After ___seemed an endless wait , it was her turnto enter the personnel manager's office.
A that B there C what D it
參考答案:句意】在经过一段似乎是漫无边际的等候之后，终于轮到她走进医生的办公室。
【难点】在由after引导的介词短语中，what seemed(to be)起定语作用，修饰an endless wait。又如：I saw what seemed to be a fox.（我看见一个似乎是狐狸的东西。）
这样的用法很常见，下面是节自奥威尔小说中一句：
At last, after what seemed a long time (it might have been five seconds, I dare say) he sagged flabbily to his knees.
