Hi, I'm doing a course on line but the homework doesn't have a review so if somebody can correct this sentences for me would be perfect.

Practice using the present perfect tense. Write two questions with answers and two statements.

Questions

1. A: Where have you gone today?

B: I have gone to the park.

2. A: Have you ever swum in Yaguarcocha?

B: Yes, I have. I have swum in Yaguarcocha once with my classmates.

Statements

1. My mother has cooked for me today

2. Andrea has not traveled to Quito.
