To convert assertive (or declarative) sentences into exclamatory sentences, we generally express the strong emotions or feelings conveyed within the assertive sentence using words such as 'how' or 'what', and adjust the structure accordingly to fit an exclamatory format. The exclamation mark (!) at the end of the sentence is crucial to indicate the emotion.
Here's how you can transform each of the given sentences:
You are very slow. Exclamatory: How slow you are!
She is very beautiful. Exclamatory: How beautiful she is!
They are very happy here. Exclamatory: How happy they are here!
It was a very marvelous sight. Exclamatory: What a marvelous sight it was!
This is a very adventurous movie. Exclamatory: What an adventurous movie this is!
I am very fortunate. Exclamatory: How fortunate I am!
It was a very difficult puzzle. Exclamatory: What a difficult puzzle it was!
It was a very hot day. Exclamatory: What a hot day it was!
The transformation of assertive to exclamatory sentences is often a matter of adjusting word order and adding an expressive word to better convey the sentiment. This method enhances the emotional impact of the sentence, providing a more vivid expression of feelings.
