【正确答案】 C

【答案解析】[分析] 这是一个虚拟条件句，条件从句没有用if引出，而是用介词without引出，without your help就相当于条件从句if I hadn't had your help，除了用without表示条件外，还可用with, but for, or, but, other-wise, even, in case of, what if等词表示条件。如：But for your help we couldn't have succeeded. 要是没有你的帮助，我们不可能取得成功。With better equipment，we could have done it better. 如果有好的设备，我们能做得更好。
