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. "
"... nor does giving people breakfast improve performance" (Lines 4~5, Para. 3) means_____.
选项 A、anyone without breakfast does not improve performance
B、not giving people breakfast improves their performance
C、having breakfast does not improve performance, either
D、people having breakfast do improve their performance, too
答案C
解析 本题是一道句子含义类问题。问文章第三段最后一句话中的nor does giving people breakfast improve performance是什么意思。根据文章上下文，近年来的一些研究表明，特别对于成年人来说，不吃早饭并没有什么不好。“不吃早饭并不影响工作效果”，伦敦伊丽莎白女王学院的前营养学教授阿诺德·E·本德尔说，“让人们吃早饭也不会提高工作效果”。因此，本题的正确答案应是C“吃了早饭也不会提高工作效果”。
