Brighton: It is a seaside resort on the English Channel. Only 50 miles from London, it offers a good variety of lively entertainment. It is a cheerful place, busy and crowded in the summer, but alive in every season of the year. Its royal pavilion(布莱顿皇宫)is a masterpiece of English architecture.

Durham: Whatever travelers see or don't see in England, they must see this city, in the northeast, just south of Newcastle­upon­Tyne. No one will forget the sight of its cathedral(教堂)and castle rising together on a steep hill overlooking a loop in the River Wear, which almost surrounds them. The cathedral itself is one of the great medieval(中世纪的，公元476～1500)buildings in Europe.

Liverpool: A port in the northwest of England which possesses a quality that is not found in quite the same way anywhere else in England: the quality of grandeur (壮观). Liverpool has this grandeur in its site on the broad River Mersey (more than half a mile wide) with the houses rising near it; in its great dock buildings, its broad streets, and its two enormous cathedrals.

Edinburgh: It has long been the capital of Scotland. Edinburgh Castle is Edinburgh's important building, controlling the city from its perch on a rock over a hundred meters above sea level. Another important building is the Palace of Holyrood House, begun by James Ⅲ around 1500. Between the castle and the palace is the Royal Mile, which was the center of Edinburgh life before the 17th century and is fascinating to visit now.
