听力原文： Generations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.
But for many people the thought of food first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the number of people who didn't have breakfast increased foam 8.8 million to 11.7 million. For those who feel pain of guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. "Going without breakfast does not affect performance," said Arnold E. Bender, former professor of nutrition at Queen Elizabeth Collage in London, "nor does giving people breakfast improve performance."
Scientific evidence linking breakfast to better health or better performance is surprisingly indicated, and most of the recent wonk involves children, not adults.
