问题     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, food being the 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 latest year for which figures are available, the number of people who didn’t have breakfast increased by 33 percent—from 8. 8 million to 11. 7 million according to the Chicago-based Market Research Corporation of America.
    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 College in London, "nor does giving people breakfast improve performance. "
    Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. "The literature," says one researcher, Dr. Ernesto Pollitt at the University of Texas, "is poor. "
The word "literature" in the last sentence refers to______.
选项 A、stories, poems, plays, etc.
B、written theory on a particular subject
C、any printed material
D、the modern literature of America
答案B
解析 本题是一道词汇含义类问题。问本文中最后一句话中的词literature是什么意思。根据文章上下文，将早饭与改善健康及工作表现联系起来的科学依据并不十分充分，并且，大部分的研究涉及的是儿童，而不是成年人。对此，得克萨斯大学的一位科学家厄尼斯图·玻利特博士说：“这些理论是很不完善的。”因此，本题的正确答案应是B“关于某种问题的书面理论”。
