what后接名词how后接形容词感叹句一般是用来表示说话时的喜悦、惊讶等情感.英语感叹句常用"what"和"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+(itis).如:①Whataclevergirlsheis!多么聪明的姑娘呀!②Whataninterestingstoryitis!多么有趣的故事呀!③Whatgoodchildrentheyare!他们是多么好的孩子呀!④Whatbeautifulflowerstheyare!多么漂亮的花呀!⑤Whatdeliciousfooditis!多么有味的食物呀!⑥Whatheavysnowitis!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+(itis).如:①Howcolditistoday!今天多么冷呀!②Hownicethepicturesare!多么漂亮的图画呀!③Howhappytheylook!他们显得多么高兴呀!④Howwellshesings!她唱得多好呀!⑤Howhardtheyareworkingnow!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:①Whatahotdayitis!Howhotthedayis!多么热的天气呀!②Whattallbuildingstheyare!Howtallthebuildingsare!多么高的楼房呀!③Whatbadweatheritis!Howbadtheweatheris!多么糟糕的天气呀!④Whatbrightsunshineitis!Howbrightthesunshineis!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:①Whatafineday!多么晴朗的天呀!②Whatanhonestboy!多么诚实的孩子呀!③Whatredapples!多么红的苹果呀!④Howcool!好凉快呀!⑤Howwonderful!精彩极了!由what,how引导的感叹句的构成形式、用法及区别感叹句是表示喜、怒、哀、乐以及惊异等感情的句子.句末用感叹号“!”,读时用降调,感叹句往往由what或how引导,what修饰名词,how修饰形容词,副词或动词.1.what引导的感叹句:(1)what+a/an+形容词+单数可数名词+陈述句(主语+谓语)Whatabeautifulcityitis!Whataninterestingstoryshetold!(2)what+形容词+复数可数名词/不可数名词+陈述句(主语+谓语)Whatexpensivewatchestheyare!Whatterribleweatheritis!2.How引导的感叹句:(1)How+形容词/副词+陈述句(主语+谓语)Howcolditis!Howhardheworks!(2)How+陈述句(主语+谓语)Howheloveshisson!HowImissyou!(3)How+形容词+a/an+单数可数名词+陈述句(主语+谓语)Howtallatreeitis!(4)上述两种感叹句可以互相转换.例如:Whatacleverboyheis!→Howclevertheboyis!Whatacolddayitis!→Howcolditis!
