     People travel for a lot of reasons. Some travelers go to see places of a long history. Others are

looking for cultures, or just want to have their pictures taken in front of famous places. Most European

travelers are looking for a sunny beach to lie on. Northern Europeans like to pay a lot of money for the

sun because they have so little of it. People of cities like London, Copenhagen and Amsterdam spend

much of their winter in the dark because the days are so short, and much of the rest of the year in the

rain. This is the reason why the sea attracts them. Every summer many people travel to Mediterranean

resorts(度假胜地) and beaches for their vacation. They all come for the same reason: the sun.

     The large crowds mean lots of money for the countries along the sea. Italy's hotels are all booked

without a break every summer, and also French beaches, Spain's coastline.

     The Mediterranean is becoming one of the most polluted seas on earth. But people do not mind much. They don't go there for clean water and they allow traffic jams and seem to like crowded beaches. No

matter how dirty the water is, the coastline still looks beautiful. If the sun shines, it is much better than

sitting in the cold rain in those big cities.
