I was going to visit my friend in Tianjin, but I ________ TO GO ABROAD FOR OUR SUMMER HOLIDAY WITH MY PARENTS NOW.
参考译文：我原计划去看望我印度的朋友，但我目前决定和我的爸爸妈妈去海外度暑假。
A. have decided B. had decided C. would decide D. decided
答案为A，为何用完成时，不需要D 呢？谢谢!!
答案分析A：
前分句：过去以后时态，表示在过去某一时间范畴看以后发生的动作。
后分句：目前完成时态，表示目前我决定和我爸爸妈妈去海外度大家的暑假。（这里用目前完成时态表示是目前瞬间完成的态度和决定，是主语目前临时做出瞬间变化的决定。即做出与之前不同想法的决定。而且这个动作是在瞬间完成。）,不可以用通常过去时态，通常过去时态只不过说明主语在过去某一时间做某事情的（态度和决定），不涉及到目前的状况。故不可以用通常过去时态。
I have changed my mind now.
I have arrived home now.
I have finished my homework now.
