     Going on holidays is best choice for the Europeans to relax themselves, especially in the UK.

However, much has changed during the past decades(几十年).

     One of the most traditional British holidays was the"seasideholiday". Families got on a train or

into a car and traveled to seaside towns nearby to sunbathe on the beach, buy ice-creams and

eatfish and ships and so on.

     In the late 1970s, more and more British people started traveling to other countries in Europe

for their summer holidays(July-August) because the weather wasn't very good, even in summer.

The"package holiday"was particularly popular with most families.

     In the 1980s and 1990s, young people in the UK became wealthier, so many of them traveled

to countries all over the worldfor their holidays.

     These years, especially after the world financial crisis(金融危机), most British people can not

afford to spend their holidays abroad. They again begin to choose to stay in their own home and

go on a few day trips rather than spending money on hotels. Theycall this sort of vacation a"staycation".
