高分求一小段英文的阅读理解,要有原因解释.

答案是：A.
原文是——The view that a happy man lives well and fares well fits in with our definition:for we have all but defined happiness as a kind of good life and well-being.
认为,一个幸福的人的生活很好,很好符合我们的定义：我们都把幸福定义为一种良好的生活和幸福.
The author`s definition of happiness is related to the definition of good in that
作者`对幸福的定义是,好的相关定义
A.living a good life will bring happiness
一个良好的居住生活带来的快乐
B.happiness is the same as goodness
幸福是一样善良
C.all things that creat happiness are good thing.
所有的东西,创造幸福是件好事
for we have all but
我们都只是
所以,从语义上判断是A.“for we have all but defined happiness as a kind of good life and well-being”=“一种良好的生活和幸福”.
