Question

这道题到底选什么 我认为选C 但有人认为选B

.often _____ them not to smoke here.
A. we advised B. advised me C. did we advise D. had we advised

选B 不是因为often 频度副词放句首，用部分倒装嘛
请求高人指点

Answer 1

now,then,just,often等表示时间的副词放在句首，用来引起人们的注意。
规则：主谓调换，不加助动词。但主语是人称代词时，主、谓语序不变。

例1: Often we advised them not to smoke here.
例2: Now comes your turn to recite the text.
