Answer :
In the given sentences, we need to identify and circle the nouns.
A noun is a word that names a person, place, thing, or idea. Let's look at each sentence one by one:
The box is empty.
- Here, the noun is 'box' because it represents a thing.
Monkeys are jumping on the trees.
- The nouns in this sentence are 'monkeys' and 'trees' because they are both things, specifically animals and plants, respectively.
My father is a doctor.
- The nouns are 'father' and 'doctor'. They both represent people.
Sheema is a pretty girl.
- 'Sheema' is a noun because it is a proper name, and 'girl' is a noun because it refers to a person.
Switch on the television.
- The noun here is 'television' as it is a thing.
Nouns are essential parts of sentences because they can be the subject of a verb or the object of a verb or preposition. They help us identify what or who we are talking about in each sentence.
