Negative in red letters
(Contractions in parentheses)
The present perfect is a verb form to describe something that happened at a non-specific time (you don't say what time) in the past or that started in the past and continues into the present.
I have visited the White House. (It happened at a non-specific time in the past.)
I have studied English for three years. (It started in the past and continues into the present.)
We form the present perfect with have or has and a participle.
I have finished the project.
She has worked at that company since 1990.
The word have in the present perfect is an auxiliar verb.* Like with other auxiliary verbs, we can add "not" to the auxiliary verb to form the negative and we can put the auxiliary verb at the beginning to form a question.
*The verb have is not an auxiliary verb when it is used to talk about possession, as in "I have a car." It would be "I don't have a car" in the negative.
Examples of the Negative
I have not finished the project.
(or the contraction)
I haven't finished the project.
She has not worked at that company.
(or the contraction)
She hasn't worked at that company.
To form a question, we use have or has, the subject, and then the partciple.
Examples of Questions
Have you finished the project?
Has she worked at that company?
We can also form a contraction of have or has when we use the present perfect (but not when have or has is used for possession, as in "I have a car.") In the present perfect have is contracted to 've and has is contracted to 's.
I've finished the project.
She's worked at that company since 1990.
We use the participle form of the verb with the present perfect. Usually we form participles by adding -ed to the verb (like when we form the past tense).
However, there are many irregular participles. Sometimes the participle is the same as the past tense form and sometimes it is different.
Examples of Irregular Participles Verb Participle be been see seen go gone do done buy bought
