1. Parents are often upset when their children praise the homes of their friends and regard it as a slur on their own cooking, or cleaning, or furniture, and often are foolish enough to let the adolescents see that they are annoyed.
    当家长听到孩子赞扬自己朋友的家时，总感到不安，认为孩子在嫌弃自家的饭菜、卫生、或家具，而且愚蠢地让孩子看出自己的烦恼。

2. It´s a slur on his good name.
    这是对他好名声的诽谤.
