however表让步，译为"无论如何"
However we adopt healthcare reform, it isn't going to save major amounts of money.
不管我们采取何种医疗改革措施，都省不下太多钱。
误区提示：however可以表示转折，译为"然而；不过；仍然"但是这时为副词词性，而并非连词。 [1] 
例句：
This was not an easy decision. It is, however, a decision that we feel is dictated by our duty...
这很难抉择。不过，我们觉得自己有义务作出决定。
