It's certainly the biggest city in Europe(欧洲).New York is as big as London, if not bigger. The streets in London are crowded and there is one of the world's biggest underground railway systems(地铁系统). The streets in New York are just as crowded as in London. And the New York subway carries more people each day than the London underground. There are a lot of big stores in these two cities. But New York has more supermarkets than London.
