Invite your students to go down the memory lane of their lives, by using a world map, or personal travel pictures. Explain to them that you have had a very interesting life, telling them of places you have traveled to, and things you have done. Then elicit the present perfect simple from them as you continue to feed it. Drill the form before moving on. Here are some examples:
Teacher (T): Have you traveled around the world?
Student (S) No, I haven’t.
T - Have you visited New York?
S - Yes, I have.
Move on now to “Have you ever….?
T - Have you ever lived in India?
S - No, I haven’t.
T - Have you ever surfed in Florida?
S - Yes, I have.
Now, have your students work in pairs and either supply them with ideas, or have them experiment at asking their own questions.
Next you need to use variations on the examples which will ensure negative answers, and encourage weaving among the students.
T – Have you ever lived in an igloo?
S – No, I’ve never lived in an igloo
T- Has she ever walked across Africa?
S - I don’t know.
This student will then ask the student referred to: ‘Have you ever walked across Africa’?
To which the student replies: ‘No, I’ve never walked across Africa’.
Now you can introduce ‘been’
T - Have you ever been to Iceland?
S - No, I haven’t.
T - Where have you been?
S - I’ve been to Paris.
