Harry: Hi Jerry. The school year is almost over. Do you have 1for the summer holidays?
Jerry: I'm planning on sleeping all day, every day!
Harry: Oh, come on Jerry, you must be kidding.
Jerry: Yeah! Actually, I'm going to go to the Grand Canyon.
Harry: Really?
Jerry: Exactly! It won't be too crowded. I enjoyed my trip to the Grand Canyon last year. I think the Grand Canyon is one of America's main 2.
Harry: But won't it be 3 in the summer?
Jerry: No, according to one of my friends, it's very cool in the summer.
Harry: Well, that 4. I wouldn't mind going. But… still, I wonder... is there anything 5 in the Grand Canyon?
Jerry: Sure! For one thing, there's the beautiful natural scenery and a lot of things to do. I can go hiking in the hills.
Harry: Gee, when you describe it like that, it sounds really interesting!
