A. Some visitors say that London is a very expensive city, but there are a few things to do
which do not cost a lot of money. Most museums are free and give guided tours as well as
lectures. The National Theatre next to the Royal Festival Hall also has free concerts in the foyer
every evening and on Saturday lunchtimes. Some cinemas are cheaper on Mondays; others sell
half-price tickets before 6 pm.
B. Florida was bought from the Spanish in 1819. It is the southernmost state on the mainland
and has a long coastline on the Atlantic Ocean. Oranges grow all year round even in winter,
when the weather is very cold further north. The warm climate has made Florida an important
vacation resort. More than ten million visitors come to Miami Beach every year. There are also
many theme parks and other entertainment.
C. Spain is famous for its unusual lifestyle. For example, Spanish people usually have lunch
at 2.30 pm and dinner at 10.00 pm. People don’t usually go to bed before midnight. At 10.00 on
Friday and Saturday nights the bars and restaurants are full. Spanish night-life really starts at mid
night. A lot of disco-bars don’t close before 6.00 in the morning. On the east coast of Spain some
discos open at 10.00 on Sunday mornings!
D. The Welsh have been famous for their singing for centuries. If you go to any Welsh rugby
match, you will hear supporters singing in harmony. Male-voices choirs are found throughout
Wales and many Welsh people have become famous opera singers. The reputation of Wales as a
centre for music attracts musicians from all over the world to its various festivals.
E. Budapest has a population of over two million people. The River Danube divides the city
into two parts. On the west bank there are the woods and hills of Buda and the old town. On the
east ban k there is the bigger and more modem Pest, the business and shopping centre. From
Buda there are wonderful views of Pest and the river. Six bridges join Buda and Pest. For nearly
a thousand years Buda and Pest w ere two towns. Then in 1873 they joined and became one city,
Budapest.
