University of Arizona researcher Dr. William Rathji says that after a study based on looking into garbage cans, the average family wastes at least $150 per year in food.
"Homemakers go out of their way to save pennies at the store and then don't realize that waste of edible (可食用的) foods adds up much more at home," said Dr. Rathji. He was one of about 100 food experts who met in Boise for a conference on food waste and ways to prevent it.
American families throw out between 8% and 20% of edible food at a cost of $4.5 billion per year. That's almost as much as the federal government spends every year for food stamps and child nutrition programs.
He found that food items which are costly and in short supply tend to be wasted more. During the 1973 meat shortage, meat waste increased to 9%, compared with 3% in 1974 and 1975. Sugar and sugar products waste jumped to 19% in 1975, when sugar prices doubled from the previous year.
Dr. Rathji theorizes that high prices force consumers to experiment, sometimes buy in large quantities. In the case of meat, sometimes low-priced cuts for unappetizing varieties are purchased, consumers then tend to waste more.
His theory is that the more variety in food bought, the more wasted. Regular bread is wasted at about a 10% rate, but specialty breads and rolls are wasted at a 20% rate.
If people are eating the same thing every day, they learn how to manage it. But if you're trying to pull something out of the cookbook every night, that's bound to be some waste.
Another finding is that lower income families waste less food than middle and upper income families. And the study found that dog food, which accounts for 8% of a shopping cart, is rarely wasted. Fresh produce and frozen items are more likely to be wasted.
The study also showed people with the most knowledge of safe, edible food waste the least. Much food is tossed out because a homemaker suspects it is spoiled when it is not.

Passage Four：Questions 36 to 40 are based on the following passage.The decline in moral standards—which has long concerned social analysts—has at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad.
The fact the ordinary citizens are now starting to think seriously about the nation’s moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.
But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. “The thought that ‘I’m in it for me’ has become deeply rooted in the national consciousness,” Ms. Elshtain says.
Some of this can be attributed to the disintegration of traditional communities, in which neighbors looked out for one another, she says. With today’s greater mobility and with so many couples working, those bonds have been weakened, replaced by a greater emphasis on self.
In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the U.S. and Elshtain says the public is correct to sense that: Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and a high rate of births to unmarried mothers.
The desire for a higher moral standard is not a lament (挽歌) for some nonexistent “golden age,” Elshtain says, nor is it a wishful (一厢情愿的) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor the lessening of prejudice.
Moral decline will not be reversed until people find ways to counter the materialism in society, she says. “Slowly, you recognize that the things that matter are those that cant’ be bought.”
第36题：Professor Elshtain is pleased to see that Americans ________.
A) have adapted to a new set of moral standards
B) are longing for the return of the good old days
C) have realized the importance of material things
D) are awakening to the lowering of their moral standards

In 1950, a young man would have found it much easier than it is today to get and keep a job in the auto industry. And in that year the average autoworker could meet monthly mortgage (抵押贷款) payments on an average home with just 13.4 percent of his take-home pay. Today a similar mortgage would claim more than twice that share of his monthly earnings.
Other members of the autoworker’s family, however, might be less inclined to trade the present for the past. His retired parents would certainly have had less economic security back then. Throughout much of the 1960s, more than a quarter of men and women age 65 and older lived below the poverty level, compared to less than 10 percent in 2010.
In most states, his wife could not have taken out a loan or a credit card in her own name. In 42 states, a homemaker had no legal claim on the earnings of her husband. And nowhere did a wife have legal protection against family violence.
Most black workers would not want to return to a time when, on average, they earned 40 percent less than their white counterparts (职位相对的人), while racially restrictive agreements largely prevented them from buying into the suburban neighborhoods being built for white working-class families.
Today, new problems have emerged in the process of resolving old ones, but the solution is not to go back to the past. Some people may long for an era when divorce was still hard to come by. The spread of no-fault divorce has reduced the bargaining power of whichever spouse is more interested in continuing the relationship. And the breakup of such marriages has caused pain for many families.
The growing diversity of family life comes with new possibilities as well as new challenges. According to a recent poll, more than 80 percent of Americans believe that their current family is as close as the one in which they grew up, or closer. Finding ways to improve the lives of the remaining 20 percent seems more realistic than trying to restore an imaginary golden age.
61. What do we learn about American autoworkers in 1950？
A) They had less job security than they do today.
B) It was not too difficult for them to buy a house.
C) Their earnings were worth twice as much as today.
D) They were better off than workers in other industries.
62. What does the author say about retired people today？
A) They invariably long to return to the golden past.
B) They do not depend so much on social welfare.
C) They feel more secure economically than in the past.
D) They are usually unwilling to live with their children.
63. Why couldn’t black workers buy a house in a white suburban neighborhood？
A) They lacked the means of transportation.
B) They were subjected to racial inequality.
C) They were afraid to break the law.
D) They were too poor to afford it.
64. What is the result of no-fault divorce？
A) Divorce is easier to obtain.
B) Domestic violence is lessened.
C) It causes little pain to either side.
D) It contributes to social unrest.
65. What does the author suggest society do？
A) Get prepared to face any new challenges.
B) Try to better the current social security net.
C) Narrow the gap between blacks and whites.
D) Improve the lives of families with problems.
