Question

求解析 谢谢！！！！！！

Answer 1

选C
no sooner....than 固定用法"一...就..."
引导时间状语从句, no sooner后用完成时，than后面的从句用一般时态
No sooner ...than...常放在句首,表示强调.这时no sooner从句要半倒装，即将助动词has/had等提前
例:No sooner had I reached home than it began to rain.

Answer 2

我觉得可能选项有问题，原句用的是一般过去式，所以答句必须也是过去的，c选项显然不合适。正确的答案全文应该是这样的。
No, no sooner had she gone than it happpened.
依据no sooner...than..的用法，主句用过去完成时，从句用一般过去时。而且no sooner置于句首，句子需要倒装。
希望能有所帮助！
