\hfill\break 【分析】\\ 比较大小，可先与常见的常数$$0,1$$进行比较，然后根据函数的单调性进行比较大小\\ 【详解】\\ $$c={{\log }_{0.2}}0.3\textless{} {{\log }_{0.2}}0.2=1$$\\ $$a={{2}^{0.3}}\textgreater1$$\\ $$b={{3}^{0.4}}\textgreater1$$\\ 则有：$$a\textgreater c,b\textgreater c$$\\ $$a={{2}^{0.3}}\textless{} {{3}^{0.3}}\textless{} {{3}^{0.4}}$$\\ 故有：$$b\textgreater a\textgreater c$$\\ 故选：D 
已知$$a={{2}^{0.3}}$$，$$b={{3}^{0.4}}$$，$$c={{\log }_{0.2}}0.3$$，则（~~~~~~~）
Options:
(1) $$a\textgreater b\textgreater c$$ 
(2) $$b\textgreater c\textgreater a$$ 
(3) $$c\textgreater b\textgreater a$$ 
(4) $$b\textgreater a\textgreater c$$
