開頭應該為:If it had not been.....,而if可以被省略變成選項A以下為if省略的句型練習:Had例. Had he done it, he would have felt sorry. = If he had done it, he would have felt sorry.Should例. Should he tell lies, I would punish him. = If he should tell lies, I would punish him.Were例. Were he lazy, he might fail. = If he were lazy, he might fail.
