题目内容
Only after Mary read her essay the second time the spelling mistake.
A. did she notice. B. she notice.
C. does she notice D. she has noticed
【答案】
A
【解析】
试题分析:考查Only引导的部分倒装。句意:只有当玛丽第二次读了文章,她才注意到拼写错误。Only的倒装有两个条件:only放在句首;且强调的是状语。本题中only放在了句首,强调的是时间状语从句after Mary read her composition the second time;所以后面使用倒装句的形式;根据上文的read说明本句使用过去时。故A正确。
考点:考查only的倒装
