__he realized it was too late to return home A h __he realized it was too late to return home A hardly did it grow dark when B it was not until dark that
如果选A,则选用了hardly...when...句式,该句式要求前句采用过去完成时即had done,而when后面的句子采用一般过去时,且前句一般部分倒装,即把助动词had提到主语前. 但是答案A中把did提前,说明是一般过去时,而不是过去完成时,所以A错误. 即A需改成:Hardly had it grown dark when才对. B采用了not...until的强调句型,为正解.
