M：Lisa, do you think we make too much use of tinned and frozen food in Britain?The supermarkets here are full of them，aren’t they? (19)Perhaps that is why our food is not very tasty．as you may have found out already．
W：But frozen foods are convenient and handy．aren’t they? Just think of all tile tedious work we would have to do in the kitchen if it weren’t for frozen foods and the like．
M：Yes．that’s true! (20)But you spend much more time cooking and preparing meals in your country than we do in Britain．don’t you?
W：Yes．I suppose we do．You make less fuss about food than we do．In my own country，we have two big meals a day，that is，lunch and dinner，and we spend a lot of time preparing them．(21)Here in Britain，you have only one big meal a day, apart from breakfast and lunch snack, and you spend much less time preparing it．
M：Yes，but we’re just as fond of good and delicious food as you are．
W：Well, you certainly don’t show it!
M：We do fuss about our meals sometimes，and remenber，we like to eat out on special occasions，such as weekend evenings．birthday parties and other celebrations．London is full of foreign restaurants where you can get all the exotic dishes of the world．You must come out with us one evening，Lisa．
W：Thank you very much，I’d love to．That’s what I like about London．(22)There’s always so much to see and do!I think I made a wise decision when I chose to live and study in London．
