    　　Mouth bacteria grow fast in airless conditions．Oxygen rich saliva(唾液)keeps their numbers down．When we sleep, for example, the saliva stream slows, and sulfur(硫)producing bacteria gains the upper hand, producing classic “morning breath”．

    　　Alcohol drinking, too much talking, breathing through the mouth during exercise, anything that dries the mouth produces bad breath．So can stress, though it's not understood why．Some people's breath turns sour every time they go on a job interview．

    　　Saliva flow gradually slows with age, which explains why the elderly have more bad breath trouble than younger people do．Babies, however, who make plenty of saliva and whose mouths contain relatively few bacteria have characteristically sweet breath．

    　　For most of us, the simple, dry mouth variety of bad breath is easily cured．Eating or drinking starts saliva and sweeps away many of the bacteria．Breakfast often stops morning breath．

    　　Those with constant dry mouth find that it helps to keep gum, hard candy, or a bottle of water or juice around．Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria．

    Surprisingly, one thing that rarely works is mouthwash．The liquid can mask bad breath smell with its own smell, but the effect lasts no more than an hour．Some mouthwashes claim to kill the bacteria responsible for bad breath．The trouble is, they don't necessarily reach all offending germs．Most bacteria are well protected from mouthwash under thick layers of mucus(粘液)．If the mouthwash contains alcohol－as most do－it can worsen the problem by drying out the mouth．

    　　“Steve, you did your best．Come on．Let’s go and get your medal,” Coach said．He looked at me right in the eyes．“You gave it your all．You deserved that trophy(战利品)，not the silver medal．You deserve it, but he is getting it．You really won and the whole team is proud．”

    　　I walked up to get my medal, my head held high．I shook the hands of the judges and my opponent, took m medal and saw that, in the eyes of everyone, I had really won．No matter what trophy or medal my opponent took home, no matter what．He may have had my trophy, but he could never have my will．

    　　It was at least two months before Christmas when nine-year-old Almie Rose told her father and me that she wanted a new bicycle．As Christmas drew near, her desire for a bicycle seemed to fade, or so we thought．We bought the latest rages．Baby-Sitter’s Club dolls, and a doll house．Then, much to our surprise, on December 23rd, she said that she “really wanted a bike more than anything else．”

    　　It was just too late, what will all the details of preparing Christmas dinner and buying last-minute gifts, to take the time to select the “right bike” for our little girl．So here we were－Christmas Eve around 9∶00 p. m., with Almie and her six-year-old brother, Dylan, nested snug in their beds．Now we could only think of the bicycle and the disappointment of our child．“What if the bicycle out of clay(a kind of earth)and write a note that she could trade the clay model in for a real bike?” her dad asked．“This is an expensive item and she is ‘such a big girl,’ and it would be much better for her to pick it out．”So he spent the next four hours painstakingly working with clay to make a tiny bike．

    　　On Christmas morning, we were excited for Almie to open the little heart-shaped package with the beautiful red and white clay bike and the note．Finally, she opened it and read the note aloud．“Does this mean that I trade in this bike that Daddy made me for a real one?”Beaming, I said,“Yes．”Almie had tears in her eyes when she replied,“I could never trade in this beautiful bicycle that Daddy made me．I’d rather keep this than get a real bike．”At that moment, we would have moved heaven and earth to buy every bicycle on the planet!
