例句:A dog is not considered a good dog because he is a good barker. A man is not considered a good man because he is a good talker.
句意:一条狗,不会只会因为会叫就被认定是一条好狗;一个人,不会只因为会说就被认定是一个好人。
如果把not放在because前,则句子变成:
A dog is considered a good dog not because he is a good barker. A man is considered a good man not because he is a good talker.
