English is very useful.(改为感叹句) _____ _____useful subject English is!

答案：填What a
即：What a useful subject English is!
翻译：英语是多么有用的一门学科呀!
解析：这是一个感叹句,下面看看感叹句的用法：
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!
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!
　　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!
　　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）
也就是说：what 感叹句修饰的中心词是名词,而how感叹句修饰的中心词是形容词,本句的中心词是subject,所以用what修饰,另外useful 虽然是元音字母u开头,但是发音却是辅音/j/开头,所以用what a
