6 阅读理解。 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.

A. they don"t often eat English food B. they know little about English food C. they only eat English food in English home 2. When English people have guests they prefer to ____ .
