Thank you for giving me a hand. I ______ in the experiment without your valuable help.
A．have failed
B．will fail
C．would have failed
D．must have failed
答案
答案：C
考查含蓄条件句。该句用介词短语表达条件，即：I would have failed in the experiment without your valuable help.="I" would have failed in the experiment if I hadn’t got your valuable help.如果没有你宝贵的帮助，我本会实验失败的。
