[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 .

[EX Q]: Person1: Ok , I ' Ve got an up-to-day map . Let ' s check the route from here to the airport .
Person2:Where are we ? Oh , here we are . So we drive to the A120 and turn left .
Person1: No , we turn right . Remember that we are coming from this direction .
Person2:Oh yes ! Sorry ! Then we drive to the M11 motorway .
Person1: How far is that ?
Person2:It ' s only seven miles . We turn left to join the motorway and drive south .
Person1: According to the map , we get off the M11 at the second junction and join the M25 . That ' s the motorway that goes around the edge of London .
Person2:That ' s another 15 miles , so that ' s 22 miles total so far .
Person1: Then we drive west on the M25 . we must be careful to turn in the right direction !
Person2:Then we drive on the M25 . it turns south . When we reach exit 15 , we turn left and go west along the M4 .
Person1: Then we take the first Heathrow Airport . What ' s the total distance ?
Person2:The journey around the M25 is 33 miles and then 3 extra miles to get to the airport . So how many miles is that together ?
Person1: 22 miles to the M25 , 33 miles on the M25 , and 3 after that . That ' s a total of 58 miles , isn ' t it ?
Person2:It shouldn ' t take us very long to cover that distance . Remember that we can go quite fast on the motor way .
Person1: We can only go fast on the motor ways if there isn ' t much traffic . I think we should allow ourselves plenty of time to get there . Being early is much better than being late .
