Present Perfect exercises. Part3.

Rewrite the following sentences using the present perfect tense. To rewrite a sentence in the present perfect tense, you need to identify the subject, the main verb, and the object (if any). Then, you replace the main verb with its past participle form and add the auxiliary verb "have" or "has" before it, depending on the subject. Remember to make the necessary changes to the verb form, such as adding "-ed" or using the irregular past participle form, depending on the verb. Now, you can practice rewriting the sentences using the present perfect tense.
