Would you know what to do during a big earthquake(地震)?Scientists have some advice for us.
If the ground begins shaking while you are driving, stop your car on the roadside and stay in it.If you are in a tall building, don't use the lift and never jump out of the windows.When you are in a living room, find a strong table or rush into a smaller room like washroom.Then lie down your body.Take care of your head.When you are in a public place, like supermarket or cinema, don't crowd in jam(拥挤), or you may fall over and get hurt.Cross your arms to protect yourself.You can also find a place to hide.
After the main shake, quickly run out of the dangerous building for there will be small earthquakes.If you are safe, remember not to engagethe phone line, keep it free for rescue(援救)using.Don't go to the hospital if you are not badly hurt, others will really need help.Take part in the rescue action if you can.

Jeanne Calment took up skating at age 85, made her first movie appearance at age114.and held a concert in the neighborhood on her 121 st birthday.
When 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(限制)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 sul33rise 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 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 1 20.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 guessing
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 HS living until about 120.Researchers are working on treatments that make the life span of mice longer by 50 percent at most.
So, if the average(平均)human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120.”
So what can we learn 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'snever 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.”He says with a smile.

Once there was a bookseller.He didn't like paying for anything.One day he hurt one of his feet because a big box of books fell on it.
“You'd better go and see the doctor.”said his wife.
“No,”he said,“I'll wait until the doctor comes into my shop next time.Then I'll ask him about my foot.If I go to see him,I shall have to pay him some money.”
The next day a doctor came into the shop.The bookseller told him about his bad foot.The doctor looked at it.
“Yes.”said the doctor.“You must put that foot in hot water every night.Then you must put something on it.”
He took out a piece of paper and wrote something on it.“Buy this and put it on the foot before you go to bed every night,”he said.
“Thank you.”said the bookseller.“And now, sir,here are your books.”
“How much are they?”asked the doctor.
“Two pounds.”
“Good.”said the doctor,“I shall not have to pay you anything.”
“Why?”asked the bookseller.
“I told you about your foot.I want two pounds for that.If people come to my house,I ask them for one pound for my advice.But when I go to their house.I want them to pay two pounds.And I came here,didn't I? Goodbye.”
