---- How does your second-hand car run?
---- It _____ run all right, but it is being repaired.| A．has | B．had | C．doesn’t | D．used to |
|
答案
| D |
解析
考查时态。注意but it is being repaired的含义及句中动词的形式“但现在正在被修理”，可知过去与现在的状态相反，因此表示过去的前半句中的谓语动词用过去式，可一下子排除A、B、C，表示“以前常常运转正常”。run用作动词，“开动（机器等）；经营”，如：run a forklift“操作叉车”，run this restaurant“经营餐馆”。 |
