How might you drag a good writer's work down to the level of a scribe (抄写员)? Try the spell-check button．A study at the University of Pittsburgh indicates spell-check soft-ware may level the playing field between people with differing levels of language skills, hampering (妨碍) the work of writers and editors who place too much trust in the software．In the study, 33 undergraduate students were asked to proofread (校对) a one-page business letter half of them using Microsoft Word with red and green lines underlining potential errors (潜在错误)．The other half did it the old-fashioned way, using only their heads．Without grammar or spelling software, students with higher SAT scores made, on average, 5 errors, compared with 12．3 errors for students with lower scores．Using the software, students with higher scores reading the same page made, on average, 16 errors, compared with 17 errors for students with lower scores．Dennis Galletta, a professor of information systems at the Katz Business School, said spell-check software is so sophisticated that some have come to trust it too thoroughly．It's not a software problem, it's a behavior problem, he said．Microsoft technical specialist Tim Pash said grammar and spelling technology is meant to help writers and editors, not solve all their problems．The study found the software helped students find and correct errors in the letter, but in some cases they also changed phrases or sentences marked by the software as grammatically suspicious (可疑的), even though they were correct．
