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.
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 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, ”he says with a smile.

“Imagine you are walking along the road. Suddenly you fall over and all the passers-by burst into laughter. You feel very 1 and think the world is laughing at you . But in fact, five minutes later, they have 2 it ever happened.” The other day when I came across these words in an article, I didn’t agree with the 3 .
The author thinks the best thing to do in this kind of 4 is to pretend nothing has happened, and so avoid 5 trouble.
I admit that we should keep 6 because “Your tears will only remind others of what happened, while your 7 can let them forget it.” But this is far from satisfactory. We should do 8 to make things better.
I used to be a(n) 9 girl and not very good at maths. Our new maths teacher asked me a question and I still remember how I hung my head in 10 when I couldn’t answer it.
“If you don’t know the answer, just tell me.” the teacher said, “If you don’t how can I know 11 you know the answer or not?” All of my classmates burst into laughter. My face turned red but the teacher 12 me to go to the blackboard and 13 what I knew. If I had 14 the words in the article, I would have given up. But I tried my best. And to everyone’s 15 , I succeeded! The teacher smiled and said, “Well done! I 16 you could do it!”
Since then, I have become active in maths as 17 as in other subjects. I used to think doing maths exercises was a waste of time. But now, I know 18 I do can make things better. Everyone is the 19 of his own fate.
If we make mistakes, we should take on an active 20 . Laugh, and the world laughs with you; weep(哭泣), and you weep alone.

A special laboratory at the University of Chicago is busy only at night. It is a dream laboratory where researchers are at work studying dreamers. Their findings have discovered that everyone dreams from three to seven times a night, although in ordinary life a person may remember none or only one of his dreams.
While the subjects—usually students—sleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of a dream. Surprisingly, all subjects sleep soundly.
Observers report that a person usually fidgets(烦躁不安) before a dream. Once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show. As soon as the machine shows that the dream is over, a buzzer wakens the sleeper. He sits up, records his dream, and goes back to sleep—perhaps to dream some more.
Researchers have found that if the dreamer is wakened immediately after his dream, he can usually recall the entire dream. If he is allowed to sleep even five more minutes, his memory of the dream will have disappeared.

Poetry is an interesting form of writing. It is very free, has few restrictions and can be a great way to express feelings. Writing a poem is all about observing the world within you or around you.
To write a poem, first you should begin with an idea or inspiration. Inspiration may come at any time unexpectedly. It may be a specific person, place or thing that causes some sort of strong emotion. It may be more of an abstract idea or release of emotion.
After getting the idea, you can write down everything that comes to mind. Don’t think much and let all feelings pour out. Remember everything can be thrown out later.
Then, you can think about its form and begin to organize thoughts. Poetry comes in many forms, from epic poetry that has a story to dramatic poetry intended to be performed. Try them all out. One will come naturally. Maybe different poems fit different forms. When you write a poem, think about both meter (韵律) and rhythm carefully, which are equally important in poetry. Meter is the fixed pattern of the poem, while rhythm refers to the sound when it is spoken. It is also important to use a lot of descriptive words. Create imagery (意象) with words, trying to make them attractive to all the senses. For auditory (听觉的) interest, try repeating of similar sounds in a sentence or phrase. All of this adds life and interest to a poem.
After you finish your work, don’t be afraid to share your work with others. When others point out your weakness, accept and grow from it.
