题目内容：

beautiful high,clear voice
My textbook says:
the boy had a beautiful high,clear voice.
why not add a comma between the words beautiful and high?Is beautiful high a phrase?

优质解答

这是用一个形容词来形容另外两个形容词的现象.beautiful high 不是固定搭配.可以理解为the boy had a beautiful high ,beautiful clear voice.
句子意思为：这个男孩有漂亮的嗓音,又高,又清晰.
