如果变成以How开头就直接说How good memory you have for English learning!
a saying一句名言,there is后面的名词一般加不定冠词作修饰.
practice泛指练习不用the,不可数,不用a
附:
1.How delicious food we have had!为什么是错的,要把how换成what?
看结构,How delicious food we have had!是病句,how是形容词性,不能引导delicious food,如果是用how,应为How delicious the food we have had!
How beautiful a picture it is!
How hot the day is!
为什么第2句最后的is前没有it?
这里的it可以省略.
