where are you going?what are you doing?
where are you going?我理解它为be going to一般将来时的疑问句形式.
我回答：I am going shopping.或者I am going to shop.
what are you doing?我理解它为be+Ving现在进行时的疑问句形式.
我回答：I am doing shopping.或者I am doing to shop.
这些句子中的动名词和不定式这样互换有错误么?
因为不定式to shop等于动名词shopping.我是这么换的.

不对,不能互换,而且I am doing shopping和I am doing to shop的回答都是错误的,what are you doing?的意思就是你要去做什么,回答是我要去买东西,那因为的去买东西的词组不就是go shopping吗?在此处是一般将来时所以用be going to结构,所以回答按一般语法应该是I am going to +动词（go)+宾语,但go这个动词比较特殊,它的一般将来时是be+动词go的动名词结构来表示将来时,所以正确的回答就变成了I am going（此处的 going并不是指be going to结构中的going,而是实义动词go的动名词结构）shopping.
二楼说的根本不对,I am doing shopping.或者I am doing to shop.这两个回答都不正确,根本没有直接用do shopping表示去购物的.where are you going?和what are you doing?的回答都应该是I am going shopping.

where are you going?what are you doing? What are you going for vacation?和Where are you doing on vaca where are you going和What are you doing的区别 Follow you,where what we are doing where are you doing where are you doing? where are you going where are you going?（ Where are you going? what are you doing. what you are doing what are you doing
