题目内容
7.Only after they had discussed the matter for a few hours _______a decision.( )| A. | they reached | B. | did they reach | C. | they reach | D. | do they reach |
分析 句意为:只有在他们把这个问题讨论了几个小时后,他们才得出结论.
解答 答案:B 本句中only位于句首,强调状语,主句需要部分倒装,根据句意,主句应该用一般过去时态,所以借助于助动词did.故本题选择B.
点评 考查倒装句式时,要注意句中开头的词语,还要注意是用部分倒装还是完全倒装.
