2. I have seen the Eiffel tower four times.
3. I have not broken a bone before.
Asking Questions
• You can use the present-perfect tense to ask a question such as: Have you ever seen an alien?
• Notice that the above question does not include a specified date/time.
• How might you respond to this question? (Think-Pair-Share)
• Appropriate answer: No, I have not seen an alien.
More Questions!

• Statement: I have seen a shooting star.
• Question: Have you seen a shooting star?
• What words have been rearranged in the sentences?
