【答案解析】[听力原文]
   W: The Education Department has called on teacher unions to accept current salary reductions or face layoffs during the school year. Teacher unions responded by threatening to strike if the Department attempts to push through these policies. A union spokesperson warned that while they don't want to interrupt the beginning of the school year with a strike, they will do so if their demands concerning salaries and education policy are not met. Of greatest concern is the threat of teacher layoffs, which would affect over 8,000 students in Clark and Barry Counties. Some see risk in the unions' hard line during these tough economic times. Teachers risk appearing out of touch with economic realities as they refuse to give up on their demand for pay increases.
选项A错误，被解雇是教师所担忧的事情，而不是教育部人员。选项B和C均未提及。选项D正确。
