由“what”引导的感叹句：修饰名词（被强调部分），
单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词
前不用冠词。句子的结构是： what+(a/an)+adj.+n.+主语+谓语. 由 what 引导的感叹句，其句子结构可分为以下三种：
1.“ What + a/an ＋形容词＋可数名词单数＋主语＋谓语！”。如：
What a nice present it is! 它是一件多么好的礼物啊！
What an interesting book it is! 它是一本多么有趣的书啊！
2. “ What ＋形容词＋可数名词复数＋主语＋谓语！”。如：

3：“ What ＋形容词＋不可数名词＋主语＋谓语！”。如：
What fine weather it is today! 今天天气多好啊！
What important news it is! 多重要的新闻啊！由“how”引导的感叹句：“how”意为“多么”，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，句子的结构是： How+adj.（adv.）+主语+谓语. 1. How ＋形容词 / 副词＋主语＋谓语！”。如：

由 what 引导的感叹句与由 how 引导的感叹句有时可以转换，但句中部分单词的顺序要有所变化。
How beautiful a girl she is! ＝ What a beautiful girl she is!
What delicious cakes these are!
＝ How delicious these cakes are!在表示同一意义时，英语感叹既可用“what”引导，
也可用“how”引导。如：
