Question

Change the following sentence by replacing the main verb with a noun:
He teaches science in class.

• A. He is our science teacher.
• B. He is teaching science.
• C. In class, he teaches science.
• D. No change.

Answer 1

Answer: (A)

In the given sentence, the main verb is "teaches" (teach).

In option B, teaching is the present continuous tense of the verb "teach". It is still a verb or action. Therefore, it is incorrect. C is incorrect as well since "teaches" is the same as the verb in the given sentence. It is an action and not a noun.

A noun is a word or phrase used to identify any class of people (doctor, lawyer, etc), places or things, or to name a particular one of these (proper noun).

Some verbs can be changed into noun by adding "-er" at the end. For example, the verb "play" becomes the noun "player". The noun form of the verb "teach" is "teacher". In option A teacher is a noun as it is a label used to identify the person "he" (the person is a "science teacher"). Therefore option A is correct.
