From Buckingham Palace to Oxford, the UK is loaded with wonderful icons(标志) of past eras. But it has also modernized with confidence. It’s now better known for vibrant(充满活力的) cities with great nightlife and attraction. Fashions, fine dining, clubbing, shopping — the UK is among the world’s best. Most people have strong preconceptions about the British. But if you’re one of these people, you’d be wise to abandon those ideas. Visit a nightclub in one of the big cities, a football match, or a good local pub and you might more readily describe the English people as humorous and hospitable. It’s certainly true that no other country in the world has more bird-watchers, sports supporters, pet owners and gardeners than the UK. Getting around England is pretty easy. Budget airlines like Easyjet and Rynnair fly domestically. Trains can deliver you very efficiently from one major city to another. Long distance express buses are called coaches. Where coaches and buses run on the same route, coaches are more expensive (though quicker) than buses. London’s famous black cabs are excellent but expensive. Minicabs are cheaper competitors, with freelance (个体的) drivers. But usually you need to give a call first. London’s underground is called the Tube. It’s very convenient and can get you to almost any part of the city. The UK is not famous for its food. But you still need to know some of the traditional English foods. The most famous must be fish and chips. The fish and chips are deep fried in flour. English breakfast is something you need to try. It is fried bacon, with toast and a pot of tea. Other things like shepherd’s pie and Yorkshire pudding are also well-known as a part of English food culture. Pubbing and Clubbing are the main forms of English nightlife, especially for the young. Pubbing means going to a pub with friends, having drinks, and chatting. Clubbing is different from pubbing and includes going to a place of music, or a bar, or any other place to gather with friends. Clubbing can be found everywhere. Usually there is some kind of dress code for clubbing, such as no jeans, no sportswear, while pubbing is much more casual. 1.If you are involved in the real life of local residents, you may find them ______________________________. 2.How many kinds of transportation forms are mentioned in the third paragraph?
