If you are travelling from one of London’s international airports to central London, don’t take taxi unless you are very rich! The minimum fare from Heathrow, the airport nearest to central London, is about ￡25. If you are travelling in a group of four people and each of you has a lot of luggage(行李), you may feel that it would be worth paying for a taxi.
If you simply want to cross London from one railway station to another or from a station to your hotel, then a taxi may be a good idea. Although taxis may seem quite expensive, they make life a lot easier if you have a lot of luggage, or if you are not confident about finding your way around the underground system. Here are some useful facts about using taxis：
★Licensed(有许可证的) taxis are large, and usually black, vehicles with a small white plate(牌照) on the back showing a license number and the words Hackney Carriages.
★The best place to find a taxi is at a railway station. Follow the signs for taxi and you will find what is called a taxi rank (a place in the road where a taxi can stop). Another good place to find a taxi is near a large hotel.
★If you are not at a station, you will have to stand in the street and wait for one to go past. Look for a taxi which has an orange light lit up over the driver’s window—this means that it is not being used by anyone else.
★When the taxi is quite close, raise your arm and wave the driver down. The taxi should stop for you.
★When you pay, it is usual to give the driver a tip of at least 10%.
