感叹句感叹句是表达喜、怒、哀、乐以及惊奇、惊讶等强烈感情的句子。
感叹句通常由what 或 how 引导。
"what"和"how"与所修饰的词置于句首，其它部分用陈述句语序。
一、由"what"引导的感叹句："what"意为"多么"用作定语，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。
这类句子的结构形式是： what+(a/an)+adj.+n.+主语+谓语.如：① What a clever girl she is! 多么聪明的姑娘呀！② What an interesting story it is! 多么有趣的故事呀！③ What good children they are! 他们是多么好的孩子呀！④ What beautiful flowers they are! 多么漂亮的花呀！⑤ What delicious food it is! 多么有味的食物呀！⑥ What heavy snow it is! 多么大的雪呀！二、由"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，这类句子的结构形式是：How+adj.（adv.）+主语+谓语.如：① How cold it is today! 今天多么冷呀！② How nice the pictures ar e! 多么漂亮的图画呀！③ How happy they look! 他们显得多么高兴呀！④ How well she sings! 她唱得多好呀！⑤ How hard they are working now! 他们干得多么起劲呀！三、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：① What a hot day it is!How hot the day is !多么热的天气呀！② What tall buildings they are!How tall the buildings are!多么高的楼房呀！③ What bad weather it is!How bad the weather is!多么糟糕的天气呀！④ What bright sunshine it is!How bright the sunshine is!多么明亮的阳光呀！四、感叹句在表示激动强烈的感情时，口语中常常采用省略句，其后面的主语和谓语往往略去不讲。
如：① What a fine day! 多么晴朗的天呀！② What an honest boy! 多么诚实的孩子呀！③ What red apples! 多么红的苹果呀！④ How cool! 好凉快呀！⑤ How wonderful! 精彩极了！一、由 what 引导的感叹句，其句子结构可分为以下三种：1. 可用句型：“ 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. 可用句型：“ What ＋形容词＋可数名词复数＋主语＋谓语！”。
如：What beautiful flowers they are! 多么漂亮的花啊！What good children they are! 他们是多么好的孩子啊！3. 可用句型：“ 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！二、由 how 引导的感叹句，其句子结构也分为三种：1. 可用句型：“ How ＋形容词 / 副词＋主语＋谓语！”。
如：How careful she is! 她多么细心啊！How fast he runs! 他跑得多快啊！2. 可用句型：“ How ＋形容词＋ a/an ＋可数名词单数＋主语＋谓语！”。
如： How beautiful a girl she is! 她是个多么漂亮的姑娘啊！3. 可用句型：“ How ＋主语＋谓语！”。
如：How time flies! 光阴似箭！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。
如：How beautiful a girl she is! ＝ What a beautiful girl she is!What delicious cakes these are! ＝ How delicious these cakes are!三、有时感叹句也可以由一个单词、词组、祈使句、陈述句等构成。
如： Good idea! （好主意！） wonderful! （太精彩了！） Thank goodness! （谢天谢地！）1) 就用what a/an；是不可数名词或可数名词复数，只用what。
2a/an/the/my/your/this/that/Tom’s等等乱七八糟的东西，想都不用想，直接用how就OK了。
如：例句1：What a boy he is! 他是个多么好的男孩啊！/ \单数名词例句2：boys they are! 他们是多么好的男孩啊！/ \复数名词例句3：What weather it is! 多么冷的天气啊！/ \不可数名词例句4：How the boy is! 这男孩多好啊！/ \乱糟糟★★★若没有形容词，而出现副词或是句子，直接用how.例：How well he plays the guitar! 他吉他弹得多好啊！/副词（what不可以修饰副词，看到副词直接用how）How time flies!How fast Liu Xiang runs打油诗一首: 感叹句往后看就用what a或what an形后若是不可数或名复数只用what就可以形容词后乱糟糟只写how就OK了专项练习一、填入适当的词完成下列感叹句。
