Generations of Americans have been brought up to believe that a good breakfast is essential to one's life. Eating breakfast at the start of the day, we have 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 as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained, the number of people who didn’t have breakfast increased by 33%—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America.

For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting breakfast. “Going without breakfast does not affect work,” said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, “nor does giving people breakfast improve work.”

Scientific evidence linking breakfast to better health or better work is surprisingly inadequate, and most of the recent work involves children, not grown-ups. “The literature,” says one researcher,  Dr Earnest Polite at the University of Texas, “is poor.”

As my train wouldn’t leave for another hour, I had plenty of time to spare. After buying some newspapers to read on the journey, I made my way to the   36  office to collect the heavy suit-case I had left there days before. There were only a few people waiting, and I  37   my wallet to find the receipt (收据)  38   my case. The receipt didn’t seem to be  39   I had left it. I emptied the  40   of the wallet, and railway-tickets, money, and photographs fell out of it;  41   no matter how hard I searched, the receipt was nowhere to be found.

When my  42   came, I explained the situation sorrowfully to the assistant. The man looked at me suspiciously(猜疑地)  43   to say that he had heard this type of story many times and asked me to  44   the case. I told him that it was an old, brown-looking object not  45  from the many cases I could see on the shelves. The assistant then gave me a form and told me to make a  46  of the chief contents of the case. If they were  47 , I could take the case 48 . I tried to 49  all the articles I hurriedly packed and wrote them down as they came to me.

After I had done this, I went to look among the shelves. There were hundreds of cases there and for one fearful moment, it  50  to me that if someone had picked the receipt up, he could have easily claimed(领取) the case lying on its side high up in a corner. After  51  the articles inside, the assistant was soon  52  that it was mine and told me I could take the case away  53  I took out my wallet: this time to  54 . I pulled out a ten-shilling note and the “ 55” receipt slipped out with it. I felt embarrassed and looked up at the assistant. He was nodding his head knowingly, as if he wanted to say that he had often seen this happen before too!
