Only after they had discussed the matter for several hours ______ an agreement. A．they reached B．do they reach C．they reach D．did they reach

Answer 1

D

试题分析：考查倒装句。当only放在句首，且强调的是状语的时候，后面的主句使用部分倒装的形式。本题only放在句首，强调的是时间状语after they had discussed the matter for several hours,故后面使用部分倒装的形式，因为时态had discussed说明这里使用一般过去时。句意：只有当他们讨论了几个小时以后，他们才达成了一致的意见。故D正确。 点评：当only放在句首，且强调的是状语的时候，后面的主句使用部分倒装的形式。
