or you could add an adjective and write:

Try to add adjectives to the nouns in the subject of your sentence and add them as a blog comment.
 
In a sentence there is a subject and then the action (verb) that the subject does, or something about the subject.
e.g. The dog barks.
The dog is the subject and the action is barks.
or The dog
is cuddly.
Again the dog is the subject and is cuddly tells us about the dog.

Remember that a sentences begins with a capital and ends in a full stop.
