how good a boy he is 我不懂怎么写感叹句这个句子中的a boy是名词吧.那这个语法公式是什么?不是说hao加形容词后不能加名词吗

how clever a boy he is!how clever he is! ( )a good looking boy he is! He is a good boy.(感） He is a good boy.改为感叹句 改错：What good a boy he is! He is a good boy ( )shool 把句子改成What和How开头的感叹句：He is a good boy. he is a good boy改为感叹句how _ _ _ How a nice boy he is 改错 Steven is a good boy.he is born in 1997.改错还有How did Helen Keller learn to writing? I b()what he said.He is a good boy. 英语翻译( )good boy he is John is a good boy.He a( ) helps his classmates. He is as a good boy as Tim.为什么要用as a good boy as? he,a,is,good,boy连词成句 he is a good boy.改成一般疑问句怎么改? he is a good boy(改为一般疑问句) He is a good boy表语是什么吖
