It is a tall tree.They are working very hard.It is very nice to see you.

问题描述:

It is a tall tree.They are working very hard.It is very nice to see you.
帮我改下上面三个句子的感叹句,顺便教我怎么改感叹句.

How tall the tree is!/What a tall tree (it is)!
How hard they are working!
How nice to see you!
How 突出的是形容词或副词,而What 突出的是名词.
