Informality has reduced parents’ influence on children’s behavior. D. Informality has resulted in the great loss in British economy. C American researchers say drinking tea may help strengthen the body’s defense system against infection．Doctors at Brigham and Women’s Hospital in Boston.Massachusetts.did the study．The team studied a chemical found in black.green.oolong and pekoe tea. This chemical is an amino acidcalled L-theanine．The scientists say it may increase the strength of Gamma delta T cells.which are part of the body’s defenses． First.the researchers mixed some of these cells with antigensfound in the amino acid Antigens help the body react to infection．Then the scientists added some bacteria．Within twenty-four hours.the cells produced a lot of interferon.a substance that fights infection. Cells not mixed with the antigens did not produce interferon． In the second part of the study.eleven people drank five to six cups of black tea every day．Ten other people drank the same amount of instant coffee．That is dried coffee mixed with hot water．Two weeks later.and again two weeks after that.the researchers tested the blood of all twenty-one people．They also looked at what happened when they added bacteria to the blood cells．They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon． Doctor Jack Bukowski led the study. He says the antigens added to the Gamma delta T cells were responsible for the increased reaction to the bacteria．He says the study also showed that the cells were able to remember the bacteria and fight them again the next time． Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated with more people．If the findings prove to be true.he says.then tea drinking might also help protect against bacterial infections．He says the amino acid L-theanine could be removed from tea and used as a drug to strengthen the body’s defenses． 【查看更多】

    　　When families gather for Christmas dinner, some will stick to formal traditions dating back to Grandma’s generation．Their tables will be set with the good dishes and silver, and the dress code will be Sunday-best．

    　　But in many other homes, this china-and-silver custom has given way to a stoneware(粗陶)-and-stainless informality, with dresses appearing an equally casual-Friday look．For hosts and guests, the change means greater simplicity and comfort．For makers of fine china in Britain, it means economic hard times．

    　　Last week Royal Doulton, the largest employer in Stoke-on-Trent, announced that it is cutting down 1,000 jobs－one-fifth of its total workforce．That brings to more than 4,000 the number of positions lost in 18 months in the pottery region．Wedgwood and other pottery factories made cuts earlier．

    　　Although a strong pound and weak markets in Asia play a role in the downsizing, the layoffs in Stoke have their roots in earthshaking social shifts．A spokesman for Royal Doulton admitted that the company“has been somewhat slow in catching up with the trend”toward casual dining．Families eat together less often, he explained, and more people eat alone, either because they are single or they eat in front of television．

    　　Even dinner parties, if they happen at all, have gone casual．In a time of long work hours and demanding family schedules, busy hosts insist, rightly, that it’s better to share a takeout pizza on paper plates in the family room than to wait for the perfect moment or a“real”dinner party．Too often, the perfect moment never comes．Iron a fine-patterned tablecloth?Forget it．Polish the silver?Who has time?

    　　Yet the loss of formality has its down side．The fine points of table manners that children might once have learned at the table by observation or instruction from parents and grandparents(“Chew with your mouth closed”．“Keep your elbows off the table．”)must be picked up elsewhere．
