你說的多好的天氣
what great weather it is
由感嘆詞what引導(dǎo)的感嘆句.
　　what修飾名詞或名詞短語,有以下兩種形式：
　　1.What+a(an)+（形容詞）+單數(shù)可數(shù)名詞+主語+謂語!或是：What+名詞詞組+主語+謂語!如：
　　What an apple this is!What a fine day it is!
　　2.What+(形容詞）+可數(shù)名詞復(fù)數(shù)或不可數(shù)名詞+主語+謂語!
　　What kind women they are!What nice music it is!
　　由How引導(dǎo)的感嘆句.
　　how用來修飾形容詞、副詞或動詞.其結(jié)構(gòu)是：How+形容詞（副詞）+主語+謂語!
　　How hard the workers are working!
　　How clever the girl is!
　　How quickly the boy is writing!
　　注意：當(dāng)how修飾動詞時,動詞不跟著感嘆詞提到主語之前.
　　How the runner runs!
　　what與how引導(dǎo)的感嘆句,一般情況下可以相互轉(zhuǎn)換,轉(zhuǎn)換后意義不變.如：
　　What an interesting story it is!==How interesting the story is!
　　what a beautiful building it is!==How beautiful the building is!
　　在口語中,感嘆句的主語和謂語常常省略.如：
　　What a nice present!（省略it is）
How disappointed!（省略she is或其它可作本句主、謂的詞語）
