A great summer vacation
just returned from the greatest summer vacation! It was so fantastic, I never wanted it to end. I spent
eight days in Paris, France. My best friends, Henry and Steve, went with me. We had a beautiful hotel room
in the Latin Quarter, and it wasn't even expensive. We had a balcony with a wonderful view. We visited
many famous tourist places. My favorite was the Louvre, a well-known museum. I was always interested in
art, so that was a special treat for me. The museum is so huge, you could spend weeks there. Henry got
tired walking around the museum and said "Enough! I need to take a break and rest." We took lots of
breaks and sat in cafes along the river Seine. The French food we ate was delicious. The wines were tasty,
too. Steve's favorite part of the vacation was the hotel breakfast. He said he would be happy if he could eat
croissants like those forever. We had so much fun that we're already talking about our next vacation!
Task 2. Read and choose.
1) What city did they go to for their summer vacation?
a) Lyon
