If it ____for the snow, we____ the mountain yesterday.
A．were not, could have climbedB．were not, could climb
C．had not been, could have climbedD．hadn’t been, could climb
C

試題分析：考查條件句的虛擬語氣：句意：要不是因為昨天的雪，我們就會爬到山上了�？芍@是和過去相反的if虛擬條件句，if從句用If主語+had+done；主句：主語+should/would/could/might+have done，選C。
點評：if的虛擬語氣非常重要，簡要概括如下：1、表示與現(xiàn)在事實相反的情況，從句：If主語+過去時(Be動詞用were)；主句：主語+should/would/could/might+do：　2、表示與過去事實相反的情況，從句：If主語+had+done；主句：主語+should/would/could/might+have done　3、表示對將來情況的主觀推測，從句：①if+主語+were to do②if+主語+should+do ③if+主語+did（動詞過去式）/were ；主句：主語+should/would/could/might+do
