单选题 We can infer from the passage that in the past an employee ______.

A、 had job security and opportunity of promotion
B、 had to compete with each other to keep his job
C、 had to undergo training all the time
D、 had no difficulty climbing the corporate ladder

【正确答案】 A

【答案解析】从第一段的句子“it is much harder than it used to be to offer good employee job security and an opportunity to climb the corporate ladder．”可以看出，过去一个好的职员很容易获得事业保险(job security)和晋升的机会(opportunity to climb the corporate ladder)，工作上的竞争并不残酷，所以B“(必须和别人竞争”不对，C“必须总是接受培训”过去没有，D故意曲解了句子的意思。因此答案应该是A。
