“what”和“how”引导的感叹句
感叹句一般是用来表示说话时的喜悦、惊讶等强烈的情感。
中学要求掌握的主要英语感叹句常用"what"和"how"引导。"what"和"how"与所修饰的词（被强调部分）置于句首，其它部分用陈述句语序。
一、"what"引导的感叹句。
"what"意为"多么"用作定语，修饰名词短语（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。
He is a clever boy.
→ What a clever boy (he is)! （ 他是）多么聪明的男孩啊！
They are beautiful flowers.
→What beautiful flowers (they are)！（它们是）多么漂亮的花啊！
It is fine weather.
→ What fine weather (it is)! 多么好的天气啊！
这类句子的结构形式是：What + (a/an)+形容词+名词 （+主语+谓语）！
“(a/an)+形容词+名词”也就是名词短语，主语和谓语常常可以同时省略。
二、"how"引导的感叹句。
"how"意为"多么"，用作状语，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。
The boy is clever.
→ How clever (the boy is)! （这个男孩）多么聪明啊！/ 好聪明啊！
The girl is beautiful.
→How beautiful( the girl is)! （这女孩）多么漂亮啊！/ 好漂亮啊！
They are working hard now.
→How hard they are working now! 他们干得多么起劲呀！
这类句子的结构形式是：How + 形容词 / 副词 （+主语+谓语）！
通常两种句型有时可以相互转换： she is a pretty girl.
How pretty the girl is! = What a pretty girl she is!
