A.is going    B.had been   C.was about   D.is coming

这里的“打算”用一般将来时还是过去将来时？

【答】 C.was about 是正确答案。was / were about to do sth. ... when ... 这个句型的意思是：“刚刚 ......, 这时（突然）......” when的前面可以用或者不用逗号，when 后面的谓语动词通常用过去时。例如：I was about to go to bed, when he called me up. 我正要上床睡觉的时候，他打电话来了。（摘自外研社、建宏《英汉多功能词典》，1997年1月第1版）We were about to start when it began to rain. 我们刚要出发，就开始下雨了。
