The present perfect tense in English is a past tense. However, it is different than the simple past. It is a past tense, but it connects with the present. Today I show you how to form the present perfect tense. I also show you how to ask and answer questions with it. Finally, I show you some ways that this tense is used. I also give you example sentences. In the next posting, I talk some special words that require you to use the present perfect. At the end, of course, there will be a download. The download will give you some common verbs that are irregular in the simple past and have irregular past participles.
The present perfect tense is not the simple present, and it is not the simple past. The simple past talks about an action that is completely finished. The present perfect talks about the past, but it connects to the present.
How do we form the present perfect tense?
The present perfect tense is easy to form. We use the simple present form of the verb to have. Then we add the past participle.
What is a past participle?
The past participle is a special verb form of the past. We never use it by itself. Instead, we use it with auxiliary verbs such as have. Most of the time it is easy to know what the past participle of a verb is. If the simple past is regular (it ends in ed ), the past participle is exactly the same. For example, the simple past of work is worked. The past participle of work is also worked. Of course some verbs have irregular forms in the simple past. If a verb is irregular in the simple past, the past participle is also irregular. For example, the simple past of eat is ate. The past participle is eaten. You will have to learn the irregular forms, but the download at the end will help you.
The present perfect tense is the affirmative and negative.
To form the present perfect tense in the affirmative or negative, use the following formula:
subject + have/has (not, for negative) + past participle
You have worked. You haven’t worked.
He/She/It has worked. He/She/It hasn’t worked.
We have worked. We haven’t worked.
They have worked. They haven’t worked.
Asking a question in the present perfect tense.
To ask a yes/no question in the present perfect tense, use the following structure:
have/has + subject + past participle
To ask a wh question, use the yes/no structure, and put the wh in front.
Wh + have/has + subject + past participle
Where have you worked in the past three years? I have worked in two hospitals.
What has he done (past participle of do) to his jacket? He fell down and got it dirty.
