to kids who really need it, while sniffing out the cheaters too. 32. What can be true about a cheating student trying to finish an essay? A. His cheating may be detected in a certain way. B. Essays offered by WikiPedia can’t be downloaded. C. He won’t hire a ghostwriter to write one for himself.
D. Ghost cheating can be detected by Standard plagiarism software. 33. Which aspect of the program “Ghostwriter” is talked about in Para. 3?
A. Its components. B. Its weaknesses. C. Its influences. D. Its working theory. 34. Which one of the following is the function of “Ghostwriter” ? A. It never fails to find out a cheated essay. B. It can detect a student’s progress in writing. C. It can guide a student to correct his writing style. D. It relieves teachers of giving extra help. 35. Where is the text most likely from? A. A guidebook. 32. A
B. A magazine.
C. A novel.
D. A diary.

North America's birds are disappearing from the skies at a rate that's shocking even to ornithologists （鸟类学家）.Since the 1970s, the continent has lost 3 billion birds, nearly 30% of the total, and even common birds such as sparrows and blackbirds are in decline, U.S. and Canadian researchers report this week online in Science. The findings raise fears that some familiar species could go the way of the passenger pigeon, a species once so abundant that its extinction in the early 1900s seemed unthinkable.
The results, ever done to North American birds, point to ecosystems in disorder because of habitat loss and other factors, researchers say. Yet ecologist Paul Ehrlich at Stanford University, California sees some hope in this
