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.

Although hurricane season doesn't begin until June 1, a Pacific storm has already struck. El Salvador, which was ruined by a Caribbean storm in 1995, was hit by Hurricane Adrian on Friday. This is the first Pacific-born hurricane to ever reach land in this Central American country.

Some 14,000 people left from the western coast of El Salvador. The storm weakened as it crossed land, heading east. Heavy rains created deadly flooding problems in the hurricane's wake.

Adrian is the first Pacific storm of the season. It reported maximum continuous winds of 75 miles per hour, the minimum strength of a hurricane. A Category 3 hurricane, Adrian also caused damage and flooding in Honduras. It is expected to break up before reaching the Caribbean Sea on the eastern coast of Central America.

　 Hurricane season typically begins June 1 and lasts through November 30．The National Oceanic and Atmospheric Administration (NOAA) has predicted (预告) seven to nine hurricanes for the 2005 season.

"It is difficult to make any kind of an exact prediction of how many of these will strike land," NOAA administrator Conrad Lautenbacher said. He predicts two to three hurricanes will strike the U.S. this season.

Last year, six of nine hurricanes reached Category 3 strength or higher. Four of those hit Florida within a six-week period. Altogether, Hurricanes Charley, Frances, Ivan, and Jeanne caused more than $40 billion in damage in the Sunshine State.

This year's forecast is based on ocean temperatures. Warmer temperatures produce more tropical storms, which can then turn into hurricanes.

"The issue, really, this year is the unusually warm sea surface temperatures in the Atlantic," said Frank Lepore of the National Hurricane Center.

1．Which of the following is the 2005 first hurricane?

　 A．Charley. 　 B．Adrian. 　　 C．Jeanne. 　　 D．Frances.

2．How many countries struck by the hurricane are mentioned in the text?

　 A．Six. 　　　 B．Nine. 　　　 C．Five. 　　　 D．Three.

3．We can infer that warmer ocean temperatures ______.

　 A．have nothing to do with the hurricane

　 B．cause less hurricane

　 C．are more likely to cause the hurricanes

　 D．do a lot of damage to the areas along the coast

4．The passage implies that _______.

　 A．hurricane season comes early this year

　 B．every hurricane formed in oceans could cause great damage to the land

　 C．hurricane often comes in winter and spring

　 D．tropical storm is more severe than hurricane
