题目内容
The petrol tank is empty. I _________it up before we left home.
| A．had to fill | B．would have filled |
| C．should have filled | D．could have filled |
C
解析试题分析：根据本句中的before we left home可知这是对过去情况的虚拟。对过去情况的说明使用“情态动词+have done”，排除A项。Would have done本想做某事；should have done本应该做某事，实际上却未做；could have done本可以做某事，实际上却未做；句义：油箱空了，在离开家之前，我本应该把油箱加满的。故C正确。
考点：考察情态动词用法
