but Clear Creek County, Colorado, where I live, ranks first in the U.S. for longevity (长寿), according to
a Harvard School of Public Health study appearing in the Sept 12 issue of Public Library of science
Medicine.
In fact, seven Colorado counties are the top seven ranked counties in the nation, all with a life expectancy
of 81.3 years. And it hardly seems coincidental that all seven-Clear Creek, Eagle, Gilpin, Grand, Jackson,
Park and Summit-lie either on, near or neighbouring the Continental Divide and amazing beautiful.
Dr. Ned Calonge of the State Health Department said there"s nothing magical about high-country air. He
thinks the longevity results are because Colorado residents have active lifestyle, low smoking rates and the
lowest-in-the-nation numbers for obesity (超重).
Maybe.
But I"d beg to differ on the "nothing magical" part. How can you taste water just five miles from its
snowfield source-before any treated waste comes close to touching it-and not boom, even if just a little?
Studies have shown that prisoners and hospital patients do better if they have at least visual access to the
natural world.
Nature doesn"t heal everyone, of course. There are tourists come to Colorado"s high country and end
up with blinding headaches and debilitating nausea (恶心) from the altitude. There are locals who, reaching
a certain age, ran away with their oxygen bottles to Denver.
But among those who stay, there"s at least one constant: even in their old age, people remain full of life.
The question is why?
It could be the space. In Clear Creek County, there are 184 191 acres of public land, which means
approximately 19.75 acres of national forest for each of our 9 322 residents. You don"t spend a lot of time
waiting in lines.
Or is it the entertainment? Of the top seven counties, only Gilpin has a state park, portions of two national
forests, and no supermarket at all. One thing is certain: money doesn"t buy old age. In Jackson County,
which has a population of just 1 454, the median household income is only $31 821, that"s much less than
the national average of $41 994.

Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just
fat. After trying all sort of diets that didn"t work, she had to go to the stomach-bypass surgery (胃部迂回手
术), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most.
Result: she simply couldn"t eat the way she used to. In three years, Wilson is one third of her former weight.
Wilson"s experience is not all that unusual, and while doctors still aren"t exactly sure what is going on, a
report in last week"s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may
be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason
we feel hungry and it"s hard for dieters to keep weight off.
Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the
leading Dr. David of the University of Washington says, "I feel very solid about two of them." The first is that
ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is
that ghrelin levels are higher on average in people who have lost weight from dieting.
Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as
most people of normal weight. After all, ghrelin is produced by cells in the stomach Years ago, leptin, a
hormone was found as an appetite suppressant (食物抑制剂). But after years of trying, it had to be given up.
What doctors suspect is that both leptin and ghrelin are part of a complex system of brain and body
chemicals that govern weight and appetite. That does not mean pharmaceutical (药物的) weight control is
forever out of the question. "In the next ten years, we will be able to develop new drugs to help people lose
weight healthily and effectively."
B. People who have lost weight have less ghreilin in their body.
C. Without ghrelin, people are really difficult to lose weight.
D. Ghrelin is something produced by cells in the stomach.
B. There is less ghrelin in the bypass patients.
C. New drugs will be developed in 10 years.
D. Ghrelin levels are higher in people on diet.
B. hormone and medicine
C. brain and body chemicals
D. stomach and food
B. Doctors managed to use leptin to control the appetite.
C. Doctors are optimistic about how to lose weight healthily.
D. The loss of appetite in bypass patient is linked to leptin.

Supported by the former US vice-president Al Gore and other environmentalists, the boss of Virgin
Atlantic airlines called for scientists to come up with a way to take greenhouse gases out of the atmosphere.
"What we are doing is making sure we get the most carbon dioxide-friendly planes. We promise that
100% of profits we make from our transportation business are put into things like the prize we"ve offered
today. We shall convince people that we are facing a threat which is urgent and there"s no superhero. We
have no hope of a meaningful solution unless we find a way to work together." he said.
Mr Gore said global warming was man-made and was like to the planet suffering from a "fever". He said,
"Humans had slipped into a way of thinking that was centered on "shortterm satisfaction", and now meet the
challenge of transforming ourselves and changing the structures of everything we do"," he said.
Reacting to the launch of the prize, Tony Jupiter, the Friends of the Earth"s director, warned against
wasting time waiting for new inventions. He said, "Sir Richard"s initiative (初衷) may encourage inventors
to develop a wonder technology to deal with carbon dioxide of the atmosphere. But many of the ways, such
as energy efficiency and renewables, already exist, and it is essential that these be put into practice as soon
as possible. Moreover, Sir Richard must also look at his business activities and the contribution they make
to climate change. The world will find it very difficult to settle climate change if air travel continues to expand
and space tourism is developed."

C. the boss of Virgin Atlantic airlines

Lead poisoning (铅中毒) occurs when lead is present in high levels in the blood of a person. It is one of
the most common medical problems found in children. And it"s important to recognize the presence of lead
in children"s bodies because lead is very harmful.
Children have the tendency to go around and put things in their mouths like paint peelings. This is one
of the main causes of lead poisoning. It has also been found that children born in poor families have higher
chances of getting exposed to lead.
Some of the common symptoms of lead poisoning in children are headaches, stomach pains hair loss,
muscle weakness, and weight loss, etc.
Lead poisoning can have severe effects and can lead to heart diseases, kidney diseases and neurological
(神经系统的) problems. It can also result in mental dullness and a low I.Q. level. There have been cases
where lead poisoning proved to be terminal for children.
It"s difficult to easily recognize whether a child is affected by lead poisonig, as the symptoms of this
disease can occur due to some other medical problems. Therefore, children under the age of 6 should
regularly be checked to know the level of lead in their blood through blood tests. It"s possible to completely
cure a child with lead poisoning through treatment. Usually the oral medicine chelator (螯合剂) is given to
the children. Sometimes, children are given an injection (注射) for reducing the lead level. Children who
have very high level of lead in their blood would need treatment for a long period of time and would also be
put on a special diet.
Parents have to take certain precautions to lower the chance of lead poisoning in children. Cleaning the
house regularly and removing shoes at the door after coming in from outside will prevent the lead particles
from entering the house. Children should be put on a healthy diet, containing high proportionsnclud of
calcium and iron, such as eggs, milk, fruits, potatoes, etc., which helps to keep the lead levels in control,
in the children"s bodies.
In short, it"s a must to be cautious and careful, and protect your children from the horrible consequences
of lead poisoning.
