是feel happy还是 feel happiness?请从语法角度解释,

答：feel happy是对的.因为feel可以作系动词,后跟形容词作表语如：I feel hungry.我感到饿了.
判断一个词是不是系动词,就是用be动词的适当形式去代规它,如果句子仍成立,则是.如这里,我们可以说：I am hungry.我饿了.
feel 也可以作及物动词,表示“触摸”,后跟实体名词,如：feel one's nose 摸某人的鼻子.feel one's pulse.号脉.但是happiness幸福是个抽象的东西,是无法用手去触摸的,所以feel happiness,除非诗歌,是一个不常见的动宾搭配.如果你想表达“我感到幸福”的话,则是错误的.
