a (an) +形容词+ 可数名词单数(+主语 +谓语)!
形容词+ 可数名词复数形式(+主语+谓语)!
形容词+ 不可数名词(+主语 +谓语)!

Have a try!
怎样判断用what or how
Work out the rules
How+ adj./adv. (+主语+谓语) !
What+(a/an)+adj.+n.(+主语+谓语) !
Skill 1
hat
只有形容词或副词直接用how
有a或an用what
找准名词，判断名词前面是否有the，her等限定词，若有则为how；
如无则为what ，然后再判断这个名词是否可数，可数则在what后加a或an。
Skill 2
1.______a heavy box it is !
2. ______heavy the box is !
3. _____ wonderful the film is !
4. ______ a wonderful film it is!
5 . ______beautiful the flowers are!
6.______beautiful flowers they are!.
What
How

What
Use ‘What’ or ‘How’
eg: 1. How interesting the boy is !
_____ _____ interesting boy he is！
What
Think about: What 与How 同义句转换
an
解题思路：
首先,要记得:感叹句由How或者What引导，
其次,要分析:如果所给题由How引导，那它的同义句就应该由What引导;
反之一样，即：如果所给题由What引导,那它的同义句就应该由How引导
最后，如果是可数名词单数就在形容词前加上冠词a或者an ,否则不用。
1. What a pretty girl she is!
_______ _______ the girl is!
2. How difficult the questions are!
_________ ________ ________ they are.
3. How big the factory is!
_______ _______ big factory _____ ____!
How pretty
What difficult questions
