A解析试题分析：考查虚拟语气的省略：句意：要不是你的帮助，我不会取得进步的。如果条件句中有were,had,should 等助动词，可将if省略，而把were,had或should，置于句首,来表达以if引导的条件句的相同意思。根据后面的主句I couldn't have made any progress．可知这里是had it not been for your help相当于If it hadn’t been for your help。选A。考点：考查虚拟语气的省略倒装点评：当虚拟条件句的谓语部分含有were, should, had时，我们可以将连词if省略掉，而将were, should, had置于句首。如果条件从句为否定式，注意要将not置于主语之后，而不置于主语之前
