Only after Mary read her composition the second timethe spelling mistake.

(·天津，6)

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：A

解析句意为：只有当玛丽再次读她的作文之后她才注意到这个拼写错误。“only＋状语/状语从句”位于句首时，主句须用倒装语序。after引导的是时间状语从句，接在only之后，位于句首，所以主句要用倒装，可排除B、D两项。而且根据语境知read和notice都是过去发生的动作，所以答案为A项。
