| — Can you help me? — Sure, what's the problem? — 1 — Well, how about San Francisco? We went there last year and had a great time. — 2 — Well, there is Golden Gate Bridge of course, and Golden Gate Park. It's a really big park. You can go for long walks or take a rest in the Japanese Tea Garden. It's beautiful there. — 3 — There is also a place called Fisherman's Wharf. That's really popular with tourists. There are lots of shops, cafes and restaurants. And from there you can go on a boat trip to Alcatraz. You know, it's a small but very beautiful island. — 4 — No, you can't stay on the island; there aren't any hotels. You can only go for the day. I think I've still got a book about San Francisco. I can lend it to you. — 5
