Answer:

Step-by-step explanation:
Linking verbs are verbs that do not express actions, but conditions or states. Their function is to connect the subject of a sentence to a word that identifies or describe the subject. Examples of this type of verbs are all forms of the verb "to be" (like am, is, was, were) and the verbs "to become" and "to seem."
The verb to drive and to live, on the other hand, are action verbs.
Here are some examples of sentences with linking verbs:
She became mom at the age of sixteen.
Rose seems sad
William is excited about his promotion.
The winter scene was mysterious.
