Final answer:
The verb "lifted" in the sentence is an action verb which conveys a physical action performed by the subject "she." Action verbs are crucial for conveying what the subject is doing in a sentence, as they show physical or mental actions.
Step-by-step explanation:
The type of verb used in the sentence "She lifted a heavy bag at the airport." is an action verb. An action verb expresses physical or mental action. In this sentence, "lifted" is the action verb indicating what the subject did. The subject of the sentence is "she" which refers to an unspecified female person involved in the action. The word "lifted" describes the action of raising or moving something to a higher position or level.
Verbs are essential components of sentences as they express the action that the subject is performing. Other examples include "gripped" where the subject exerts a firm hold, and "launched" for sudden movement. Referring to locations or directions such as "Baggage claim is over there," the verbs used also describe actions or states of being.
In Example 1, "Robert dropped the ball," "dropped" is the action verb as well. Similarly, the phrase "Her watch and wallet were stolen," "were stolen" is a past passive construction indicating an action that happened to the subject's possessions.
