问题 Toughened hiring standards have not been the primary cause of the present staffing shortage in public schools. The shortage of teachers is primarily caused by the fact that in recent years teachers have not experienced any improvements in working conditions and their salaries have not kept pace with salaries in other professions. Which of the following, if true, would most support the claims above?

选项 A、Many teachers already in the profession would not have been hired under the new hiring standards.
B、Today more teachers are entering the profession with a higher educational level than in the past.
C、Some teachers have cited higher standards for hiring as a reason for the current staffing shortage.
D、Many teachers have cited low pay and lack of professional freedom as reasons for their leaving the profession.
E、Many prospective teachers have cited the new hiring standards as a reason for not entering the profession.

答案D

解析 短文排除了一种对于缺乏教师的解释——由于更苛刻的雇用标准——并提出了一种替代的解释——教师缺乏是由于工资低和工作条件不佳,选项(D)通过指出对于许多前教师来说,低工资和工作环境差是他们放弃这项职业的原因,为后面这种解释提供了支持性的证据,因此,(D)是正确答案;选项(A)、(C)和(E)提供了证据显示新的雇用标准和师资缺乏有关,从而支持了短文反对的一种解释;选项(B)描述新雇用标准的一种可能的结果,但它没有提供证据来支持关于师资缺乏的一种解释优于另一种解释
