感嘆句一般是用來表示說話時的喜悅、驚訝等強烈的情感。
中學要求掌握的主要英語感嘆句常用"what"和"how"引導。"what"和"how"與所修飾的詞（被強調部分）置於句首，其它部分用陳述句語序。
一、"what"引導的感嘆句。
"what"意為"多麼"用作定語，修飾名詞短語（被強調部分），單數可數名詞前要加不定冠詞a/an,複數可數名詞或不可數名詞前不用冠詞。
He is a clever boy.
→ What a clever boy (he is)! （ 他是）多麼聰明的男孩啊！
They are beautiful flowers.
→What beautiful flowers (they are)！（它們是）多麼漂亮的花啊！
It is fine weather.
→ What fine weather (it is)! 多麼好的天氣啊！
這類句子的結構形式是：What + (a/an)+形容詞+名詞 （+主語+謂語）！
「(a/an)+形容詞+名詞」也就是名詞短語，主語和謂語常常可以同時省略。
二、"how"引導的感嘆句。
"how"意為"多麼"，用作狀語，修飾形容詞或副詞（被強調部分）。如果修飾形容詞，
則句中的謂語動詞用系動詞；如果how修飾副詞，則句中的謂語動詞用行為動詞。
The boy is clever.
→ How clever (the boy is)! （這個男孩）多麼聰明啊！/ 好聰明啊！
The girl is beautiful.
→How beautiful( the girl is)! （這女孩）多麼漂亮啊！/ 好漂亮啊！
They are working hard now.
→How hard they are working now! 他們幹得多麼起勁呀！
這類句子的結構形式是：How + 形容詞 / 副詞 （+主語+謂語）！
通常兩種句型有時可以相互轉換： she is a pretty girl.
How pretty the girl is! = What a pretty girl she is!
