After seemed an endless wait, it was her turn to enter the personnel manager's office．
A. that
B. how
C. what
D. why

A. thatB. how(答案→)C. whatD. why解析：宾语从句属于名词性从句一种，名词性从句分为主语、宾语、表语、同位语从句四种，除宾语从句外，同位语从句和定语从句的区别是高考常考点。宾语从句中的连接词that, whether, if在句中不充当任何成分，只起连接作用；连接代词who(ever), which(ever), whom(ever),whose(ever),what(ever)在句中做主语，宾语，表语和定语；连接副词when, why, where, how，在句中做状语。应从上下句的句法关系着手分析，切不可‘望句形生答案’总的来说，考生在解答此类题型时，可用排除法，造句法或者还原法，造句法就是仿造原句的语法功能仿造出一个易懂易理解的句子，帮助判断。本句的what引导起介词after后面的宾语从句，what在句中做主语。句义：在似乎没有尽头的等待一句，轮到他进入人事经理的办公室了。A项不能在句中做成分，BD不能做主语。故C正确。
