But for your help，I ________ the place.
A．can’t find　　　　B．can’t have foundC．couldn’t have foundD．haven’t found
C

試題分析：考查虛擬語氣。本題考查的是but for(要不是…，如果沒有…)所引導的含蓄的虛擬語氣。句意：要不是你的幫助，我就不可能找到那個地方。根據(jù)句意說明你對我的幫助是過去發(fā)生的事情，所以使用“情態(tài)動詞+have done”的形式對過去的事情進行虛擬。故C正確。
點評：條件句的虛擬語氣也可以通過含蓄的條件來實現(xiàn)，如“but for…”,“without…”,要注意和具體的時間連用的形式的差別。
