「Beginner」step1 ：初级入门

    A ： Excuse me， can you tell me the way to Holton railway station？

    B ： Sure. It ‘s quite far from here. Don’t worry ， though. It
‘s not difficult to get there.

    A ： I think I‘m going in the wrong direction， aren ’t I ？

    B ： Yes. First ， you need to turn around. Do you remember passing
some traffic lights further up this road？

    A ： Yes， I do. They are about two miles away， right？

    B ： That ‘s right. Drive back to the traffic lights and turn right.
Follow the road for about a mile， until you see the plaza hotel. It’
s a really big hotel. You can ‘t miss it. Turn left at the hotel.

    A ： So ， right at the traffic lights two miles up the road， then
left at the plaza hotel ， a mile along that road. Got it.

    B ：Then you just go straight on until you see the station ahead of
you.

    A ：Ok. Got it. Thanks for your help.

    B ： No problem.

    「Intermediate」step2 ：中级进阶

    A ： Ok ， I‘ve got an up-to-date map. Let ’s check the route from
here to the airport.

    B ： Where are we ？ Oh ， here we are. So we drive to the A120 and
turn left.

    A ： No ， we turn right. Remember that we are coming from this direction.

    B ： Oh yes ！ Sorry！ Then we drive to the M11 motorway.

    A ： How far is that？

    B ： It ‘s only seven miles. We turn left to join the motorway and
drive south.

    A ： 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.

    B ： That ‘s another 15 miles， so that’s 22 miles total so far.

    A ： Then we drive west on the M25. We must be careful to turn in
the right direction ！

    B ： Then we drive on the M25. It turns south. When we reach exit
15， we turn left and go west along the M4.

    A ： Then we take the first right to Heathrow Airport. What ‘s the
total distance？

    B ： 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 ？

    A ： 22 miles to the M25， 33 miles on the M25， and 3 after that.
That‘s a total of 58 miles ， isn’t it？

    B ： It shouldn ‘t take us very long to cover that distance. Remember
that we can go quite fast on the motorways.

    A ： We can only go fast on the motorways 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.
