13.Passage Two　　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 despite 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 88 million to 117 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 adults 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(不充分) ,and most of the recent work involves children, not adults. "The literature," says one researcher, Dr. Earnest Polite at the University of Texas, "is poor."Which of the following statements best summarizes the writer's conclusion about the function of breakfast?

Number sense is not the ability to count．It is the ability to recognize a46in number．Human beings are born with this ability．47, Experiments show that many animas are, too．For example, many birds have good number sense．If a nest has four eggs and you remove one, the bird will not48．However, if you remove two, the bird49leaves．This means that the bird knows the50between two and three.

Another interesting experiment showed a bird’s51number sense．A man was trying to take a photo of a crow(乌鸦) that had a nest in a tower, but the crow always left when she saw him coming．The bird did not52until the man left the tower．The man had an53．He took another man with him to the tower．One man left and the other stayed, but they did not54the bird．The crow stayed away until the second man left, too．The experiment was55with three men and then with four men．But the crow did not return to the nest until all the men were56．It was not until five men went into the tower and only four left that they were57able to fool the crow.

How good is a human’s number sense? It’s not very good．For example, babies about fourteen months old almost always notice if something is taken away from a58group．But when the number goes beyond three or four, the children are59fooled.

It seems that number sense is something we have in common with many animals in this world, and that our human60is not much better than a crow’s.50A.distance,B.range,C.difference,D.interval
