问题 But for their help, we ______.
选项 A、shouldn’t succeed
B、could not have succeeded
C、will not succeed
D、should not have succeeded
答案 B
解析 本题考查的是情态动词表示虚拟语气。But for“要不是”，是对过去情况的假设，主句要用过去将来完成时。基本结构就相当于：If…．had not…，…would have done。在这里用 could not have done，表示：本不能…(实际上做到了)。所以选 a本句意思是：要不是他们帮忙，我们本不会成功的。
