A、The software can not solve the students’ problems at all. B、The software is designed for editors and writers, not the students

How might you drag a good writer’s work down to the lower level? Try the spell-check button. A study at the University of Pittsburgh indicates spell-check software may level the playing field between people with differing levels of language skills. hampering the work of writers and editors who place too much trust in the software.
     (33)In the study, 33 undergraduate students were asked to proofread a one-page business letter—half of them using Microsoft Word with its red and green lines underlining potential errors. The other half did it in the old-fashioned way, using only their heads. (34)Without grammar or spelling software, students with higher SAT verbal scores made, on average, five errors, compared with 12.3 errors for students with lower scores. Using the software, students with higher verbal scores reading the same passage 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. (35)"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. (35)The study found the software helped students find and correct errors in the letter, but in some cases they also changed phrases and sentences flagged by the software as grammatically suspicious, even though they were correct.
