Today I read something about World Wild Fund(WWF)．Its goal is to protect the environment and animals and build a future in which humans live in harmony with nature．Here are some actions WWF will take：
*Protect the world's biological(生物多样化)；
*Make sure that natural resources(资源)can be used again and again;
*Protect wild animals around the world．
And here are some natural facts that WWF has found out：
*As much as 20 percent of the world's species could be gone in the next 30 years;
* 1998 was the warmest year in history．In the past 120 years, there were 10 warmest years and they all occurred after 1981;
*In the last 50 years, more than 75,000 chemicals(化学物质)have been developed and introduced into the environment．
This organization is trying to solve these problems．It is also part of the United Nations．With such wonderful organizations like WWF, don't you think we can make the world a better place to live in?

join the United Nations

4．
D．
5．
(3)
Why could the world's species be gone in the next 30 years?
[ ]
A．
Because people kill them．
B．
Because of the warm weather．
C．
Because of the bad environment around us．
D．
Because there are too many species in the world．

In the past 50 years, more than 75,000 chemicals have been developed and introduced into the environment, so the environment is becoming ________．
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．
(1)
What does the story of Jeanne Calment prove to us?
[ ]
A．
People can live to 122．
B．
Old people are creative．
C．
Women are sporty at 85．
D．
Women live longer than men．
(2)
According to Steve Austad at the University of Texas, ________
[ ]
A．
the average human life span could be 110
B．
scientists cannot find ways to slow aging
C．
few people can expect to live to over 150
D．
experts aren’t sure how long one can live
(3)
Who thinks that a scientist will become famous if he makes longevity?
[ ]
A．
Jerry Shay．
B．
Steve Austad．
C．
Rich Miller．
D．
George Martin．
(4)
What can we infer from the last three paragraphs?
[ ]
A．
Most of us could be good at sports even at 120．
B．
The average human life span cannot be doubled．
C．
Scientists believe mice are aging at a slower speed than before．
D．
New techniques could be used to change flies into a new species．
