  • 第6题:

    The difference between “gentleman-in-waiting” and “journeyman” is that _____ .

    [A] education trained gentleman-in-waiting to climb higher ladders

    [B] journeyman was ready to take whatever was given to him

    [C] gentleman-in-waiting belonged to a fixed and high social class

    [D] journeyman could do practically nothing without education


    正确答案:C

    本题考查了具体的细节。解题的关键在于考生对文中关于两类人的论述的把握。文章第一段末句提到,教育成了培训,学生也不再是等在那里的绅士,而是要提升自己经济地位的熟练学徒。由此可知,“学徒”与“绅士”的不同就是,绅士不用将教育当成工具去努力争取社会地位,因此可以推测出绅士们属于较高的社会阶层。[C]为正确选项。文中提到教育训练学徒们而非绅士爬上更高的阶梯,所以[A]项错误,[B]项和[D]项在文中没有相关论述。
