What + 形容詞 + 不可數(shù)名詞 (+ 主語(yǔ) + 動(dòng)詞）!
What delicious milk it is!
How + 形容詞/副詞 (+ 主語(yǔ) + 動(dòng)詞）!
How beautiful this girl is!
以上有點(diǎn)麻煩,簡(jiǎn)單記：
把感嘆句從后面把主語(yǔ)和謂語(yǔ)（句子）挑出,然后看前面的感嘆部分,若有名詞,就用what；若無(wú),就用how.但是注意單數(shù)時(shí)候：what a careful student she is!= How careful a student sh is!
練習(xí)：
_____nice it is today!
_____ a nice day it is today!
_____ ugly animals they are!
Keys:How; What:what
What a big box it is!== How big the box is!
What nice weather it is!== How nice the weather is!
What clean rooms they are!== How clean the rooms are!
