If these kind-hearted soldiers ___ us last week, we would not have such a good harvest.
A．helpedB．had helpedC．had not helpedD．didn’t help
C

試題分析：考查錯綜時間條件句。從主句 would not have可以看出與現(xiàn)在相反，再觀察從句狀語 last week可知，從句與過去相反，使用had done,結(jié)合句意,應用否定，故選C。句意，如果這些熱心的戰(zhàn)士上周沒有幫助我們，我們就不可能有這么好得收成。
點評：注意辨認if的錯綜時間條件句。虛擬語氣的考查要注意分清主從句是與過去，現(xiàn)在還是將來相反，并熟記主,從句的虛擬規(guī)則
