听力原文:Presenter: Welcome to this latest lecture on living in London. Today,

we're going to look at transport and I'd like to start with the London underground

system—also called "the tube" because of the shape of the tunnels.

First, you need to learn your lines. There are 12 different lines, each with its Q11

own name, for example, the Piccadilly line, the Circle line. Each line is a different Q12

colour on the map of the underground system. You can find the map

in the ticket hall at each underground station, and usually on the platforms

as well. Sections of the map are also displayed in the carriages of the underground trains. Before you begin, it helps to know which line you are starting

on and on which line your destination can be found. If they are on different

lines, look at the map to see where the two lines cross, and note the name of

the station where they meet—that is where you have to change trains. If the

two lines do not cross, keep looking until you find a third line that crosses

both of the other two. Then you will need to change trains twice.

You can buy a ticket from one of the automatic machines or from the

ticket office. Either way, you need to know the name of the station you are

going to. You also need to know whether you want a "single" ticket, which

is valid just to get you to your destination or a "return", which gets you there

and back again. Fares are based on a zone system: the more zones you travel

through, the more expensive your fare is. There are six zones, with zone 1

covering central London and zone 6 covering the outskirts of the system, Q13

including, for example, Heathrow Airport. Most of the underground maps

show which stations are in which zones. A single ticket for travel through all

six zones currently costs £4. Depending on how far you are travelling and

how many journeys you need to make, it may be cheaper to buy a one-day Q14

Travel card, which gives you unlimited travel on all London underground

and bus services the day you buy it. A one-day Travel card covering all six

zones currently costs £8. You can also buy an Oyster card. This is the best

option if you are going to be in London for a long time. You get a discount Q15

on all tickets—usually about 10%-and you don't have to queue to buy tickets.

Just buy credit for your card and then use it as directed when you enter

and leave underground stations at the start and finish of your journeys.

At underground stations you must pass through an automatic gate. Put Q16

your ticket into the slot to the right of the gate. When the gate opens, pass

through. As you pass through, your ticket will pop up from another slot on

the top. Pull your ticket out and take it with you; you need it at the end of

your journey. This is the same procedure for Travel cards. With Oyster cards,

you hold your card over the card reader at special automatic gates. If you Q17

have baggage with you, you can go through a special, larger gate where you

can pass through more easily. Show your ticket to an attendant and ask him

or her to let you through this gate.

Most stations have long escalators leading to and from the trains. Try Q18

to stand to the right-hand side, leaving space for people to walk past you on

the left. When changing trains, get off at the station where the line you are on

crosses the line you need. Follow the signs for the line you need, and the direction Q19

you want to go in. When you leave the system, you must pass through an

automatic gate again to leave the station. Put your ticket in the slot as before.
