well-known是一个复合形容词，由“副词 过去分词”构成。英语意思是known by a lot of people，汉语解释为“知名的”。但这个词是原级，它的比较级和最高级是什么呢？
有的同学看到后，马上会说，这是一个单词，比较级当然是more well-known，最高级是best well-known。其实这是不对的。
如果溯源，我们需要想一想well的比较级和最高级，由此得出，well-known的比较级和最高级分别是better-known和best-known。
He was a better-known poet than his father. 他是比父亲还有名气的诗人。
He is better known for his film and TV work. 他更为著名的是影视作品。
She is one of the best-known singers of recent years. 他是近年来最有名的歌手之一。
This is probably their best-known song. 这一首很可能是他们最出名的歌曲。
