形容“做事要抓住事物的重点”的成语有哪些
感叹句是用来表达说话者说话时的惊异、喜悦、愤怒、气愤等思想感情的句子。
其结构常由感叹词“What(How)+感叹的部分+主语+谓语
”构成。
读时一般用降调。
主要有以下两大句型： 一、由感叹词what引导的感叹句。
what修饰名词或名词短语，有以下两种形式： 1. What+a(an)+（形容词）+单数可数名词+主语+谓语
如： What an apple this is! What a fine day it is! 2. What+(形容词）+可数名词复数或不可数名词+主语+谓语
What kind women they are! What nice music it is! 二、由How引导的感叹句。
how用来修饰形容词、副词或动词。
其结构是：How+形容词（副词）+主语+谓语
How hard the worker are working! How clever the girl is! How quickly the boy is writing! 注意：当how修饰动词时，动词不跟着感叹词提到主语之前。
How the runner runs! 三、what与how引导的感叹句，一般情况下可以相互转换，转换后意义不变。
如： What an interesting story it is!==How interesting the story is! what a beautiful bulding it is!==How beautiful the building is! 四、在口语中，感叹句的主语和谓语常常省略。
如： What a nice present!（省略it is） How disappointed!（省略she is或其它可作本句主、谓的词语）感叹句的句型特点及做法： 一、如何快速掌握感叹句
学会分析五种基本句型的句子成分是快速掌握感叹句的关键，陈述句变感叹句实际上就是句子成分位置的移动。
例1 She is smiling sweetly. →How sweetly she is smiling!（移动状语） 二、哪些句子成分可能会移动位置
通过对句子成分的分析我们就可以确定哪个句子成分需要挪动位置，一般说来含有形容词的名词短语、形容词短语和副词短语需要变动位置。
位置可能会变动的句子成分：宾语、表语和状语。
例2 Mr Turner told us a funny story. →What a funny story Mr Turner told us!（移动宾语含有形容词的名词短语） 三、如何确定使用what还是使用how
当我们做句型变换或选择题时需要自己确定到底是用what还是用how，一般可以这样来确定：位于主语之前的是名词短语时用what，是形容词或副词短语时用how。
但这种格式例外: how + adj. + a\\\/ an + N 例3 What a cool bike you are riding!（a cool bike 名词短语） 例 4 How fast he is riding!（fast 副词） 例 5 How cool a bike you are riding!（how + adj. + a\\\/ an +N） 四、如何判断是否使用冠词、使用什么样的冠词
名词的复数形式和不可数名词之前不使用冠词，以元音音素开头的词语之前用an，以辅音音素开头的词语之前用a。
例6 What beautiful sunshine it is today!（sunshine 不可数名词） 例7 What a useful book this is!（useful 以辅音音素开头） 例8 What an old house that is!（old 以元音音素开头） 五、感叹句有哪几种格式
简单地说是两型七式：两种句型是以what开头的句型和以how开头的句型，七种格式是 ① what + a + adj. + N+ S +V ② what + an + adj. +N +S +V ③ what + adj. + N（不可数） + S +V ④ what + adj. + N（可数名词复数形式）+ S+V ⑤ how + adj.+ S +V ⑥ how + adv. + S + V ⑦ how + adj. + a\\\/ an + N + S+V 例 What exciting news it is!（what + adj. + N（不可数名词形式）+ S + V结构） 例9 What good teachers they are!（what + adj. + N（可数名词复数形式）+ S+V结构） 例10 How warmly they are discussing!（how + adv. + S + V结构） 例11 How beautiful a picture it is
（how + adj. + a\\\/ an + N + S + V 结构） 六、以what开头的句型和以how开头的句型怎样进行转换
这两种句型之间的转换主要是指以下两种情况而言的: ⒈含有a\\\/ an + adj. + N 结构的句子方法是把形容词单独抽出来放在名词短语的前面和how搭配使用。
⒉名词短语作主语而表语是形容词的句子方法是把主语当作a\\\/ an + adj. + N结构的中心名词而用人称代词充当主语。
例12 What an expensive glass he broke! →How expensive a glass he broke! 例13 How beautiful the birds are! →what beautiful birds they are! （说明：N代表名词，未特别说明者代表可数名词的单数形式，S代表主语，V代表动词） 七、在感叹句中哪些词语常常省略
常常省略的是充当主语的人称代词和动词be。
例14 What a naughty boy!（省略了he is
