题型:填空题 阅读理解。Below are some choices to getting around London by public transportationTubesThe London Underground, commonly referred to as the 'Tube', is the oldest and most extensive underground system in the world and pervades(遍及)both the life and layout of London. Twelve underground lines, each with a different name and colour, are supplemented by the privately operated Docklands Light Railway (tel: (020) 7363 9700) connecting the City of London and the Docklands. The entire network is divided into six concentric zones, which determine the price of tickets. In the city centre (zone one) a single ticket costs £1.50, otherwise single fares are £0.90 (one zone) up to £2.20 (four zones). Carnets of ten zone-one tickets cost £11. Tickets must be passed through the barrier ticket gates in order for the passenger to enter and leave the system (and avoid a £10 penalty(损失)fare). The London Underground runs 05:30-24:30 but should be avoided (where possible) during rush hour - 08:00-09:30 and 17:00-18:30 Monday to Friday.Double-decker busesLondon's famous red 'Routemaster' double-decker buses are slowly being replaced by more modern single and double deckers. There are now only two fare zones. Any journey that includes the city centre zone is £1 and any journey outside this zone is 70p. Tickets are bought from the driver or bus conductor upon boarding and there is a £5 fine for travelling without a valid ticket. Carnets of six tickets (for any zone) can be purchased for £3.90. FerriesThere are a number of services operating on the Thames. Commuter ferries between the Savoy Pier (Embankment) and Greenland Pier (Greenwich) are run by Collins River Enterprises (tel: (020) 7977 6892; website: www.thamescat.com. Fares cost between £1.50 and £2.70 for a single and £2.50 and £4.70 return. Riverside Launches (tel: 020 7352 5888) operate a commuter service between Chelsea/Cadogan and Embankment for £4 (single) or £8 (return). These commuter services operate between Monday and Friday 06:35-19:44.
