问题补充：

When I got home last night, my parents for me at the table.

A. wait

B. waited

C. were waiting

D. have waited

答案：

A. wait

B. waited

(答案→)C. were waiting

D. have waited

解析：句意:昨天晚上当我到家的时候，我的父母正在桌子旁边等我。wait 等，等待。根据句意可知，这里说的是昨天晚上的事情，应该用过去时态，故可先排除A和D。B选项是一般过去时，C选项是过去进行时，根据句意可知，C选项更符合这个情景。故选C。
