Auxiliary verbs are functional words used to express tense...
Auxiliary verbs are functional words used to express tense, mood, or voice in a sentence, working alongside main verbs. Understanding their different roles is crucial for accurate sentence construction. Mark the CORRECT alternative.
A
The auxiliary verb "have" is used to form the perfect tenses (present perfect, past perfect) and is also used in the passive voice formation when combined with the past participle of "be".
B
The auxiliary verb "be" must be omitted in interrogative sentences of the present continuous tense to avoid a double marking of the progressive aspect in the verbal phrase.
C
The auxiliary "do" is required to form negative and interrogative sentences in all English tenses, including sentences where the main verb is a modal verb like "should" or "might".
D
In the sentence "She has a car", the word "has" functions primarily as an auxiliary verb, indicating that the action of possessing is currently happening in the simple present tense.
E
The auxiliary "do" is used with the verb "to be" in negative sentences of the simple present, such as "He does not be a student", following the standard rule for all main verbs.
