问题
___________your valuable help, we couldn’t have finished the experiment ahead of time.
选项
A、If it were not for
B、Had it not been for
C、Were it not for
D、If it has not been for
答案
B
解析
考查虚拟语气。由主句谓语可知,本题是与过去事实相反的虛拟条件句,条件从句谓语用“had +过去分词”,如果省略if,句子要倒装,倒装时要将助动词提前,即把had移到主语前面。句意:如果不是你有价值的帮助,我们就不会提前完成实验,故选B。
