Zorluk: KolayVerbs, Tenses, and Aspect

Which verb form correctly completes the blank in the sentence below?

Cevap:Mrs. Adeleke 【has taught】 English language at the community secondary school since 2015.

Cevap

The correct form is 'has taught' or 'has been teaching'.
The preposition 'since' denotes the starting point of a situation that extends up to the present. The present perfect form ('has taught') or present perfect continuous form ('has been teaching') accurately expresses this ongoing temporal relationship with the singular subject.

Adım Adım Çözüm

1
Identify the time adverbial phrase in the sentence.
The phrase 'since 2015' marks an action that originated in the past and continues into the present.
Time markers introduced by 'since' require a verb in the present perfect or present perfect continuous tense.
2
Select the verb form matching the third-person singular subject.
'has taught' (or 'has been teaching') agrees in person and number with 'Mrs. Adeleke'.
The singular auxiliary verb 'has' combined with the past participle 'taught' correctly establishes the present perfect aspect.
