问题补充：

---where have you been?

---Iin the heavy traffic, or I would have been here earlier.

A. stuck

B. had stuck

C. have been stuck

D. got stuck

答案：

A. stuck

B. had stuck

C. have been stuck

(答案→)D. got stuck

解析：考查动词的神态和语态。根据would have been可知指的是过去发生的情况，所以要用过去时态，排除C；且主语I和stick之间是动宾关系，所以要用被动语态，所以选D，get+过去分词，是被动语态的一种表达方式。
