问题补充：

—I thought I asked you to fix the radio.

— Oh. I’m sorry，dear. I it right away.

A. am to do

B. will do

C. was about to do

D. am going to do

答案：

A. am to do

(答案→)B. will do

C. was about to do

D. am going to do

解析：根据语境，可知我一开始忘了。所以不能说是“准备去做某事”，所以AD都不能选。beaboutto表示“正要，就要”，不能和rightnow连用。所以只能选B, 表示将要。
