问题补充：

Not until Mary reads her composition the second time the spelling mistake.

A. did she notice

B. she noticed

C. does she notice

D. she has noticed

答案：

(答案→)A. did she notice

B. she noticed

C. does she notice

D. she has noticed

解析：考查倒转句。当否定词或者半否定词放在句首时，后面构成部分倒装的形式。句意：直到Mary又一次读那篇作文，她才注意到那个拼写错误。根据前面的Mary read,说明本句是一般过去时时。而否定词not放在句首了，故A正确。
