有一读者问这样一个句子：
(1)If you come out for a walk, you are going to feel much better.
据说这句话是错的，句中的are going to应改为will。我不知这种改法是否正确？
在这个问题上，似乎是有争议的。这句话用will无疑是规范英语，无人会对之提出异议。但如用are going to就会有人反对了，说它是不规范英语。我们的看法是： 在当代英语中，尤其是在美国英语中，“If..., ... be going to...”并不罕见，特别是当be going to表意向的时候，例如：
(2)If Tom passes the examination, his father is going to buy him a bicycle.
(3)If I have enough money, I'm going to take a trip abroad.
但be going to即使没有意向的含义，结果从句中亦可用be going to，例如：
(4)If we don't send him to the hospital quickly, it's going to be too late.
(5)What am I going to do if something happens to her?
(6)If you invite Jack, there's going to be trouble.
这种用法甚至出之于前美国国务卿基辛格之口：
(7)If they harass you after you leave office, I am going to resign as Secretary of State, and I am going to tell the world why! （这是基辛格对即将辞职的尼克松总统讲的话）
