1.Only when he started to explain( did she realize ) the reason for this.
就在他开始解释的时候,她才明白其原因.
Only强调状语置于居首时,使用部分倒装,即把谓语的一部分(助动词、情态动词和系动词be)放到主语前.本句中 Only 强调时间状语when he started to explain,所以答案应选B.
2.After that we never saw her again nor( did we hear )from her.
从那以后,我们再也没见过她,也没有关于她的任何消息.
否定副词、连词neither,nor,never,hardly,scarcely,little等及含有否定词的介词短语,如in no time等置于句首时,使用部分倒装.
3.Scarcely (had I entered) the room( when) the phone rang.
我一进房间电话铃就响了.
和上一题一样,scarcely放于句首句子使用部分倒装.另外,Hardly / Scarcely had sb.done sth.when...是固定结构.
b;a;c
当他开始解释的时候,她才明白原因;
自那以后,我们再也没见过她,也没听到关于她的任何消息;

第一句看到when,一般是指一个时间点而不是一段时间,所以没必要完成时的;
第二句看到nor,时态和never一致;...
