When a question is a “Yes/No” question, noun clauses begin with either “if” or “whether”. Let’s practice writing sentences both ways. Also, the phrase “or not” is often added at the end of the sentence.
For answers 1 to 12, use “if” in your answer.
1. Excuse me. Is there a park near here?
2. Did Mary buy her cell phone online?
3. Are the vegetables at Whole Foods expensive?
4. Does this camera work?
5. Do the teachers have a meeting every week?

9. Has the plane to Chicago left yet?
10. Is Lydia going to be my nurse?
11. Did a man in a green hat just walk by here?
12. Did my sister leave a message?
For questions 13 to 25, use “whether” in your answer
