人模狗样

bié kàn tā kàn zhe rén mú gǒu yàng de qí shí yī dù zi huài shuǐ

别看他看着人模狗样的，其实一肚子坏水。

Despite his decent appearance, he is evil out and out.

lián tā yě rén mú gǒu yàng de lái chū xí wǔ huì le

连他也人模狗样地来出席舞会了。

Even a guy like him comes to the party, dressed as if he were a gentleman.

yīn wèi nǐ bù huì rén mú gǒu yàng de jì lǐng dài huò lǐ mào de xiào

因为你不会人模狗样地系领带或礼貌地笑。

Because you don't hide what you are behind a tie and a snappy smile.
