An environmental group called the Food Commission is unhappy and disappointed because of the sale of bottled water from Japan. The water, it angrily argues an public, has traveled 10,000 "food miles" before it reaches Western customers. "Transporting water halfway across the world is surely the extremely stupid use of fuel when there is plenty of water in the UK." It is also worried that we are wasting our fuel by buying prawns(对虾) from Indonesia (7,000 food miles) and carrots from South Africa (5,900 food miles).

Counting the number of miles traveled by a product is a strange way of trying to tell the true situation of the environmental damage done by an industry. Most food is transported around the world on container ships that are extremely energy-efficient (高能效的). It should be noted that a ton of butter transported 25 miles in a truck to a farmers' market does not necessarily use less fuel on its journey than a similar product transported hundreds of miles by sea. Besides, the idea of "food miles" ignores the amount of fuel used in the production. It is possible to cut down your food miles by buying tomatoes grown in Britain rather than those grown in Ghana; the difference is that the British ones will have been raised in heated greenhouses and the Ghanaian ones in the open sun.

What the idea of "food miles” does provide, however, is the chance to cut out Third World countries from First World food markets. The number of miles traveled by our food should, as I see it, be regarded as a sign of the success of the global (全球的) trade system, not a sign of damage to the environment.

How many people have I met who have told me about the book they have been planning to write but have never yet found the time too many.

This is Life, all right, but we do treat it like a rehearsal (排演) and, unhappily, we do miss so many of its best moments.

We take jobs to stay alive and provide homes for our families always making ourselves believe that this style of life is merely a temporary state of affairs along the road to what we really want to do. Then, at 60 or 65, we are suddenly presented with a clock and several grandchildren and we look back and realize that all those years waiting for Real Life to come along were in fact real life.

In America they have a saying much laughed at by the English：“Have a nice day” they speak slowly and seriously in their shops, hotels and sandwich bars. I think it is a wonderful phrase, reminding us, in effect, to enjoy the moment: to value this very day.

How often do we say to ourselves, "I'll take up horse-riding (or golf, or sailing) as soon as I get a higher position," only to do none of those things when I do get the higher position.

When I first became a reporter I knew a man who gave up a very well paid respectable job at the Daily Telegraph to go and edit a small weekly newspaper. At the time I was astonished by what appeared to me to be his completely abnormal (反常的) mental state. How could anyone turn his back on Fleet Street in central London for a small local area?I wanted to know.

Now I am a little older and possibly wiser, I see the sense in it. In Fleet Street the man was under continual pressure. He lived in an unattractive London suburb and he spent much of his life sitting on Southern Region trains.

A. we always try to find some time to write a book
