When you cough or sneeze, you’d better turn your head away from others and cover your mouth with the full part of your hand．And then, you should say, “Excuse me．”
This seems so simple, but it is surprising how many kids have never been told to do this．Actually, I notice adults all the time who cough and sneeze in public without placing a hand over the mouth．One important thing I point out to the kids is that after they sneeze or cough on their hands, they should wash their hands as soon as possible．If not, they will be passing those germs(细菌)along to everything and everyone they touch．
If you come to a door and someone is following you, hold the door．If the door opens by pulling, pull it open, stand to the side, and allow the other person to pass through first, then you can walk through．If the door opens by pushing, hold the door after you pass through．
After a few weeks of seeing kids try to get through doors in the school and watching them enter restaurants as the door hit other people, I knew I had to discuss the problem with my students．Teaching them small acts of kindness, such as letting someone else go through a door first as they hold it open, may seem unimportant, but it can go along way toward helping students realize hot to be polite and thank others．Once they’ve been told, they’re halfway there．
When we have to go up moving stairs, we will stand to the right．That will give others who are in a hurry a choice of walking up the left-hand side of the moving stairs．When we are going to enter a lift, the underground, or a doorway, we will wait for others to exit before we enter．
After college when I moved to London, I was surprised at how polite everyone was in the subways．I was even more touched when I traveled to Japan．In both places, people made efforts to make way for others．On moving stairs, everyone stood to the right and walked to the left．On lifts, everyone would stand over to the side and allow others to exit before they would begin to enter．

From the passage we ca know the writer is a _________．
She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday．
Whe n it comes to long life, Jeanne Calment is the world’s recordholder．She lived to the ripe old age of 122．So is 122 the upper limit to the human life span(寿命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond?
Researchers don’t entirely agree on the answers．“Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas．
Steve Austad at the University of Texas agrees．“People can live much longer than we think,”he says．“Experts used to say that humans couldn’t live past 110．When Calment blew past that age, they raised the number to 120．So why can’t we go higher?”
The trouble with guessing how old people can live to be is that it’s all just guessing．“Anyone can make up a number,”says Rich Miller at the University of Michigan．“Usually the scientist who picks the highest number gets his name in Time magazine．”
Won’t new anti-aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of us kicking until about 120．Researchers are working on treatments that lengthen the life span of mice by 50 percent at most．So, if the average human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120．”
So what can we conclude from this little disagreement among the researchers?That life span is flexible(有弹性的)，but there is a limit, says George Martin of the University of Washington．“We can get flies to live 50 percent longer,”he says．“But a fly’s never going to live 150 years．”
“Of course, if you became a new species(物种)，one that ages at a slower speed, that would be a different story,”he adds．
Does Martin really believe that humans could evolve(进化)their way to longer life?“It’s pretty cool to think about it,”he says with a smile．
