us a lot. For me it was Pink Floyd* and the Rolling Stones.* I also know that
British films and actors often rank among the
best at international film festivals." (Barbara, Poland) "If I wanted
to go to study abroad, England would be the only place. In England you can get
qualifications that are recognized
throughout the world." (Syed, Pakistan) "Actually, I like British food,
though it doesn't rank highly. I also
think that its electrical goods are of high quality.
(Sarah, US) "I know that Britain is a rich country with a strong economy. But I think it should
care more about old people and do more for poor people and poor countries."
(Yang, China). "I've been to London and admired its beautiful landmarks.
Britain has an international reputation
for its historical sights. However, I wish London were not so expensive and
Londoners should be friendlier to foreigners." (Paula, Mexico)

many countries, though it is an island state. It is a member a of many

has had an enormous influence on the
world. Some of the greatest inventors have been British and many everyday
things were invented by the British."
