题目内容
Only after Mary read her composition the second time________the spelling mistake.
(2012·天津,6)
A.did she notice? B.she noticed
C.does she notice? D.she has noticed
【答案】
A
【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。
