     Visitors to Britain are always complaining about English food. But they do not really know what they

are talking about because they rarely get a chance to eat it. Most of the restaurants in large towns have

foreign owners and serve foreign food. When visitors are invited to eat in an English home, their hosts

often feel they must offer them something foreign and exotic (奇特的) .

     Those of us who do know English food realize that at its best it can be really very good. On the other

hand it is true to say that it is sometimes terrible. Part of the problem is that we are not really interested in

food-we eat to live, we don't live to eat. So we don't generally spend necessary time and effort needed

to cook really good meals or ready prepared food which only needs heating up before eating.

     You can find the best English food in the country away from large towns, where life is slower and

people are not in such a hurry. But more visitors come to London because they are interested in shopping and sightseeing. They do not come because of food, so why should they complain about it?
