ДАЮ 100 БАЛЛОВ In your own words , answer the questions based on the information given in the text .
1 Name a problem you could face with an illegitimate taxi driver .
2 What might a European pedestrian be fined for in New York ?
3 What should a visitor avoid in the New York underground system ?

A New York is one of the most exciting city break destinations in the world New York is no more dangerous than any other city of its size . but Manhattan can be such a daunting place for visitors . It is essential for visitors to learn a few basics for staying safe . There's a good chance you'll take a traditional yellow cab in New York , but don't assume every cab you see is authorised . Ensure your driver has the official NYC Taxi logo on display in the vehicle . Unregistered drivers are usually uninsured and looking to overcharge their customers . It is common courtesy to tip the driver , unless you were given a very good reason not to . Failing to tip with typically outspoken New York cabbie , however would be to risk getting involved in an angry scene . When you arrive in the city , resist the urge to go sightseeing immediately . It's not only sensible to drop off your luggage , but also to lock away your valuables . Most New York hotels have safes in their rooms and it's wise to use them . Many people seem to be able to freely walk in and out of hotels in New York . For the same reason , it's advisable to check who's at your room door if you hear a knock . Most doors will have a peephole you can look through but you can always call reception if you're in doubt DWhen you're in the streets , bear in mind that New York has its fair share of pickpockets Avoid falling victim to them by trying not to look like a tourist . Also , give the impression that you know exactly where you're going . If you need look at your map . New York has endless cafés where the stressed - out tourist can stop . Sit down and get your bearings or just watch the hustle and bustle around you . do Even if blend in with residents , you should still be on your guard Europeans usually don't realise that stepping into the road when there's no walk signal or green man , known as jaywalking . is actually a criminal offence in New York . Don't risk a fine or , worse being run over by a car . If you're in a hurry , use the underground system . The New York ' subway is an inexpensive and reliable way to get around although some common - sense precautions should be followed . Don't , for example , board an empty carriage . In fact , it's a good idea to stay close other people as much as possible . This isn't always possible after 11pm , so solo travellers should either travel earlier or find an alternative late at night .
