[EX Q]: Person1: Do you know how to go to the Fragrant Hills in Beijing ? I heard that they are very famous in China .
Person2:Yes . Especially in autumn , the red leaves of the maple trees make the whole mountain red .
Person1: That must be very beautiful .
Person2:Yes , it can make people feel as if they were in the land of fairies .
Person1: Really ? Have you ever been there ?
Person2:A couple of times .
Person1: Can you go there with me ? I'd like someone who is familiar with that area to go with me .
Person2:Sure . I'd be very glad to be your tour guide .

[EX Q]: Person1: Hi , excuse me . I am sorry to bug you , but do you know where the Royal Hotel is ?
Person2:Just a minute . I am as busy as a bee right now ... Ok , I am done . What can I do for you ?
Person1: Well , I seem to be a little bit lost here . I am worried that I ' ll never find my way . What's worse . I forgot my glasses and as blind as a bat now .
Person2:Well , keep you chin up ! I ' ll try to help you . Where are you going ?
Person1: I am trying to get to the Royal Hotel . Do you know where that is ?
Person2:Yes , no problem . You walk down this street . You turn left at the first intersection . Walk along that road , turn right at the corner . After that , you make a left-hand turn at the first traffic light . The Royal Hotel is on your right side .
Person1: Great . Are there any landmarks nearby ?
Person2:Yeah , I think so . I think the hotel is right across the street from a post office . It is as plain as the hump on a camel . You can't miss it .
Person1: Oh , that's good . I should be able to find it pretty easily then . Is that far from here ?
Person2:Yeah , it ' s gonna take you a while if you go by foot . I ' d say it's about a 30 - minute uphill walk . You have to be as strong as a lion to make it .
Person1: Oh , that will take too long and I am kind of in a hurry . Can I take a bus there ?
Person2:Well , you could take a bus there , but you would have to transfer buses twice . A taxi would probably be a lot quicker .
Person1: All right . I guess I'll take a taxi then . How long will it take by taxi ?
Person2:Not too long . It should take about ten mins by taxi .
Person1: Cool , thanks .
Person2:You are welcome .
