I always enjoy summer. Do you? In summer, I like to relax and forget about school. I don't
have to get up early and I can see my friends any time I want.
I like to spend my holidays with my parents. We usually go somewhere with our parents. We
love to swim, lie in the sun, but most of all I prefer going camping. We go to different places in
Britain and sometimes abroad. In Britain, I like going to Devon, Somerset and Scotland – but my
favourite place of all is Yorkshire. It has a lovely countryside and fantastic old buildings. The only
problem is the weather!
Last summer, I had two holidays. One was in Somerset, in a little village by the sea, and
another was in Naples, in Italy. I went with my mother to Italy – by train! Our trip was unforgettable!
Sam, 12 Britain
