输出：

Client: I can work just fine with the Target objects:
Target: The default target's behavior.

Client: The Adapte class has a weird interface. See, I don't understand it:
Adaptee: .eetpadA eht fo roivaheb laicepS

Client: But I can work with it via the Adapter:
Adapter: (TRANSLATED) Special behavior of the Adaptee.
