回答1)judge by/from...根据...来判断(两者通用的);
回答2)stick to (doing) sth坚持做某事
例子1:We can judge from the attitude(态度) of the owner if(是否) they are serious about(认真对待) fixing(修理) it.
例子:2We should stick to our principles(原则).我在字典上查的时候，是看到过judge ……on的丫~1)Are you believe in yourself or believe in everybody 's else judge on you? 你是相信你自己还是别人对你的判断呢?2)So this is why you`re supposed to judge people on personality. 难怪人家说要重视内在美那什么时候用judge on什么时候用judge from/by呢？
