FAQs:
The Present Perfect Tense is used to describe actions completed in the past that are relevant to the present. Example: She has completed her homework. It emphasizes the connection between past actions and now.
It is formed using the auxiliary verbs “have” or “has” with the past participle form of the main verb.
“Have” is used with plural subjects (e.g., I, you, we, they), while “has” is used with singular subjects (e.g., he, she, it).
Ever, never, just, already, yet, since, for, recently, lately.
It’s generally better to avoid specific time expressions like “yesterday” or “last year” with the present perfect tense, as it is more suited for unspecific time references.
The simple past tense is used for actions with a specific time in the past, while the present perfect tense emphasizes actions with a connection to the present, even if the exact timing is not specified.
Look for has/have followed by a past participle (e.g., done, seen, written). Example: They have visited the museum.
