用MRI检查骨折方面论述不正确的是（）
Passage2The way people work has changed. The increasing use of technology presents new and continual challenges to small and large businesses，employees and managers，teachers and students.Everyone，it seems，is being affected by the technological revolution. Store clerks，for example，now use increasingly complex computerized cash registers，while university professors must learn to adapt their teaching skills in order to lead distance learning course.In today's world，training and learning do not stop when we finish school；they must now continue throughout our working lives. The Hong Kong government conducted a survey on the employment concerns，and training needs of its workforce. For many managers and other professionals the biggest challenge，as well as change，in the workplace，was the increased use of computers and computerized machinery or equipment. The need for experienced employees who could use this kind of equipment rose drastically. Many of those in the workplace at this time experienced changes in job requirements and had to attend job-related training or re-training courses.The changing work environment is also affecting education and how we learn. In Finland, a report on strategies for education and training in the information age discussed the changing roles of both teacher and student. With the increased use of technology and the growth of distance learning, the teacher has become more of a tutor who guides a student, rather than a lecturer. In turn, the student has to take more responsibility for his or her learning in the absence of direct teacher contact. The report also stressed that high school and university students should learn computer skills in order to cope with the demands of the future workplace.The Finnish report also highlighted the need for teacher training, and re-training, and suggested that the salaries and job descriptions of teachers be reviewed because of future demands expected in their jobs. Previously university professors may have held lectures between the weekday hours of 9:00A.M. and 5:00 P.M. in large halls filled with students. Now, they may spend part of their day lecturing larger groups of students on campus, and then conduct afternoon or evening classes online, with students in five different countries.As technologies grow and develop, ongoing training will continue to be necessary. To be successful in the workplace, people will not stop learning when they leave school-lifelong learning will become a way of life.How did the changing work environment change the role of the teacher according to the Finnish report?
